AMES, Iowa – Patricia Thiel of Iowa State University and the Ames Laboratory put a box of tissues to the right, a stack of coasters to the middle and a trinket box to the left. "Nature," she said of her table-top illustration, "doesn't want lots of little things." So Thiel grabbed the smaller things and slid them into a single pile next to the bigger tissue box. "Nature wants one big thing all together, like this." Thiel, an Iowa State Distinguished Professor of Chemistry and a faculty scientist for the U.S. Department of Energy's Ames Laboratory, and James Evans, an ...

Washington, DC – November 2, 2010 – Food safety problems can arise at any of multiple stages of food production, and illnesses that result from them are frequently not detected or reported, according to a new report from the American Academy of Microbiology. The report, "Global Food Safety: Keeping Food Safe from Farm to Table," is based on a colloquium convened by the Academy in 2009. Colloquium participants with expertise in microbiology, public health, food science, and economics reviewed the current state of affairs in microbiological food safety around the world. The ...

As the Arctic warms, a new cache of resources—snow goose eggs—may help sustain the polar bear population for the foreseeable future. In a new study published in an early online edition of Oikos, researchers affiliated with the Museum show that even large numbers of hungry bears repeatedly raiding nests over many years would have a difficult time eliminating all of the geese because of a mismatch in the timing of bear arrival on shore and goose egg incubation. "There have been statements in popular literature indicating that polar bears can extirpate snow geese quickly ...

Which are the best pieces of pork, what their texture is, how moist they are – the secrets pigs keep from even the most skilled butchers – are about to be revealed, thanks to a sophisticated new technique that has been developed by McGill University researchers in conjunction with Agriculture Canada and the pork industry. "This is about giving industry workers better tools to do their job," explained Dr. Michael Ngadi of McGill's Department of Bioresource Engineering. "Computer-aided analysis of meat will result in higher-quality jobs, optimal production, and exports that ...

It's commonly accepted that we appreciate something more if we have to work hard to get it, and a Johns Hopkins University study bears that out, at least when it comes to food. The study seems to suggest that hard work can even enhance our appreciation for fare we might not favor, such as the low-fat, low calorie variety. At least in theory, this means that if we had to navigate an obstacle course to get to a plate of baby carrots, we might come to prefer those crunchy crudités over the sweet, gooey Snickers bars or Peanut M&Ms more easily accessible via the office vending ...

There are disorders and conditions that entail increased itching and can be extremely troublesome for those suffering from it. The mechanisms behind itching are not well understood today. For one thing, what is it about scratching that relieves itching? In the current study, which was performed on mice, the research team led by Professor Klas Kullander at the Department of Neuroscience examined the nerve cells that transfer heat pain. When these nerve cells had lost its capacity to signal, the mice reacted less to heat, as expected, but surprisingly they also started ...

Quebec City, November 4, 2010—A team of Université Laval and Danisco researchers has just unlocked the secret of bacteria's immune system. The details of the discovery, which may eventually make it possible to prevent certain bacteria from developing resistance to antibiotics, are presented in today's issue of the scientific journal Nature. The team led by Professor Sylvain Moineau of Université Laval's Department of Biochemistry, Microbiology, and Bioinformatics showed that this mechanism, called CRISPR/Cas, works by selecting foreign DNA segments and inserting them ...

Can you forge an emotional bond with a brand so strong that, if forced to buy a competitor's product, you suffer separation anxiety? According to a new study from the USC Marshall School of Business, the answer is yes. In fact, that bond can be strong enough that consumers are willing to sacrifice time, money, energy and reputation to maintain their attachment to that brand. "Brand Attachment and Brand Attitude Strength: Conceptual and Empirical Differentiation of Two Critical Brand Equity Drivers," a study published in the November issue of the Journal of Marketing, ...

