| Making musical performances safer in the era of COVID-19 Posted: 15 Sep 2021 10:51 AM PDT Researchers have studied aerosol production from playing wind instruments, singing and acting, allowing them to develop recommendations to minimize COVID transmission. |
| Milk enabled massive steppe migration Posted: 15 Sep 2021 08:10 AM PDT The long-distance migrations of early Bronze Age pastoralists in the Eurasian steppe have captured widespread interest. But the factors behind their remarkable spread have been heavily debated by archaeologists. Now a new study provides clues regarding a critical component of the herders' lifestyle that was likely instrumental to their success: dairying. |
| ‘Whoop’ – new autonomous method precisely detects endangered whale vocalizations Posted: 15 Sep 2021 06:54 AM PDT One of the frequently used methods to monitor endangered whales is called passive acoustics technology, which doesn't always perform well. In the increasingly noisy ocean, current methods can mistake other sounds for whale calls. This high 'false positive' rate hampers scientific research and hinders conservation efforts. Researchers used artificial intelligence and machine learning methods to develop a new and much more accurate method of detecting Right whale up-calls -- a short 'whoop' sound that lasts about two seconds. |
| Roads have far-reaching impact on chimpanzees Posted: 15 Sep 2021 05:58 AM PDT Roads have a negative impact on chimpanzee populations that can extend for more than 17 km, new research shows. |
| Natural cycles in the Gulf of Alaska accentuate ocean acidification Posted: 15 Sep 2021 05:58 AM PDT New research shows that the fluctuations of major wind and ocean circulation systems can temporarily accelerate or reverse the rate of ocean acidification in the Gulf of Alaska. |
| Concentration of microparticles in lakes reflect nearby human activity and land use Posted: 14 Sep 2021 12:25 PM PDT A new study suggests that microparticle concentrations in lakes are higher than previously reported, and that human activity and surrounding land use may be a strong predictor of microplastics and anthropogenic fiber pollution. |
| Rapid increase in global light pollution Posted: 14 Sep 2021 08:13 AM PDT Global light pollution has increased by at least 49% over 25 years, new research shows. |
| Solar cells with 30-year lifetimes for power-generating windows Posted: 14 Sep 2021 08:12 AM PDT A new transparency-friendly solar cell design could marry high efficiencies with 30-year estimated lifetimes, new research has shown. It may pave the way for windows that also provide solar power. |
| Modern snakes evolved from a few survivors of dino-killing asteroid Posted: 14 Sep 2021 08:12 AM PDT A new study suggests that all living snakes evolved from a handful of species that survived the giant asteroid impact that wiped out the dinosaurs and most other living things at the end of the Cretaceous. The authors say that this devastating extinction event was a form of 'creative destruction' that allowed snakes to diversify into new niches, previously filled by their competitors. |
| Species in polar regions hard hit by climate change Posted: 14 Sep 2021 08:02 AM PDT Many species will become extinct as a consequence of global warming. This is the prediction of a mathematical model. The simulations show that climate change will have a particularly large impact on ecosystems in polar regions, mirroring changes that can already be seen in the natural world. |
| Jet stream changes could amplify weather extremes by 2060s Posted: 13 Sep 2021 07:02 PM PDT The ribbon of fast winds familiar to air travelers between North America and Europe is a big influencer on weather in North America and Europe. By drilling deep into the Greenland Ice Sheet, researchers reconstructed the jet stream's past and found that climate-caused disruptions are likely to have drastic weather-related consequences for societies on both sides of the Atlantic. |
| Thousands of tiny anchors keep our cells in place – and now we know how Posted: 13 Sep 2021 10:58 AM PDT Most of our cells are locked into place with the help of tiny anchors (called 'focal adhesions'). But if a cell morphs into a cancer cell, the chain can break, letting the cancer spread to other parts of the body. A team of scientists have now found the specific protein (or link) in the chain responsible for upholding the connection. The discovery gives scientists new directions for future cancer research. |
| Utilitarian approach to global climate policy improves equity, environment and wellbeing Posted: 13 Sep 2021 10:57 AM PDT An approach to reducing greenhouse gas emissions that is informed by the ethical theory of utilitarianism would lead to better outcomes for human development, equity, and the climate, according to a new study. |
| Uncertainty on climate change in textbooks linked to uncertainty in students Posted: 13 Sep 2021 10:56 AM PDT A new study suggests textbook wording that portrays climate change information as uncertain can influence how middle and high school students feel about the information, even for students who say they already know about climate change and its human causes. |
| Critical data needed for monitoring and preserving biodiversity is missing Posted: 09 Sep 2021 09:42 AM PDT The world's largest repository of raw genomic sequences from wild plants, animals and fungi is missing critical data necessary to monitor and protect the Earth's biological diversity, according to a new study. The missing data includes the time and location the organism's sample was collected, which is needed for monitoring the genetic diversity of populations. |
| Tropical crops could suffer as climate change brings longer dry spells Posted: 07 Sep 2021 01:06 PM PDT Study looked at expected changes to rainfall and length of dry spells during dry and wet seasons in tropics separately, since the impacts of changes to rainfall patterns depends on timing. The researchers found dry spells would be up to 10 days longer, there would be less rainfall, and average temperatures would rise by up to 3C in several regions during the dry season. The onset of the wet season was also found to shift up to two weeks later in many regions. |
