New fathers appear to have fewer mental health diagnoses during pregnancy and the early months after birth. But that early stability does not last. About a year later, depression and stress-related disorders increase significantly, surprising ...

A new neural implant is so small it can rest on a grain of salt, yet it can track and wirelessly transmit brain activity for over a year. It's powered by laser light that safely passes through tissue and communicates using tiny infrared signals. This ...

Scientists have found that your brain separates memories into "what" and "where/when" using two different groups of neurons. One set responds to specific objects or people, while another tracks the context or situation. When you remember something .. ...

Researchers have identified microRNA-93 as a key genetic driver of fatty liver disease and discovered that vitamin B3 can effectively shut it down. This finding suggests a safe, widely available vitamin could become a powerful new treatment.

Astronomers have finally cracked a decades-old mystery about red giant stars--how material from their deep interiors makes its way to the surface. Using cutting-edge supercomputer simulations, researchers discovered that stellar rotation plays a ...

Scientists have uncovered a new species of rhinoceros in the Canadian High Arctic, revealing that rhinos once lived far farther north than expected. The fossil, dating back 23 million years, is unusually complete and has helped reshape ideas about .. ...

A global team of leading scientists is zeroing in on a tiny but powerful molecule that could reshape how we age. Known as NAD, it plays a crucial role in keeping our cells energized, repairing DNA, and maintaining overall health--but its levels ...

For over a century, scientists have chased the dream of insulin pills, but the digestive system kept destroying the drug before it could work--forcing millions of patients to rely on daily injections. Now, researchers at Kumamoto University have ...

Scientists have turned simple glass into a powerful quantum communication device that could safeguard data against future quantum attacks. The chip combines stability, speed, and versatility--handling both ultra-secure encryption and record-breaking ...

Scientists have found a clever way to supercharge ultra-thin semiconductors by reshaping the space beneath them rather than altering the material itself. By placing a single-atom-thick layer of tungsten disulfide over tiny air cavities carved into a ...
