...team essentially conducted two trials. In one, the scientists looked at patients who chose to initiate ART when their level of CD4 cells - infection-fighting immune cells that HIV uses to replicate and then systematically destroys - ranged between 351 and 500 cells per cubic mm of blood. These patients were compared with those who decided to defer therapy until their counts dipped below 350 cells per cubic mm, the level at which current guidelines recommend starting drug treatment...
...reasons curbing pollution can have so immediate an effect is that even a little dirt can do a lot of damage. A reduction of just 10 micrograms (10 millionths of a gram) of pollution per cubic meter of air - a degree of improvement many of the surveyed cities were able to attain during the two-decade-plus period - could extend human lifespans a full nine months. How small is 10 micrograms per cubic meter? Consider that simply by living with a cigarette smoker, you're exposed to a daily dose of 20 to 30. Pittsburgh, Pa., is one city...
...very lowest levels still saw health benefits from small improvements. The evidence isn't yet there to determine whether those benefits would continue growing until the fine-particle pollution got down to zero; one of the cities closest to that, Albuquerque, N.M., still hovers around 5 micrograms per cubic meter. But at this point, it doesn't seem that the benefits taper off. "If it continues to follow what we've observed, it appears that there are health benefits down to very low levels of exposure," says Pope. (See the Year in Health, from...
More than two weeks after the spill, workers and machines are still trying to clear the estimated 5.4 million cubic yards of coal ash from around the plant. The breach "is an environmental catastrophe that reveals not only the dangers of burning coal and mismanaging coal combustion waste, but also the need for federal regulation," said Steven Smith, executive director of the Southern Alliance for Clean Energy, at a Senate hearing on the spill on Jan. 8. After Kingston, coal may be considered many things - but it's hard to see how "clean" could be one of them...
...pays is a subsidized relic from the Cold War-era and that it is no longer offset by Ukrainian pumping services for Gazprom's clients in Europe. Gazprom wants to raise the price to $450 and also fine Ukraine's national gas company, Naftogaz, for allegedly expropriating millions of cubic meters of gas that Russia pumped through Ukraine to European clients. Naftogaz denies the diversion claims and says Moscow is using the gas issue as it has in previous years: to punish Ukraine for seeking membership in NATO and the European Union.
