The water-filtering abilities of farmed kelp could help reduce marine pollution in coastal areas, according to a new University of Alaska Fairbanks-led study. The paper, published in the January issue of Aquaculture Journal, analyzed carbon and nitrogen levels at two mixed-species kelp farms in southcentral and southeast Alaska during the 2020-21 growing season. Tissue and … Read more
There are many ways to initiate chemical reactions in liquids, but placing free electrons directly into water, ammonia and other liquid solutions is especially attractive for green chemistry because solvated electrons are inherently clean, leaving behind no side products after they react. In theory, solvated electrons could be used to safely and sustainably break down … Read more
Biomedical engineers at the University of California, Davis, have created semi-living “cyborg cells.” Retaining the capabilities of living cells, but unable to replicate, the cyborg cells could have a wide range of applications, from producing therapeutic drugs to cleaning up pollution. The work was published Jan. 11 in Advanced Science. Synthetic biology aims to engineer … Read more
The 40-meter-high monitoring tower of the Innsbruck Atmospheric Observatory near the city center of Innsbruck in Austria, Europe, continuously provides data on the composition of the atmosphere near the surface. Every hour, 36,000 data points are recorded. Using a special measuring method — the so-called eddy covariance method — the concentration of air components can … Read more
Scientists have shed new light on the ‘self-cleaning’ capacity of the atmosphere. This process of self-cleaning is essential to remove gaseous pollutants and regulate greenhouse gases such as methane from the atmosphere. Researchers were already aware that the atmosphere had this ‘self-cleaning’ ability, but in a new study from the University York, experts have now … Read more
