Researchers Enable Unprecedented Sampling Using Desktop Computers with Off-the-Shelf Upgrade Using just an upgraded desktop computer equipped with a relatively inexpensive graphics processing card, a team of computer scientists and biochemists at the University of California, San Diego, has developed advanced GPU accelerated software and demonstrated for the first time that this approach can sample biological events that occur on the millisecond timescale.

An international research team, led from the University of Leeds, has found that a common anti-angina drug could help protect the heart against carbon monoxide poisoning. Animal studies have shown that the anti-angina drug ranolazine can significantly reduce the number of deaths from arrhythmias – irregular or abnormally paced heartbeats – that have been triggered by carbon monoxide.

MIT team discovers way of making perfectly ordered and repeatable surfaces with patterns of microscale wrinkles. The wrinkles on a raisin result from a simple effect: As the pulp inside dries, the skin grows stiff and buckles to accommodate its shrinking size. Now, a team of researchers at MIT has discovered a way to harness that same principle in a controlled and orderly way, creating wrinkled surfaces with precise sizes and patterns.

UCLA researchers have come across an unexpected potential use for fluoxetine - commonly known as Prozac - which shows promise as an antiviral agent. The discovery could provide another tool in treating human enteroviruses that sicken and kill people in the U.S. and around the world. Human enteroviruses are members of a genus containing more than 100 distinct RNA viruses responsible for various life threatening infections, such as poliomyelitis and encephalitis.

One of the most daunting challenges facing pharmaceutical scientists today are "undruggable proteins" - the approximately 80% of proteins involved in human disease that do not interact with current drugs. Yale researchers have identified a novel way to design drugs for these previously inaccessible proteins.

Scientists at the University of Birmingham have developed a method to visualise gold on the nanoscale by using a special probe beam to image 20 atoms of gold bound together to make a cluster. The research is published today (26 July 2012) in the Royal Society of Chemistry's journal Nanoscale. Physicists have theorised for many years how atoms of gold and other elements would be arranged and ten years ago the structure of a 20-atom tetrahedral pyramid was proposed by scientists in the US.

n international team of scientists, led by researchers from the Department of Pediatrics at the University of California, San Diego School of Medicine, have identified the first reported inhibitors of a key enzyme involved in survival of the parasite responsible for malaria. Their findings, which may provide the basis for anti-malarial drug development, are currently published in the online version of the Journal of Medicinal Chemistry .

AUSTIN, Texas — It's theoretically possible to produce about 500 times as much energy from algae fuels as is needed to grow the fuels, according to a new study by researchers at The University of Texas at Austin. However, limited by existing technology, the researchers found in a separate study that their algae growing facility is getting out about one-five hundredth as much energy as it currently puts in to grow the fuels.

ANN ARBOR, Mich.-Why do we age, and what makes some of us live longer than others? For decades, researchers have been trying to answer these questions by elucidating the molecular causes of aging. One of the most popular theories is that the accumulation of oxygen radicals over time might be the underlying culprit in aging.

Neanderthals were more sophisticated than we'd thought previously, with the first evidence that they cooked plants for food and used plants for medicine found by an international team of scientists, including Professor Les Copeland from the University of Sydney's Faculty of Agriculture and Environment.

Researchers find new method for making spherical particles, from nanoscale to pinhead-sized - including complex beach-ball-like shapes. Researchers at MIT and the University of Central Florida (UCF) have developed a versatile new fabrication technique for making large quantities of uniform spheres from a wide variety of materials - a technique that enables unprecedented control over the design of individual, microscopic particles.

From driftwood traveling down a river to a blood cell flowing through your artery, objects moving in a stream of fluid are mostly thought to passively go with the flow but not disturb it in controllable ways. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have recently found that objects within a confined stream create controllable disturbances that can be used to move mass or heat at high rates, potentially providing simple solutions to performing chemical reactions on particles or cooling microelectronic chips.

Biologists at UC San Diego have discovered a chemical that offers a completely new and promising direction for the development of drugs to treat metabolic disorders such as type 2 diabetes-a major public health concern in the United States due to the current obesity epidemic.

Research at Oxford University that led to a new type of sensor enabling people with diabetes to easily and accurately monitor their own blood sugar (glucose) levels has been celebrated with the unveiling of a special plaque. The National Chemical Landmark plaque from the Royal Society of Chemistry [ RSC ] recognises work by Allen Hill, Tony Cass , and Graham Davis at Oxford's Department of Chemistry.

A newly published article in Physical Review Letters eliminates one of the top unsolved theoretical problems in chemical physics as ranked by the National Research Council in 1995. Scientists now can more accurately predict the dynamic behavior of electrons in atoms and molecules in chemical reactions that govern a wide range of phenomena, including the fuel efficiency of combustion engines and the depletion of the atmospheric ozone.

Researchers at Imperial College London have discovered a molecule that plays an important role in driving prostate cancer growth, and could be a target for new therapies. About 36,000 men are diagnosed with prostate cancer each year in the UK, making it the most common cancer in men.

Titan's tides point to hidden ocean Nothing like it has been seen before beyond our own planet: large tides have been found on Saturn's moon Titan that point to a liquid ocean - most likely water - swirling around below the surface. On Earth, we are familiar with the combined gravitational effects of the Moon and Sun creating the twice-daily tidal rise and fall of our oceans.

Breakthrough could reduce costs for the consumer MINNEAPOLIS / ST. PAUL (06/28/2012) —University of Minnesota engineering researchers are leading an international team that has made a major breakthrough in developing a catalyst used during chemical reactions in the production of gasoline, plastics, biofuels, pharmaceuticals, and other chemicals.

Exhumed rocks reveal Mars water ran deep By studying rocks blasted out of impact craters, ESA's Mars Express has found evidence that underground water persisted at depth for prolonged periods during the first billion years of the Red Planet's existence. Impact craters are natural windows into the history of planetary surfaces - the deeper the crater, the further back in time you can probe.

Compared to normal cells, cancer cells have a prodigious appetite for glucose, the result of a shift in cell metabolism known as aerobic glycolysis or the "Warburg effect." Researchers focusing on this effect as a possible target for cancer therapies have examined how biochemical signals present in cancer cells regulate the altered metabolic state.