Menlo Park, Calif.—Calcium regulates many critical processes within the body, including muscle contraction, the heartbeat, and the release of hormones. But too much calcium can be a bad thing. In excess, it can lead to a host of diseases, such as severe muscle weakness, a fatal reaction to anesthesia or sudden cardiac death. Now, using intense X-rays from the Stanford Synchrotron Radiation Lightsource (SSRL) at the Department of Energy's SLAC National Accelerator Laboratory, researchers have determined the detailed structure of a key part of the ryanodine receptor, a ...

Nanoparticles could help smuggle drugs into the gut, according to a study published this month in the International Journal of Nanotechnology. There are several drugs that would have more beneficial therapeutic effects if they could be targeted at absorption by the lower intestine. However, in order to target the colon for treating colon cancer for instance, medication delivered by mouth must surmount several barriers including stomach acidity, binding to mucus layers, rapid clearance from the gut, and premature uptake by cells higher up the gastrointestinal tract. Being ...

PROVIDENCE, R.I. [Brown University] — In a major new study announced today by the National Cancer Institute, researchers including Brown University biostatistian Constantine Gatsonis and his colleagues found that screening for lung cancer using helical CT scanning reduced lung cancer deaths by 20 percent compared to using chest X-rays. "The findings we're announcing today offer the first definitive evidence for the effectiveness of helical CT screening smokers for lung cancer " said Gatsonis, a lead biostatistician in the study and director of the American College of ...

A study funded by the Motor Neurone Disease (MND) Association, in collaboration with the Medical Research Council (MRC), has identified a common signature of nerve damage in the brains of MND patients. The study's exciting findings have been published in the prestigious journal Neurology (2 November 2010). These are the first results to be published from the ongoing Oxford Study for Biomarkers in MND/ALS (BioMOx). MND research is being held back by the lack of an early diagnostic test and predictable markers of the progression of the disease – biomarkers. Patients ...

Most people are familiar with the concept that sentences have syntax. A verb, a subject, and an object come together in predictable patterns. But actions have syntax, too; when we watch someone else do something, we assemble their actions to mean something, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. "There are oceans and oceans of work on how we understand languages and how we interpret the things other people say," says Matthew Botvinick of Princeton University, who cowrote the paper with his ...

November 4, 2010 – (BRONX, NY) -- A team of scientists has found a way to eliminate a debilitating side effect associated with one of the main chemotherapy drugs used for treating colon cancer. The strategy used in their preclinical research—inhibiting an enzyme in bacteria of the digestive tract—could allow patients to receive higher and more effective doses of the drug, known as CPT-11 or Irinotecan. The study, spearheaded by scientists at the University of North Carolina at Chapel Hill and involving collaborators at Albert Einstein College of Medicine of Yeshiva University ...

Scientists have long known that large volcanic explosions can affect the weather by spewing particles that block solar energy and cool the air. Some suspect that extended "volcanic winters" from gigantic eruptions helped kill off dinosaurs and Neanderthals. In the summer following Indonesia's 1815 Tambora eruption, frost wrecked crops as far away as New England, and the 1991 blowout of the Philippines' Mount Pinatubo lowered average global temperatures by 0.7 degrees F--enough to mask the effects of greenhouse gases for a year or so. Now, in research funded by the ...

Many children, especially those with eczema, are unnecessarily avoiding foods based on incomplete information about potential food-allergies, according to researchers at National Jewish Health. The food avoidance poses a nutritional risk for these children, and is often based primarily on data from blood tests known as serum immunoassays. Many factors, including patient and family history, physical examination, and blood and skin tests, should be used when evaluating potential food allergies. The oral food challenge, in which patients consume the suspected allergenic food, ...

COLUMBIA, Mo. – Estimating the long-term impact of agriculture on land is tricky when you don't have much information about what a field was like before it was farmed. Some fields in Missouri started producing crops more than a century ago—long before anyone kept detailed records about the physical and chemical properties of the soil in a field. Researchers can't go back in time to revisit old fields in their pristine state, but a University of Missouri graduate student did perhaps the next best thing, using a detailed computer model to simulate, year-by-year, the effects ...
