Physicists Make Artificial Black Hole Using Optical Fiber
Physicists and astronomers believe that black holes are formed when huge stars collapse in on themselves at the end of their lives. They exist at the centers of galaxies, where they act as giant engines that drive the motion of stars, according to astronomers. However, studying them is extremely difficult, particularly because in astronomy one can study only the information carried by light. In the case of black holes, the absence of light means astrophysicists have to rely on indirect means, such as inferring the presence of black holes by the way their gravity bends light outside their event horizons—a phenomenon scientists call gravitational lensing.
Having access to an artificial black hole in the lab will allow astrophysicists to test predictions made by theorists. Physicists would particularly like to test new theories such as quantum gravity, which seeks to reconcile Einstein’s theory of general relativity with quantum mechanics.

Netflix Prize
In October 2006, Netflix announced a grand prize of one million dollars for a better movie-recommending algorithm that is at least 10 percent better than its own. Within two weeks, the DVD rental company had received 169 submissions, including three that were slightly superior to Cinematch, Netflix's recommendation software. After a month, more than a thousand programs had been entered, and the top scorers were almost halfway to the goal. But what started out looking simple suddenly got hard. The contest is expected to continue until 2011.

Mind Reading with Functional MRI
According to the study, published in the the journal Nature, scientists first gathered information about how the brain processes images by recording activity in the visual cortex as subjects looked at several thousand randomly selected pictures. Neurons in this part of the brain respond to specific aspects of the visual scene, such as a patch of strongly contrasting light and dark, so the activity recorded in each area of the brain scan reflects the visual information being processed by neurons in that area of the brain. The researchers compiled this information to develop a computer model that would predict the pattern of brain activity triggered by any image.
When volunteers were later shown a new image not included in the first set, the computer model was able to correctly predict which picture out of 120 or 1,000 possibilities the person looked at with 90 or 80 percent accuracy, respectively.
"They can do this with a surprising degree of accuracy," says Frank Tong, a neuroscientist at Vanderbilt University, in Nashville, TN, who was not involved in the research. "People will be struck by how much visual information these researchers were able to extract from the brain."

Wireless Power Transmission: Tesla Revisited
Then, a few years ago, Marin Soljačić, an assistant professor of physics at MIT started searching for ways to transmit power wirelessly. Instead of pursuing a long-distance scheme like Tesla's, he decided to look for midrange power transmission methods that could charge--or even power--portable devices such as cell phones, PDAs, and laptops.
So far, the most effective setup consists of 60-centimeter copper coils and a 10-megahertz magnetic field; this transfers power over a distance of two meters with about 50 percent efficiency. The team is looking at silver and other materials to decrease coil size and boost efficiency. "While ideally it would be nice to have efficiencies at 100 percent, realistically, 70 to 80 percent could be possible for a typical application," says Soljačić.
