Researchers at the Institute for Genomic Biology at the University of Illinois have developed a way to harness the prodigious quantities of both genomic and metabolic data being generated with high-throughput genomics and other techniques. They have developed an algorithm that automatically integrates both data sets. The model, called probabilistic regulation of metabolism (PROM), enables researchers to perturb a given regulatory gene or metabolic process and see how that affects the entire network. "PROM provides a platform for studying the behavior of networks in a ...

Does thinking about time or money make you happier? A new study published in Psychological Science, a journal of the Association for Psychological Science, finds that people who are made to think about time plan to spend more of their time with the people in their lives while people who think about money fill their schedules with work, work, and—you guessed it—more work. To find out how thinking about time or money makes people feel, Cassie Mogilner of the University of Pennsylvania designed an experiment, carried out online with adults from all over the United States, ...

PROVIDENCE, R.I. [Brown University] — As the United States seeks to lessen its reliance on foreign oil, biodiesel is expected to play a role. According to the National Renewable Energy Laboratory, a branch of the Department of Energy, biodiesel "represents a significant energy resource and could someday supply 3 percent to 5 percent of the distillate fuel market." One major obstacle to achieving that goal is figuring how to efficiently convert the abundant stocks of waste vegetable oil (oil used after cooking French fries, for example) into biodiesel fuel. Current techniques ...

The way melanoma cells use the immune system to spread and develop into lung tumors may lead to a therapy to decrease development of these tumors, according to Penn State researchers. "Melanoma is the most aggressive and metastatic form of skin cancer," said Gavin Robertson, professor of pharmacology, pathology, dermatology and surgery in the Penn State College of Medicine. "Therefore, identifying proteins and molecular mechanisms that regulate metastasis is important for developing drugs to treat this disease." Metastasis is a complex process in which cancer cells ...

CAMBRIDGE, Mass. -- By creating a better way to see molecules at work in living brain cells, researchers affiliated with MIT's Picower Institute for Learning and Memory and the MIT Department of Chemistry are helping elucidate molecular mechanisms of synapse formation. These studies could also help further understanding of how synapses go awry in developmental diseases such as autism and Fragile X syndrome. The study will appear in the Oct. 7 issue of Cell. Using the new technique, which is more accurate and sensitive than existing methods, the researchers found that ...

WASHINGTON—October 7, 2010—The U.S. invested $139 billion last year in health research from all public and private sources, according to Research!America's latest annual estimate. That amount represents only 5.6% of the $2.47 trillion overall U.S. health spending in 2009—or 5.6¢ of every health dollar—which varies no more than 0.2% from 2005 levels. The estimate is available here: http://www.researchamerica.org/uploads/healthdollar09.pdf. The 2009 investment grew by only 0.1% over 2008. This small increase can be attributed largely to the federal stimulus funding ...

NASA satellites have collected data as the Atlantic Ocean's Tropical Depression 17 has undergone two changes in less than 24 hours. Since Oct. 6, the depression has strengthened and has tropical storm-force winds and has morphed from a sub-tropical storm into a tropical storm. After a United States Air Force Reserve reconnaissance flight subtropical depression seventeen was upgraded by the National Hurricane Center (NHC) to subtropical storm Otto on Oct. 6 at 5 p.m. EDT (2100 UTC). On Oct. 6 and 7, NASA's TRMM and Aqua satellites were flying overhead measuring very cold, ...

Saturn's icy moon Enceladus should not be one of the most promising places in our solar system to look for extraterrestrial life. Instead, it should have frozen solid billions of years ago. Located in the frigid outer solar system, it's too far from the sun to have oceans of liquid water -- a necessary ingredient for known forms of life -- on its surface. Some worlds, like Mars or Jupiter's moon Europa, give hints that they might harbor liquid water beneath their surfaces. Mars is about 4,200 miles across and Europa almost 2,000 miles across. However, with a diameter ...

PHILADELPHIA - Heart muscle cells do not normally replicate in adult tissue, but multiply with abandoned during development. This is why the loss of heart muscle after a heart attack is so dire—you can't grow enough new heart muscle to make up for the loss. A team of researchers at the University of Pennsylvania School of Medicine describe the interconnections between three-molecules that control fetal, heart-muscle-cell proliferation in a mouse model that will help cardiologists better understand the natural repair process after heart attacks and help scientists learn ...

CHAMPAIGN, Ill. — University of Illinois chemistry professor Alexander Scheeline wants to see high school students using their cell phones in class. Not for texting or surfing the Web, but as an analytical chemistry instrument. Scheeline developed a method using a few basic, inexpensive supplies and a digital camera to build a spectrometer, an important basic chemistry instrument. Spectrophotometry is one of the most widely used means for identifying and quantifying materials in both physical and biological sciences. "If we want to measure the amount of protein in ...

