The September cover story of the nation's leading cancer journal, "Cancer Research," features a new study from The Hormel Institute, University of Minnesota, that links capsaicin, a component of chili peppers, to skin cancer. While the molecular mechanisms of the cancer-promoting effects of capsaicin are not clear and remain controversial, The Hormel Institute has shown a definite connection to formation of skin cancer through various laboratory studies. Ann Bode, professor in the institute's Cellular and Molecular Biology Research Section, led the research team on this ...

BETHESDA, MD, SEPT 2, 2010⎯The old joke is a joke no more. In a special September issue of the ASCB's online journal, CBE—Life Sciences Education (CBE-LSE), the adage that biology is for science students who don't do math is laid to rest forever. "Bio-math" or "math-bio" is in the future for students of both disciplines, say the contributors of seven essays and 17 research articles on new ways to integrate mathematical thinking into biology education and introduce biological problems into math learning. "The national scientific and academic community has issued ...

MANHATTAN, KAN. -- People who believe that fate and chance control their lives are more likely to be superstitious -- but when faced with death they are likely to abandon superstition altogether, according to a recent Kansas State University undergraduate research project. The project, led by Scott Fluke, a May 2010 K-State bachelor's graduate in psychology, Olathe, focuses on personality traits that lead to superstition. Fluke received a $500 Doreen Shanteau Undergraduate Research Fellowship in 2009 to work with the team of Russell Webster, graduate student in psychology, ...

Sugar, salt, alcohol and a little serendipity led a Northwestern University research team to discover a new class of nanostructures that could be used for gas storage and food and medical technologies. And the compounds are edible. The porous crystals are the first known all-natural metal-organic frameworks (MOFs) that are simple to make. Most other MOFs are made from petroleum-based ingredients, but the Northwestern MOFs you can pop into your mouth and eat, and the researchers have. "They taste kind of bitter, like a Saltine cracker, starchy and bland," said Ronald ...

The academic performance of adolescents will suffer in at least one of four key subjects –– English, math, science, history –– if their DNA contains one or more of three specific dopamine gene variations, according to a study led by renowned biosocial criminologist Kevin M. Beaver of The Florida State University. The research sheds new light on the genetic components of academic performance during middle and high school, and on the interplay of specific genes and environmental factors such as peer behavior or school conditions. "We believe that dopaminergic genes ...

Studies have shown that heat-stressed dairy cows suffer from damage to their ovarian follicles. Moreover, the eggs produced by the damaged follicles may also be damaged, said Dr. Todd Bilby, Texas AgriLife Extension Service dairy specialist. Worse, after becoming heat-stressed, other studies have shown the eggs she ovulates for the next 40 or 50 days are likely to be damaged as well, according to Bilby. Bilby and his graduate student, Brandi Stewart, have found a way to double pregnancy rates during the summer and increase the number of heifers born as compared with ...

PASADENA, Calif.—Researchers at the California Institute of Technology (Caltech) have devised a new technique—using a sheet of carbon just one atom thick—to visualize the structure of molecules. The technique, which was used to obtain the first direct images of how water coats surfaces at room temperature, can also be used to image a potentially unlimited number of other molecules, including antibodies and other biomolecules. A paper describing the method and the studies of water layers appears in the September 3 issue of the journal Science. "Almost all surfaces have ...

New Orleans, LA – In a first person paper published in the August 27, 2010 issue of Childhood Obesity, Dr. Melinda Sothern, Director of Health Promotion and Professor of Public Health at LSU Health Sciences Center New Orleans, provides three ways to de-program the 1950s obesity trinity underlying the current obesity epidemic in the United States and protect future generations from its health consequences. "The combination of prenatal tobacco use, infant formula, and frequent pregnancies— i.e., the obesity trinity—synergistically created the first generation of nutritionally ...

The treatment has been proven to work for the sickest patients using ...

Hurricane Earl is still a powerful category four hurricane on the Saffir-Simpson Scale as it approaches the North Carolina coast today. NASA's Tropical Rainfall Measuring Mission (TRMM) satellite observed the high rates rain was falling within Earl, in some areas more than 2 inches per hour. Today, the Global Hawk unmanned aircraft is also flying into the eye of Hurricane Earl at altitudes of 60,000 feet to gather information about the storm. Hurricane Earl became the most powerful hurricane of the 2010 Atlantic season early on September 2 when its sustained winds reached ...

