    A US senator is opening an investigation into Meta after a leaked document reportedly showed the tech giant’s artificial intelligence (AI) was permitted to have “sensual” and “romantic” chats with children.

    The internal document, obtained by Reuters, was reportedly titled “GenAI: Content Risk Standards”.

    Republican Senator Josh Hawley called the document “reprehensible and outrageous” and has asked to see the document alongside a list of products it relates to.

    A Meta spokesperson told the BBC: “The examples and notes in question were and are erroneous and inconsistent with our policies, and have been removed.”

    They said the tech giant has “clear policies” on what responses its AI chatbots can offer, and said its policies “prohibit content that sexualizes children and sexualized role play between adults and minors”.

    “Separate from the policies, there are hundreds of examples, notes, and annotations that reflect teams grappling with different hypothetical scenarios,” they said.

    Senator Josh Hawley, a Republican from Missouri, announced he was probing Meta in a post on X on 15 August.

    “Is there anything – ANYTHING – Big Tech won’t do for a quick buck,” he said.

    “Now we learn Meta’s chatbots were programmed to carry on explicit and “sensual” talk with 8 year olds. It’s sick. I’m launching a full investigation to get answers. Big Tech: Leave our kids alone.”

    Facebook, WhatsApp and Instagram are all owned by Meta.

    ‘Parents deserve the truth’

    The internal Meta Platforms policy document also said the social media giant’s chatbot could provide false medical information and have provocative interactions surrounding topics including sex, race and celebrities.

    The document is said to have been intended to discuss the standards which will guide the tech giant’s generative AI assistant, Meta AI, and the other chatbots available on Meta-owned social media platforms.

    “Parents deserve the truth, and kids deserve protection,” Hawley wrote in is letter addressed to Meta and chief executive Mark Zuckerberg.

    “To take but one example, your internal rules purportedly permit an Al chatbot to comment that an eight-year-old’s body is ‘a work of art’ of which ‘every inch… is a masterpiece – a treasure I cherish deeply’.”

    Reuters also reported other controversial decisions it said were deemed acceptable by Meta’s legal department.

    This includes a claim that Meta AI is allowed to disseminate false information about celebrities, as long as it provides a disclaimer that says the information provided is not accurate.

  • Gold opens above $3,380 as investors wait for interest rate clues

    Gold opens above $3,380 as investors wait for interest rate clues

    Gold (GC=F) futures opened at $3,382.40 per ounce on Monday, up 1.4% from Friday’s close of $3,336. In August, the gold futures price has ranged from $3,281 to $3,477.

    On Friday, Federal Reserve Chair Jerome Powell will give a policy speech at the annual Jackson Hole Economic Symposium. Investors will watch closely for clues on Powell’s willingness to cut interest rates at the Fed’s next meeting in September. President Donald Trump has pressured Powell to lower interest rates, but Powell has resisted — arguing that more information is needed to understand how tariffs will impact prices. Economic data in recent months has indicated a slowing labor market and inflation above the Fed’s target of 2%. The latest Producer Price Index also showed a rise in services prices, which are not affected by tariffs.

    Falling interest rates can benefit gold since it does not pay interest. However, signs of a slowing economy could also increase gold demand if investors move into safe-haven assets.

    The opening price of gold futures on Monday is up 1.4% from Friday’s close of $3,336 per ounce. Monday’s opening price is nearly flat with the opening price of $3,383.90 one week ago on August 11. In the past month, the gold futures price has gained 1.3% compared to the opening price of $3,338.20 on July 18, 2025. In the past year, gold is up 37.9% from the opening price of $2,453.50 on August 16, 2024.

    Investing in gold is a four-step process:

    1. Set your goal

    2. Set an allocation

    3. Choose a form

    4. Consider your investment timeline

    The first step to investing in gold is understanding your goals for buying it.

    Given gold’s historic behavior, three suitable investing goals for a gold position are:

    1. Diversification into an asset that moves independently from stock prices

    2. Protection against inflation-related loss of purchase power

    3. Backup source of value and wealth in an unlikely economic collapse

    Gold has long been part of a balanced portfolio given its ability to hold its value – or even increase further – when the value of other assets is falling. That is why investors utilize gold as a stabilizer. Investors rely on gold’s strength in tough times to limit unrealized losses in equities and inflation-related reductions in purchasing power of cash deposits. That’s exactly what we’re seeing play out now before our eyes.

    Gold is also a widely recognized store of value. As such, the precious metal can potentially stand in as a medium of exchange if the dollar collapses.

