Neanderthals "Had Sex" With Modern Man

According to Professor Svante Paabo, director of genetics at the Max Planck Institute for Evolutionary Anthropology, Neanderthals and modern humans had sex across the species barrier. The professor has been using DNA retrieved from fossils to piece together the entire Neanderthal genome, and plans on publishing his findings soon. He recently told a conference that he was sure the two species had had sex, but still had questions as to how "productive" the relations had been. "What I'm really interested in is, did we have children back then and did those children contribute to our variation today?" he said. "I'm sure that they had sex, but did it give offspring that contributed to us? We will be able to answer quite rigorously with the new [Neanderthal genome] sequence." What remains a mystery is what Paleolithic brewery provided the catalyst for these stone age hook-ups.

Engadget: Terahertz radiation and metamaterials combine to form super X-Ray specs

It looks like somebody actually coughed up the extra dollar for the De Luxe model X-Ray specs in the back of Mad Magazine, then reverse-engineered 'em in the name of science. That somebody is Richard Averitt, whose team at Boston University has come up with a way to use metamaterials and terahertz transmissions to see through you. We've seen metamaterials plenty of times before, typically being used for nefarious deeds on the opposite end of the spectrum: invisibility cloaks. Here they form pixels for a digital imager that can be activated by THz radiation. If you're not familiar with THz radiation, it's a (supposedly perfectly safe) form of energy waves that pass through materials -- much like X-Rays but without all the nasty DNA-shattering effects on the way through. There's just one problem: nobody (not even this guy) has made a powerful enough THz emitter just yet, meaning we're all safely naked under our clothes for at least another few years.
