	Webb telescope helps refine Hubble constant, suggesting resolution to long-standing expansion rate debate For the past decade, scientists have been trying to get to the bottom of what seemed like a major inconsistency in the universe. The universe expands over time, but how fast it's expanding has seemed to differ depending on whether you looked early in the universe's history or the present day. If true, this would have presented a major problem to the gold-standard model that represents our best understanding of the universe.
	Targeting the epipharynx to disrupt the residual triggers of COVID-19 in patients with long COVID The COVID-19 pandemic had a profound effect on the world, resulting in a dramatic loss of human lives. While the situation is now largely under control, there are patients who still suffer from the disease and have symptoms lasting for more than three months. The set of these symptoms has been linked to a condition called "long COVID," which persists after an initial period of COVID-19 infection. While the condition is still under study, researchers in Japan have made a significant discovery in the fight against long COVID.
	Five-year study suggests chimpanzees strike stones against trees as form of communication A recent study by behavioral biologists from Wageningen University & Research and the German Primate Research Center has uncovered a remarkable phenomenon among wild chimpanzees in West Africa: the use of stones to produce sound, presumably as a form of communication.
	Sleep disorders and hearing loss share common biological mechanisms, review finds Sleep is known to be central to various physiological and mental processes, including the consolidation of memories, supporting various cognitive functions, helping to clear the brain of neurotoxins, balancing hormones and promoting cardiovascular health. Some recent neuroscience studies also suggest that sleep disorders, such as insomnia, periodic limb movement disorder and sleep apnea, could also be linked to hearing loss.
	From infinite past to future: Simulation tracks complete journey of gravitational wave through black hole spacetime In a new Physical Review Letters study, researchers have successfully followed a gravitational wave's complete journey from the infinite past to the infinite future as it encounters a black hole.
	Mysterious Syrian artifacts reidentified as ancient baby rattles A recent study by Dr. Georges Mouamar and his colleagues investigated the largest assemblage of securely identified rattles in the Near East. The findings are published in the journal Childhood in the Past.
	Autism and ADHD have distinct brain connectivity signatures, study finds Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are among the most well-known neurodevelopmental conditions, estimated to affect approximately 1–3% and 5–7% of the global population, respectively. While people diagnosed with ASD can experience difficulties with social communication, repetitive behaviors and a heightened sensitivity to sensory stimuli (e.g., lights, sounds, etc.), those diagnosed with ADHD are often prone to hyperactivity, impulsivity and inattention, which makes it harder for them to focus on tasks for extended periods of time.
	Robot navigates high-speed parkour with autonomous movement planning A team of roboticists and AI specialists at the Robotics & Artificial Intelligence Lab in Korea has designed, built and successfully tested a four-legged robot that is capable of conducting high-speed parkour maneuvers. In their paper published in the journal Science Robotics, the group describes how they gave their robot a controller capable of both planning and tracking its own movements to allow it to freely traverse a range of environments.
	Chronic renal failure: Discovery of a crucial biomarker In a world first, Canadian scientists at the CRCHUM, the hospital research center affiliated with Université de Montréal, have identified microRNA able to protect small blood vessels and support kidney function after severe injury.
	Webb telescope captures deep view of ancient galaxies The James Webb Space Telescope's deepest view of a single target yet depicts spinning arcs of light that are galaxies from the universe's distant past, the European Space Agency said Tuesday.
	Secrets of the mysterious Gobi wall uncovered A new study sheds new light on one of the least understood segments of medieval Inner Asian infrastructure: the Gobi Wall.
	Robot morphs midair to switch from flying to rolling on terrain Specialized robots that can both fly and drive typically touch down on land before attempting to transform and drive away. But when the landing terrain is rough, these robots sometimes get stuck and are unable to continue operating.
	Ancient bread rises again as Turkey recreates 5,000-year-old loaf In the early Bronze Age, a piece of bread was buried beneath the threshold of a newly built house in what is today central Turkey.
	First-of-its-kind measurement may help physicists learn about gluons, which hold together nuclei in atoms A team of physicists has embarked on a journey where few others have gone: into the glue that binds atomic nuclei. The resultant measurement, which was extracted from experimental data taken at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility, is the first of its kind and will help physicists image particles called gluons.
	The hunt for mysterious 'Planet Nine' offers up a surprise It's an evocative idea that has long bedeviled scientists: a huge and mysterious planet is lurking in the darkness at the edge of our solar system, evading all our efforts to spot it.
	Street smarts: Cooper's hawk uses pedestrian crossing signal to ambush urban prey A University of Tennessee researcher documented an immature Cooper's hawk using vehicle traffic and pedestrian signal patterns as concealment during hunting behavior at a suburban intersection.
	Spleen-based islet transplantation restores glycemic control in type 1 diabetes without full immunosuppression Wenzhou Medical University researchers have reimagined the spleen as a viable site for islet transplantation, enabling long-term diabetes control without the burden of full immunosuppression. Nanoparticle-driven spleen remodeling allowed transplanted mouse, rat, and human islets to restore normal blood sugar in diabetic rodents and cynomolgus macaques.
	Astronomers discover new evidence of intermediate-mass black holes In the world of black holes, there are generally three size categories: stellar-mass black holes (about five to 50 times the mass of the sun), supermassive black holes (millions to billions of times the mass of the sun), and intermediate-mass black holes with masses somewhere in between.
	Vegetarianism linked to values of autonomy and non-conformity The values of vegetarians diverge sharply from those of meat-eaters, revealing a profile less about kindness and more about individuality, according to psychologist John B. Nezlek at SWPS University of Social Sciences and Humanities and the College of William & Mary.
	Cosmic mystery deepens as astronomers find object flashing in both radio waves and X-rays Astronomers from the International Center for Radio Astronomy Research (ICRAR), in collaboration with international teams, have made a startling discovery about a new type of cosmi
