First Peek into the Brain of a Freely Walking Fruit Fly

May 18, 2016 10:27 am | by University of California San Diego | News | Comments

Researchers have developed a technique for imaging brain activity in a freely walking fruit fly. Working with one of the most common model organisms in science, Drosophila melanogaster, the team shows for the first time what goes on in the brain of the fly during courtship -- when it's unrestrained.

Potential 'Fountain of Youth' Gene Found?

May 18, 2016 10:19 am | by University of Virginia | News | Comments

A gene that scientific dogma insists is inactive in adults actually plays a vital role in preventing the underlying cause of most heart attacks and strokes, researchers have determined. The discovery opens a new avenue for battling those deadly conditions, and it raises the tantalizing prospect that doctors could use the gene to prevent or delay at least some of the effects of aging.

Immunization with Bacteria Promotes Stress Resilience, Coping Behaviors in Mice

May 17, 2016 12:03 pm | by University of California San Diego | News | Comments

Injections of the soil bacterium Mycobacterium vaccae promote stress resilience and improve coping behaviors in mice, according to a new study. The researchers also found that M. vaccae prevented stress-induced colitis, a typical symptom of inflammatory bowel disease, suggesting that immunization with the bacteria may have wide-ranging health benefits.

New Approach to Sorting Cells

May 17, 2016 11:40 am | by Anne Trafton, MIT News Office | News | Comments

Microfluidic devices hold potential to rapidly analyze cells for applications in medicine and basic research. A team of researchers has now developed a new way to sort cells, based on their acoustic properties — that is, how they are affected by sound waves, which depends on how dense and compressible the cells are.

New Plant Stem Cell Discovery Points to Increased Yields

May 16, 2016 11:27 am | by Bevin Fletcher, Associate Editor | Articles | Comments

Researchers from Cold Spring Harbor Laboratory have discovered a new growth-regulating pathway in plants that has eluded scientists for years. In addition, by tweaking this new pathway the scientists have found a way to gently upregulate stem cell growth, boosting maize’s yield by up to 50 percent, which could have important real-world applications.
