Astronomers have observed that galaxies rotate with such great speed they should be torn apart, yet they are not. It is as if some hidden mass is holding the…
Producing traditional solar cells made of silicon is very energy intensive. On top of that, they are rigid and brittle. Organic semiconductor materials, on the…
When an individual cell is placed on a level surface, it does not keep still, but starts moving. This phenomenon was observed by the British cell biologist…
An Australian geologist has identified what could be the first ever active flow of fluids through gullies on Mars.
University of Melbourne geologist, Dr Nick Hoffman, identified recent gully and channel development near the polar regions of Mars from images taken by the Mars Global Surveyor spacecraft. But contrary to the majority of scientific opinion which suggests that such features were carved by liquid water, Hoffman says the flow is most likely frozen carbon dioxide.
Lawrence Livermore National Laboratory astronomers are major partners in a scientific collaboration that will conduct an extremely novel search for small, comet-like bodies in the outer solar system using four half-meter telescopes. The work was described today at the winter meeting of the American Astronomical Society.
Rather than look for the light reflected directly by these objects (as is customary astronomy practice), this project will search for those very rare moments when one of these ob
University of Colorado at Boulder researchers have conducted the most sensitive search to date for gravitational-strength forces between masses separated by only twice the diameter of a human hair, but they have observed no new forces.
The results rule out a substantial portion of parameter space for new forces with a range between one-tenth and one-hundredth of a millimeter, where theoretical physicists using string theory have proposed that “moduli forces” might be detected, according to
Since November, a physics experiment called the Cryogenic Dark Matter Search (CDMS II) has been looking for components of dark matter, the primary “stuff” of which the universe is made. Conducted from the Soudan Underground Mine in northern Minnesota, the search is for postulated dark matter particles called WIMPS–weakly interacting massive particles. So far, the experiment has found no WIMPs, but neither has it found contamination from stray neutrons. CDMS II member Priscilla Cushman, a physics pro
Could boost surveillance in public places
A new three-dimensional multi-camera system that allows viewers to search areas from various vantage points could one day boost surveillance in public places such as airports and train stations, say University of Toronto researchers. The system – based on ideas published in the October proceedings of the 2004 IEEE International Conference on Systems, Man and Cybernetics – allows users to capture images of a scene from multiple angles and
Louisiana Tech has reached further in its help to Katrina victims, this time through technology.
Dr. Box Leangsuksun, an associate professor of computer science, along with five computer science graduate students, has created a new Web site aimed at locating people displaced by Hurricane Katrina.
His hope is that the site will help streamline the search process. Other sites are available that perform similar tasks, he said, but they contain so much information that users c
A Danish-led research project has made encouraging progress toward using advanced mathematics as the basis of an improved method for indexing and searching medical images in the huge digital databases of clinics and hospitals.
Completed in November 2005, the DSSCV consortiums long-term goal was to contribute to software tools allowing doctors and hospital technicians to quickly search and match X-rays, magnetic resonance images and computed 3D tomography scans, particularly of the cra
Million dollar study is an international collaboration supported by government, top ALS organizations
Though its the more common form of the disease, sporadic ALS, which affects roughly 90 percent of those living with the fatal neurodegenerative illness, has been the one less studied, simply because, unlike familial ALS, no genes have turned up.
This week, however Bryan Traynor, M.D. and John Hardy, Ph.D., scientist-grantees with the Packard Center for ALS Resear
