| Researchers refine estimate of amount of carbon in Earth’s outer core Posted: 19 Aug 2021 08:30 AM PDT New research is providing a better estimate of the amount of carbon in the Earth's outer core, and the work suggests the core could be the planet's largest reservoir of that element. |
| Study of tyrannosaur braincases shows more variation than previously thought Posted: 19 Aug 2021 07:26 AM PDT Scientists have used CT scans to digitally reconstruct the brain, inner ear, and surrounding bones (known as the braincase) of two well-preserved Daspletosaurus specimens. This massive tyrannosaur lived in the coastal forest of what is now Alberta around 75 million years ago -- preceding the more famous T. rex by about 10 million years. Their results suggest that dinosaur brains, and the bones enclosing and protecting, them vary more than previously thought within species, or among closely related species. |
| Humans managed shellfish and their predators for millennia Posted: 18 Aug 2021 05:02 PM PDT A new study confirms that for millennia, Indigenous people managed their relationship with shellfish and sea otters to safeguard their access to shellfish which remain important for food, social, and ceremonial uses today. |
| Scientists dig deep to understand the effects of population pressure on violence levels Posted: 18 Aug 2021 10:05 AM PDT A continuous rise in global population has led to fears that conflicts and war will become more frequent as resources dwindle. But this widespread belief has not been quantified based on actual Japanese archaeological data, until now. Researchers have now examined the skeletal remains of people living in the Middle Yayoi period of Japan to set the record straight on the relationship between population pressure and the frequency of violence. |
| Treading wander paths to uncover the geological history of southwest Japan Posted: 18 Aug 2021 10:05 AM PDT The breakup of the supercontinent and formation of the current Afro-Eurasia landmass were caused by movement of Earth's tectonic plates. The position of these tectonic plates is preserved in magnetic fields in rocks. These remnant magnetic fields can help generate apparent polar wander paths (APWPs). Researchers have now constructed an APWP of southwest Japan and compared it to that of East Asia, shedding light on the interaction between the Asian continent and southwest Japan. |
| History of the spread of pepper (C. annuum) is an early example of global trade Posted: 16 Aug 2021 01:13 PM PDT (Gatersleben, 17.08.2021) Genetic data stored in genebanks confirm that pepper, thanks to its flexible features (easily preserved and transportable in dried form, needed in moderate quantity to enrich dishes, easy to produce and wide scale) has been spread along with the very earliest intercontinental traders, being among the first examples of a globally-traded, mass-market, consumer-discretionary good. These are the conclusions of a study conducted by an international team in which IPK Leibniz Institute researchers played a central role, the results of which have now been published in the magazine PNAS. |
