Senior doctors expose 'scandal' of pacemaker battery life Posted: 04 Feb 2016 08:13 AM PST The battery life of implantable heart monitors must be improved to reduce the need for replacement and the risks this carries for patients, argue two senior doctors in a new article.

Emergency blood transfusions for major trauma need to be more rapid, consistent Posted: 04 Feb 2016 01:22 AM PST Only 2 percent of patients with life-threatening bleeding after serious injury receive optimal blood transfusion therapy in England and Wales, according to research. The study estimates that nearly 5,000 trauma patients sustain major hemorrhage in England and Wales each year and that one-third of those die. The research spotlights how delays in blood transfusion practices may contribute to this high death rate.

Investigation casts doubt over trial used to support top-selling anti-clotting drug Posted: 04 Feb 2016 01:22 AM PST An investigation raises new concerns about the top-selling anti-clotting drug, rivaroxaban (Xarelto). The trial compared rivaroxaban with the older anti-clotting drug warfarin for preventing strokes in patients with irregular heartbeat (atrial fibrillation).

For pregnant women with flu, the earlier the better for antiviral treatment Posted: 04 Feb 2016 01:22 AM PST Pregnant women are at higher risk for serious illness and complications, including death, from influenza.

Record Missouri flooding was humanmade calamity, scientist says Posted: 05 Feb 2016 02:30 PM PST Why was the New Year's flood in Missouri so bad? Most news reports blamed it on the heavy rain, but a professor of earth and planetary sciences says analysis of the flood data shows much of the damage was due to recent modifications to the river.

Many white-tailed deer have malaria Posted: 05 Feb 2016 12:33 PM PST By chance, scientists have discovered a malaria parasite that infects white-tailed deer. It's the first-ever malaria parasite known to live in a deer species and the only native malaria parasite found in any mammal in North or South America.

'Cannibalism' between stars Posted: 05 Feb 2016 11:45 AM PST Stars do not accumulate their final mass steadily, but in a series of violent events manifesting themselves as sharp stellar brightening. Stellar brightening can be caused by fragmentation due to gravitational instabilities in massive gaseous disks surrounding young stars, followed by migration of dense gaseous clumps onto the star, according to a new theory.

Cells that show where things are going Posted: 05 Feb 2016 10:49 AM PST The ability to see the direction in which something is moving is vital for survival. Only in this way is it possible to avoid predators, capture prey or, as humans in a modern world, cross a road safely. However, the direction of motion is not explicitly represented at the level of the photoreceptors but rather must be calculated by subsequent layers of nerve cells. Scientists have now discovered that, in fruit flies, four classes of nerve cell are involved in calculating directionally selective signals. This is strikingly different from mathematical models of motion detection discussed in the literature so far.

Central Appalachia flatter due to mountaintop mining Posted: 05 Feb 2016 10:49 AM PST Forty years of mountaintop coal mining have made parts of Central Appalachia 60 percent flatter than they were before excavation, researchers say.
