 Dear olivier hartmanshenn,

Here is your customized Science X Newsletter for week 11:

	Americas to witness rare 'blood moon' total lunar eclipse Stargazers in North and South America will be able to view a red-colored "blood moon" starting Thursday night in the first total lunar eclipse visible on the continents since 2022.
	Research reveals humans struggle to accurately read dogs' emotions Life with a dog is a matter of give and take. Especially when it comes to communication. With no common human–dog language, our ability to communicate relies on understanding and reading our pet, and vice versa. That process can seem seamless. You give your dog a treat, you look into her eyes and she says "I am delighted to have that cookie." With a slight wag of her tail, she accepts the treat and romps off to another room to enjoy it. You feel connected to your dog.
	Male blue-lined octopuses paralyze females before mating to prevent being eaten A team of neurologists, environmentalists and bioengineers at the University of Queensland, in Australia, has found that male blue-lined octopuses paralyze females prior to mating to avoid being eaten. In their study published in the journal Current Biology, the group captured several octopus samples and studied their behavior and vital signs as they mated.
	Why does nature love spirals? The link to entropy There are moments in the history of human thought when a simple realization transforms our understanding of reality. A moment when chaos reveals itself as structure, when disorder folds into meaning, and when what seemed like an arbitrary universe unveils itself as a system governed by hidden symmetries.
	Quantum tornadoes in momentum space: First experimental proof of a new quantum phenomenon Researchers from Würzburg have experimentally demonstrated a quantum tornado for the first time by refining an established method. In the quantum semimetal tantalum arsenide (TaAs), electrons in momentum space behave like a swirling vortex. This quantum phenomenon was first predicted eight years ago by a Dresden-based founding member of the Cluster of Excellence ct.qmat.
	Genomic study indicates our capacity for language emerged 135,000 years ago It is a deep question, from deep in our history: when did human language as we know it emerge? A new survey of genomic evidence suggests our unique language capacity was present at least 135,000 years ago. Subsequently, language might have entered social use 100,000 years ago.
	Puzzling observation by JWST: Galaxies in the deep universe rotate in the same direction In just over three years since its launch, NASA's James Webb Space Telescope (JWST) has generated significant and unprecedented insights into the far reaches of space, and a new study by a Kansas State University researcher provides one of the simplest and most puzzling observations of the deep universe yet.
	Violent supernovae 'triggered at least two Earth extinctions,' study suggests At least two mass extinction events in Earth's history were likely caused by the "devastating" effects of nearby supernova explosions, a new study suggests.
	New map of landscape beneath Antarctica unveiled The most detailed map yet of the landscape beneath Antarctica's ice sheet has been assembled by a team of international scientists led from the British Antarctic Survey (BAS).
	Mathematicians move the needle on the Kakeya conjecture, a decades-old geometric problem Mathematicians from New York University and the University of British Columbia have resolved a decades-old geometric problem, the Kakeya conjecture in 3D, which studies the shape left behind by a needle moving in multiple directions.
	Scientists break down plastic using a simple, inexpensive catalyst and air Harnessing moisture from air, Northwestern University chemists have developed a simple new method for breaking down plastic waste.
	East Asian human gene that allows adult humans to digest sugars in milk likely came from Neanderthals A small team of computational and evolutionary biologists from the University of Chinese Academy of Sciences, Zhongshan Hospital and the Max Planck Institute for Evolutionary Anthropology, reports that unique lactase genes carried by about 25% of East Asian people may have been inherited from Neanderthals.
	First burials: Compelling evidence that Neanderthal and Homo sapiens engaged in cultural exchange The first-ever published research on Tinshemet Cave reveals that Neanderthals and Homo sapiens in the mid-Middle Paleolithic Levant not only coexisted but actively interacted, sharing technology, lifestyles, and burial customs. These interactions fostered cultural exchange, social complexity, and behavioral innovations, such as formal burial practices and the symbolic use of ocher for decoration.
	Did UCLA just cure baldness? How geneticists are reawakening hibernating follicles Ancient Egyptians rubbed their bald heads with a mixture of dates, dog's paw and donkey's hoof; Celtic cures involved mice in a jar. Native Americans turned to yucca juice. Throughout human history, there have been a number of existential quests: for knowledge, for peace, for riches—and for a cure for baldness.
	Smell like a god: Ancient sculptures were scented, Danish study shows Science has already proven that sculptures from ancient Greece and Rome were often painted in warm colors, and now a Danish study has revealed that some were also perfumed.
	Appropriate use of humor can make science communication more effective, study suggests Authoritative, intelligent, responsible, serious—if you were asked to describe the general figure of a scientist, you would probably use adjectives like these. However, "funny" would likely not be the first word that comes to mind. Scientists, in fact, rarely adopt a humorous tone when communicating with the public, perhaps out of fear of appearing less credible.
	Supercomputer draws molecular blueprint for repairing damaged DNA Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren't just skin deep. Inside the body, DNA is literally being torn apart.
	'You don't just throw them in a box.' Archaeologists and Indigenous scholars call for better care of animal remains Two years ago, Chance Ward began opening boxes of horse remains that had been shipped to the University of Colorado Museum of Natural History from other institutions around the country. What he saw made his heart sink.
	Permian mass extinction linked to 10°C global temperature rise that reshaped Earth's ecosystems The mass extinction that ended the Permian geological epoch, 252 million years ago, wiped out most animals living on Earth. Huge volcanoes erupted, releasing 100,000 billion metric tons of carbon dioxide into the atmosphere. This destabilized the climate and the carbon cycle, leading to dramatic global warming, deoxygenated oceans, and mass extinction.
	Quantum entanglement wins: Researchers report quantum advantage in a simple cooperation game Quantum systems hold the promise of tackling some complex problems faster and more efficiently than classical computers. Despite their potential, so far only a limited number of studies have conclusively demonstrated that quantum computers can outperform classical computers on specific tasks. Most of these studies focused on tasks that involve advanced computations, simulations or optimization, which can be difficult for non-experts to grasp.
