Many people rely on contact lenses to improve their vision. But these sight-correcting devices don't last forever and they are eventually disposed of in various ways. Now, scientists are reporting that throwing these lenses down the drain at the end of their use could be contributing to microplastic pollution in waterways. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
Scientists have shown that coastal waters and river estuaries can exhibit unique vulnerabilities to acidification than offshore waters. This acidification, detected in waters off the United States West Coast and the Gulf of Mexico, can lead to disorientation and cognitive problems in some marine fish species, such as salmon, sharks, and cod. This work is presented at the Goldschmidt Conference in Boston
Aerosols are tiny particles that are spewed into the atmosphere by human activities, including burning coal and wood. They have negative effects on air quality -- damaging human health and agricultural productivity. New work from Carnegie's Geeta Persad and Ken Caldeira demonstrates that the impact these fine particles have on the climate varies greatly depending on where they were released.
Hikmet Budak, Winifred Asbjornson Plant Sciences Chair, is one of 200 international scientists who co-published an article this week detailing the description of the genome of bread wheat. The implications of the publication include greater food security.
A University of Montana researcher has discovered that mountain pine beetles may avoid certain trees within a population they normally would kill due to genetics in the trees.
Methane released by thawing permafrost from some Arctic lakes could significantly accelerate climate change, according to a new University of Alaska Fairbanks-led study.
The University of Maryland as part of the International Wheat Genome Sequencing Consortium published findings in Science detailing the full wheat genome, the world's most widely cultivated crop. A companion paper is available in the same issue with UMD and the John Innes Centre, using this sequence to examine gene expression in wheat, specifically relating to heat, drought, and disease. This paves the way for wheat varieties adapted to climate, enhancing yields, nutrition, and sustainability.
China and UK scientists investigated the effect of model resolution on the mei-yu rainfall projection using the Hadley Centre's latest climate model, HadGEM3-GC2. The investigation highlights the need of high resolution models in future climate change projections.
Scientists investigate the different impacts of northern, tropical and southern volcanic eruptions on the tropical Pacific Sea Surface Temperature(SST). The results are useful for the mitigation and adaptation of climate change after volcanic eruptions and the associated socioeconomic impacts, and can also provide insight for understanding future SST changes induced by large volcanic eruptions.
'For me, as a functional genomics and genetics researcher, having a continuous and fully annotated sequence for each of the 21 wheat chromosomes is of paramount importance,' says Kostya Kanyuka who, with bioinformatician Rob King, represented Rothamsted Research in the IWGSC. 'This will greatly speed up our efforts on identification of agriculturally important wheat genes, including those that would help to combat major fungal diseases.'
