| Posted: 11 Nov 2021 06:46 PM PST Volcanic eruptions may have triggered abrupt climate changes contributing to the repeated collapse of Chinese dynasties over the past 2,000 years, according to new research. The study also illustrates how volcanic eruptions can profoundly impact vulnerable or unstable regions and highlights the need to prepare for future eruptions. |
| Fate of sinking tectonic plates is revealed Posted: 11 Nov 2021 10:03 AM PST When tectonic plates sink into the Earth they look like slinky snakes! That's according to a study published in Nature, which helps answer a long standing question about what happens to tectonic plates when they sink - or subduct - into the Earth's interior. The process helps drive plate tectonics. |
| Humans hastened the extinction of the woolly mammoth Posted: 11 Nov 2021 10:03 AM PST New research shows that humans had a significant role in the extinction of woolly mammoths in Eurasia, occurring thousands of years later than previously thought. An international team of scientists has revealed a 20,000-year pathway to extinction for the woolly mammoth. |
| Novel approach to a plant-based diet, unique to long-necked dinosaurs Posted: 11 Nov 2021 05:04 AM PST A new study uncovers a novel approach to a plant-based diet, unique to long-necked dinosaurs. |
| New species of iguanodontian dinosaur discovered from Isle of Wight Posted: 11 Nov 2021 04:54 AM PST Discoveries of iguanodontian dinosaurs from the Isle of Wight have previously only been assigned to Iguanodon or Mantellisaurus . The diversity of dinosaurs in the Early Cretaceous of the UK is much greater than previously thought. |
| Introduced birds are not replacing roles of human-caused extinct species Posted: 10 Nov 2021 11:54 AM PST Human-caused bird extinctions are driving losses of functional diversity on islands worldwide, and the gaps they leave behind are not being filled by introduced (alien) species, finds a new study. |
| Genetic analysis uncovers shared evolutionary history of fish fins and vertebrate limbs Posted: 08 Nov 2021 01:14 PM PST Scientists use CRISPR to show how genes that control growth at the end of fish fins play the same role in fingers and toes. |
| Muscular wing-body junction improved Pterosaur flight performance Posted: 08 Nov 2021 08:48 AM PST The flying reptiles known as pterosaurs are the closest relatives of dinosaurs and were the first vertebrates to evolve powered flight. However, many details of pterosaur flight anatomy and performance are still unclear. According to a new study pterosaurs evolved a muscular wing-body junction to reduce drag and improve flight performance. |
