  • Rhythmic sampling and competition of target and distractor in a motion detection task

    Rhythmic sampling and competition of target and distractor in a motion detection task

    Sustained visual attention is required in many real-life situations such as driving a vehicle or operating machinery and is characterized by limited capacity; not all information available to the visual system can be processed in-depth. Recent work has suggested that to manage the limited capacity problem, the visual system samples the attended information in a rhythmic fashion, mediated by low-frequency intrinsic brain oscillations (Chota et al., 2022; Dugué et al., 2015; Fiebelkorn et al., 2013; Fiebelkorn et al., 2018; Fiebelkorn and Kastner, 2019; Helfrich et al., 2018; Michel et al., 2022; Re et al., 2019; VanRullen, 2013; Zalta et al., 2020). In this view, the cycle of a low-frequency intrinsic brain oscillation can be divided into two phases: a high excitability phase and a low excitability phase. When a stimulus occurs during the high excitability phase, behavioral performance tends to be better than average; conversely, if the stimulus occurs during the low excitability phase, performance is generally worse than average (Lakatos et al., 2008; VanRullen, 2013). Behavioral performance may thus exhibit rhythmic fluctuations at the frequency of the aforementioned low-frequency intrinsic brain oscillation. One paradigm that has been used to test the idea of rhythmic visual sampling is the cue-target paradigm (Posner, 1980; Posner et al., 1987; Posner et al., 1988). The cue at the beginning of each trial, in addition to providing instructions on how the impending target stimulus should be responded to, helps to reset the phase of the low-frequency intrinsic oscillation such that all the trials start at approximately the same phase. By varying the stimulus onset asynchrony (SOA) between the cue and the target, one obtains the behavioral response (e.g. accuracy and/or reaction time) as a function of the SOA. The rhythmic nature and the frequency of this function can then be assessed by applying time-domain and/or spectral-domain analysis.

    When attending to one object in isolation, the frequency of rhythmic sampling tends to be in the high theta or low alpha frequency range, i.e., around 8 Hz (Fiebelkorn et al., 2013; Senoussi et al., 2019; van der Werf et al., 2023). When attention is directed to multiple objects in the environment, it has been suggested that rather than sampling all the objects simultaneously, the brain samples the objects in a serial fashion (Cohen et al., 1990; Wyart et al., 2012). This would then lead to a slower rhythmic sampling of any given object, in the low range of the theta frequency band, i.e., around 4 Hz (Thigpen et al., 2019). For example, when participants were cued to attend one visual hemifield but were asked to detect the appearance of a weak stimulus in either the cued or the uncued visual hemifield, the rhythmic detection rate for the target appearing in a given visual hemifield decreased from 8 Hz to 4 Hz (Chota et al., 2022; Fiebelkorn et al., 2013; VanRullen, 2013). Interestingly, when the detection rate functions of the cued and uncued targets were compared, a 180-degree relative phase was apparent, suggesting that the visual system indeed sampled the two visual hemifields in a serial, alternating fashion (Fiebelkorn et al., 2013; Jiang et al., 2024). In another example, two spatially overlapping clouds of moving dots, one in red color and the other in blue color, moved in orthogonal directions (Re et al., 2019), and the participant was cued to attend both the red dots and the blue dots and instructed to report the change in either the red dots or the blue dots as soon as it occurred. When there was only one cloud of moving dots, the detection accuracy exhibited rhythmic fluctuations as a function of the SOA at a frequency around 8 Hz. When both clouds of moving dots were present, rhythmic fluctuations in the accuracy of detecting changes in a given cloud of moving dots were again identified, and the sampling frequency was reduced to 4 Hz. In this case, however, no apparent 180-degree relative phase between the rhythmic behavioral response functions to the red and blue dots was found, suggesting that there was no serial, alternating sampling between the two attended objects if they appeared at the same spatial location.

     The real world visual environment contains both task-relevant information (target) and task-irrelevant (distractor) information. It is well established that in the presence of a distractor, the processing of the target is negatively impacted, leading to reduced task performance (Lavie, 2005; Murphy et al., 2016). This implies that the distractor, despite the need for it to be suppressed by the brain’s executive control system (Kastner et al., 1998; Kastner et al., 1999; Kastner and Pinsk, 2004; Seidl et al., 2012; Kastner and Ungerleider, 2000), is nevertheless processed in the brain, and the competition between the target and the distractor at the neural representational level causes the detriment in behavioral performance. Does the rhythmic sampling theory extend to the target-distractor scenario? If so, what is the temporal relationship between the rhythmic sampling of attended vs distracting stimuli? These questions have hitherto not been addressed. Part of the reason is that the majority of the studies on rhythmic environmental sampling focuses on behavioral evidence, e.g., rhythmicity in the aforementioned performance-vs-SOA function (Fiebelkorn and Kastner, 2019; Landau and Fries, 2012). Since the distractor is not responded to, its sampling by the visual system cannot be inferred purely on the basis of response behavior, and consequently, it is also not possible to study how the target and the distractor might compete for neural representations purely behaviorally.

     In this study, we addressed these limitations by recording neural activities and investigating rhythmic sampling during a target-distractor scenario using steady-state visual evoked potential (SSVEP) frequency tagging. The stimuli were a cloud of randomly moving dots (the target) superimposed on emotional images from the International Affective Picture System (IAPS; Lang et al., 1997) (the distractor). The target and the distractor were flickered at two different frequencies for an extended duration of ~12 s. The participants were asked to focus on the randomly moving dots and report the number of times the dots moved coherently. In this paradigm, the onset of the stimulus array is the event that resets the phase of the putative low-frequency brain oscillation underlying rhythmic sampling, and the time from the stimulus array onset, referred to as time-from-onset (TFO), is analogous to the SOA in the traditional cue-target paradigm. It is worth noting that, although this paradigm has been used extensively in studies of target-distractor competition with electroencephalography (EEG) (Hindi Attar and Müller, 2012; Müller et al., 2008), it has not yet been examined in the context of rhythmic sampling. Aided by frequency tagging, from the EEG data, we extracted neural representations of target and distractor processing separately as a function of TFO. By examining the rhythmicity of these representations as functions of TFO and the phase relationship between these functions, we assessed (1) whether the target and the distractor were sampled rhythmically and (2) how their temporal competition for neural representations impacted behavioral performance.

  • Short-Term Inflation Expectations Decline; Labor Market Expectations Mixed

    NEW YORK—The Federal Reserve Bank of New York’s Center for Microeconomic Data today released the October 2025 Survey of Consumer Expectations, which shows that households’ inflation expectations decreased at the short-term horizon and remained unchanged at the medium- and longer-term horizons. Unemployment rate and job finding expectations worsened, while job loss expectations slightly improved. Spending and household income growth expectations remained largely unchanged. Perceptions and expectations about credit availability improved, but respondents were somewhat less optimistic about their future household financial situation. The survey was fielded from October 1 through October 31, 2025.

