Boston, MA—Accurately depicting dinosaur anatomy has come a long way since the science fiction films of the 1960s. In celebration of the American Association of Anatomists' (AAA) 125th anniversary, renowned dinosaur anatomy expert Dr. Lawrence Witmer will deliver a lecture reflecting on the AAA's first President Joseph Leidy, also a preeminent American dinosaur paleontologist, and the modernizing of prehistoric bones.

Although hip fractures in older patients are known to be a major cause of long term disability and increased risk of death, less is known about the relationship between surgical delay after hip fracture and mortality risk.

North Carolina State University researchers studying aquatic organisms called Daphnia have found that exposure to a chemical pesticide has impacts that span multiple generations – causing the so-called "water fleas" to produce more male offspring, and causing reproductive problems in female offspring.

Fragility fractures due to osteoporosis are a major cause of disability or premature death in older adults. Those at highest risk are patients who have already suffered one fragility fracture; they are at twice the risk of suffering a future fracture compared to others who have not fractured.

Nevertheless health care systems around the world are failing to identify and treat these patients, leaving them exposed to debilitating and life-threatening secondary fractures.

ANN ARBOR, MI - Consuming grapes may help protect against organ damage associated with the progression of metabolic syndrome, according to research presented Monday at the Experimental Biology conference in Boston. Natural components found in grapes, known as polyphenols, are thought to be responsible for these beneficial effects.

EAST LANSING, Mich. — A Michigan State University criminologist dug into the seamy underbelly of online credit card theft and uncovered a surprisingly sophisticated network of crooks that is unique in the cybercrime domain.

Sydney researchers have discovered a new type of immune cell in skin that plays a role in fighting off parasitic invaders such as ticks, mites, and worms, and could be linked to eczema and allergic skin diseases.

The team from the Immune Imaging and T cell Laboratories at the Centenary Institute worked with colleagues from SA Pathology in Adelaide, the Malaghan Institute in Wellington, New Zealand and the USA.

Two Spanish scientists have designed an equation that provides a highly accurate estimate of an individual's speed based on stride length. They used data from professional athletes and walking and running experiments on a beach in order to come up with the equation. The result has applications in the study of fossil trackways of human footprints.

Individual cancer cells that break away from the original tumor and circulate through the blood stream are considered responsible for the development of metastases. These dreaded secondary tumors are the main cause of cancer-related deaths. Circulating tumor cells (CTCs) detectable in a patient's blood are associated with a poorer prognosis. However, up until now, experimental evidence was lacking as to whether the "stem cell" of metastasis is found among CTCs.

COLUMBUS, Ohio – A new study led by researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) suggests that an unusual experimental drug can reduce breast-cancer aggressiveness, reverse resistance to the drug fulvestrant and perhaps improve the effectiveness of other breast-cancer drugs.

The findings of the laboratory and animal study, published in the Journal of Experimental Medicine, suggest a new strategy for treating breast cancer, the researchers say.

BOSTON—With work and entertainment operating around the clock in our modern society, sleep is often a casualty. A bevy of research has shown a link between sleep deprivation and cardiovascular disease, metabolic disorders, and obesity. However, it's been unclear why sleep loss might lead to these effects. Several studies have tested the effects of total sleep deprivation, but this model isn't a good fit for the way most people lose sleep, with a few hours here and there.

BOSTON—Up to 20 percent of veterans returning from Afghanistan and Iraq have experienced at least one blast concussion. New research suggests that nearly half these veterans may have a problem so under-recognized that even military physicians may fail to look for it. A new study conducted by Charles W. Wilkinson, Elizabeth A. Colasurdo, Kathleen F. Pagulayan, Jane. B. Shofer, and Elaine R.

DAVIS, CA, April 22, 2013 – Three new studies involving tree nuts (almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts) were presented this week at the Experimental Biology Meeting in Boston, MA. Tree nut consumption was associated with a better nutrient profile and diet quality; lower body weight and lower prevalence of metabolic syndrome; and a decrease in several cardiovascular risk factors compared to those seen among non-consumers.

NEW YORK—A massive study analyzing gene expression data from 22 tumor types has identified multiple metabolic expression changes associated with cancer. The analysis, conducted by researchers at Columbia University Medical Center, also identified hundreds of potential drug targets that could cut off a tumor's fuel supply or interfere with its ability to synthesize essential building blocks. The study was published today in the online edition of Nature Biotechnology.

Geneva, Switzerland: Giving palliative radiotherapy to elderly patients with painful bone metastases can significantly improve their quality of life, a Dutch researcher told the 2nd Forum of the European Society for Radiotherapy and Oncology (ESTRO) today (Monday).
