| Slow research to understand fast change Posted: 17 May 2021 11:47 AM PDT A new open-access research collection reveals unexpected lessons drawn from decades of rich data from the Long Term Ecological Research (LTER) Network. |
| Four new species of sponge that lay undiscovered in plain sight Posted: 17 May 2021 09:49 AM PDT The ocean is a big place with many deep, dark mysteries. Humans have mapped no more than 20% of the sea, and explored less. Even the kelp forests of Southern California -- among the best studied patches of ocean on the planet -- hide species not yet described by science. |
| Air quality linked to increased risk of Alzheimer's Posted: 17 May 2021 09:49 AM PDT Researchers have found a link between traffic-related air pollution and an increased risk for age-related dementia, including Alzheimer's disease. Their study, based on rodent models, corroborates previous epidemiological evidence showing this association. |
| Pollutants rapidly seeping into drinking water Posted: 17 May 2021 09:49 AM PDT Contamination risk of groundwater in karst regions is higher than previously believed. |
| Greenhouse gas and aerosol emissions are lengthening and intensifying droughts Posted: 17 May 2021 09:49 AM PDT Greenhouse gases and aerosol pollution emitted by human activities are responsible for increases in the frequency, intensity and duration of droughts around the world, according to a new study. |
| Discovery of flowering gene in cacao may lead to accelerated breeding strategies Posted: 17 May 2021 09:49 AM PDT For the first time, researchers have identified a gene that controls flowering in cacao, a discovery that may help accelerate breeding efforts aimed at improving the disease-ridden plant, they suggested. |
| Climate policies, transition risk, and financial stability Posted: 17 May 2021 07:57 AM PDT The way in which banks react to climate risks and uncertainty could impact financial stability as well as the world's transition to a low-carbon economy. A new study explored the role that banks' expectations about climate-related risks will play in fostering or hindering an orderly low-carbon transition. |
| Greenland becoming darker, warmer as its snow ages and changes shape Posted: 17 May 2021 07:57 AM PDT A reduction in the amount of fresh, light-colored snow in parts of Greenland is exposing older, darker snow. The research reports on new weather patterns and explains how the changing shape of snowflakes on the surface is leading to conditions on Greenland's ice sheet, including possibly increased melting. |
| Global land use more extensive than estimated Posted: 17 May 2021 07:26 AM PDT Humans leave their 'footprints' on the land area all around the globe. These land-use changes play an important role for nutrition, climate, and biodiversity. Scientists have now combined satellite data with statistics from the past 60 years and found that global land-use changes affect about 32 percent of the land area. This means that they are about four times as extensive as previously estimated. |
| New numerical method makes simulating landslide tsunamis possible Posted: 17 May 2021 07:26 AM PDT Researchers have developed a new numerical method that paves the way for simulating landslide tsunamis. |
| Two biodiversity refugia identified in the Eastern Bering Sea Posted: 17 May 2021 07:26 AM PDT Scientists have used species survey and climate data to identify two marine biodiversity refugia in the Eastern Bering Sea - regions where species richness, community stability and climate stability are high. |
