...aquatic food chain - are being overfished for oil supplements. Bigger fish prey on menhaden, which eat omega-3-rich algae and in doing so clean the ocean waters off the Atlantic and Gulf coasts. By filtering up to 7 gal. (about 26 L) per min., menhaden help prevent oxygen-depleting algal blooms that lead to underwater dead zones. (See the top 10 green ideas...
...left her son's body as she found it, police were able to rule out suicide. Instead, they determined that Nicolas had accidentally killed himself playing le jeu de foulard (the "scarf game," as it's known in France), a dangerous activity in which children starve their brain of oxygen to achieve a natural high.

...normally functioning joint can withstand and actually flourish under a lot of wear," says Fries. Because cartilage - the soft connective tissue that surrounds the bones in joints - does not have arteries that deliver blood, it relies on the pumping action generated by movement to get its regular dose of oxygen and nutrients. "When you bear weight, [the joint] squishes out fluid, and when you release weight, it sucks in fluid," says Fries, explaining why a daily run or any other workout is useful for maintaining healthy cartilage...
Saving Our Forests Re "Keep the Jungle Alive" [Nov. 30]: Centuries ago Lord Buddha exhorted every individual to plant and nurture at least five trees in one's lifetime. However, governments should focus on systematic and sustainable tree plantation and conservation programs. Varieties that are indigenous, fruit bearing, oxygen enriching and medicinal should be planted instead of disorganized planting drives that just inflate numbers. A case in point is the mass planting of a eucalyptus species in India a couple of decades ago that turned out to be disastrous for water levels in some areas. Properly done, the tree bank...
Vinifying in oak can produce woody, toasty or vanillin aromas that are not desirable in every case. Making wine in stainless steel, meanwhile, can deprive it of the bouquet and tannin-ameliorating effects of a measured oxygen exposure, sometimes obliging winemakers to use artificial micro-oxygenation. The Nomblot Egg's porous clay-cement walls offer a third way, allowing for natural oxygenation without oakiness. But the tank's most surprising benefit may well lie in its shape. Creator Nomblot explains: "All fluids rise when temperature increases, and do so in a vortex, but in a barrel or other container...