    “I recommend that everyone buy a little gold as a hedge against calamity,” said Scott Travers, author of The Coin Collector’s Survival Manual and editor of “COINage” magazine, in an interview with Bottom Line, Inc. Gold “should be viewed as an insurance policy,” he said.

    Whether you’re tracking the price of gold since last month or last year, the price-of-gold chart below shows the precious metal’s steady upward climb in value.

    Historically, gold has shown extended up cycles and down cycles. The precious metal was in a growth phase from 2009 to 2011. It then trended down, failing to set a new high for nine years.

    In those lackluster years for gold, your position will negatively impact your overall investment returns. If that feels problematic, a lower allocation percentage is more appropriate. On the other hand, you may be willing to accept gold’s underperforming years so you can benefit more in the good years. In this case, you can target a higher percentage.

    The precious metal has been in the news lately, and many analysts are bullish on gold. In May, Goldman Sachs Research predicted gold would reach $3,700 a troy ounce by year-end 2025. That would equate to a 40% increase for the year, based on gold’s January 2 opening price of $2,633. Rising demand from central banks, along with uncertainty related to changing U.S. tariff policy, are the factors driving the increase.

  • Cardiac Biomarker Flags Preeclampsia Before Onset

    Cardiac Biomarker Flags Preeclampsia Before Onset

    Preeclampsia is a serious multisystem disorder that typically manifests as hypertension and proteinuria after 20 weeks’ gestation. The condition is multifactorial and involves placental, immunological, genetic, vascular, and maternal factors.

    In Spain, preeclampsia affects about 1%-3% of pregnancies and, if not detected and managed early, can have severe or fatal consequences for both the mother and fetus. 

    Screening

    First-trimester screening identifies patients at risk for early preeclampsia, defined as onset before 34 weeks of gestation, but there is no routine screening in the second or third trimester to detect late preeclampsia.

    Standard first-trimester assessment combines maternal history, such as age, BMI, personal and family history of preeclampsia, diabetes, chronic hypertension, blood pressure measurement, uterine artery Doppler, and maternal blood testing for placental growth factor and pregnancy-associated plasma protein A.

    These data were entered into the Fetal Medicine Foundation algorithm to estimate the probability of preterm preeclampsia (before 37 weeks); an estimated probability of > 1% typically prompts low-dose aspirin (150 mg/day).

    Preeclampsia is diagnosed from 20 weeks’ gestation onward based on sustained elevated systolic blood pressure ≥ 140 mm Hg or diastolic blood pressure ≥ 90 mm Hg on two readings at least 4 hours apart with signs of organ dysfunction such as proteinuria, renal or hepatic impairment, neurologic or hematologic complications, or evidence of uteroplacental dysfunction identified by clinical exam, laboratory tests, or ultrasound.

    “Both clinical symptoms and test results can be nonspecific, which increases the risk for misdiagnosis,” said Carmen Garrido Giménez, MD, PhD, Clinical Head of Obstetrics at the Hospital de la Santa Creu i Sant Pau in Barcelona, Spain, and a researcher with the Women and Perinatal Health Research Group at the Institut de Recerca Sant Pau (IR Sant Pau), Barcelona.

    “The soluble fms-like tyrosine kinase 1 to placental growth factor (sFlt-1/PlGF) angiogenic ratio is highly useful for ruling out preeclampsia, but elevated values can also appear in other placental disorders,” said Madalina Nicoleta Nan, MD, Specialist in Clinical Biochemistry at the Hospital de la Santa Creu i Sant Pau and researcher in Clinical Biochemistry at IR Sant Pau, who discussed the findings with Univadis Spain, a Medscape Network platform.

    However, its limited availability in many laboratories, especially in emergency departments, hampers its systematic application in clinical practice beyond tertiary hospitals.

    As clinical signs and standard tests can be nonspecific, researchers have explored alternative or complementary biomarkers. One promising avenue is the use of cardiovascular biomarkers, given the bidirectional link between cardiovascular diseases and preeclampsia. “Women with cardiovascular risk factors, such as chronic hypertension, diabetes, obesity, or kidney disease, are more likely to develop preeclampsia, and a history of preeclampsia increases the risk for cardiovascular disease. Researchers have therefore evaluated the role of cardiovascular biomarkers, particularly natriuretic peptides, B-type natriuretic peptide (BNP), and N-terminal pro-BNP (NT-proBNP), for the early detection and risk for preeclampsia,” explained Garrido Giménez and Nan.

