| Cooperation rewards water utilities Posted: 19 May 2022 07:38 AM PDT Inter-utility water agreements can help mitigate risks, in research that used supercomputer simulations of water supply in the North Carolina Research Triangle. Findings are generalizable to any place where water providers face financial and supply challenges in allocating regional water. |
| Unlocking the secrets of killer whale diets and their role in climate change Posted: 19 May 2022 07:38 AM PDT Researchers have discovered new clues to understand how killer whales impact their environment. |
| Why baby leatherback marine turtles can't 'see the sea' Posted: 19 May 2022 07:38 AM PDT For most sea turtles, the journey to find the ocean from their nests is pretty straightforward. However, leatherback hatchlings more often crawl around in circles trying to find the ocean. Circling delays their entry into the ocean, wastes energy, and places them at greater danger from natural predators. Under different moon phases: bright light during full moon and only starlight under new moon, researchers have a better understanding of why this circling behavior happens and why it is most commonly observed in leatherbacks. |
| Satellite monitoring of biodiversity moves within reach Posted: 19 May 2022 05:11 AM PDT Global biodiversity assessments require the collection of data on changes in plant biodiversity on an ongoing basis. Researchers have now shown that plant communities can be reliably monitored using imaging spectroscopy, which in the future will be possible via satellite. This paves the way for near real-time global biodiversity monitoring. |
| Puzzling features deep in Earth's interior illuminated Posted: 19 May 2022 05:11 AM PDT New research examines an unusual pocket of rock at the boundary layer with Earth's core, some three thousand kilometers beneath the surface. |
| Sparking sustainable new chemical catalysts Posted: 18 May 2022 01:06 PM PDT New research could lead to the creation of new, sustainable catalysts based on tungsten oxide and similar compounds. The project used computational simulations to understand how tungsten oxide interacts with hydrogen at the molecular level and the findings were verified through lab experimentation. |
| How plants colonize the base of an active stratovolcano Posted: 18 May 2022 11:07 AM PDT New research in plants that colonized the base of an active stratovolcano reveals that two simple molecular steps rewired nutrient transport, enabling adaptation. |
| For wetland plants, sea-level rise stamps out benefits of higher CO2 Posted: 18 May 2022 11:07 AM PDT Wetlands across the globe are in danger of drowning from rising seas. But for decades, scientists held out hope that another aspect of climate change -- rising carbon dioxide (CO2) -- could trigger extra plant growth, enabling coastal wetlands to grow fast enough to outpace sea-level rise. That helpful side effect is disappearing, scientists have discovered. |
| Scientists hone long-range forecasting of US tornadoes, hail Posted: 18 May 2022 08:39 AM PDT New research identifies three specific orientations of atmospheric phenomena occurring near the equator over the Maritime continent that increase the probability of severe U.S. weather events three to four weeks later. |
| On the road to cleaner, greener, and faster driving Posted: 18 May 2022 08:38 AM PDT Researchers have developed a technique to control a fleet of autonomous vehicles as they approach and pass through a signalized intersection in a way that reduces fuel consumption and greenhouse emissions from idling and stop-and-go traffic, while improving travel speeds. |
| Rainforest trees may have been dying faster since the 1980s because of climate change Posted: 18 May 2022 08:38 AM PDT Tropical trees in Australia's rainforests have been dying at double the previous rate since the 1980s, seemingly because of climate impacts, according to the findings of a long-term international study. This research has found the death rates of tropical trees have doubled in the last 35 years, as global warming increases the drying power of the atmosphere. |
| Oat reference genome: Insights into a uniquely healthy cereal crop Posted: 18 May 2022 08:38 AM PDT Cultivated oat (Avena sativa L.) is an old crop thought to have been domesticated over 3,000 years ago, while growing as a weed in wheat and barley fields. Oat has a low carbon footprint, substantial health benefits and the potential to replace animal-based food products. However, lack of genome resources has prevented the application modern methods of plant breeding. An international research team now presents a high-quality reference genome of A. sativa and its most closely related wild relatives. |
| Scallops swim into illuminated fishing pots Posted: 18 May 2022 07:18 AM PDT Scallops are drawn to illuminated fishing pots like moths to a flame. The study examined the effect of LED lights on crab and lobster pots used by fishing boats off the coast of Cornwall, UK, and the research team was stunned by the results. More than 500 scallops were caught -- 99.6% of them in pots with lights. |
| At-risk sea life in the Atlantic needs better protection from an increase in shipping Posted: 18 May 2022 07:18 AM PDT New research has shown a dramatic increase in shipping in the North East Atlantic. Scientists now warn that more monitoring in the area is required to help protect sea life on the at-risk register. |
| Bringing order to the chaos of sea level projections Posted: 18 May 2022 07:17 AM PDT In their effort to provide decisionmakers with insight into the consequences of climate change, climate researchers are bringing order to the large amount of sea level projections, translating climate models to expected sea level rise. |
| Posted: 18 May 2022 05:04 AM PDT A new study has found contaminants, banned decades ago, are still imperiling critically endangered California condors. The condors may be at increased risk for reproductive impairment because they consume dead marine mammals along the California coast. |
| High rates of landscape degradation not product of landscape fires Posted: 18 May 2022 05:03 AM PDT Once humans discovered how to tame fire, they began using it for heat, cooking, to scare away animals and to alter their environs, especially burning areas to plant and to restore grazing land. In Madagascar, scientists and conservationists have long believed that fire is a leading cause of high landscape degradation, but an international team of researchers have found that medium to large fires on the island are similar to those on other tropical locations. |
| Climate change will force big shift in timing, amount of snowmelt across Colorado River Basin Posted: 17 May 2022 06:04 PM PDT New research predicts that changes in mountain snowmelt will shift peak streamflows to much earlier in the year for the vast Colorado River Basin, altering reservoir management and irrigation across the entire region. |
| Scientists see signs of traumatic brain injury in headbutting muskox Posted: 17 May 2022 10:07 AM PDT Scientists saw for the first time hallmarks of concussions and other head trauma in the brains of deceased headbutting animals -- muskoxen and bighorn sheep. The results may contradict the commonly-held belief that ramming animals do not suffer brain injuries and support the notion that studies on animals with brains evolutionarily similar to those of humans may help researchers understand and reduce traumatic brain injuries. |
| Where were Herod the Great's royal alabaster bathtubs quarried? Posted: 17 May 2022 06:48 AM PDT A new study allows for the first time the distinction between calcite-alabaster originating in Israel from that originating in Egypt. Furthermore, it confirms that calcite-alabaster objects, such as Herod the Great's alabaster bathtubs, were quarried in Israel rather than Egypt. |
| Posted: 13 May 2022 07:35 AM PDT Mercury pollution is a global problem in water, air and soil near goldmines, cement and other heavy industries burning fossil fuels -- with removal too expensive or difficult in some of the poorest countries in the world. Now experts have expanded testing of a sustainable extraction material capable of absorbing almost all mercury in polluted water in minutes -- itself made entirely from low-cost waste from the petroleum, citrus and agricultural production. |
