Revolutionary auto already on the road

November 10, 2008

Inventor Dean Kamen has developed the world’s first Stirling hybrid electric car, using a Stirling engine to powers the features that would normally drain huge power from the battery (defroster and heater), and can go about 60 miles on a single charge of its lithium battery, with practically zero emissions.

Graphene transistors have a nanoscale cooling effect

April 4, 2011

Graphene Contact

Researchers at the University of Illinois have found that graphene transistors have a nanoscale cooling effect that reduces their temperature.

The Illinois team used an atomic force microscope (AFM) tip as a temperature probe to make the first nanometer-scale temperature measurements of a working graphene transistor.

They found that thermoelectric cooling effects can be stronger at graphene contacts than resistive heating, actually lowering the temperature… read more

Doctors Change the Way They Think About Death

May 2, 2007

Standard emergency-room procedure has it backward, says Dr. Lance Becker, director of the University of Pennsylvania Center for Resuscitation Science: blood-starved heart muscle is suddenly flooded with oxygen, precisely the situation that leads to cell death.

Instead, Becker says, we should aim to reduce oxygen uptake, slow metabolism and adjust the blood chemistry for gradual and safe reperfusion.

Motorola rolls out Wi-Fi phone

July 27, 2004

Motorola has introduced a new phone that it says will switch calls seamlessly between cellular services and wireless WiFi Internet networks, potentially offering big savings for customers.

It is planned to be commercially available by fall or early 2005,

Telescoping Carbon Nanotubes Can Make Flash Memory Replacment

November 14, 2008

Researchers at The University of Nottingham have used carbon nanotubes to make fast non-volatile memory.

India’s elephant in the room: Weak patent laws

May 10, 2007

India’s fast-growing biotech business has the potential to be one of the driving forces behind its enviable 8 percent GDP growth, and a government estimate sees the industry increasing 15-fold over the next eight years.

Mapping the Physical And Mental Universes

August 5, 2004

If the manual of life is encoded in our DNA, where do we look to find the blueprint of consciousness? This was a subject that fascinated Francis Crick, who, along with James Watson, discovered the double-helix structure of DNA 50 years ago.

Engrossed in the mysterious relationship between mind and body, Crick later felt impelled to turn his attention from matter to mind and from biology to philosophy –… read more

New theory of visual computation reveals how brain makes sense of natural scenes

November 20, 2008

Computational neuroscientists at Carnegie Mellon University have developed a computational model that provides insight into the function of the brain’s visual cortex and the information processing that enables people to perceive contours and surfaces, and understand what they see in the world around them.

The model employs an algorithm that analyzes the myriad patterns that compose natural scenes and statistically characterizes those patterns to determine which patterns are most… read more

Google’s goal to organise your daily life

May 23, 2007

Google envisages a day when it can tell people what jobs to take and how they might spend their days off, says CEO Eric Schmidt.

The race to accumulate the most comprehensive database of individual information has become the new battleground for search engines, to enable personalized ads, which would command higher rates.

Artificial Retina

August 19, 2004

A retinal prosthesise implanted in the eye could restore the sight of millions.

It would use a digital video camera mounted on a pair of glasses, coupled via a miniature transmitter to a retinal implant array underneath the retina. The array’s electrodes would stimulate surviving nerve cells in response to images from the camera, providing a small patch of vision.

The Boston Retinal Implant Project hopes to test… read more

A closed Android-based network to study cyber disruptions and help secure hand-held devices

October 4, 2012

Sandia builds self-contained, Android-based network to study cyber disruptions and help secure hand-held devices

As part of ongoing research to help prevent and mitigate disruptions to computer networks on the Internet, researchers at Sandia National Laboratories in California have turned their attention to smartphones and other hand-held computing devices.

Sandia cyber researchers linked together 300,000 virtual hand-held computing devices running the Android operating system so they could study large networks of smartphones and find ways to make them more reliable and… read more

Brain works better with neurological disease

November 26, 2008

Huntington’s disease improves ability at some cognitive tests, possibly because neurons become abnormally sensitive to the neurotransmitter glutamate, which is vital for sensory discrimination.

The finding by the Leibniz Research Centre for Working Environment and Human Factors in Germany strengthens the glutamate theory and suggests that the cognitive tasks be used as a test for drugs that block the glutamate response.

Genome of DNA Pioneer Is Deciphered

June 1, 2007

The full genome of James D. Watson, one of the discoverers of the structure of DNA in 1953, has been deciphered, marking what some scientists believe is the gateway to an impending era of personalized genomic medicine.

J. Craig Venter, who as president of the Celera Corporation started a human genome project in competition with the government, has brought his genome to completion at his own institute in Rockville,… read more

Eating Radiation: A New Form of Energy?

June 4, 2007

In a bizarre alternative to photosynthesis, some fungi transform radiation into energy to use as food for growth–with the role of chlorophyll taken by melanin, a chemical also found in human skin.

The fungi might be used as a biofuel to be grown in high-altitude regions.

Mysterious signals from 1000 light years away

September 2, 2004

A radio signal designated “SHGb02+14a” seems to be coming from a point between the constellations Pisces and Aries, where there is no obvious star or planetary system within 1000 light years. And the transmission is very weak.

It has a frequency of about 1420 megahertz (one of the main frequencies at which hydrogen, the most common element in the universe, readily absorbs and emits energy).
