The discovery of a major player in the body's regulation of iron levels should provide a new target for drugs that prevent common iron deficiency as well as rare, potentially deadly iron overload, researchers said.

Investigators at Sanford-Burnham Medical Research Institute (Sanford-Burnham) have discovered a new way the cell surface protein, CD44, helps specific T helper (Th1) cells develop immunologic memory.

The methodology and evidence behind a widely publicized change in national mammography guidelines is questionable, according to a review in the Journal of Diagnostic Medical Sonography (JDMS), published by SAGE.

Children with autism would likely receive better treatment if supporters of the two major teaching methods stopped bickering over theory and focused on a combined approach, a Michigan State University psychologist argues in a new paper.

A new study by researchers at UCLA and Brigham and Women's Hospital in Boston suggests that improvements in air quality over the past decade have resulted in fewer cases of ear infections in children.

A study of animals visible to the naked eye and living in and on the seabed - the 'macrobenthos' - of the Straits of Magellan and Drake Passage will help scientists understand the biodiversity, biogeography and ecology of the Magellanic region.

The number of bee colonies in Central Europe has decreased over recent decades. In fact, the number of beekeepers has been declining in the whole of Europe since 1985. This is the result of a study that has now been published by the International Bee Research Association, which for the first time has provided an overview of the problem of bee colony decline at the European level.

The study, which was published in the International Journal of Geriatric Psychiatry and funded by the National Health Research Institutes of Taiwan, tested two separate intervention methods to assess the eating patterns of dementia patients in Taiwan.

An experimental vaccine developed using non-infectious virus-like particles (VLP) has protected macaques and mice against chikungunya virus, a mosquito-borne pathogen that has infected millions of people in Africa and Asia and causes debilitating pain, researchers at the National Institutes of Health have found.

In an acute viral infection, most of the white blood cells known as T cells differentiate into cells that fight the virus and die off in the process. But a few of these "effector" T cells survive and become memory T cells, ensuring that the immune system can respond faster and stronger the next time around.

Scientists have long studied how atoms and molecules structure themselves into intricate clusters. Unlocking the design secrets of Nature offers lessons in engineering artificial systems that could self-assemble into any desired form.
