What are the structural differences in the brain between animals that are self-aware (humans, apes) and other vertebrates? [More]

An international team of physicists has developed a method for taking ultrafast 'sonograms' that can track the structural changes that take place within solid materials in trillionth-of-a-second intervals as they go through an important physical process called a phase transition.

That might be a good thing. Here's why.

On that cool blue morning 10 years ago when everything changed, Les Robertson was half a world away, hosting a dinner at a Hong Kong restaurant. The rattling of cell phones left on the table--“a detestable habit”--was the first indication that something had struck one of the Twin Towers.

(PhysOrg.com) -- A high-temperature superconductor can now be switched on and off within a trillionth of a second – 100 years after the discovery of superconductivity and 25 years after the first high-temperature superconductor was. A team including physicists from the University of Oxford and the Max Planck Research Group for Structural Dynamics at the University of Hamburg has realised an ultrafast superconducting switch by using intense terahertz pulses.

A survey from PBS has revealed something pretty staggering for a $500-plus next-gen computing device: 70% of parents are happy to hand the iPad to their kids, and download child-friendly apps for the rugrats. A new PBS survey has 70% of parents reporting that they allow their kids to use their iPad

_ Plastics have a lot of issues--made from oil, they're often not recycled, and they end up in landfills. You might not consider soft, fluffy chicken feathers as problematic, but billions pounds of them end up in U.S.
