Être « nul en maths » est souvent perçu comme une fatalité ou une conséquence d'un mauvais parcours scolaire. On pointe régulièrement le stress, les mauvaises méthodes pédagogiques ou un environnement peu stimulant. Mais une nouvelle étude publiée dans la revue PLOS Biology vient bouleverser cette vision : l'origine de nos difficultés avec les mathématiques pourrait en réalité se nicher dans la chimie même de notre cerveau.Les chercheurs à l'origine de cette étude se sont penchés sur le rôle des neurotransmetteurs, ces substances qui assurent la communication entre les neurones. En particulier, deux d'entre eux ont été analysés : le glutamate, principal neurotransmetteur excitateur du cerveau, et le GABA (acide gamma-aminobutyrique), qui joue un rôle inhibiteur. Ensemble, ils régulent l'activité cérébrale, un peu comme l'accélérateur et le frein d'un véhicule.En étudiant un groupe d'enfants et d'adolescents à l'aide de techniques d'imagerie cérébrale avancées (spectroscopie par résonance magnétique), les scientifiques ont découvert que l'équilibre entre ces deux neurotransmetteurs dans une région précise du cerveau – le cortex intrapariétal gauche – était directement lié aux compétences mathématiques. Cette zone est connue pour être impliquée dans le traitement numérique et le raisonnement logique.Fait surprenant : le lien entre les niveaux de GABA et de glutamate varie avec l'âge. Chez les plus jeunes, un faible niveau de glutamate est associé à de meilleures performances mathématiques. Mais chez les adolescents plus âgés, c'est un faible niveau de GABA qui semble favoriser les capacités en mathématiques. Cela suggère que la plasticité cérébrale – c'est-à-dire la manière dont le cerveau se reconfigure avec le temps – joue un rôle clé dans la manière dont ces substances influencent notre aisance avec les chiffres.Cette découverte a des implications majeures. Elle montre que nos aptitudes en mathématiques pourraient ne pas être uniquement le fruit d'un bon enseignement ou d'un effort personnel, mais aussi de facteurs biologiques profonds, sur lesquels nous avons peu de contrôle. Cela ne signifie pas pour autant qu'on ne peut pas progresser en maths, mais cela invite à repenser l'approche éducative : certaines personnes pourraient avoir besoin de méthodes plus adaptées à leur fonctionnement cérébral, et non simplement de « travailler plus ».En révélant le rôle du GABA et du glutamate dans la réussite mathématique, cette étude nous pousse à regarder au-delà des notes et des clichés, et à considérer les difficultés scolaires sous un angle plus neuroscientifique – et donc plus humain.

durée : 00:05:22 - Avec sciences - par : Alexandre Morales - Des chercheurs de l'université de Rennes se sont demandé comment parler des failles du système scientifique académique au grand public, sans pour autant le discréditer. Pour ça, ils ont mis en place une opération de communication sous la forme d'une étude, publiée dans la revue Plos Biology.

În cadrul ediției de pe 22 octombrie 2024 a emisiunii Știința360 de pe Radio România Cultural, Dr. Marius Geantă, Președintele Centrului pentru Inovație în Medicină, a comentat ultimele noutăți din domeniul sănătății. Cercetătorii de la Beth Israel Deaconess Medical Center au identificat patru profiluri moleculare distincte ale bolii Alzheimer (AD) folosind o abordare cross-omics. Studiul, publicat în PLOS BIOLOGY, a relevat că unul dintre aceste profiluri este asociat cu o funcție cognitivă mai slabă și caracteristici neuropatologice mai severe. Utilizând tehnici de învățare automată pentru a integra date transcriptomice, proteomice, metabolomice și lipidomice de mare capacitate, această abordare a dezvăluit perspective moleculare noi asupra AD. AD este o tulburare neurodegenerativă complexă, caracterizată de plăci amiloide (Aβ), ghemuri neurofibrilare (NFT), neuroinflamație și pierderea sinaptică și neuronală. Există traiectorii distincte ale patologiei proteinei tau și atrofiei cerebrale, asociate cu multiple caracteristici clinice și patologice ale AD. Cercetătorii au examinat anterior date moleculare provenite din analiza creierului pacienților cu AD și al indivizilor sănătoși, utilizând separat diferite tipuri de analize omice, cum ar fi transcriptomica, proteomica, metabolomica și analiza la nivel de celulă unică. Ei sugerează că, prin combinarea acestor diferite tipuri de date moleculare, pot fi descoperite noi mecansime biologice și schimbări ale căilor moleculare care nu ar fi observate dacă s-ar folosi doar un singur tip de analiză omică. Practic, integrarea mai multor surse de date poate oferi o înțelegere mai completă și mai detaliată a acestei afecțiuni. Mai multe detalii despre subiectele discutate - ▶ Riscul crescut de cancer de sân și ovar, asociat cu mii de mutații ale genei RAD51C ▶ Patru tipuri noi de boală Alzheimer, identificate prin analiză multiomică ▶ Expunerea la radon ar putea crește riscul de leucemie la copii, chiar și la niveluri scăzute ▶ Interzicerea vânzării de tutun la tineri ar putea preveni 1,2 milioane de decese până în 2095

