New research to run cars on flower power

Will the oilfields of the future be full of sunflowers? They could be if Leeds fuel and energy researchers succeed in producing hydrogen from sunflower oil.
Hydrogen is seen as the fuel of the future – able to create electricity with no harmful emissions – to power everything from cars, portable generators to flashlights and even homes and factories.

But where is the hydrogen to come from, and can we mass-produce it without creating more pollution problems? Researchers Valerie Dupont (

Commission to invest Euro 700 million in nanotechnology research

Machines not bigger than a molecule will one day surf our blood stream, search and destroy infected tissues, and heal our wounds. This is just one of the applications of nanotechnology. EU Research Commissioner Philippe Busquin will chair an information day on nanotech new frontiers in Grenoble, France, on 14 June 2002. Nanotech research is still in its start-up phase, and will be far more effective if co-ordinated and supported at EU level. The Commission will therefore allocate € 700 million to nan

Source of physical performance found in brain

New research distinguishes between learning physical skills and brain activity associated with performing those skills

A new study from the Department of Veterans Affairs suggests that the brain’s coordination center is not active while we learn new motor skills – but it is active while we use them. The findings appear in the June 14 issue of Science.
Investigators concentrated on the cerebellum — a part of the brain closely linked to movement (motor skills) and coordinatio

Urine test predicts Alzheimer’s disease

A simple clinical test could make it easier to track and treat Alzheimer’s

A urine sample taken at the doctor’s office can be the step in determining your chances of developing Alzheimer’s disease (AD), according to researchers at the University of Pennsylvania School of Medicine. They have determined that a urine test can reliably detect free radical damage associated with people with Mild Cognitive Impairment (MCI) – a recognized precursor to AD. The test detects isop

Futuristic System Brings Vision to Blind

A Saint Louis University neurosurgeon has become the first U.S. doctor to implant a potentially revolutionary electronic eye device that allows a blind patient to see. He is the only United States doctor ever to perform the procedure.

Kenneth R. Smith Jr., M.D., professor of neurosurgery at Saint Louis University School of Medicine, performed the two- to three-hour surgical procedure in Lisbon, Portugal, in April. He was one of four specialists who operated on eight blind patients who paid

Noah’s Flood Hypothesis May Not Hold Water

Rensselaer Polytechnic Institute Professor Part of International Research Group Refuting Popular Theory

In 1996, marine geologists William Ryan and Walter Pitman published a scientifically popular hypothesis, titled Noah’s Flood Hypothesis. The researchers presented evidence of a bursting flood about 7,500 years ago in what is now the Black Sea. This, some say, supports the biblical story of Noah and the flood.

But, such a forceful flood could not have taken place, says
