Hazardous air: What goes into your lungs on a bad day in Beijing
2013-04-23 09:20:00| Climate Ark Climate Change & Global Warming Newsfeed
Greenpeace: You have seen air pollution before, but not in this way. Beijings hazardous air is changing the energy outlook of the country, and sending a warning to other countries on the human cost of heavy reliance on coal. Beijings airpocalypse in last December and January was an exceptionally serious air pollution episode that is estimated to have caused a 3-fold increase in hospitalizations due to respiratory diseases and has drawn comparisons to London smog in 1952. In that time Greenpeace recruited...
Ozone kills by hampering gas exchange in lungs

New Scientist: We know ozone is bad for our lungs the increased risk of developing diseases such as asthma was one of the reasons people wore face masks during January's record-breaking smog in China. But exactly what it did to the lungs has never been clear. To investigate, Katherine Thompson from Birkbeck College in London and colleagues scattered neutrons off an oily surface. It was designed to mimic the fluid films on lung tissues which make the exchange of oxygen and carbon dioxide more efficient. By looking...

Probing How PRRS Affects Pig Lungs
2013-04-11 18:28:00| National Hog Farmer
Source: American Society of Animal Science Porcine reproductive and respiratory syndrome (PRRS), a devastating disease in pigs, causes significant losses to the swine industry worldwide each year. The ability of the PRRS virus to persist and evade a host’s immune response has USDA Agricultural Research Service (ARS) scientists digging deeper into the molecular and cellular mechanisms of the disease. read more

Scientists Gauge Vulnerability of Earth's "Lungs" To Climate Change
2013-02-07 19:04:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Because they draw in carbon dioxide and breathe out oxygen, tropical rainforests are often called "the lungs of the planet." However, yearly variations in climate can cause the amount of carbon dioxide absorbed and released by these forests to vary considerably. A new study conducted by a team of scientists from the University of Exeter, the Met Office-Hadley Centre and the Natural Environmental Research Councils (NERC) Centre for Ecology & Hydrology demonstrates that these variations reveal...

Lungs of the planet reveal their true sensitivity to global warming
2013-02-06 19:59:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Tropical rainforests are often called the "lungs of the planet" because they generally draw in carbon dioxide and breathe out oxygen. But the amount of carbon dioxide that rainforests absorb, or produce, varies hugely with year-to-year variations in the climate. In a paper published online Feb 6 2013 by the journal Nature, a team of climate scientists from the University of Exeter, the Met Office-Hadley Centre and the NERC Centre for Ecology & Hydrology, has shown that these variations reveal...
