Collecting dust isn't usually considered a good thing.
But dust from as close as California's Central Valley and as far away as Asia's Gobi Desert provides nutrients, especially phosphorus, to vegetation in the Sierra Nevada Mountains, a team of scientists has found. Their study, published in the journal Nature Communications, highlights the importance of dust and the phosphorus it carries in sustaining plant life.
The U.S. Environmental Protection Agency (EPA) carries out experiments in which volunteer participants agree to be intentionally exposed by inhalation to specific pollutants at restricted concentrations over short periods to obtain important information about the effects of outdoor air pollution on human health. A new report by the National Academies of Sciences, Engineering, and Medicine finds these studies are warranted and recommends that they continue under two conditions: when they provide additional knowledge that informs policy decisions and regulation of pollutants that cannot be obtained by other means, and when it is reasonably predictable that the risks for study participants will not exceed biomarker or physiologic responses that are of short duration and reversible.
Climate change has dominated the news over the past 15 months. First, nearly 200 nations signed a historic accord in Paris during the COP21 climate talks in December 2015. The signatories to the accord, including the United States, the countries of the European Union, China and India, agreed to do their part to cut carbon emissions, and the Paris agreement entered into force months ahead of schedule.
BREAKTHROUGH - University of Copenhagen and the global player Bayer CropScience have successfully developed a new oilseed crop that is much more resistant to heat, drought and diseases than oilseed rape. The breakthrough is so big that it will feature as cover story of the April issue of Nature Biotechnology, the most prestigious journal for biotechnology research.
In November 2016, satellites captured a curious change in the Tereneyskoe Forest farm in Primorsky Krai, Russia. Images showed the area transformed, from nice and leafy to stark and stumpy. An Earth-monitoring company called Astro Digital noticed the change first—and right away, it informed the World Wildlife Federation. Pixels of evidence in hand, the federation could start legal action to stop the deforestation.
To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has found that wind and solar can be economically and environmentally competitive options and can contribute significantly to the rising demand.