    The main findings from the October 2025 Survey are:

    Inflation

    • Median inflation expectations decreased by 0.2 percentage point to 3.2% at the one-year-ahead horizon in October. They were unchanged at the three-year- (3.0%) and five-year-ahead (3.0%) horizons. The survey’s measure of disagreement across respondents (the difference between the 75th and 25th percentiles of inflation expectations) increased at all horizons.
    • Median inflation uncertainty—or the uncertainty expressed regarding future inflation outcomes—remained unchanged at the one-year-ahead horizon and declined at the three- and five-year-ahead horizons.
    • Median home price growth expectations remained unchanged at 3.0% for the fifth consecutive month. This series has been moving in a narrow range between 3.0% and 3.3% since August 2023.
    • Median year-ahead commodity price change expectations declined by 0.7 percentage point for gas to 3.5% and by 0.1 percentage point for food to 5.7%. The year-ahead price change expectations increased by 1.2 percentage points for the cost of college education to 8.2%, by 0.1 percentage point for the cost of medical care to 9.4% (the highest reading since February 2023), and by 0.2 percentage point for rent to 7.2%.

    Labor Market

    • Median one-year-ahead earnings growth expectations increased by 0.2 percentage point to 2.6% in October, remaining below its 12-month trailing average of 2.7%. The series has been moving within the range between 2.4% and 3.0% since May 2021.
    • Mean unemployment expectations—or the mean probability that the U.S. unemployment rate will be higher one year from now—increased by 1.4 percentage points to 42.5%. This is the third consecutive increase in the series.
    • The mean perceived probability of losing one’s job in the next 12 months retreated by 0.9 percentage point to 14.0%. The reading is just below the series’ 12-month trailing average of 14.2%. The mean probability of leaving one’s job voluntarily, or the expected quit rate, in the next 12 months decreased by 1.9 percentage points to 18.8%, falling just below its 12-month trailing average of 19.0%.
    • The mean perceived probability of finding a job if one’s current job was lost fell by 0.6 percentage point to 46.8%, remaining well below its 12-month trailing average of 50.6%. The decline was driven by respondents below age 60 and those with at least some college education.

    Household Finance

    • The median expected growth in household income declined by 0.1 percentage point to 2.8% in October, after remaining unchanged for three consecutive months at 2.9%.
    • Median one-year-ahead household spending growth expectations increased by 0.1 percentage point to 4.8%. The series has been moving in a range between 4.7% and 5.2% since February 2025.
    • Perceptions of credit access compared to a year ago improved with a smaller share of households reporting it is harder to get credit (the lowest since February 2022) and a larger share of households reporting it is easier to get credit (the highest since October 2024). Expectations for future credit availability also improved, with a smaller share of respondents expecting it will be harder to obtain credit and a larger share of respondents expecting it will be easier to obtain credit in the year ahead.
    • The average perceived probability of missing a minimum debt payment over the next three months increased by 0.5 percentage point to 13.1%, remaining below its 12-month trailing average of 13.3%.
    • The median expectation regarding a year-ahead change in taxes at current income level decreased by 0.4 percentage point to 3.2%.
    • Median year-ahead expected growth in government debt declined by 0.3 percentage point to 7.2%.
    • The mean perceived probability that the average interest rate on saving accounts will be higher in 12 months remained unchanged at 24.9%.
    • Perceptions about households’ current financial situations compared to a year ago worsened with a larger share of households reporting a worse financial situation. Year-ahead expectations about households’ financial situations also deteriorated. A larger share of households are expecting a worse financial situation, and a smaller share of households are expecting a better financial situation in one year from now.
    • The mean perceived probability that U.S. stock prices will be higher 12 months from now decreased by 0.9 percentage point to 38.9%.

     
    About the Survey of Consumer Expectations (SCE)

    The SCE contains information about how consumers expect overall inflation and prices for food, gas, housing, and education to behave. It also provides insight into Americans’ views about job prospects and earnings growth and their expectations about future spending and access to credit. The SCE also provides measures of uncertainty regarding consumers’ outlooks. Expectations are also available by age, geography, income, education, and numeracy. 

    The SCE is a nationally representative, internet-based survey of a rotating panel of approximately 1,300 household heads. Respondents participate in the panel for up to 12 months, with a roughly equal number rotating in and out of the panel each month. Unlike comparable surveys based on repeated cross-sections with a different set of respondents in each wave, this panel allows us to observe the changes in expectations and behavior of the same individuals over time. For further information on the SCE, please refer to an overview of the survey methodology here, the FAQs, the interactive chart guide, and the survey questionnaire.

  • A journey into creativity: inside the Kering Pavilion at CIIE 2025

    Fluid forms that strike a delicate balance between openness and intimacy: the Kering Pavilion draws inspiration from the natural environment to reflect the Group’s living, evolving force of creativity. Gently curved enclosures define individual spaces where each House reveals its distinctive universe and savoir-faire. Meanwhile, open display tables, accentuated by curvilinear panels, form a landscape that invites exploration. Light filters through the panels, casting shadows and animating the displays with movement and depth.

     

    The construction itself reflects Kering sustainability commitments: modular prefabricated elements reuse 50% of materials from the previous year while, for part of the furniture, traditional leather is replaced with full-plant-life-cycle leather provided by PEELSPHERE, the first-place winner of the 2nd Kering Generation Award China.

  • ‘We’re sick of the OnlyFans model’: Stella Barey’s porn site lets gen Z sex workers have a life | Sex work

    ‘We’re sick of the OnlyFans model’: Stella Barey’s porn site lets gen Z sex workers have a life | Sex work

    Stella Barey has an hour for lunch. At 1.30pm, she loads her banged-up Tacoma with her three Belgian malinois and drives to a secret Los Angeles hiking trail. There, she gulps down a tapioca pudding and laces up her sneakers. After checking over her shoulder for foot traffic, she pulls down her brown sweatpants and jiggles her bare ass for the camera. Then come the undies. Her coiffed landing strip hovers above the rocks as a rush of urine floods the trail. Every mile she walks, she films another video: a flash, a moon, a finger up the ass.

    When Barey decided in 2020 to pursue porn full-time, she did not imagine that at 28 she would spend more time hunched over a desk – not in the fun way – making flow charts, scheduling Zoom calls, and sending pitch decks. “I’m at my happiest when I’m making a video like putting a strawberry in my butt and pushing it out,” she says. “Now I’m on calls all day and I have tech neck.” Known online as the “Anal Princess”, with large, blinking Shelley Duvall eyes and an American Girl doll pout, she will try anything once – even the title “tech founder”.

    Barey is looking to disrupt the porn landscape with Hidden, a site designed to alleviate creator burnout and restore the fun in making and consuming adult content – a place where, unlike OnlyFans, she can post public exposure and piss clips from her daily lunch-break hikes.

