Filters Do Not Lower Mortality Rate in Most Embolism Cases
EAST LANSING, Mich. — A filter used to block clots from passing from the veins in the legs to the arteries of the lung does not improve mortality rates for most patients suffering a pulmonary embolism. However, if a patient is unstable – in shock or requires a ventilator – filters can save lives.
Furthermore, for unstable patients with a pulmonary embolism, it is crucial they receive clot-dissolving medications known as thrombolytic therapy.
The findings come from a set of three research articles on pulmonary embolism treatment published by Michigan State University’s Paul Stein in the May edition of the American Journal of Medicine. The findings are based on a study of more than two million patients suffering from the sometimes deadly clots that travel to the lungs and block arteries. (more…)
UCLA Life Scientists View Biodiversity Through a Whole New Dimension
Study of body size, feeding rates has implications for ecosystems, food supply
How can blue whales, the largest animals on the planet, survive by feeding on krill, shrimp-like creatures that are the size of a penny? According to UCLA life scientists, it’s all a matter of dimensions. (more…)
Climate Change Led to Collapse of Ancient Indus Civilization, Study Finds
A new study combining the latest archaeological evidence with state-of-the-art geoscience technologies provides evidence that climate change was a key ingredient in the collapse of the great Indus or Harappan Civilization almost 4000 years ago. The study also resolves a long-standing debate over the source and fate of the Sarasvati, the sacred river of Hindu mythology.
Once extending more than 1 million square kilometers across the plains of the Indus River from the Arabian Sea to the Ganges, over what is now Pakistan, northwest India and eastern Afghanistan, the Indus civilization was the largest—but least known—of the first great urban cultures that also included Egypt and Mesopotamia. Like their contemporaries, the Harappans, named for one of their largest cities, lived next to rivers owing their livelihoods to the fertility of annually watered lands. (more…)

Unmanned NASA Storm Sentinels set for Hurricane Study
Ah, June. It marks the end of school, the start of summer…and the official start of the 2012 Atlantic hurricane season, which got off to an early start in May with the formation of Tropical Storms Alberto and Beryl. National Oceanic and Atmospheric Administration forecasters are calling for a near-normal hurricane season this year. But whether the season turns out to be wild or wimpy, understanding what makes these ferocious storms form and rapidly intensify is a continuing area of scientific research, and is the focus of the NASA-led Hurricane and Severe Storm Sentinel (HS3) airborne mission that kicks off this summer.
Beginning in late August through early October and continuing for the next several years during the Atlantic hurricane season, NASA will dispatch two unmanned aircraft equipped with specialized instruments high above tropical cyclones in the Atlantic Ocean basin. These “severe storm sentinels” will investigate the processes that underlie hurricane formation and intensity change. NASA’s Jet Propulsion Laboratory in Pasadena, Calif., will join several other NASA centers and numerous federal and university partners in the HS3 mission. (more…)
Light Pollution Transforming Insect Communities
Street lighting is transforming communities of insects and other invertebrates, according to research by the University of Exeter.
Published in the journal Biology Letters, the study shows for the first time that the balance of different species living together is being radically altered as a result of light pollution in our towns and cities.
Believed to be increasing by six per cent a year globally, artificial lighting is already known to affect individual organisms, but this is the first time that its impact on whole communities has been investigated.
This study shows that groups of invertebrates living near to artificial lights include more predators and scavengers. This could be impacting on the survival rates of different species, having a knock-on effect on birds and mammals that rely on these species for food. The effects could be affecting entire ecosystems and even humans. (more…)
