Scientists using the James Webb Space Telescope (JWST) have discovered the oldest known black hole in the universe.
Nestled within a glowing red galaxy, it dates back 13 billion years and provides a rare glimpse into the universe’s earliest moments.
The black hole and the galaxy it belongs to are called CAPERS-LRD-z9. It is part of a series of galaxies known as the Little Red Dots. Compared to other galaxies, they are tiny, and they emit red light.
Since 2022, scientists have been puzzled by the red spots. Observed in the distant realms of our universe, astronomers thought they were either a cluster of faraway stars or black holes at the center of different galaxies. The fact that they emit so much light suggested that they might be clusters of stars. However, they formed at such an early time that so many stars together was improbable.
“We started seeing these objects everywhere,” Anthony Taylor, co-author of the new study, told Science News. It is now generally accepted that the Little Red Dots are a new class of galaxy that formed in the early stages of the universe.
The team decided to focus the JWST on one in particular, which seemed to be the oldest. This was CAPERS-LRD-z9. It emitted a huge range of infrared wavelengths. Using spectroscopy to split the light, the team studied the wavelength characteristics, looking for the fingerprint of a black hole.
As fast-moving gas is sucked into black holes, it circles and creates a certain pattern of wavelengths of light. The gases moving toward us stretch into red wavelengths, while those moving away compress into blue wavelengths.
“There aren’t many other things that create this signature. And this galaxy has it!” exclaimed Taylor in a statement.
A few even more distant spots could potentially be older black holes, but researchers have yet to see the same spectroscopic signature from them. This means that, at the moment, this is the oldest black hole ever discovered. At 13.3 billion years old, it formed just 500 million years after the Big Bang — a blink of time in the scale of the universe.
“When looking for black holes, this is about as far back as you can practically go,” said Taylor. “We’re really pushing the boundaries of what current technology can detect.”
Though the galaxies are quite small, the black hole at the center of CAPERS-LRD-z9 is not. It is about 300 million times the mass of our Sun, and roughly 10 times more massive than Sagittarius A*, the black hole at the center of the Milky Way. Even more intriguingly, its mass might represent around half of its galaxy’s total stellar mass, a proportion far greater than in younger galaxies.
Studying CAPERS-LRD-z9 doesn’t just confirm the existence of a black hole. It gives astronomers a crucial testing ground to refine theories of early galaxy and black hole evolution.
“We only ever survey very tiny areas of the sky with the James Webb Space Telescope,” said co-author Steven Finkelstein, “So, if we find one thing, there’s got to be a lot more out there.”
A Lahore magistrate on Sunday dismissed the case against transgender persons allegedly organising an “objectionable” private party after police had arrested them earlier.
According to the court order, a copy of which is available with Dawn.com, the case was dismissed after “no incriminating material is available on record which connects the accused persons with the commission of alleged offences.
“Hence, the request of 10 days for physical remand of the accused persons is hereby turned down, and the accused persons present in the court are hereby discharged in this case.”
The order added that no private witness of the occurrence was associated during the raid, nor were any statements taken.
“Moreover, no permission for making a raid is attached with the file on a private place. Prima facie, it seems that the accused persons were included in the case on the basis of forged and concocted facts,” the order said.
Lawyer Haider Butt represented the accused in the case. He confirmed to Dawn.com that all the accused were released and the case was discharged against them.
According to the first information report (FIR) of the incident, a copy of which is available with Dawn.com, the Punjab government ordered the arrests after videos of the party, purportedly involving 50-60 individuals, including transgender persons, went viral on social media.
Fashion designer Maria B initially posted videos on her social media accounts, demanding action against “transgender activists” that she claimed featured in the clips, terming such gatherings “against the moral values of the country.”
Per the FIR, the footage, dated August 1, allegedly contained “explicit content, prompting public outcry and a swift response from law enforcement.”
