Researchers at Purdue University have built and demonstrated a prototype for a new class of miniature devices to study synthetic cell membranes in an effort to speed the discovery of new drugs for a variety of diseases, including cancer.
The researchers created a chip about one centimeter square that holds thousands of tiny vessels sitting on top of a material that contains numerous pores. This “nanoporous” material makes it possible to carry out reactions inside the vessels. T

After reaching its observational orbit around Mars a year ago, ESA’s Mars Express has already delivered an avalanche of scientific data of unprecedented quality that have completely changed the way in which we think about the Red Planet.

In order to compare views and discuss the implications of the new discoveries, over two hundred scientists will be attending the first Mars Express science conference, taking place from 21 to 25 February at ESA’s European Space Research and T

Researchers have long puzzled over the apparently multiple causes of complex developmental disorders such as schizophrenia. Individuals seem to be predisposed to the disease by a tragic, mysterious combination of genetics, prenatal trauma, viral infection, and early experience. And its array of symptoms–including hallucinations, delusions, paranoia, and antisocial behavior–has defied simple explanation.

In experiments with rats, however, researchers led by led by Gerard J.M. Ma

UC Davis researchers have discovered two key signals that tell fish how to handle the stress of changing concentrations of salt as they swim through different waters.

Not many fish can travel between saltwater and freshwater. To maintain the right internal salt level, their gills must pump up salt from freshwater but excrete it in the ocean. “Fish that can survive both environments are able to resist many kinds of stress,” said Dietmar Kueltz, an assistant professor of animal

In a new study, researchers present a “cautionary tale” about what may go wrong when using the fledgling science of proteomics to devise a diagnostic test for cancer.

In the February 16 issue of the Journal of the National Cancer Institute, researchers from The University of Texas M. D. Anderson Cancer Center detail why an experimental test intended to identify early ovarian cancer from a small sample of blood is unlikely to lead to a reliable clinical test right away.

“The Web will become more than what we see on our computer screens, it will become a place where computers interact with each other and where meaning is attached to information.” That is the vision behind a cutting-edge Semantic Web project.

For Richard Benjamins, the coordinator of the IST project ESPERONTO, the future of the Semantic Web lies in it becoming “something akin to ambient intelligence” with the meaning of digital information understandable not only by humans but by a
