Researchers have discovered a stunning new species of tiny orange-patterned fish in the Brazilian Amazon, but its survival may already be at risk. Named Laimosemion laranja, the brilliantly colored killifish measures less than three centimeters long ...

Scientists at UC San Francisco have developed a powerful new cancer therapy that remains inactive until it reaches the brain, where it switches on to attack deadly tumors. The engineered immune cells, called B-SYNC CAR-T cells, completely eliminated ...

A remarkable fossil discovery in Colombia is challenging how scientists understand major evolutionary changes in Earth's history. Researchers uncovered an incredibly diverse ancient marine ecosystem where giant reptiles, sharks, and other creatures . ...

More than a century after Einstein revolutionized our understanding of gravity, scientists have uncovered a surprising new phenomenon hidden within his equations. Researchers at Columbia University and Universidad Adolfo Ibáñez have identified a .. ...

Scientists have discovered that fasting for just 24 hours increases a beneficial gut bacterium that helps the intestines regenerate after radiation damage. The preclinical findings could pave the way for new treatments that protect healthy tissue ...

MIT scientists have developed nanoparticles that reprogram immune cells directly inside the body to attack cancer and harmful immune cells, eliminating tumors and reversing liver damage in mouse experiments. The breakthrough could make powerful ...

A nuclear explosion might save Earth from a deadly asteroid, but new research suggests that hitting the wrong side could make the difference between success and disaster. Scientists found that an asteroid's irregular shape can dramatically affect how ...

A major international study tracking more than 26,000 men found that very low testosterone levels were associated with an 18% higher risk of dying from cancer later in life. Surprisingly, testosterone itself showed no clear link to prostate cancer, . ...

Scientists investigating a 2,800-year-old Siberian tomb discovered roughly 1,000 cannabis seeds and chemical evidence suggesting ancient Scythians used the plant for its intoxicating effects. The remarkable find, surrounded by evidence of elaborate . ...
