Still, on blogs run by moms of children with nut allergies, there is a consistent rallying cry for nut-free zones. The concern is airborne nut dust, which can be inhaled, or oily nut residues that can come into contact with children's skin. Wood, who has been allergic to nuts all his life, says these parents' worries may be exaggerated. The danger may depend on the severity of the allergy, but it has much more to do with the degree of contact, he says. "Nut oils or the kinds of things that might be in a classroom...
...dust in the air, Wood says it can cause severe reactions - but only under specific circumstances, with high concentrations of nut dust in a confined space. At a baseball game, for example, where nut dust is quickly dispersed in the air, the risk of an allergic reaction is low. But if you linger in the small waiting room of a restaurant with a dish of nuts and servers who keep passing through with plates of nuts, your risk of an allergic reaction is higher, he says...
...years ago, when a Yellowstone "supervolcano" exploded so violently that it created the caldera itself. Today, such an explosion - 1,000 times more powerful than the explosion of Mount St. Helens in 1980 - would not only cover most of the U.S. with ash but also throw so much dust into the atmosphere that the world's climate could change...
...Space dust, magnetic storms, solar winds and the Earth's atmosphere all create drag, which slows down the planet. Even the amount of snow covering the polar ice caps adds to the rotational lag. But one of the main obstacles is tidal friction. Because the gravitational pull between the moon and the Earth is not uniform, the tidal force stretches the Earth - core, mantle, crust, oceans and all - producing bulges. The Earth's rotation pushes the tidal bulge slightly ahead of the Earth-moon alignment; the moon's gravity, however, yanks the bulges back to keep them in line. This...
...blood shed in the past four days in the hope of changing Gaza's political equation, when the dust settles and the bodies are buried, the wider regional equation is unlikely to change fundamentally - at least not in the favor of those who would prefer to see Hamas eliminated...
