Calcium scans may be effective screening tool for heart disease
— 15:14 GMT | HealthA simple, non-invasive test appears to be an effective screening tool for identifying patients with silent heart disease who are at risk for a heart attack or sudden death. Coronary artery calcium scans can be done without triggering excessive additional testing and costs, according to the multi-centre EISNER (Early Identification of Subclinical Atherosclerosis by Noninvasive Imaging Research) study, led by investigators at the Cedars-Sinai Heart Institute. The findings appear in today's issue of the Journal of the American College of Cardiology…
Obesity in mid-life reduces the chance of healthy survival in women
— 15:09 GMT | HealthA new study by Harvard School of Public Health (HSPH) and Brigham and Women's Hospital (BWH) researchers has found that, among a large study population of women who lived until at least age 70, being overweight in mid-life was associated with having more health problems later in life, including multiple chronic diseases, and impaired cognitive function, physical function and mental health. Women who were lean at age 18 and maintained a healthy weight through mid-life had the best odds of achieving optimal health later in life. It is the first study to show the role adiposity may play in the overall health of women who survive to older ages…
Australian study sheds light on kidney repair and disease

ORMatE returns to NRL after nearly 2 years in Earth orbit
— 14:59 GMT | TechnologyCompleting an 18-month mission orbiting the Earth more than 6,000 times on-orbit the International Space Station (ISS), the Optical Reflector Material Experiment (ORMatE-1) returns to Washington, D.C., to NRL's Electronics Science and Technology Division to begin experiment testing and analysis…
Did Tyrannosaurus rex suffer from a common bird disease?
— 14:54 GMT | Geology and palaeontologyPalaeontologists Ewan Wolff (University of Wisconsin-Madison), Steve Salisbury (University of Queensland), Jack Horner (Museum of the Rockies) and David Varricchio (Montana State University), published new research in the open-access, peer-reviewed scientific journal PLoS ONE that found the Tyrannosaurus rex and its close relatives suffered from a potentially life-threatening infectious disease similar to one that occurs in living birds known as trichomonosis…
Rediscovering the dragon's paradise lost
— 14:49 GMT | BiologyThe world's largest living lizard species, the Komodo dragon (Varanus komodoensis), is vulnerable to extinction and yet little is known about its natural history. New research by a team of palaeontologists and archaeologists from Australia, Malaysia and Indonesia, who studied fossil evidence from Australia, Timor, Flores, Java and India, shows that Komodo Dragons most likely evolved in Australia and dispersed westward to Indonesia. The research, which also details new fossil specimens indicating the presence of a new species of giant varanid found on the island of Timor, is published 30 September in the open-access, peer-reviewed journal PLoS ONE…
Stripped down: Hubble highlights two galaxies that are losing it
— 14:44 GMT | AstronomyA newly released set of images, taken by the NASA/ESA Hubble Space Telescope before the recent Servicing Mission, highlight the ongoing drama in two galaxies in the Virgo Cluster affected by a process known as 'ram pressure stripping,' which can result in peculiar-looking galaxies. An extremely hot X-ray emitting gas known as the intra-cluster medium lurks between galaxies within clusters. As galaxies move through this intra-cluster medium, strong winds rip through galaxies distorting their shape and even halting star formation…
