Chimpanzees use medicinal plants for first aid and hygieneResearchers have observed wild chimpanzees seeking out particular plants, including ones known to have medicinal value, and using them to treat wounds on themselves and others. They also used plants to clean themselves after sex and defecation. Elodie Freymann from Oxford University lived with the chimpanzees in Uganda over eight months and published this research in the journal Frontiers in Ecology and Evolution.Why this evolutionary dead end makes understanding extinction even more difficult540 million years ago, there was an explosion of animal diversity called the Cambrian explosion, when nature experimented with, and winnowed many animal forms into just a few. A new discovery of one of the unlucky ones that didn’t make it has deepened the mystery of why some went extinct, because despite its strangeness, it shows adaptations common to many of the survivors. Joseph Moysiuk, curator of paleontology and geology at the Manitoba Museum helped identify the fossil, and published on it in Royal Society Open Science&nbsp;A quantum computer demonstrates its worth by solving an impossible puzzleImagine taking a sudoku puzzle, handing bits of it to several people, putting them in separate rooms, and asking them to solve the puzzle. A quantum computer using the weird phenomenon of “entanglement” was able to do something analogous to this, which serves as evidence that it really is exploiting quantum strangeness, and could be used for more practical purposes. David Stephen, a physicist at the quantum computing company Quantinuum, and colleagues from the University of Boulder published on this finding in Physical Review Letters.Roadkill shows that most mammals have fluorescent furA researcher who used a range of mammal and marsupial animals killed by vehicles, has demonstrated that the fur of many of these animals exhibit biofluorescence – the ability to absorb light and re-emit it in different wavelengths. They were able to identify some of the fluorescent chemicals, but don’t know why these animals would glow like this. Zoologist Linda Reinhold observed bright colours such as yellow, blue, green and pink on Australian animals like the bandicoot, wallaby, tree-kangaroo, possums and quolls. Their research was published in the journal PLOS One.Science suggests humans are not built for the information ageWe are living in the age of information. In fact, we’re drowning in it. Modern technology has put vast amounts of information at our fingertips, and it turns out that science is showing that humans just aren’t that good at processing all that data, making us vulnerable to bias, misinformation and manipulation.Producer Amanda Buckiewicz spoke to:Friedrich Götz, an Assistant Professor of Psychology at the University of British Columbia.Vasileia Karasavva, a PhD student in the Department of Psychology at the University of British Columbia.Timothy Caulfield, professor in the Faculty of Law and the School of Public Health at the University of Alberta, and was the Canada Research Chair in Health Law and Policy from 2002 - 2023.Eugina Leung, an assistant professor of marketing at the A.B.
