For 50 years, the world's soybean crop has depended on the use of cyst nematode resistant varieties of beans, but no one knew how these plants fought off the nematode pests. Now, the secrets of resistant soybean plants are finally coming to light. Surprisingly, one of the genes related to nematode resistance in soybeans also has been associated with human diseases including lymphocytic leukemia, spina bifida and cardiovascular disease, according to a team of University of Missouri researchers and their colleagues whose breakthrough was recently published in the journal ...

WASHINGTON – When learning a new language, we automatically organize words into sentences that will be both clearly understood and efficient (quick) to communicate. That's the finding of a new study reported today in the Proceedings of the National Academy of Sciences (PNAS) which challenges opposing theories on why and how languages come to be organized the way they are. With more than 5000 languages in the world, it would be easy to assume all vary endlessly, but, in fact, there is great commonality: languages follow only a few recurrent patterns. These commonalities ...

Early signs of lung cancer could be diagnosed using a simple blood test following a new discovery by scientists at the University of York. Early detection of lung cancer has been shown to save lives, but available methods for screening at-risk people are either too costly or involve invasive procedures. The latest findings, published today in the US journal Proceedings of the National Academy of Sciences, mean that a simple blood test could now be developed. Dr Dawn Coverley, who is based at the University's Department of Biology and is funded by Yorkshire Cancer Research, ...

A new Ebola virus study resulting from a widespread scientific collaboration has shown promising preliminary results, preventing disease in infected nonhuman primates using monoclonal antibodies. In this week's online edition of the Proceedings of the National Academy of Sciences (PNAS), the research team describes a proof-of-concept for using a "cocktail" of monoclonal antibodies, or mAbs, to prevent lethal disease in rhesus macaques. When administered one hour after infection, all animals survived. Two-thirds of the animals were protected even when the treatment, known ...

A new method of using adult stem cells as a model for the hereditary condition Gaucher disease could help accelerate the discovery of new, more effective therapies for this and other conditions such as Parkinson's, according to new research from the University of Maryland School of Medicine. Scientists at the University of Maryland School of Medicine reprogrammed stem cells to develop into cells that are genetically similar to and react to drugs in a similar way as cells from patients with Gaucher disease. The stem cells will allow the scientists to test potential new ...

MADISON -- Troy, the palatial city of prehistory, sacked by the Greeks through trickery and a fabled wooden horse, will be excavated anew beginning in 2013 by a cross-disciplinary team of archaeologists and other scientists, it was announced today (Monday, Oct. 15). The new expedition will be led by University of Wisconsin-Madison classics Professor William Aylward, an archaeologist with long experience digging in the ruins of classical antiquity, including Troy itself.

Graduate student Teresa Brugarolas and undergraduate ...

Soybean cyst nematode (SCN) does hundreds of millions of dollars' worth of damage each year. Matt Hudson and Brian Diers, crop sciences researchers at the University of Illinois and Andrew Bent at the University of Wisconsin, think they may have found a way to strengthen plant resistance. The research has just been published in Science Express. Diers and Hudson, with researchers at Wisconsin and the University of Nebraska, have been studying an area on chromosome 18 called Rhg1 (Resistance to H. glycines) that is known to be the location of the main source of SCN resistance. ...

COLUMBUS, Ohio – Companionship has the potential to reduce pain linked to nerve damage, according to a new study. Mice that were paired with a cage-mate showed lower pain responses and fewer signs of inflammation in their nervous system after undergoing surgery that affected their nerves than did isolated mice, suggesting that the social contact had both behavioral and physiological influences. The social contact lowered the pain response and signs of inflammation even in animals that had experienced stress prior to the nerve injury. These mice experienced a specific ...

MOUNTAIN VIEW, CA – October 15, 2012 – In a new theoretical study, 23andMe, the leading personal genetics company, developed a mathematical model which shows that family history and genetic tests offer different strengths. The study results suggest that both family history and genetics are best used in combination to improve disease risk prediction. The full results of the study have now been published online in the journal PLOS Genetics. Family history is most useful in assessing risks for highly common, heritable conditions such as coronary artery disease. However, ...

