In late February, CBS News Denver reported that mountain lion sightings were on the rise in Colorado’s high country. Lion attacks on people in the state and around the world are rare, but the story referenced an attack on a 5-year-old boy in 2016 by a mountain lion near Aspen.
Scientists from Rutgers University-New Brunswick and Atmospheric and Environmental Research (AER) have linked the frequency of extreme winter weather in the United States to Arctic temperatures.
An international collaboration between researchers at the University of Copenhagen, Nagoya University and the University of Western Australia has resulted in a breakthrough in plant biology. Since 2014, the researchers have worked on identifying the genetic background for the improved flood tolerance observed in rice, wheat and several natural wetland plants. In a New Phytologist, article, the researchers describe the discovery of a single gene that controls the surface properties of rice, rendering the leaves superhydrophobic.
In winter, cold water masses in the North Atlantic sink from the sea surface into the deep ocean. This process, known as convection, is one of the key components of the large-scale ocean circulation. Based on long-term observations, scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel have now demonstrated the influence of increased surface freshening in summer on convection in the following winter. As the researchers write now in the international journal Nature Climate Change, enhanced surface freshening and warmer winters have significantly shortened the duration of ocean convection in the last decade.
Could the LRT help reduce greenhouse effect?
A rising trend in some countries, urban rail transit systems are an alternative to freight transport through cities.
There’s a lot more snow piling up in the mountains of North America than anyone knew, according to a first-of-its-kind study.