The case was registered on behalf of the government at the Naseerabad police station against “a group of 50 to 60 transgender persons under sections 292 (sale of obscene material), 292-A (printing/advertising obscene matter), and 294 (obscene acts in public) of the Pakistan Penal Code, alongside Section 6 of the Sound System Act.”
Following the arrests, Deputy Inspector General of Police (Operations) Lahore, Faisal Kamran, had said, “Promoting obscenity under the guise of a party or photoshoot is a serious legal offence.”
He said that illegal and unethical acts will not be tolerated in any form. “All individuals involved in the incident will be brought to justice.”
Kamran added that the screening of the banned film Joyland, which features a transgender love affair, was also stopped in the city. “Strict action will be taken against any activity conflicting with Islam and the law.”
The movie was set to screen in Lahore today, nearly two years after it was barred from cinemas in Punjab. The long-awaited screening was said to take place at an alternative venue instead of a movie theatre.
Responding to the development, Islamabad-based transgender rights activist Nayyab Ali said in a post on X that individuals seen in the video were “not trans activists” and had “nothing to do with our movement.”
Ali also alleged that the video was shot at a private party and only went viral after Maria B posted it, saying, “If it’s fahashi (vulgarity), then who spread it to millions? Maria B did. That’s a crime itself.”
Meanwhile, human rights activists raised concerns over the potential misuse of morality laws on social media. “While obscenity laws exist, their vague wording often leads to arbitrary enforcement, disproportionately targeting marginalised communities,” said a legal expert, requesting anonymity.
The government authorities also vowed to expand the crackdown on “immoral activities” across the province.
Keith Andrews previously confirmed that late decisions would be made on the availability of Kelleher and German forward Kevin Schade.
The Republic of Ireland international goalkeeper is fit to make his debut for the club alongside fellow summer signing Antoni Milambo, with Schade being named on the bench.
Rico Henry will start a competitive fixture for the first time since the FA Cup third-round tie against Plymouth Argyle in January.
Limited to five substitute appearances last term, the left-back is also named in the starting XI for a top-flight fixture for the first time since September 2023, when he picked up a lengthy injury against Newcastle United.
Igor Thiago, who also saw his 2024/25 campaign severely impacted by injury, starts up front.
Jordan Henderson is named among the substitutes, with club-record signing Dango Ouattara not registered in time to travel to the City Ground.
Brentford: Kelleher; Kayode, Collins, van den Berg, Henry; Yarmoliuk, Jensen, Milambo; Carvalho, Thiago, Lewis-Potter
Subs not used: Valdimarsson, Ajer, Arthur, Hickey, Roerslev, Henderson, Onyeka, Schade, Peart-Harris
The Canadian government has forced flight attendants at Air Canada back to work less than 12 hours after they began striking and ordered binding arbitration over a dispute that has left more than 100,000 travellers stranded around the world during the peak summer travel season.
Since March, Canada’s largest airline and the union representing its flight attendants have been locked in an increasingly bitter dispute over what the union has described as “poverty wages” and unpaid labour. Flight attendants are not paid for any work before or after the plane takes off.
On Saturday, Canada’s federal jobs minister, Patty Hajdu, said it was clear the talks had reached an impasse and that the impact was being felt by Canadians and visitors across the country.
“The talks broke down,” said Hajdu as she told reporters that she had asked the Canada Industrial Relations Board to order an immediate end to the strike and to impose binding arbitration. “It is clear that the parties are not any closer to resolving some of the key issues that remain and they will need help with the arbitrator.”
She appeared to link her actions to the toll that US tariff increases had taken on the Canadian economy. “In a year in which Canadian families and businesses have already experienced too much disruption and uncertainty, this is not the time to add additional challenges and disruptions to their lives and our economy,” she said in a statement.
Hajdu’s power to halt the strike stems from a section of the Canada Labour Code, which gives the minister unilateral authority to end work stoppages in order to “maintain or secure industrial peace”. While the section was rarely used by previous governments, the Liberal government has invoked it several times in the past year, quelling strikes by workers at Canadian ports, the post office and railway companies, prompting analysts to voice concerns that the use of the clause may be undermining workers’ rights.
