The star-nosed mole gives a whole new meaning to the term “fast food.”

A study published this week in the journal Nature reveals that this mysterious mole has moves that can put the best magician to shame: The energetic burrower can detect small prey animals and gulp them down with a speed that is literally too fast for the human eye to follow.

It takes a car driver about 650 milliseconds to hit the brake after seeing the traffic light ahead turn red. The star-nosed mol

A new MORI survey published today is the first to take a wide-ranging look at the issues of reliability of information found on the Internet, and the extent to which users feel they can trust the information they find there.

The reputation of an organisation and the trustworthiness of the content of websites are important factors in people’s attitudes, the survey found. Information provided via the websites of more established organisations such as museums, libraries and archive

Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) at the Free University of Brussels have recently published results that show promise in the quest for a new remedy for chronic urinary tract infections. The researchers have shown that administration of the sugar Heptyl-á-D-mannoside can prevent E. coli bacteria from binding to the wall of the urinary tract − which is the first step in the development of the infection.

A widespread problem

Researchers at The University of Texas M. D. Anderson Cancer Center have discovered a cluster of 12 genes on the X chromosome in mice that appears to play an important role in reproduction. Reporting in the journal Cell, the scientists showed that knocking out just one of the genes resulted in reduced fertility in male mice.

The researchers found the cluster, which they dubbed the reproductive homeobox X-linked (or Rhox) genes, is selectively expressed in male and female reprod

Take a moment and look at a picture near you. What did you see? How long did it take you to understand what was in the image, meaning how long did it take you to realize the green blob was a tree? Or that the orange circle was a piece of fruit? Most likely you assume that it took you no time at all, you just knew.

Psychologists who study how we perceive images used to think that, before the process of object recognition and categorization could begin, the brain must first separate

An analysis of previously uncharted chemical contents, mostly carbohydrates, in U.S.-consumed mushrooms shows that these fruity edible bodies of fungi could be tailored into dietary plans to help fill various nutritional needs.

Using modern analytic tools, scientists at the University of Illinois at Urbana-Champaign found that the six mushroom varieties tested – in raw and cooked forms and at various harvest times and maturity levels – are rich in total dietary fibers, including

A Howard Hughes Medical Institute (HHMI) professor and 138 of his undergraduates have co-authored a paper that provides the first genome-wide estimate of vital genes that are also essential for eye development of the common fruit fly, Drosophila melanogaster. The undergraduates are students in a unique biology class taught by HHMI professor Utpal Banerjee at the University of California, Los Angeles.

Banerjee and his students identified 501 essential genes responsible for proces

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.

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

A particle accelerator operates in Earth’s upper atmosphere above major thunderstorms at energies comparable to some of the most exotic environments in the universe, according to new satellite observations of terrestrial gamma-ray flashes.

Terrestrial gamma-ray flashes (TGFs) are very short blasts of gamma rays, lasting about one millisecond, that are emitted into space from Earth’s upper atmosphere. The gamma rays are thought to be emitted by electrons traveling at n

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

Distributed computing project to search for gravitational waves.

A new grassroots computing project dubbed Einstein@Home, which will let anyone with a personal computer contribute to cutting edge astrophysics research, will be officially announced at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington DC on Saturday, February 19. LIGO Laboratory Director Barry Barish of Caltech and Einstein@Home Principal Investigator Bruce Allen

Earth is showered constantly by particles called muons that are created by cosmic rays, and clever scientists are finding ways to use them as probes of dense objects, including a massive pyramid in Mexico and volcanoes in Japan. American researchers also have proposed using the energetic particles to detect smuggled nuclear materials in vehicles and cargo containers.

Muons are formed when cosmic rays from deep space interact with the atmosphere. The particles, which strike earth&#1

Observing the edge of the famous Horsehead Nebula with the IRAM interferometer located on the Plateau de Bures (France), a team of French and Spanish astronomers discovered a large quantity of small hydrocarbon molecules. This is a surprise because the intense UV radiation illuminating the Nebula should destroy the small hydrocarbons near the edge. The astronomers suggest that these molecules might result from the fragmentation of giant molecules, called “polycyclic aromatic hydrocarbons” (PAH

It will be possible to forecast any natural or social cataclysm by attentively observing the speed of the Earth’s rotation and shift of its poles.

The Earth rotates non-uniformly, its poles move, and the rotation axis fluctuates in space. According to the opinion of N.S. Sidorenkov, Doctor of Science (Physics&Mathematics), knowledge of reasons and regularities of our planet’s movement gives the opportunity to forecast with high precision the weather, earthquakes, convulsion of

A groundbreaking new treatment to combat the hospital killer bug MRSA, which is estimated to cause up to 5,000 deaths a year in Britain, is being developed by a University of Sussex scientist.

Philip Parsons, a professor of organic chemistry, has devised a simple “one-pot” method to make a synthetic version of a natural antibiotic, lactonamycin, which could be used to treat infected patients. He has now received a £280,000 grant from the Engineering and Physical Sciences Research

New hope for sufferers of glaucoma and spinal cord injuries

For the first time, scientists have regenerated a damaged optic nerve — from the eye to the brain. This achievement, which occurred in laboratory mice and is described in the March 1, 2005 issue of the Journal of Cell Science, holds great promise for victims of diseases that destroy the optic nerve, and for sufferers of central nervous system injuries. “For us, this is a dream becoming reality,” says Dr. Dong Feng Chen,

VLT NACO Performs Outstanding Observations of Titan’s Atmosphere and Surface

On January 14, 2005, the ESA Huygens probe arrived at Saturn’s largest satellite, Titan. After a faultless descent through the dense atmosphere, it touched down on the icy surface of this strange world from where it continued to transmit precious data back to the Earth.

Several of the world’s large ground-based telescopes were also active during this exciting event, observing Titan before and nea

Data from the Cassini-Huygens satellite showing oxygen ions in the atmosphere around Saturn’s rings suggests once again that molecular oxygen alone isn’t a reliable indicator of whether a planet can support life.

That and other data are outlined in two papers in the Feb. 25 issue of the journal Science co-authored by University of Michigan engineering professors Tamas Gombosi, J. Hunter Waite and Kenneth Hansen; and T.E. Cravens from the University of Kansas. The papers b
