Scientists are raising concerns that we may be overlooking evidence of extraterrestrial life even when it is present. Hidden biosignatures, limitations in detection technology, and assumptions about what life should look like can all create dangerous ...

A new AI-powered framework could transform how astronomers measure the expansion of the Universe. By analyzing images of Type Ia supernovae and modeling their environments in unprecedented detail, researchers can estimate cosmic distances with near . ...

Researchers tested experimental PCAI compounds against pancreatic cancer cells and found they had powerful anticancer effects. One leading compound blocked more than 90% of cancer cell migration, suggesting it could help prevent the spread of tumors. ...

Fish oil supplements successfully delivered omega-3s to the brain, but a two-year study found no meaningful benefits for memory, cognition, or Alzheimer's-related brain changes. The results challenge the idea that fish oil pills can help prevent ...

Scientists have uncovered a surprising clue that may help explain why multiple sclerosis (MS) progresses rapidly in some people but not others. In brain tissue from patients with severe MS, researchers found large numbers of "foamy" immune cells ...

The unconscious brain appears to be far more capable than scientists once believed. Researchers found that patients under general anesthesia could still process language at a sophisticated level, distinguishing nouns, verbs, and adjectives while ...

Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils. Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots ...

A six-month study of more than 120 adults in their 70s found that high-intensity interval training (HIIT) may offer a key advantage over other forms of exercise: it helped reduce body fat while preserving valuable muscle mass. While moderate and low ...

Astronomers have finally cracked the mystery of the famous "Pink Planet," a strange world 57 light-years away that has puzzled scientists for more than a decade. Using the James Webb Space Telescope, researchers discovered that its atmosphere ...

Scientists at UCLA have linked long-term exposure to the pesticide chlorpyrifos with a sharply increased risk of Parkinson's disease. People exposed to the chemical near their homes were more than twice as likely to develop the condition. Laboratory ...
