 Dear olivier hartmanshenn,

Here is your customized Science X Newsletter for week 34:

	Mitochondrial antioxidant found to drive breast cancer metastasis The mitochondria may be the powerhouse of the cell, but mounting evidence suggests this organelle is also a driving force behind cancer. Now, new evidence points to the mitochondrial metabolite glutathione, highlighting its central role in helping breast cancer cells break away from the primary tumor, travel through the body, and take root in other tissues.
	GLP-1 drugs linked to reduced symptoms in chronic skin condition hidradenitis suppurativa A multicenter French study led by Rennes University Hospital reports potential benefits of glucagon-like peptide-1 receptor agonists for hidradenitis suppurativa (HS), with statistically significant reductions in HS-related scores at six months and at last follow-up.
	Synthesis of a molecule found in guava plants offers hope in fighting liver-related cancers You may not be aware that most of the medicines that have been approved for treatment are rooted in nature. For example, the bark of willow trees has been called nature's aspirin because it contains a chemical called salicin. The human body converts salicin into salicylic acid, which relieves pain and fights fevers.
	Mystery Greek hominin skull dated to be at least 286,000 years old Research led by Institut de Paléontologie Humaine is providing a finite minimum age for a nearly complete cranium from Petralona Cave in Greece that has perplexed researchers since its discovery in 1960.
	An alternative to LASIK—without the lasers Millions of Americans have altered vision, ranging from blurriness to blindness. But not everyone wants to wear prescription glasses or contact lenses. Accordingly, hundreds of thousands of people undergo corrective eye surgery each year, including LASIK—a laser-assisted surgery that reshapes the cornea and corrects vision.
	For apes, out of sight isn't out of mind: Bonobos can mentally track multiple members of their social circle A series of hide-and-seek experiments with a bonobo named Kanzi shows for the first time that apes can mentally keep track of multiple familiar humans at once, even when they are out of sight.
	Single quantum device that measures amperes, volts and ohms could revolutionize how we measure electricity A team of scientists has revealed how a single quantum device can accurately measure the three fundamental units of electricity—the ampere (unit of electrical current), the volt (unit of electrical potential) and the ohm (unit of electrical resistance). This is a significant breakthrough because until now, no single instrument could measure all three primary electrical units in one practical system. It means that making electrical measurements could be more precise and reduce the potential for human error.
	Majority of chronic pain patients found to discontinue medical cannabis within one year More than half of patients prescribed medical cannabis for chronic musculoskeletal pain stop using it within a year, according to new research from Philadelphia that raises fresh questions about the drug's longevity and its role in long-term pain management—especially among older adults.
	Ionic liquids turn whole organs transparent like glass while preserving intricate tissue details Scientists have found a way to visualize delicate organs like the brain and heart by letting light into the tissues and exposing their inner workings, no dissection required. In their study published in Cell, Chinese researchers introduce a new technique for converting biological tissue into a transparent and glass-like state, making it easier to visualize how biological tissues interact with each other at a microscopic level with exceptional resolution.
	Brain abnormalities seen in children exposed prenatally to widely used pesticide A new study reports evidence of a link between prenatal exposure to the widely used insecticide chlorpyrifos (CPF) and structural abnormalities in the brain and poorer motor function in New York City children and adolescents.
	Accidental double zoom reveals millimeter waves around supermassive black hole An international team of astronomers led by Matus Rybak (Leiden University, Netherlands) has proven, thanks to accidental double zoom, that millimeter radiation is generated close to the core of a supermassive black hole. Their findings have been accepted for publication in the journal Astronomy & Astrophysics and are available on the arXiv preprint server.
	What happened before the Big Bang? Computational method may provide answers We're often told it is "unscientific" or "meaningless" to ask what happened before the Big Bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy Clough, of Queen Mary University of London, UK, and Josu Aurrekoetxea, at Oxford University, UK, published in Living Reviews in Relativity, proposes a way forward: using complex computer simulations to numerically (rather than exactly) solve Einstein's equations for gravity in extreme situations.
	Prehistoric female miners identified using multidisciplinary approach Almost three decades ago, the chert mining area in Krumlov Forest was discovered. Since then, much has been written about the mining activity that took place here. While chert mining occurred here from as early as the beginning of the Holocene until the Early Iron Age, it was not a particularly widespread activity.
	Parker Solar Probe confirms decades-old theoretical models about magnetic reconnection New research led by Southwest Research Institute (SwRI) has confirmed decades-old theoretical models of magnetic reconnection, the process that releases stored magnetic energy to drive solar flares, coronal mass ejections and other space weather phenomena. The data was captured by NASA's Parker Solar Probe (PSP), which is the only spacecraft to have flown through the sun's upper atmosphere.
	Restricted blood flow speeds tumor growth by aging the immune system, study finds Cutting off blood flow can prematurely age the bone marrow, weakening the immune system's ability to fight cancer, according to a new study from NYU Langone Health.
	Fish tracks show earliest adaptations for moving on land The Polish Geological Institute-National Research Institute reports a Lower Devonian (419 to 393 million years ago) fossilized trackway in the Holy Cross Mountains, Poland, attributed to dipnoan fish. Their analysis finds what appears to be the earliest record of fish testing the land mobility skills of vertebrates, predating by about 10 million years the first evidence of fully terrestrial tetrapod locomotion.
	Transforming the tip of a mechanical pencil lead into a high-quality electron beam source Nanocarbon materials with pointed geometries, such as graphene and carbon nanotubes, are considered promising candidates as sources for field emission electrons. However, their practical application remains limited due to difficulties in controlling the orientation and arrangement of these materials.
	How Zelda and Studio Ghibli inspire happiness and purpose A new study published in JMIR Serious Games reveals that playing the open-world video game The Legend of Zelda: Breath of the Wild and watching Studio Ghibli films can significantly improve young people's overall happiness and sense of purpose in life.
	Room-temperature reactor uses electrochemistry to boost nuclear fusion rates Using a small bench-top reactor, researchers at the University of British Columbia (UBC) have demonstrated that electrochemically loading a solid metal target with deuterium fuel can boost nuclear fusion rates.
	Astronomers capture a record 130-year evolution of a dying star For the first time, scientists have directly tracked the slow transformation of a dying star over more than a century—revealing it is heating up faster than any other typical star ever observed.
