Templating approach stabilizes 'ideal' material for alternative solar cells Posted: 23 Dec 2021 11:31 AM PST Researchers have developed a method to stabilize a promising material known as perovskite for cheap solar cells, without compromising its near-perfect performance. |
Posted: 23 Dec 2021 11:30 AM PST The two-meter skull of an enormous new ichthyosaur species, Earth's first known giant creature, reveals how both the extinct marine reptiles and modern whales became giants. |
Geneticists’ new research on ancient Britain contains insights on language, ancestry, kinship, milk Posted: 22 Dec 2021 12:31 PM PST New research revealing a major migration to the island of Great Britain offers fresh insights into the languages spoken at the time, the ancestry of present-day England and Wales, and even ancient habits of dairy consumption. |
Solar flare throws light on ancient trade between the Islamic Middle East and the Viking Age Posted: 22 Dec 2021 12:30 PM PST An interdisciplinary Danish team of researchers has used new astronomical knowledge to establish an exact time anchor for the arrival of trade flows from the Middle East in Viking-age Scandinavia. The results are published in the leading international journal Nature. |
Study finds electric vehicles provide lower carbon emissions through additional channels Posted: 21 Dec 2021 06:25 PM PST A recent study found that the total indirect emissions from the supply of chain of electric vehicles pale in comparison to the same indirect emissions from fossil fuel-powered vehicles. |
Your seat on public transportation determines level of exposure to exhaled droplets, study finds Posted: 21 Dec 2021 10:35 AM PST In a new study, researchers developed a model with an unprecedented level of detail and focused on conditions that are more characteristic of asymptomatic transmission. The multiphysics model involved air and droplet dynamics, heat transfer, evaporation, humidity, and effects of ventilation systems. The researchers modeled various scenarios in close detail and were able to reconstruct their ventilation paths. |
Posted: 21 Dec 2021 10:34 AM PST As the Arctic and the oceans warm due to climate change, understanding how a rapidly changing environment may affect birds making annual journeys between the Arctic and the high seas is vital to international conservation efforts. However, for some Arctic species, there are still many unknowns about their migration routes. Using telemetry to solve some mysteries of three related seabird species -- the pomarine jaeger, parasitic jaeger and long-tailed jaeger -- scientists discovered they took different paths across four oceans from a shared central Canadian high Arctic nesting location. |
