Anorexia nervosa and bulimia nervosa are psychological disorders characterized by extreme eating behavior and distorted body image – both have few proven effective treatments.

A new paper suggests that the altered function of neural circuitry contributes to restricted eating in anorexia and overeating in bulimia.

The study used functional MRI to test this neurocircuitry by measuring the brain response to sweet tastes in 28 women who had recovered from either anorexia or bulimia.
Relative to a cohort of 14 women who had never suffered from either disorder, those recovered from anorexia had significantly diminished, and those recovered from bulimia, significantly elevated responses to the taste of sucrose in the right anterior insula.

A new drought-protecting chemical shows potential for crop protection during periods of dry weather.
A research team led by Sean Cutler, a plant cell biologist at the University of California, Riverside, has found a new drought-protecting chemical that shows high potential for becoming a powerful tool for crop protection in the new world of extreme weather.

Named “quinabactin” by the researchers, the chemical mimics a naturally occurring stress hormone in plants that helps the plants cope with drought conditions.

Birds in the Yukon-Kuskokwim Delta of western Alaska have been discovered having low-pathogenic avian influenza viruses with Eurasian genes, supporting the hypothesis that the area is a potential point of entry for foreign animal diseases such as the more highly pathogenic H5N1 strain, according to U.S. Geological Survey scientists.

The 400-mile IndyCar race July 7th at Pocono Raceway will be the first open-wheeled event at the 2.5-mile, triangular-shaped track since 1989.

Pocono Raceway's triangular design, known as "The Tricky Triangle," makes it truly unique. Pocono is the America's only professional race circuit with three turns, three different radii and three variant degrees of banking.

The Solar Impulse airplane, brain-child airplane of Bertrand Piccard and André Borschberg (who co-piloted the entire journey) that can fly day and night without fuel or polluting emissions, has ended its cross-country journey in New York City. Solar Impulse is an unique adventure that seeks to put some emotion into solar power and also a flying laboratory to find innovative technological solutions for today’s solar challenges.

Barnacles are a major problem for both small boats and large ships because they accumulate on the hulls and can reduce the fuel economy of a vessel by up to 40 per cent. 

That means CO2 emissions rise accordingly.
