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

Lab-on-Chip Detects, Identifies Specific Malarial Strains

May 5, 2009

University of Glasgow have developed a lab-on-chip device that takes one hour to identify what strain of malaria a patient has, allowing doctors to know if the particular infection can be treated with available medications.

Currently it can take up to 48 hours to determine whether a patient has Malaria and even then, doctors are unable to tell whether the parasite is drug-resistant.

Protocols needed to deal with health effects from disasters

April 7, 2011

Researchers at LSU Health Sciences Center New Orleans School of Medicine have called for the urgent development of protocols to deal with the health effects of disasters.

They point out that the magnitude of the impact of the Deepwater Horizon Gulf Oil Spill on human health, the environment, and the economy remains unknown. Their study assesses the known toxicologic consequences of oil spill exposures, but… 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.

Giving Avatars Real Bodies

December 18, 2007

Korea Advanced Institute of Science and Technology scientists have developed a system for controlling physical robots using software robots, displayed as virtual-reality avatars.

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

Color E-Paper That Rivals the Real Thing

Prototype in-plane electrophoretic display (Philips)

A new approach to electrophoretic displays being developed by Philips Research — moving pixels horizontally instead of vertically — may finally mean high-quality color electronic paper.

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.

Scientists find new way to sort stem cells

December 21, 2007

UC Irvine scientists have found a new way to sort stem cells that should be quicker, easier and more cost-effective than current methods.

The technique could in the future expedite therapies for people with conditions ranging from brain and spinal cord damage to Alzheimer’s and Parkinson’s 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

City 2.0: Using tech building blocks in tomorrow’s urban centers

May 18, 2009

Highly connected cities with smart grids, widely available wireless access, social networks, and sustainable data centers are well within reach.

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.

Regenerating Nerves

January 2, 2008

Georgia Institute of Technology researchers have triggered the regrowth of neurites (neurons’ information-carrying projections), using a polymer coated with chemical structures that resemble acetylcholine, a common neurotransmitter.

The research could one day lead to treatments for neurodegenerative diseases and spinal-cord injuries.

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.

How to draw a chemical sensor with carbon-nanotube ‘pencil lead’

October 10, 2012

drawing-nanotubes-mit

New low-cost, durable carbon nanotube sensors can be etched with mechanical pencils.

The methods typically used to fabricate carbon nanotube sensors are hazardous and not suited for large-scale production. But a new  method created by MIT chemists — as simple to use as drawing a line on a sheet of paper — may overcome that obstacle.

MIT postdoc Katherine Mirica has designed a new type… read more
