MIT scientists have brought a supercool end to a heated race among physicists: They have become the first to create a new type of matter, a gas of atoms that shows high-temperature superfluidity.
Experts have long known that the brain has the ability to suspend the pain response in times of injury and great stress, even after traumatic incidents such as gunshot wounds.
Now, a new study in rats suggests marijuana-like neurochemicals called endocannabinoids may be key to this process.
The discovery may lead to a new class of painkillers with fewer side effects than existing pain medications, report researchers at the University of California, Irvine (UCI). Their study appears in the June 23 issue of Nature.
Computer scientists in the US are developing a system which would allow people to "teleport" a solid 3D recreation of themselves over the internet.
Professors Todd Mowry and Seth Goldstein of Carnegie Mellon University in Pennsylvania think that, within a human generation, we might be able to replicate three-dimensional objects out of a mass of material made up of small synthetic "atoms".
Cameras would capture the movement of an object or person and then this data would be fed to the atoms, which would then assemble themselves to make up an exact likeness of the object.
A small planet just seven or eight times as massive as the Earth has been found circling a nearby star. Astronomers say it is the most Earth-like world we have ever seen beyond our solar system.
"For the first time, we are beginning to find our planetary kin among the stars," says Geoff Marcy of the University of California at Berkeley, US. His team announced the discovery at a news conference in Arlington, Virginia, US, on Monday.
L33tdawg: Apologies to all the Redhat folks that clicked on this expecting it to be an article about the other Kudzu, the Red Hat Linux hardware probing library and configuration tool :)
An extract from a plant known in the US as "the vine that ate the South" may help reduce alcohol consumption in heavy drinkers, a small-scale study suggests.
