| Climate change to bring more intense storms across Europe Posted: 16 Jul 2021 12:07 PM PDT Investigating how climate affects intense rainstorms across Europe, climate experts have shown there will be a significant future increase in the occurrence of slow-moving intense rainstorms. The scientists estimate that these slow-moving storms may be 14 times more frequent across land by the end of the century. It is these slow-moving storms that have the potential for very high precipitation accumulations, with devastating impacts, as we saw in Germany and Belgium. |
| Role of deep-sea microbial predators at hydrothermal vents examined Posted: 16 Jul 2021 10:15 AM PDT The hydrothermal vent fluids from the Gorda Ridge spreading center in the northeast Pacific Ocean create a biological hub of activity in the deep sea. There, in the dark ocean, a unique food web thrives not on photosynthesis but rather on chemical energy from the venting fluids. Among the creatures having a field day feasting at the Gorda Ridge vents is a diverse assortment of microbial eukaryotes, or protists, that graze on chemosynthetic bacteria and archaea. |
| US corn and soybean maladapted to climate variations Posted: 16 Jul 2021 08:25 AM PDT U.S. corn and soybean varieties have become increasingly heat and drought resistant as agricultural production adapts to a changing climate. But the focus on developing crops for extreme conditions has negatively affected performance under normal weather patterns, a new study shows. |
| First 3D simulation of rat's complete whisker system acts as a tactile 'camera' Posted: 16 Jul 2021 08:25 AM PDT Engineers have developed the first full, three-dimensional (3D), dynamic simulation of a rat's complete whisker system, offering rare, realistic insight into how rats obtain tactile information. |
| Posted: 16 Jul 2021 08:24 AM PDT While tropical forests remain threatened and their future is uncertain, the importance of understanding how well individual protected areas avoid deforestation increases. |
| Private-public partnership helps to evaluate satellite observations of atmospheric CO2 over oceans Posted: 16 Jul 2021 06:10 AM PDT Satellite observations of XCO2 show greater biases apparently over oceans than over the land surface. However, no effective ways to evaluate space-time XCO2 variations over wide geographical areas exist. Observations on commercial ship tracks and aircraft routes, together with atmospehric model calculations, provide a new reference XCO2 dataset for the otherwise inaccesible areas of the world. High quality satellite observations are a requirement for better understanding of the carbon cycle in response to climate change. |
| Nearly 20 percent of intact forest landscapes overlap with extractive industries Posted: 16 Jul 2021 06:10 AM PDT A new study reveals that nearly 20 percent of tropical Intact Forest Landscapes (IFLs) overlap with concessions for extractive industries such as mining, oil and gas. |
| 3D printed replicas reveal swimming capabilities of ancient cephalopods Posted: 16 Jul 2021 06:10 AM PDT Researchers took 3-D printed reconstructions of fossil cephalopods to actual water tanks (including a swimming pool) to see how their shell structure may have been tied to their movement and lifestyle. |
| Climate regulation changed with the proliferation of marine animals and terrestrial plants Posted: 15 Jul 2021 12:38 PM PDT Earth's climate was relatively stable for a long period of time. For three billion years, temperatures were mostly warm and carbon dioxide levels high - until a shift occurred about 400 million years ago. A new study suggests that the change at this time was accompanied by a fundamental alteration to the carbon-silicon cycle. |
| New tool to help farmers make crop input decisions Posted: 15 Jul 2021 12:38 PM PDT A new tool allows farmers to create a budget balance sheet of any nitrogen reduction plans and see the economic and environmental cost, return and margins, all customized to fields under their management. |
| Researchers discover a new inorganic material with lowest thermal conductivity ever reported Posted: 15 Jul 2021 11:23 AM PDT A collaborative research team has discovered a new inorganic material with the lowest thermal conductivity ever reported. This discovery paves the way for the development of new thermoelectric materials that will be critical for a sustainable society. |
| Extraordinary carbon emissions from El Nino-induced biomass burning estimated Posted: 15 Jul 2021 11:23 AM PDT In 2015, massive biomass burning events occurred in Equatorial Asia which released a large amount of carbon into the atmosphere, whose signals were captured by in-situ high-precision measurements onboard commercial passenger aircraft and a cargo ship. A simulation-based analysis with those observations estimated the fire-induced carbon emissions to be 273 Tg C for September - October 2015. |
| Removing the lead hazard from perovskite solar cells Posted: 15 Jul 2021 06:08 AM PDT Although a very promising solution for capturing solar energy, perovskite solar cells contain lead, which is toxic to the environment and a serious health hazard. Scientists have now found a very elegant and efficient solution by adding a transparent phosphate salt that doesn't interfere with light-conversion efficiency while preventing lead from seeping into the soil in cases of solar panel failure. |
| Floating into summer with more buoyant, liquid-proof life jackets, swimsuits Posted: 14 Jul 2021 10:19 AM PDT Summertime is here, and that often means long, lazy days at the beach, water skiing and swimming. Life jackets and swimsuits are essential gear for these activities, but if not dried thoroughly, they can develop a gross, musty smell. Now, researchers have developed a one-step method to create a buoyant cotton fabric for these applications that is also oil- and water-repellent. |
| Study shows forests play greater role in depositing toxic mercury across the globe Posted: 12 Jul 2021 03:33 PM PDT Environmental scientists say mercury measurements in a Massachusetts forest indicate the toxic element is deposited in forests across the globe in much greater quantities than previously understood. |
| Symbionts without borders: Bacterial partners travel the world Posted: 12 Jul 2021 12:03 PM PDT Some microscopic bacteria in the ocean partner up with clams from the family Lucinidae, which live unseen in the sand beneath the shimmering blue waters of coastal habitats. This partnership is the clams' passport to their extensive global reach. The bacteria can also travel a long way. Scientists now show that the bacterial symbionts living in lucinid gills can travel the world without borders. |
