Published in the journal Cell Host & Microbe, the findings center around one gene variation that blocks a receptor from being expressed on the surface of red blood cells. Scientists had previously studied this genetic variant - found almost exclusively in Africans and their descendants - because it also conferred protection against an early form of malaria. (The malaria parasite needed the receptor to infect blood cells; without the receptor, the parasite starved and died.) More than 90% of sub-Saharan Africans lack the red-blood-cell receptor, along with two-thirds of African-Americans. But the variant that once saved its carriers...
...biologist to understand the importance of corals - just ask any diver. The tiny underwater creatures are the architects of the beautiful, electric-colored coral reefs that lie in shallow tropical waters around the world. Divers swarm to them not merely for their intrinsic beauty, but because the reefs play host to a wealth of biodiversity unlike anywhere else in the underwater world. Coral reefs are home to more than 25% of total marine species. Take out the corals, and there are no reefs - remove the reefs, and entire ecosystems collapse...
...leaders of the world's 16 biggest carbon emitters have sat down to talk about climate change?will be remembered as a lost opportunity. First of all, the 2050 pledge doesn't specify a baseline year. European leaders want to bring emissions down to 50% of 1990 levels, but host nation Japan seemed to indicate that it would be happy to use present-day levels. The difference in actual reductions would be enormous. So what appears to be a firm numerical target is just more hot aspirations?not too different from the original U.N. Framework Convention on Climate Change, which...

...that bluster makes him seem more like a telemarketer or talk-show host than a politician, and he tells me he'd at least like to get a nationally syndicated radio show out of this presidential campaign. It would be a mistake, though, to write Root off. The things he cares about--being able to gamble legally via his home computer, continuing to homeschool his kids without much interference, keeping taxes low--speak to a lot of Americans. If the old party was cobbled together from hard-line strains of voluntarianism, propertarianism and paleolibertarianism, the new Libertarian Party is more...
