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.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
