New dinosaur found in Portugal, largest terrestrial predator from Europe

A new dinosaur species found in Portugal may be the largest land predator discovered in Europe, as well as one of the largest carnivorous dinosaurs from the Jurassic, according to a paper published in PLOS ONE on March 5, 2014 by co-authors Christophe Hendrickx and Octavio Mateus from Universidade Nova de Lisboa and Museu da Lourinhã.

Younger men benefit most from surgery for localized prostate cancer

Boston, MA -- More than 230,000 men will be diagnosed with prostate cancer this year in the United States, but determining their course of treatment remains a source of considerable debate. A new study by researchers from Uppsala University Hospital, Sweden, Harvard School of Public Health (HSPH) and colleagues—which draws from one of the few randomized trials conducted to directly address this issue—finds a substantial long-term reduction in mortality for men with localized cancer who undergo a radical prostatectomy.

Genetic cause found for premature ovarian failure

The results, published in The New England Journal of Medicine and Human and Molecular Genetics journals, demonstrate for the first time that mutation in STAG3 gene is the major cause of human fertility disorders as it provokes a loss of function of the protein it encodes.

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.

New guidance for preventative action against diabetes

A team of academics from the University of Leicester has been instrumental in shaping National Institute for Health and Care Excellence (NICE) guidance that will influence medical policy towards diabetes prevention nationwide.

Penn team finds a new structure in dogs' eye linked to blinding retinal diseases

In humans, a tiny area in the center of the retina called the fovea is critically important to viewing fine details. Densely packed with cone photoreceptor cells, it is used while reading, driving and gazing at objects of interest. Some animals have a similar feature in their eyes, but researchers believed that among mammals the fovea was unique to primates — until now.

Researchers gain new insights into ancient Pacific settlers' diet

Researchers from New Zealand's University of Otago studying 3000-year-old skeletons from the oldest known cemetery in the Pacific Islands are casting new light on the diet and lives of the enigmatic Lapita people, the likely ancestors of Polynesians.

Look back at US soybeans shows genetic improvement behind increased yields

URBANA, Ill. – Soybean improvement through plant breeding has been critical over the years for the success of the crop. In a new study that traces the genetic changes in varieties over the last 80 years of soybean breeding, researchers concluded that increases in yield gains and an increased rate of gains over the years are largely due to the continual release of greater-yielding cultivars by breeders.

Fertility prospects following ectopic pregnancy

WINSTON-SALEM, N.C. – March 5, 2014 – Preserving a fallopian tube following an ectopic pregnancy seems like it would favor a woman's fertility prospects, right?

A new study from Wake Forest Baptist Medical Center looked at pregnancy outcomes in regards to the two surgical treatments for ectopic pregnancy -- salpingectomy, in which the affected fallopian tube is removed, or salpingotomy, in which the tube is preserved.

Study: Alzheimer's disease a much larger cause of death than reported

MINNEAPOLIS – A new study suggests that Alzheimer's disease may contribute to close to as many deaths in the United States as heart disease or cancer. The research is published in the March 5, 2014, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Applying math to cancer, climate, crime and cameras

Improving radiation therapies for cancer mathematically

In a paper published in December in the SIAM Journal on Scientific Computing, authors Li-Tien Cheng, Bin Dong, Chunhua Men, Xun Jia, and Steve Jiang propose a method to optimize radiation therapy treatments in cancer patients.

3-D changes in DNA may lead to a genetic form of Lou Gehrig's disease

New findings reveal how a mutation, a change in the genetic code that causes neurodegeneration, alters the shape of DNA, making cells more vulnerable to stress and more likely to die.

The particular mutation, in the C9orf72 gene, is the most common cause for amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease), and frontotemporal degeneration (FTD), the second most common type of dementia in people under 65.

Researchers find potential target for drug to treat allergic asthma

COLUMBUS, Ohio – An enzyme that helps maintain immune system function by "throwing away" a specific protein has a vital role in controlling symptoms of allergic asthma, new research in mice suggests.

The finding suggests that this enzyme, called Cbl-b, could be a target for drugs used to treat allergic asthma and other autoimmune disorders.

This new study, led by Ohio State University researchers, is the first to link Cbl-b to allergic asthma in an animal model.

Pumping iron: A hydrogel actuator with mussel tone

Protein from a small, tasty mollusk inspired Michigan Technological University's Bruce P. Lee to invent a new type of hydrogel actuator.

Hydrogels are soft networks of polymers with high water content, like jello. Because of their soft, gentle texture, they have the potential to interact safely with living tissues and have applications in a number of medical areas, including tissue engineering. Lee, an assistant professor of biomedical engineering, wanted to make a hydrogel that wouldn't just sit there.

Going viral to target tumors

March 5, 2014, New York, NY– A Ludwig Cancer Research study suggests that the clinical efficacy of checkpoint blockade, a powerful new strategy to harness the immune response to treat cancers, might be dramatically improved if combined with oncolytic virotherapy, an investigational intervention that employs viruses to destroy tumors.
