When Eric Hudson was introduced to high-temperature superconductivity as a graduate student, it was still, so to speak, a hot topic.

The rearing of steelhead trout in hatcheries causes a dramatic and unexpectedly fast drop in their ability to reproduce in the wild, a new Oregon State University study shows, and raises serious questions about the wisdom of historic hatchery practices.

Researchers at Harvard University and the Howard Hughes Medical Institute have found that a simple circadian clock found in some bacteria operates by the rhythmic addition and subtraction of phosphate groups at two key locations on a single protein. This phosphate pattern is influenced by two other proteins, driving phosphorylation to oscillate according to a remarkably accurate 24-hour cycle.

The U.S. Food and Drug Administration announced the nationwide recall of Baker's Premium White Chocolate Baking Squares due to possible contamination.

(AP) -- Shareholders of the nation's only two satellite radio companies are scheduled to vote Nov. 13 on Sirius Satellite Radio Inc.'s proposed multibillion-dollar acquisition of XM Satellite Radio Holdings Inc.

Researchers have uncovered new evidence in mice that may explain how emotionally charged situations can leave such a powerful mark on our memories. Surges of the stress hormone norepinephrine (also known as noradrenaline) that often accompany strong emotions spark a series of molecular events that ultimately strengthen the connections between neurons, the team reports in the October 5, 2007, issue...

American children are drinking too little milk and what they are consuming is too high in fat, according to a Penn State study.

The chemical process known as acetylation plays a central role in cytokine receptor signal transduction - a fundamental biochemical cascade inside cells that controls the activity of antiviral and tumor-suppressing genes.

University of Florida doctors on Wednesday treated their first patient enrolled in a new study designed to test whether injecting stem cells into the heart helps restore blood flow to the organ by prompting new blood vessels to grow.

The Bird Spring Shelf in southeastern California and basins to the west reveal a complex history of late Paleozoic sedimentation, sea-level changes, and deformation along the western North American continental margin. A new book published by the Geological Society of America captures insights into the tectonics and paleogeography of the region.

Moving away from home and adapting to a new social environment are just two of the many challenges that new students face as they enter university. An innovative new study conducted at the University of Alberta has found that these challenges can actually have a negative effect on a student's health.

From an evolutionary perspective, the primary task of an organism is to pass along its genes to future generations. Such genetic transmission is usually assumed to be instinctive. However, a new study shows that species also learn to adapt to their surroundings in order to increase their “reproductive fitness”— the likelihood that they will successfully reproduce.

A Leicester cancer research project, which receives funding from Hope Against Cancer (formerly The Hope Foundation,) is investigating whether an extract from bilberries can prevent or delay the onset of certain cancers.

Scientists of the GSF-National Research Center for Environment and Health found indications for an association between attendance of swimming pools in the first year of life and the frequency of infections. Diarrhea and otitis media during the first year of life are especially noteworthy. No increased risks were found for atopic diseases during the first six years.

The Giant Magellan Telescope (GMT) Consortium announces that the GMT will be constructed at Cerro Las Campanas, Chile. This location was selected for its high altitude, dry climate, dark skies, and unsurpassed seeing quality, as well as its access to the southern skies.

(AP) -- Microsoft Corp. launched a Web site Thursday for managing personal health and medical information, jumping into an industry whose digital future is clouded by privacy worries.

A tiny galaxy, nearly halfway across the universe, the smallest in size and mass known to exist at that distance, has been identified by an international team of scientists led by two from the University of California, Santa Barbara.

Microcrystals take the form of tiny grains resembling powder, which is extremely difficult to study. For the first time, researchers from the European Synchrotron Radiation Facility (ESRF) and the Centre National de Recherche Scientifique used X-ray diffraction at the synchrotron to determine the structure of microcrystal grains of one cubic micrometre. They gained a factor of a thousand on the...

A delegation from Montana will be heading to Russia Sunday to rustle up trade interest in the state's beef cattle livestock and genetics know-how.

Scientists have identified and described stem cells specific to several tissues and organs of the body — key master cells that give rise to the specialized cell types characteristic of that organ. But to date, it hasn`t been possible to pinpoint functioning stem cells in the stomach, either in laboratory animals or people.

An international team has opened a virtual bazaar, called PAZAR, which allows biologists to share information about gene regulation through individually managed 'boutiques' (data collections). According to research published in the online open access journal, Genome Biology, customers can access data without any charge from any boutique or extract information from the 'superstores' that aggregate...

At this year's Little League World Series, new rules for the first time forced players to limit the number of times pitchers could throw the ball, and coaches had to strategize how pitchers were used more carefully.

Diagnosing a risk of fatal lung disorders may be possible by analysing the umbilical cords of premature babies, according to research published in the online open access journal Genome Biology. Until now, paediatricians have not been able to predict the development of bronchopulmonary dysplasia (BPD) because of the difficulties with obtaining lung samples.

Adolescents have grown taller and put on weight over the last thirty years, but the problem of underweight teens may be worse, a study in the online open access journal BMC Public Health suggests. An analysis of the height, weight, and body-mass index of teenagers during 1966-1969 and 1995-1997 in Norway demonstrates a shift towards taller and heavier teenagers, but also hints that there are more...
