...more people develop Type 2 diabetes in adulthood - diabetes has been diagnosed in 20% of American adults, and the vast majority have Type 2 - "more and more people are going to show significant cognitive problems," says Jacobson. "This whole area of research is going to be one of considerable importance in coming years." And studies like this one remind us that conditions like diabetes have wide-ranging effects throughout the body - and that we have only begun to pick apart some of these network connections...
...Robert Wood, chief of the Pediatric Allergy and Immunology department at Johns Hopkins Children's Center, cautions against putting too much stock in such epidemiological studies. "The reality is that the vast majority of kids - 95% plus - have no potential to get peanut allergies no matter what you do," he says, "and there's ½ % to 1% who are going to get it no matter what you do." Although the findings of the U.K.-Israel study are intriguing, he says, they apply to a very small percentage of children, and more research needs to be done to determine the true...
Despite the occasional cases of nut over-precaution, Wood thinks the public generally approaches the allergy risk with common sense. "There are definitely situations where we see a fear of the allergy that develops far out of proportion to the true risk, but for the vast majority of schools, things are mostly on balance and in perspective," says Wood, who treats some 2,000 allergy patients. Further, he says, it's important to recognize that the appropriate protective measure depends on the age group in question. "We recommend very different approaches between an early preschooler and a late-elementary schooler...
Spirit and Opportunity did just that, aiming for vast basins that have the look of land that was once submerged. Spirit soon uncovered evidence of salts in the soil, a substance that would have been abundant in Martian seas, just as it is in Earth's. Opportunity discovered deposits of BB-sized pellets - which NASA nicknamed blueberries - that are rich in hematite, a mineral that forms only in watery environments. And by pure serendipity, in 2007 a balky wheel on Spirit dug a shallow trench in the ground, revealing the presence of white silica, another indicator of water...
...black South Africans had failed so miserably at its primary task. "There are miles and miles and miles of shantytowns today, many more than before," she said. "No running water, no sewerage, nothing. There are, yes, a handful of extremely rich people whose lives have changed dramatically. But the vast majority have been left behind. Unemployment is 26%. And we have a serious crime problem, and the link is clear: people are getting fed up with this non-delivery of policies, and understandably...
