...19th century developed scrotum cancer with unusual frequency after sitting on their brushes to clean inside chimneys.In his biology of cancer course, Marshall says he learned that benzopyrene, like all compounds produced from burning organic materials, is hydrophobic.He says these facts inspired him to design a better cigarette filter, which he called ROMAR. The tip of the filter is hydrophobic, so it filters benzopyrene far more effectively than a standard filter, he says as he shows data from his preliminary tests on the device.None of Marshall’s inventions has been produced commercially, although he says he believes that...

We should establish a massive international reforestation program to reverse global warming. Ian Vincent Nairobi...

When local riot police backed by armed security forces drove tanks into the southern China village of Dongzhou on Dec. 6 and began shooting at demonstrators, there were no journalists present. Still, in this age of the Internet and cell phones, news soon began to filter out that at least six villagers had been killed.
