    Cerebellum may be site of creative spark

    Creative sparks may fly from the brain’s cerebellum. Activity in that part of the brain, once thought to be a plodding, steady workhorse, increased as people inside an fMRI scanner created Pictionary drawings, scientists report May 28 in Scientific Reports.

    While other scientists caution that the brain scan results lack the precision to say that cerebellum activity tracks...

    Fifty years ago, ethylene research ripened

    Fruits caused to ripen by volatile ethylene — Apples turn red, bananas turn yellow and honeydew an icy white because of the volatile substance, ethylene, present in the plant tissues. Recent studies using gas chromatography show that ethylene acts as a...

    Double blow to skull is earliest evidence of murder, a 430,000-year-old whodunit

    It’s a classic murder mystery: no motive, no weapon, no suspect. Just a body, dumped in a remote location with fatal head injuries. It would be standard fare for an episode of CSI — except that it happened 430,000 years ago. That makes it the earliest documented case of homicide, researchers report May 27 in PLOS ONE....

    Fossils suggest another hominid species lived near Lucy

    Here come the neighbors, Lucy. Scientists have discovered 3.5-million- to 3.3-million-year-old fossils possibly from a new species in the human evolutionary family. The species lived in what’s now Ethiopia, near hominids best known for Lucy’s partial skeleton.

    A partial upper jaw and two lower jaws, one recovered in two pieces, belonged to Australopithecus deyiremeda, says a...

    Everest could lose most of its ice by 2100

    Glaciers around the tallest mountain in the world may reach a historic new low relatively soon.

    Combining projections of future climate with simulations of how glaciers melt and grow, researchers estimate May 27 in The Cryosphere that the Everest region of the Himalayas could lose 73 to 96...

    Diet and nutrition is more complex than a simple sugar

    When it comes to studying the vast complexity of the food we eat, it helps to simplify. Test one nutrient or variable at a time to find out how each functions. Compare one part of a sugar molecule against another. These studies can tell us a great deal about how specific nutrients are processed in the body, and how they affect our health, our waistlines and even our behavior.

    But one...
