Super-Eruptions Pose Global Threat ’5-10 Times More Likely Than Asteroid Impact’

April 27, 2005

A volcanic super-eruption would have severe environmental effects and might threaten global civilization. This is the assessment of a Geological Society of London working group composed of senior Earth Scientists.

Trapping atoms for quantum computing

April 26, 2005

Ohio State University scientists have taken a step toward the development of quantum computers by making tiny holes in an egg carton-shaped surface of laser light that could one day cradle atoms.

They’ve been able to form about a billion gaseous rubidium atoms into a pea-sized cloud with magnetic fields. Now they are working to move that cloud into position above a chip supporting an optical lattice formed where… read more

The Next Wave of Disruptive Technologies

April 26, 2005

The semantic Web, autonomous agents, sensor networks, and RFID are among the emerging technologies that will radically change the future of manufacturing.

Staying Out in Front

April 25, 2005

A published road map for the semiconductor industry has the smallest distances between wires on a memory chip shrinking from 90 nanometers today to 65nm in 2007, to 45nm in 2010, to 32nm in 2013 and on down from there.

HP hopes to apply some of its research ideas toward the 32nm milestone. The idea isn’t to replace silicon transistors but to build certain devices, such as ultradense memories,… read more

In Small Trial, Gene Therapy Is Seen as Aid in Alzheimer’s

April 25, 2005

A small clinical trial has produced preliminary evidence that gene therapy may slow the decline in mental functioning associated with Alzheimer’s disease.

The gene involved in this trial controls production of nerve growth factor, a protein that can protect brain cells from death.

Microbial fuel cell: High-yield hydrogen source and wastewater cleaner

April 25, 2005

Using a new electrically-assisted microbial fuel cell (MFC) that does not require oxygen, researchers at Penn State and Ion Power Inc. have developed the first process that enables bacteria to coax four times as much hydrogen directly out of biomass than can be generated typically by fermentation alone.

“This form of renewable energy production may help offset the substantial costs of wastewater treatment as well as provide a contribution… read more

Improved Scanning Technique Uses Brain as Portal to Thought

April 25, 2005

An improved functional magnetic resonance imaging technique has enabled scientists to figure out what people are looking at — even, in some cases, when they are not aware of what they have seen.

‘Info-mania’ dents IQ more than marijuana

April 25, 2005

Far from boosting productivity, the constant flow of emails, cellphone calls and instant messages received by modern workers can seriously reduce a person’s ability to focus on tasks, a study of office workers found.

Mess with the body clock at your peril

April 25, 2005

Workers with irregular sleep patterns have a higher risk of heart disease and diabetes and are more tired and inattentive, increasing the chance of accidents and mistakes.

Superlens opens door to nanoscale optical imaging, high-density optoelectronics

April 21, 2005

Scientists at the University of California, Berkeley have developed a “superlens” that can break the so-called diffraction limit of optics through negative refraction, allowing for imaging of 60-nanometer objects.

Nanoswitch uses organic molecules

April 21, 2005

Weizmann Institute of Science have demonstrated a new kind of electrical switch, formed of organic molecules, that could be used in the future in nanoscale electronic components.

The Infinite Library

April 21, 2005

Google is converting the full text of millions of library books into searchable Web pages. How will libraries function in 2020 or 2050, once Google or its successors have finished digitizing the world’s printed knowledge?

Stink bomb gas puts mice into suspended animation

April 21, 2005

Suspended animation has been deliberately induced in a species of mouse which does not naturally hibernate, using hydrogen sulphide.

If a similar response could be triggered in humans, there would be major healthcare benefits and the futuristic idea of putting astronauts into suspended animation on long-haul space flights could move a step closer to reality.

Nanomagnets bend the rules

April 21, 2005

Scientists at the National Institute of Standards and Technology (NIST) and Brookhaven National Laboratory have found that a class of nanostructured materials that are key components of computer memories and other important technologies undergo a previously unrecognized shift in the rate at which magnetization changes at low temperatures.

The results could point the way to marked improvements in the performance of microwave devices.

Gene discovered that plays a key role in brain wiring

April 21, 2005

A team headed by Drs. Robin Hiesinger and Hugo J. Bellen at Baylor College of Medicine in Houston has found a gene, named sec15, that plays a key role in brain wiring.
