| Paris Climate Agreement goal still within reach, suggests new study Posted: 11 Feb 2022 01:13 PM PST A new study suggests some cautiously optimistic good news: The 2015 Paris Climate Agreement goal is still within reach, while apocalyptic, worst-case scenarios are no longer plausible. |
| First evidence indicating dinosaur respiratory infection Posted: 11 Feb 2022 07:27 AM PST Scientists have discovered the first evidence of a unique respiratory infection in the fossilized remains of a dinosaur that lived nearly 150 million years ago. Researchers examined the remains of an immature diplodocid -- a long-necked herbivorous sauropod dinosaur, like 'Brontosaurus' - dating back to the Late Jurassic Period of the Mesozoic Era. The dinosaur nicknamed 'Dolly,' discovered in southwest Montana, had evidence of an infection in the area of its neck vertebrae. |
| Writing is not present in all 'complex' societies, but it can signal inequality Posted: 11 Feb 2022 07:27 AM PST For a long time, anthropologists believed that a written language was a hallmark of a society being complex or 'advanced.' A new study on precolonial Mesoamerican societies shows that you can have a society with a big population and a complex government without a writing system. However, societies with writing systems tended to be less egalitarian than ones without. |
| How El Niño and drought affected the Trans-Atlantic Slave Trade Posted: 11 Feb 2022 07:25 AM PST The oceanic phenomenon El Niño significantly affected the number of enslaved Africans transported from West Africa to the Americas between the mid-1600s and mid-1800s, according to a new study. The study bridges atmospheric science with African history, carrying lessons for a warming future. It found that, much like tree rings and corals, El Niño can be used as a proxy for historical rainfall and temperature patterns in West Africa. |
| Portable toilets of the ancient Roman world Posted: 11 Feb 2022 05:06 AM PST Archaeologists develop method of identifying intestinal parasites concealed within 1,500-year-old 'chamber pot'. New technique helps distinguish portable toilets from other jars and ceramic vessels, leading to greater understanding of gut health in the past. |
| Mystery origin of iconic Aussie snakes unlocked Posted: 10 Feb 2022 12:41 PM PST New research has found the first tangible evidence that the ancestors of some of Australia's most venomous snakes arrived by sea rather than by land -- the dispersal route of most other Australian reptiles. |
| Notches on lions’ teeth reveal poaching in Zambia’s conservation areas Posted: 10 Feb 2022 09:58 AM PST New research links notches on lion teeth with snare traps, revealing significantly more poaching in conservation areas than previously estimated. Researchers used photos of trophy-hunted lions and leopards -- especially of their teeth -- to do forensic work evaluating the effectiveness of conservation efforts in Zambia. |
| Black Death mortality not as widespread as long thought Posted: 10 Feb 2022 08:40 AM PST A new study used pollen data to evaluate the second plague pandemic's mortality at a regional scale across Europe. Results showed that the impacts of the Black Death varied substantially from region to region and demonstrated the importance of cross-disciplinary approaches for understanding past -- and present -- pandemics. |
