Dear olivier hartmanshenn,

Here is your customized Science X Newsletter for week 26:

	Humans' ancestors survived the asteroid impact that killed the dinosaurs, shows fossil record analysis A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.
	Ninth Dedekind number discovered: Scientists solve long-known problem in mathematics Making history with 42 digits, scientists at Paderborn University and KU Leuven have unlocked a decades-old mystery of mathematics with the so-called ninth Dedekind number.
	Scientists find key evidence for existence of nanohertz gravitational waves A group of Chinese scientists has recently found key evidence for the existence of nanohertz gravitational waves, marking a new era in nanohertz gravitational wave research. The research was based on pulsar timing observations carried out with the Five-hundred-meter Aperture Spherical radio Telescope (FAST).
	New image from James Webb Space Telescope reveals astonishing Saturn and its rings Get ready to be amazed by the latest James Webb Space Telescope (JWST) image. Saturn's iconic rings seem to glow eerily in this incredible infrared picture, which also unveils unexpected features in Saturn's atmosphere.
	Combining math with music leads to higher test scores, according to review of 50 years of research Children do better at math when music is a key part of their lessons, an analysis of almost 50 years of research on the topic has revealed.
	NASA's Mars helicopter 'phones home' after no contact for 63 days Long time, no speak: NASA has re-established contact with the intrepid Ingenuity Mars Helicopter after more than two months of radio silence, the space agency said Friday.
	New analysis of tooth minerals confirms megalodon shark was warm-blooded The largest marine predator that ever lived was no cold-blooded killer. A new analysis by environmental scientists from UCLA, UC Merced and William Paterson University sheds light on the warm-blooded animal's ability to regulate its body temperature—and might help explain why it went extinct.
	Orangutans can make two sounds at the same time, similar to human beatboxing, study finds Orangutans can make two separate sounds simultaneously, much like songbirds or human beatboxers, according to a study led by the University of Warwick. The paper, "Wild orangutans can simultaneously use two independent vocal sound sources similarly to songbirds and human beatboxers," is published by PNAS Nexus.
	Economic inequality cannot be explained by individual bad choices, study finds A global study led by a researcher at Columbia University Mailman School of Public Health and published in the journal Scientific Reports finds that economic inequality on a social level cannot be explained by bad choices among the poor nor by good decisions among the rich. Poor decisions were the same across all income groups, including for people who have overcome poverty.
	Hidden in plain sight: Rare palm species that flowers underground discovered in Borneo In a new study, researchers at the Royal Botanic Gardens, Kew and partners have described the only known member of the palm family (Arecaceae) to flower and fruit almost entirely underground. Owing to this unusual characteristic, the scientists have named the species Pinanga subterranea, with its species name derived from the Latin word for underground. The work was published in the journal PALMS with added commentary in Plants, People, Planet.
	Clamor of gravitational waves from universe's merging supermassive black holes 'heard' for first time Following 15 years of data collection in a galaxy-sized experiment, scientists have "heard" the perpetual chorus of gravitational waves rippling through our universe for the first time—and it's louder than expected.
	Humans' evolutionary relatives butchered one another 1.45 million years ago Researchers from the Smithsonian's National Museum of Natural History have identified the oldest decisive evidence of humans' close evolutionary relatives butchering and likely eating one another.
	Researchers uncover new CRISPR-like system in animals that can edit the human genome A team of researchers led by Feng Zhang at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT has uncovered the first programmable RNA-guided system in eukaryotes—organisms that include fungi, plants, and animals.
	Astrophysicists propose a new way of measuring cosmic expansion: lensed gravitational waves The universe is expanding; we've had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate.
	Reading for pleasure early in childhood linked to better cognitive performance and mental well-being in adolescence Children who begin reading for pleasure early in life tend to perform better at cognitive tests and have better mental health when they enter adolescence, a study of more than 10,000 young adolescents in the U.S. has found.
	New ferroelectric material could give robots muscles A new type of ferroelectric polymer that is exceptionally good at converting electrical energy into mechanical strain holds promise as a high-performance motion controller or "actuator" with great potential for applications in medical devices, advanced robotics, and precision positioning systems, according to a team of international researchers led by Penn State.
	Remote lake emissions from the Tibetan Plateau challenge global climate modeling Earth's complex systems interact between atmospheric, terrestrial, hydrological, cryological (ice and snow) and biological processes in feedback loops. Understanding their relationships is important for modeling their future impacts, particularly regarding climate change.
	Research students turn Schrödinger's cat on its head Students at the Faculty of Physics of the University of Warsaw (UW) and researchers from the QOT Center for Quantum Optical Technologies have developed an innovative method that allows the fractional Fourier Transform of optical pulses to be performed using quantum memory. This achievement is unique on the global scale, as the team was the first to present an experimental implementation of the said transformation in this type of system.
	Shattering the myth of men as hunters and women as gatherers Analysis of data from dozens of foraging societies around the world shows that women hunt in at least 79% of these societies, opposing the widespread belief that men exclusively hunt and women exclusively gather. Abigail Anderson of Seattle Pacific University, US, and colleagues presented these findings in the open-access journal PLOS ONE on June 28, 2023.
	Study reveals reason hellbenders are disappearing The gigantic, slimy salamanders known as hellbenders, once the apex predators of many freshwater streams, have been in decline for decades, their population constantly shrinking. No one knew why. William Hopkins, professor in the Department of Fish and Wildlife Conservation and director of the Global Change Center at Virginia Tech, suspected the hellbenders' plight had connections with environmental changes engineered by humans.
