New carbon nanotube technology to reduce large-scale emissions

September 19, 2007

A novel technology to trap large-scale greenhouse gas emissions is being developed by University of Queensland researcher Dr. John Zhu.

He aims to develop a carbon nanotube membrane for gas separation that will work like a sieve to separate high volumes of methane or carbon dioxide from other gases. The methane could also be used to provide valuable pipeline-quality gas.

Dr Zhu said that the CNT technology would… read more

$100 Genome

February 27, 2009

BioNanomatrix is pursuing what may be the key to personalized medicine: sequencing technology so fast and cheap that an entire human genome can be read in eight hours for $100 or less.

Nanotech’s dark side debated

November 5, 2001

In light of the terrorist attacks of Sept. 11 and anthrax headlines, it’s not hard for some to imagine a nightmare scenario involving a new generation of terrorists able to obtain infinitely more powerful nanoweapons.
As nanotech makes the transition from the drawing board to reality, every development brings the fledgling industry closer to the day when many believe government regulations and secrecy will be needed to prevent abuses.… read more

Graphene nanoribbons enable quantum switches

March 22, 2011

A new “templated growth” technique for fabricating nanoribbons of epitaxial graphene has produced structures just 15 to 40 nanometers wide that conduct current with almost no resistance, says Walt de Heer, a professor in the School of Physics at the Georgia Institute of Technology.

The graphene nanoribbons are being used to develop high-frequency transistors — perhaps even at the terahertz range — and lower power… read more

Google testing “My World” for launch later this year

September 26, 2007

Rumors of Google’s plans to create a virtual world that rivals that of Second Life have popped up once again.

It would be a 3D social network tied into Google’s current applications of Google Earth and Google Maps.

A virtual world is a natural progression of Google Earth. Users could create avatars. The “street view” feature of Google Maps could be incorporated, as well as Google SketchUp, with… read more

Researchers: Metcalfe’s Law overshoots the mark

March 15, 2005

Andrew Odlyzko and Benjamin Tilly of the University of Minnesota have written a paper arguing that Metcalfe’s Law, a rule of thumb that computes the value of communication networks, is overly optimistic.

“The fundamental fallacy underlying Metcalfe’s (Law) is in the assumption that all connections or all groups are equally valuable,” the researchers report.

The researchers propose a less dramatic rule of thumb: the value of… read more

Shocking cancer treatment may also yield weapon

March 5, 2009

A technique using 60-nanosecond pulses thought to be a promising cancer treatment is also being investigated by Old Dominion University as the basis for a Taser-like weapon that stuns for longer.

Scientists raise spectre of gene-modified athletes

November 30, 2001

We may be watching genetically-modified (GM) athletes as soon as the Beijing Olympics in 2008, researchers say. Gene doping, in which athletes could genetically modify themselves with performance-enhancing DNA, will be almost impossible to detect, according to Peter Schjerling at the Copenhagen Muscle Research Centre in Denmark.
Schjerling believes cheats will avoid detection by injecting themselves with copies of genes naturally present in the body, such as those encoding growth… read more

50 Years Later, a New ‘Sputnik’ Crisis: The War of Minds

October 5, 2007

The American education system is not mobilizing to support science, technology, engineering and math.

Today’s generation of kids is the most technology savvy group that this country has ever produced. They are born with an iPod in one hand and a cell phone in another. They’re text messaging, e-mailing, instant messaging. They’re on MySpace, YouTube & Google. They’ve got Nintendo Wiis, Game Boys, Play Stations.

Their world is… read more

New look for nanomotors

March 23, 2005

Physicists in the US have built the first nanoelectromechanical device that exploits the effects of surface tension.

The “relaxation oscillator” consists of two droplets of liquid metal on a substrate made of carbon nanotubes and can be controlled with a small applied electric field. Alex Zettl and colleagues at the University of California at Berkeley and the Lawrence Berkeley National Laboratory say the device could find use in various… read more

The University of Manchester’s Jodrell Bank Observatory has been chosen as the headquarters for a $2 billion effort to build the world’s largest and most sensitive radio telescope, the Square Kilometre Array (SKA).

The SKA will be capable of answering some of the most fundamental questions about the Universe, including dark energy, how the first stars and galaxies formed after the Big Bang, how galaxies… read more
