| Using engineering methods to track the imperceptible movements of stony corals Posted: 20 Apr 2021 03:31 PM PDT A new study borrowed image-analysis methods from engineering to spot the minute movements of a stony coral. |
| Was Cascadia's 1700 earthquake part of a sequence of earthquakes? Posted: 20 Apr 2021 01:09 PM PDT The famous 1700 Cascadia earthquake that altered the coastline of western North America and sent a tsunami across the Pacific Ocean to Japan may have been one of a sequence of earthquakes, according to new research. |
| Restoration efforts can brighten an ecosystem's future, but cannot erase its past Posted: 20 Apr 2021 01:09 PM PDT An expansive project is examining the benefits, and limits, of environmental restoration on developed land after humans are done with it. |
| Deregulated US Government oversight on interstate waters leaves murky implications for states Posted: 20 Apr 2021 01:09 PM PDT Concern tends to ratchet up a notch when pollution enters the river runoff discussion on a national scale, specifically when smaller, navigable intrastate bodies of water push pollution into larger interstate waters often involved in commerce (i.e. the Mississippi River, Great Lakes, Ohio River). |
| 'Dead clades walking': Fossil record provides new insights into mass extinctions Posted: 20 Apr 2021 01:09 PM PDT Mass extinctions are known as times of global upheaval, causing rapid losses in biodiversity that wipe out entire animal groups. Some of the doomed groups linger on before going extinct, and a team of scientists found these 'dead clades walking' (DCW) are more common and long-lasting than expected. |
| Fixed network of smartphones provides earthquake early warning in Costa Rica Posted: 20 Apr 2021 10:10 AM PDT Earthquake early warnings can be delivered successfully using a small network of off-the-shelf smartphones attached to building baseboards, according to a study conducted in Costa Rica last year. |
| Review summarizes known links between endocrine disruptors and breast cancer risk Posted: 20 Apr 2021 09:15 AM PDT Exposure to certain endocrine-disrupting chemicals could elevate the risk of breast cancer, according to a new comprehensive systematic review of epidemiological research. However, for many chemicals, evidence is inconsistent or still limited. |
| New catalyst for lower CO2 emissions Posted: 20 Apr 2021 09:15 AM PDT Perovskites have so far been used for solar cells, as anode materials or electronic components rather than for their catalytic properties. Now scientists have succeeded in producing a special perovskite that is excellently suited as a catalyst for converting CO2 into other useful substances, such as synthetic fuels. The new perovskite catalyst is very stable and also relatively cheap, so it would be suitable for industrial use. |
| Oceanographers reveal links between migrating Gulf Stream and warming ocean waters Posted: 20 Apr 2021 09:14 AM PDT The Northwest Atlantic Shelf is one of the fastest-changing regions in the global ocean, and is currently experiencing marine heat waves, altered fisheries and a surge in sea level rise along the North American east coast. A new article reveals the causes, potential predictability and historical context for these types of rapid changes. |
| Cool and COVID-safe: How radiant cooling could keep our cities comfortable and healthy Posted: 20 Apr 2021 06:29 AM PDT A novel system of chilled panels that can replace air conditioning can also help reduce the risk of indoor disease transmission, new analysis suggests. |
| Can extreme melt destabilize ice sheets? Posted: 20 Apr 2021 06:28 AM PDT Researchers have deciphered a trove of data that shows one season of extreme melt can reduce the Greenland Ice Sheet's capacity to store future meltwater - and increase the likelihood of future melt raising sea levels. |
| Rock glaciers will slow Himalayan ice melt Posted: 20 Apr 2021 06:28 AM PDT Some Himalayan glaciers are more resilient to global warming than previously predicted, new research suggests. |
| People have shaped Earth's ecology for at least 12,000 years, mostly sustainably Posted: 19 Apr 2021 03:21 PM PDT New research shows that land use by human societies has reshaped ecology across most of Earth's land for at least 12,000 years. Researchers, from over a dozen institutions around the world, assessed biodiversity in relation to global land use history, revealing that the appropriation, colonization, and intensified use of lands previously managed sustainably is the main cause of the current biodiversity crisis. |
| GPS data reveal possible earthquake, tsunami hazard in Northwestern Colombia Posted: 19 Apr 2021 10:56 AM PDT Data from a GPS network in Colombia have revealed a shallow and fully locked part on the Caribbean subduction zone in the country that suggests a possible large earthquake and tsunami risk for the northwest region. |
| Can magnitude 4 earthquake rates be used to forecast large earthquake events? Posted: 19 Apr 2021 10:56 AM PDT Ebel looked for the California faults that had magnitude 4 or larger earthquakes occurring at a rate higher than 0.5 earthquakes per year from 1997 to 2016. If the pattern holds, the next magnitude 6.7 earthquakes in California are most likely to occur along these faults. |