The union representing the flight attendants decried the Liberal government for stepping in within hours, accusing it of violating their right to take job action. Air Canada had reportedly previously requested that the government intervene to impose binding arbitration.
Wesley Lesosky, of the Canadian Union of Public Employees, said the government was giving “Air Canada exactly what they want – hours and hours of unpaid labour from underpaid flight attendants, while the company pulls in sky-high profits and extraordinary executive compensation”.
After issuing a strike notice earlier this week, flight attendants stopped work in the early hours of Saturday. Around the same time, Air Canada, which operates about 700 flights a day, said it would begin locking flight attendants out of airports.
According to the aviation analytics firm Cirium, the airline had cancelled 671 flights by Saturday afternoon, leaving some travellers stranded overseas and others scrambling to find alternatives during the busy summer travel season. About 130,000 customers a day could be affected by a disruption, according to the airline.
Air Canada said it was planning on restarting flights on Sunday evening but that some would have to be cancelled over the next seven to 10 days as the schedule stabilises and returns to normal. It had previously said it could take up to a week to resume full operations.
The airline said earlier it had offered its flight attendants “an increase of more than 38% on global compensation”, but the union said the figure failed to fully account for inflation. Air Canada also said it was willing to pay flight attendants 50% of their wage for work done before planes take off, leading the union to reply that its members should be fully compensated for their labour.
About 70% of the airline’s flight attendants are women, said Natasha Stea, a local union president and flight attendant. She questioned whether they were being treated fairly, given that Air Canada pilots, the vast majority of whom are men, received a significant raise last year.
“We are heartbroken for our passengers,” she told the Associated Press late last week. “Nobody wants to see Canadians stranded or anxious about their travel plans, but we cannot work for free.”
The ANT257PF is the world’s fastest gaming monitor, reaching the highest refresh rate we have ever seen on a TN panel and in general. The monitor will be launched at 7,999 Yuan.
A few monitor manufacturers recently broke the 600Hz refresh rate mark with their newest flagship TN gaming monitors, but Ant Esports (a brand under HKC) is the first one to go beyond 700Hz using TN. The company launched its flagship eSports gaming monitor in China, known as the ANT257PF (originally showcased at Computex), which is the world’s first 750Hz gaming monitor, equipped with a Fast TN panel.
We did see LG launching world’s fastest OLED gaming monitor this month, which can deliver up to 720Hz refresh rate at 1080p resolution. So, technically even though LG might be the first to cross 700Hz mark but the ANT257PF is surely the first-ever 750Hz gaming monitor. Up unitl now AOC and MSI have been among the few companies to unveil their 600Hz+ TN gaming monitors, but the ANT257PF is now the new benchmark.
As per IT Home, the gaming monitor will be auctioned on 19th August on JD Auction Channel but for regular purchase, the monitor will cost 7,999 Yuan, which is close to US$1,110. The monitor offers a 1080p resolution and a response time of 0.8ms GtG. Not necessarily the best in the industry, but still quite fast enough for competitive gamres. Perhaps reaching 750Hz will be a difficult thing but users with high-end gaming rigs can reach 700+ FPS in eSports titles like Counter-Strike 2 and Valorant.
ANT257PF brings a 24.5-inch screen size, which is sweet spot for many enthusiasts and while the monitor brings excellent fluidity for fast-paced gameplays, it also brings a wide color gamut and great color accuracy for vibrant and color-accurate visuals. We are seeing 95% DCI-P3 and 99% sRGB color spaces and color accuracy of Delta E< 2. Plus, it also has the VESA HDR 400 certification, which is going to increase visual fidelity noticeably.
