New Material May Lead To Advances In Quantum Computing
Though we may not care to admit it, what other people think about something can affect what we think about it. This is how critics become influential and why our parents` opinions about our life choices continue to matter, long after we`ve moved out. But what kind of opinions have the most effect" An important new study in the Journal of Consumer Research reveals that negative opinions cause the...
New plastic is strong as steel, transparent
Scientists at Florida State University`s National High Magnetic Field Laboratory and the university`s Department of Chemistry and Biochemistry have introduced a new material that could be to computers of the future what silicon is to the computers of today.
New research sheds light on shimmering superconductivity and the courtship of electrons
By mimicking a brick-and-mortar molecular structure found in seashells, University of Michigan researchers created a composite plastic that's as strong as steel but lighter and transparent.
Payload is loaded into shuttle Discovery
In their normal state, electrons repel each other because of their charge, but in the state of superconductivity, electrons pair up. John Schlueter, a chemist from the U.S. Department of Energy's Argonne National Laboratory, collaborated with a team of researchers from the University of Oxford to better understand how this unlikely courtship occurs.
Physics professor probes superconductivity
The U.S. space agency said the payload for the next mission to the International Space Station has been installed in space shuttle Discovery's cargo bay.
Salmonid hatcheries cause 'stunning' loss of reproduction
When Eric Hudson was introduced to high-temperature superconductivity as a graduate student, it was still, so to speak, a hot topic.
Simplest circadian clocks operate via orderly phosphate transfers
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.
White chocolate baking squares recalled
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.
XM, Sirius Shareholders to Vote on Deal
The U.S. Food and Drug Administration announced the nationwide recall of Baker's Premium White Chocolate Baking Squares due to possible contamination.
How emotionally charged events leave their mark on memory
(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.
Kids still not drinking enough milk
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...
Researchers make major signal transduction discovery
American children are drinking too little milk and what they are consuming is too high in fat, according to a Penn State study.
Researchers test stem cell therapy for heart patients
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.
Microfossils disclose geologic history of eastern California
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.
Starting university may be hazardous to your health: study
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.
In birds, expecting to mate leads to higher fertilization rates
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.
Bilberry extract -- can it help prevent certain cancers?
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.
Evidence of a relationship between swimming babies and infections
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.
Giant Magellan telescope site selected
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.
Microsoft Launches Health Records Site
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.
Scientists 'weigh' tiny galaxy halfway across universe
(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.
Unveiling the structure of microcrystals
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.
Montana beef experts heading to Russia
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...
Stomach stem cell discovery could bring cancer insights
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.