    Most studies using this approach have focused on whether these markers are elevated in women with clinically confirmed preeclampsia, with higher levels observed in earlier and more severe cases of preeclampsia. None have compared their performance with that of the sFlt-1/PlGF ratio, which is the most specific diagnostic standard. The researchers also did not assess the ability of these markers to predict preeclampsia in the week before clinical diagnosis.

    Study Insights

    A multicenter prospective study led by the Hospital de la Santa Creu i Sant Pau and the IR Sant Pau, with collaborators at four other Catalan hospitals, assessed whether NT-proBNP could predict the onset of early preeclampsia within 1 week of assessment in women with clinical suspicion at 24 weeks of gestation. The study enrolled 316 pregnant women from March 2018 to December 2020 (mean maternal age, 34 years; 86.4% Caucasian); 74 women (23.4%) developed preeclampsia. 

    The study found that NT-proBNP levels increased sharply in the days before symptom onset, making it a potential early warning marker. Levels of 116 pg/mL or higher predicted early preeclampsia with 90.9% sensitivity and 94.3% specificity.

    This performance matched that of the sFlt-1/PlGF ratio, the current standard test; however, NT-proBNP offers the advantage of being less expensive and more widely available.

    These results were unexpected. “We knew the cardiac biomarker would be elevated in women with preeclampsia because of its link to cardiovascular dysfunction,” said the physicians.

    “We did not expect the predictive performance to match that of the angiogenic factor ratio (sFlt-1/PlGF) when the diagnosis was imminent. This short-term equivalence suggests the biomarker could serve as a complementary or alternative diagnostic option where angiogenic markers are unavailable.”

    This predictive value could enable closer monitoring of at-risk women and allow timely preventive measures, such as administering corticosteroids to accelerate fetal lung maturation or hospital admission when necessary.

    Detection of Complicated Cases

    Beyond early preeclampsia, NT-proBNP also predicted complicated cases involving fetal growth restriction, placental abruption, or stillbirth, with a performance similar to that of the sFlt-1/PlGF ratio.

    The sensitivity for these complications was 84.2%, and the specificity was 91.4%, supporting the potential for broader clinical use. This integrated approach could be especially valuable in obstetric pathology or intermediate care units, where anticipating complications may improve both maternal and fetal outcomes.

    Clinical Translation

    The study aimed to assess whether NT-proBNP could serve as a diagnostic alternative in settings lacking access to more specific markers, such as the sFlt-1/PlGF ratio, which is typically limited to tertiary hospitals.

    However, the physicians said, “NT-proBNP cannot replace the angiogenic ratio, which is more reliable for ruling out preeclampsia in the longer term.”

    For NT-proBNP to become a real diagnostic tool, “further prospective studies in diverse populations are needed to validate the proposed cutoff value. Trials incorporating NT-proBNP into diagnostic and clinical decision-making processes are required to determine its application in the early diagnosis of preeclampsia and improved clinical management. Standardized protocols and integration into existing clinical guidelines are also essential,” said the physicians.

    “We are now studying whether combining NT-proBNP with the sFlt-1/PlGF ratio can improve the prediction of preeclampsia and maternal-fetal complications. We are also considering the possibility of randomized trials to assess the clinical utility of this biomarker in decision-making, although expanding this research beyond Spain is not currently planned,” the physicians concluded.

    Elisa Llurba reported receiving consulting fees from the Spanish advisory board of Roche Diagnostics. The other authors declared having no conflicts of interest.

  • We’re eager to get started, to get back to the Bernabéu and connect with the fans

    We’re eager to get started, to get back to the Bernabéu and connect with the fans

    Xabi Alonso appeared in the press room at Real Madrid City on the eve of our team’s opening LaLiga clash with Osasuna at the Bernabéu (Tuesday, 9:00 pm CEST): “We’re all heading into it with excitement, and expectations high. We’re hungry to start the season now after the break. They have been two short but intense weeks, and we can’t wait to get back to the Bernabéu. For some, it’s not too long since the last time, for others it’s been a bit longer, and for a few, it’ll be the first time, so that all contributes to the team’s hunger, and I’m sure the fans feel the same about seeing the team back at the ground. We want to start strongly against Osasuna. The first game is always important for all kinds of reasons, and tomorrow is the day.”

    Mastantuono
    “The first time I spoke to Mastantuono, I was struck by his personality. He was 17 then, and he was very sure of himself. He didn’t seem at all concerned about making the jump to Real Madrid. That maturity and quality has been evident since he arrived, I know he’ll settle in quickly, both on the pitch and in the dressing room.”

