According to the European Monitoring Centre on Drugs and Drug Addiction, cocaine is the second most commonly used illegal addictive in Europe, after cannabis.  A discovery related to the mechanism behind a dopamine transporter could help in the development of future medical treatment against cocaine addiction.  

In space no one can hear you bleed, but what about on a private spacecraft? 

The commercial aviation industry has medical care standards, as does NASA for traditional space missions. Eventually someone is going to tell Elon Musk and Richard Brandon that the commercial space transportation industry will need to define medical care practices as well.

There are well-known risks, of course, but there can be disclaimers 400 pages long and if an attorney stands in front of a jury and talks about what lax safety standards there are, someone with the passionate pleading skill of John Edwards will get a judgment that runs their companies into bankruptcy.

If you want to make your children neurotic, clinginess and overprotectiveness on your part - helicopter parenting - is the way to go.

Assuming you don't want to cause that, it is still okay to hover over your dogs and cats, according to an analysis of pet owners by psychologists at U.C. Berkeley and California State University, East Bay.

For most people, they can extend their healthy lifespan by walking for 20 minutes a day. Yet most people don't do it.

It's become a popular sport to criticize obese people while lamenting that our pop culture encourages people to be too thin. We should be criticizing people who don't go for walks rather than fat people if we care about lowering health care costs, according to a study of over 334,000 European men and women which found that twice as many deaths may be attributable to lack of physical activity compared with the number of deaths attributable to obesity.

In the future, if we use money to fund basic research for solar and stop subsidizing existing technology that does not work very well, there will be no energy crisis. In the time it takes you to read this article, the sun will provide enough energy to power the planet for a year.

But that does not translate to everything.  An international group of scientists has noted once again that "renewable" is not synonymous with "unlimited."

The change in global sea level rise since the beginning of the 20th century has been significantly larger than previous estimates according to new estimates in a new paper.

The paper, co-authored by Carling Hay, a Harvard post-doctoral fellow in the Department of Earth and Planetary Sciences (EPS), and Eric Morrow, a recent PhD graduate, says that previous estimates of global sea-level rise from 1900-1990 had been over-estimated by as much as 30 percent.  

But it confirms previous estimates of sea-level change since 1990, and that suggests that the rate of sea-level change is increasing more quickly than previously believed.
