Bright points in sun's atmosphere mark patterns deep in its interior Posted: 17 Apr 2014 04:17 PM PDT Like a balloon bobbing along in the air while tied to a child's hand, a tracer has been found in the sun's atmosphere to help track the flow of material coursing underneath the sun's surface.

Vitamin B3 might have been made in space, delivered to Earth by meteorites Posted: 17 Apr 2014 04:17 PM PDT Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis. The result supports a theory that the origin of life may have been assisted by a supply of key molecules created in space and brought to Earth by comet and meteor impacts.

Our brains are hardwired for language Posted: 17 Apr 2014 04:16 PM PDT People blog, they don't lbog, and they schmooze, not mshooze. But why is this? Why are human languages so constrained? Can such restrictions unveil the basis of the uniquely human capacity for language? New research shows the brains of individual speakers are sensitive to language universals. Syllables that are frequent across languages are recognized more readily than infrequent syllables. Simply put, this study shows that language universals are hardwired in the human brain.

Gene variant increases risk of colorectal cancer from eating processed meat Posted: 17 Apr 2014 04:16 PM PDT A common genetic variant that affects one in three people appears to significantly increase the risk of colorectal cancer from the consumption of processed meat, according to a new study.

Air temperature influenced African glacial movements at height of last ice age Posted: 16 Apr 2014 11:33 AM PDT Changes in air temperature, not precipitation, drove the expansion and contraction of glaciers in Africa's Rwenzori Mountains at the height of the last ice age, according to research. The results -- along with a recent study that found air temperature also likely influenced the fluctuating size of South America's Quelccaya Ice Cap over the past millennium -- support many scientists' suspicions that today's tropical glaciers are rapidly shrinking primarily because of a warming climate rather than declining snowfall or other factors.