    Hidden arrives during an uncertain time for porn, especially for gen Z. They are skeptical of it, raised on it and increasingly behind the camera themselves. The platform reflects the DIY sensibility that Barey’s generation grew up with, and its mission speaks to their conflicted relationship with big tech, sex work and making a living online. “At the end of the day, Hidden is more than porn,” Barey says. “It’s a political statement” – and one of the only sex worker-founded sex-tech companies hosting adult content today.

    Born in San Juan Capistrano, California and raised by a gynaecologist mother, Barey cannot remember a time when she was not insatiably curious about her body. At NYU, she invented her own major – ethical healthcare systems and policy – then finished med school prerequisites for gynaecology at University of California, Los Angeles, where she gravitated to the city’s X-rated underbelly: sex parties, industry mixers, late-night friendships with porn girls. Trapped in her apartment during the first wave of Covid, grinding through schoolwork, she started experimenting with anal sex with her then boyfriend – and sharing her sexploits via dirty story times on TikTok. “This is when TikTok still felt like this hidden little piece of the internet,” she recalls.

    Her third video went viral. Men in the comments wanted her OnlyFans. Women wanted more story times. By 2021, Barey had given them both. OnlyFans bikini shots and nude selfies pulled in more than $40,000 a month – enough to make medical school look optional. She dropped out, figuring the white coat would wait for her. On TikTok, she became the horny professor to a cult following of gen Z women, quoting Michel Foucault, Sigmund Freud and Marquis de Sade as she spoke about the color of her vagina, STD checks, treating bacterial vaginosis (BV) and inserting a menstrual sponge – and the delights of anal sex.

    “I was making the sacrifice of potentially ruining my reputation to speak about sexual health and sexual topics, things 99% of the girls my age are also thinking about, in a non-stigmatized way,” Barey says. (Having a gynaecologist mom on speed dial helped.) By 2022, she had hit 750,000 TikTok followers and a $285,000 month on OnlyFans.

    It didn’t last. Four years prior, in 2018, federal law made websites legally liable for hosting material linked to sex trafficking. Spooked by the law as well as mounting pressure from banks, advertisers and religious lobbying groups, Instagram and TikTok began issuing “community violations” for even the hint of sexual content. The word obscenity, long the legal standard for what counts as “too sexual”, remained deliberately undefined, giving them carte blanche to remove anything that made them nervous. Adult creators were shadowbanned, deleted and demonetized without warning. But they could not afford to leave the mainstream platforms altogether – that’s where they advertised their content and built fanbases.

    To survive, they developed their own internet survival codes, resorting to “algospeak” to circumvent obscenity guidances (“corn” for porn, “seggs” for sex, “accountant” for sex worker), VPNs and burner accounts to evade detection, and private Discords to swap intel. “We became outlaws,” Barey says. “You have no clue what is allowed or not allowed until you get hit with a violation. It’s all word of mouth.”

    By the end of 2022, Barey had gone through 22 TikTok accounts, many with more than 600,000 followers, buying burner phones to start from scratch each time she got booted from the platform.

    Severely limited by mainstream sites, sex workers sought out new havens for posting adult content, the most popular of which is OnlyFans. Whereas Pornhub and its peers monetize traffic through ads and streaming, OnlyFans monetizes relationships, letting creators sell directly to fans. By 2024, more than 4.6 million creators were pulling in $7.2bn from subscribers. But OnlyFans comes with its own set of problems. The platform is notorious for lacking creator-friendly tools. Unlike Instagram or TikTok, there is no “explore” page or discovery feed; the burden of finding an audience falls entirely on the performer, which means relentless self-promotion on the very sites that are so hostile to them. “People don’t realize that most of these girls don’t want to be doing social media – they just want to make porn,” Barey says.

    Once fans do make it to a creator’s page, monthly subscriptions account for only a fraction of potential earnings. The real money comes from time-consuming manual engagement, such as selling custom videos, sexts and one-to-one messaging. At one point, 70% of Barey’s income came from these direct messages. “You can’t be spending your entire day making content, promoting it on socials, and also be on your account selling to fans 24/7,” she says. “It’s unsustainable.”

    The idea for Hidden began in 2023, when a high school friend and Wharton business school grad approached Barey about co-founding a porn site. Barey set the terms: a platform designed by and for sex workers, built to promote passive income in an industry where constant performance is often the price of survival. The platform launched on 12 April with a sleek black interface and artful branding. Focused on amateur content, it recalls the Tumblr-era cam girl aesthetic – a period many creators look back on with fondness. (“Hidden” is a reference to the phone folder in which normies keep their nudes.)

    After clicking “18+”, users land on a TikTok-style “For You” page that serves clips tailored to their taste. Scrolling through videos and photos, one can find anything from a girl-next-door-type smiling in her pyjamas to a performer gyrating on a lubed-up dildo. See someone you like? A quick swipe to that creator’s profile is usually where the first paywall appears: a small fee to unlock their feed, view explicit posts or send a message.

    Barey is most excited about the ways Hidden, unlike OnlyFans, helps creators keep earning without constantly filming or messaging. The site’s algorithm promotes old videos as much as new ones, and each profile includes a built-in store where fans can buy clips and pay-per-view posts – content that creators have already made, now working for them in the background.

    None of Hidden’s features are brand new, Barey admits. The scrolling feed is lifted from RedGifs; the store from ManyVids; and the chargeback protections, popular among creators for making it harder for customers to dispute charges and get refunds, from SextPanther. But they are consolidated on Hidden, which also takes the smallest cut in the industry (18% of creators’ earnings, compared with OnlyFans’ 20%).

    For Leila Lewis, 28, a Philadelphia-based creator making over $30,000 a month on OnlyFans, the appeal was immediate. “Everyone is getting sick of the OnlyFans model. We’re exhausted and burnt out,” she says. After a consultation with Barey, she said Hidden felt like a return to the golden days – something that finally made her excited about the work again. “You can’t do fisting or pee content on OnlyFans,” which is the content her fans like best but is prohibited on the more skittish platform, Lewis explains. “That’s why I love Hidden, because they just let you do pretty much anything.”

    Barey oversees a 40-person software team, a product designer and six content moderators, and more features are on the way. Barey and her team are building a takedown bot to scan the internet for leaks and stolen content with a single click. She is experimenting with AI tools that would let fans request personalized clips generated from a performer’s likeness (for instance, “me in a red dress on a plane”), while safeguarding ownership of their likeness from sites that are already selling nonconsensual AI versions of them. Barey even wants Hidden to handle its own payments instead of relying on third-party payment processors – an unheard-of move in the adult industry that would cut out the middlemen that drive up fees. (If she could buy a bank outright, she says, creators might one day keep nearly all of what they earn.)

    Ultimately, she insists it’s sex workers who will decide what comes next for Hidden. “I have a list of thousands of things, but if I’m hearing from the girls that they really want live streaming, I’m going to put that up at the top.” Meanwhile, her core crew of gen Z assistants – Drew, Chloe and Naomi, who once ran her OnlyFans and now act as her “angels” – weigh in on everything from marketing strategy to her sex tape’s final cut. Years of navigating porn sites and the minefield of social media have given them an instinct for what will resonate.

