Quantum Computing Leap Forward: Altering a Lone Electron Without Disturbing Its Neighbors

Jason Petta, an assistant professor of physics, has found a way to alter the property of a lone electron without disturbing the trillions of electrons in its immediate surroundings. Such a feat is an important step toward developing future types of quantum computers. (Credit: Princeton University, Office of Communications, Brian Wilson)

From Science Daily:

Science Daily (Feb. 6, 2010) — A major hurdle in the ambitious quest to design and construct a radically new kind of quantum computer has been finding a way to manipulate the single electrons that very likely will constitute the new machines' processing components or "qubits."

Why We Gamble: The Enticement Of Almost Winning

From Live Science:

Betting on the Super Bowl, roulette, or even online poker can be thrilling, and with the advent of online gambling, it's easier than ever before. Yet winning and losing can have unexpected effects on the brain that keep people coming back for more, scientists are finding.

Gamblers sink an increasing sum of money into their efforts to win. Over the last 20 years legalized betting has grown tremendously; it's now a $100 billion industry. More than 65 percent of Americans gamble, according to Gallup's annual Lifestyle Poll conducted last year, and up to 5 percent of those betters develop an addiction to the activity.

Justice Dept. to Google Books: Close, But No Cigar

From Epicenter:

Google’s plan to digitize the world’s books into a combination research library and bookstore has hit another snag, in the form of a U.S. Justice Department statement that “despite substantial progress made, issues remain” with the proposed settlement agreement of the class action lawsuit The Authors Guild Inc. et al. v. Google Inc.

The Justice Department joins key members of The Authors Guild in applauding some of the changes Google and the guild have made to their proposed agreement, submitted in September, including the elimination of Google’s right to the books for unspecified future uses, the creation of a new position to represent unknown rights holders, and a mechanism allowing competing companies to license Google’s library to offer competing products.

The Big Question: What Do We Know About The Human Brain And The Way It Functions?

Independent Graphics

From The Independent:

Why are we asking this now?

Scientists this week announced that they had succeeded in communicating with a man thought to be in a vegetative state, lacking all awareness, for five years following a road accident. Using a brain scanner they were able to read his thoughts and obtain yes or no answers to questions. They asked him to imagine playing tennis if he wanted to answer yes and to imagine walking through his home if he wanted to say no. By mapping the different parts of the brain activated in each case with the scanner, the scientists were able accurately record his reponses.

21st Century Energy: Some Sobering Thoughts

From OECD Observer:

Transition to new energy sources is unavoidable, but here are five sobering first principles to remember along the way.

Are we about to switch to new energy sources? Grandiose plans are being drawn up for installing veritable forests of giant wind turbines, turning crops and straw into fuel ethanol and biodiesel, and for tapping solar radiation by fields of photovoltaic cells. As with most innovations, there is excitement and high expectation. Will these developments and other renewable energy conversions one day replace fossil fuels? Eventually they will have to, but a reality check is in order.

Whether you hoped to buy an e-book for the Kindle, or an old-fashioned physical book, Amazon wouldn’t sell it to you. In a protest against the pricing model that MacMillan and other publishers had negotiated with Apple for the iBookstore, Amazon simply removed the “buy” button from MacMillan’s books.

The protest didn’t last very long — just long enough to be noticed and to make the New York Times on the evening of January 29. By the evening of the 31st, Amazon had relented, with the following statement:

The opinion filed Thursday in New York federal court is a significant setback in Google's effort to win approval of a 15-month-old legal settlement that would put the Internet search leader in charge of a vast electronic library and store. A diverse mix of Google rivals, consumer watchdogs, academic experts, literary agents, state governments and even foreign governments have already urged U.S. District Judge Denny Chin to reject the agreement.

Mike Brown, from the California Institute of Technology, suggested Pluto had the most dynamic surface of any object in the Solar System.

Hubble will provide our sharpest views of Pluto until the New Horizons probe approaches in 2015.

Solar Flares Back, But Oddly Small

SYDNEY: After a long silence, the Sun erupted in an unusual pattern of small solar flares, said an Australian astrophysicist, which may provide a unique opportunity to predict when bigger solar flares will erupt.

Solar flares are explosions in the Sun's atmosphere marked by a burst of X-rays. They increase or decrease in a roughly 11-year cycle — larger flares can reach tens of millions of degrees Celsius and interfere with communications satellites and affect astronauts' health.

Bees See Your Face As A Strange Flower

Bees can learn to recognize human faces, or at least face-like patterns, a new study suggests.

Rather than specifically recognizing people, these nectar-feeding creatures view us as "strange flowers," the researchers say. And while they might not be able to identify individual humans, they can learn to distinguish features that are arranged to look like faces.

The results suggest that, even with their tiny brains, insects can handle image analysis. The researchers say that if humans want to design automatic facial recognition systems, we could learn a lot by using the bees' approach to face recognition.

Great (and Not So Great) Spaced Out Super Bowl Ads

From Discovery News:

As the Super Bowl weekend begins, excitement (or dread) is building for the infamous Super Bowl commercials that will grace our screens at half time. I'm hoping there might be one or two space-themed ads.

Last year, the tire company Bridgestone knocked it out of the park with astronauts dancing to House of Pain's hit tune "Jump Around" on an alien planet/moon only to return to their rover to find its tires had been stolen by thieving aliens.

Unfortunately, the Bridgestone effort is more of an exception than a rule, because some of the other space-themed Super Bowl ads can be on the wrong side of "cheesy" (but don't worry, I doubt there will be any ill effects from bad-ad exposure).

"We're not going to put up more wind (in many locations) without conflict because radar systems and wind systems love exactly the same terrain...which is where the wind is at," said Gary Seifert, a program manager for renewable energy technologies at the Idaho National Laboratories, during a presentation at the RETECH conference here on Thursday.

What Really Motivates Sperm

From Live Science:

In high-school health class films, sperm cells are shown zooming around with quick flicks of their tails, but they only jump into action when they are in the right chemical conditions – usually that's in the female reproductive tract. Researchers have now figured out the precise chemical switch that turns on the sperm's motors, which could lead to the development of new treatments for infertility.

Scientists have long known that sperm's activity level depends on the internal pH of the sperm cell —a measure of how acidic or alkaline a substance is. They start out with acidic insides when in the male reproductive tract, but once they enter the female tract, their internal environment becomes alkaline and off they zoom toward the egg.
