Scientists from Hiroshima University have developed a new way to detect hidden changes in collagen, a protein that supports skin, before visible signs of aging like wrinkles appear. Their research shows that collagen’s internal structure can weaken early on, even when the skin looks healthy by normal methods.
Key Facts
Collagen is a protein that keeps skin strong and structured.
The study showed collagen can lose its internal order before it breaks down visibly.
Traditional imaging methods detect late-stage collagen damage but miss early changes.
Researchers used advanced imaging techniques to see both collagen amount and organization.
Skin tissue may look healthy while microscopic changes affecting collagen structure are already happening.
Detecting these early changes could lead to better prevention and personalized skin treatments.
The findings may also help in wound healing and medical material development.
The research was published in the journal ACS Nano on July 16.

The CEOs of Google DeepMind, OpenAI, and Anthropic agree that powerful new AI systems need rules and outside checks before release. They propose a shared framework for regulating AI to protect safety and national security without stopping innovation.
Key Facts
Demis Hassabis (Google DeepMind), Sam Altman (OpenAI), and Dario Amodei (Anthropic) all want regulations for advanced AI technologies.
They suggest independent testing of AI systems by outside groups rather than just self-checks by companies.
Their proposals include setting standards, certifications, and the ability to limit access to risky AI models.
They want a U.S.-led regulatory system with international influence instead of different rules across states or countries.
They recognize urgent concerns about AI creating dangers for national security, including cyberattacks and bioweapons.
They do not want a broad ban on AI, just controls on the few highly powerful models that pose big risks.
The three differ on who should have final regulatory power: a government agency like the FAA, an industry group overseen by the government like FINRA, or an international forum like the IAEA.
Smaller AI developers may face challenges complying with complex certification processes, which could favor large companies.

The UK regulator Ofcom is investigating TikTok to see if it properly protects children from harmful content by checking their ages accurately. Ofcom is concerned that TikTok’s current methods might be letting many children see dangerous things online, and the investigation could lead to fines or other penalties.
Key Facts
Ofcom is formally investigating TikTok over concerns about protecting children from harmful content.
TikTok uses age checks that involve users entering their birth date and technology that guesses age from other information.
Ofcom worries these methods may fail to correctly identify many children, exposing them to harmful content like self-harm, suicide, and pornography.
If TikTok is found not complying with the law, it could face fines up to £18 million or 10% of global revenue.
The UK government plans to introduce a social media ban for under-16s next year, increasing demands for effective age verification.
Ofcom also doubts other platforms’ age-checking methods and suggests they switch to more reliable approaches.
Research shows 1 in 10 teenagers aged 15-17 still use popular dating apps despite age checks.
Ofcom found many pornography sites in the UK have no age checks, and search engines often link to these sites without restrictions.

The UK media regulator Ofcom has started an investigation into TikTok to check if the app properly protects children and stops them from seeing harmful content. Ofcom is focusing on how TikTok guesses users' ages using technology and whether these methods are strong enough.
Key Facts
Ofcom is investigating TikTok's child safety measures after concerns were raised earlier this year.
The UK government plans to ban children under 16 from several social media platforms.
TikTok uses “age inference” technology to estimate a user’s age based on their behavior and video watching habits.
Ofcom doubts that age inference is reliable enough to prevent children from accessing inappropriate content.
Social media companies must use “highly effective” ways to check users’ ages according to UK rules.
TikTok says it enforces age-appropriate rules using expert advice and advanced tech.
TikTok claims it has spent billions on online safety since it started in the UK eight years ago.
Ofcom had previously criticized TikTok for not being safe enough for children in a report from May 2026.

Canadian psychologist Candice Odgers argues that banning social media for teenagers may not solve mental health problems and could make things worse. She believes that online risks come from adults, especially men, rather than social media itself, and says the focus should be on better understanding how young people use technology.
Key Facts
Candice Odgers is a psychologist who studies adolescent mental health and technology use.
Odgers says men are the biggest cause of harmful behavior online, like sextortion and spreading false information.
She gave her own children smartphones at age 11 and allowed her daughter to use Snapchat from that age.
Odgers disagrees with banning phones or social media for under-16s and is concerned those bans may backfire.
She studies how young people use phones by collecting data about their activity, sleep, and feelings with their permission.
Psychologist Jonathan Haidt believes avoiding social media helps protect kids’ mental health. His views have influenced parents and politicians to push for age restrictions.
Odgers argues there is limited evidence that social media causes a mental health crisis for teens.
She highlights improvements in today’s teenagers, such as lower pregnancy rates and less violence, compared to past generations.

A major Australian healthcare provider, Partnered Health, suffered a cyber-attack on June 23 that exposed sensitive patient information. This data, including medical records and personal details, could be sold on the dark web despite legal efforts to prevent its public release.
Key Facts
Partnered Health reported that 21 clinics in cities like Sydney, Melbourne, and Canberra were affected by the data breach.
Stolen information includes treatment details, consultation notes, referral letters, diagnostic results, Medicare numbers, private health insurance info, names, dates of birth, and addresses.
The company obtained a temporary court order to stop the data from being used or published publicly.
Experts warned that this order likely won’t stop the stolen information from being sold on hidden internet markets known as the dark web.
Medical records are very valuable to cybercriminals, selling for up to $250 per record, much more than general personal information.
Unlike financial data, medical records cannot be changed once stolen, increasing the risk to patients.
Previous cyber-attacks in Australia include a 2022 breach of Medibank that exposed 9.7 million customers’ details.
Specialists suggest better cybersecurity training, public awareness, and research are needed to prevent such attacks.
