A new study confirms that exposure to low to moderate amounts of arsenic in drinking water can impair lung function. Doses of about 120 parts per billion of arsenic in well water—about 12 times the dose generally considered safe—produced lung damage comparable to decades of smoking tobacco. Smoking, especially by males, made arsenic-related damage even worse. This is the first population-based study to clearly demonstrate significant impairment of lung function, in some cases extensive...

Single cell organisms need hemoglobin to survive in an oxygen-free environment When green algae "can't breathe", they get rid of excess energy through the production of hydrogen. Biologists at the Ruhr-Universität Bochum have found out how the cells notice the absence of oxygen. For this, they need the messenger molecule nitric oxide and the protein hemoglobin, which is commonly known from red blood cells of humans. With colleagues at the UC Los Angeles, the Bochum team reported in the...

Efficient Hemoglobin Key To Fish Success

Brett Smith for redOrbit.com - Your Universe Online The primordial oceans in Earth´s early days were a much more inhospitable than they are today, and new research published in the journal Science suggests that fish developed a highly efficient hemoglobin-based system to deliver large amount of oxygen to their tissues. “Four hundred million years ago the oceans were not what they are today. They were low in oxygen, high in CO2 and acidic,” said study co-author Jodie...