Apart from 1080p@750Hz, the monitor can also output 1280×960 and 1024×768 resolutions with 750Hz refresh rate if that what some users prefer. For connectivity, the monitor comes with 2x HDMI 2.1 ports and a single DP 1.4 port, which even though will be sufficient but for 1080p@750Hz, DP 2.1 could have been much better as DP 1.4 interface won’t be able to display uncompressed visuals.
As of now, only official MSRP of 7,999 Yuan (US$1,114) has been announced but the availability is unknown.
Pep Guardiola has re-asserted the need for Manchester City to sell more players before the end of the summer transfer window, saying the current size of his squad is “not healthy”.
The Spaniard spoke after the Cityzens’ convincing 4–0 victory at Wolverhampton Wanderers on the opening weekend of the Premier League season. Erling Haaland was at the double, while new signings Tijjani Reijnders and Rayan Cherki were also on the scoresheet.
City haven’t quite splurged to the degree Liverpool have this summer, but they’ve nonetheless been active. In addition to Reijnders and Cherki, James Trafford, Rayan Aït-Nouri, Sverre Nypan and Marcus Bettinelli have also joined the club.
While there’s talk of Real Madrid superstar Rodrygo and Paris Saint-Germain goalkeeper Gianluigi Donnarumma potentially ending up at the Etihad before the start of September, City’s focus for the window will be on outgoings.
James McAtee, Yan Couto, Maximo Perrone, Kevin De Bruyne and Kyle Walker have already been sold permanently this summer. At the same time, Jack Grealish, Vitor Reis and Juma Bah have departed on loan.
On his bloated squad, Guardiola told reporters: “[It’s] too much — too many people. I like a deep squad to compete in all competitions, but I don’t want to leave players at home. It’s not healthy. You cannot create a good vibe or atmosphere to compete.
“Everyone has to feel they can play and help. The club has known it since last season, it’s not news, but the situation is what it is.
“In the next two weeks, people will talk with players and agents to find a solution,” he added.
Ederson and Savinho were left out of the matchday squad on Saturday amid rife transfer speculation, although Guardiola suggested the pair missed out for other reasons. Ederson has attracted interest from Turkey, while Tottenham Hotspur are working on a deal for Savinho. City aren’t pushing either player out, but they will let them go if they prefer a move elsewhere.
Nottingham Forest, having signed McAtee, are also trying to prise versatile defender Rico Lewis away from Manchester.
Someone posted details of a novel negative SEO attack that they said appeared to be a Core Web Vitals performance poisoning attack. Google’s John Mueller and Chrome’s Barry Pollard assisted in figuring out what was going on.
The person posted on Bluesky, tagging Google’s John Mueller and Rick Viscomi, the latter a DevRel Engineer at Google.
They posted:
“Hey we’re seeing a weird type of negative SEO attack that looks like core web vitals performance poisoning, seeing it on multiple sites where it seems like an intentional render delay is being injected, see attached screenshot.Seeing across multiple sites & source countries
..this data is pulled by webvitals-js. At first I thought dodgy AI crawler but the traffic pattern is from multiple countries hitting the same set of pages and forging the referrer in many cases”
The significance of the reference to “webvitals-js” is that the degraded Core Web Vitals data is from what’s hitting the server, actual performances scores recorded on the website itself, not the CrUX data, which we’ll discuss next.
The person making the post did not say if the “attack” had impacted search rankings, although that is unlikely, given that website performance is a weak ranking factor and less important than things like content relevance to user queries.
Google’s John Mueller responded, sharing his opinion that it’s unlikely to cause an issue, and tagging Chrome Web Performance Developer Advocate Barry Pollard (@tunetheweb) in his response.
Mueller said:
“I can’t imagine that this would cause issues, but maybe @tunetheweb.com has seen things like this or would be keen on taking a look.”
Barry Pollard wondered if it’s a bug in the web-vitals library and asked the original poster if it’s reflected in the CrUX data (Chrome User Experience Report), which is a record of actual user visits to websites.
The person who posted about the issue responded to Pollard’s question by answering that the CrUX report does not reflect the page speed issues.
