Nanomagnetic computers are the ultimate in efficiency
Wired Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Computers that run on chips made from tiny magnets may be as energy-efficient as physics permits. According to new calculations, if nanomagnetic computers used any less energy, they'd violate the second law of thermodynamics. Such computers are still semi-theoretical, but they could someday be used in the deep oceans or even deep space, where energy is at a premium. Read the associated Physical Review Letters abstract.

Clumpiness of distant universe surprises astronomers
Wired Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The universe appears to be clumpier than astronomers expected, according to the largest galaxy survey to date. The extra clumps could call for a redesign of the standard model of cosmology, and maybe a new understanding of how gravity works. Read the associated APS Physics Viewpoint. More

Neutrinos caught 'shape shifting' in new way
New Scientist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Neutrinos have been caught spontaneously flip-flopping from one type to another in a way never previously seen. Further observations of this behavior may shed light on how matter came to dominate over antimatter in the universe. More

Black holes with a "kick"
Forbes    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Numerical relativity calculations continue to bear fruit for researchers exploiting the Sony Playstation 3. The Air Force Research Lab's CONDOR cluster of 1,760 Sony Playstation 3s has managed to examine the recoil effect that black holes would undergo when swallowing smaller main sequence stars like the sun. Read the associated Physical Review D abstract.

The Hole Picture: Growth of black holes and galaxies linked from an early age
Scientific American    Share    Share on FacebookTwitterShare on LinkedinE-mail article
It's the source of a long-standing cosmological quandary. Galaxies or black holes: Which came first? Today, they exist as neatly matched pairs, a black hole nested in the heart of a swirling galaxy, but it seems possible that the growth of one drove the growth of the other. More

Science of friction is a bit rough
Science News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
By playing with plastic blocks that stick and slip much like rock, physicists are challenging centuries-old ideas about the nature of friction itself. Seemingly unimportant differences at small scales can have big consequences, physicists report in an upcoming article in Physical Review Letters. Read the associated Physical Review Letters abstract.
