Inside naked mole rats' ability to endure long periods of oxygen deprivation | Creativity can increase attractiveness to others, study suggests | March for Science a life-changing experience for 3 organizers
The naked mole rat can endure low oxygen levels for hours and can even go completely without oxygen for up to 18 minutes, according to a study published in Science. The mammals convert fructose into fuel, which allows them to go into a sort of hibernation for a period without oxygen.
Exhibiting creativity may boost some people's attractiveness to others, a study published in Royal Society Open Science suggests. Participants were asked to rate the overall attractiveness of people when their photos were linked to a piece of creative writing, and researchers found that "creativity enhanced the appeal of both men and women with average-looking faces," said study author Christopher Watkins.
Organizing Saturday's March for Science has been a life-changing experience for the three young scientists behind the global movement that began in January. Caroline Weinberg, Jonathan Berman and Valorie Aquino have had to put their work aside as interest in the march swelled.
Electrical stimulation sent to the brain at certain times can boost memory, according to a new study published in Current Biology. Scientists found that sending a jolt when brain signals suggested a likely memory lapse helped the person's recall significantly, but a zap when signals indicated something would be recalled reduced the chance a person would remember it.
Phosphate mining in China is threatening a site rich in fossils dating back to about 600 million years ago, and paleontologists are fighting to preserve it. Already two other sites have been lost to mining, but scientists' efforts have temporarily stopped mining near the Doushantuo geological formation.
Macrophages are not just immune cells -- they also help the heart beat, according to a study published in Cell. Researchers looked at mice to find out what macrophages did in heart muscle cells and found that they provide an electrical boost that helps the heart contract and pump blood.
Adding pure oats without gluten contamination to a gluten-free diet does not appear to affect symptoms or biologic measures in celiac disease patients, researchers reported in the journal Gastroenterology. The review of 28 studies showed one year of pure oat consumption, in adults or children, did not affect histologic readings, intraepithelial lymphocyte counts or serologic tests.
Boston University School of Medicine researchers found that adults who drank one artificially sweetened soda daily were nearly three times as likely to develop dementia and ischemic stroke over 10 years, compared with those who didn't drink diet soda. The findings in the journal Stroke, based on data involving 4,372 adults ages 45 and older, also showed a 2.6 times increased odds of stroke but not dementia among those who drank six or fewer diet sodas a week.
