Bionic Eye Lets The Blind See
From The Telegraph:
A bionic eye has allowed a blind patient to see well enough to sort his socks and work the washing machine after one of the first operations of its kind in the UK.
Ron, 73, is one of just three patients in the UK to be fitted with a bionic eye and after 30 years of being completely blind he can now see well enough to do the laundry.
The operation was carried out at Moorfields Eye Hospital in London seven months ago and Ron's sight has steadily improved since then.
He lost his sight in his 40s after suffering from a disease called retinitis pigmentosa but now thanks to the operations he is regaining some of his independence.

From Nevada Appeal:
WASHINGTON — For two decades, a ridge of volcanic rock 90 miles northwest of Las Vegas known as Yucca Mountain has been the sole focus of government plans to store highly radioactive nuclear waste.
Not anymore.
Despite the $13.5 billion that has been spent on the project, the Obama administration says it’s going in a different direction.
It slashed funding for Yucca Mountain in its recently announced budget.
And on Thursday, Energy Secretary Steven Chu told a Senate hearing that the Yucca Mountain site no longer was viewed as an option for storing reactor waste, brushing aside criticism from several Republican lawmakers.

The Kepler Telescope: Taking A Census Of The Galaxy
At the Astrotech payload processing facility in Titusville, Florida, workers from Ball Aerospace check the star trackers on NASA's Kepler spacecraft before testing. NASA
From Time Magazine:
Think you could stare at a single spot without blinking for three and a half years? Then be glad you're not NASA's Kepler telescope, which is set to blast into space from Cape Canaveral this Friday night. Kepler's job may sound boring to you, but what the spacecraft accomplishes could be extraordinary: the discovery of the first Earth-like planets orbiting sun-like stars. Those kinds of places might well be brewing Earth-like forms of life.

From Science Daily:
ScienceDaily (Mar. 5, 2009) — Schizophrenia could be caused by faulty signalling in the brain, according to new research published in the journal Molecular Psychiatry. In the biggest study of its kind, scientists looking in detail at brain samples donated by people with the condition have identified 49 genes that work differently in the brains of schizophrenia patients compared to controls.
Many of these genes are involved in controlling cell-to-cell signalling in the brain. The study, which was carried out by researchers at Imperial College London and GlaxoSmithKline, supports the theory that abnormalities in the way in which cells 'talk' to each other are involved in the disease.

Exercise: The Best Medicine
New studies find exercise makes for better eye health, less chronic pain, stronger bones and can even help prevent some cancer. Image credit: Dreamstime
From Live Science:
It just seems too good to be true. Study after research study consistently promoting the endless benefits of exercise. Couch potatoes everywhere are waiting for the other shoe to drop, telling us that all of those scientists were wrong and we should remain as sedentary as possible.
Yet four additional studies released recently each give the same prescription for improving some aspect of your health: exercise.
They add to recent evidence that regular workouts can improve old brains, raise kids' academic performance and give a brain boost to everyone in between.

Asteroid's Near Miss A Cosmic Close Call
From CBS News:
(AP) An asteroid about the size of one that blasted Siberia a century ago just buzzed the Earth.
The asteroid named 2009 DD45 was about 48,800 miles from Earth when it zipped past early Monday, NASA's Jet Propulsion Laboratory reported.
That is just twice as high as the orbits of some telecommunications satellites and about a fifth of the distance to the Moon.
"This was pretty darn close," astronomer Timothy Spahr of the Harvard-Smithsonian Center for Astrophysics said Wednesday.
But not as close as the tiny meteoroid 2004 FU162, which came within 4,000 miles in 2004.

From Technology Review:
The first bendable, touch-screen display will be used by the military.
Researchers have developed the first computer display that is both flexible and touch sensitive. They say that the breakthrough could lead to more practical and easier-to-use portable devices.
Over the past few years, there has been a drive to develop displays that more closely mimic the properties of paper.
E Ink, based in Cambridge, MA, already supplies displays that are easy to read in direct sunlight and require little power for both the Amazon Kindle and the Sony Reader, compared to LCDs and plasma screens. E Ink's technology uses a layer of microcapsules filled with submicrometer black and white particles to create a low-power, reflective screen.

Mould Problem At France's Lascaux Cave
Paleolithic handywork: Discovered in 1940, France's Lascaux Cave has some of the world's most spectacular prehistoric cave art.
From Cosmos Magazine:
PARIS: The problem of black fungus threatening world-famous prehistoric paintings at the Lascaux Cave in southwestern France is stable, a scientist said last week.
France, criticised for its management of Lascaux, applied fungicide to the cave's walls in January 2008 in a bid to roll back patches of mould imperilling the legendary art.
Dubbed "the Sistine Chapel of prehistory," Lascaux, listed as a World Heritage Site by UNESCO, includes stunning pictures of horses, extinct bulls and ibexes, painted by unknown hands some 17,000 years ago.

From Science Daily:
ScienceDaily (Mar. 4, 2009) — NASA's Cassini spacecraft has found within Saturn's G ring an embedded moonlet that appears as a faint, moving pinprick of light. Scientists believe it is a main source of the G ring and its single ring arc.
Cassini imaging scientists analyzing images acquired over the course of about 600 days found the tiny moonlet, half a kilometer (about a third of a mile) across, embedded within a partial ring, or ring arc, previously found by Cassini in Saturn's tenuous G ring.
"Before Cassini, the G ring was the only dusty ring that was not clearly associated with a known moon, which made it odd," said Matthew Hedman, a Cassini imaging team associate at Cornell University in Ithaca, N.Y. "The discovery of this moonlet, together with other Cassini data, should help us make sense of this previously mysterious ring."

From Live Science:
For the first time, scientists have watched as the Earth’s surface “heals” itself following the disruptive jolt of an earthquake, in this case, the 2003 temblor that devastated Bam, Iran.
The fault under the city erupted in a 6.6-magnitude quake on Dec. 26 that year, leveling the town and killing more than 26,000 people. But though devastation was evident, there was no clear fault mark at the surface.
"The fault slipped maybe 2 or 3 meters [6.5 to 10 feet] at depth, but at the surface, when colleagues of mine went out, they found some cracks, but the motion on those cracks is only about up to 25 centimeters [10 inches] or less," said one of the scientists who studied the quake, Eric Fielding of Caltech. "We have some layer of material near the surface that's behaving differently from the fault at depth."

which is 100million light years away
which is 100million light years away
From The Daily Mail:
A dramatic Hubble image has captured three galaxies locked in a gravitational tug-of-war that may lead to one of them being ripped apart.
It is likely the outcome has long since been decided, as the epic life or death battle is in the constellation of Piscis Austrinus, or Southern Fish, 100 million light-years away.
The new picture from the Advanced Camera for Surveys on the Hubble Space Telescope allows astronomers to view the movement of gases from galaxy to galaxy, revealing the intricate interplay among them.
