Best of Last Week—Transferring quantum states, wireless energy breakthrough and a drug that helps Alzheimer's patients

It has once again been an interesting week for physics—a team working in China demonstrated . They showed it was possible, using entanglement, to send quantum information between two distant points without having to send anything else. Also, a team of astrophysicists has found Actual measurements used to calculate the total amount of lithium in the universe have not jibed with theory, and now a team at Université Savoie Mont Blanc is suggesting that the problem may be connected to the theory of electromagnetic cascades.

In other space news, and a team in China reported that —its radar found at least nine distinct rock layers. And . Meanwhile, another team of researchers found evidence that suggests —perhaps 50 percent larger.

In unrelated news, a team of researchers at Vanderbilt University has developed . By studying the ways brain areas communicate with one another during the time when a person is engaged in conscious thought and applying graph theory, the team believes they have found a way to show that thinking is nothing more than widespread communication between parts of the brain. Also, a team of researchers with the Japan Aerospace Exploration Agency announced that they had made —they found a way to use microwaves to deliver 1.8 kilowatts of power through the air to a receiver 55 meters away, potentially opening the door to a whole new way to tap solar energy.

And finally, exciting news for baby boomers and others of their generation, a team of researchers has found . Thus far, it appears it might be useful for use in patients who are believed to be at high risk of developing the disease.