Guest Yani Bellini Saibene Panelist Richard Littauer Show Notes In this episode of Sustain, host Richard welcomes guest Yani Bellini Saibene from Argentina. Yani, with a rich background in open source community management, shares her journey into the tech and open source world, and highlights her roles as the rOpenSci Community Manager, R-Ladies Project Lead, and Vice President for the Board of Directors for The Carpentries. The discussion dives into the challenges of funding, sustainability of volunteer-based models, and the importance of including diverse voices in open source development. The conversation also explores the economic disparities and cultural differences affecting contributors form the global south and how building strong local communities can empower individuals by providing them with tools, knowledge, and a sense of belonging in the wider world. Press download to hear more! [00:01:47] Yani describes her start as a researcher at INTA while at university, her degree in computer science, and her initial work developing software and teaching scientists to use computing tools. She also details her career progression and her master thesis at INTA. [00:04:49] We hear about the foundation and global expansion of R-Ladies, as Yani emphasizes community strength and the organizers' passion. She discusses the flexibility and inclusivity of the chapters, and the support and resources shared among the community. [00:08:56] Richard questions about the distinct roles and activities between rOpenSci, R-Ladies, and The Carpentries, which appear to have similar goals in teaching R, and Yani explains the different objectives of the three organizations. [00:12:50] Yani lists the funders, including the Chan Zuckerberg Initiative, Sloan Foundation, and others. She describes the funding models for R-Ladies and Carpentries and the challenges of sustaining such community-oriented projects. [00:14:52] Richard inquires about the role of the board of directors in establishing post-grant funding. Yani explains The Carpentries' membership model where institutions pay for benefits like workshops and instructor training, she mentions the perks for members, discusses the challenges of maintaining services without sufficient membership or grants, and highlights cultural and financial barriers in Latin America. [00:20:17] Richard is curious about cultural barriers and asks for further insights into overcoming cultural barriers and the limitations of translations. Yani discusses her personal journey with the English language and its importance in coding beyond syntax and shares some data from a recent study that was done, and the paper is called, “The manifold costs of being a non-native English speaker in science,” from PLOS Biology. [00:24:42] Yani discusses additional studies, mentioning the Linux Foundation report on English as a barrier in open source contribution and its influence on perceived expertise. [00:25:55] Richard asks Yani about the point at which translation efforts start to yield benefits for the community and inquires about the visible impacts and dividends from investments in internationalizing materials. Yani cites examples of immediate benefits, and discusses her involvement in translating educational materials, which has supported teaching many Spanish speaking teachers. [00:32:38] Richard raises concerns about the possibility of global exploitation through talent extraction from non-English speaking regions. Yani addresses the issue of local versus international business compensation and the ethical implications for non-profit organizations. [00:36:30] We hear Richard's concerns about how to have conversations about open source contributions and community building in a non-extractive way and he wonders if it's feasible to collectively support open source maintainers financially. Yani explains the concept of three “currencies” in any job: money, heart, and brain. [00:39:16] Yani discusses the champions program at rOpenSci, where stipends were important for participants to allocate time to the tasks and do an excellent job. [00:41:05] Find out where you can follow Yani online. Quotes [00:06:17] “In R-Ladies, you have enough informality and enough expertise to make this a special place to learn.” [00:18:26] “There is little funding for maintaining what you already have.” [00:20:40] “I have to confess that I approached the English language because I loved code.” Spotlight [00:42:26] Richard's spotlight is a book he's reading called, Theodore Rex. [00:43:10] Yani's spotlight is a friend and someone she works with at R-Ladies, Athanasia Mo Mowinckel.

