The last star to go supernova in the Milky Way—that astronomers know of—exploded in 1604, before Galileo first turned a telescope to the heavens. But with a neutrino detector now being built within a Japanese mountain that could come online as early as 2016, researchers might be able to do something as yet undone: Make detailed observations of a supernova in our galaxy before it visibly explodes. First, astronomers would be alerted to the unfolding event by the flood of neutrinos generated when a supernova collapses. Within minutes, they could determine the general area of the sky where the explosion would occur, point their infrared telescopes in that direction, and wait for the fireworks. With the new sensor in place, instruments—especially infrared telescopes—would have an almost 100% chance of observing the next supernova in our galaxy, the researchers report.

Cornell physicists say they've figured out why science works, or more specifically why scientific theories work – a meta theory. Publishing online in the journal Science Nov. 1the team has developed a unified computational framework they say exposes the hidden hierarchy of scientific theories by quantifying the degree to which predictions – like how a particular cellular mechanism might work under certain conditions, or how sound travels through space – depend on the detailed variables of a model.

AT&T has bought the U.S. retail wireless operations of Atlantic Tele-Network Inc. (ATNI) for $780 Million. Alltel operates under the Alltel brand in several markets. The acquisition includes wireless properties, licenses, network assets, retail stores, and about 585,000 subscribers. It also includes spectrum in the 700 MHz, 850 MHz, and 1900 MHz bands, and that's likely the big draw as the carrier continues to build out its 4G LTE network. If the deal is approved by the FCC and Justice Department, AT&T expects it to close in the second half of 2013.
