Real-time 2D to 3D video conversion unveiled

October 8, 2002

New $99 software that converts standard two-dimensional video images into three-dimensional viewing in real time has been unveiled.

The PC-based system requires users to wear special glasses. The technology creates the illusion of depth by generating two images out of one, each tilted and distorted to generate the illusion of depth when combined.

A chip for TV sets is expected in 2003.

Scientists discover magnetic superatoms

June 16, 2009

A “magnetic superatom” — a stable cluster of atoms that can mimic different elements of the periodic table and that one day may have applications in spintronics (using electron spin for memory and data processing) — has been discovered by Virginia Commonwealth University scientists.

Tool Use Is Just a Trick of the Mind

January 30, 2008

A new study in monkeys by University of Parma scientists suggests that the brain’s trick in learning to use tools is to treat tools as just another body part.

3D model for lung cancer mimics the real thing

October 12, 2012

Using a new technique that allows scientists to grow lung cancer cells in three dimensions, researchers at The Methodist Hospital and the University of Texas MD Anderson Cancer Center have created a model that uses biological matter to form miniature lungs that mimic the structure and function of real lung cancer, after which human lung cancer cells are added.

The model could accelerate discoveries for a type of cancer that has benefited… read more

New Google ‘Evangelist’ to Spread Applications

September 9, 2005

Google has hired Internet pioneer Dr. Vinton G. Cerf as “chief Internet evangelist.”

“The Internet has a billion users, and we have 5.6 billion to go,” Dr. Cerf said. “Each will come to the Internet in different ways, like wirelessly, and Google needs to be receptive and adaptive to those different circumstances.”

Sensors Gone Wild

October 27, 2002

The real goal of a $40 million experiment is to explore the uses of intelligent sensors, a technology whose promise suddenly seems huge. The applications for this “embedded intelligence” are vast and profound. Eventually large swaths of the earth will communicate with the digital realm using millions of miniature sensors. Sensors will be placed in bridges to detect and warn of structural weakness and in water reservoirs to spot hazardous… read more

Bird navigation breaks entanglement record

June 23, 2009

An electron pair generated in bird eyes during navigation using the Earth’s magnetic field could be entangled for at least 100 microseconds, suggest University of Oxford researchers.

Bio-crude turns cheap waste into valuable fuel

February 5, 2008

CSIRO and Monash University have developed a chemical process that turns green waste into a stable bio-crude oil usable for producing high- value chemicals and biofuels, including both gasoline and diesel replacement fuels.

The process uses low-value waste such as forest thinnings, crop residues, waste paper and garden waste, significant amounts of which are currently dumped in landfill or burned.

Tiny microscope peers into mice brains

September 21, 2005

A microscope the size of a matchbox can image blood vessels lying 1 millimeter below the surface of the brains of mice, with a resolution of 1 micrometer.

A pin-like probe, 1 mm in diameter, protrudes from the bottom of the device and punches a tiny hole in the head of the anesthetized mouse. The probe does not enter the brain, but sits on top of the hippocampus. There… read more

Quantum Entanglement Observed by Naked Eye

May 5, 2011

CHSH-Bell test

Quantum entanglement — when two particles become linked so that measurements performed on one affect the other — has now been observed on a scale visible to the naked human eye.

Physicist Nicolas Gisin of the University of Geneva entangled two photons, then amplified one of them by having it trigger the release of thousands of other photons, each with the same polarization… read more

Nanowires within nanowires

November 13, 2002

Harvard University researchers have synthesized nanowires that are only 50nm in diameter, containing a germanium core surrounded by a silicon shell. They also made “triple decker” wires of silicon, silicon oxide and germanium.

They have used these approaches to prepare new devices called nanowire field-effect transistors. Working with researchers from Intel, the team also plans to integrate these transistors with conventional semiconductor processing to produce advanced hybrid devices.

Carbon Ring Storage Could Make Magnetic Memory 1,000 Times More Dense

June 30, 2009

A method of improving storage density by three orders of magnitude using cobalt dimers on hexagonal carbon rings has been developed by researchers at Leibniz Institute for Solid State and Materials Research.

Biofuels Are Bad for Feeding People and Combating Climate Change

February 8, 2008

Converting corn to ethanol in Iowa not only leads to clearing more of the Amazonian rainforest, researchers report, but also would do little to slow global warming.

It may often make it worse. Growing plants store carbon in their roots, shoots and leaves, which will end up as carbon dioxide in the atmosphere when cut down. And diverting food crops into fuel production also leads to ever more land… read more

Help for Info Age Have-Nots

October 3, 2005

To bridge the Digital Divide, MIT and companies like AMD, Motorola, and Yahoo are pushing devices and services aimed at bringing cutting-edge tech to parts of the world that need it most.

Ford, Google team up to make smarter cars

May 12, 2011

Ford API

Ford is joining Google in using Google’s Prediction API to create cars that determine where you’re going by examining where you’ve been.

A computer in your car would create an encrypted record of your driving data — where, when, and what route — and tailor the car to your driving profile. Eventually, your car “remembers” where and how you drive. It would then optimize itself for the trip to… read more
