...rease in amyloid deposition that was more than the additive
effect of the two mutations. The researchers pointed out that test tube studies have shown that Ab42 aggregates more readily. "Thus, the simplest explanation for the complete lack of pathology in the [Ab40] mice would be the relative inability of Ab...
Aloe vera coating may prolong freshness, safety of fruits and vegetables
... future you could be eating the gel as a healthful additive
to your fruits and veggies. Researchers in Spain say they have developed a gel from the tropical plant that can be used as an edible coating to prolong the quality and safety of fresh produce. The gel, which does not appear to affect food taste or ap...
Green diesel: New process makes liquid transportation fuel from plants
...o sulfur-free liquid alkanes resulting in an ideal additive
for diesel transportation fuel. Co-researchers include chemical and biological engineering graduate students George Huber, Juben Chheda and Chris Barrett. "It's a very efficient process," says Huber. "The fuel produced contains 90 percent of the ene...
