| Astrophysics student discovers link between global warming and locally unstable weather Posted: 25 May 2022 07:29 AM PDT Climate change gives rise to more unstable weather, local droughts and extreme temperature records, but a coherent theory relating local and global climate is still under active development. Now an astrophysics student has used a mathematical approach -- inspired by research in the Universe's light -- to unveil how global temperature increase engenders locally unstable weather on Earth. |
| Some nomadic birds look for social cues to stop migrating Posted: 25 May 2022 05:05 AM PDT A study of nomadic pine siskins, a type of finch often seen on backyard feeders, found that when male migratory siskins were paired with a settled male bird in captivity, they started exhibiting signs of ending migration too. They stopped restless flying and lost body mass, fat stores and muscle size, compared to a control group placed in solo enclosures. The apparent reliance on social cues for the end of migration has implications for other nomadic animals as well. |
| The road to success when it comes to mitigating flood disasters Posted: 25 May 2022 05:04 AM PDT As Australia continues to mop up after one of the wettest years on record, councils might want to consider a new flood mitigation strategy -- permeable pavements to suit specific soil and rainfall conditions. |
| Highest Efficiency 1-Sun Solar Cell Posted: 24 May 2022 02:12 PM PDT Researchers have created a solar cell with a record 39.5% efficiency under 1-sun global illumination. This is believed to be the highest efficiency solar cell of any type, measured using standard 1-sun conditions. |
| Experts forecast the wind plant of the future to be taller and more economical Posted: 24 May 2022 01:36 PM PDT Anticipating key features of wind plants a decade or more ahead of their installation can inform today's investment, research, and energy system planning decisions. Researchers elicited opinions from more than 140 of the world's leading experts about their expectations of future wind plant design in 2035. |
| Scientists develop method for seasonal prediction of Western wildfires Posted: 24 May 2022 09:49 AM PDT This summer's Western wildfire season is likely to be more severe than average but not as devastating as last year's near-record, according to an experimental prediction method that predicts wildfire season months in advance. |
| Posted: 24 May 2022 09:48 AM PDT How stress is transmitted from one animal to another is the study topic of behavioral ecologists and collective behavior researchers. |
| Climate change on course to hit U.S. Corn Belt especially hard, study finds Posted: 24 May 2022 09:46 AM PDT Climate change will make the U.S. Corn Belt unsuitable for cultivating corn by 2100 without major technological advances in agricultural practices, a new study finds. |
| Secret to treating 'Achilles' heel' of alternatives to silicon solar panels revealed Posted: 24 May 2022 08:07 AM PDT A team of researchers has found that the tiny defects which limit the efficiency of perovskites -- cheaper alternative materials for solar cells -- are also responsible for structural changes in the material that lead to degradation. |
| Scientists make plastic more degradable under UV light Posted: 24 May 2022 08:06 AM PDT Scientists found that incorporating sugar units into polymers makes them more degradable when exposed to UV light. |
| Curbing other climate pollutants, not just CO2, gives Earth a chance Posted: 24 May 2022 08:06 AM PDT Slashing emissions of carbon dioxide by itself isn't enough to prevent catastrophic global warming, a new study shows. But if we simultaneously also reduce emissions of methane and other often overlooked climate pollutants, we could cut the rate of global warming in half by 2050 and give the world a fighting chance. |
| Human influence is the culprit for warm and wet winters in northwest Russia Posted: 24 May 2022 07:05 AM PDT A research team reveals the reason behind hot and wet winters in northwest Russia from 2019/20 winter. Anthropogenic influence found to be the reason for widespread warming according to the CMIP6 data. |
| Posted: 24 May 2022 07:05 AM PDT Mustelids are the most ecologically and taxonomically diverse family within the order Carnivora. From the tayra in the neotropics to the wolverine in the subarctic, they inhabit a variety of ecological niches and developed corresponding species-specific traits related to their diet, reproductive strategy and morphology. An international team of scientists conducted a comparative analysis of whole genomes of several mustelids to obtain insights into the molecular basis of these adaptations. |
