Smurfs connect with Planar Cell Polarity

See paper by Narimatsu et al. Cell. 2009 Apr 17;137(2):295-307. www.cell.com Planar cell polarity (PCP) regulates polarity across the plane of the tissue and plays key roles in organizing tissue shape and function. One example of such a tissue is the inner ear, shown here as a 3D reconstruction with stereocilia (red) and centered kinocilia (blue). In Smurf ubiquitin ligase mutant mice, the inner ear displays cells with altered planar orientation and disorganized packing. ... cell press ...

Amateur climatologists exposed (again) [The Island of Doubt]

Anyone who still thinks, fears or harbors even the tiniest suspicion that the stolen CRU emails offer evidence that climatologists are cooking their data must read Tim "Deltoid" Lambert's examination of one of the most widely cited examples of the alleged crimes.

Science 2.0 generally refers to new practices of scientists who post raw experimental results, nascent theories, claims of discovery and draft papers on the Web for others to see and comment on. Proponents say these "open access" practices make scientific progress more collaborative and therefore more productive. Critics say scientists who put preliminary findings online risk having others copy or exploit the work to gain credit or even patents. Despite pros and cons, Science 2.0 sites are beginning to proliferate; one notable example is the OpenWetWare project started by biological engineers at the Massachusetts Institute of Technology.

How to Fix Bricked G1G1 XO Laptops Automatically

I've been getting increasing numbers of requests from donors in the first OLPC Give 1 Get 1, many of whom are just getting around to opening their XOs, to have their laptops repaired.

Wanted: a XO heartbeat

As is now widely known, due to a manufacturing glitch the first few batches of OLPC XO-1s that were shipped to consumers had a faulty motherboard battery holder. This alone wouldn't be a problem, if only two other things hadn't happened at the same time:

The XO-1s were shipped with Open Firmware's security enabled. This caused them to have the same anti-theft protection as laptops deployed in the third world, without any of the benefits of a remote killswitch or trackingThe XO-1s had a version of OFW which would fail to boot when the clock was below a certain value

The above two issues combined with the manufacturing fault was a recipe for disaster. Owners who discovered this in the first 30 days were able to get a RMA and a working laptop, but OLPC lacked the resources to support those outside of this minimal warranty.
