Neanderthals may have used a sticky substance made from birch bark to treat wounds thousands of years before antibiotics existed. Researchers recreated ancient birch tar production techniques and discovered that every sample could inhibit the growth ...

Scientists have developed a tiny, injectable device that can control nerve activity without surgery, batteries, or wires, potentially transforming treatment for chronic pain and movement disorders. Powered wirelessly from outside the body, the seed . ...

Princeton Plasma Physics Laboratory may have found a dramatically more efficient route to fusion energy by reversing the traditional approach: heating plasma first, then increasing its density. Their calculations could help future reactors reach self ...

A large study suggests loneliness and social isolation can cost people years of healthy life, especially when it comes to mental health. Men experiencing both lost about 5.8 years free from depression and anxiety, while women lost roughly 3.7 years.

Astronomers have discovered a bizarre star system about 300 light-years from Earth where a small star is slowly devouring a nearby brown dwarf, an object too massive to be a planet but too small to be a true star. Unlike stars that rapidly swallow .. ...

Scientists have developed a powerful new way to calculate the Kondo effect, a strange quantum phenomenon that appears when magnetic atoms are embedded in metals. Instead of relying on simplified models, the method uses the real atomic and electronic ...

A strange chemical signature in old Hubble observations may point to a planet that formed after its star had already died. Astronomers found unusually high levels of niobium around the white dwarf HS 0209+0832, suggesting some of the star's expelled ...

Scientists have uncovered a hidden world of "in-between" materials that briefly form as chemical ingredients are heated, revealing structures that conventional methods can miss. Among the discoveries is a previously unknown form of bismuth vanadate, ...

Researchers have uncovered a new way bacteria detect viral attacks: a virus-produced enzyme cuts a bacterial sensor protein, triggering a self-destructing immune response. The discovery could lead to more effective phage therapies against antibiotic ...

A Canadian radio telescope has detected the faint glow of hydrogen from billions of years ago using only its own observations, proving a long-awaited way to map the distant universe can actually work. CHIME can use this hydrogen signal to trace how . ...
