Antibiotics give rise to new communities of harmful bacteria Posted: 23 Feb 2015 01:45 PM PST Most people have taken an antibiotic to treat a bacterial infection. Now researchers reveal that the way we often think about antibiotics -- as straightforward killing machines -- needs to be revised.

Brain activity shows infants are hardwired to link images, sounds as they learn to speak Posted: 23 Feb 2015 09:25 AM PST We are biologically predisposed to link images and sounds to create language, new research examining electrical brain activity in infants suggests. These findings reveal that sound symbolism allows 11-month-old infants to spontaneously bind the speech sound and the visual referent, and this spontaneous binding may provide infants an insight that spoken words refers to objects you can see in the world, an author explains.

Magnetic nanoparticles could stop blood clot-caused strokes Posted: 23 Feb 2015 09:24 AM PST By loading magnetic nanoparticles with drugs and dressing them in biochemical camouflage, researchers say they can destroy blood clots 100 to 1,000 times faster than a commonly used clot-busting technique.

La Niña-like conditions associated with 2,500-year-long shutdown of coral reef growth Posted: 23 Feb 2015 09:23 AM PST La Niña-like conditions in the Pacific Ocean off the coast of Panamá were closely associated with an abrupt shutdown in coral reef growth that lasted 2,500 years, scientists have found. The study suggests that future changes in climate similar to those in the study could cause coral reefs to collapse in the future.
