Space mirrors could create Earth-like haven on Mars

November 14, 2006

Mirrors in orbit around Mars could be used for “terraforming,” creating Earth-like conditions on a small patch of the planet’s surface, according to a NASA-funded study.

The extra sunlight would provide warmth and solar power for human explorers.

Wearable instrument shirt allows for playing air guitar

November 14, 2006

Australia’s scientific research agency, CSIRO, has created a “wearable instrument shirt” (WIS) that enables users to play an “air guitar” simply by moving one arm to pick chords and the other to strum the imaginary instrument’s strings.

Textile motion sensors embedded in the shirt sleeves detect arm motion and relay it wirelessly to a computer. Custom software then maps motion data to audio samples. The technology is adaptable to… read more

A Step Closer to Nanotube Computers

November 14, 2006

Stanford University researchers have developed a method of separating out purely semiconducting nanotubes with a consistent range of diameters stretching across the source and drain.

The method is scalable to a bulk manufacturing process.

New Top 500 supercomputer sites list

November 14, 2006

The 28th TOP500 List of supercomputer sites for 2006 has been released.

IBM BlueGene/L system, installed at DOE’s Lawrence Livermore National Laboratory, retains the No. 1 spot with a Linpack performance of 280.6 teraflops (trillions of calculations per second, or Tflop/s).

The new No. 2 systems is Sandia National Laboratories’ Cray Red Storm supercomputer, only the second system ever to be recorded to exceed the 100… read more

Space elevators: ‘First floor, deadly radiation!’

November 14, 2006

Humans might not survive the trip on space elevators, thanks to the ionizing radiation they would receive travelling through the core of the Van Allen radiation belts around Earth.

Electron beams shrink carbon nanotubes to order

November 14, 2006

A way to controllably shrink carbon nanotubes to a particular diameter could someday help electronics engineers build faster computers and other novel electronic devices.

An electron beam is fired at the tube to knock carbon atoms out of their honeycomb structure while a current is run through the tube to reshuffle the remaining carbon atoms back into a regular, albeit narrower, nanotube structure.

Natural-born painkiller found in human saliva

November 13, 2006

Saliva from humans has yielded a natural painkiller up to six times more powerful than morphine, researchers say.

The substance, dubbed opiorphin, may spawn a new generation of natural painkillers that relieve pain as well as morphine but without its addictive and psychological side effects.

IBM’s chief steps into ‘Second Life’ for incubator launch

November 13, 2006

IBM’s CEO Sam Palmisano is set to launch a $100 million investment Tuesday to incubate new businesses–and he will make the announcement in both the physical and virtual worlds, via a “town hall” meeting in Beijing and in the Second Life virtual world.

Palmisano’s avatar will discuss the announcement in Second Life’s Forbidden City, a space created in the virtual environment by IBM and the Chinese government.

Comprehensive model is first to map protein folding at atomic level

November 12, 2006

Scientists at Harvard University have developed a computer model that can fully map and predict protein folding for some 10 microseconds — about as long as some proteins take to assume their biologically stable configuration, and at least a thousand times longer than previous methods.

“This appears to have achieved a holy grail: simulating and predicting protein folding from a linear amino acid sequence,” said Ray Kurzweil. “It is… read more

Entrepreneurs See a Web Guided by Common Sense

November 12, 2006

Computer scientists are finding new ways to mine human intelligence.

Their goal is to create Web 3.0, or the “semantic Web,” by adding a layer of meaning on top of the existing Web that would make it less of a catalog and more of a guide — and even provide the foundation for systems that can reason in a human fashion.

Radar Networks, for example, is one of… read more

Doctors using Google to diagnose illnesses

November 12, 2006

In a test of difficult diagnostic cases published in the New England Journal of Medicine last year, Google searches found the correct diagnosis in 58 per cent of the cases, including obscure conditions such as Cushing’s syndrome and Creutzfeldt-Jakob disease.

Studies of autopsies have shown doctors seriously misdiagnose fatal illnesses about 20 per cent of the time.

Cheap, Superefficient Solar

November 9, 2006

Technologies collectively known as concentrating photovoltaics are starting to enjoy their day in the sun, thanks to advances in solar cells, which absorb light and convert it into electricity, and the mirror- or lens-based concentrator systems that focus light on them. The technology could soon make solar power as cheap as electricity from the grid.

Kurzweil keynotes Cleveland Clinic 2006 Medical Innovation Summit

November 9, 2006

Ray Kurzweil presented a keynote talk at the Cleveland Clinic 2006 Medical Innovation Summit on November 6.

The conference highlighted new technologies, economics and trends in the neurosciences. His keynote on “future technology” featured a dialogue with Allen Roses, M.D., Senior Vice President, Genetics Research, GlaxoSmithKline, moderated by Thomas Stewart, Editor of the Harvard Business Review.

HPNA gets speed boost to 320Mbps

November 9, 2006

The HomePNA Alliance has released a new networking standard that allows for 320Mbps transmission over twisted-pair copper wire or coaxial cable in the home.

Retinal Transplant Restores Vision in Mice

November 9, 2006

The prospect of restoring vision in people who have been blinded by disease is now on the verge of being a real possibility, thanks to the first successful transplant of light-sensitive retinal cells in mice.

The researchers harvested stem cells that were in the process of turning into light-sensitive photoreceptor cells and implanted them in the eyes of mice that had been bred to suffer from retinal… read more
