"William Wulf and Anita Jones have written a brief, tantalizing, and important article in Science: “Reflections on Cybersecurity”. They point the way out of a tangle of security problems (not all, of course) that costs billions of dollars in losses billions in countermeasures, and billions more in opportunity costs — some known and some not even imagined."

"Scientists have long suspected that Mars was once a wet place, and that water helped to shape the geography we see there today. Now, thanks to a study published in the Journal of Geophysical Research, we don’t have to simply imagine what a watery Mars might have looked like long ago—geographers have created this new map of the Red Planet covered in blue water."

"Physicists in the Netherlands are the first to show that spin-polarized electrons can be injected into silicon at room temperature. The team injected the electrons into both p-type and n-type silicon and measured how long the polarization lasted. Although the lifetime was shorter than expected the physicists believe it is long enough to support the development of spintronics devices."
