Warming temperatures are pushing 2 chickadee species -- and their hybrids -- northward

The zone of overlap between two popular, closely related backyard birds is moving northward at a rate that matches warming winter temperatures, according to a study by researchers from the Cornell Lab of Ornithology, Villanova University, and Cornell University. The research will be published online in Current Biology on Thursday, March 6, 2014.

Obese adolescents not getting enough sleep?

Cincinnati, OH, March 6, 2014 -- Lack of sleep and obesity have been associated with an increased risk of cardiovascular and metabolic diseases in adults and young children. However, the association is not as clear in adolescents, an age group that is known to lack adequate sleep and have an overweight and obesity prevalence rate of 30% in the US. In a new study scheduled for publication in The Journal of Pediatrics, researchers found that cardiometabolic risk in obese adolescents may be predicted by typical sleep patterns.

Dr. Brenna Anderson contributes to expert series on GAS in pregnancy

Ignaz Semmelweiss made one of the most important contributions to modern medicine when he instituted hand washing in an obstetric clinic in Austria in 1847, decreasing mortality there from more than ten percent to two percent. Unfortunately, infections can still occur in pregnancy and during delivery and can have associated mortality rates of up to 30 to 50 percent if not treated quickly and properly.

Study identifies gene important to breast development and breast cancer

Significance: Understanding more about how the different types of cells in breast tissue develop improves our knowledge of breast cancer. TAZ represents a potential new target for drug therapies to treat aggressive types of breast cancer.

Background: In cancer, normal cells can become unpredictable or aggressive and thus difficult to treat with anti-cancer drugs. This is especially true in breast cancer. By identifying the genes responsible for this change in cells from breast tissue, researchers hope to identify a way to stop or reverse it.

Sickle cell trait: Neglected opportunities in the era of genomic medicine

(Boston)--While acknowledging the potential of genomics to prevent and treat disease, researchers from Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) believe it is long past due to use current scientific data and technical advances to reduce the burden of sickle cell disease (SCD), one of the most common serious single gene disorders. The work, reported as a Viewpoint in this week's Journal of the American Medical Association (JAMA), highlights the gaps in knowledge and care in terms of SCD and the need to address this issue expeditiously.

Listening to whispers at the water cooler

Just as she was about to retire, Lily Ledbetter, a production supervisor at an Alabama tire plant, learned that her employers had financially discriminated against her throughout her career. She filed suit for pay discrimination, losing due to a statute of limitations on equal-pay suits. As a result, President Barack Obama signed the Lily Ledbetter Fair Pay Act into law in 2009, drawing attention to the effects of pay secrecy on the workplace.

Strong teams attract crowds for international cricket

The strength of the team — not the promise of a close contest — is the biggest draw to crowds in international cricket, new research has found.

The findings from the study, published in the journal Applied Economics, appear to contradict previous research which suggested that attendance is largely determined by how closely matched the two teams are during a game.

Misplaced protein causes heart failure

Colchicine, a drug that's used to treat gout, has the beneficial side effect of lowering the risk of heart attack in patients taking it. Conversely, taxol, a drug for treating cancer, has the opposite effect; raising the risk of heart failure.

Computational tool offers new insight into key biological processes

Researchers from North Carolina State University have developed a computational tool designed to guide future research on biochemical pathways by identifying which components in a biological system are related to specific biochemical processes, including those processes responsible for gene expression, cell signaling, stress response, and metabolism.

Eating red and processed meat -- what do scientists say

Oxford, March 6, 2014 -- Recent reports warn about a link between eating red and processed meat and the risk of developing cancer in the gut. These reports have resulted in new nutritional recommendations that advise people to limit their intake of red and processed meats. A recent perspective paper, authored by 23 scientists, published in the latest issue of journal Meat Science underlines the uncertainties in the scientific evidence and points to further research needed to resolve these issues and improve the foundation for future recommendations on the intake of red meat.

Researchers identify a critical link between obesity and diabetes

BOSTON – It's by now well established that obesity is a major risk factor for diabetes. But what exactly is it about extra body fat that leads to insulin resistance and blood glucose elevation, the hallmarks of diabetes?

Researchers capture 'most complete' picture of gene expression in cancer cell cycle

Uncontrolled cell growth and division is a hallmark of cancer. Now a research project led by the University of Dundee has provided the most complete description to date of the gene activity which takes place as human cells divide.

Sudden cardiac death: Genetic disease ARVC more common than hitherto assumed

The genetic disease ARVC leads to sudden cardiac death and is more common than it has been hitherto assumed. This is reported by an international team of researchers headed by Prof Dr Hendrik Milting from the Heart and Diabetes Center NRW in the "European Heart Journal". The molecular biologist working at the Ruhr-Universität's clinic in Bad Oeynhausen revealed that all families who are known to be affected by the disease share the same genetic origin. There must be other families in Europe who also carry the genetic mutation but who are not yet known.

South Pacific island's earliest inhabitants relied primarily on foraging, not horticulture

Early Lapita inhabitants of Vanuatu, a South Pacific Island, ate fish, marine turtles, and wild or domestic animals, rather than relying on horticulture during early colonization, according to a study published March 5, 2014, in the open-access journal PLOS ONE by Rebecca Kinaston from University of Otago in New Zealand and colleagues.

Researchers identify target for shutting down growth of prostate cancer cells

DALLAS – March 4, 2014 – Scientists at UT Southwestern Medical Center have identified an important step toward potentially shutting down the growth of prostate cancer cells.
