A recent study from North Carolina State University shows how this might work. Researchers there used video cameras to monitor the faces of college students participating in computer tutoring sessions. Using software that had been trained to match facial expressions with different levels of engagement or frustration, the researchers were able to recognize when students were experiencing difficulty and when they were finding the work too easy.

The project suggests a way for technology to help teachers keep track of students’ performance in real time. Perhaps it could even help massively open online courses (or MOOCs), which can involve many thousands of students working remotely, to be more attuned to students’ needs (see “The Crisis in Higher Education”).

The Fed said its holdings of U.S. securities kept for overseas central banks fell $29 billion in the week ended June 26, to stand at $3.3 trillion.

Monsignor Nunzio Scarano works in the Vatican’s financial administration. A secret service agent and a financial broker have also been arrested.

Parents at high risk of having children with severe disabilities such as muscular dystrophy will be offered the controversial new IVF treatment after it was given the green light by ministers today.

It means the world’s first “three-parent baby” could be born in Britain by 2015, if detailed proposals for regulating the procedure pass a public consultation and are approved by Parliament next year.

Up to 10 patients per year are expected to undergo the treatment, which involves replacing a fraction of the mother’s damaged DNA with that of a healthy donor.

The process avoids the risk of the mother passing inherited defects, which can lead to a host of rare and debilitating conditions affecting the heart, muscles and brain, on to her children.

The sun produces a plasma of charged particles called the solar wind, which get blown supersonically from its atmosphere at more than 1 million km/h. Some of these ions are thrown outward by as much as 10 percent the speed of light. These particles also carry the solar magnetic field.

Eventually, this wind is thought to hit the interstellar medium – a completely different flow of particles expelled from the deadly explosions of massive stars. The extremely energetic ions created in these bursts are known as galactic cosmic rays and they are mostly blocked from coming into the solar system by the solar wind. The galaxy also has its own magnetic field, which is thought to be at a significant angle to the sun’s field.

Researchers know that Voyager 1 entered the edge of the solar wind in 2003, when the spacecraft’s instruments indicated that particles around it were moving subsonically, having slowed down after traveling far from the sun. Then, about a year ago, everything got really quiet around the probe. Voyager 1’s instruments indicated at the solar wind suddenly dropped by a factor of 1,000, to the point where it was virtually undetectable. This transition happened extremely fast, taking roughly a few days.

At the same time, the measurements of galactic cosmic rays increased significantly, which would be “just as we expected if we were outside the solar wind,” said physicist Ed Stone of Caltech, Voyager’s project scientist and lead author of one of the Science papers. It looked almost as if Voyager 1 had left the sun’s influence.

So what’s the problem? Well, if the solar wind was completely gone, galactic cosmic rays should be streaming in from all directions. Instead, Voyager found them coming preferentially from one direction. Furthermore, even though the solar particles had dropped off, the probe hasn’t measured any real change in the magnetic fields around it. That’s hard to explain because the galaxy’s magnetic field is thought to be inclined 60 degrees from the sun’s field.

“You know, for us, this would have been a dream come true,” he said, recalling the days when he was a lieutenant colonel in the defunct communist country’s secret police, the Stasi.

In those days, his department was limited to tapping 40 phones at a time, he recalled. Decide to spy on a new victim and an old one had to be dropped, because of a lack of equipment. He finds breathtaking the idea that the U.S. government receives daily reports on the cellphone usage of millions of Americans and can monitor the Internet traffic of millions more.

“So much information, on so many people,” he said.

East Germany’s Stasi has long been considered the standard of police state surveillance during the Cold War years, a monitoring regime so vile and so intrusive that agents even noted when their subjects were overheard engaging in sexual intercourse. Against that backdrop, Germans have greeted with disappointment, verging on anger, the news that somewhere in a U.S. government databank are the records of where millions of people were when they made phone calls or what video content they streamed on their computers in the privacy of their homes.

Even Schmidt, 73, who headed one of the more infamous departments in the infamous Stasi, called himself appalled. The dark side to gathering such a broad, seemingly untargeted, amount of information is obvious, he said.
