Diseased lungs. A sewn-up corpse of a smoker. Cigarette smoke coming out of the tracheotomy hole in a man's neck. http://phys.org/news227866971.html Medicine & Health Tue, 21 Jun 2011 09:23:11 EST news227866971 Cigarette smoking, forest fires and woodburning can release a chemical that may be at least partly responsible for human health problems related to smoke exposure, according to a new study by NOAA researchers and their colleagues. http://phys.org/news224770209.html Space & Earth Mon, 16 May 2011 15:00:05 EST news224770209 A U.S. Environmental Protection Agency draft assessment of the potential health effects associated with formaldehyde exposure needs substantial revision, says a new report from the National Research Council, which recommends improvements for EPA's final assessment. The report finds that EPA supports its conclusions that formaldehyde can cause irritation to the eyes, nose, and throat; lesions in the respiratory tract; and genetic mutations at high concentrations. Furthermore, the report finds that the evidence is sufficient for EPA to conclude that formaldehyde exposures are a cause of cancers of the nose, nasal cavity, and upper throat. However, the draft assessment has not adequately supported its conclusions that formaldehyde causes other cancers of the respiratory tract, leukemia, or several other noncancer health outcomes. Also, the assessment should consider additional studies to derive noncancer reference concentrations (RfCs), which are estimates of lifetime concentrations to which someone could be exposed without appreciable risk of particular adverse health effects. http://phys.org/news221739304.html Space & Earth Mon, 11 Apr 2011 11:15:16 EST news221739304 CO2 capture by means of amines is considered to be the most appropriate method to quickly begin with CO2 removal. During this capture process, some of the amines escaping the recycling process will be emitted into the air and will also form other compounds such as nitrosamines and nitramines. The Norwegian Institute of Public Health (NIPH) was commissioned by the Climate and Pollution Agency (Klif) to assess whether these new emissions are harmful to health - particularly in terms of the cancer risk to the general population. The results of the risk assessments were submitted recently. http://phys.org/news221131877.html Medicine & Health Mon, 04 Apr 2011 10:31:34 EST news221131877 Babies are born earlier when their mothers live near a concentration of freeways and main roads, a study of 970 mothers and their newborn babies in Logan City, south of Brisbane, has found. http://phys.org/news221127586.html Medicine & Health Mon, 04 Apr 2011 09:20:04 EST news221127586 (PhysOrg.com) -- Cornell researchers are calling on their colleagues around the world to focus on how aging global populations will intersect with climate change and calls for environmental sustainability. http://phys.org/news221122592.html Medicine & Health Mon, 04 Apr 2011 07:56:52 EST news221122592 A study presented today at the European Congress on Osteoporosis and Osteoarthritis currently taking place in Valencia, Spain has found that the initial quality of life loss following an osteoporotic fracture is substantial, especially with regard to hip and vertebral fractures.

Leukemia, probably. Too much radiation can raise the risk of developing cancer years down the road, scientists agree, and the young are most vulnerable. But just how much or how long an exposure is risky is not clear. http://phys.org/news219927818.html Medicine & Health Mon, 21 Mar 2011 13:10:22 EST news219927818 (PhysOrg.com) -- When reactive oxygen species (ROS) hit the body, vitamin E helps to prevent damage to tissues and cells by acting as an antioxidant. The health benefits of vitamin E are numerous, and in fact, studies have found that people with higher levels of vitamin E in their system have a lower risk of heart disease and certain forms of cancer. A team led by Thomas Rosenau from the University of Natural Resources and Life Sciences in Vienna (Austria) now describe their synthesis of a series of modified vitamin E derivatives that show promise as dioxin receptor antagonists in the European Journal of Organic Chemistry. http://phys.org/news219658832.html Chemistry Fri, 18 Mar 2011 09:21:36 EST news219658832 Several federal agencies, including the National Institutes of Health, today unveiled a new high-speed robot screening system that will test 10,000 different chemicals for potential toxicity.

Their study, reported in ACS's journal Environmental Science & Technology, concludes that the dust from the mud may be no more harmful than particles of ordinary urban air pollution. http://phys.org/news217083457.html Space & Earth Wed, 16 Feb 2011 12:57:59 EST news217083457 With millions of people warding off winter's chill with blazing fireplaces and wood-burning stoves, scientists are raising red flags about the potential health effects of the smoke released from burning wood. Their study, published in the American Chemical Society's (ACS') journal, Chemical Research in Toxicology, found that the invisible particles inhaled into the lungs from wood smoke may have several adverse health effects. It is among 39 peer-reviewed scientific journals published by ACS, the world's largest scientific society. http://phys.org/news216192808.html Medicine & Health Sun, 06 Feb 2011 06:03:03 EST news216192808 In the months leading up to the summer, a question that I frequently heard was "Tasmania? You're going to spend your summer in Africa?" Another popular comment was "You realize it's winter down there, right?"