ANN ARBOR, Mich.---Protecting helicopters in combat from heat-seeking missiles is the goal of new laser technology created at the University of Michigan and Omni Sciences, Inc., which is a U-M spin-off company. "Battlefield terrain in places like Afghanistan and Iraq can be so rough that our troops have often had to rely on helicopters, and they can be easy targets for enemies with shoulder-launched missiles," said Mohammed Islam, a professor in the Department of Electrical Engineering and Computer Science. "Our lasers give off a signal that's like throwing sand in ...

Bermuda has warnings up as Tropical Storm Fiona approaches, and GOES-13 satellite imagery from today shows that Fiona, although packing a punch, is a much smaller system that her brother, the Category 4 Hurricane Earl. A tropical storm warning is in effect for Bermuda today, Sept. 2, as tropical storm force winds are expected there by late Friday. Bermuda can expect between 1 to 3 inches of rainfall from Fiona. When the Geostationary Operational Environmental Satellite called GOES-13 captured a visible image of Tropical Storm Fiona approaching Bermuda this afternoon ...

BIRMINGHAM, Ala. – Cigarette smoke shuts off a key enzyme in airways that regulates the body's response to inflammation, according to findings from the University of Alabama at Birmingham published online today at Science Express. The UAB researchers say smoke inhibits the enzyme, called Leukotriene A4 Hydrolase (LTA4H), causing it to fail in its job of shutting down white blood cells following a successful response to inflammation. The team says the research study identified a previously unknown substrate of LTA4H called proline-glycine-proline (PGP). In a normal ...

COLUMBUS, Ohio – There is yet no straightforward way to determine the optimal dose level and treatment schedules for high-dose radiation therapies such as stereotactic radiation therapy, used to treat brain and lung cancer, or for high-dose brachytherapy for prostate and other cancers. Radiation oncologists at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC-James) may have solved the problem by developing a new mathematical model that encompasses all dose levels. Typically, radiation ...

BETHESDA, Md., Sept. 2, 2010 – The American Society for Biochemistry and Molecular Biology expressed its disapproval and disappointment this week in response to the Aug. 23 ruling in the U.S. District Court for the District of Columbia that granted a preliminary injunction barring federal funding of embryonic stem-cell research. In a statement, the society said the decision, which came in response to a lawsuit filed by two adult stem-cell researchers, effectively halts human embryonic stem-cell research in the United States and "represents a crossroads in American scientific ...

COLLEGE PARK, Md. – A new report by terrorism researchers at the University of Maryland concludes that the deadly hostage-taking incident at the Discovery Communications headquarters in suburban Washington, D.C. meets the criteria of a terrorist act – a rare one for media organizations and the nation's capital region. Hostage-taking, though, is a familiar pattern in capital-region terror, the researchers add. The report from the University of Maryland's START Center – the federally funded National Consortium for the Study of Terrorism and Responses to Terrorism – also ...

Tropical Depression Nine strengthened yesterday into Tropical Storm Gaston, but today it ran into dry and stable air and weakened back into a depression again. When NASA's Aqua satellite flew over Gaston early this morning, Sept. 2 at 0423 UTC (12:23 a.m. EDT), the infrared image taken from the Atmospheric Infrared Sounder (AIRS) instrument showed that Tropical Depression Gaston seemed to have a compact circulation with some high, cold thunderstorm cloud tops around its center of circulation. Those clouds reached so high into the troposphere that they were colder than ...

AMES, Iowa – Iowa State University researchers have found a way to produce high-value chemicals such as ethylene glycol and propylene glycol from biomass rather than petroleum sources. Walter Trahanovsky, an Iowa State professor of chemistry who likes to write out the chemical structures of compounds when he talks about his science, was looking to produce sugar derivatives from cellulose and other forms of biomass using high-temperature chemistry. And so he and members of his research group studied the reactions of cellulosic materials in alcohols at high temperatures ...

ANN ARBOR, Mich. — School children who consume foods purchased in vending machines are more likely to develop poor diet quality – and that may be associated with being overweight, obese or at risk for chronic health problems such as diabetes and coronary artery disease, according to research from the University of Michigan Medical School. The study also looked at foods sold in school stores, snack bars and other related sales that compete with USDA lunch program offerings and found that these pose the same health and diet risks in school-aged children. "The foods that ...
