Bush meat can be a viral feast
Monkeys and apes are considered edible game in many parts of Africa. As Africans have emigrated to other parts of the world, some have retained their love of this so-called bushmeat. A new study now finds that even when smoked, meat from nonhuman primates — from chimps to monkeys — can host potentially dangerous viruses. Smuggled imports confiscated at U.S. airports provided the samples tested in this investigation.

Insurance payouts point to climate change
Natural disasters in 2011 exerted the costliest toll in history — a whopping $380 billion worth of losses from earthquakes, floods, tornadoes, hurricanes, wildfires, tsunamis and more. Only a third of those costs were covered by insurance. And the tally ignores completely any expenses associated with sickness or injuries triggered by the disasters. And except for quake-related events, climate change appears to have played a role in the growing cost of disasters, insurers said.
