| Large-scale ocean sanctuaries could protect coral reefs from climate change Posted: 12 May 2022 01:41 PM PDT Earth's oceans are home to some of the most diverse ecosystems on the planet, but warming temperatures are causing many marine animals, including coral, to die out. |
| Posted: 12 May 2022 01:41 PM PDT The declining body size of North Atlantic right whales may have critical consequences for the future of the species. New research shows that smaller females produce fewer calves. |
| Hunga volcano eruption provides an explosion of data Posted: 12 May 2022 01:40 PM PDT The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also created an atmospheric pulse that caused an unusual tsunami-like disturbance that arrived at Pacific shores sooner than the actual tsunami. |
| What we're still learning about how trees grow Posted: 12 May 2022 11:43 AM PDT A new study finds that tree growth does not seem to be generally limited by photosynthesis but rather by cell growth. This suggests that we need to rethink the way we forecast forest growth in a changing climate, and that forests in the future may not be able to absorb as much carbon from the atmosphere as we thought. |
| Water makes tree branches droop at night Posted: 12 May 2022 09:19 AM PDT Terrestrial laser scanning data show that trees move their branches in a diurnal pattern, settling down for the night -- as if falling asleep. Changes in the water status of leaves and branches causes branches to move downward at night, up to 20 cm depending on the tree species. |
| The deadly impact of urban streets that look like highways Posted: 12 May 2022 09:19 AM PDT Serious auto crashes in urban areas are more likely on city streets that look to drivers like highways, new research suggests. The study used a novel approach: researchers applied machine learning techniques to analyze more than 240,000 images of road segments in Columbus, Ohio. |
| Unusually fast beaked whale has special deep-sea hunting strategy Posted: 12 May 2022 09:19 AM PDT Biologists have successfully used biologgers to reveal insights into the lifestyle and hunting behaviur of the little-known species Sowerby's beaked whale. The team's first results show that these dolphins have a surprisingly different, much faster lifestyle than related species. |
| The genetic origins of the world's first farmers clarified Posted: 12 May 2022 09:18 AM PDT The genetic origins of the first agriculturalists in the Neolithic period long seemed to lie in the Near East. A new study shows that the first farmers actually represented a mixture of Ice Age hunter-gatherer groups, spread from the Near East all the way to south-eastern Europe. |
| Effectively removing emerging contaminants in wastewater treatment plants Posted: 12 May 2022 06:27 AM PDT Water treatment and environmental decontamination experts have reviewed current and emerging water treatment technologies. Through this review, the team determined the removal efficiency of a particular type of contaminant that causes hormonal disruption: endocrine disruptors. |
| New research could provide earlier warning of tsunamis Posted: 12 May 2022 06:26 AM PDT A new method of detecting mega earthquakes, which picks up on the gravity waves they generate by using deep-learning models, can estimate earthquake magnitude in real time and provide earlier warning of tsunamis. |
| Climate change increases risks of tree death Posted: 12 May 2022 06:26 AM PDT All of that carbon in trees and forests worldwide could be thrown back into the atmosphere if the trees burn up in a forest fire. Trees also stop scrubbing carbon dioxide from the air if they die due to drought or insect damage. The likelihood of those threats impacting forests is increasing nationwide, making relying on forests to soak up carbon emissions a much riskier prospect. |
| How does forest restoration affect water cycles? Posted: 11 May 2022 09:35 AM PDT How would afforestation and restoration of large areas worldwide affect water-fluxes world wide? A new study has interesting answers. Impacts on precipitation reach far beyond country or even continent level: tree restoration in the Amazon can, for example, affect rainfall in Europe and Eastern Asia. The study has calculated the global impact of large-scale tree restoration on water fluxes and water availability. |
