Whale-eating sea monster uncovered in Peru Leviathan melvillei chomps down on a baleen whale. HIT PLAY, above, the see its fossilised teeth. Three lower teeth (a,b,c) of Leviathan melvillei compared to teeth of the modern sperm whale Physeter macrocephalus (d) and the modern killer whale Orcinus orca (e). BRISBANE: A 12-million-year-old giant sperm whale, which was was one of the biggest raptorial predators of all time, has been discovered in Peru, researchers said. The now-extinct species had teeth up to 36 centimetres long and 12 centimetres across, and has one of the biggest bites ever discovered in vertebrates, according to a report today in the journal Nature. “This sperm whale could firmly hold large prey with its interlocking teeth, inflict deep wounds and tear large pieces from the body of the victim,” said lead author Olivier Lambert, a palaeontologist at the Royal Belgian Institute of Natural Sciences in Brussels, Belgium. Giant whale had three metre skull Giant Moby Dick ate other whales

A Guide to the Orders of Trilobites welcome - library.nu Strange Science: The Rocky Road to Modern Paleontology and Biology Berkeley Explains Exactly Why It Chose Google Over Microsoft Wikimedia Commons and Google The University of California at Berkeley just decided to move off its old email system. It chose Gmail over Microsoft's Office 365. Usually, the decision-making process that goes into such a choice is shrouded in secrecy. In basic terms, Cal decided it could get Google Apps up and running faster and for less money. Particularly interesting: to move to Office 365, the university would have had to do a double migration -- first to an on-premise version of Exchange, then to the online version in Office 365. Here's where Google had the biggest advantages. Cheaper support during the migration. The solutions were pretty close in other areas, like delegated administration (neither was great, but Google was slightly better), user familiarity (it depends on what product people are using today), and mobile support. Microsoft won for authentication and the ability to integrate with on-premise systems.
DISCOVERING FOSSILS | Introducing the palaeontology of Great Britain The 48 Laws of Power Background Greene initially formulated some of the ideas in The 48 Laws of Power while working as a writer in Hollywood and concluding that today's power elite shared similar traits with powerful figures throughout history. In 1995, Greene worked as a writer at Fabrica, an art and media school, and met a book packager named Joost Elffers. Greene pitched a book about power to Elffers and six months later, Elffers requested that Greene write a treatment. Although Greene was unhappy in his current job, he was comfortable and saw the time needed to write a proper book proposal as too risky. However, at the time Greene was rereading his favorite biography about Julius Caesar and took inspiration from Caesar's decision to cross the Rubicon River and fight Pompey, thus inciting the Great Roman Civil War. Greene would follow Caesar's example and write the treatment, which later became The 48 Laws of Power. He would note this as the turning point of his life.
Image of the Day: The Oldest Supernova Explosion Ever Detected Astronomers have discovered the oldest and farthest supernova ever detected -- a massive star that exploded 11 billion years ago. Scientists compared several years of images taken from one portion of the sky, which let them look for objects that changed in brightness over time -- “subtracting” the changes from the original image –- which erased the entire galaxy save for the supernova, which had changed. “What we’re looking for are things that were there one year, but which weren’t there the next,” said Mark Sullivan, an astronomer from the University of Oxford in the UK and one of the authors of the study, in a separate BBC report. Prior to this discovery, NASA’s Swift Observatory had detected a 13-billion-year-old gamma-ray burst, most likely from a supernova near the beginning of the Universe.

"Time Crystals" Could Be a Legitimate Form of Perpetual Motion The phrases "perpetual-motion machine"—a concept derided by scientists since the mid-19th century—and "physics Nobel laureate Frank Wilczek" wouldn't seem to belong in the same sentence. But if Wilczek's latest ideas on symmetry and the nature of time are correct, they would suggest the existence of a bona fide perpetual-motion machine— albeit one from which energy could never be extracted. He proposes that matter could form a "time crystal," whose structure would repeat periodically, as with an ordinary crystal, but in time rather than in space. Wilczek describes his work in this article and in this one coauthored by Alfred Shapere of the University of Kentucky, that he posted on the physics preprint server, arXiv.org, on February 12. "The papers themselves are perfectly respectable, undoubtedly correct, and interesting," says cosmologist Sean Carroll of the California Institute of Technology. He and Shapere showed that a material could have zero total energy yet still be in motion.
BBC Nature - Pliosaurs videos, news and facts Second Wind: Air-Breathing Lithium Batteries Promise Recharge-Free Long-Range Driving--If the Bugs Can Be Worked Out Researchers predict a new type of lithium battery under development could give an electric car enough juice to travel a whopping 800 kilometers before it needs to be plugged in again—about 10 times the energy that today's lithium ion batteries supply. It is a tantalizing prospect—a lighter, longer-lasting, air-breathing power source for the next generation of vehicles—if only someone could build a working model. Several roadblocks stand between these lithium–air batteries and the open road, however, primarily in finding electrodes and electrolytes that are stable enough for rechargeable battery chemistry. IBM plans to take lithium–air batteries out of neutral by building a working prototype by the end of next year. Most fully charged lithium ion car batteries today will take an electric vehicle only 160 kilometers before petering out. Although this works in a computer simulation, lithium–air batteries have specific requirements in practice that scientists are still trying to meet.
Resurrecting the Woolly Mammoth? Scientists Plan to Clone the Extinct Creature Good news for anyone who wishes we could revert to prehistoric times, or really, anyone who thinks woolly mammoths are awesome. Scientists in Asia have announced plans to recreate the giant creature that stomped around the Earth some 4,500 years ago. On Tuesday, scientist Hwang Woo-suk of South Korea’s Sooam Biotech Research Foundation signed an agreement with Vasily Vasiliev of Russia’s North-Eastern Federal University to clone a mammoth, AFP reports. (MORE: Japanese Scientist Says We’ll Have Mammoths by 2015) Hwang, once lauded as a pioneer in the field of cloning, lost a bit of credibility in 2006 when some of his breakthrough human stem cell research turned out to be fabricated. However, experts have verified his work in creating the world’s first cloned dog, Snuppy, in 2005. So how exactly does one go about cloning a woolly mammoth? MORE: Free Woolly Out of the Cold
Strategies for Global Connectedness Not that long ago, the world was supposed to be flat. Hardly a day passed without references to globalization and “borderless markets.” Many policymakers and business leaders jumped on the bandwagon, treating all interconnection among countries as equally beneficial. But this perception that “the world is flat” was so exaggerated that it is fair to call it “globaloney.” In plotting a course toward smarter integration, the differences among countries matter a great deal. The other important dimension of global connectedness is breadth, which is the extent to which a country’s international trade flows are spread out globally versus confined to a particular set of partner nations. Connectedness and Growth An accurate read of the potential value of globalization for your particular country is the first step. The 2012 DHL Global Connectedness Index covered data through 2011 for 140 countries, accounting for 99 percent of the world’s GDP and 95 percent of its population.
