Virtual reality schemes have long tantalized geeks with unrealized visions of holodecks and long-distance cybersex.
Now, a group of British researchers want to round out the experience with virtual touch, taste and smell. To simulate the real world, they argue, all five of your senses must be stimulated. Toward that end, they’ve mocked up a "Virtual Cocoon" with a separate glove that — at least in theory — could tickle your tongue as it, uh, nukes your nose.
To differentiate themselves from virtual reality schemes that have come and gone, the researchers are re-branding their effort as "real virtuality."
"The crucial …

Scientists searching for extraterrestrial life might want to start digging under a Martian mountain three times as high as Mount Everest. 
Liquid water likely once sloshed beneath the 15-mile-high Olympus Mons, and may still be there today. Because the mountain is volcanic, the water could be warm and friendly to life. 
"Olympus Mons is a favored place to find ongoing life on Mars," said geophysicist Patrick McGovern of Houston’s Lunar and Planetary Institute, lead author of a study in Geology in February. "An environment that’s warm and wet, and protected from adverse surface conditions, is a great place to start …

 
 
NASA’s planet-hunting space telescope Kepler is slated to launch the night of March 6 from Kennedy Space Center in Cape Canaveral, Florida, on a mission to find Earth-sized planets that could have liquid water at the surface and potentially harbor life. 
"It’s not just another science mission. This one has historical significance built into it," said Ed Weiler of the Science Mission Directorate at NASA headquarters. "It very possibly could tell us that earths are very, very common, that we’ve got lots of neighbors out there. Or it could tell us that Earths are really, really, really rare."

For a …

Animals shrunken by the evolutionary pressures of hunting and fishing could someday recover their lost splendor.
After being left alone for just twelve generations, a population of experimentally stunted fish regained most of their original size — suggesting that the real-world dwarfism produced by continually killing the largest specimens may not be permanent.
"There’s a fair amount of evidence now that in lots of hunted or harvested populations, there’s a trend towards smaller body sizes or earlier ages at maturation," said Stephan Munch, a marine ecologist at Stony Brook University. "There’s been relatively little evidence for what happens after you …

Like hackers one-upping each others’ code, stem cell scientists keep finding better ways to turn flakes of skin into stem cells. And the latest technique could avoid the cancer-causing side effects of previous methods.
By reprogramming skin cell DNA with a virus that literally removed itself afterwards, researchers have made a versatile, near-embryonic stem cell nearly free from glitches left by other manufacturing methods.
"The virus steadily integrates into the cell’s genome. It does the miracle of reprogramming," said Rudolf Jaenisch, a Whitehead Institute cell biologist. Activating a gene in the virus "takes the virus back out, leaving a minimal …

ARGONNE, Illinois — In the basement of a nondescript building here at Argonne National Laboratory, nickel particles in a beaker are building themselves into magnetic snakes that may one day give clues about how life originally organized itself.
These chains of metal particles look so much like real, living animals, it is hard not to think of them as alive. (See exclusive video below.) But they are actually bits of metal that came together under the influence of a specially tuned magnetic field.
"It behaves like some live object," says physicist Alex Snezhko. "It moves. It crashes onto free-floating particles and …

Genetics research is pretty exciting, but it would be far more entertaining if lab instruments could transform into killer robots.
In the real world, DNA copying machines, perform a tremendously mundane task, repeatedly heating and cooling little vials of liquid. But in this viral ad, made by a marketing team that calls itself Bison, the latest product from Roche has ninja skills and a penchant for blowing things up. And it wants revenge.
"Roche wanted to do something big," says Tyler Kay, the founder of Bison. "Why not turn their Real-Time PCR thermal cycler into an ass-kicking robot?"
Since 2005, instrument …

An uber-primitive plant pathogen made from naked strands of genetic material mutates faster than any other known organism — and it might just illuminate the origins of life.
Called hammerhead viroids, their mutation rates are orders of magnitude more rapid than those of viruses, the next-most-primitive
organisms, which are orders of magnitude more rapid than
lowly bacteria.
In less academic terms, the hammerhead viroid blueprint of life is being constantly redrawn.
Such accelerated mutation could have been useful four billion years ago, after a few quirky chemicals assembled into ribonucleic acid, or RNA — DNA’s single-stranded forerunner.
At the time, hypothesize scientists, the pinnacle …

A new telescope that will be able to detect earth-like planets around other stars successfully launched Friday night from Kennedy Space Center in Cape Canaveral, Florida at 10:49 p.m. Eastern time.
The Kepler Space Telescope is the first human tool that will be able to find planets capable of supporting life as we know it.
Its trip into orbit went exactly as planned, with the @NASA twitter feed declaring it, "A perfect launch!"
NASA Headquarters sent out a release at 1:00 am in which Kepler’s project manager drew attention not just to the launch, but the telescope’s ultimate mission.
"It was …
