Low fat diet is key to a slimmer figure, study suggests Posted: 06 Dec 2012 05:32 PM PST Exchanging fatty foods for lower fat alternatives will help people shift around three-and-a-half pounds -- without any other form of dieting. People taking part in trials also saw their waist-lines become slimmer, and levels of bad cholesterol decrease. The results demonstrate that weight loss can happen without actively trying to lose weight beyond simply choosing foods lower in fat.

Deception can be perfected: Can a repeated lie become 'a truth? ' Posted: 06 Dec 2012 11:20 AM PST With a little practice, one could learn to tell a lie that may be indistinguishable from the truth. New research shows that lying is more malleable than previously thought, and with a certain amount of training and instruction, the art of deception can be perfected. Researchers found instruction alone significantly reduced reaction times associated with participants' deceptive responses. This research could have implications for law enforcement and the administering of lie detector tests.

Study of social network 'check-ins' shows we still make friends face-to-face Posted: 06 Dec 2012 11:13 AM PST Even in the age of social media, the closer you live to another persons, the more likely you are to be friends with them, according to a study that drew on data from a location-based social network provider.

Eating fewer, larger meals may prove healthier for obese women Posted: 06 Dec 2012 10:18 AM PST Media articles and nutritionists alike have perpetuated the idea that for healthy metabolisms individuals should consume small meals multiple times a day. However, new research suggests all-day snacking might not be as beneficial as previously thought, especially for obese women.

Fit kids finish first in the classroom Posted: 06 Dec 2012 10:18 AM PST Fit kids aren't only first picked for kickball. New research shows middle school students in the best physical shape outscore their classmates on standardized tests and take home better report cards.

Feeling disgust may enhance our ability to detect impurities Posted: 06 Dec 2012 09:23 AM PST From an evolutionary standpoint, experiencing the intense, visceral sense of revulsion that comes with disgust presumably helps us to avoid contaminants that can make us sick or even kill us. But new research suggests that disgust not only helps us to avoid impurities, it may also make us better able to see them.

New evidence for epigenetic effects of diet on healthy aging Posted: 06 Dec 2012 09:22 AM PST New research in human volunteers has shown that molecular changes to our genes, known as epigenetic marks, are driven mainly by aging but are also affected by what we eat. The study showed that whilst age had the biggest effects on these molecular changes, selenium and vitamin D status reduced their accumulation, and high blood folate and obesity increased them. These findings support the idea that healthy aging is affected by what we eat.

Protein linking exercise to bigger, stronger muscles discovered; Finding might lead to new therapies for muscle-wasting diseases Posted: 06 Dec 2012 09:17 AM PST Scientists have isolated a previously unknown protein in muscles that spurs their growth and increased power following resistance exercise. They suggest that artificially raising the protein's levels might someday help prevent muscle loss caused by cancer, prolonged inactivity in hospital patients, and aging.

Bisphenol A: BPA additive blocks cell function Posted: 06 Dec 2012 06:43 AM PST Bisphenol A, a substance found in many synthetic products, is considered to be harmful, particularly, for fetuses and babies. Researchers have now shown in experiments on cells from human and mouse tissue that this environmental chemical blocks calcium channels in cell membranes. Similar effects are elicited by drugs used to treat high blood pressure and cardiac arrhythmia.

'Sticky' stomach flu virus stands up to typical restaurant dishwashing measures Posted: 05 Dec 2012 04:58 PM PST Restaurant dishes and silverware may be an overlooked place where people can catch stomach viruses. While the current industry guidelines for cleaning dishware used in public settings are effective at neutralizing bacteria, researchers found that they appear to fall short of eliminating norovirus - the leading cause of epidemic gastroenteritis and the major cause of foodborne illness worldwide, responsible for at least 50% of all gastroenteritis outbreaks in the United States.
