...atoms of oxygen, it creates carbon dioxide, the chief greenhouse gas that has kept our planet warm for billions of years - and is now, thanks to human activity, making us too warm. When we think of carbon, the first word we associate with it is emissions, a concept that evokes a tinge of illegality, as if emitting a mere molecule of CO2 were a crime. But as Eric Roston points out in his engaging new book, The Carbon Age: How Life's Core Element Has Become Civilization's Greatest Threat, C is about more than just CO2. "If you think...
...Sixty years ago, Oxfam pioneered the notion of raising cash by selling donated clothes and goods from charity shops. Now it has decided the concept needs tweaking. Most of Oxfam's 730 shops across the U.K. are slightly dowdy affairs, crammed with a wide variety of used clothes, bric-a-brac, books and CDs.

Yet the President's concept of a space-based shield against nuclear weapons-the most radical plan put forward by any Administration since the dawn of the nuclear age-has become the single most powerful force affecting Soviet-American relations. It is also becoming the chief element in an intensifying showdown, within the Administration as well...
...thing: reduce the viral load in someone infected with HIV. If a vaccine can do that, it's worth looking at more closely to figure out how it does it. "Scaling back the trial to look at a single endpoint is a concept that a number of us have championed," agrees Wayne Koff, senior vice president of research and development at the International AIDS Vaccine Initiative...