They also stated that the website in question is experiencing a cache-bypass DoS (denial-of-service) attack, which is when an attacker sends a massive number of web page requests that bypass a CDN or a local cache, causing stress to server resources.
The method employed by a cache-bypass DoS attack is to bypass the cache (whether that’s a CDN or a local cache) in order to get the server to serve a web page (instead of a copy of it from the cache or CDN), thus slowing down the server.
The local web-vitals script is recording the performance degradation of those visits, but it is likely not registering with the CrUX data because that comes from actual Chrome browser users who have opted in to sharing their web performance data.
Judging by the limited information in the discussion, it appears that a DoS attack is slowing down server response times, which in turn is affecting page speed metrics on the server. The Chrome User Experience Report (CrUX) data is not reflecting the degraded response times, which could be because the CDN is handling the page requests for the users recorded in CrUX. There’s a remote chance that the CrUX data isn’t fresh enough to reflect recent events but it seems logical that users are getting cached versions of the web page and thus not experiencing degraded performance.
I think the bottom line is that CWV scores themselves will not have an effect on rankings. Given that actual users themselves will hit the cache layer if there’s a CDN, the DoS attack probably won’t have an effect on rankings in an indirect way either.
ISLAMABAD: The size of Pakistan’s mutual fund sector has surged almost seven times over the past six years, with assets under management rising from Rs578 billion in 2019 to Rs3.93 trillion by June 2025, fuelled by robust growth in both conventional and Shariah-based funds, latest figures from the Securities and Exchange Commission of Pakistan (SECP) show.
The News reported that conventional funds rose 5.2 times over the period to Rs2.206 trillion, while Shariah-compliant funds surged 6.7 times to Rs1.726 trillion, narrowing the market share gap. Shariah-compliant products now account for 44% of the industry, up from 39% in 2019, reflecting rising investor preference for Islamic finance.
After jumping from Rs2.70 trillion in June 2024 to Rs4.43 trillion in December 2024, mutual fund deposits fell by more than half a trillion rupees to Rs3.93 trillion in June 2025.
A senior official of the SECP attributed the sharp decline to the federal government’s announcement of an incremental tax of up to 16% on banks with an advance-to-deposit ratio below 50% as of Dec 31, 2024. “To meet the Advance-to-Deposit Ratio requirement, banks had to either expand lending or reduce deposits. To ease deposit pressure, they encouraged large clients to shift funds into mutual funds, temporarily boosting mutual fund assets. Once the ratio target was met, much of that money flowed back into the banking system after December 31,” the official said.
Decline was around 10%, from December to June 2025, though a substantial increase on a year-over-year basis, he added. The official said that the SECP has been holding focus group sessions with industry stakeholders to map the next phase of reforms.
Key priorities include the digital transformation of mutual funds, the introduction of exchange traded funds (ETFs), and launching infrastructure and ESG-based funds to tap sustainable investment demand.
The regulator also plans to revamp mutual fund distribution models, promote systematic investment plans (SIPs) for retail savers, and enhance financial inclusion, with a special focus on women investors. Additionally, reforms are on the table for prudential limits, governance, and transparency standards to safeguard investor interests.
Market analysts say the sector’s growth has been fuelled by a mix of low bank deposit returns, rising financial literacy, and regulatory support. However, they warn that sustaining momentum will require innovation, wider accessibility, and robust oversight. With mutual fund penetration still low compared to regional peers, the SECP’s reform agenda signals a push to deepen capital markets and channel more domestic savings into productive investments — a shift that could support Pakistan’s broader economic development goals.
Retail investors now hold 39.2% of Pakistan’s total Assets Under Management (AUMs) in 2025, up from 38% in 2019, while corporate investors’ share reduced to 61% against 62% in 2019.
The SECP data also shows that 56% of total AUMs are conventional, while 44% are Shariah-compliant. There are now 768,769 individual investors and 6,361 corporate investors in the market, showing widening retail participation in mutual funds and capital markets.