    So far, Hidden has registered over 113,000 users who have spent on average $53 each, and has enrolled more than 2,100 active creators – most of them gen Z women.


    At this moment public sentiment toward porn is souring. That’s in part due to the rise of “rage bait” porn, the kind of deliberately provocative content that first launched Barey into viral fame, when her TikTok about sleeping with her father’s fiftysomething best friend broke the internet. Gen Z creators such as Bonnie Blue and Lily Phillips, whose exhibitionist gangbang spectacles were engineered to be detested, thrive in an ecosystem warped by burnout, censorship, algorithmic whiplash, “slop” churn, and audiences with ever-shortening attention spans. For critics, they are proof the industry has lost its grip.

    The backlash also mirrors cultural anxieties about sex, gender and power among gen Z. By age 13, most US teens have already encountered pornography, often by accident. Gen Z is the first cohort to grow up with porn not just available but ambient, algorithmically unavoidable.

    The American Survey Center’s 2025 report found that nearly two-thirds of men under 25 now support making online pornography harder to access – a sharp increase from previous generations. This shift could be tied to growing discomfort with porn’s ubiquity, as well as a broader conservative turn among young people (as you can see in the “NoFap” and abstinence trends spreading across TikTok). At the same time, feminist critics, gen Z or otherwise, are calling out the damaging effects of some porn, from normalized choking to transactional “porn-script” sex bleeding into dating culture.

    Interestingly, survey data shows gen Z reports less sexual activity than earlier generations, suggesting a more cautious cohort. And yet, new Kinsey Institute research finds gen Z to be the most kink-friendly generation on record.

    Internet porn historian Noelle Perdue argues that the contradictions themselves are the story. “There is among younger generations this resentment towards the concept of mainstream pornography,” she says, “but they are also genuinely curious about their sexuality.” What gen Z is open to, she adds, is ethically produced porn that matches their sensitivities and desires. Recent Pornhub data also shows a broader cultural shift toward authenticity in porn: searches for “ethical porn” rose 92% in 2024, while “authentic sex” climbed 43%, meaning viewers are increasingly drawn to user-generated and amateur content over scripted, studio productions that can feel unrealistic.

    “Ethical porn”, a recent buzzword in the industry, generally refers to erotic content that is transparently and legally produced, fairly paid and filmed with mutual pleasure in mind; feminist porn filmmakers such as Erika Lust are often held up as the gold standard. Hidden is, in that sense, as ethical as a platform can reasonably claim to be: its content is self-filmed by age-verified performers who own their work and keep most of what they earn. However, one can never be entirely sure what is or is not ethical without being in the room where the sex is happening.

    Between her time on TikTok and an in-person erotic philosophy reading series she started last February, Barey has drawn in a wide circle of college-aged women. “I know there’s a rise in conservatism amongst gen Z, but I see this generation as the most accepting of porn of any generation yet,” she says. “They’re so supportive of sex work and understanding it as a legitimate job.”

    By the time young people have worked out what they want – or do not want – from porn, it might be a moot point. The Heritage Foundation’s Project 2025 went so far as to openly call for pornography to be outlawed and its producers imprisoned, indicating a rightwing thirst for a national ban on the industry. A less existential but more immediate threat are new age-verification laws across the US and UK that require users to upload government IDs or biometric data before accessing porn. Lawmakers frame these bills as child-protection measures, but in practice they penalize the very platforms trying to comply and slash the income of sex workers – especially queer and trans creators already working on razor-thin margins. When Louisiana’s Act 440 went into effect in 2023, Pornhub reported an 80% drop in traffic from the state, while VPN searches spiked. As Perdue notes, minors will always find adult content; what these laws actually do is punish compliant platforms like Hidden, OnlyFans and Pornhub, and funnel users toward sketchier sites rife with pirated or nonconsensual material.

    As of now, porn still accounts for more than a third of internet data transfers. Its future could depend on creators finally taking control of the industry they built. “Tech companies have a long history of establishing financial sustainability by hosting explicit content and then suddenly abandoning it,” Perdue says. “It would be amazing to have this pattern disrupted by a company that is truly aligned with sex workers, instead of just seeing adult content as a means to a financial end.”

    Three dogs pant out of open windows as Barey’s pickup barrels down the freeway, away from the hiking trail. She will miss the beginning of her 2.30pm call, a meeting with her chief technology officer to review Hidden’s next software update. There is no signal on this stretch, so for a few more minutes she can remain in her favorite role – just another horny girl on the internet with a camera roll filled with nudes.

    “Even though porn has been around forever, this version of online sex work is so brand new,” Barey says. In this way, Hidden may be less a product than a provocation – an argument that an industry dismissed as slop can still be reinvented.

  • Tech stocks head for worst week since April after $900bn AI sell-off

    Tech stocks head for worst week since April after $900bn AI sell-off

    Stay informed with free updates

    US tech stocks are on course for the worst week since President Donald Trump’s “liberation day” tariffs rocked global financial markets in April, as concerns about elevated valuations fuelled a $900bn rout in companies linked to the artificial intelligence boom.

    The market value of eight of the most valuable AI-related stocks — including Nvidia, Meta, Palantir and Oracle — has fallen by $911bn since the end of last week.

    Trading on Friday morning deepened tech investors’ losses for the week, with Nvidia falling 2.6 per cent in early trading. Other big tech companies whose share prices declined this week included Microsoft, Amazon and Broadcom. 

    The declines have left the tech-heavy Nasdaq Composite on course for a weekly loss of 4 per cent, its worst five-day run since the index fell 10 per cent after Trump launched his trade war with a flurry of tariff announcements in April.

    Nvidia, the world’s most valuable company, has fallen the most in dollar terms over the week, losing more than $430bn in market capitalisation. 

    Nvidia’s chief executive Jensen Huang told the Financial Times this week that he expected China was ultimately “going to win the AI race” against the US.

    He subsequently tried to row back on the comments, saying that China was “nanoseconds behind America in AI”, but the remarks came as the Silicon Valley chipmaker’s hopes were waning that the US government would allow it to sell a version of its latest Blackwell AI processor to Chinese customers. 

    Chinese competitors are already narrowing the technical lead held by OpenAI, Microsoft, Google, Meta and Anthropic, which are all making huge investments in AI infrastructure, much of it based on Nvidia’s chips.

    This week’s debut of Beijing-based Moonshot AI’s new Kimi K2 Thinking model was hailed as the latest breakthrough by Chinese developers, with reports suggesting it cost less than $5mn to train. 

    “Is this another DeepSeek moment?” Thomas Wolf, co-founder of AI developer platform Hugging Face, said in a social media post about Kimi. The release of DeepSeek’s low-cost R1 model sparked a Wall Street panic in January that wiped $589bn from Nvidia’s market value in a single day. 

    Comments this week by OpenAI’s finance chief Sarah Friar that the $500bn AI group might look to the US government to provide a funding “backstop” also triggered speculation about its finances.

