When a bone break is too severe to heal on its own, surgeons often rely on grafts or rigid metal implants -- but both come with serious drawbacks. Now, researchers at ETH Zurich have created a jelly-like hydrogel that mimics the body's natural ...

Scientists have identified a crucial molecular switch that decides whether pancreatic cancer cells resist chemotherapy or respond to it. The key player, a gene called GATA6, keeps tumours in a more structured and treatable form--but it gets shut down ...

For decades, scientists have mapped attention, memory, language, and reasoning to separate brain networks -- yet one big mystery remained: why does the mind feel like a single, unified system? Researchers at the University of Notre Dame now suggest . ...

Surviving cancer at a young age may come with an unexpected cost: faster aging at both the cellular and brain levels. Researchers found that survivors often show signs of being biologically older than their actual age, with chemotherapy accelerating ...

Researchers are developing a two-part therapy for type 1 diabetes: lab-made insulin-producing cells paired with custom-engineered immune cells that protect them. The goal is to stop the immune system from destroying transplanted cells -- without ...

As millions turn to ChatGPT and other AI chatbots for therapy-style advice, new research from Brown University raises a serious red flag: even when instructed to act like trained therapists, these systems routinely break core ethical standards of ...

A tiny wireless implant is giving new hope to people blinded by advanced age-related macular degeneration. In a major international clinical trial, more than 80% of participants regained meaningful central vision, with many able to read letters and . ...

Polyamines--natural molecules found in every living cell--have become stars in the longevity world for their ability to boost cellular cleanup and support healthy aging. But there's a dark twist: high levels of these same molecules are consistently . ...

Why do we tip--even when we know we'll never see the server again? New research suggests it's not just about rewarding good service, but about social pressure. Some people tip out of genuine appreciation, while others simply follow the norm. But here ...

Scientists have uncovered a powerful genetic switch that helps some of the body's most important immune cells grow up properly and keep our organs healthy. The switch, called MafB, guides immature precursor cells as they develop into macrophages, the ...
