Scientists studying crops irrigated with treated wastewater discovered that trace pharmaceuticals often collect in plant leaves. Tomatoes, carrots, and lettuce absorbed medications such as antidepressants and seizure drugs during the experiment. ...

The asteroid impact that wiped out the dinosaurs didn't keep life down for long. New research shows that microscopic plankton began evolving into new species within just a few thousand years--and possibly in under 2,000 years--after the disaster. ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and partially break apart to bind key DNA sequences that .. ...

Spiders and insects may not be fan favorites, but they are vital to the health of ecosystems--and scientists barely know how they're doing. Researchers found that nearly 90% of North America's insect and arachnid species have no conservation status, ...

Hair may grow in a completely different way than scientists once believed. Instead of being pushed out from the root, new research shows that moving cells inside the follicle actually pull the hair upward like a microscopic motor. Advanced 3D imaging ...

Scientists may have finally solved the mystery of strange plume-like structures hidden deep inside the Greenland ice sheet. New research suggests they form through thermal convection--slow, swirling motions driven by temperature differences inside .. ...

Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million regulatory DNA sequences that act like genetic .. ...

A newly identified Australian tree has been dubbed the "zombie" tree because it's alive but unable to reproduce. Myrtle rust repeatedly kills its young growth, stopping the species from flowering or making seeds. Scientists are scrambling to grow ...

Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found to spread across moist surfaces by fermenting ...

A study from Kobe University has uncovered a surprising partnership between Japanese red elder plants and Heterhelus beetles. The beetles pollinate the flowers but also lay eggs inside the developing fruit. The plant responds by dropping many of ...
