A tiny fossil tail offers the first “irrefutable” proof of a dropped tail

A 13-year study shows how sensitive deep-sea animals are to disturbance, scientists say

A common liver disease affecting nearly 30% of adults worldwide may be far more complicated than scientists previously realized. Mayo Clinic researchers have discovered that fatty liver disease actually consists of five distinct biological subtypes, each carrying different risks for liver failure, cancer, heart disease, and other serious complications.

Researchers have identified striking parallels between Sigmund Freud’s century-old theories and modern neuroscience, suggesting that the brain’s constant predictions shape how we experience reality. The findings could help explain why harmful thought patterns are so difficult to break and offer new insights into treating mental disorders.

Eating too much salt may do more than raise blood pressure. It could also harm memory and social behavior. In a new study, Japanese researchers discovered that a soy-derived compound called LPC70 helped protect mice from several damaging effects of a high-salt diet. Mice given the supplement had lower blood pressure, better memory, and improved social interactions compared with mice consuming excess salt alone.