    OpenAI’s chief executive Sam Altman sought to calm anxiety in a social media post on Thursday, saying: “We do not have or want government guarantees for OpenAI data centres.”

    He predicted that OpenAI’s revenues would “grow to hundreds of billion[s] by 2030”, though that figure may fall below its AI infrastructure commitments, which he said totalled $1.4tn over the next eight years.

    JACC Journals Publish Latest Science From AHA 2025

    AHA 2025 officially begins this weekend in New Orleans, featuring key science simultaneously published across ACC’s JACC Journals, including JACC, JACC: CardioOncology, JACC: Advances, JACC: Case Reports, JACC: Heart Failure and JACC: Cardiovascular Imaging. Highlights include:

    MESA, UK Biobank Data: Lp(a) and IL-6 Predict CHD, ASCVD Risk

    Lipoprotein a (Lp[a]) and interleukin-6 (IL-6) are independent predictors of coronary heart disease (CHD), defined as myocardial infarction or resuscitated cardiac arrest, and when combined the two biomarkers identified patients at the highest risk of CHD, according to research in two primary prevention cohorts, the Multi-Ethnic Study of Atherosclerosis (MESA) (n=6,514) and the UK Biobank (n=26,574), published in JACC.

    The hazard ratios (HRs) for CHD were 1.13 and 1.22 for Lp(a) and IL-6, respectively, in MESA and 1.11 and 1.19 in UK Biobank cohort. Similar results were found for atherosclerotic cardiovascular disease and peripheral vascular disease. The analysis conducted by Harpreet Bhatia, MD, MAS, FACC, et al., found the HRs for CHD for LP(a) plus IL-6 were 1.72 in MESA and 1.39 in the UK Biobank cohort.

    “The findings of our study support the potential incorporation of IL-6 in a primary prevention setting in addition to Lp(a); at the minimum, IL-6 may be considered a risk enhancer as it identifies individuals with increased cardiovascular risk independent of traditional risk factors, hsCRP and Lp(a),” write Bhatia and colleagues.

    ECV’s Prognostic Ability in ATTR

    Extracellular volume (ECV) identified on cardiovascular magnetic resonance (CMR) imaging provides a quantitative framework for staging and therapeutic planning in transthyretin amyloidosis (ATTR) by directly quantifying myocardial amyloid load and defining reproducible thresholds to stratify burden and refine risk prediction, according to findings published in JACC. Study authors Awais Sheikh, MBChB, et al., analyzed all-cause mortality in 1,541 patients undergoing CMR for ATTR, classified as TTR-variant carriers, extra-cardiac ATTR, early stage ATTR-CM or overt ATTR-CM. At a median 2.8-year follow-up, results showed the ECV had a strong prognostic ability with <30% excluded and ≥40% confirmed cardiac involvement, independently predicting mortality across categories: <30% none; 30-39% mild, 40-49% moderate, 50-59% moderate-severe and ≥60% severe (HR, 1.22 per 10% increase; p<0.001). “ECV outperforms traditional staging tools,” write the authors. “These data establish ECV as a quantitative biomarker that bridges clinical practice and trial design, translating amyloid biology into actionable measurement.”

    ALLSTAR: Gamification For Breast, Prostate Cancer Survivors

    Gamification increased physical activity among Black and Hispanic cancer survivors compared with attention control alone, according to research published in JACC: CardioOncology. The clinical trial randomized 150 Black and Hispanic breast and prostate cancer survivors treated with cardiotoxic therapy and with at least one risk factor for cardiovascular disease (mean age, 64 years; 81% women; 64% Black; 35% Hispanic) to either attention control (n=76) or gamification (n=74), both featuring a wearable device to track daily steps and self-determined daily step goals. Gamification participants were awarded points each week, with points lost if they did not reach their goals. Those who kept most of their points each week were moved up a level, with participants at the highest level receiving a trophy at the end of the intervention.

    Results showed that gamification participants had a greater mean daily step average and spent more time on weekly moderate-vigorous physical activity than control in both the 24-week intervention period (+759 steps, p=0.007; +16 minutes, p=0.010) and 12-week follow-up period (+581 steps, p=0.070; +11 minutes, p=0.048). Noting the greater health barriers historically marginalized communities can face within health systems, “by leveraging principles from behavioral economics, including precommitment, status quo bias, the endowment effect, goal gradients, the fresh start effect, and social accountability, the intervention addresses common barriers to behavior change,” write study authors Alexander C. Fanaroff, MD, et al.

    FH Clinical, Genetic Signs in CAD Risk Assessment

    Clinical and genetic signatures of familial hypercholesterolemia (FH) were useful in determining the risk of coronary artery disease (CAD) among patients with severe hypercholesterolemia, beyond the incorporation of LDL-C alone, according to original research published in JACC: Advances. In the retrospective study, investigators Hayato Tada, MD, et al., evaluated data from 1,273 patients (mean age, 49; 50% women) with LDL-C ≥180 mg/dL. Results showed that at a median follow-up of 12.4 years, 144 CAD events occurred. Patients with either an FH-variant (n=298) or clinical signs of FH (n=199) had a higher risk of developing CAD events (HR, 1.44, p=0.007; HR, 2.27; p<0.001, respectively). Those participants with both FH-variant and clinical signs (n=548) had a five-fold higher risk for CAD (p<0.001) after adjustment for known risk factors and LDL-C year score. “We strongly suggest assessing these clinical and genetic signatures of FH and then treating them differently based on their risk strata,” write the investigators. “These procedures may be reasonable not only for accurate diagnosis but also for personalized medicine.”

    Quality Improvement Project: Optimizing Telemetry Use

    In a quality improvement project presented in JACC: Case Reports, Hera Jamal, DO, et al., outline a low-cost, resident-led initiative that improved telemetry ordering practice at a tertiary care center. The initiative offered an educational lecture to internal medicine residents and teaching hospitalists regarding AHA best practice guidelines and posted physical reminders near telemetry stations. Results from 156 preintervention admissions and 110 postintervention showed an increase from 61% to 74% on the proportion of appropriate telemetry orders upon admission (p=0.03), although no significant change was observed at 48 hours (38% vs. 39%, p=1.00). Jamal and colleagues write on their initiative: “This is important given the established safety of discontinuing unnecessary telemetry in nonintensive care settings and the burden that continued use places on both patients and healthcare staff.”

    Survival in Patients with Advanced Symptoms of oHCM Undergoing Surgical Myectomy

    Patients with advanced symptoms of obstructive hypertrophic cardiomyopathy (oHCM) undergoing surgery myectomy (SM) had worse long-term survival compared to those with lesser symptoms – despite earlier time to surgery from initial presentation, according to research published in JACC: Heart Failure. The observational study stratified 3,546 oHCM patients by NYHA class upon initial presentation, and at a mean follow-up of 12 years recorded 698 composite events, including 661 deaths, 11 cardiac transplants and 51 appropriate ICD discharges. Even with time to initial surgery shorter in the higher classes, the number of events grew from Class I (70 events, 19% of patients) to II (232, 16%) to III (396, 23%; p<0.001). “Patients undergoing SM at an earlier symptomatic stage demonstrate superior long-term outcomes, underscoring the importance of timely referral before advanced disease occurs,” write study authors Shada Jadam, MD, et al.

