Carnegie Mellon University researchers have developed a new series of robots that are simple enough for almost anyone to build with off-the-shelf parts, but are sophisticated machines that wirelessly connect to the Internet.

University of Rochester physicists have combined an atom-chiller with a molecule trap, creating for the first time a device that can generate and trap huge numbers of elusive-yet-valuable ultracold polar molecules.
Scientists believe ultracold polar molecules will allow them to create exotic artificial crystals and stable quantum computers. Quantum computer scientists are attracted to ultracold particles because their temperatures reduce decoherence, a phenomenon where a system decays from the… read more

Scientists are developing ways of capturing human movement in three dimensions which would allow music to be created or web pages browsed with the gesture of an arm.
The system captures 3D movements using infrared light projected onto tiny reflective balls attached to clothing and monitored by 12 cameras.
The computer tracks the changing positions of the balls and turns different gestures into instructions for music software.

Masashi Kimura at Osaka City University in Japan has looked at the possibility of black rings — a variant of black holes — or other shapes forming in higher dimensional space.

A Scottish church which featured in the best-selling novel “The Da Vinci Code” has revealed another mystery hidden in secret code for almost 600 years.
“The music has been frozen in time by symbolism,” said Thomas Mitchell, a 75-year-old musician and ex-Royal Air Force code breaker, on his Web site, which details the 27-year project to crack the chapel’s code.

Kyushu Central Hospital researchers have used fat-derived stem cells to help reshape the breasts of women who have undergone a lumpectomy to remove a breast tumor.
While the research is still early, it is thought that the stem cells develop into the cells needed to form new blood vessels.

Toshiba and its partners yesterday raised the tempo in the battle to determine the next-generation DVD format, saying they were on track to launch next year a DVD recorder capable of storing more than eight hours of high-resolution content on one disc (around 27GB for single-layer and 54GB for dual-layer discs).
Microsoft’s Japanese unit, meanwhile, said the company’s next Windows-based operating system, called Longhorn, would be compatible with HD-DVD.… read more
Taking the next step beyond silicon integrated circuits, engineers at the University of California, Davis have developed a new approach that allows nonsilicon nanowires and other nanostructures to be combined with silicon surfaces.
It shows promise for a new generation of fast, robust electronic and photonic devices.
Bypassing silicon’s limits
Circuits built on conventionally etched silicon have reached their lower size limit, which restricts operation… read more

Darpa’s latest venture, called “Physical Intelligence” (PI) intends to prove mathematically that all brain activities — reasoning, emoting, processing sights and smells — derive from physical mechanisms, acting according to the principles of “thermodynamics in open systems.”
They’re asking for “abiotic, self-organizing electronic and chemical systems” that display the PI principles. Darpa wants to re-envision how thought works — and then design computers whose thought processes are governed by… read more

Researchers at the Whitehead Institute for Biomedical Research have identified short stretches of the proteins that control how prions form, replicate, and cross between species.
These small but critical regions of the proteins may be responsible for prions’ infectious nature–and scientists may be able to use them to create treatments for prion diseases.

Two kittens have been born using a new cloning method that may be safer and more efficient than traditional methods, according to Genetic Savings & Clone.
The company used a new method called chromatin transfer that tries to produce a cloned embryo that more closely resembles a normal embryo.
It involves dissolving the outside of the nucleus of the cell to be cloned and removing certain regulatory proteins… read more

The probability that the universe it flat may only be 67 percent because WMAP observations of the density of matter and dark energy in the early universe may have been misinterpreted, says Joseph Silk at the University of Oxford and colleagues, based on a new study.
The universe could also be positively curved (like the surface of a sphere) or negatively curved (saddle-shaped).