Paul & Dan dig into the buried fossils of original D&D -- like the hidden encounter table for Ice Age adventures in the original boxed set. Where else can you get to use Cave Bears, Woolly Mammoths, and Saber-Toothed Tigers in your fantasy RPG? Pour a cup of hot cocoa and bundle up for this one. In the Late Pleistocene, both marine and continental faunas were essentially modern but with many more large land mammals such as Mammoths, Mastodons, Diprotodons, Smilodons, tigers, lions, Aurochs, short-faced bears, giant sloths, species within Gigantopithecus and others. Isolated landmasses such as Australia, Madagascar, New Zealand and islands in the Pacific saw the evolution of large birds and even reptiles such as the Elephant bird, moa, Haast's eagle, Quinkana, Megalania and Meiolania. The severe climatic changes during the Ice Age had major impacts on the fauna and flora. With each advance of the ice, large areas of the continents became depopulated, and plants and animals retreating southwards in front of the advancing glacier faced tremendous stress. The most severe stress resulted from drastic climatic changes, reduced living space, and curtailed food supply. A major extinction event of large mammals (megafauna), which included mammoths, mastodons, saber-toothed cats, glyptodons, the woolly rhinoceros, various giraffids, such as the Sivatherium; ground sloths, Irish elk, cave lions, cave bears, Gomphotheres, American lions, dire wolves, and short-faced bears, began late in the Pleistocene and continued into the Holocene. Neanderthals also became extinct during this period. At the end of the last ice age, cold-blooded animals, smaller mammals like wood mice, migratory birds, and swifter animals like whitetail deer had replaced the megafauna and migrated north. Late Pleistocene bighorn sheep were more slender and had longer legs than their descendants today. Scientists believe that the change in predator fauna after the late Pleistocene extinctions resulted in a change of body shape as the species adapted for increased power rather than speed.

For a three-year period as a postdoctoral researcher, molecular biologist and visual artist Daniel Jay was given both a lab and a sudio to work in. In the final episode of this six-part Working Scientist about art and science, Julie Gould asks why, decades later, Jay's experience is still unusual. Why do scientists with expertise in, say, music, sculpture, pottery or creative writing have to pursue these interests as weekend hobbies, with science “paying the bills?”Jay, who is Dean of the graduate school of biomedical sciences at Tufts University in Boston, Massachusetts, says today's early career researchers want what he calls a “post disciplinary society,” offering the freedom to pick and choose different areas and competencies.Lou Muglia, a medical geneticist who is now president and CEO of the Burroughs Wellcome Fund, a private foundation located in North Carolina, co-authored a 2023 paper in PloS Biology on art-science collaborations. Muglia says many early career researchers today don't see themselves running a traditional lab, but are as excited about communication and the arts as they are about their science. Many funders now recognise this. Academia should too, he argues.Callie Chappell, Muglia's co-author and a professional artist who researches biosecurity and innovation at Stanford University, California, says: “I would argue that science is actually a type of art. “To do science, you have to be creative, you have to blend different ideas, you have to communicate those ideas by creating something. In many ways that's what artists do.” Each episode in this series concludes with a follow-up sponsored slot from the International Science Council (ISC). The ISC is seeking perspectives from science fiction authors on how science can meet societal challenges, ranging from climate change and food security to the disruption caused by artificial intelligence.

We discuss the need for marine eco policies and "sustainable fishing" policies to move toward a non-industrial discourse that treats fish as subjects and as ecological beings rather than primarily objectifying them as human food/stock/seafood – basically sustainable fisheries rhetoric should stop reducing fish and other aquatic animal species to mere economic resources to be 'sustainably managed'. Dr. Jennifer Jacquet, Professor of Environmental Science and Policy at Univ of Miami, explains her rationales for why a change in our discussion of fish (and relationship with fish) is warranted and ecologically beneficial, in this 25-minute podcast with host Carrie Freeman.  This is based on an provocative perspective piece that Dr. Jennifer Jacquet recently co-authored with Dr. Daniel Pauly, published in the journal PLOS Biology, titled "Reimagining Sustainable Fisheries" that challenges the bias toward industrial fishing and economic commodities in our fisheries and marine environmental policies. She also unpacks the excuse that we need managed industrial fishing with quotas to "feed people" or for "food security" when so much caught fish just goes to feed farmed animals (including farmed fish) and to feed wealthier consumer market demands when these consumers often have more sustainable food options (like plant-based). She explains why sustainable fisheries policies need to focus on subsistence fishing (not industrial) and especially protecting marine habitats to help aquatic animals begin to thrive free of harassment/harm. The move to reimagine whales as beings not commodities can be a model for cultural and political change toward other marine animals.

