Well, "freezing" is not a temperature, merely a convenient local designation. Or so the newly discovered planet would seem to prove.

Submission + - The search for dark matter and dark energy
mlimber writes: The New York Times Magazine has a lengthy, popular article on dark matter and dark energy, discussing the past, present, and future:
'Astronomers now realize that dark matter probably involves matter that is nonbaryonic ["meaning that it doesn't consist of the protons and neutrons of 'normal' matter"]. And whatever it is that dark energy involves, we know it's not "normal," either. In that case, maybe this next round of evidence will have to be not only beyond anything we know but also beyond anything we know how to know.'
Drug Selectively Removes Rats' Memory 64
rednuhter writes "Nature online is reporting scientists have used drugs to selectively remove one memory while not affecting another.
Musical tones were played to the rats and at the same time the subjects were given a mild electric shock. Half the study group were given the drug (not approved for use in humans) and then the experiment was repeated with a new tone. The following day the rats that had not been given the treatment were afraid of both tones while the treated half were only afraid of the second tone: the memory of fear of the first had been erased."
NASA's Instrument For Detecting Life On Mars 88
Roland Piquepaille writes "With the financial help of NASA, American and European researchers have developed a new sensor to check for life on Mars. It should also be able to determine if traces of life's molecular building blocks have been produced by anything that was once alive. The device has been tested in the Atacama Desert in Chile. It should be part of the science payload for the ExoMars rover planned for launch in 2013."