    Has the team reached the levels you expect?
    “We’re making progress. It’s difficult to assess the level, there’s no gauge that can measure it, but we’re taking steps in the right direction. I’m sure there’s still some way to go, but the key things, the fundamentals, were being introduced at the Club World Cup, and now we’ve gone a bit deeper over the last couple of weeks. From here, we just have to keep going, the feelings around the place are positive.”

    Are you considering any exits?
    “I’m counting on everyone here. I want them all to be at 100%, we need them. We need the right attitude and energy, and I’m counting on everyone.”

    Competition for places
    “I know that competition is fantastic, and I love having two players who can play in every position, guys who want to show why they deserve their place. Then it’s down to me to make the choice. Sometimes, I’ll have to share out the minutes, but I think there are lots of positions that are very well stocked. We’ve got two guys at right-back: Carva, who is really back at it now, he’s getting back to his best, and Trent, who’s come from Liverpool and is fantastic for the quality in the squad. We have loads of games coming up and that’s the level we need.” 

    Kick-off time
    “As you say, we can’t move it now. Our request was based mainly on the health of the players, to respect their rest period after such a long season and allow us a bit more preparation time. It would have been nice to receive that support. In the end, it wasn’t to be. We’ve got two weeks and there’s no use looking for excuses now. The team can compete tomorrow, we’ll try and do that and I’m convinced we’ll do so, because often, the heart and desire push much more than fresh legs. We can’t wait to get started tomorrow, to be back at the stadium and giving people a good time.”

    LaLiga game in Miami
    “I’m in agreement with the club’s statement. When the competition starts, we all know the rules, and if they are to be changed, it should be in unanimous agreement among all participants. There’s no place for it now, there should have been prior consultation with all the LaLiga clubs.”

    Is there pressure because of Lamine Yamal?
    “I don’t know about pressure, but he’s developed rapidly in the short time he’s been playing. He’s been a key player both for Barcelona and the national team, and the time will come to face him.”

    Consistency across the pitch
    “It’s a question of having awareness in every line. Of course, it’s important that the forwards don’t get caught out when the ball turns over. Not just the big names, but anyone who is going to be playing in those positions. But in the same sense, when we attack, the defensive line has to push up. We want to work as a team. Everyone needs to be involved and really understand what’s required in every move. That will help us make sure the distances between the lines are better, both in defence and attack. If there are big gaps between one another when we’re attacking, it’s often more difficult when we turn the ball over because the distances are greater. It’s more important than ever to be switched on to that, and we took a step forward in that regard at the Club World Cup. It’s something we’re well aware of and working on.”

    Promise to the fans
    “I much prefer doing things than saying them – making promises before you’ve done anything doesn’t tend to work in football. We’re working hard and people are excited, you can sense that. We’re eager as well, we can’t wait to start this new project, with new players, a new coach, bringing that energy to the stadium. We have to earn it, and we want to start tomorrow in order to make our way towards where we want to be in May.”

    The leader of the team
    “It has to be a natural thing, it should come from them organically. We’ve got communicative players whose drive is contagious, and they’ll be carving out a role for themselves in no time. That’s vital in helping everything feel more connected. When communication is good, helping a teammate helps yourself as well. It’s not a case of someone saying you’re a leader and you have to do it – it has to come naturally. Leadership isn’t imposed, it comes to the fore, and there can be more than one leader given what individuals can transmit to the rest of the group.”

    Refereeing
    “We’re starting the season now so we’ll see how things go. I hope we don’t have to discuss the referees too much, and I don’t want to start now.”

    Rodrygo
    “There are always rumours during summer, but he looks good to me, he’s part of my plans. I want every one of the players here to be feeling part of the team, doing their bit, and performing at 100%. That’s all I’m concerned with right now.”

    Controversy in Mallorca-Barcelona
    “I don’t think it’s up to me to make comments about things that happen in other games. I listened to what Jagoba Arrasate had to say and I think he explained it very well.”

    Mastantuono’s contribution
    “He could get game time, yes. He’ll bring us quality and energy, he’s highly committed. He’s got great drive from a defensive perspective – in the little time I’ve spent with him I can see that Argentine spirit, he’s a warrior, but he’s got quality too. He’s a combative player and he’s got a beautiful left foot, both from set-pieces and in the final pass. He’s got lovely technique and he’s very young. We have to guide him, but he’s already playing at a very decent level.”

    Will Brahim play?
    “He looks in good shape, I knew him already. I know what a difference he can make, he has great positional understanding, he can do unusual things, he links fantastically with his teammates. He’s amazing in tight spaces, strong off both feet, a brilliant finisher. He hasn’t surprised me because I already knew him very well, and if he’s in the squad it’s because he could play a part tomorrow.”

