Science X Newsletter Week 46

Dear ,

Here is your customized Science X Newsletter for week 46:

	New plant hardiness map, used by gardeners nationwide, is unveiled The U.S. Department of Agriculture today released its new Plant Hardiness Zone Map, the national standard by which gardeners can determine which plants are most likely to survive the coldest winter temperatures at a certain location.
	Hunter-gatherer approach to childcare suggests that the key to mother and child well-being may be many caregivers Infants and toddlers may be psychologically wired to thrive with high levels of "sensitive care" and personal attention, according to a study conducted with contemporary hunter-gatherer societies.
	Late Prehistoric discovery turns archaeological assumptions on their head For a team of archaeologists digging in southwest Spain, the discovery of a Bronze/Iron Age stela—a funerary stone slab with carvings depicting an important individual—would have been exciting enough. But to find a stela that challenges longstanding interpretations of how the carvings represent gender and social roles in prehistoric times was beyond the teams' wildest dreams.
	New research suggests plants might be able to absorb more CO2 from human activities than previously expected New research published in Science Advances paints an uncharacteristically upbeat picture for the planet. This is because more realistic ecological modeling suggests the world's plants may be able to take up more atmospheric CO2 from human activities than previously predicted.
	New research maps 14 potential evolutionary dead ends for humanity and ways to avoid them For the first time, scientists have used the concept of evolutionary traps on human societies at large. They find that humankind risks getting stuck in 14 evolutionary dead ends, ranging from global climate tipping points to misaligned artificial intelligence, chemical pollution, and accelerating infectious diseases.
	Researchers reveal that Earth's surface water can penetrate deep into the planet, transforming core's outer layer A few decades ago, seismologists imaging the deep planet identified a thin layer, just over a few hundred kilometers thick. The origin of this layer, known as the E prime layer, has been a mystery—until now.
	Scientists uncover aurora-like radio emission above a sunspot In a study published in Nature Astronomy, astronomers from New Jersey Institute of Technology's Center for Solar-Terrestrial Research (NJIT-CSTR) have detailed radio observations of an extraordinary aurora-like display occurring 40,000 km above a relatively dark and cold patch on the sun, known as a sunspot.
	Early-life stress changes more genes in the brain than a head injury A surprising thing happened when researchers began exploring whether early-life stress compounds the effects of a childhood head injury on health and behavior later in life. In an animal study, stress changed the activation level of many more genes in the brain than were changed by a bump to the head.
	Brightest flash ever disturbed Earth's atmosphere last year Last year the brightest flash of light ever seen in the night sky disturbed Earth's upper atmosphere in a way that has never before detected before, researchers said on Tuesday.
	Phosphorous discovered in outskirts of the Milky Way for the first time A trio of chemists at the University of Arizona, with an affiliation to the University of Arizona's Department of Astronomy and Steward Observatory has discovered phosphorous in the outskirts of the Milky Way galaxy for the first time. In their project, reported in the journal Nature, Lilia Koelemay, Karlie Gold and Lucy Ziurys studied the gas cloud WB89-621.
	Study resolves puzzles in gravitational collapse of gravitational waves Black holes are regions in space where the gravitational pull is so strong that nothing can escape them, not even light. These fascinating regions have been the focus of countless studies, yet some of the physics underlying their formation is not yet fully understood.
	The 'liking gap' is real for second language English speakers, research shows A study from Concordia's Applied Linguistics Lab suggests that most people are usually overly harsh on themselves when speaking in a second language.
	Forensic scientists help locate missing Second World War pilot after eight decades On a summer's day in July 1943, a U.S. B-25 Mitchell bomber left Tunisia in North Africa on a mission to attack the Sciacca Aerodrome in Sicily, Italy.
	SpaceX launched its giant new rocket but explosions end the second test flight SpaceX launched its mega rocket Starship but lost both the booster and the spacecraft in a pair of explosions minutes into Saturday's test flight.
	Big bang: Dutch firm eyes space baby Climate crises, nuclear Armageddon, or a sudden meteor strike—it's clear humanity could do with Planet B. But first we need to learn to reproduce safely in space, says Dutch entrepreneur Egbert Edelbroek.
	Neuroscientists engineer a protein that enhances memory to respond to anti-aging drug Neuroscientists at the Faculty of Medicine and Surgery of the Catholic University, Rome, and the Fondazione Policlinico Universitario Agostino Gemelli IRCCS have genetically modified a molecule, the protein LIMK1, which is normally active in the brain, with a key role in memory. They added a "molecular switch" that is activated by administering a drug, rapamycin, known for its several anti-aging effects on the brain.
	AI faces look more real than actual human face: Study White faces generated by artificial intelligence (AI) now appear more real than human faces, according to new research led by experts at The Australian National University (ANU).
	Second-most distant galaxy discovered using James Webb Space Telescope The second- and fourth-most distant galaxies ever observed have been discovered in a region of space known as Pandora's Cluster, or Abell 2744, using data from NASA's James Webb Space Telescope (JWST).
	Autonomous lab discovers best-in-class quantum dot in hours. It would have taken humans years It can take years of focused laboratory work to determine how to make the highest quality materials for use in electronic and photonic devices. Researchers have now developed an autonomous system that can identify how to synthesize "best-in-class" materials for specific applications in hours or days.
	New study shows ancient Europe was not all forest, half was covered in grassland A team of ecologists, biologists, geographers, geologists and Earth scientists from across Europe, working with a colleague from the U.K. and another from Canada, has found evidence suggesting that Europe was not covered heavily by forest during the Last Interglacial period, as many have suggested, but was instead half grassland. In their project, published in the journal Science Advances, the group studied pollen samples collected over many years at dig sites across Europe.
