Earliest evidence of cooking and eating starch – ScienceDaily

New discoveries at Klasie's River Cave in the Cape of South Africa, where charred remains of hearths were found, provide the first archaeological evidence that anatomically modern humans roasted and ate plant levels such as tubers and rhizomes. already 120,000 years ago. Recent research by an international team of archaeologists published in the Journal of Human Evolution provides archaeological evidence …

The ownership of a dog is influenced by our genome – ScienceDaily

A team of Swedish and British scientists has studied the heritability of dog ownership using information from 35,035 twin pairs from the Swedish Twin Registry. The new study suggests that genetic variation accounts for more than half of the variation in dog ownership, implying that the choice of having a dog is strongly influenced by a person's genetic makeup. Dogs …

Almost a quarter of West Antarctic ice is now unstable – ScienceDaily

The British Center for Polar Observation and Modeling (CPOM) has been tracking changes in snow and ice cover across the continent by combining the European Space Agency's 25-year satellite height measurement with a regional climate model. A team of researchers, led by Professor Andy Shepherd of the University of Leeds, found that Antarctic ice has thinned up to 122 meters …

Paper wasps similar to logical thinking – ScienceDaily

A recent study from the University of Michigan provides the first evidence of transitive inference, the ability to use known relationships to close unknown relationships in an animal without a spine: the lower paper wasp. For thousands of years, transitive inference has been a hallmark of human deductive forces, a form of logical reasoning used for inferences: if A is …

Almost all blue supergiants shine in their brightness due to the waves on their surface – ScienceDaily

Blue supergiants are rock-and-roll: they live fast and die young. This makes them rare and difficult to study. Before space telescopes were invented, few blue supergiants were observed, so our knowledge of those stars was limited. Based on the NASA Space Telescope data, an international team around KU Leuven examined the sounds that emerged in these stars and discovered that …

Tied for ten billionths of a second only – ScienceDaily

Graphene is celebrated as an extraordinary material. It's made of pure carbon, only a single atomic layer thick. Nevertheless, it is extremely stable, strong and even conductive. However, graphene still has significant disadvantages for electronics. It can not be used as a semiconductor because there is no bandgap. By adhering hydrogen atoms to graphene, such a band gap can be …

New effects of the collision that has changed the world – ScienceDaily

When the landmass, now the Indian subcontinent, arrived in Asia some 50 million years ago, the collision changed continent configuration, landscape, global climate, and more. Now, a team of Princeton University scientists has identified another effect: Oxygen in the oceans of the world has increased and changed living conditions. "These results are different from anything people have seen so far," …

Microscopic and molecular evidence at Paleolithic hearths helps uncover Neanderthal mobility habits – ScienceDaily

Ancient fire remains document the movement and settlement patterns of the Neanderthals and indicate specific occupation events. This emerges from a new study published on April 24, 2019 in PLOS ONE by Lucia Leierer and colleagues from the Universidad de La Laguna, Spain. It is believed that most Paleolithic household activities took place around fire pits or fire. The author …