    Efficacy of Treadmill Stress Echocardiography in HCM

    Treadmill stress echocardiography (TSE) has diagnostic and prognostic value in patients with asymptomatic HCM, according to a study by Sana Sultana, MD, et al., published in JACC: Cardiovascular Imaging. Of 1,299 NYHA Class I asymptomatic HCM patients undergoing TSE, 22% were found to have latent dynamic left ventricular outflow tract obstruction (LVOTO), only observed during the testing. Furthermore, 37% failed to achieve age-sex predicted metabolic equivalents (ASP-METs) ≥85%. At a mean follow-up of 12.1 years, ASP-METs <85%, undetected without TSE, was associated with increased mortality (17% vs. 12%) as well as lower survival rates at one, 10, 15 and 20 years. “The findings challenge the reliability of patient-reported symptom status and underscore the limitations of subjective self-reported assessments in clinical decision-making,” write the authors. “Whenever feasible, it is important to objectively assess functional capacity and record latent dynamic LVOTO using exercise echocardiography.”

    Artificial feeding and lifecycle completion

    The whole lifecycle of O. tholozani ticks was completed three times in consecutive experiments using the artificial feeding system in this study. In total, 5788 ticks of different life stages were tested, including 1605 larvae, 601 first-stage, 364 second-stage, and 269 third-stage nymphs, 30 females and 34 males, and 2885 eggs. The first cycle was completed in 351 days (standard error, SE = 17.35), the second cycle in 546 days (SE = 13.8), and the third cycle in 238 days (SE = 6.15) (Additional file 1: Additional Table 1). The difference between the lengths of the cycles was due to a technical reason related to the feeding system. In the second cycle, we changed the dog from which we produced the lipid hair extract since the dog used in the first cycle was no longer available. The time between the end of one lifecycle and the next, i.e., from the first oviposition of a certain tick generation until the feeding of the first batch of larvae of the next generation, ranged between 45 and 63 days [average (AV): 51.5, SE = 5.7].

    Table 1 Borrelia persica acquisition by third-stage nymphs at defined time points post infection. Presence of B. persica DNA and quantification of B. persica loads in tick organs at different time points post infection

    Reproductive capacity parameters, engorgement, and molting rates were measured for the different tick generations (Additional file 1, Table 1). The average number of eggs laid per female was 56.8, 183.7, 184.2, and 189.0, for the parent stock, first, second, and third generation, respectively. The percentage of larvae hatching was 60.2%, 91%, and 94% for the first, second, and third generations, respectively. The period of days between the female tick engorgement and oviposition was 44.2, 21.2, 28.7, and 26.4 for the parent stock, first, second, and third generation, respectively. Average percentage rates of engorgement were 81.9% (SE = 5.1), 58.0% (SE = 10.3), and 68.2% (SE = 2.3) for the first, second, and third generation, respectively; average molting rates were 56.9% (SE = 11), 85.6% (SE = 3.5), and 85.5% (SE = 3.9), for the first, second, and third generation, respectively. The average mortality rates of ticks in all three lifecycles were 7.1% (SE = 3.1), 4.5% (SE = 2.3), 2.4% (SE = 2.4), 12.2% (SE = 3.9), and 0%, for larvae, first-, second-, and third-stage nymph, and adults, respectively. Females were fed only once in their adult life prior to oviposition. Females, except for those of the parent stock and of the third generation, which were analyzed after the first oviposition, were allowed to continue with additional cycles of folliculogenesis for up to 5 months. Out of nine females belonging to the first and second generations, two females had four ovipositions, two had three ovipositions, three had two ovipositions, and two had only one oviposition. The other tick life stages were also fed only once in each life stage prior to molting, except for an additional feeding attempt that was carried out for those ticks that refused to feed in the first try, which was done a week after the first one. This part of the study showed that the whole lifecycle of O. tholozani can be reproduced under laboratory conditions exclusively by artificial feeding with no need for feeding on experimental animal hosts.

    Borrelia persica survival in bovine blood

    Follow-up of spirochete motility in the bovine blood was continued over 8 days. Motile spirochetes were observed until 96 h post-inoculation and not thereafter, supporting the idea that B. persica requires being in a tick or vertebrate host to continue its long-term survival.

    Borrelia persica acquisition by third-stage nymphs at defined time points post-infection

    Ticks raised in the laboratory, which originated from the parent stock, were brought from the egg stage to the third-stage nymphs by artificial feeding on uninfected bovine blood. At that stage, 42 third-stage nymphs were fed with heparinized bovine blood containing 10⁶ B. persica spirochetes per ml, and were divided into five groups according to the time point of analysis post-infection. The groups included ticks examined by PCR for B. persica in their guts and salivary glands, 1, 2, 3, 4, and 5 weeks after infection (Table 1). All 16 (100%) of the third-stage nymphs tested at 1 and 2 weeks after infection were found to be positive for B. persica by PCR only in their guts. At week 3, seven out of eight (87.5%) ticks tested were positive for B. persica in their guts, and one was negative in both guts and salivary glands. In the fourth week, two out of eight third-stage nymphs had molted to females and one to a male, while the remaining five stayed as third-stage nymphs. Six (75%) of these ticks were infected, including five third-stage nymphs and one female. When relating to all tick stages, B. persica DNA was found in the guts of four ticks and salivary glands from three. Two third-stage nymphs were positive in both their guts and salivary glands, two were positive only in their guts, and one was positive only in its salivary gland. The positive female was infected in its guts and its salivary glands. Of the ten ticks evaluated after 5 weeks of infection, three nymphs had molted to fourth-stage nymphs, and one had molted to a male. Infection was detected in five ticks, including five guts and one salivary gland. Three third-stage nymphs were positive only in their guts, one fourth-stage nymph was infected in its gut, and another fourth-stage nymph was infected in its gut and salivary glands. The male was negative.

    In total, out of the 42 infected third-stage nymphs in all the groups, 34 (81%) ticks (31 third-stage nymphs, two fourth-stage nymphs, and one female) were positive for B. persica by the flaB PCR, including 33 guts and 5 salivary glands, with infection of salivary glands detected only in ticks analyzed at week 4 and 5 after infection (Table 1). The average B. persica loads in the guts, expressed as Borrelia flaB copies per tick 16SrRNA gene copy, ranged between 4.7 and 67.4 in the different weeks (Table 1). The copy number of B. persica in the guts at week 1 (AV = 67.4) was significantly higher than at week 3 (AV = 5.5) and 4 (AV = 48.7) (Kruskal–Wallis test H = 8.25, df = 3, P = 0.041; Table 1). However, when comparing the B. persica loads in the guts of ticks at week 5 of infection (AV = 28.5) with those found at the other time points, only a nonsignificant trend was observed (Kruskal–Wallis test H = 8.79, df = 4, P = 0.066). The average B. persica loads in the salivary glands at weeks 4 and 5 post-infection were 7.9 flaB-copies per tick 16SrRNA gene copies (SE = 7.5), and in the guts analyzed at week 4 and 5 it was 37.46 (SE = 23.43) with no significant differences between loads in the salivary glands and in the guts with those found at the other time points (Mann–Whitney U-test: U(13) = 16.00, Z = −0.309, P = 0.825). The results described in this section portray the dynamics of B. persica within experimentally infected ticks, with movement of infection from the tick gut to the salivary glands noted from 4 weeks post-infection.

