Gulf between rich, poor will grow if nanotech opponents prevail

January 28, 2004

The chasm between have and have-not countries will grow even wider if nanotechnology research is blocked by the unbalanced positions of high-profile opponents like Prince Charles, warns a new analysis from a leading global medical ethics think tank.

In an article to be published by the Institute of Physics’ journal “Nanotechnology,” and released Jan. 28 online at Nanotechweb.org, the authors say the potential health, environmental and economic… read more

The Need for Speed on the Web

May 11, 2010

Aptimize, a startup based in Wellington, New Zealand, that launches its service for websites in the United States today, says its software can speed up website load times, bringing increases of 200 to 400 percent in some cases.

The software gets into the middle of the normally sluggish page-processing pipeline and makes it more efficient. It combines resources so they only have to be downloaded once. For example, it… read more

Pluggd: A Google for Podcasts

December 21, 2006

Pluggd has found a way to index podcasts, talk shows and other spoken-word content. The company’s service then allows users to search the audio files for specific words, which are spoken in context by the original speaker.

Two-egg diet cracks cholesterol issue

August 29, 2008

University of Surrey researchers have found that people who ate two eggs per day, while on a calorie-restricted diet, lost weight and reduced their blood cholesterol levels.

The Computer at Nature’s Core

February 10, 2004

The computational worldview — that the universe itself is governed by the laws of computation and is, in fact, a computer — is the death of the notion that technology is applied science.

If both the physical universe and the biological world are best understood in terms of information and computation, it no longer makes sense to think that technology results from an application of science. Indeed, if computation… read more

Giving new meaning to ‘smart car’

May 18, 2010

McMaster and IBM are investigating how the automotive industry can connect a vehicle’s multiple sensors and microprocessors in the vehicle and on roads to create a “cognitive car” that can predict vehicle failures before they happen, redirect drivers to less congested routes and help reduce traffic accidents, and give drivers real-time visual information and alerts.

The program will also study how increased computing power can help vehicles better integrate… read more

Cows Engineered to Lack Mad Cow Disease

January 2, 2007

Scientists have genetically engineered a dozen cows to be free from the proteins that cause mad cow disease, a breakthrough that may make the animals immune to the brain-wasting disease.

Fatal protein interactions may explain neurological diseases

September 4, 2008

University of California, San Diego, and San Diego Supercomputer Center (SDSC) researchers have investigated how proteins involved in neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease interact to form unique complexes.

Their findings explain why Alzheimer’s patients might develop Parkinson’s, and vice versa. The new and unique molecular structures they discovered can now be used to model and develop new drugs for these devastating neurological diseases.

Scientists Say Administration Distorts Facts

February 19, 2004

More than 60 influential scientists, including 20 Nobel laureates, issued a statement yesterday asserting that the Bush administration had systematically distorted scientific fact in the service of policy goals on the environment, health, biomedical research and nuclear weaponry at home and abroad.

According to the report, the Bush administration has misrepresented scientific consensus on global warming, censored at least one report on climate change, manipulated scientific findings on the… read more

LiveMatrix Launches

May 26, 2010

LiveMatrix, just launched, tracks live events on the Web, including streaming video, auctions, sales, and competitions.

By providing a listing for the Web that resembles TV timetables, the company hopes to “make the time dimension of the Web searchable,” according to cofounder Nova Spivack.

Laser-induced explosion of gold nanoparticles: potential role for nanophotothermolysis of cancer

January 12, 2007

Researchers have used laser-induced explosion of absorbing nanoparticles in selective nanophotothermolysis of cancer.

This is realized through fast overheating of a strongly absorbing target during a short laser pulse. The resulting explosion of nanoparticles may be accompanied by optical plasma and shock waves with supersonic expansion and particle fragmentation with fragments of high kinetic energy. These can contribute to the killing of cancer cells.

Call to Arms for an American-Led Green Revolution

September 10, 2008

Thomas L. Friedman’s latest book, “Hot, Flat, and Crowded,” is a plea for a new Sputnik movement that will inspire a green revolution to counter global environmental disaster.

NASA to Announce ‘Significant Findings’ of Water on Mars Tuesday

March 2, 2004

NASA will hold a press conference Tuesday at 2 P.M. ET to announce “significant findings” about water on Mars based on evidence from its Opportunity Mars rover.

If there is liquid water presently at the surface of Mars, as several lines of rover evidence have hinted, then most scientists agree there is the possibility that life could exist.

Exploring Music’s Hold on the Mind

June 2, 2010

“When the language part of the brain has been damaged, you can sometimes recruit the part that processes music to take over,” says neuroscientist Aniruddh D. Patel, author of “Music, Language, and the Brain.”

“Music neuroscience is also helping us understand Alzheimer’s. There are Alzheimer’s patients who cannot remember their spouse. But they can remember every word of a song they learned as a kid. By studying this, we’re… read more

‘Heat mining’ could be key U.S. energy source

January 23, 2007

A comprehensive new MIT-led study of the potential for geothermal energy within the United States has found that mining the huge amounts of heat that reside as stored thermal energy in the Earth’s hard rock crust could supply a substantial portion of the electricity the United States will need in the future, probably at competitive prices and with minimal environmental impact.

The study shows that drilling several… read more