In this 186th in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we discuss the state of the world through an evolutionary lens. In this episode we discuss the mechanism of action by which the mRNA vaccines cause heart damage, following the publication of relevant research in Science Immunology. We discuss the nature of science, both empirical and theoretical, and why the eclipsing of theoretical science by the empiricists is dangerous. We discuss how fields become stuck, and why, once they get stuck, it is easy to best them. We discuss a new paper that describes two case studies of teenage males who have recurring myocarditis post mRNA vaccine. And we talk about social learning in bumblebees: they learn how to solve puzzles from others of their own kind. As do we. ***** Our sponsors: UnCruise: Get $500 off any adventure cruise on a small ship into destinations including Galapagos, Panama, Alaska, and the San Juan Islands: https://uncruise.com/pages/darkhorse/ American Hartford Gold: Get up to $5,000 of free silver on your first qualifying order.

Why Are Children's Antibiotics So Hard To Find Right Now? Mary Warlo has been extremely worried lately. Her baby Calieb, who is six months old, has sickle cell disease. In early December he went for a few days without liquid penicillin, a medication that he—and thousands of other children in the U.S.—rely on to prevent potentially life threatening infections. Warlo couldn't easily find a pharmacy in Indianapolis that had the medicine in stock. She and her husband frantically drove around for hours, stopping at five different pharmacies before they were able to get their prescription filled. “It was extremely stressful and I am worried about what will happen the next time we need to fill his prescription two weeks from now,” she said. Pediatric sickle cell disease specialists say they are alarmed by signs that the stock of liquid penicillin is dwindling in some places. They say children's lives depend on this medication, and a penicillin shortage could spell disaster. Read the rest at sciencefriday.com.   Bats Use Death Metal 'Growls' To Make Social Calls What do death metal vocalists and bats have in common? Both use their ventricle folds, or “false vocal cords,” to extend their vocal ranges to hit a lower register. This gives bats a huge vocal range—seven full octaves. Humans typically tap out at about three to four octaves. Even people with really impressive vocal ranges, like Mariah Carey, just can't compete with a bat. A study recently published in the academic journal PLOS Biology examines how and why different anatomical structures might help bats achieve such extreme frequency range. Ira talks with one of the study's authors, Coen Elemans, a professor in bioacoustics and animal behavior at the University of Southern Denmark based in Odense, Denmark.   Can Science Answer Life's Biggest Questions? Dr. Alan Lightman has been around the block a few times. Over the past five decades, he has been a theoretical physicist, professor at MIT, and bestselling author—often at the same time. His most notable novel, Einstein's Dreams, has been adapted into dozens of plays and musicals since its publication in 1992, becoming one of the most famous examples of mixing art and science.  Lightman's work follows a philosophical way of thinking about life's biggest questions, like the origins of consciousness. His new venture brings this way of thinking to the silver screen. Searching: Our Quest for Meaning in the Age of Science consults scientists and faith leaders to grapple with some of these theoretical quandaries. And Lightman gives a good argument for why the journey to these answers can be more impactful than the answers themselves.  Ira speaks with Alan Lightman about the new program, available to watch now online and on your local public television station.

I think the growing appreciation that the world that surrounds us is full of sophisticated and unique minds places on us a kind of onus and obligation to preserve the diversity of these minds that are out there and make sure that they continue to thrive."Lars Chittka is professor of sensory and behavioral ecology at Queen Mary University of London, where he founded a new Research Centre for Psychology in 2008 and was its scientific director until 2012.

