"We discovered that benign cancer cells produce the PML molecule and display abundant PML bodies, keeping them in a dormant, senescent state. Malignant cancer cells either don’t make or fail to organize PML bodies, and thus proliferate uncontrollably"

Viking landers did detect organics on Mars
In 1976 the NASA Viking landers took samples of soil on Mars and tested them for signs of organic carbon. A reinterpretation of the results now suggests the samples did contain organic compounds, but the results were not understood because of the strong oxidation effects of perchlorate, a salt now known to be found in Martian soils.

Scientists discover a chemical signal in human tears
This undated handout photo provided by the journal Science shows a donor woman watching sad films in isolation, using a mirror to capture tears into a vial. If a crying woman’s red nose isn’t a big enough turnoff to a man, a surprising experiment found another reason: Tears of sadness may temporarily lower his testosterone level. (AP Photo/Science)

A pesky bacterial slime reveals its survival secrets
A Bacillus subtilis biofilm, the light-colored, slimy, bacterial coating on top, displays unprecedented liquid repellency as it beads up a drop of ethanol solution that has been placed on it. This remarkable ability offers both a completely new perspective on how biofilms can protect themselves from a wide range of biocides and introduces the first model natural system for broadly non-wetting materials.

"Yesterday the Chicago Tribune published my reaction to the four papers on the retrovirus XMRV published this week in the journal Retrovirology. I was quoted as saying ”These four papers are probably the beginning of the end of XMRV and CFS”. I wish to retract this statement and explain my reasons for doing so."

"This marks the first time a commercial company has successfully recovered a spacecraft reentering from low-Earth orbit. It is a feat performed by only six nations or government agencies: the United States, Russia, China, Japan, India, and the European Space Agency."
