Lost fossil sheds light on evolution of frightening fish
NASA, ESA to shut down Ulysses solar spacecraft after nearly 2 decades
Stress is known to decrease fertility and sexual behavior, but researchers thought this was because stress hormones lower levels of a brain hormone called gonadotropin releasing hormone, or GnRH. Biologists now show that stress hormones also boost levels of a hormone that suppresses GnRH — a double whammy. The scientists hope it will be possible [...]

For the first time, scientists in Germany successfully used an offshore observing system to study environmental changes in the oceans. The so-called mesocosms resemble oversized test tubes with a length of 20 metres. They are used to simulate the future ocean in situ, i.e. under realistic conditions.
Frequent binge drinking — having six or more alcoholic drinks at one occasion, at lease once a week — by Korean men was associated with a dramatic increase in hemorrhagic stroke. It is unclear whether the results can be generalized to other populations.
