| Did Earth's early rise in oxygen help multicellular life evolve? Posted: 18 May 2021 05:54 PM PDT Researchers find that oxygenation of Earth's surface is key to the evolution of large, complex multicellular organisms. If cells can access oxygen, they get a big metabolic benefit. However, when oxygen is scarce, it can't diffuse very far into organisms, so there is an evolutionary incentive for multicellular organisms to be small to ensure most of their cells can still access oxygen. |
| Discovery increases likelihood of growing food despite drought Posted: 18 May 2021 08:48 AM PDT Scientists have discovered genetic data that will help food crops like tomatoes and rice survive longer, more intense periods of drought on our warming planet. |
| Alien radioactive element prompts creation rethink Posted: 18 May 2021 08:42 AM PDT The first-ever discovery of an extraterrestrial radioactive isotope on Earth has scientists rethinking the origins of the elements on our planet. |
| Colonization of the Antilles by South American fauna: Giant sunken islands as a passageway Posted: 18 May 2021 08:42 AM PDT Fossils of land animals from South America have been found in the Antilles, but how did these animals get there? According to scientists from the CNRS, l'Université des Antilles, l'Université de Montpellier and d'Université Côte d'Azur, land emerged in this region and then disappeared beneath the waves for millions of years, explaining how some species were able to migrate to the Antilles. This study will be published in June 2021 issue in Earth-Science Reviews. |
| Novel methods to improve the range and safety of e-vehicles Posted: 18 May 2021 08:41 AM PDT A recent project has revealed innovative methods that could dramatically improve the performance of future electrical vehicles (e-vehicles). |
| New species formed when the Mediterranean dried up Posted: 18 May 2021 08:41 AM PDT A new study may have uncovered why wall lizards have become the most successful reptile in the Mediterranean region. The results reveal how drastic changes in sea levels and climate 6 million years ago affected species formation in the area. The researchers believe they can now explain why the lizards became so diverse and widespread, something that has puzzled biologists since the 19th century. |
| African rainforests still slowed climate change despite record heat and drought Posted: 17 May 2021 04:47 PM PDT Intact rainforests across tropical Africa continued to remove carbon from the atmosphere before and during the 2015-2016 El Niño, despite the extreme heat and drought. Theyl removed 1.1 billion tons of carbon dioxide per year from the atmosphere during the El Niño monitoring period. This rate is equivalent to three times the carbon dioxide emissions of the UK in 2019. Scientists were surprised by this discovery. |
| Newly published data provides clearer picture of volcano collapse Posted: 17 May 2021 11:47 AM PDT A recent article reveals new data on the Anak Krakatau volcano flank collapse, which was triggered by an eruption on Detcember 22, 2018. |
| Mammals in the time of dinosaurs held each other back Posted: 17 May 2021 09:49 AM PDT Scientists discover that dinosaurs were not the main competition for mammals during the time of the dinosaurs, challenging previously held ideas about evolution. |
