Renewing a Call to Act Against Climate Change

March 14, 2007

Bill McKibben, who was one of the first laymen to warn of global warming, is now the philosopher-impresario of the program of climate-change rallies called Step It Up.

Start-Up Fervor Shifts to Energy in Silicon Valley

March 14, 2007

Silicon Valley’s dot-com era may be giving way to the watt-com era. Out of the ashes of the Internet bust, many technology veterans have regrouped and found a new mission in alternative energy: developing wind power, solar panels, ethanol plants and hydrogen-powered cars.

Invisible Revolution

March 14, 2007

Artificially structured metamaterials could transform telecommunications, data storage, and even solar energy.

New 3D ‘flyovers’ let viewers swoop down on Mars

March 14, 2007

Dramatic virtual flyovers of NASA’s two Mars rover landing sites have been made using 3D imagery from the agency’s Mars Reconnaissance Orbiter (MRO). The flyovers give a first taste of the probe’s astoundingly precise 3D mapping abilities and may help the Opportunity rover find a safe path into the yawning chasm of Victoria crater.

Nanowires in the blood could feel the pressure

March 14, 2007

Nanowires that produce a current during bending could one day be implanted into the body to monitor changes in blood pressure, Georgia Institute of Technology researchers claim.

Yacht voyage yields array of new genes

March 14, 2007

A yacht voyage that genome pioneer Craig Venter took around the world has turned up a startling array of new genes and new gene families.

They have found genes that help microbes use the sun’s energy in new ways, genes that help them use nitrogen, and genes that protect organisms from ultraviolet light, and have identified more than 6 million new proteins.

Robot that roams the body to seek and destroy cancer

March 14, 2007

An insect-shaped robot could be a major weapon in the fight against cancer.

The device, just under an inch long, is designed to be inserted into the body through a small incision. Once inside, doctors can control its movements and direct it to areas where investigations are needed.

The robot measures 2cm in length by 1cm in diameter and can deliver drugs, collect data and treat affected body… read more

A Smarter Web

March 13, 2007

New technologies will make online search more intelligent–and may even lead to a “Web 3.0.”

Study Says Computers Give Big Boosts to Productivity

March 13, 2007

Money spent on computing technology delivers gains in worker productivity that are three to five times those of other investments, according to a study being published today. But the study also concluded that the information technology industry itself was unlikely to be a big source of new jobs.

From a Rapt Audience, a Call to Cool the Hype

March 13, 2007

Some scientists argue that some of Al Gore’s central points are exaggerated and erroneous. They are alarmed, some say, at what they call his alarmism.

Scientists threatened for ‘climate denial’

March 13, 2007

Scientists who questioned mankind’s impact on climate change have received death threats and claim to have been shunned by the scientific community.

They say the debate on global warming has been “hijacked” by a powerful alliance of politicians, scientists and environmentalists who have stifled all questioning about the true environmental impact of carbon dioxide emissions.

Richard Lindzen, professor of Atmospheric Science at Massachusetts Institute of Technology recently claimed:… read more

Neuron Control

March 13, 2007

A coalition of big technology companies wants to bring high-speed Internet access to consumers by allowing idle TV channels, known as white space, to be used to beam the Internet into homes and offices.

TR10: Neuron Control

March 13, 2007

Karl Deisseroth’s genetically engineered “light switch,” which lets scientists turn selected parts of the brain on and off, may help improve treatments for depression and other disorders.

Is the universe a fractal?

March 13, 2007

Written across the sky is a secret, a hidden blueprint detailing the original design of the universe itself.

The spread of matter throughout space follows a pattern laid out at the beginning of time and scaled up to incredible proportions by nearly 14 billion years of cosmic expansion. Today that pattern is gradually being decoded by analyzing maps of the distribution of the stars, and what has been uncovered… read more

Animation tool puts you in the frame, or the game

March 13, 2007

A 3D animation technique that could take the hard work out of acting has been developed by German researchers.

It allows for directly animating 3D laser scans of people, using the motion of another individual collected using motion capture or using the pre-programmed motion of another character.
