Scientists at the Children's Hospital of Philadelphia report in two studies that parents can significantly reduce the accident rate among teens simply by talking with them about driving and enforcing rules for safety - much the way, as has been shown, parents can reduce the risk of substance abuse through conversations about alcohol and drugs. In fact, driving should be considered as dangerous as alcohol and drugs, the scientists say. In 2005, the latest year for which the government has statistics on teen driving, adolescent deaths made up 12% of all deaths from car accidents, and 400,000 teens required...
...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...
...there is currently not enough H1N1 vaccine to inoculate all Americans, officials are worried that frontline health workers, who should be among the first in line for the injections, might refuse over safety concerns. That could compromise health workers' ability to treat patients who are hospitalized with the disease. A study of 11 focus groups conducted in Canada prior to the H1N1 outbreak found that health-care workers might refuse to immunize their children and themselves if they believed the risks of a new vaccine outweighed the benefits, according to a report in the Emergency Health Threats Journal in August...
...environmental groups supported it, happy to see a bill with a tighter short-term emissions-reduction target. But the bill still has plenty of holes for a piece of legislation that has been in the works for months, saying little about how allowances for carbon emissions would be distributed among polluting industries - a key part of any cap-and-trade bill. And with natural gas fans blaming the bill for having too little support of natural gas and nuclear fans saying there's not enough support of nuclear, gathering up support from Republican Senators and even Democrats will...
...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...
