That brings us back to these "modules." The LG G5 is the first phone of the year — and the first in a very, very long time — to attempt to augment functionality via optional accessories that clip into the bottom of the phone, using the same battery. It's becoming more apparent that Lenovo's Motorola phones are going to do something in that same vein. But this has been a mess from the start. There currently are two modules ("Friends," LG calls them) in existence. There's the LG CAM Plus camera grip and extended battery, and the Hi-Fi Plus with B&O Play high-definition digital-to-analog converter. Only, the Hi-Fi Plus isn't available to those of us who live in the United States. (LG has yet to officially explain why.) … [Read more...] about Simplicity, not modular mayhem, is what LG and Lenovo (and the rest of us) need

Had he even seen the Glassdoor article, Bicks asked? Was Schwartz really going to disavow an article about him, in his own e-mail, keyed to a Google Alert he had apparently set? The question was just one more chance for Schwartz to get in another zinger. … [Read more...] about Sun’s Jonathan Schwartz at trial: Java was free, Android had no licensing problem
Scientists could see that roughly 23,000 sections of the genome, made up of about 1,000 base pairs each, coded for proteins. In other words, these sections, called genes, were structured in such a way that cells could read them off to build protein molecules, which then performed cellular functions. But the genes made up less than 2 percent of the total human genome. What did the rest of the endless spirals of DNA base pairs mean? Many scientists thought most of it was useless gobbledygook left over from our evolutionary past. They called it "junk DNA."

But argon-argon dating is a very different technique from uranium-lead. It requires calibration to a reference material, and it involves irradiating samples in a nuclear reactor "There is a difference between argon-argon and uranium-lead [techniques]," says Burgess, :In some cases, it's 0.1-0.2 percent difference — we're talking about 60,000 years at the end of the Cretaceous. A 60,000-year inaccuracy on one of those dates means a hell of a lot for the biosphere. "In order to compare uranium-lead and argon-argon dates, and do it in a robust way, you've got to layer-on uncertainty to account for potential inaccuracy. This allows us to compare apples to oranges, in effect." … [Read more...] about What Really Killed the Dinosaurs?
The only large theropods found in that Wyoming formation are tyrannosaurs — Tyrannosaurus rex and Nanotyrannus lancensis, they said. (Nanotyrannus is a controversial species. Some paleontologists maintain it's a relative of T. rex, and others say it's a T. rex juvenile.) But, based on the presence of the Tyrannosaurus and Nanotyrannus fossils in the area, it's possible that these species left the gnaw marks on the bone, indicating that tyrannosaurs were cannibals, McLain said. … [Read more...] about Cannibal Tyrannosaurs: Proof May Be in a Gnawed Bone
