Dinosaurs May Have Been Neither Warm-blooded Nor Cold-Blooded 54

Posted by Soulskill from the bbq-sauce-for-blood-like-americans dept.
An anonymous reader writes An article published in Science (abstract) points to the possibility that dinosaurs were mesotherms more akin to modern Tuna. Their internal temperature would have been warmer than their surrounding environment, conferring on them the ability to move more quickly than any ectotherm ("cold blooded" animal), but wouldn't have been constant or as warm as any endoderm ("warm blooded" animal). Their energy use and thus their necessary food intake would have been greater than an ectotherm, but much less than an endotherm. In order to arrive at this possibility, bone growth rings in fossilized bone were used to establish growth rates and then compared to modern ectotherms and endotherms.

Open-Source Hardware For Neuroscience 41

the_newsbeagle (2532562) writes "The equipment that neuroscientists use to record brain signals is plenty expensive, with a single system costing upward of $60,000. But it turns out that it's not too complicated to build your own, for the cost of about $3000. Two MIT grad students figured out how to do just that, and are distributing both manufactured systems and their designs through their website, Open Ephys. Their goal is to launch an open-source hardware movement in neuroscience, so researchers can spend less time worrying about the gear they need and more time doing experiments."

EU's Top Court May Define Obesity As a Disability 625

Posted by samzenpus from the can't-work-eating dept.
mrspoonsi (2955715) writes The EU's top court is considering a test case which could oblige employers to treat obesity as a disability. Denmark has asked the European Court of Justice to rule on the case of a male childminder who says he was sacked for being too fat. The court's final ruling will be binding across the EU. It is seen as especially significant because of rising obesity levels in Europe and elsewhere, including the US. If the judges decide it is a disability then employers could face new obligations. Employers might in future have a duty to create reserved car parking spaces for obese staff, or adjust the office furniture for them, she said.
