Single Title Player with Ad. Science & Unchained Dreams. Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing? Stephen Hawking. Braille Interpreter by Hyung Jin Lim & Yanko Design.

Here are some words that few would have thought to put together: video game therapy.

Playing video games helps adults with lazy eye

Yet, a pilot study by vision researchers at the University of California, Berkeley, has found that playing video games can help improve the vision of adults with amblyopia, or lazy eye. The study found that participants experienced marked improvement in visual acuity and 3-D depth perception after spending just 40 hours playing off-the-shelf video games. A UC Berkeley pilot study suggests that video games could help treat adults with amblyopia. “This study is the first to show that video game play is useful for improving blurred vision in adults with amblyopia,” said study lead author Dr.

When it comes to muscles, Mother Nature has come up with a brilliant structure. But could the structure be even stronger? Scientists from the NanoTech Institute at the University of Texas at Dallas are coming up with a way to use carbon nanotubes as the material for muscles modeled after natural structures.

s Gravity Probe B confirms two Einstein theories - StumbleUpon

Stanford and NASA researchers have confirmed two predictions of Albert Einstein's general theory of relativity, concluding one of the space agency's longest-running projects. Known as Gravity Probe B, the experiment used four ultra-precise gyroscopes housed in a satellite to measure two aspects of Einstein's theory about gravity. Web Publications. @GrrlScientist. This week's element is Yttrium, known by the atomic symbol, Y, and the atomic number 39.


Originally, its atomic symbol was Yt, but sometime in the early 1920s, it was replaced by Y. This element gets its strange name from the village of Ytterby in Sweden, which is located near where this element was discovered. As you can see in the above image, Yttrium is similar to many other elemental metals; it is a silver-grey in colour. It also is soft, lustrous and highly crystalline. Glow-in-the-dark mushroom rediscovered after 170 years. It's something you would never expect to go missing, but one of the world's brightest glow-in-the-dark mushrooms has been rediscovered after an absence of more than 170 years, according to USA Today. The bioluminescent shrooms had become a Brazilian legend of sorts. They were first spied in 1840 by an English botanist named George Gardner, who was alarmed after he saw some boys playing with a glowing object in the streets of Vila de Natividad, a village in the Goiás state in central Brazil.

After that, no more sightings of the brightly glowing fungus had ever been reported. The mushroom was nearly forgotten until 2002, when Brazilian chemist Cassius Stevani came across Gardner's early reports. Heads Up, Hoverboarders: Here Comes Quantum Levitation.

Robert Barker/University Photography The human hand is an amazing machine that can pick up, move and place objects easily, but for a robot, this "gripping" mechanism is a vexing challenge.

Universal robotic gripper - StumbleUpon

Opting for simple elegance, researchers from Cornell, the University of Chicago and iRobot Corp. have created a versatile gripper using everyday ground coffee and a latex party balloon, bypassing traditional designs based on the human hand and fingers. They call it a universal gripper, as it conforms to the object it's grabbing, rather than being designed for particular objects, said Hod Lipson, Cornell associate professor of mechanical engineering and computer science.

The research is a collaboration between the groups of Lipson, Heinrich Jaeger at the University of Chicago, and Chris Jones at iRobot.

—Researchers at the California Institute of Technology (Caltech) have created a nanoscale crystal device that, for the first time, allows scientists to confine both light and sound vibrations in the same tiny space. "This is a whole new concept," notes Oskar Painter, associate professor of applied physics at Caltech. Painter is the principal investigator on the paper describing the work, which was published this week in the online edition of the journal Nature. Extraordinary lightning sprites discovered striking other planets, not just... By Daily Mail Reporter Updated: 17:29 GMT, 22 November 2011 It was only a couple of decades ago scientists discovered the existence of upwards lightning or ‘sprites’ 30 to 55 miles above the surface of the Earth.

At least, that’s what some popular press articles have suggested since researchers with the OPERA experiment in Italy presented evidence of neutrinos arriving 60 nanoseconds earlier than thought possible. But scientists, quite intrigued by the anomalous results, have since been busy generating more measured responses. Chronology of Events in Science, Mathematics, and Technology - StumbleUpon.

Nope, says Obama administration. The United States government has no evidence of alien life.

That's the word from the Obama administration in response to two online petitions that asked for full disclosure on government knowledge of UFOs and extraterrestrials. "The U.S. government has no evidence that any life exists outside our planet, or that an extraterrestrial presence has contacted or engaged any member of the human race," writes Phil Larson of the White House Office of Science & Technology Policy.
