Smivs writes “The BBC are reporting on the development of tiny motors the size of a grain of salt which could power surgical Microbots. Some surgical procedures are hindered by the size or inflexibility of current instruments. For example, the labyrinthine network of blood vessels in the brain prevents the use of catheters threaded through larger blood vessels. Researchers have long envisioned that trends of miniaturisation would lead to tiny robots that could get around easily in the body. The problem until now has been powering them. Conventional electric motors do not perform as well as they are scaled down in size. As they approach millimetre dimensions, they barely have the power to overcome the resistance in their bearings. Now, research reported in the Journal of Micromechanics and Microengineering has demonstrated a motor about 1/4mm wide, about the width of two human hairs.”

According to reports, a number of mobile phone networks faced overload circumstances that day until late afternoon, when the chat sessions finally began to dissipate. Having the most trouble that morning appears to have been T-Mobile, and AT&T also had some difficulty that morning.”

Astronomers at the Harvard-Smithsonian Center for Astrophysics have discovered a planet somewhat larger and more massive than Neptune orbiting a star 120 light-years from Earth.

Net neutrality really is the hot topic at the moment. After the FCC slapped Comcast for slowing down BitTorrent users, Canada is now looking into the network management practices of its ISPs. And rightly so, as a CRTC investigation reveals that most of the ISPs in Canada actively slow down customers using P2P applications.

Your college roommate is on Facebook. So are your cousins and colleagues and friends. But guess who else may find Facebook a great way to stay in touch? Some people in Sicily who know a few things about networking. Authorities are investigating groups devoted to Mafiosi.

KentuckyFC writes “The pattern of citations between scientific papers forms a network that has remarkable similarities to the network formed by the web. So why not use Google’s PageRank, the world’s most effective search algorithm to rank these papers in the same way it ranks websites? That’s exactly what a couple of US researchers have done for physics papers published by the American Physical Society since 1893 (abstract). The results make interesting reading because almost all of the top ten papers resulted in (or were linked to) Nobel Prizes for their authors. Which means that studying the up-and-coming entries on the list ought to be a good way of predicting future winners. Better get your bets in before the bookies get wind of this.”
