A team of scientists from Hokkaido University has suggested that marimo maintain their characteristic spherical shape due to the rarity of the formation of reproductive cells.
Decarbonizing US electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A generator-level model described in the December 4, 2020 issue of the journal Science suggests that most fossil fuel power plants could complete normal lifespans and still close by 2035 because so many facilities are nearing the end of their operational lives.
Machine learning tool can also calculate the optical properties of a known structure; CUORE experiment in Italy is designed to find theorized process called neutrinoless double-beta decay
Electronic tags released in the Ganges river show plastic pollution can travel thousands of kilometres in just a few months.
A new study demonstrates the potential for plastic bottles tagged with tracking devices to deepen our understanding of how plastic pollution moves through rivers. Emily Duncan of the University of Exeter, U.K., and colleagues present this research in the open-access journal PLOS ONE on Dec 2, 2020.
Cleaning surfaces with hydrogen peroxide-based disinfectants has the potential to pollute the air and pose a health risk, according to research led by University of Saskatchewan (USask).
New international research by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) warns that green energy projects can be as socially and environmentally conflictive as fossil fuel projects. While renewable energies are often portrayed as being environmentally sustainable, this new study cautions about the risks associated with the green energy transition, arguing for an integrated approach that redesigns energy systems in favor of social equity and environmental sustainability.
Humans are exposed to various environmental or dietary molecules that can attenuate or even increase the effect of therapeutic drugs. Studies on the industrial chemical bisphenol A and the phytoestrogen genistein, for example, have shown drug-exposome interactions. However, interactions between exposures and therapeutic agents have not been systematically investigated to date, conclude chemists Benedikt Warth and Manuel Pristner at the University of Vienna in a review article published in 'Trends in Pharmacological Sciences'.
In collaboration with the Technical University of Denmark (DTU), the Department of Engineering at Aarhus University has developed photonic sensor technology that can pave the way for a portable, reliable and, above all, inexpensive device for detecting ammonia and other gases in agriculture. The new technology has been developed as part of the Ecometa project, which has received DKK 12.5 million funding from Innovation Fund Denmark.
More frequent exposure to air pollution spikes were associated with reduced test scores for third graders in Salt Lake County. Schools with a higher proportion of students of color and from households experiencing poverty were exposed to more peak pollution days than were schools serving middle- to upper- class and predominately white students. The results stress the need for legislators to enact policies to reduce the number of peak pollution days.
