Bacteria on Russian ‘sex satellite’ survive reentry

Guardian Science - Wed, 2014-11-19 20:23
Geckos used to study reproduction in space die in orbit, but thermophilic microbes still able to multiply after landing

A Russian “sex satellite” mission studying the cosmic reproduction of geckos, flies and bacteria has returned to Earth with the geckos dead but some of its bacteria still alive.

Two basalt discs with bacteria samples had been affixed to the outside of a Foton-M satellite that was launched into space by a Soyuz rocket in July. After almost six weeks in orbit 350 miles above the earth and a fiery reentry into the atmosphere, a strain of bacteria resistant to extreme heat was found alive in three of 24 indentations on the discs, a researcher from the mission announced at an astrobiology and aerospace medicine conference in Moscow on Wednesday.

Sun’s magnetic field sparks lightning on Earth

Guardian Science - Wed, 2014-11-19 18:14
Changes in the field could be used to forecast lightning in an area, alerting power companies and hill walkers to risks

Lightning is by its very nature unpredictable, but forecasting when and where it will strike has become easier following new research.

Space scientists have found that lightning strikes in the UK are being driven by changes that are occurring millions of miles away deep inside the sun. They found that the frequency of lightning strikes follows regular patterns that match the rotation of the sun’s magnetic field, increasing by up to 50% under certain circumstances.

Experiments on 18- to 42-year old men and women on active duty found that half an hour of electrical brain stimulation improved their performance twice as much as caffeine, and the effect lasted three times as long.
