Dear olivier hartmanshenn,

Here is your customized Science X Newsletter for week 29:

	Study finds regular 'phubbing' could be damaging marriages A pair of psychologists at Niğde Ömer Halisdemir University, has found evidence showing that married couples who regularly engage in phone snubbing (phubbing) have lower marriage satisfaction than couples who do not. In their study, reported in the journal Computers in Human Behavior, Suat Kılıçarslan and İzzet Parmaksız sent questionnaires to married couples in Turkey and compiled results from those that were returned.
	'Stunning' discovery: Metals can heal themselves Scientists for the first time have witnessed pieces of metal crack, then fuse back together without any human intervention, overturning fundamental scientific theories in the process. If the newly discovered phenomenon can be harnessed, it could usher in an engineering revolution—one in which self-healing engines, bridges and airplanes could reverse damage caused by wear and tear, making them safer and longer-lasting.
	The cost of being a non-native English speaker in science English serves as a convenient, common language for science. However, this practice poses insurmountable barriers to those whose first language is not English—the majority of people around the world.
	Scientists discover filter-feeding basking sharks are warm-bodied like great whites Approximately 99.9% of fish and shark species are "cold-blooded," meaning their body tissues generally match the temperature of the water they swim in—but researchers have just discovered the mighty basking shark is a one-in-a-thousand exception. Instead, these sharks keep the core regions of their bodies warmer than the water like the most athletic swimmers in the sea such as great white sharks, mako sharks and tuna.
	Device makes hydrogen from sunlight with record efficiency Rice University engineers can turn sunlight into hydrogen with record-breaking efficiency thanks to a device that combines next-generation halide perovskite semiconductors with electrocatalysts in a single, durable, cost-effective and scalable device.
	Early humans were weapon woodwork experts, study finds A 300,000-year-old hunting weapon has shone a new light on early humans as woodworking masters, according to a new study.
	The Pacific slope of Peru is greening, but it's not good news Research led by physicists and geographers at the University of Cambridge has unveiled some large-scale changes in the vegetation in the South American Andes which may have dramatic impact on the environment and ecosystems of the region.
	NASA's first new wind tunnel in 40 years will turn science fiction to fact Flying cars. Space tourism. Safe reentry for astronauts coming back from Mars.
	ChatGPT justifies liberal leanings with its own values, researcher reports ChatGPT, the artificial intelligence (AI) chatbot developed by the company OpenAI, has a self-declared human alter ego. Her name is Maya, she's 35 years old and hails from a middle-class family in a suburban town in the United States. Maya is a successful software engineer who values self-direction, achievement, creativity and independence. She is also undeniably liberal.
	Researchers make progress toward a new environmentally friendly nanomaterial that could revolutionize electronic devices A team of researchers from the Instituto de Carboquímica of the Spanish National Research Council (CSIC) has made a remarkable step forward in the development of efficient and sustainable electronic devices. They have found a special combination of two extraordinary nanomaterials that successfully results in a new hybrid product capable of turning light into electricity, and vice-versa, faster than conventional materials.
	Scientists use supercomputer to learn how cicada wings kill bacteria Over the past decade, teams of engineers, chemists and biologists have analyzed the physical and chemical properties of cicada wings, hoping to unlock the secret of their ability to kill microbes on contact. If this function of nature can be replicated by science, it may lead to development of new products with inherently antibacterial surfaces that are more effective than current chemical treatments.
	A quantum radar that outperforms classical radar by 20% Quantum technologies, a wide range of devices that operate by leveraging the principles of quantum mechanics, could significantly outperform classical devices on some tasks. Physicists and engineers worldwide have thus been working hard to achieve this long-sought "quantum advantage" over classical computing approaches.
	Shrinking light: Waveguiding scheme enables highly confined subnanometer optical fields Imagine shrinking light down to the size of a tiny water molecule, unlocking a world of quantum possibilities. This has been a long-held dream in the realms of light science and technology. Recent advancements have brought us closer to achieving this incredible feat, as researchers from Zhejiang University have made groundbreaking progress in confining light to subnanometer scales.
	The puzzle of the galaxy with no dark matter A team of scientists, led by the researcher at the IAC and the University of La Laguna (ULL) Sebastién Comerón, has found that the galaxy NGC 1277 does not contain dark matter. This is the first time that a massive galaxy (it has a mass several times that of the Milky Way) has not shown evidence for this invisible component of the universe. "This result does not fit in with the currently accepted cosmological models, which include dark matter," explains Comerón.
	Researchers operating Gamma-ray Burst Monitor discover brightest gamma-ray burst ever detected The University of Alabama in Huntsville (UAH) has announced that three researchers associated with the UAH Center for Space Plasma and Aeronomic Research (CSPAR) have discovered a gamma-ray burst (GRB) approximately 2.4 billion light-years away in the constellation Sagitta that ranks as the brightest ever observed. Believed to have been triggered by collapse of a massive star, it is accompanied by a supernova explosion, giving birth to a black hole.
	Bite your nails or pick at your skin? A new study has a solution for that If you just can't stop biting your nails, picking at your skin or pulling out a hank of hair, especially when you're stressed out, here's something to try that just might work.
	Psychological study suggests arithmetic is biologically-based and a natural consequence of our perception Everyone knows that 2 + 2 = 4, but why do we have arithmetic in the first place, and why is it true? Researchers at the University of Canterbury have recently answered these questions by "reverse engineering" arithmetic from a psychological perspective. To do this, they considered all possible ways that quantities could be combined, and proved (for the first time in mathematical terms) that addition and multiplication are the simplest.
	Astronomers discover striking evidence of 'unusual' stellar evolution Astronomers have found evidence that some stars boast unexpectedly strong surface magnetic fields, a discovery that challenges current models of how they evolve.
	'Mind controlling' parasitic worms are missing genes found in every other animal, researchers find In a world full of bizarre animals, hairworms are some of the strangest. Hairworms are parasitic worms that manipulate the behavior of their hosts in what's sometimes called "mind control."
	Two-faced star exposed: Unusual white dwarf with a hydrogen side and a helium side In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two faced. One side of the white dwarf is composed of hydrogen, while the other is m
