Dear olivier hartmanshenn,

Here is your customized Science X Newsletter for week 24:

	Physicists confirm quantum entanglement persists between top quarks, the heaviest known fundamental particles An experiment by a group of physicists led by University of Rochester physics professor Regina Demina has produced a significant result related to quantum entanglement—an effect that Albert Einstein called "spooky action at a distance."
	Study confirms the rotation of Earth's inner core has slowed University of Southern California scientists have proven that the Earth's inner core is backtracking—slowing down—in relation to the planet's surface, as shown in new research published in Nature.
	Astrophysicists calculate the likelihood that Earth was exposed to cold harsh interstellar clouds 2 million years ago Around two million years ago, Earth was a very different place, with our early human ancestors living alongside saber-toothed tigers, mastodons, and enormous rodents. And, depending on where they were, they may have been cold: Earth had fallen into a deep freeze, with multiple ice ages coming and going until about 12,000 years ago.
	Satellite 'megaconstellations' may jeopardize recovery of ozone hole When old satellites fall into Earth's atmosphere and burn up, they leave behind tiny particles of aluminum oxide, which eat away at Earth's protective ozone layer. A new study finds that these oxides have increased 8-fold between 2016 and 2022 and will continue to accumulate as the number of low-Earth-orbit satellites skyrockets.
	Satellite data reveal anomalies up to 19 days before 2023 Turkey earthquake Earthquakes may betray their impending presence much earlier than previously thought through a variety of anomalies present in the ground, atmosphere and ionosphere that can be detected using satellites, a recent study in the Journal of Applied Geodesy suggests.
	Einstein Telescope could launch a new era in astronomy It's still just a plan, but a new telescope could soon be measuring gravitational waves. Gravitational waves are something like the sound waves of the universe. They are created, for example, when black holes or neutron stars collide.
	How does light interact with matter at extreme intensities, near the Schwinger limit? The experimental generation of increasingly intense light beams could help to unveil new physical regimes occurring in the presence of very strong electromagnetic fields. While some progress has been made towards this goal, physicists are yet to develop a reliable strategy to achieve extreme light intensities.
	Siberia's 'mammoth graveyard' reveals 800-year human interactions with woolly beasts Woolly mammoths are evocative of a bygone era, when Earth was gripped within an Ice Age. Current knowledge places early mammoth ancestors in the Pliocene (2.58–5.33 million years ago, Ma) before their populations expanded in the Pleistocene (2.58 Ma–11,700 years ago, kyr). However, as climate changed, their numbers dwindled to isolated populations in modern Siberia and Alaska, until their last dated survival 4 kyr ago.
	Remember they said Miami would be under water? A preview of the future It's like an unspoken social contract. When people choose to live in South Florida, they must make peace with the possibility that, thanks to hurricanes, there will be flooding and they may incur thousands of dollars to fix their homes post storm.
	New study reveals brain's fractal-like structure near phase transition, a finding that may be universal across species When a magnet is heated up, it reaches a critical point where it loses magnetization. Called "criticality," this point of high complexity is reached when a physical object is transitioning smoothly from one phase into the next.
	Researchers map genome of the last living wild horse species University of Minnesota researchers have successfully mapped the complete genome of the endangered Przewalski's horse. Once extinct in the wild, the species now has a population of around 2,000 animals thanks to conservation efforts.
	Advanced underwater robots discover deep-sea squid that broods giant eggs The deep sea is the largest living space on Earth, but many of the animals and habitats far beneath the ocean's surface remain shrouded in mystery. MBARI's advanced underwater robots, including remotely operated vehicles (ROVs), are helping survey life in the ocean's depths.
	Quantum entangled photons react to Earth's spin A team of researchers led by Philip Walther at the University of Vienna carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work, published in Science Advances, represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity.
	First detection of frost on the solar system's tallest volcanoes on Mars For the first time, water frost has been detected on the colossal volcanoes on Mars, which are the largest mountains in the solar system. The international team led by the University of Bern used high-resolution color images from the Bernese Mars camera, CaSSIS, onboard the European Space Agency's ExoMars Trace Gas Orbiter spacecraft. Understanding where water can be found, and how it is transported, is relevant for future Mars missions and possible human exploration.
	New veggie piranha-like species named after Tolkien villain A new vegetarian piranha-like species discovered by scientists in the Brazilian Amazon has been named Sauron after the Lord of the Rings villain, Britain's Natural History Museum said on Tuesday.
	Scientists unlock secrets of how the third form of life makes energy An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas.
	Novel quantum sensor breaks limits of optical measurement using entanglement The Korea Research Institute of Standards and Science (KRISS) has developed a novel quantum sensor technology that allows the measurement of perturbations in the infrared region with visible light by leveraging the phenomenon of quantum entanglement. This will enable low-cost, high-performance IR optical measurement, which previously accompanied limitations in delivering quality results.
	Scientists make and test efficient water-splitting catalyst predicted by theory Hydrogen (H2) is a promising fuel for reducing greenhouse gases, especially if produced by using renewable energy to split water molecules (H2O). But as simple as it may seem to break water into hydrogen and oxygen, the chemistry is complex.
	Webb Telescope reveals asteroid collision in neighboring star system Astronomers have captured what appears to be a snapshot of a massive collision of giant asteroids in Beta Pictoris, a neighboring star system known for its early age and tumultuous planet-forming activity.
	Hubble Space Telescope finds surprises around a star that erupted 40 years ago Astronomers have used new data from NASA's Hubble Space Telescope and the retired SOFIA (Stratospheric Observatory for Infrared Astronomy) as well as archival data from other missions to