La puntata 413 si apre con Andrea che ci parla della recente misura diretta della massa di alcuni quark pesanti, effettuata al CERN dall'esperimento ALICE, sfruttando una tecnica nuova, detta del "dead cone". La notizia è apparsa su Nature poche settimane fa. Giuliana ha intervistato Andrea Vico, giornalista che da oltre 30 anni si occupa di scienza e ambiente, che ci parla del suo ultimo libro "La notte delle tartarughe", edito da Emons. Julien ci racconta infine di una ricerca pubblicata su PLOS Biology, che correla l'interessamento alla salvaguardia delle specie ittiche al loro aspetto. La cosa è per certi versi spiazzante, ma non è la prima volta che si osserva un comportamento degli umani verso gli animali fortemente influenzato dall'empatia che ci fanno provare.

News: Scientists Say New Treatment Lets Alopecia Patients Regrow Hair | Futurism (01:14) Scientists at Yale announced this week that a common arthritis medication (baricitinib) appears to help alopecia patients regrow their hair. a potential treatment for a widespread autoimmune condition. Baricitinib is used to reduce pain, stiffness, and swelling in adults with rheumatoid arthritis after other treatments have failed. Helps slow the progression of bone and joint damage. It is a Janus kinase (JAK) inhibitor  Janus kinase (JAK) inhibitors are a group of medications that inhibit activity and response of one or more of the Janus kinase enzymes (JAK1, JAK2, JAK3, and TYK2). These enzymes normally promote inflammation and autoimmunity. Alopecia is a common autoimmune disorder that causes hair loss Affects people of all ages, although it most commonly appears in adolescence or early adulthood.  Affects 1 in every 500 to 1,000 people in the United States. There is currently no FDA-approved treatment for the disease. Dr. Brett King, lead author on the study told Yale news:“This is so exciting, because the data clearly show how effective baricitinib is … These large, controlled trials tell us that we can alleviate some of the suffering from this awful disease.” For the study, the researchers conducted two large, randomized trials involving a total of 1,200 people. For 36 weeks, participants were given a daily dose of either 4 milligrams of baricitinib, 2 milligrams of baricitinib, or a placebo. One-third of the patients who received the larger dose grew hair back. The researchers stated that baricitinib thwarts the disease by disrupting the communication of immune cells involved in harming hair follicles.  Hopefully this medication will be proven to be safe & effective and approved by regulators.   Waymo says fully driverless rides are coming to San Francisco | The Verge (06:47) Waymo plans to start offering rides in its fully autonomous vehicles — without human safety drivers behind the wheel — in San Francisco.  They join a waitlist and, once approved, sign non-disclosure agreements to get access to the company's early technology. As of right now it is only available to employees but will soon grow to include members of the company's “Trusted Tester” program. The Trusted Tester program is for customers interested in using Waymo's robotaxis.  The vehicles will be available 24 hours a day, seven days a week, Waymo says. Additionally, Waymo is making moves in Arizona.Growing to include downtown Phoenix after operating exclusively in the exurban towns of Chandler, Gilbert, Mesa, and Tempe for nearly five years. Waymo has been running fully driverless rides without a safety driver in those towns outside of Phoenix for more than a year now.  They must be confident they have enough data to move forward with autonomous taxis.Last year, the company logged the most miles driven autonomously of all the companies permitted to test in the state: 2.3 million miles, a huge increase over 2020, when it had about 629,000 miles driven, and even the pre-pandemic year of 2019, with 1.45 million. The expansion of Waymo's service area in Phoenix and the imminent launch of driverless rides in San Francisco signal the company's sense of confidence that its vehicles can operate safely and efficiently in more dense, urban environments.    Quantum technology could make charging electric cars as fast as pumping gas | Phys.org (12:10) For a long time, batteries had far lower energy density than those offered by hydrocarbons, which resulted in very low ranges of early electric vehicles.Improvements in battery technologies eventually allowed the drive ranges of electric cars to be within acceptable levels However, despite the vast improvements in battery technology, today's consumers of electric vehicles face another difficulty: slow battery charging speed.Takes about 10 hours to fully recharge at home Even the fastest superchargers require up to 20 to 40 minutes to fully recharge This creates additional costs and inconvenience to the customers. To address this problem, scientists looked for answers in the field of quantum physics.Which led to a discovery that quantum technologies may promise new mechanisms to charge batteries at a faster rate.  It was theorized that quantum resources, such as entanglement, can be used to vastly speed up the battery charging process by charging all cells within the battery simultaneously in a collective manner. Conventional batteries collective charging is not possible, where the cells are charged in parallel independently of one another.  