11/17/11--11:06: The buzz around beer: Why do flies like beer? (chan 1642038)

Ever wondered why flies are attracted to beer? Entomologists have, and offer an explanation. They report that flies sense glycerol that yeasts make during fermentation. Specifically, they found that Gr64e, a receptor associated with neurons located in the fly's mouth-parts, is instrumental in signaling a good taste for beer. Once a fly has settled on beer, Gr64e detects glycerol and transmits this information to the fly's neurons, thus influencing the fly's behavior.

02/16/12--06:49: Organic food sweetener may be a hidden source of dietary arsenic (chan 1642038)

As people seek healthier dietary regimens they often turn to things labeled "organic." Lurking in the background, however, is an ingredient that may be a hidden source of arsenic -- an element known to be both toxic and potentially carcinogenic. Organic brown rice syrup has become a preferred alternative to using high fructose corn syrup as a sweetener in food. Unfortunately, organic brown rice syrup is not without its faults. Researchers have previously called attention to the potential for consuming harmful levels of arsenic via rice, and organic brown rice syrup may be the latest culprit on the scene.


02/16/12--08:04: Microbial oasis discovered beneath the Atacama Desert (chan 1642038)

02/21/12--09:50: Is fructose being blamed unfairly for obesity epidemic? (chan 1642038)

Is fructose being unfairly blamed for the obesity epidemic? Or do we just eat and drink too many calories? Researchers reviewed more than 40 published studies on whether the fructose molecule itself causes weight gain. In 31 "isocaloric" trials they reviewed, participants ate a similar number of calories, but one group ate pure fructose and the other ate non-fructose carbohydrates. The fructose group did not gain weight.
