COLLEGE STATION, May 8, 2013 – In a groundbreaking move that provides new insight into avian evolution, biology and conservation, researchers at Texas A&M University have successfully sequenced the complete genome of a Scarlet macaw for the first time.

The team was led by Drs. Christopher Seabury and Ian Tizard at the Schubot Exotic Bird Health Center in the College of Veterinary Medicine & Biomedical Sciences at Texas A&M. Their work is published in the current issue of the open access and peer-reviewed scientific journal PLOS ONE.

COLLEGE STATION, May 13, 2013 – The tiniest bones in the human body – the bones of the middle ear – could provide huge clues about our evolution and the development of modern-day humans, according to a study by a team of researchers that include a Texas A&M University anthropologist.

EAST LANSING, Mich. -- Remains of endangered Hawaiian petrels – both ancient and modern – show how drastically today's open seas fish menu has changed.

A research team, led by Michigan State University and Smithsonian Institution scientists, analyzed the bones of Hawaiian petrels – birds that spend the majority of their lives foraging the open waters of the Pacific. They found that the substantial change in petrels' eating habits, eating prey that are lower rather than higher in the food chain, coincides with the growth of industrialized fishing.

Countries in which girls are commonly married before the age of 18 have significantly higher rates of maternal and infant mortality, report researchers in the current online issue of the journal Violence Against Women.

Environments containing species that are distantly related to one another are more productive than those containing closely related species, according to new research from the University of Toronto Scarborough (UTSC).

The experimental result from Marc William Cadotte confirms a prediction made by Charles Darwin in On the Origin of Species, first published in 1859. Darwin had said that a plot of land growing distantly related grasses would be more productive than a plot with a single species of grass.

Researchers have identified the dose of dengue virus in human blood that is required to infect mosquitoes when they bite. Mosquitoes are essential for transmitting the virus between people so the findings have important implications for understanding how to slow the spread of the disease.

By defining the threshold of the amount of virus needed for transmission, the research also provides a target that experimental dengue vaccines and drugs must prevent the virus from reaching in order to be successful at preventing the spread of disease during natural infection.

Scientists at Imperial College London have identified four new proteins that act as receptors for an essential signalling molecule in bacteria such as MRSA.

The receptors are thought to play an important role in enabling bacteria to respond to their environment. Their discovery provides scientists with vital clues in the hunt for new antibiotics, which are increasingly in need as bacteria become resistant to existing treatments.

The impact of industrial fishing on coastal ecosystems has been studied for many years. But how it affects food webs in the open ocean―a vast region that covers almost half of the Earth's surface―has not been very clear. So a team of Smithsonian and Michigan State University scientists and their colleagues looked to the ancient bones of seabirds for answers, revealing some of the dramatic changes that have happened within open-ocean food webs since the onset of industrial fishing. The team's research is published this week in the Proceedings of the National Academy of Sciences.

CHICAGO (May 13, 2013) – New research from the Centers for Disease Control and Prevention (CDC) estimates that as many as 200,000 central line-associated bloodstream infections (CLABSIs) have been prevented among patients in intensive care units (ICUs) since 1990. The study, published in the June issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America, suggests that this progress is likely related to prevention strategies now common in hospitals across the United States.

COLUMBUS, Ohio – A study has identified microRNA-155 as a new independent prognostic marker and treatment target in patients with acute myeloid leukemia that has normal-looking chromosomes under the microscope (that is, cytogenetically normal acute myeloid leukemia, or CN-AML).

In a landmark cancer study published online in Nature, researchers at NYU School of Medicine have unraveled a longstanding mystery about how pancreatic tumor cells feed themselves, opening up new therapeutic possibilities for a notoriously lethal disease with few treatment options. Pancreatic cancer kills nearly 38,000 Americans annually, making it a leading cause of cancer death. The life expectancy for most people diagnosed with it is less than a year.

NEW YORK (May 13, 2013) -- A soon-to-be-tested class of drug inhibitors were predicted to help a limited number of patients with B-cell lymphomas with mutations affecting the EZH2 protein. However, a research team, led by investigators at Weill Cornell Medical College, now report that these agents may, in fact, help a much broader cross section of lymphoma patients.

The study, reported in Cancer Cell, found that the EZH2 protein the drug agents inhibited is a powerful regulatory molecule in B-cells, and a key driver of cancer in these immune cells.

For adults with no apparent symptoms of depression, routine screening is not recommended in primary care settings because of the lack of high-quality evidence on the benefits and harms of screening for depression, according to new evidence-based guidelines from the Canadian Task Force on Preventive Health Care (CTFPHC) published in CMAJ (Canadian Medical Association Journal).

People are worse at predicting whether a sports team will win, lose, or tie when they bet on the final score than when they bet on the overall outcome, according to a new study published in Psychological Science, a journal of the Association for Psychological Science.

Examining sports betting data from both the real world and the lab, psychological scientist Kwanho Suk and colleagues at Korea University Business School found that people who relied on more detailed information were actually less accurate in their predictions about sports match outcomes.

Researchers from Uppsala University in Sweden can now reveal the mechanism behind the curved path of a curling stone. The discovery by the researchers, who usually study friction and wear in industrial and technical applications, is now published in the scientific journal Wear.
