Winds and changing climate converted parts of Oklahoma, Kansas, Colorado and Texas into a giant ’dust bowl’ in the 1930s. In response, the 1937 ’Shelterbelt Project’ involved the planting of trees to reduce erosion and provide relief from the biting winds that blew soil from farms and drove people west to California. Now, almost 75 years later, NASA scientists have found that planting trees also can significantly reduce carbon dioxide in the atmosphere.
Tree planting and insect control could greatly affect Earth’s greenhouse gases – those gases in the atmosphere that warm the planet – according to NASA scientists who presented their findings this December during the American Geophysical Union’s fall meeting in San Francisco.
“Planting trees on marginal agricultural lands could ’sequester’ carbon and offset at least one-fifth of the annual fossil fuel emission of carbon in the United States,” said Christopher Potter, a scientist at NASA Ames Research Center in California’s Silicon Valley. “Scientists also have found that outbreaks of plant-eating insects may be linked with periodic droughts and heat waves in North America, which can trigger large seasonal losses of carbon dioxide back to the atmosphere.” Potter added.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
