Mobility challenges facing older people can now be better understood by clinicians, health care practitioners and design professionals, thanks to a new innovative software tool. Initial research findings from a research collaboration between the Glasgow School of Art and the University of Strathclyde, supported by the UK Research Councils' New Dynamics of Aging program, evaluated software which enables older people to work with professionals and suggest ways to improve their lifestyle and quality of life.

A mother's voice will preferentially activate the parts of the brain responsible for language learning, say researchers from the University of Montreal and the Sainte-Justine University Hospital Research Centre. The research team made the discovery after performing electrical recordings on the infants within the 24 hours following their birth.

A Japanese research group led by Prof. Ryusuke Kakigi and Dr. Emi Nakato, National Institute for Physiological Sciences, and Prof. Masami K Yamaguchi, Chuo University, found that there was the different hemodynamic response in the temporal cortex between infants' perceptions of their own mother and of female strangers. The presentation of mother's face elicited increased hemodynamic responses in the bilateral temporal cortex. This finding was reported in Early Human Development.

In an effort to address the critical need for data about the diversity of life on Earth, scientists from the California Academy of Sciences have spent the past year exploring some of the planet's most diverse habitats, searching for new species and creating comprehensive biodiversity maps. In 2010, they have added 113 new relatives to our family tree: 83 arthropods, 20 fishes, four corals, two sea slugs, two plants, one reptile, and one fossil mammal.

18.3 million men and women ages 50 to 64 stand to benefit from provisions in the Affordable Care Act that expand access to affordable health insurance, assure that all health insurance provides a standard comprehensive benefit, prevent insurers from denying coverage or charging higher premiums to people with pre-existing conditions, and eliminate lifetime and annual limits in health insurance policies, according to a new Commonwealth Fund report released today.

In an exciting example of international collaboration, a Qatar astronomer teamed with scientists at the Harvard-Smithsonian Center for Astrophysics and other institutions to discover a new alien world. This "hot Jupiter," now named Qatar-1b, adds to the growing list of alien planets orbiting distant stars. Its discovery demonstrates the power of science to cross political boundaries and increase ties between nations.

Hawaiians can now worry less about finding stray yellowjackets living in their Christmas trees shipped from the mainland United States, partly due to research by a US Department of Agriculture scientist and his university and state cooperators.

Research examines alcohol and drug use among Phoenix area students of Mexican heritage related to discrimination. More perceived discrimination associated with increased substance use.

How depressed young people are strongly predicts how aggressive and violent they may be or may become. Contrary to popular belief, however, exposure to violence in video games or on television is not related to serious acts of youth aggression or violence among Hispanics in the US, according to new research by Dr. Christopher Ferguson from Texas A&M International University. His findings are published online in Springer's Journal of Youth and Adolescence.

A case study from the Swedish medical university Karolinska Institutet sheds light on the pathological course of Alzheimer's disease. The brain of the first Alzheimer's patient to display amyloids demonstrable with a PET scanner has been studied, both during progression of the disease and after death.
