Physicists have devised a new experiment that will be used in the quest for exotic forces in nature and “additional spatial dimensions.”

The researchers have demonstrated an innovative way to measure a phenomenon known as the Casimir effect – findings that also could have implications for the design of microscopic machines that contain tiny parts on the size scale of nanometers – or billionths of a meter.

The scientists are taking their theoretical findings a step further by

A new study of the most commonly prescribed post-kidney transplant drug suggests it may not be the most effective weapon to fend off organ rejection and may even damage some donor kidneys. The research, to be presented Nov. 2 at the American Society of Nephrology annual meeting, identified another drug that seems to work better, a finding that could help expand the pool of donor organs.

An analysis by an Ohio University physiologist suggests that large doses of cyclosporine, the most often

Scientists have developed and tested a new imaging technique that reveals the atomic structure of thin films with unprecedented resolution. For the first time, the technique has shown very precisely how the atoms of the first layers of a film rearrange under the action of the substrate on which the film is grown. The results of the study are reported as the cover story of the October issue of Nature Materials.

“This technique directly provides a very precise image of atomic positions within

An enzyme that plays a pivotal role in controlling genes in yeast acts through a more versatile mechanism than was previously thought to be the case, according to a new study by researchers at The Wistar Institute.

Its mode of action is also distinct from that of other members of the vital enzyme family into which it falls, the scientists found. Because the human counterpart of the enzyme has been associated with certain forms of leukemia, this observation raises the possibility that

A wheelchair robot developed by scientists at Coimbra University already has a prototype “capable of navigating without colliding with obstacles by commanded human voice”, as professor Urbano Nunes states, the person with joint responsibility, with professor Gabriel Pires, for the team of professors and students of the Electro-technical Engineering Department responsible for the project.

For the last five years this project has been developed and integrated in degree classes and pos

Scientists at UCLA’s Jonsson Cancer Center have developed the world’s first animal model for mature human B-cell lymphomas, a discovery that may lead to the uncovering of the genetic mutations that cause these types of cancer. Mature B-cell type lymphomas account for about 85 percent of all lymphomas.

The basic science discovery is outlined in the Oct. 29 issue of the peer-reviewed journal Proceedings of the National Academy of Sciences.
