| Sharp decline in basking shark sightings in California Posted: 22 Feb 2022 12:19 PM PST A recent study confirms a striking decrease in basking shark sightings in the California Current Ecosystem after the 1970s and 1980s and examines what is driving their presence and distribution. |
| US flood damage risk is underestimated Posted: 22 Feb 2022 12:18 PM PST Researchers found a high probability of flood damage -- including monetary damage, human injury and loss of life -- for more than a million square miles of land across the United States across a 14-year period. |
| Monitoring Arctic permafrost with satellites, supercomputers, and deep learning Posted: 22 Feb 2022 10:54 AM PST Using deep learning and supercomputers, researchers have been able to identify and map 1.2 billion ice wedge polygons in the Arctic permafrost based on satellite imagery. The data helps establish a baseline from which to detect changes to the region. The researchers trained a deep learning system to identify Arctic features and TACC's Longhorn supercomputer to analyze the data. The ice wedge data will be available for rapid analysis on the new Permafrost Discovery Gateway. |
| New technology fused with photosynthetic life offers path to green energy Posted: 22 Feb 2022 10:53 AM PST Researchers have developed a patented hybrid device -- part living organism, part bio battery, capable of producing stored energy by increasing energy flow under light conditions where natural photosynthesis is normally inhibited. |
| Posted: 22 Feb 2022 10:52 AM PST Using wildlife cameras, scientists have provided new insights through a large-scale assessment of the occurrence and distribution of the Annamite striped rabbit and two Annamite dark muntjacs in six sites in Viet Nam and Laos. The team identified factors that influence the occurrence of these threatened endemics, and provided prediction maps for these sites. |
| Scientists engineer bacteria to cope in challenging environments Posted: 22 Feb 2022 10:52 AM PST Researchers have engineered bacteria with internal nutrient reserves that can be accessed when needed to survive extreme environmental conditions. The findings pave the way for more robust biotechnologies based on engineered microbes. |
| 290 million new city dwellers benefit China's climate balance Posted: 22 Feb 2022 10:52 AM PST Contrary to popular belief, China's massive emigration from rural areas to cities has been shown to have a positive effect on China's carbon stocks. Urbanization can even play a role in attaining climate neutrality. This is the conclusion of researchers based upon analyses of vast amounts of satellite data. |
| Pine needles tell the story of PFAS in North Carolina Posted: 22 Feb 2022 10:52 AM PST The humble pine tree is more than just a common sight in North Carolina -- it's also a handy tool for monitoring the proliferation of per- and polyfluoroalkyl substances (PFAS) in our state over time. |
| Tracking the pulse of America's rivers Posted: 22 Feb 2022 10:51 AM PST Researchers are using modern sensor technology to automatically track oxygen levels and other stream vital signs 24/7, through changing seasons, floods and droughts. In a new study, researchers analyzed at least a year's worth of data from 222 rivers across the United States. The hope is that continuous tracking will get them closer to understanding the 'pulse' of streams, and how their ability to support life might change with land development and climate change. |
| Perfecting the EV battery recycling process Posted: 22 Feb 2022 10:47 AM PST Recycling of electric car batteries can be easier, cheaper, and more environmentally friendly, according to a new scientific article, which outlines an optimized recycling process. The research represents a vital step towards the electromobility society of the future. |
| Balkanatolia: The forgotten continent that sheds light on the evolution of mammals Posted: 22 Feb 2022 09:51 AM PST A team of geologists and palaeontologists has discovered that, some 50 million years ago, there was a low-lying continent separating Europe from Asia that they have named Balkanatolia. At the time, it was inhabited by an endemic fauna that was very different from those of Europe and Asia. Geographical changes 40 to 34 million years ago connected this continent to its two neighbors, paving the way for the replacement of European mammals by Asian mammals. |
| Warming climate to result in reduced corn production; irrigation blunts effect Posted: 22 Feb 2022 09:12 AM PST No matter which of the widely accepted global circulation models ultimately comes closest to predicting the amount of warming caused by climate change, corn production will be reduced, according to a new study. |
| The jet stream that brought in Storm Eunice is moving northwards Posted: 22 Feb 2022 05:56 AM PST The Northern Hemisphere Jet Stream, which this week brought storms Dudley, Eunice and Franklin to the UK has been getting faster and moving northwards over the past century. |
| Accelerating melt rate makes Greenland Ice Sheet world’s largest ‘dam’ Posted: 21 Feb 2022 12:52 PM PST The world's second-largest ice sheet is melting from the bottom up -- and generating huge amounts of heat from hydropower. |
| Government guidelines insufficient to protect freshwater ecosystem from salt pollution Posted: 21 Feb 2022 12:51 PM PST Current water quality guidelines aren't protecting freshwater ecosystems from increasing salt pollution due to road de-icing salts, agriculture fertilizers, and mining operations, according to an international study. |
| Seeing 'green' can ease confusion, anger in navigating hospitals Posted: 18 Feb 2022 02:23 PM PST Research has shown that introducing nature into large hospitals can humanize the institutional environment and reduce the stress of patients, visitors and healthcare providers. |