    Transstadial and transovarial transmission of B. persica

    Transstadial transmission was analyzed by infecting 161 larvae with 1.2 × 10⁷ B. persica spirochetes per ml of blood and testing 20 individuals from each tick life stage, e.g., larvae, first-, second-, and third-stage nymphs, and adult ticks (ten females and ten males). Larvae were tested 1 week after feeding on infected blood, whereas first-, second-, and third-stage nymphs were analyzed a week after molting; adults were analyzed 2 weeks after molting. Except for larvae, which were analyzed after engorgement, the remaining stages were analyzed unengorged. The rate of infection decreased from 100% (20/20, 95% CI 83.16–100%) in larvae to 55% (11/20, 95% CI 31.53–76.94%), 20% (4/20, 95% CI 5.73–43.66%), and 25% (5/20, 95% CI 8.66–49.10%) in first-, second- and third-stage nymphs, respectively. Adult ticks showed an infection rate of 20% (4/20, three male ticks and one female tick).

    Average B. persica loads in ticks were 243.8 (SE = 42.1), 21.6 (SE = 7.7), 38.1 (SE = 4.9), and 61.2 (SE = 21.9) flaB-copies per tick 16SrRNA gene copies in larvae and first-, second-, and third-stage nymphs, respectively. Average B. persica loads in adults were 199.2 flaB-copies per tick 16SrRNA gene (SE = 25.7) [244.4 (SE = 50.2) and 63.5 in males and females, respectively] (Table 2). There was a significant difference in parasite load between tick stages (Kruskal–Wallis test H = 20.18, df = 4, P < 0.001). Post hoc pairwise comparisons using Dunn’s test with Bonferroni correction indicated that the larvae had a significantly higher parasite load than first-stage nymphs (Z = 18.344, P = 0.002), but no other pairwise differences were significant.

    Table 2 Transstadial transmission of Borrelia persica infected at the larval stage

    Transovarial transmission was tested by mating eight infected females with eight uninfected males and analyzing 20 eggs and 20 larvae laid and hatched from each of the eight potentially infected females. Because only eight eggs were analyzed from one of the females, a total of 148 eggs and 160 larvae were analyzed. The number of days from feeding and engorgement of the females to the beginning of the first oviposition ranged between 21 and 44 days (average = 26.6, SE = 2.6), and the number of eggs laid per female ranged between 70 and 190 (average = 129.6, SE = 13). Larval hatching rate ranged between 67% and 85% (average = 77%, SE = 2.3). Dissection and molecular analysis of the females and males, which were infected at third-stage nymph, was done after the first oviposition between 12 and 16 weeks post-infection, and real-time PCR targeting the Borrelia flaB gene [21] was done on the salivary glands, guts, and gonads. Of the eight females, five were infected (62.5%). Three of them were positive in their guts, five in their salivary glands, and three in their ovaries. Of those, three females were positive in their guts, salivary glands, and ovaries, and two females only in their salivary glands. All eight uninfected males that were mated with the females were negative for B. persica DNA. Regarding B. persica infection in eggs, 4 of 148 eggs (2.7%) analyzed were positive by PCR. The positive eggs belonged to three positive females. Considering only the eggs laid by infected females (n = 5), the rate of egg infection was 4 of 100 (4%), ranging from 5% to 10% per infected female (Table 3). Regarding B. persica infection in larvae that hatched from the eggs of the experimentally infected ticks, 2 of 160 larvae tested were positive (1.3%), and both belonged to larvae hatched from eggs laid by one positive female. Considering only larvae derived from positive females, the rate of larvae infection was 2 of 100 (2%) and 10% per the single positive female, which gave rise to the infected larvae (Table 3).

    Table 3 Transovarial transmission of Borrelia persica to eggs and larvae from infected Ornithodoros tholozani female ticks

    Five uninfected females were paired with five uninfected males as controls. The period of days from feeding and engorgement of the adults until the beginning of the first oviposition ranged between 21 and 29 days (AV = 26.4, SE = 1.6), and the number of eggs laid per female ranged between 84 and 263 (AV = 189, SE = 29.3). The larvae hatching rate ranged between 74% and 94% (AV = 88%, SE = 3.9%). The hatching rate of the larvae originating from the control group of uninfected females (88%) was close to being significantly higher than the hatching rate of the larvae derived from B. persica-infected females (75%) (Welch’s t-test, t(5.477) = −2.49, P = 0.051).

    The outcomes of the experiments on transstadial and transovarial transmission indicated that both modes of B. persica transmission could be demonstrated by experimental infection using artificial tick feeding, and that the rate of transovarial transmission was considerably lower than that of its transstadial counterpart.

    Horizontal transmission of B. persica between ticks by hyperparasitism

    Twenty-two third-stage nymphs infected with heparinized bovine blood containing 10⁶ spirochetes per ml were divided into two groups. In the first group, each infected third-stage nymph was individually paired immediately after infection with an uninfected unfed male for 3 h to study possible direct acquisition of B. persica by the males from the nymphs. Biting of nymphs and engorgement of the males with laceration of nymph dorsal plates caused by male mouthparts were observed in three nymph-male pairs (Figs. 2A, B). Five weeks after pairing, three out of ten potentially infected and engorged nymphs molted into fourth-stage nymphs, one molted into a male, and the rest remained as third-stage nymphs. Molecular screening by real-time PCR targeting the flaB gene [21] revealed that five out of these ten ticks were positive for B. persica, including three third-stage and one fourth-stage nymph. All positive ticks showed infection in the guts, and one fourth-stage nymph showed B. persica DNA also in the salivary glands. Out of ten uninfected, unfed males before the pairing, three showed blood in their gut during their dissection, which was performed 5 weeks after pairing with the nymphs. These three males had been paired with third-stage nymphs, which showed laceration lesions in their dorsal plates after the pairing, and two of these males were positive for B. persica flaB DNA in their guts at week 5 of the experiment. These two positive males had been paired 5 weeks earlier with two nymphs that were PCR-positive, demonstrating transmission of B. persica by hyperparasitism. The third engorged male, which was negative by PCR, was paired with a nymph that turned out to be PCR-negative for B. persica when tested.

