That is a neat little recycle program described in “New test traces underground forest carbon.” As fast as the CO2 comes out of the ground, the tree grabs the carbon by photosynthesis and leaves two oxygen atoms in the atmosphere. A portion of the carbon is stored until the wood rots or burns. Some carbon […]

The article says, “Logging and burning for agriculture currently claim about 1 percent of the Amazon rain forest per year.” This simply is not true. We have been hearing this and even more alarming “statistics” about Amazon deforestation for more than 20 years. Yet NASA Landsat images show that little more than 10 percent of […]

People want to know “Sharing the Health: Cells from unusual mice make others cancerfree” (SN: 5/13/06, p. 292) reported that years ago it was discovered that certain male mice eradicate cancer cells and that white blood cells from these mice make normal mice cancer resistant. It also reported that it is superpremature to look forward […]

Rod is the spoiler While I applaud the work that is looking at the biochemical correlates of aggressive and delinquent behavior, it is important to emphasize that environmental factors still predominate when we are searching for the roots of violence (“Violent Developments: Disruptive kids grow into their behavior,” SN: 5/27/06, p. 328). Although there is […]

Moo juiced? I live in Northern California, where forest-biomass power plants are common (“Radiation Redux: Forest fires remobilize fallout from bomb tests,” SN: 7/15/06, p. 38). One power plant takes the ashes that result and places them where cows forage. I’m wondering to what level of concentration this process will accumulate the cesium in organic […]

On the hoof Do cows and other domestic-herd animals really emit more methane than bison and other wild-herd animals emitted before people came along? Do grass, alfalfa, and other pasture plants remove less carbon dioxide than do forests? There were open grasslands before pastures replaced some forests. I hope the people who are researching these […]
