| How to assess a community's resilience Posted: 25 Apr 2022 11:42 AM PDT Communities large and small exist throughout the West where water is life. Social systems are entwined with water systems, so water supply challenges are social challenges. To understand how the connection between those systems impacts communities' water supply resilience, researchers have developed a new framework to think about social water resilience. |
| Being in nature: Good for mind, body and nutrition Posted: 25 Apr 2022 10:59 AM PDT Researchers have investigated how nature relatedness -- simply feeling connected with the natural world -- benefits dietary diversity and fruit and vegetable intake. |
| Meat consumption must fall by at least 75 percent Posted: 25 Apr 2022 10:59 AM PDT If our planet Earth is to continue feeding us in the future, rich countries must significantly reduce their meat consumption -- ideally by at least 75 percent. The study reviews the current state of research on various aspects of meat consumption. In addition to the effects on the environment and climate, these include health and economic effects. |
| These male spiders catapult at impressive speeds to flee their mates before they get eaten Posted: 25 Apr 2022 09:11 AM PDT After males of the orb-weaving spider Philoponella prominens mate with a female, they quickly launch themselves away, researchers report. Using a mechanism that hadn't been described before, the male spiders use a joint in their first pair of legs to immediately undertake a split-second catapult action, flinging themselves away from their partners at impressive speeds clocked at up to 88 centimeters per second (cm/s). |
| Cheaper hydrogen fuel cell could mean better green energy options Posted: 25 Apr 2022 09:11 AM PDT Researchers have developed a hydrogen fuel cell that uses iron instead of rare and costly platinum, enabling greater use of the technology. |
| Researchers discover drug-resistant environmental mold is capable of infecting people Posted: 25 Apr 2022 09:10 AM PDT A new study finds that drug-resistant mold is spreading from the environment and infecting susceptible people's lungs. |
| Posted: 25 Apr 2022 09:10 AM PDT A major new study shows adding rock dust to UK agricultural soils could remove between 6 and 30 million tons of carbon dioxide (CO2) from the atmosphere annually by 2050. |
| Study identifies gaps in monitoring of streams Posted: 25 Apr 2022 09:10 AM PDT 'We find that gauges are located disproportionally in large, perennial rivers draining more human-occupied watersheds,' the authors write in their paper, which will be published on April 25 in Nature Sustainability. 'Gauges are sparsely distributed in protected areas and rivers characterized by non-perennial flow regimes, both of which are critical to freshwater conservation and water security concerns.' |
| Bean cultivation in diverse agricultural landscapes promotes bees and increases yields Posted: 25 Apr 2022 07:49 AM PDT Pollination by insects is essential for the production of many food crops. The presence of pollinators, such as bees, depends on the availability of nesting sites and sufficient food. If these conditions are lacking, the pollinators also fail to appear and the yield of flowering arable crops, such as broad beans or oilseed rape, suffers as well. A team has investigated how the composition of flowering crops and semi-natural habitats in the landscape affects the density of bees, their behavior when collecting nectar, and the faba bean (Vicia faba) yields. |
| When male bees don't get lucky Posted: 25 Apr 2022 07:49 AM PDT Do pesticides have anything to do with the decline in bee populations? A research team has now found a connection between fenbuconazole and the insects' mating behavior. |
| Automated analysis of animal behavior Posted: 25 Apr 2022 07:48 AM PDT Researchershave developed a new method that uses artificial intelligence to analyze animal behavior. This opens the door to longer-term in-depth studies in the field of behavioral science -- while also helping to improve animal welfare. |
| Ecotourism is having a negative effect on primate's behavior Posted: 25 Apr 2022 07:48 AM PDT New research shows that the increase in primate ecotourism is having a negative effect on monkey's behavior. The study found that this fast-growing tourism sector where tourists can conveniently reach primates via motor boats is causing stress-related behaviors in monkeys. |
| Marine mollusc shells reveal how prehistoric humans adapted to intense climate change Posted: 25 Apr 2022 05:57 AM PDT A study reveals the impact and consequences of the '8.2 ka event', the largest abrupt climate change of the Holocene, for prehistoric foragers and marine ecology in Atlantic Europe. |
| Meet the forest microbes that can survive megafires Posted: 25 Apr 2022 05:57 AM PDT New research shows fungi and bacteria able to survive redwood tanoak forest megafires are microbial 'cousins' that often increase in abundance after feeling the flames. |
| Volcanoes at fault if the Earth slips Posted: 22 Apr 2022 06:43 AM PDT A new study has attributed the root cause of the 2016 Kumamoto earthquakes to specific geological damage. A relatively large dip-slip displacement was discovered at the site. The Futagawa strike-slip fault is a vertical break in the ground tracing a line southwest originating from Mount Aso. |
