...conclusively linking deaths to a vaccine can be difficult, Pennington says, pointing out that there is still debate among experts as to how many of the 1976 Guillain-Barré deaths were actually caused by the vaccine. For this reason, health officials fear that adverse reactions in vaccine recipients can make the already difficult job of convincing healthy people to receive inoculations even more challenging. For whatever reason, people tend to fear vaccines more than other medicines. This has been the case since the first vaccinations were given to prevent a spread of smallpox in England in the late 18th...
This tableau demolishes one aspect of what had been conventional evolutionary wisdom. Paleoanthropologists once thought that what got our ancestors walking on two legs in the first place was a change in climate that transformed African forest into savanna. In such an environment, goes the reasoning, upright-standing primates would have had the advantage over knuckle walkers because they could see over tall grasses to find food and avoid predators. The fact that Lucy's species sometimes lived in a more wooded environment began to undermine that theory. The fact that Ardi walked upright in a similar environment many hundreds...
...knows what that reason was, but a theory about Ardi's social behavior may hold a clue. Lovejoy thinks Ar. ramidus had a social system found in no other primates except humans. Among gorillas and chimps, males viciously fight other males for the attention of females. But among Ardipithecus, says Lovejoy, males may have abandoned such competition, opting instead to pair-bond with females and stay together in order to rear their offspring (though not necessarily monogamously or for life). The evidence of this harmonious existence comes from, of all things, Ardipithecus' teeth: its canine teeth are relatively stubby compared...
...Zazi and an unspecified number of companions flew on Aug. 28 to Peshawar via Geneva and Doha. According to knowledgeable sources, something about this trip inspired U.S. officials to ask Pakistani authorities to keep an eye on Zazi, and what they saw was unsettling. "There was reason to believe that Zazi met with terrorists in Pakistan," a U.S. counterterrorism official tells TIME. The FBI confirms this, saying that since his arrest, Zazi has admitted to attending an al-Qaeda training camp, where he received instruction in weapons and explosives. "The nature of terrorist-training camps in Pakistan varies considerably...
...humanitarian and emergency affairs at World Vision, are working on technology to improve such early-warning infrastructure. Carlson, who traveled to India shortly after the 2004 tsunami, said he noticed two communities just miles apart: one was full of survivors, while the other was wiped out entirely. The reason for that difference was that the surviving village was notified by a family related to a man in Singapore who saw the tsunami warning on TV and called his family. "It was a simple phone call on a cell phone that saved hundreds of people," Carlson says. He now works...
