New research shows X-ray bursts from the Sun cause dramatic alterations to the planet’s ionosphere

Boston University astronomers announced today the first clear evidence that solar flares change the upper atmosphere of Mars. In an article published in the February 24th issue of the journal Science, the researchers describe how X-ray bursts from the Sun in April 2001 recorded by satellites near Earth reached Mars and caused dramatic enhancements to the planet’s ionosp

New Hubble Images Offer Best View yet of Distant Planet and its Three Satellites

In the Feb. 23 issue of the journal Nature, a team led by Dr. Hal Weaver of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., describes its discovery of two new moons around Pluto – a finding that made the ninth planet the first Kuiper Belt object known to have multiple satellites.

In a companion paper, also in the Feb. 23 Nature, discovery team members led by Dr. A

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