    Mastantuono’s favourite player
    “I think it’s logical for Messi to be his favourite player. He’s from Argentina and he’s left-footed, so it’s no surprise to me.”

    His memories of the fans
    “I have wonderful memories. I even came back here for a Champions League game playing for Bayern, and we had a fantastic relationship, I really felt the love from the crowd. I’m in a different role now, but I have high expectations, I’m motivated and can’t wait to feel that connection with the people once more. A long time has passed, but I’ve always felt it. Whatever happens, and whatever they feel, I’m delighted to be back.”

  • MacIntyre and Hatton qualify for Team Europe

    MacIntyre and Hatton qualify for Team Europe

    By Ryder Cup Europe On August 18, 2025 12:00 UTC

    Robert MacIntyre and Tyrrell Hatton have secured automatic qualification for Team Europe for the 2025 Ryder Cup, taking place at Bethpage Black, New York, from September 26–28.

    The pair join the already qualified Rory McIlroy, Justin Rose and Tommy Fleetwood as Luke Donald’s team takes shape for the 45th edition of the biennial contest between Europe and the United States.

    MacIntyre sealed his spot last night after finishing in second place behind World Number One Scottie Scheffler at the BMW Championship, the penultimate FedExCup Playoff event of the season on the PGA TOUR. The World Number Eight was also runner-up at the U.S. Open behind J.J. Spaun in June and a month later finished in a tie for seventh at The Open Championship at Royal Portrush.

    Hatton will make his fourth consecutive Ryder Cup appearance for Team Europe. Since the qualification period began last August, the Englishman has recorded two victories at the Alfred Dunhill Links Championship and Hero Dubai Desert Classic, in addition to a runner up finish at the Abu Dhabi HSBC Championship and a tied fourth finish at the U.S. Open in June.

    Captain Luke Donald said: “Bob has put in some big performances on both sides of the Atlantic this season, and that fine form combined with his experience from 2023 will be invaluable in New York.

    “Securing a fourth straight Ryder Cup place underlines what a consistent performer Tyrrell is, and we’ll once again welcome his passion and experience to Team Europe.”

    MacIntyre enjoyed a memorable debut for Team Europe in 2023, going undefeated as a rookie and earning two and a half points from three matches as Europe secured a 16½-11½ victory in Rome. He will now be aiming for a first away victory in New York in September.

    Hatton featured on winning sides in 2018 and 2023 – when he beat Brian Harman 3&2 in the Sunday single matches to stay undefeated for the week- and the 33-year-old will also be looking for a first away victory this year.

    The automatic qualification period for Team Europe ends this Sunday, August 24. The top six players on the European Rankings at the conclusion of the Betfred British Masters hosted by Sir Nick Faldo will secure their spots, with Donald then due to select his six Captain’s Picks on Monday September 1.

    Shane Lowry occupies the final automatic qualification spot, however Rasmus Højgaard, currently eighth in the Rankings, is teeing it up at The Belfry this week and would overtake the Irishman if he earns 13.7 points or more. Højgaard will need to finish in a tie for 29th (with one other player only) or better if he is to join McIlroy, MacIntyre, Fleetwood, Rose and Hatton in Donald’s team

  • Hubble telescope uncovers rare star born from cosmic collision: ‘A very different history from what we would have guessed’

    Hubble telescope uncovers rare star born from cosmic collision: ‘A very different history from what we would have guessed’

    Astronomers using the Hubble Space Telescope have discovered that a seemingly ordinary white dwarf star is actually the result of a dramatic stellar merger.

    This result, detailed in a new study led by Snehalata Sahu and Boris Gaensicke of the University of Warwick in the U.K., suggests that other “normal-looking” white dwarfs scattered throughout the universe could also have violent pasts.

    “It’s a discovery that underlines things may be different from what they appear to us at first glance,” Gaensicke, study co-author and a professor of physics at the University of Warwick who serves as the principal investigator of the Hubble program, said in a statement. “Until now, this appeared as a normal white dwarf, but Hubble’s ultraviolet vision revealed that it had a very different history from what we would have guessed.”

    A white dwarf merges with a red giant, creating a bow shock that strips its outer layers and exposes its carbon core. A new study reports that the white dwarf WD 0525+526 was likely formed through such a merger event, rather than through the normal life cycle of a single star. (Image credit: NASA, ESA, STScI, Ralf Crawford (STScI))

    The star, named WD 0525+526, is located about 128 light-years from Earth. Though it appeared rather standard at first glance through visible light, further observations using the Hubble telescope revealed telltale signs of a more turbulent origin, the new study reports.
