Restrictive drug laws censor science, researchers say By Kate Kelland LONDON (Reuters) - The outlawing of drugs such as cannabis, magic mushrooms and other psychoactive substances amounts to scientific censorship and is hampering research into potentially important medicinal uses, leading scientists argued on Wednesday. Laws and international conventions dating back to the 1960s have set back research in key areas such as consciousness by decades, they argued in the journal Nature Reviews Neuroscience. ...

The reason for the season, some might think (and not illogically so), is that according to a natural cycle, the Earth has temporarily shifted closer to the sun and is sweltering in the extra heat.

For the past several years, scientists have debated whether the light is really there, and what it means. Now, researchers are petitioning the management team of NASA's Fermi Gamma-Ray Space Telescope, the observatory that saw the light, to change its observing strategy to determine once and for all whether the signal really exists.

The result is a harvest of human embryonic stem cells, the seemingly magic cells capable of morphing into any of the 200-plus kinds that make up a person. ...

Engineers believe a micrometeoroid hit a solar wing panel on the GOES-13 spacecraft on May 22, knocking it off balance and triggering its instruments to shut down, NOAA wrote on its website. A team of engineers determined the collision did not damage GOES-13's instruments or the satellite, and were able to return it to service, NOAA said. ...
