Engineers have found a way to pinpoint and identify the tiny iron oxide particles associated with Alzheimer’s and other neurodegenerative diseases in the brain.

The technique is likely to accelerate research on the cause of the diseases and could lead to the first diagnostic procedure for Alzheimer’s in patients while they are alive.

“We’re the first to be able to tell you both the location of the particles and what kind of particles they are,” said Mark Davidson, a Unive

Newly published research by a Princeton engineer suggests that understanding how air travels across the sunroof of a car may one day make jet engines less noisy.

Clarence Rowley, an assistant professor of mechanical and aerospace engineering, did not actually conduct his experiments on a sunroof. Rather, he and collaborators used computer simulations and subsonic wind tunnels at Princeton and at the U.S. Air Force Academy in Colorado Springs, to experiment with models that rese

By combining quantum computation and quantum interrogation, scientists at the University of Illinois at Urbana-Champaign have found an exotic way of determining an answer to an algorithm – without ever running the algorithm.

Using an optical-based quantum computer, a research team led by physicist Paul Kwiat has presented the first demonstration of “counterfactual computation,” inferring information about an answer, even though the computer did not run. The researchers report their

New report suggests promising areas for intervention

With the rapid aging of the population, the National Institutes of Health (NIH) is intensifying the search for strategies to preserve brain health as people grow older. The effort moved an important step forward today with a report by an expert panel to the NIH, suggesting a number of promising avenues for maintaining or enhancing cognitive and emotional function. Specifically, the group said, education, cardiovascular health, p

When spores sent through the mail in 2001 caused 11 people to contract anthrax – ultimately killing five of them – infectious disease specialists noted that the death rate was substantially lower than the historical mortality rate, which approached 100 percent. Many assumed that access to modern intensive care units and more powerful antibiotics made the difference.

But after completing the most comprehensive review of anthrax cases ever conducted, researchers at the Veterans Aff

The tendency to use drugs depends on each individual person. Not all those who have access to drugs become addicts, therefore there may be personality characteristics that influence their use. One such characteristic is the pursuit of new sensations found in people that like looking for risk at all times. Although some studies have already suggested a link between these people and a higher probability of becoming drug addicts, shopaholics or gambling addicts, until now no study has objectively fou