Tooth decay is the most common health condition in permanent teeth worldwide, and many adults feel it each time a sip of cold water stings.
A new study suggests toothpaste made from keratin could help protect teeth by guiding an enamel-like shield to form on worn surfaces, moving beyond patchwork fixes.
Lead author Sara Gamea and senior author Dr. Sherif Elsharkawy are based at King’s College London (KCL), in the Faculty of Dentistry, Oral and Craniofacial Sciences.
Keratin is a structural protein that is abundant in hair and wool, and it can be extracted and processed into films, hydrogels, and scaffolds for biomedical use.
The new work leans on biomineralization, the natural process by which tissues organize minerals such as hydroxyapatite crystals to gain hardness and resilience, a long-standing challenge for true enamel repair.
The team made water-based keratin films that self-assemble, then tested whether these templates could organize calcium and phosphate from saliva-like solutions into ordered, enamel-like minerals.
In lab models of early white spot lesions, the keratin infiltrated porous enamel and supported the growth of tightly integrated crystals that restored appearance and improved mechanical properties without drilling.
The authors describe two practical delivery forms, a daily toothpaste for broad use and a professional gel for targeted spots, and note that first consumer products could be feasible within two to three years if development proceeds smoothly.
Fluoride toothpastes reduce the risk of cavities compared with non-fluoride formulas, and higher concentrations show a dose-response in children and adolescents.
But fluoride alone cannot rebuild missing minerals where the surface has already opened up.
This is why dentists sometimes turn to resin infiltration, a plastic-based approach that can seal pores yet releases trace monomers and by-products with measurable cytotoxic potential in laboratory systems.
Composite restorations also carry failure risks over time, with secondary caries and fracture among the main reasons that drive replacement in long-term studies.
Even with promising lab results, market adoption will depend on whether keratin-based toothpaste can match the price and convenience of standard products.
Large-scale production from hair or wool waste will require streamlined collection, processing, and quality control systems to make it cost-effective for daily consumer use.
Public perception may also influence uptake. While some may welcome a natural, sustainable ingredient, others could hesitate at the idea of a dental product derived from hair.
Clear education campaigns and transparent sourcing will be important to build trust and encourage widespread acceptance.
Hair and wool are plentiful waste streams, and keratin extracted from them has been moving into wound dressings, tissue scaffolds, and drug delivery, a good match for circular, low-impact materials in healthcare.
“Keratin offers a transformative alternative to current dental treatments,” Gamea explained.
“Not only is it sustainably sourced from biological waste materials like hair and skin, it also eliminates the need for traditional plastic resins, commonly used in restorative dentistry, which are toxic and less durable.”
If the keratin platform can be manufactured consistently, it could reduce reliance on petroleum-derived resins for some indications, while better matching tooth color and light scatter for a subtler look.
Before keratin-based toothpaste can reach consumers, it must pass through regulatory review to ensure both safety and efficacy.
In the United States, the Food and Drug Administration (FDA) would likely require it to be evaluated as an over-the-counter drug or medical device, depending on claims and formulation, which involves rigorous preclinical data, human trials, and manufacturing quality checks.
Similar processes apply in the European Union, where approval would require conformity to Medical Device Regulation standards.
Toxicology assessments will need to confirm that keratin derived from hair or wool is free of harmful contaminants and does not trigger allergic reactions.
Long-term wear studies will also be important to ensure that mineral layers formed on the enamel remain stable and do not flake or stain.
These steps will help confirm that the product is not only innovative but also safe and reliable for daily use.
Keratin biomaterials already show encouraging biocompatibility in areas like wound healing and tissue engineering, which helps the case for oral use, though dental products will still need rigorous safety, wear, and flavor testing before approval.
If trials confirm durable protection and relief from sensitivity in real mouths, the first wave may target early lesions and post-whitening sensitivity, with daily toothpaste following as manufacturing scales.
The study is published in Advanced Healthcare Materials.
