We're off then: the evolution of bat migration
Not just birds, but also a few species of bats face a long journey every year. Researchers at Princeton University in the U.S. and at the Max Planck Institute for Ornithology in Radolfzell, Germany studied the migratory behaviour of the largest extant family of bats, the so-called "Vespertilionidae" with the help of mathematical models.   view more (2009-11-24)

Intervals between lung cancer diagnosis and treatment displays a health care disparity
Research published in the November 2009 issue of the Journal of Thoracic Oncology has found that intervals between lung cancer suspicion, diagnosis and treatment may be attributed to health care system discrepancies.   view more (2009-11-02)

Wolves lose their predatory edge in mid-life, new U of Minnesota study shows

Stent for life initiative
Primary angioplasty (with stent implantation) is the most effective therapy for acute myocardial infarction (AMI), but it is not available to many patients, even though most European countries have sufficient resources (ie, catheterisation laboratories) for its wider use.   view more (2009-09-01)
