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. 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).

Education & Outreach: Curriculum Resources Curriculum Resources On this page we have compiled resources for educators to use in the classroom. The first section consists of modules developed at NESCent. "Other Curriculum Resources" includes a list of various resources ranging from single lessons, to books, to computer simulations. The "Audio and Video Lecture" section has links to single lectures, interviews, and science shows. Some are are audio only while others include video. The 48 Laws of Power Background[edit] 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.[5] In 1995, Greene worked as a writer at Fabrica, an art and media school, and met a book packager named Joost Elffers.[4][8] Greene pitched a book about power to Elffers and six months later, Elffers requested that Greene write a treatment.[4] 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.[10] 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.[10] Greene would follow Caesar's example and write the treatment, which later became The 48 Laws of Power.[10] He would note this as the turning point of his life.[10]

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.

MUSE - Natural Selection - Course Overview and Materials Unit Overview The Natural Selection unit described on this site was developed for use with 11th and 12th grade students. If implemented as described here it will require seven to nine weeks of daily 45 minute instructional periods. "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.

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.

Candy Dish Selection Overview: In this lesson students become unwitting subjects in a demonstration of natural selection. Students select candies from a bowl and have an opportunity to think about what traits brought about the “survival” of some candies. Lesson Concepts: Not every feature is an adaptation. Adaptations often persist in a population because they are in some way advantageous. Adaptations are preserved in a population by natural selection. Second Wind: Air-Breathing Lithium Batteries Promise Recharge-Free Long-Range Driving 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.

Introduction 1. INTRODUCTION A typical ichthyosaur looks like this (see note for derivation and pronunciation of "ichthyosaur", as well as its usage in this page). Yes, just like a fish. The strange thing is that they were not fish at all: they were reptiles like lizards, snakes, and crocodiles. You can easily tell this by looking at the skull and fins. A similar case is known for mammals too: think about dolphins and whales.

eogsummer_resources_2011 Evolution 2011: A Workshop for Educators Resources Contents Monday Science Standards 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.”

Imaging technology reveals intricate details of 49 million-year-old spider 18 May 2011 Scientists have used the latest computer-imaging technology to produce stunning three-dimensional pictures of a 49 million-year-old spider trapped inside an opaque piece of fossilized amber resin. University of Manchester researchers, working with colleagues in Germany, created the intricate images using X-ray computed tomography to study the remarkable spider, which can barely be seen under the microscope in the old and darkened amber.
