URBANA, Ill. -- Long considered a weed in North America, Camelina sativa is increasingly valued as an oilseed crop.

Researchers at the University of Illinois are now studying its nutritional value when used as part of weanling pigs' diets.

Building a nest, laying and incubating eggs and taking care of a hungry brood are very demanding on birds´ energy budgets, so it is obviously in their interests to ensure that the young they are caring for are their own. Brood parasitism sometimes makes this a difficult proposition: strangers – either of their own kind or of another species – might want a free ride and deposit their eggs into ready-made nests. The reluctant "hosts" pay a high cost. At the very least, they waste energy on unrelated offspring, while at worst their own eggs or hatchlings are killed by parasitic chicks.

SAN DIEGO, Calif. (Dec. 10, 2013)-- Millions of people will make a resolution to quit smoking around Jan. 1, but a new study suggests an even more powerful motivator than New Year's resolutions: celebrity cancer diagnoses.

The Sirtuin family of protein deacylases has received considerable attention in recent years due to its links to longevity, diabetes, cancer, and metabolic regulation. In a new study published in the Dec. 3rd 2013 issue of Cell Metabolism, Buck Institute researchers have now identified widespread regulation of proteins involved in metabolism by the mitochondrial sirtuin, SIRT5.

Tanzania has one of the fastest growing human populations in the world. But even if there are places where the population density isn't yet that high, the number of conflicts between humans and other species is expected to rise as pressure on land areas grows.

Angela Mwakatobe, who recently defended her PhD at the Norwegian University of Science and Technology (NTNU) in Trondheim, has studied villages at various distances from Serengeti National Park in Tanzania to see how people interact with the wildlife and the best ways to protect both.

SAN ANTONIO — Results from the initial analysis of event-free and overall survival for patients enrolled in the randomized, phase III Neoadjuvant Lapatinib and/or Trastuzumab Treatment Optimization (NeoALTTO) trial are to be presented here at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10–14.

SAN ANTONIO — Women with HER2-positive breast cancer who had the highest levels of immune cells in their tumors gained the most benefit from presurgery treatment with chemotherapy and trastuzumab, according to results presented here at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10-14.

SAN ANTONIO — Combining the chemotherapy drugs docetaxel and carboplatin with the HER2-targeted therapy trastuzumab was identified to be an ideal postsurgery treatment option for patients with HER2-positive breast cancer, regardless of tumor size and whether or not disease has spread to the lymph nodes, according to results from the BETH study presented here at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10-14.

Countries and major donors are changing the way they finance maternal and child, malaria, tuberculosis and HIV/AIDS health programs in low-income countries to increase their impact.

The approach, called Results-Based Financing for Health, or RBF, pays providers or recipients of health services after pre-agreed results have been achieved and independently verified.

Among patients with obstructive sleep apnea and hypertension that requires 3 or more medications to control, continuous positive airway pressure (CPAP) treatment for 12 weeks resulted in a decrease in 24-hour average and diastolic blood pressure and an improvement in the nocturnal blood pressure pattern, compared to patients who did not receive CPAP, according to a study appearing in the December 11issue of JAMA.

Mothers get all the attention. But a study led by McGill researcher Sarah Kimmins suggests that the father's diet before conception may play an equally important role in the health of their offspring. It also raises concerns about the long-term effects of current Western diets and of food insecurity.

Charlottesville, VA (December 10, 2013). Researchers from the University of Malaya in Malaysia, with collaboration from researchers from the University of Portsmouth and the University of Oxford in the United Kingdom, announce the creation of a cost-effective two-part model of the skull for use in practicing neurosurgical techniques. The model, produced using the latest generation of multimaterial 3D printers, is composed of a variety of materials that simulate the various consistencies and densities of human tissues encountered during neurosurgery.

ATLANTA December 10, 2013—A new review highlights new developments in understanding the health effects of silica, and calls for action to reduce illness and death from silica exposure at work, including stronger regulations, heightened awareness and prevention, and increased attention to early detection of silicosis and lung cancer using low dose CT scanning.

ANN ARBOR, Mich. — In 2006, Massachusetts was on the same brink that the entire nation is on today: the brink of expanding health insurance to cover far more people than before, through government-driven, market-based reform.

NEW ORLEANS (Dec. 10, 2013) — Children with acute lymphoblastic leukemia (ALL), the most common form of pediatric cancer, can safely receive intravenous infusions of a reformulated mainstay of chemotherapy that has been delivered via painful intramuscular injection for more than 40 years, research suggests.
