A study begun in Mexico with the collaboration of university students analysed the effect of weekend alcohol consumption on the lipids comprising cell membrane and its genetic material, i.e. DNA. Until now, the damage to the packaging of nuclear material in the early stages of alcohol abuse has never been documented, perhaps because most of the studies are done at later stages with people who have been consuming alcohol in an addictive way for many years. The results have been published in the journal Alcohol.

When you think of crocodiles, you usually envision them climbing trees.

Probably not. Most people imagine them in water or waddling on the ground, but a study has found that the reptiles can climb trees as far as the crowns. 

Vladimir Dinets, a research assistant professor in the Department of Psychology, says he is the first to thoroughly study the tree-climbing and basking behavior. 

The risk of a kidney donor developing kidney failure in their kidney is much lower than in the population at large, even when compared with people who have two kidneys, according to new Johns Hopkins research.

A recent analysis found that DietBet, a web-based commercial weight loss program that pairs financial incentives with social influence, delivers significant weight loss to participants.

On Dietbet.com, players join a game to lose weight while betting money on themselves. Players all have four weeks to lose four percent of their starting weight. At the end of week four, all players who have lost at least 4 percent of their initial body weight are deemed "winners" and split the pool of money collected at the start of the game.

To verify weight losses, players submit photo-based evidence of their weigh-ins to DietBet's referees at the start and end of each game.

The Affordable Care Act has a lot of costs and requirements that don't seem to make sense - requiring that plans include maternity coverage for post-menopausal women and single men comes to mind - and adding social workers into health care teams would seem to be another example of that.

Not so, said former Harvard Pilgrim Health Care CEO and current gubernatorial candidate Charles D. Baker Jr., keynote speaker at the Boston College Graduate School of Social Work Forum "Health Care Reform: From Policy to Practice", who believes that the social workers in his audience were going to bring an expansive view of care options under a "team-based care" approach.

Recent decades may have been the wettest in 3,500 years in North East Tibet – according to climate researchers at the University of East Anglia (UK) and the Chinese Academy of Sciences (Lanzhou, China).

Researchers looked at 3,500-year-long tree ring records from North East Tibet to estimate annual precipitation. They found that recent decades have likely been the wettest on record in this semi-arid region.

The precipitation records have been reconstructed using sub-fossil, archaeological and living juniper tree samples from the north-eastern Tibetan Plateau. They reveal a trend towards wider growth rings, implying moister growing conditions – with the last 50 years seeing increasing amounts of rainfall.
