Air Pollution Causes Sperm Mutations In Mice 53

Reservoir Hill writes "Epidemiological studies in humans have suggested a link between air pollution and reduced male fertility, but such studies are often confounded by other lifestyle differences such as diet, genetic background, and economic class. Now a study of mice, reared in cages kept in a shed downwind of two steel mills and a busy highway in a Canadian city, showed a host of genetic changes compared to similarly housed mice breathing filtered air. DNA in the sperm of the mice in the polluted area contained 60% more mutations, had more strand breaks, and had more bases that had been chemically modified via the addition of a methyl group. Precisely how the pollution caused the DNA damage remains unclear but changes may be a more general response to particulate pollution. 'It's important to move this forward to the next step: determining whether there are any human corollaries to this,' says Jonathan Samet, an epidemiologist at Johns Hopkins University."
It's funny.  Laugh.

Realtime ASCII Goggles 331

jabjoe writes "Russian artists from Moscow have created goggles with realtime image filtering. Among the Photoshop-like filters that can be applied is, interestingly, ASCII: you can view the world in real time as ASCII. Pointless but cool."
