Cold Spring Harbor, N.Y. – A new study from Cold Spring Harbor Laboratory (CSHL) offers an explanation for why our brains produce fewer and fewer neurons with age, a phenomenon thought to underlie age-related cognitive decline. The study, published as the cover story in the May 6 issue of Cell Stem Cell, suggests that this drop in production is due to the shrinking cache of adult stem cells in our brains. "It's only recently that scientists have found hard evidence for the importance of new neuron production in the adult brain's hippocampus, a region critical for memory ...

Basic scientific curiosity paid off in unexpected ways when Rice University researchers investigating the fundamental physics of nanomaterials discovered a new technology that could dramatically improve solar energy panels. The research is described in a new paper this week in the journal Science. "We're merging the optics of nanoscale antennas with the electronics of semiconductors," said lead researcher Naomi Halas, Rice's Stanley C. Moore Professor in Electrical and Computer Engineering. "There's no practical way to directly detect infrared light with silicon, but ...

Global warming is likely already taking a toll on world wheat and corn production, according to a new study led by Stanford University researchers. But the United States, Canada and northern Mexico have largely escaped the trend. "It appears as if farmers in North America got a pass on the first round of global warming," said David Lobell, an assistant professor of environmental Earth system science at Stanford University. "That was surprising, given how fast we see weather has been changing in agricultural areas around the world as a whole." Lobell and his colleagues ...

A new study identifies the mutation that underlies a rare, inherited accelerated-aging disease and provides key insight into normal human aging. The research, published by Cell Press online May 5 in the American Journal of Human Genetics, highlights the importance of a cellular structure called the "nuclear envelope" in the process of aging. "Aging is a very complex process which affects most biological functions of an organism but whose molecular basis remains largely unknown," explains Dr. Carlos López-Otín from the University of Oviedo in Spain. "Over the last few ...

TORONTO, ON – Scientists at the University of Toronto, Stanford and Columbia Universities have developed a way to measure the action and function of candidate prescription drugs on human cells, including the response of individual cells, more quickly and on a larger scale than ever before. The researchers say their "mass cytometry" technology has the potential to transform the understanding of a variety of diseases and biologic actions, and will provide a better tool to understand how a healthy cell becomes diseased. Clarifying the underlying biochemistry of cells may ...

DALLAS, May 5, 2011 – A UT Southwestern Medical Center researcher has identified the most comprehensive measurement to date of estrogen's effect on breast cancer cells, showing for the first time how immediate and extensive the effect is. The findings, published online today and in the May 13 print edition of the journal Cell, could lead to a new set of therapeutic applications and provide a model for understanding rapid signal-dependent transcription in other biological systems. "We found that estrogen signaling immediately and directly regulates a strikingly large ...

Kidney disease affects 1 in 9 US adults, and by 2020 more than 750,000 Americans will be on dialysis or awaiting kidney transplant. Despite this growing health problem, every year fewer US medical students adopt nephrology as a career, according to a review appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The review by ASN Workforce Committee Chair Mark G. Parker, MD (Division of Nephrology and Transplantation, Maine Medical Center) and colleagues highlights the declining interest of medical students in the US in nephrology. ...

A protein that helps the brain develop early in life can fight the mental fuzziness induced by sleep deprivation, according to researchers at Washington University School of Medicine in St. Louis. "It's interesting that NOTCH, a protein that plays such a prominent role in development, also has important functions in the adult brain," says senior author Paul Shaw, PhD, associate professor of neurobiology. "To our surprise, we found if NOTCH activity is boosted in the brains of sleep-deprived fruit flies, the flies can continue to stay sharp and learn after sleep deprivation. ...

Arsenic exposure and smoking each elevate the risk of disease. But when combined together, the danger of dying from cardiovascular disease is magnified, a new study finds. Exposure to high or even moderate levels of the toxin arsenic through drinking water can elevate the risk of cardiovascular disease mortality, according to a new study published in British Medical Journal. Exposed individuals who smoke were hit with a dangerous double whammy: a combined mortality risk that exceeded the influence of either factor alone. "Cigarette smoking is pervasive all over the ...