Archaeologists from the University of Leicester who uncovered a grave thought to contain the skeleton of King Richard III have revealed that the remains came within inches of being destroyed by Victorian builders. The University of Leicester led the search for the Anointed King who died at the battle of Bosworth in association with Leicester City Council and the Richard III Society. The University team dug three trenches under a Leicester car park before their discovery was made. Now site director Mathew Morris has disclosed that the remains were found just inches below ...

Exercise and healthy eating reduce body fat and preserve muscle in adults better than diet alone, according to a study funded and conducted by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health. The study was recently published online in Obesity and will be in a future print edition. NIDDK senior investigator Kevin Hall, Ph.D., analyzed the individual effects of daily strenuous exercise and a restricted diet by examining data from 11 participants from the reality television program "The Biggest Loser." ...

URBANA – Adding the right prebiotic to the diets of pediatric patients with intestinal failure could replace intravenous feeding, says a new University of Illinois study. "When we fed the carbohydrate fructooligosacharide (FOS) as a prebiotic, the gut grew and increased in function," said Kelly A. Tappenden, a U of I professor of nutrition and gastrointestinal physiology. "The study showed that using the correct pre- and probiotic in combination could enhance these results even more." When FOS enters the intestines, bacteria convert it into butyrate, a short-chain fatty ...

WINSTON-SALEM, N.C. – Oct. 15, 2012 – When patients suffering from Acute Myeloid Leukemia (AML) express high levels of the gene, MN1, an already aggressive leukemia is accelerated and shortens survival time. While that's a known fact, the mechanisms involved aren't well understood which is why a Wake Forest Baptist Medical Center researcher decided to take a closer look. Timothy S. Pardee, M.D., Ph.D., an assistant professor of hematology and oncology at Wake Forest Baptist, said that previous studies of AML have shown that when patients express high levels of the MN1 ...

The recent outbreak of meningitis in the US—and the subsequent deaths of 15 individuals—has renewed scrutiny on the contemporary practice of pharmacy compounding. The risks to patients, and associated liability risk to prescribing physicians, largely outweigh the benefits when the practice goes beyond the traditional, extemporaneous role, according to Sarah Sellers from q-Vigilance LLC and Wulf Utian from Case Western Reserve University in the US. Sellers and Utian's opinion piece appears online in the journal Drugs, published by Adis. There is a place for traditional ...

New York, NY (October 15, 2012) — Screening practices for multidrug-resistant organisms (MDROs) in intensive care units (ICUs) vary widely from hospital to hospital, according to a new study by researchers at Columbia University School of Nursing and published in the October 2012 issue of the American Journal of Infection Control. Researchers found that of the hospitals surveyed, a little more than half (59 percent) routinely screened for methicillin-resistant Staphylococcus aurea, or MRSA. Other potentially deadly MDROs were screened for far less frequently: vancomycin-resistant ...

We've all been warned not to "judge a book by its cover," but inevitably we do it anyway. It's difficult to resist the temptation of assuming that a person's outward appearance reflects something meaningful about his or her inner personality. Indeed, research shows that people tend to perceive attractive adults as more social, successful, and well-adjusted than less attractive adults, a phenomenon that's been termed the "what is beautiful is good" stereotype. But could that really be true? Are physically attractive people really just as attractive on the inside as they ...

Night work can increase cancer risk in men, according to a new study published in the American Journal of Epidemiology by a research team from Centre INRS–Institut Armand-Frappier and Centre de recherche du Centre hospitalier de l'Université de Montréal. The study is one of the first in the world to provide evidence among men of a possible association between night work and the risk of prostate, colon, lung, bladder, rectal, and pancreatic cancer and non-Hodgkin's lymphoma. "Exposure to light at night can lead to a reduced production of the sleep hormone melatonin, inducing ...

The brain's "reward system," those brain circuits and structures that mediate the experience and pursuit of pleasure, figured prominently in several studies. The studies shed light on adolescents' ability to control impulsivity and think through problems; reveal physical changes in the "social brain;" document connections between early home life and brain function in adolescence; and examine the impact of diet on depressive-like behavior in rodents. Today's new findings show that: Adolescents can throw impulsivity out the window when big rewards are at stake. The ...

NEW ORLEANS — Curtailing the imminent rise in Alzheimer's disease (AD) will require early, accurate diagnostic tests and treatments, and researchers are closer to achieving these two goals.
