| Unravelling the mystery of parrot longevity Posted: 29 Mar 2022 12:28 PM PDT Bigger brains have led some species of parrot to live surprisingly long lives, new research shows. |
| Zebra finch males sing in dialects and females pay attention Posted: 29 Mar 2022 12:28 PM PDT Male zebra finches learn their song by imitating conspecifics. To stand out in the crowd, each male develops its own unique song. Because of this individual-specific song, it was long assumed that dialects do not exist in zebra finches. However, with the help of an artificial intelligence technique, researchers have now been able to show that the songs of four different zebra finch populations differ systematically. They also discovered that these 'cryptic dialects' are decisive for the females' choice of mate. Thus, female zebra finches pay more attention to a cultural trait than to male appearance. |
| Roundworms’ egg cells have a backup plan Posted: 29 Mar 2022 11:25 AM PDT Researchers discovered a previously unknown mechanism in roundworms that protects their egg cells from division errors. Uncovering and understanding this hidden mechanism could ultimately lead to new strategies for combating infertility in humans. |
| Posted: 29 Mar 2022 11:25 AM PDT Researchers presented the results of efforts to perform global full waveform inversions of the Earth using the Frontera supercomputer. They used data from 300 earthquakes to construct the new global full wave inversion models that include attenuation and azimuthal anisotropy and approach continental-scale resolution. The researchers also recently released a visualization toolbox for large seismic model files and are building a platform for seismic analysis. |
| New software to help discover valuable compounds Posted: 29 Mar 2022 11:25 AM PDT Because the comparative metabolomics field lacks sophisticated data analysis tools that are available to genomics and proteomics researchers, metabolomics researchers spend a lot of time hunting for candidate compounds that could be useful as leads for the development of new pharmaceuticals or agrochemicals. To solve this problem, scientists have developed Metaboseek, a free, easy-to-use app that integrates multiple data analysis features for the metabolomics community. |
| Describing the devastating eruption in Tonga Posted: 29 Mar 2022 11:25 AM PDT On January 15, the volcano Hunga Tonga-Hunga Ha'apai devastated the nation of Tonga. The eruption triggered tsunamis as far afield as the Caribbean and generated atmospheric waves that travelled around the globe several times. Meanwhile, the volcano's plume shot gas and ash through the stratosphere into the lower mesosphere. |
| Plastic bag bans may unintentionally drive other bag sales Posted: 29 Mar 2022 11:23 AM PDT When cities or counties institute plastic bag bans or fees, the idea is to reduce the amount of plastic headed to the landfill. But a new analysis finds these policies, while created with good intentions, may cause more plastic bags to be purchased in the communities where they are in place. |
| Sensor for faster, more accurate COVID-19 tests Posted: 29 Mar 2022 08:47 AM PDT Researchers say the sensor combines accuracy levels approaching that of PCR testing with the speed of rapid antigen tests, and could be used for mass testing at airports, schools, and hospitals. |
| Nature-based carbon removal can help protect us from a warming planet Posted: 29 Mar 2022 08:47 AM PDT A new study finds that temporary nature-based carbon removal can lower global peak warming levels but only if complemented by ambitious fossil fuel emission reductions. |
| Scientists achieve record efficiency for ultra-thin solar panels Posted: 29 Mar 2022 08:47 AM PDT A team has successfully increased the levels of energy absorbed by wafer-thin photovoltaic panels by 25%. Their solar panels, just one micrometer thick, convert light into electricity more efficiently than others as thin and pave the way to make it easier to general more clean, green energy. |
| Posted: 29 Mar 2022 08:47 AM PDT According to the latest assessment report from the Intergovernmental Panel on Climate Change, a considerable reduction in CO2 emissions is required to limit the consequences of climate change. Producing fuel from renewable sources such as waste wood and straw or renewable electricity would be one way to reduce carbon emissions from the area of transportation. |
| Dried avocado meal, a novel fiber source to be added to commercial dog food Posted: 29 Mar 2022 08:47 AM PDT Thanks to avocados' rise to superfood stardom, there are now more avocado-derived products in the supply chain than ever. In a unique study, researchers looked at the possibility of using avocado meal -- the ground, dried, and defatted pulp, seed, and skin left over after avocado oil processing -- as a fiber source in dry dog food. |
| Heat storage: Scientists develop material that is stable, efficient and eco-friendly Posted: 29 Mar 2022 07:00 AM PDT A new heat storage material could help to significantly improve the energy efficiency of buildings. It can be used to store surplus heat and release it back into the environment when needed. Unlike existing materials, the new one can absorb significantly more heat, is more stable, and is made of harmless substances. |
