Submission + - HP unveils webOS tablet, plans webOS computer (itworld.com)

jfruhlinger writes: As had been expected, Hewlett-Packard unveiled new webOS-based smartphones and a webOS tablet today. But in a bit of a shock, the company also announced that webOS would be coming to HP PCs. Whether this is happening in specialized products only or HP plans a wholesale repudiation of Windows, it's definitely a bold move.

Submission + - New Theory Explains Periodic Mass Extinctions

i_like_spam writes: The theory that the dinosaurs were wiped out by an asteroid impact, the K-T extinction, is well known and supported by fossil and geological evidence. Asteroid impact theory does not apply to the other fluctuations in biodiversity, however, which follow an approximate 62 million-year cycle. As reported in Science news, a new theory seems to explain periodic mass extinctions. The new theory found that oscillations in the Sun relative to the plane of the Milky Way correlate with changes in biodiversity on Earth. The researchers suggest that an increase in the exposure of Earth to extragalatic cosmic rays causes mass extinctions. Here is the original paper describing the finding.

No - if you read the actual Science article you'll notice that they only used the loxP-LTR fusion as a starting poitn to evolve an enzyme they dubbed 'Tre' which can recognize HIV LTRs. They wind up demonstrating that it can excise HIV from a genome. Seriously, CRE recombination has been around for decades. If they had simply shown that CRE can excise an HIV genome flanked by lox sites, it wouldn't have been in Science.