In this most recent study, researchers were able to precisely quantify how much charging speed can be achieved with this collective charging scheme vs parallel. The charging speed increases linearly with the number of cells in classical batteries. The study showed, however, that quantum batteries employing global operation can achieve quadratic scaling in charging speed. To illustrate this, consider a typical electric vehicle with a battery that contains about 200 cells. Charging time at home would be cut from 10 hours to about 3 minutes. Quantum charging would lead to a 200 times speedup over classical batteries,  High-speed charging stations, the charge time would be cut from 30 minutes to mere seconds. Of course, quantum technologies are still in their infancy and there is a long way to go before these methods can be implemented in practice. However, this study creates a promising direction and can incentivize the funding agencies and businesses to further invest in these technologies.   HB11's hydrogen-boron laser fusion test yields groundbreaking results | New Atlas (18:24) Australian company HB11 is approaching nuclear fusion from an entirely new angle, using high power, high precision lasers instead of hundred-million-degree temperatures to start the reaction.The 1st demo ​​produced 10 times more fusion reactions than expected The company started tooting their own horn: “the only commercial entity to achieve fusion so far [making it] the global frontrunner in the race to commercialize the holy grail of clean energy." Just to summarize quickly what is required for fusion: Like throwing powerful magnets at each other in space Most companies try to replicate this by magnetically confining hydrogen atoms in a plasma In order to smash atoms together hard enough to make them fuse together and form a new element, you need to overcome the incredibly strong repulsive forces that push two positively-charged nuclei apart.  The Sun accomplishes this by having a huge amount of hydrogen atoms packed into a plasma that's superheated to tens of millions of degrees at its core. HB11 is using a different approach that doesn't require huge amounts of heat, or tricky, radioactive fuels like tritium.Takes advantage of recent advances in ultra-high powered "chirped pulse amplification" lasers that can produce monstrous, unprecedented power levels over 10 petawatts. An HB11 reactor would be a mostly empty metal sphere, with a "modestly sized" boron fuel pellet held in the middle, and apertures in two spots on the sphere for a pair of lasers. One laser, in combination with a capacitive coil, is used to establish a powerful kilotesla magnetic containment field for the plasma. The second is used to massively accelerate hydrogen atoms through the boron sample. The reactor is not heating things up in the hope that they'll smack together at speed.It is aiming the hydrogen right at the boron and using these bleeding-edge lasers to make it go so fast that it'll fuse if it hits a nucleus. Hydrogen-boron fusion doesn't create heat, it merely creates "naked" positively charged helium atoms, or alpha particles They collect that charge to create energy, rather than needing to superheat steam and drive turbines. Initial experiments on laser-triggered chain reactions returned reaction rates a billion times higher than anticipated, and then seem pretty happy about it and a little cocky:“This is many orders of magnitude higher than those reported by any other fusion company, most of which have not generated any reaction despite billions of dollars invested in the field. The results show great potential for clean energy generation: hydrogen-boron reactions use fuels that are safe and abundant, don't create neutrons in the primary reaction so cause insignificant amounts of short-lived waste, and can provide large-scale power for base-load grid electricity or hydrogen generation." Mitochondrial transplants between living cells could save dying organs | ETH News (23:53) In a technological breakthrough, researchers at ETH Zurich have announced the development of a new technique that can transplant mitochondria.Mitochondria are the tiny powerhouses of the cell where the processes of cellular respiration take place In their research, recently published in the journal PLOS Biology, the group successfully used a ‘nanosyringe' they had previously developed to transplant mitochondria from one living cell to another. In more detail:These cylindrical nanosyringes were specially developed for this study, the researchers pierced the cell membrane and sucked up the spherical mitochondria. They then pierced the membrane of a different cell and pumped the mitochondria back out of the nanosyringe into the recipient cell. The position of the nanosyringe is controlled by laser light from a converted atomic force microscope. A pressure regulator adjusts the flow, allowing scientists to transfer incredibly small volumes of fluid in the femtoliter range (millionths of a millionth of a milliliter) during organelle transplants The transplanted mitochondria have a high survival rate – more than 80 percent. The injected mitochondria begin to fuse with the filamentous network of the new cell 20 minutes after transplantation. The technique could be deployed as a way of treating diseased organs, but may also find use in the realm of anti-aging, rejuvenating stem cells that deteriorate in metabolic activity as we grow older.
