Backpack generates a powerful punch

September 9, 2005

A backpack that generates electricity as its wearer walks generates up to 7 watts, more than enough to power cellphones or other devices, while reducing backpack load forces on walkers.

Brain May Still Be Evolving, Studies Hint

September 9, 2005

Two genes, microcephalin and ASPM, involved in determining the size of the human brain have undergone substantial evolution in the last 60,000 years, researchers say, leading to the surprising suggestion that the brain is still undergoing rapid evolution.

New Google ‘Evangelist’ to Spread Applications

September 9, 2005

Google has hired Internet pioneer Dr. Vinton G. Cerf as “chief Internet evangelist.”

“The Internet has a billion users, and we have 5.6 billion to go,” Dr. Cerf said. “Each will come to the Internet in different ways, like wirelessly, and Google needs to be receptive and adaptive to those different circumstances.”

Molecules used as information processors

September 8, 2005

Chemists at Queen’s University Belfast are exploring the capabilities of molecules that act like conventional computers but in spaces only a few nanometers across.

Molecular information processors placed in nano-spaces can gather, process and supply valuable data on how chemistry and biology function at this tiny scale. Molecules can also be used as information processors in medical and other applications.

Nanotech researchers build brawny molecules

September 8, 2005

A breakthrough in nanotechnology could hasten the development of molecular machines that can act as artificial muscles or drug delivery systems in the body.

Chemists at Edinburgh University used ultraviolet light to stimulate human-made molecules to propel small droplets of liquid across flat and sloped surfaces.

The achievement, according to the researchers, is equivalent to a conventional machine lifting an object to more than twice the height of… read more

Nuclear stockpiles could create 300,000 bombs

September 8, 2005

The world has made enough explosives for more than 300,000 nuclear bombs, according to the latest scientific assessment of countries’ nuclear stockpiles.

Experts are worried that terrorists could steal enough to trigger a nuclear catastrophe.

Odd behavior and creativity may go hand-in-hand

September 7, 2005

New research on individuals with schizotypal personalities — people characterized by odd behavior and language but who are not psychotic or schizophrenic — offers the first neurological evidence that they are more creative than either normal or fully schizophrenic individuals, and rely more heavily on the right sides of their brains than the general population to access their creativity.

Deceit of the Raven

September 7, 2005

Science is chipping away at the case for human uniqueness, showing that animals and machines are more like us than we believed.

What happens, as these trends continue, to the familiar guideposts for deciding what is human?

Safecrackers open up the “deep Web”

September 7, 2005

Glenbrook Networks says it has a way to tunnel far into the “deep Web” and extract Web pages that are largely unreachable by most search engines because they are stored in databases that Web crawlers can’t access.

High Doses Of Vitamin E Boost Rat Survival Rate 40%; Brain Function, Neuromuscular Gains

September 7, 2005

Mice given high doses of vitamin E showed a 40% increase in median lifespan and increases in the ability to perform tests measuring neuromuscular performance and cognitive exploratory activity.

The results support the “free radical” theory of aging.

Sonic ‘Lasers’ Head to Flood Zone

September 5, 2005

Prototypes of non-lethal sonic devices have been demonstated to military and law enforcement.

The Magnetic Acoustic Device, or MAD, can beam audible sounds a mile away, to replace conventional public address systems; at closer range, they can be used for crowd control.

Parasites brainwash grasshoppers into death dive

September 5, 2005

A parasitic worm that makes the grasshopper it invades jump into water and commit suicide does so by producing proteins which directly and indirectly affect the grasshopper’s central nervous system.

Some of the proteins were linked to neurotransmitter activities. Others were linked to geotactic behaviour — the oriented movement of an organism in response to gravity.

Diamond-nanotube nanocomposite developed

September 5, 2005

Researchers at the U.S. Department of Energy’s Argonne National Laboratory have combined the world’s hardest known material — diamond — with the world’s strongest structural form — carbon nanotubes.

The resulting material has potential for use in low-friction, wear-resistant coatings, catalyst supports for fuel cells, high-voltage electronics, low-power/high-bandwidth radio frequency MEMS/NEMS, thermionic energy generation, low-energy-consumption flat panel displays, and hydrogen storage.

The new hybrid material was created using… read more

4G prototypes reach blistering speeds

September 5, 2005

Cellphones capable of transmitting data at a gigabit per second have been demonstrated by NTT DoCoMo in Japan.

In experiments, prototype phones were used to view 32 high definition video streams, while travelling in an automobile at 20 kilometers per hour.

Multiple-input-multiple-output (MIMO) multiplexing was also used to send data via various routes across a network to further increase data capacity.

Dark matter highlights extra dimensions

September 5, 2005

University of Oxford scientists say extra spatial dimensions can be inferred from the perplexing behavior of dark matter, which behaves differently in small galaxies and large clusters of galaxies.

Three extra dimensions are altering the effects of gravity over very short distances of about a nanometer, they speculate, implying that the Universe is only about a nanometer wide in these three “directions.”
