...more fundamental question, then, is, What causes changes in gut microbiota? Many things, says Gewirtz, including the use of antibiotics, cleaner water and improved sanitation and hygiene in general, which influences the type and amount of microbes that reside in the intestines. In the current study, scientists found that in TLR5-deficient animals, the total percentage of 150 species of bacteria in the gut was three to four times higher than in normal mice, while 125 other types of bacteria were less common. "We don't have a sense of which is more important yet - that some of those species...
...turn out from the American School's Little League game, straight into a line of tanks. "It's a parade!" says my mother gaily, hoping we children won't notice that the soldiers have their guns cocked. That night, as Soviet-made MiGs strafe the city, our gardener and cleaner Mir Ali patrols the garden with an ax and a plastic baseball bat. The next day, the radio proclaims the birth of the People's Republic of Afghanistan. Tanks are wreathed in flowers, "doubtless following the prescription of some revolutionary handbook," my father writes home. The portrait painter down...
...actually a fan of the new scoring system, the "code of points," first used in Torino. I think it's raised the level of skating skill to impressive levels in ways that don't always come across on television. The edges are sharper and deeper, the footwork is cleaner and crisper, and the spins are tighter and, frankly, more like spins than the squats some skaters were getting away with for years.

...technology used in such devastating weapons offers much potential for positive growth in the energy sector. President Obama acknowledged this possibility when he announced Tuesday that the Energy Department will give an $8.3 billion loan in order to construct two new nuclear reactors in Georgia. Nuclear energy offers a cleaner alternative to fossil fuels as an energy source, does not produce greenhouse gases, and can help decrease the United States’ carbon footprint. We applaud Obama’s initiative to explore different power sources. Yet, as nuclear energy does produce radioactive waste that is difficult and dangerous...
...energy. Recent studies have priced new nuclear power at 25 to 30 cents per kilowatt-hour, about four times the cost of producing juice with new wind or coal plants, or 10 times the cost of reducing the need for electricity through investments in efficiency. Nuclear energy is much cleaner than coal, and it provides baseload power when the wind isn't blowing and the sun isn't shining, so it sounds like a sensible way to accommodate increasing electricity demand. But it's not nearly as sensible or feasible or affordable as decreasing electricity demand altogether...