An approach pioneered by researchers at North Carolina State University gives scientists new insight into the way silicon bonds with other materials at the atomic level. This technique could lead to improved understanding of and control over bond formation at the atomic level, and opportunities for the creation of new devices and more efficient microchips. Manufacturers build silicon-based devices from layers of different materials. Bonds – the chemical interaction between adjacent atoms – are what give materials their distinctive characteristics. "Essentially, a bond ...

New Haven, Conn.—A team of Yale University scientists has engineered the cell wall of the Staphylococcus aureus bacteria, tricking it into incorporating foreign small molecules and embedding them within the cell wall. The finding, described online in the journal ACS Chemical Biology this week, represents the first time scientists have engineered the cell wall of a pathogenic "Gram-positive" bacteria—organisms responsible not only for Staph infections but also pneumonia, strep throat and many others. The discovery could pave the way for new methods of combating the bacteria ...

WEST LAFAYETTE, Ind. - A study by researchers at Purdue University suggests that some high school football players suffer undiagnosed changes in brain function and continue playing even though they are impaired. "Our key finding is a previously undiscovered category of cognitive impairment," said Thomas Talavage, an expert in functional neuroimaging who is an associate professor of biomedical engineering and electrical and computer engineering and co-director of the Purdue MRI Facility. The findings represent a dilemma because they suggest athletes may suffer a form ...

(Garrison, NY) The researcher whose revelations about unethical U.S. studies on syphilis in Guatemala in the 1940's led to apologies from the Obama administration last week has written a commentary for Bioethics Forum, the Hastings Center's online publication. She calls for the need to learn from history to better protect human subjects in the developing world. Susan M. Reverby, a professor at Wellesley College, describes how she unearthed documents about the study by accident while doing research for a book on the Tuskegee syphilis study. The documents, hidden in the ...

Talk about a walk on the wild side: University of Notre Dame researcher Joshua Shrout is co-author of a new paper that shows that bacteria are capable of "standing up" and moving while vertical. Shrout, assistant professor of civil engineering and geological sciences and a member of the Eck Institute for Global Health, has been studying the surface motility of bacteria since 2004. In 2008, UCLA researcher Gerard Wong suggested that an undergraduate bioengineering senior design group that he was advising track the bacterium Shrout was studying. After some interesting patterns ...

"Better and faster results!" is the clarion call for scientists and engineers to continually strive to improve their research tools. Of the tools used to study material structures at the atomic and molecular scales, there is none finer than Nuclear Magnetic Resonance (NMR) spectroscopy and its daughter technology Magnetic Resonance Imaging (MRI). Now, the latest development from the research group of one of the word's foremost authorities on NMR/MRI technology promises NMR/MRI results that are better and faster than ever before – a million times faster! Through a combination ...

In a study that sheds new light on the causes of Parkinson's disease, researchers report that brain cells in Parkinson's patients abandon their energy-producing machinery, the mitochondria. A shutdown in fuel can have devastating effects on brain cells, which consume roughly 20 percent of the body's energy despite making up only 2 percent of body weight. The findings indicate that boosting the mitochondria with FDA approved drugs early on may prevent or delay the onset of Parkinson's. The study will be published in the one-year anniversary issue of the journal Science ...

DURHAM, N.C. -- The cost of obesity among U.S. full-time employees is estimated to be $73.1 billion, according to a new study by a Duke University obesity researcher, published today in the Journal of Occupational and Environmental Medicine. This is the first study to quantify the total value of lost job productivity as a result of health problems, which it finds is more costly than medical expenditures. Led by Eric Finkelstein, deputy director for health services and systems research at Duke-National University of Singapore, the study quantified the per capita cost ...

The "turtle and dugong capital of the world", the northern Great Barrier Reef (GBR) and Torres Strait region, faces increased pressure under climate change from human actions such as fishing, hunting, onshore development and pollution. "Depletion of turtle and dugong numbers increases their vulnerability to other threats and lowers their ability to cope with climate change," Dr Mariana Fuentes of the ARC Centre of Excellence for Coral Reef Studies and James Cook University will tell the Coral Reef Symposium in Canberra today. Dr Fuentes says that turtles in particular ...

New York, NY, October 8, 2010—Young adults continue to represent one of the largest groups of Americans without health insurance, with nearly 15 million people aged 19-29 uninsured in 2009—an increase of more than 1 million over 2008, according to a Commonwealth Fund report released today. However, the Affordable Care Act (ACA) is poised to make a significant difference for this population, as up to 12.1 million could gain subsidized insurance once all of the law's provisions go into effect in 2014. The report, Realizing Health Reform's Potential: Young Adults and the ...
