...there have been violent incidents in Spain, the U.K., India, and a number of other countries where homeland security is not as good as it is in the U.S. The fact that as recently as 2004, terrorists could kill more than 170 people on the Madrid commuter railroad system is an extraordinary reminder that some parts of the social and business infrastructure in the developed world are still terribly vulnerable. The notion that terrorists could attack commuter trains going in or out of New York City is imaginable and, perhaps even possible. (Read a TIME story on 5 years after...
What is puzzling, however, is the WHO's decision to escalate the alert now, when the world has most likely missed its chance to contain the virus. When the WHO's pandemic alert system was first conceived, phase 4 was intended to indicate the moment when a new flu virus had been identified and could spread effectively from person to person (as Asia's H5N1's bird flu virus, which reached phase 3, has never been able to do), but was still limited enough that health officials could launch a global effort to contain it and snuff it out with...
...specific kind of genetic change: deletions and duplications of genes. While there are many such changes associated with autism, most are very rare. This paper, however, found an intriguing pattern among two genes already linked to autism and nine newly identified targets. Most play a role in two key systems in the brain. One is the same brain-wiring system - neural cell adhesion - implicated in the first paper. The second is a set of housekeeping proteins - the ubiquitin system - that whisk away old brain connections and set the stage for new ones...

...become a PETA acolyte, I also couldn’t shake entirely what I had seen in Vietnam. I read Matthew Scully’s beautiful book Dominion: The Power of Man, the Suffering of Animals, and the Call to Mercy and began to wonder if our meat-production system merely sanitized and institutionalized the cruelty I had seen in Vietnam. Increasingly unsettled, I made a fateful decision to visit a slaughterhouse...
