Standing up gets groups more fired up for team work

Posted: 12 Jun 2014 08:46 AM PDT

Chairs provide great support during long meetings, but they may also be holding us back. Standing during meetings boosts the excitement around creative group processes and reduces people's tendency to defend their turf, according to a new study. The participants wore small sensors around their wrists to measure "physiological arousal" -- the way people's bodies react when they get excited. When a person's arousal system becomes activated, sweat glands around the feet and hands release bursts of moisture. The sensors pass a small current of electricity through the skin to measure these moisture bursts.

A picture's worth a thousand words: Using imaging to track beta cells, diabetes progression

Posted: 12 Jun 2014 06:51 AM PDT

A radiotracer or marker and PET scanning has been used by researchers as a non-invasive technique to follow changes in how many active beta cells a person has. For nearly 100 years, scientists have known that type 1 diabetes (T1D) is a disease fundamentally about the progressive loss of insulin-producing beta cells, but measuring that loss has continued to elude researchers -- at least until now.

Deepwater Horizon crude oil impairs swimming performance of juvenile mahi-mahi

Posted: 11 Jun 2014 10:21 AM PDT

Up to a 37 percent decrease in overall swimming performance of Deepwater Horizon oil-exposed juvenile mahi-mahi has been recorded by researchers. The findings reveal the toxic effects of crude oil on ecologically and commercially valuable fish that reside in the northern Gulf of Mexico. "What our study shows is that even a relatively brief, low-level exposure to oil harms the swimming capabilities of mahi-mahi, and likely other large pelagic fish, during the early life stages," said the lead author of the study.
