| Posted: 04 Apr 2022 12:01 PM PDT As the demand for home deliveries from online purchases continues to increase, researchers recently published research showing that some -- but not all -- consumers will accept going to alternate delivery locations to get their packages rather than having them delivered directly to their front door. |
| Solar hydrogen: Better photoelectrodes through flash heating Posted: 04 Apr 2022 09:05 AM PDT Producing low-cost metal-oxide thin films with high electronic quality for solar water splitting is not an easy task. Especially since quality improvements of the upper metal oxide thin films need thermal processing at high temperatures, which would melt the underlying glass substrate. Now, a team has solved this dilemma: A high intensity and rapid light pulse directly heats the semiconducting metal-oxide thin film, allowing it to reach the optimal temperature without damaging the substrate. |
| Urban agriculture in Detroit: Scattering vs. clustering and the prospects for scaling up Posted: 04 Apr 2022 07:57 AM PDT Despite Detroit's reputation as a mecca for urban agriculture, a new analysis of the city's Lower Eastside, which covers 15 square miles, found that community and private gardens occupy less than 1% of the vacant land. |
| Spotted hyenas adjust their foraging behavior in response to climate change Posted: 04 Apr 2022 07:57 AM PDT Spotted hyenas adjust to a decreased presence of migratory prey in their territories induced by climate change. Researchers investigated the relationship between rainfall volume and migratory herbivore presence in hyena clan territories in the Serengeti National Park, Tanzania, and the responses of lactating hyenas to recent changes in the climate-prey relationship. |
| Freshwater mussels can inhibit bacterial diseases Posted: 04 Apr 2022 06:30 AM PDT Researchers have found brown trout better survived a Flavobacterium disease outbreak if the fish had larvae of freshwater pearl mussel in their gills. In another study, duck mussels were observed to filter and remove Flavobacterium from the water. |
| Drenching rains to pose greater threat to fire-damaged areas in West Posted: 01 Apr 2022 11:13 AM PDT The western United States this century is facing a greatly heightened risk of heavy rains inundating areas recently scarred by wildfires, new research warns. Such events can cause significant destruction, including debris flows, mudslides, and flash floods, because the denuded landscape cannot easily contain the drenching moisture. |
| Stormwater harvesting benefits city trees Posted: 31 Mar 2022 07:15 AM PDT Reports of tree canopy coverage dwindling across city suburbs raise pressure on local government and other authorities' efforts to improve the health of urban street trees. New research has found stormwater interception and infiltration that allows water to soak into tree root zones is proving effective for a shady tree canopy in concrete urban environments where extreme heat occurs regularly. |
