Imagine a world where you can eat any kind of fat you want without raising your risk of heart disease.
A new study in mice raises just that possibility.

One simple blood test could predict relapse or survival for children and young adults with acute leukemias, researchers from the Children's Cancer Hospital at The University of Texas M. D. Anderson Cancer Center reported at the American Society of Pediatric Hematology Oncology's annual meeting Saturday, May 5.
A review of young leukemia patients over the past decade has shown that the absolute lymphocyte count (ALC), a measure of normal immune cells found on every complete blood count report, is a powerful predictor of survival for young patients with leukemia.

Everyday experience and psychology research both indicate that paying close attention to one thing can keep you from noticing something else.
However, a new study from the University of Wisconsin-Madison suggests that attention does not have a fixed capacity - and that it can be improved by directed mental training, such as meditation.

Tropical plants may be more adaptable than commonly thought to changing rainfall patterns expected to accompany a warming climate, new research shows.
A University of Florida scientist and other researchers have found that plants in Hawaii have the ability to acclimate to big changes in rainfall in at least one important respect – how they get nutrients. The plants largely rely on one form of the vital nutrient nitrogen in moist areas. But in the still wetter terrain that characterizes some rainforests, they switch to another form of nitrogen that becomes more available in those conditions.

New immigrants to Western nations are believed to experience fewer chronic health problems (e.g., diabetes, high blood pressure and heart disease) than long-time residents of those countries. Dr. Joel Ray and coauthors tested whether this "healthy immigrant effect" extends to complications during pregnancy.

Implanted pumps improved heart function enough in a small percentage of patients awaiting a heart transplant that they were able to leave the hospital without a pump and without a new heart, according to a study in Circulation: Journal of the American Heart Association.
The heart-assist devices also significantly improved the cardiac function in many other heart failure patients.

Does the time of year in which a child is conceived influence future academic achievement? Yes, according to research by neonatologist Paul Winchester, M.D., Indiana University School of Medicine professor of clinical pediatrics.
Dr. Winchester and colleagues linked the scores of 1,667,391 Indiana students in grades 3 through 10 who took the Indiana Statewide Testing for Educational Progress (ISTEP) examination with the month in which each student had been conceived. The researchers found that ISTEP scores for math and language were distinctly seasonal with the lowest scores received by children who had been conceived in June through August.

Most Americans are familiar with the popular city rankings of the fattest cities, the fittest cities, the most livable cities and the most expensive cities. Now, in the first-of-its-kind survey, the American Academy of Dermatology (Academy) has identified the cities that take sun protection seriously and those that fail to make the grade despite repeated health warnings.

The growing premature birth rate in the United States appears to be strongly associated with increased use of pesticides and nitrates, according to work conducted by Paul Winchester, M.D., professor of clinical pediatrics at the Indiana University School of Medicine.

Railway sleepers made from waste plastic, including recycled bumper scrap and old computer cases could be putting in an appearance on UK railway tracks soon, writes Patrick Walter in Chemistry & Industry, the magazine of the SCI.
UK company Micron, which makes sleepers from waste polystyrene and polyethylene, has already approached UK rail track operator Network Rail with the aim of forming a partnership. Polystyrene is commonly used in disposable coffee cups, and polyethylene is more likely to be seen hanging from trees in the form of carrier bags. But the longevity of this plastic means that railway sleepers made using it can potentially last for centuries. This compares to a few decades for sleepers made from wood or concrete.

Exposure to trauma may create enough changes in the brain to sensitize people to overreact to an innocuous facial gesture years later, even in people who don’t have a stress-related disorder, says new research. It appears that proximity to high-intensity traumas can have long lasting effects on the brain and behavior of healthy people without causing a current clinical disorder. But these subtle changes could increase susceptibility to mental health problems later on.

According to a new brain study, even people who seemed resilient but were close to the World Trade Center when the twin towers toppled on Sept. 11, 2001, have brains that are more reactive to emotional stimuli than those who were more than 200 miles away.
That is the finding of a new Cornell study that excluded people who did not have such mental disorders as post-traumatic stress disorder (PTSD) or major depression. One of the first studies to look at the effects of trauma on the brains of healthy people, it is published in the May issue of the journal Emotion.
