Toshiba boffins prep laptop fuel cell

March 6, 2003

Toshiba has figured out how to power a portable computer using fuel cell technology without the need for a power unit larger than the PC itself.

An international team of researchers has designed Graphone, a new magnetic nanomaterial made by adding hydrogen atoms to graphene (a form of carbon), with the potential for novel applications in spintronics devices for memory and data processing.

Blue LEDs to reset tired truckers’ body clocks

March 19, 2008

Blue LEDs in truck cabs and truck stops could be the key to reducing accidents caused by drowsy drivers by convincing the brain it’s morning, say Rensselaer Polytechnic Institute researchers.

Nearly 30% of all fatal accidents involving large trucks in the US happen during the hours of darkness.

The lie detector you’ll never know is there

January 5, 2006

THE US Department of Defense has revealed plans to develop a lie detector that can be used without the subject knowing they are being assessed.

The Remote Personnel Assessment (RPA) device will also be used to pinpoint fighters hiding in a combat zone, or even to spot signs of stress that might mark someone out as a terrorist or suicide bomber.

Arabic In, English Out

March 24, 2003

A new device being tested at the Office of Naval Research promises simultaneous machine translation and interpretation, using a blend of voice recognition, speech synthesis and translation technologies.

Snort stem cells to get them to brain

September 11, 2009

Snorting stem cells might be a way of getting large numbers of stem cells or therapeutic proteins such as neural growth factor into the brain without surgery, University Hospital of Tübingen researchers have found in an experiment with mice.

Signs of Hidden Ocean Underneath Titan’s Crust

March 24, 2008

Johns Hopkins University Applied Physics Laboratory scientists say the observed slippage in Titan’s rotation suggests water between its surface and core, and a higher likelihood of ancient life on Saturn’s biggest moon.

Taiwan breeds green-glowing pigs

January 13, 2006

Scientists in Taiwan say they have bred three pigs that glow in the dark.

The pigs are transgenic, created by adding genetic material from jellyfish into a normal pig embryo. The scientists will use the transgenic pigs to study human disease.

Because the pig’s genetic material is green, it is easy to spot. So if, for instance, some of its stem cells are injected into another animal, scientists… read more

Speed of brain signals clocked

July 6, 2011

Two studies featuring research from Weill Cornell Medical College have uncovered details have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons — a dance of chemical messages so delicate that missteps often lead to neurological dysfunctions, such as Alzheimer’s disease, Parkinson’s disease, schizophrenia and other neurodegenerative and psychiatric disorders.

Speed of vesicle recovery
The first study… read more

Measuring the Risks of Nanotechnology

April 8, 2003

Do breakthroughs in nanotechnology present unique health and environmental dangers that need to be studied?

How Quantum Probability Theory Could Explain Human Logical Fallacies

September 17, 2009

Te principles of quantum information processing, including the ideas of superposition and interference, lead to better models of the way humans make decisions, suggests Jerome Busemeyer at Indiana University and colleagues.

Six more genes tied to diabetes

March 31, 2008

Oxford, Harvard, and National Human Genome Research Institute researchers and their colleagues have identified six new unexpected genetic variants involved in type 2 diabetes, boosting to 16 the total number of genetic factors associated with increased risk of the disease.

The new variant most strongly associated with type 2 diabetes was also recently implicated in prostate cancer.

Type 2 diabetes affects more than 200 million people worldwide, including… read more

Intel shows test chips made on future processes

January 26, 2006

Intel has created test chips made on the 45-nanometer process and will likely begin shipping processors, flash, and other chips based on that process in the second half of 2007, according to Mark Bohr, director of process architecture and integration at Intel.

Although these are just test chips, the milestone is an important indication that Intel’s overall manufacturing strategy remains on track and in sync with Moore’s law. However,… read more

Researchers demystify a fountain of youth in the adult brain

July 14, 2011

A “fountain of youth” that sustains the production of new neurons in the brains of rodents may also be present in the human brain, researchers at Duke University Medical Center have found.

The existence of a vital support system of cells around stem cells in the brain explains why stem cells by themselves can’t generate neurons in a lab dish, a major roadblock in using… read more

Dealing with future nanotech dangers

April 22, 2003

New York — The Center for Responsible Nanotechnology (CRN) issued a report today identifying 11 significant risks of molecular nanotechnology (MNT) along with possible solutions.

MNT has “the potential to disrupt many aspects of society and politics,” the report says. “The power of the technology may cause two competing nations to enter a disruptive and unstable arms race. The flexibility and small size of molecular manufacturing systems and their… read more
