MikeChino writes with this snippet from Inhabitat: "Researchers at Stanford University recently announced that they have developed a new artificial retina implant that uses photovoltaic power and could help the blind see. The problem with previous implants was that there was no way send power to the chip in order to process light and data inside the eye, so the new device uses miniature photovoltaic cells to provide power the chip as well as to transmit data through the eye to the brain. The new device has great promise to help people afflicted by the loss of photoreceptor cells by using the power of the sun."

National Geographic is reporting that the migration of Earth's magnetic pole has accelerated again and is now racing in Russia's direction at a blazing 40 miles per year. This movement began in earnest around 1904 at about 9 miles per year and has been accelerating since. "Geologists think Earth has a magnetic field because the core is made up of a solid iron center surrounded by rapidly spinning liquid rock. This creates a 'dynamo' that drives our magnetic field. Scientists had long suspected that, since the molten core is constantly moving, changes in its magnetism might be affecting the surface location of magnetic north. Although the new research seems to back up this idea, Chulliat is not ready to say whether magnetic north will eventually cross into Russia. 'It's too difficult to forecast,' Chulliat said. Also, nobody knows when another change in the core might pop up elsewhere, sending magnetic north wandering in a new direction."

The Telegraph is reporting that for the first time an extinct animal has been brought back via cloning. The Pyrenean ibex, a type of mountain goat, was declared officially extinct in 2000, but thanks to preserved skin samples scientists were able to insert that DNA into eggs from domestic goats to clone a female Pyrenean ibex. While the goat didn't survive long due to lung defects this gives scientists hopes that it will be possible to resurrect extinct species from frozen tissue. "Using techniques similar to those used to clone Dolly the sheep, known as nuclear transfer, the researchers were able to transplant DNA from the tissue into eggs taken from domestic goats to create 439 embryos, of which 57 were implanted into surrogate females. Just seven of the embryos resulted in pregnancies and only one of the goats finally gave birth to a female bucardo, which died seven minutes later due to breathing difficulties, perhaps due to flaws in the DNA used to create the clone."

The Bad Astronomer writes "Five years ago today (December 27, 2004), a vast wave of high-energy gamma and X-rays washed over the Earth, blinding satellites and partially ionizing the Earth's atmosphere. The culprit was a superflare from the magnetar SGR 1806-20, located 50,000 light years away. The energy released was mind-numbing: in one-fifth of a second, this supercharged magnetic neutron star blasted out as much energy as the Sun does in 250,000 years!"

An article in the LA Times calls NASA out for failing to make broadcasts on their dedicated television network as entertaining as they can be. The author, David Ferrell, complains that fascinating subject matter is often fraught with boring commentary and frequent, extended silences, making most people quickly lose interest. Quoting: "Witness one recent segment about the recovery of a Soyuz capsule upon its return to Earth. The dark, bullet-like object landed in the featureless steppes of Kazakhstan, about 50 miles outside the unheard-of town of Arkalyk. Coverage consisted of video shot from an all-terrain vehicle approaching it — mostly soundless footage of tall grass going by — with an occasional word by an unnamed commentator. 'You can see the antenna that deployed shortly after landing,' the commentator said in that deadpan tone shared by scientists and golf announcers. The camera chronicled the tedious extraction of three crew members weakened by spending six months in orbit; they were loaded one by one onto stretchers. 'Again, a rather methodical process,' the commentator noted, as if grasping for something — anything — to say. Later: 'The official landing time has been revised to 1:15 and 34 seconds a.m., Central Time. The official time was recorded at the Russian Mission Control Center . . . by the Russian flight-control team.' ... Where is Carl Sagan when you need him?"

Ada_Rules writes "Researchers at the Imperial College London have announced development of an alcohol substitute that has many of the same properties as the Synthehol from the series Star Trek, in that one will get a buzz from it but will not end up with a hangover. In addition you will have the option of getting immediately sober if you so desire it. Let's hope this is not the typical vaporware. It is not that I really want a drink of Synthehol, but with its release I assume Romulan Ale won't be far behind."

Dr_Ken writes with a quote from Scientific American: "The human body has some 10 trillion human cells—but 10 times that number of microbial cells. So what happens when such an important part of our bodies goes missing? With rapid changes in sanitation, medicine and lifestyle in the past century, some of these indigenous species are facing decline, displacement and possibly even extinction. In many of the world's larger ecosystems, scientists can predict what might happen when one of the central species is lost, but in the human microbial environment—which is still largely uncharacterized—most of these rapid changes are not yet understood. 'This is the next frontier and has real significance for human health, public health and medicine,' says Betsy Foxman, a professor of epidemiology at the University of Michigan School of Public Health in Ann Arbor. Meanwhile, each new generation in developed countries comes into the world with fewer of these native populations. 'They're actually missing some component of their microbiota that they've evolved to have,' Foxman says."

Dananajaya Ramanayake sends along this excerpt from Wired: "Nearly 62 years after researchers at Bell Labs demonstrated the first functional transistor, scientists say they have made another major breakthrough. Researchers showed the first functional transistor made from a single molecule. The transistor, which has a benzene molecule attached to gold contacts, could behave just like a silicon transistor. The molecule's different energy states can be manipulated by varying the voltage applied to it through the contacts. And by manipulating the energy states, researchers were able to control the current passing through it."

gamebittk writes "In 1959, Soviet scientist Dmitri Belyaev set out to breed a tamer fox that would be easier for their handlers in the Russian fur industry to work with. Much to the scientist's shock, changes no one had expected emerged after just 10 generations. The foxes began behaving playfully, were smaller in size, and even changed color — much like dogs." Belyaev died in 1985, but the experiment continued (PDF) in his absence, and to this day provides strong evidence to parts of evolutionary theory. The experiment eventually branched out to involve other species as well.

Santa Claus must use advanced technologies to pull off his annual feat. Thankfully, NewScientist has the exclusive about the what and the how. "He relies on some impressive gadgets: miniature flying robots, advanced satellites, highly sensitive surveillance devices, memory-erasing milk, self-assembling toys, and a warp-drive-powered sleigh that's capable of bending and twisting space-time to such an extent that it slips Santa and his reindeer out of the observable universe. In 1949, Kurt Gödel published one of the first mathematical descriptions of how it could work. In his version, the universe has paths called closed time-like curves that might allow you to jump in a ship, fly for a while, and end up right back where you started in space and time."
