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-resistant bacteria and provide insight into ancient immune mechanisms shared with humans.

FDA-approved epilepsy drug may help reverse osteoarthritis damage

Researchers at Yale have identified a promising new approach to osteoarthritis that could do more than simply ease pain. The epilepsy drug lacosamide appears to block a protein involved in both pain signaling and cartilage destruction, helping damaged joints shift back toward rep

Scientists found Homo erectus 200,000 years earlier than expected

New fossils from South Africa are reshaping the story of early human evolution. Researchers have described 18 hominin fossils from Drimolen Cave, including an adult Homo erectus skull fragment dated to about 2 million years ago, supporting evidence that the species appeared in so

Stanford scientists turn a cancer driver into a kill switch

A Stanford-designed molecule turns a major lymphoma-promoting protein against cancer cells, activating their own self-destruct machinery instead of simply blocking tumor growth. In mice, the treatment completely eliminated aggressive human lymphoma tumors within 11 days, although

A new way to fight gum disease without wiping out good bacteria

Scientists discovered that disrupting the chemical messages bacteria use to communicate can push dental plaque toward a healthier microbial balance. The approach could lead to new treatments for gum disease that control harmful bacteria without destroying beneficial species.
