  Dear olivier hartmanshenn,

  Here is your customized Science X Newsletter for week 13:

  	High‑dose vitamin D significantly reduces disease activity in early multiple sclerosis onset, clinical trial finds Researchers from CHU Nîmes, Université Montpellier, and multiple MS centers in France have found that oral cholecalciferol in doses of 100,000 IU every two weeks significantly reduced disease activity in clinically isolated syndrome and early relapsing‑remitting multiple sclerosis.
  	A breakthrough moment: Researchers discover new class of antibiotics The last time a new class of antibiotics reached the market was nearly three decades ago—but that could soon change, thanks to a discovery by researchers at McMaster University.
  	Organic molecules of unprecedented size discovered on Mars Scientists analyzing pulverized rock onboard NASA's Curiosity rover have found the largest organic compounds on the red planet to date. The finding, published Monday in the Proceedings of the National Academy of Sciences, suggests prebiotic chemistry may have advanced further on Mars than previously observed.
  	Marathon runners undergo reversible reductions in myelin in the brain during a race, study reveals A team of neurologists, neuroradiologists and biomaterials specialists affiliated with several institutions in Spain has found that marathon runners undergo a reversible reduction in myelin in the brain during a race. In their study published in the journal Nature Metabolism, the group analyzed MRI scans of marathon runners before and after a race and then at later intervals to learn more about how participating in long races impacts the brain.
  	Theoretical physicists completely determine the statistics of quantum entanglement For the first time, theoretical physicists from the Institute of Theoretical Physics (IPhT) in Paris-Saclay have completely determined the statistics that can be generated by a system using quantum entanglement. This achievement paves the way for exhaustive test procedures for quantum devices.
  	Ecosystem disrupted following the disappearance of great white sharks, study finds Known for their powerful ability to launch out of the water in pursuit of prey, the loss of great white sharks from False Bay in South Africa has scientists and conservationists concerned about the rippling effects on the ecosystem.
  	Arctic sea ice hits record low for its usual peak growth period Arctic sea ice had its weakest winter buildup since record-keeping began 47 years ago, a symptom of climate change that will have repercussions globally, scientists said Thursday.
  	New study reveals protector protein that supports hair regrowth in adults Alopecia is an autoimmune disorder that causes non-scarring hair loss on the scalp and body that is experienced by almost 2% of the global population at some point in their lifetime.
  	The US has the power to switch off the UK's nuclear subs, posing a security issue Prime Minister Keir Starmer recently boarded one of the UK's four nuclear-armed submarines for a photo call as part of his attempts to demonstrate the UK's defense capabilities as tensions with Russia continue.
  	Physicist revisits the computational limits of life and Schrödinger's essential question in the era of quantum computing More than 80 years ago, Erwin Schrödinger, a theoretical physicist steeped in the philosophy of Schopenhauer and the Upanishads, delivered a series of public lectures at Trinity College, Dublin, which eventually came to be published in 1944 under the title "What is Life?"
  	After 7,000 years without light and oxygen in Baltic Sea mud, researchers bring prehistoric algae back to life A research team led by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) was able to revive dormant stages of algae that sank to the bottom of the Baltic Sea almost 7,000 years ago. Despite thousands of years of inactivity in the sediment without light and oxygen, the investigated diatom species regained full viability.
  	Megastudy finds a simple way to boost math progress American students have been falling behind in math for decades—with test scores that consistently rank in the bottom 25% globally compared to students in other developed countries—and the COVID-19 pandemic made the situation worse.
  	Human retinal stem-like cells with potential to repair vision loss discovered Wenzhou Medical University and collaborating institutions have identified a population of human neural retinal stem-like cells able to regenerate retinal tissue and support visual recovery.
  	Quantum computing milestone: 56-qubit computer provides truly random number generation In a new paper in Nature, a team of researchers from JPMorganChase, Quantinuum, Argonne National Laboratory, Oak Ridge National Laboratory and The University of Texas at Austin describe a milestone in the field of quantum computing, with potential applications in cryptography, fairness and privacy.
  	Why humans have smaller faces than Neanderthals The human face is strikingly distinct from our fossil cousins and ancestors—most notably, it is significantly smaller, and more gracile. However, the reasons behind this change remain largely unknown. A team of researchers led by the Max Planck Institute for Evolutionary Anthropology has investigated why and how our species evolved such a unique facial form.
  	Commercial fusion power plant now closer to reality Successfully harnessing the power of fusion energy could lead to cleaner and safer energy for all—and contribute substantially to combating the climate crisis. Towards this goal, Type One Energy has published a comprehensive, self-consistent, and robust physics basis for a practical fusion pilot power plant.
  	Even atheists in secular countries show intuitive preferences for religious belief New research published in the Proceedings of the National Academy of Sciences reveals that atheists in some of the world's most secular countries show an intuitive preference for religious belief over atheism.
  	3D nanotech blankets offer new path to clean drinking water Researchers have developed a new material that, by harnessing the power of sunlight, can clear water of dangerous pollutants. Created through a combination of soft chemistry gels and electrospinning—a technique where electrical force is applied to liquid to craft small fibers—the team constructed thin fiber-like strips of titanium dioxide (TiO₂), a compound often utilized in solar cells, gas sensors and various self-cleaning technologies.
  	Earth's storage of water in soil, lakes and rivers is dwindling. And it's especially bad for farming University of Melbourne hydrology professor Dongryeol Ryu and his collaborator Ki-Weon Seo were on a train to visit Ryu's family when they found something startling. Stopped at a station for technical issues, Seo had pulled out his computer to pass the time with some work when a result popped up in their data that Ryu could hardly believe: It suggested a "remarkable" amount of Earth's water stored on land had been depleted.
  	'Half ice, half fire': Physicists discover new phase of matter in a magnetic material Two scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have discovered a new phase of matter while studying a