    Fig. 2

    Laceration lesion in a nymphal dorsal plate (black arrow) immediately after hyperparasitism by a male (A), and healed laceration lesion in the dorsal plate (black arrow) of the same nymph 5 weeks after the breach caused by a male (B)

    In the second group, 12 uninfected, engorged third-stage nymphs were paired individually immediately after feeding with 12 potentially infected unfed males for 3 h. After the pairing, five nymphs showed laceration of the dorsal plates and one on the ventral exoskeleton, caused by male mouthparts. Five weeks after pairing, 3 out of 12 engorged uninfected third-stage nymphs molted into males, 1 into a female and 1 into a fourth-stage nymph, and the remaining 7 remained as third-stage nymphs. Borrelia-specific flaB DNA real-time PCR screening revealed that all of the previously engorged uninfected ticks were negative for B. persica DNA, while two of the potentially infected males, which fed on the uninfected ticks, harbored B. persica DNA in their guts. In essence, B. persica was not transmitted during hyperparasitism from infected males to engorged nymphs. The results of this part of the study indicate that B. persica can be transmitted between O. tholozani ticks by feeding directly on each other.

    Molecular analysis

    All positive samples were sequenced. In total, 101 flaB DNA sequences of B. persica were obtained. From these, 38 sequences were from 38 ticks infected during the transstadial infection experiment, 38 sequences were from positive organs of 34 ticks infected weekly during 5 weeks, 17 sequences were from positive organs and offspring of infected females during the transovarial infection experiment, and 8 sequences were from organs of infected nymphs and males that participated in the hyperparasitism infection experiment. All DNA sequences were 100% identical to each other. Four DNA sequences were submitted to GenBank (accession nos. MW284983-86). Uninfected control ticks of all life stages and all DNA extractions from negative controls were PCR-negative for B. persica.

  • Hurricane Melissa triggers 100% payout of $150 million World Bank Catastrophe Bond for Jamaica

    Hurricane Melissa triggers 100% payout of $150 million World Bank Catastrophe Bond for Jamaica

    Pre-agreed parametric triggers reached for full payout based on storm’s central pressure and path

     

    WASHINGTON, NOVEMBER 7, 2025 — Following Hurricane Melissa, the Government of Jamaica will receive a full payout of $150 million under its catastrophe insurance coverage with the World Bank, backed by a catastrophe bond issued in 2024 by the World Bank (International Bank for Reconstruction and Development, or IBRD, AAA/Aaa).

    Analysis carried out by third-party calculation agent, AIR Worldwide Corporation, concluded that Hurricane Melissa reached pre-agreed parametric triggers qualifying for a full redemption of the World Bank Catastrophe Bond, which offers Jamaica financial protection against specified natural disasters. The analysis was based on the storm’s central pressure and path, as reported by the National Hurricane Center.

    As one of the most exposed countries to natural disasters, Jamaica has a well-developed disaster risk financing strategy. Jamaica initially received insurance coverage against named storm events from the World Bank through a World Bank-issued catastrophe bond in 2021 and three years later renewed its coverage with the 2024 catastrophe bond.  Further information related to the bond’s structure can be found here.

    Catastrophe bonds transfer financial risks from natural disasters to global capital markets and are one of many financial instruments available to support countries in the aftermath of natural disasters such as hurricanes and earthquakes. Catastrophe bonds are recognized by credit rating agencies as beneficial to countries and form part of their disaster risk management toolkit.

    “Our thoughts are with the people of Jamaica as they recover and rebuild from this tragedy. Jamaica’s comprehensive disaster risk management strategy and proactive approach serve as a model for countries facing similar threats and seeking to strengthen their financial resilience to natural disasters,” said Jorge Familiar, World Bank Vice President and Treasurer. “The payout underscores the role of catastrophe bonds in effective risk management strategies and their efficiency in transferring disaster risks to capital markets.”

    In addition to the forthcoming full payout of the catastrophe bond, a broad package of World Bank Group assistance is ready to be mobilized to support Jamaica — combining quick-disbursing emergency finance, the redeployment of existing project funds, and targeted private-sector support through the International Finance Corporation, the World Bank Group’s private sector development arm.

    “As Jamaica confronts the aftermath of Hurricane Melissa, its strong commitment to preparedness is proving its worth — allowing the country to move swiftly from relief to reconstruction and to use this moment not just to rebuild, but to leapfrog toward more resilient infrastructure”, said Susana Cordeiro Guerra, World Bank Vice President for Latin America and the Caribbean. “The World Bank Group stands with the Government and people of Jamaica to help rebuild stronger, restore livelihoods, and set a new benchmark for resilience across the Caribbean.”

    Catastrophe insurance backed by catastrophe bonds are part of the World Bank’s Crisis Preparedness and Response toolkit which provides developing countries with an innovative suite of tools to better respond to crises and prepare for future shocks. This includes fast access to cash for emergency response, expanded catastrophe insurance and the option to pause debt service payments in the aftermath of a natural disaster.

  • Renault Group pays tribute to Mr. Louis Schweitzer, Chairman and Chief Executive Officer of the Group from 1992 to 2005

    Renault Group pays tribute to Mr. Louis Schweitzer, Chairman and Chief Executive Officer of the Group from 1992 to 2005

    On behalf of Renault Group, I would like to pay tribute to Louis Schweitzer, a visionary and bold leader whose commitment and high standards contributed to the modernization and internationalization of the Group with iconic launches such as Twingo and Megane, the acquisition of Dacia, and the creation of the Renault-Nissan strategic Alliance. He also championed a humanistic vision of business, combining economic performance with social responsibility. We extend our sincere condolences to his family and loved ones.” said Jean-Dominique Senard, Chairman of Renault Group.

    “It is with deep sadness that I learned of the passing of Louis Schweitzer, who led our company with vision and determination. Under his leadership, Renault Group underwent major transformations. The company’s evolution bears the mark of the strategic vision he instilled. On behalf of all our employees, I would like to pay tribute to the memory of an exceptional man and offer our sincere condolences to his family and loved ones.” said François Provost, CEO of Renault Group.

    Louis Schweitzer was born on July 8, 1942 in Geneva. He studied at Sciences Po Paris, then at the Ecole nationale d’administration (ENA), from which he graduated in 1970. He began his career as an inspector of finance, a prestigious position in the French senior civil service.

    He became chief of staff to Laurent Fabius who was then Prime Minister, from 1984 to 1986. This political experience placed him at the heart of the French executive power and opened the doors to the industrial world.

    In 1986, he joined Renault Group, first as Chief Financial Officer, then as Deputy Chief Executive Officer.

    In 1992, he became Chairman and Chief Executive Officer of the Group, succeeding Raymond Levy.

    Under his leadership, Renault Group was privatized in 1996, and he orchestrated the strategic Alliance with Nissan in 1999, a major turning point for the Group. Louis Schweitzer was also the architect of the Dacia takeover in 1999, with a bold strategic vision: to create a reliable car at a very low cost for emerging markets.

    In 2005, he stepped down as Chairman of the Group.

    Louis Schweitzer is Grand Cross of the Legion of Honour.
