Trees Save Lives, Reduce Respiratory Problems

While trees' pollution removal equated to an average air quality improvement of less than 1 percent, the impacts of that improvement are substantial. Researchers valued the human health effects of the reduced air pollution at nearly $7 billion every year.

In the first broad-scale estimate of air pollution removal by trees nationwide, US Forest Service scientists and collaborators calculated that trees are saving more than 850 human lives a year and preventing 670,000 incidents of acute respiratory symptoms. While trees’ pollution removal equated to an average air quality improvement of less than 1%, the impacts [...]

New Device Detects Deadly Lung Disease

A scientist from the University of Exeter has developed a simple, cheap and highly accurate device for diagnosing a frequently fatal lung disease which attacks immune deficient individuals such as cancer patients and bone marrow transplant recipients. The lateral-flow device (LFD), created by Professor Chris Thornton, detects invasive pulmonary aspergillosis, a notoriously difficult to diagnose [...]

Drug Approved To Treat Rare Disorder Associated With Anesthesia

“When a patient experiences malignant hyperthermia during surgery, it is a life‐threatening emergency requiring immediate treatment including the administration of the ‘antidote’ drug dantrolene sodium,” said Henry Rosenberg, MD, CPE, a founder and President of the Malignant Hyperthermia Association of the United States (MHAUS). “The ability for healthcare professionals in hospitals and surgery centers to more quickly prepare and administer this new formulation of the antidote dantrolene sodium is expected to bring the crisis under control more rapidly and prevent severe complications from MH.” Source: MHAUS

Eagle Pharmaceuticals, Inc. today announced the US Food and Drug Administration (FDA) has approved Ryanodex® (dantrolene sodium) for injectable suspension indicated for the treatment of malignant hyperthermia (MH), along with the appropriate supportive measures. MH is an inherited and potentially fatal disorder triggered by certain anesthesia agents in genetically susceptible individuals. FDA had designated Ryanodex [...]

The Heart Of An Astronaut, Five Years On

The heart of an astronaut is a much-studied thing. Scientists have analyzed its blood flow, rhythms, atrophy and, through journal studies, even matters of the heart. But for the first time, researchers are looking at how oxidative stress and inflammation caused by the conditions of spaceflight affect those hearts for up to five years after [...]

On July 5, 2011, a massive wall of dust, (“haboob,” in Arabic), blanketed Phoenix, Arizona, creating an awesome spectacle, (or stubborn nuisance, depending on your perspective). Dust storms are a common occurrence in the arid desert environments of the American Southwest. But windborne dust can be a serious health risk, lofting spores of a sometimes-lethal [...]
