YouTube - The Known Universe by AMNH - 0 views

  •  
    The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

YouTube - The Secret Life of Chaos-(BBC 2010)-Full Length Documentary - 1 views

  •  
    In this documentary, Professor Jim Al-Khalili sets out to uncover one of the great mysteries of science - how does a universe that starts off as dust end up with intelligent life? How does order emerge from disorder? It's a mind bending, counter intuitive and for many people a deeply troubling idea. But Professor Al-Khalili reveals the science behind much of beauty and structure in the natural world and discovers that far from it being magic or an act of God, it is in fact an intrinsic part of the laws of physics. Amazingly, it turns out that the mathematics of chaos can explain how and why the universe creates exquisite order and pattern.

YouTube - Bill Nye - Greatest Discoveries - 1: Astronomy - 0 views

  •  
    Bill Nye and the Discovery Channel give you the greatest discoveries in science. In this episode, Nye covers Einstein's theory of general relativity, demonstrates how Hubble determined that the universe is expanding, and discusses the 20th-century advancements that help us understand gamma ray bursts, black holes, pulsars, and quasars. Highlights include Edmond Halley, whose discovery of comets orbiting the sun proved that gravity works in space, and Alexander and Caroline Herschel, whose map of the sky brought new understanding of the universe.

Dramatic Health Benefits After Just One Exercise Session - 0 views

  •  
    "Researchers from the University of Michigan discovered that a session of aerobic exercise increases storage of fat in muscle, which actually improves insulin sensitivity. Low insulin sensitivity, or insulin resistance, is an impaired ability of the body to take up sugar from the blood, which can lead to high blood sugar and diabetes."

A Neuroscientist Uncovers A Dark Secret : NPR - 0 views

  •  
    The criminal brain has always held a fascination for James Fallon. For nearly 20 years, the neuroscientist at the University of California-Irvine has studied the brains of psychopaths. He studies the biological basis for behavior, and one of his specialties is to try to figure out how a killer's brain differs from yours and mine.

YouTube - Bill Nye - Greatest Discoveries - 8: Physics - 0 views

  •  
    Bill Nye and the Discovery Channel give you the greatest discoveries in physics. Nye explores how the universe operates and why things move and work the way they do. He also explains the second law of thermodynamics, electromagnetism, and how superconductors can help accelerate particles to near the speed of light. He illustrates Albert Einstein's theory that clocks tick slower at the speed of light and even on an airplane, and discusses how E=MC2 helped develop nuclear power, the quantum leap, the power of electromagnetic energy, the structure of an atom, and the subatomic particles known as quarks.

Human-Powered Ornithopter Becomes First Ever To Achieve - 0 views

  •  
    "Aviation history was made when the University of Toronto's human-powered aircraft with flapping wings became the first of its kind to fly continuously. The "Snowbird" performed its record-breaking flight on August 2 at the Great Lakes Gliding Club in Tottenham, Ont., witnessed by the vice-president (Canada) of the Fédération Aéronautique Internationale (FAI), the world-governing body for air sports and aeronautical world records."

Newly discovered planet may be first truly habitable exoplanet - UC Santa Cruz - 0 views

  •  
    "A team of planet hunters led by astronomers at the University of California, Santa Cruz, and the Carnegie Institution of Washington has announced the discovery of an Earth-sized planet (three times the mass of Earth) orbiting a nearby star at a distance that places it squarely in the middle of the star's "habitable zone," where liquid water could exist on the planet's surface. If confirmed, this would be the most Earth-like exoplanet yet discovered and the first strong case for a potentially habitable one."

Orange peels, newspapers may lead to cheaper, cleaner ethanol fuel - 0 views

  •  
    "University of Central Florida professor Henry Daniell has developed a groundbreaking way to produce ethanol from waste products such as orange peels and newspapers. His approach is greener and less expensive than the current methods available to run vehicles on cleaner fuel -- and his goal is to relegate gasoline to a secondary fuel."
