Freezing single atoms to absolute zero with microwaves brings quantum technology closer

Physicists at the University of Sussex have found a way of using everyday technology found in kitchen microwaves and mobile telephones to bring quantum physics closer to helping solve enormous scientific problems that the most powerful of today’s supercomputers cannot even begin to embark upon. 320 more words

Digesting bread and pasta can release biologically active molecules

Biologically active molecules released by digesting bread and pasta can survive digestion and potentially pass through the gut lining, suggests new research. The study reveals the molecules released when real samples of bread and pasta are digested, providing new information for research into gluten sensitivity. 615 more words

Women's faces get redder at ovulation, but human eyes can't pick up on it

Previous studies have shown that men find female faces more attractive when the women are ovulating, but the visual clues that allow this are unclear.

Omega-3 supplements and antioxidants may help with preclinical Alzheimer's disease

Here’s more evidence that fish oil supplementation and antioxidants might be beneficial for at least some people facing Alzheimer’s disease. A new report describes the findings of a very small study in which people with mild clinical impairment, such as those in the very early stages of the disease, saw clearance of the hallmark amyloid-beta protein and reduced inflammation in neurological tissues. 376 more words