HUNTSVILLE, TX -- Researchers at Sam Houston State University and the University of Texas at Austin will team up with representatives from the criminal justice system in Houston to establish protocols to determine when sexual assault kits need to be tested by crime labs. "This is a problem-solving project that seeks to determine why so many kits are not being tested," said Dr. William Wells, who is leading the research project at Sam Houston State University. "The goal is to create appropriate solutions that can be implemented and to determine if there are ways that forensic ...

(Edmonton) The obesity problem plaguing Canadians is a story heard frequently these days. For Katerina Maximova, making connections between the rising body mass index, or BMI, among native-born Canadian versus immigrant children has been the focus of a recent study. In a journal article recently published in the Annals of Epidemiology, Maximova, an assistant professor with the School of Public Health at the University of Alberta, analyzed data from approximately 6,400 low-income children in an inner-city Montreal neighbourhood who were followed for more than five years. ...

TEMPE, Ariz. – Obesity is socially contagious, according to research published in the past few years. How it is "caught" from others remains a murky area. But findings from Arizona State University researchers published online May 5 in the American Journal of Public Health shed light on the transmission of obesity among friends and family. Shared ideas about acceptable weight or body size play only a minor role in spreading obesity among friends, according to the findings published in the article "Shared Norms and Their Explanation for the Social Clustering of Obesity." "Interventions ...

OAKLAND, Calif., May 5, 2011-- Parental exposure to bisphenol A (BPA) during pregnancy is associated with decreased birth weight of offspring, compared with offspring from families without parental BPA exposure in the workplace, according to Kaiser Permanente researchers. The observational study is published in the current online issue Reproductive Toxicology. Researchers explained that there was a greater magnitude of decrease in birth weight in children whose mothers were directly exposed to high BPA levels in the workplace during pregnancy, followed by those whose ...

Transformative changes in markets, policy and science, rather than just incremental changes in farming practices and technology, will be critical if the United States is to achieve long-term sustainability in agriculture, according to a nationwide team of agriculturists that includes a University of California, Davis, animal scientist. The team's recommendations, first published as a 2010 report by the U.S. National Research Council, appear as a Policy Forum piece in the May 6 issue of the journal Science.

The Psychological Care and Healing Treatment Center, the leading destination for people who want to have their psychological disorders fixed, now offers Panic Disorder treatment Clinic. A Panic Disorder is considered as such when a person experiences several panic attacks within a short period of time. First of all, people must know that panic attacks are not very common. In fact, some people live their lives and experience only as little as two or three panic attacks through out their lives. This is why it is very uncommon to experience or suffer from several panic ...

French researchers have reported the strongest proof yet that evidence of 'circulating tumor cells' found in samples of a patient's blood is strongly linked to poor outcomes such as a short time to disease progression. At the IMPAKT Breast Cancer Conference in Brussels, Dr François-Clement Bidard and colleagues from Institut Curie in Paris say their new findings set the scene for interventional trials designed to see if improved outcomes can be achieved by modifying treatment based on circulating tumor cell counts. "We needed to do this study to confirm data provided ...

The most comprehensive analysis yet of the epigenetic modifications present in breast cancer has revealed potentially important new ways to detect and treat the disease, Belgian researchers have reported. Epigenetics is a term used to describe modifications to the DNA molecule that affect way its code is translated into proteins. These changes include methylation, a form of chemical modification. Although researchers knew epigenetics was important in cancer, information about its exact contribution to breast carcinogenesis was scant, Dr Sarah Dedeurwaerder, from Université ...

German researchers have identified an unexpected molecular marker that predicts how sensitive hard-to-treat triple-negative breast cancers are to chemotherapy. Triple-negative breast cancers --which do not express the genes for estrogen receptor, or progesterone receptor and do not have Her2/neu overexpression or amplification-- are more aggressive than other forms of the disease and cannot be treated with endocrine or Her2 targeted therapies. At the IMPAKT Breast Cancer Conference in Brussels, PhD student Carolin Huelsewig and Dr Cornelia Liedtke from Uniklinikum Muenster ...
