Scientists have uncovered a surprising twist in how bacteria share genes--including those that spread antibiotic resistance. Tiny virus-like particles called gene transfer agents (GTAs), once ancient viral invaders, have been repurposed by bacteria . ...

The ozone layer has been on track to recover thanks to the Montreal Protocol--but a loophole may be holding it back. Chemicals still permitted for industrial use are leaking into the atmosphere at higher rates than expected. Scientists now estimate . ...

Scientists have discovered that methane in the open ocean is produced by microbes under nutrient-poor conditions, solving a long-standing mystery. As warming oceans reduce nutrient mixing, these methane-producing microbes may thrive. This could lead ...

A long-running dinosaur mystery may finally be solved: Nanotyrannus, once dismissed as just a teenage T. rex, appears to have been its own distinct species after all. Scientists analyzed a tiny throat bone from the original fossil and discovered ...

A badly mangled dinosaur skull, once forgotten in a drawer, turned out to be a rare and important discovery. Reconstructed by a Virginia Tech student, it revealed a new species of early carnivorous dinosaur with unusual features never seen before. .. ...

A massive, bus-sized "terror croc" that once preyed on dinosaurs has been brought back to life in stunning detail with the first scientifically accurate full skeleton of Deinosuchus schwimmeri. Stretching over 30 feet long, this ancient apex predator ...

Feeling mentally "on" isn't just in your head--it can significantly boost what you accomplish. Researchers found that sharper thinking on a given day leads people to set bigger goals and actually follow through. That edge can equal up to 40 extra ...

A new study proposes detecting life in space by spotting patterns across many planets instead of focusing on one at a time. If life spreads and changes planetary environments, it could leave behind statistical clues linking planets together. These .. ...

In a major breakthrough, scientists have observed electrons in graphene flowing like a nearly frictionless liquid, defying a core law of physics. This exotic quantum state not only reveals new fundamental behavior but could also unlock powerful ...

Scientists have taken a major step toward stopping Epstein-Barr virus (EBV), an extremely common infection linked to cancer and chronic disease. By using mice engineered with human antibody genes, researchers created powerful human-like antibodies .. ...
