Más píxeles de los que ves: Pantallas 8K y 4K prometen imágenes más nítidas, pero un estudio demuestra que tus ojos no las distinguen.  Por Félix Riaño @LocutorCo  Investigadores de Cambridge y Meta descubrieron que el ojo humano tiene un límite real para detectar detalles en pantallas. Más allá de cierto punto, los televisores Ultra HD no se ven mejor, aunque cuesten miles de dólares.  Sigue el pódcast Flash Diario para descubrir más curiosidades de ciencia y tecnología.  Científicos de la Universidad de Cambridge y del laboratorio de realidad de Meta analizaron cuántos píxeles puede distinguir el ojo humano en distintas condiciones. Su conclusión es clara: en un salón promedio, una pantalla 4K o 8K no ofrece una diferencia visible frente a una 2K. El estudio, publicado en Nature Communications, demuestra que los límites de nuestra visión convierten muchos televisores de alta gama en un gasto innecesario. A partir de ahora, la ciencia tiene una medida precisa para responder una pregunta que millones de personas se han hecho frente a una vitrina: ¿realmente se ve mejor un televisor más caro?  Más píxeles no siempre significan mejor imagen, solo más gasto.  Durante años, las marcas de televisión han competido por ofrecer resoluciones más altas: primero Full HD, luego 4K, después 8K. Cada salto prometía una experiencia visual “más real”. Pero un equipo de Cambridge y Meta quiso poner esa promesa a prueba. Construyeron un experimento con un monitor 4K de 27 pulgadas montado en un riel móvil. Dieciocho personas con visión normal observaron líneas finas en distintos colores y distancias. Cuando las líneas eran demasiado pequeñas, los voluntarios ya no podían distinguirlas: veían solo una mancha gris. Con esa información, los científicos calcularon la capacidad real del ojo humano para detectar píxeles individuales.  El resultado fue sorprendente. La mayoría de las personas puede distinguir hasta 94 píxeles por grado en escala de grises, y unos 89 cuando se trata de colores rojo y verde. En cambio, los tonos amarillo y violeta caen hasta 53 píxeles por grado, porque nuestro cerebro procesa peor los detalles de color que los de luz y sombra. Esa limitación biológica significa que, si tienes una televisión de 44 pulgadas y la ves a unos 2,5 metros de distancia —como en la mayoría de salas—, ya estás recibiendo más detalle del que tu vista puede procesar. En otras palabras: comprar una tele 8K no hace que veas mejor, solo hace que pagues más.  Los científicos publicaron una tabla y una calculadora en línea que permiten saber si un televisor realmente ofrece mejoras visibles según el tamaño y la distancia de visualización.Aquí tienes el enlace a la calculadora en línea de la University of Cambridge:Display resolution calculatorPor ejemplo, una pantalla de 40 pulgadas vista a 3 metros se aprovecha totalmente en resolución Full HD. Para notar la diferencia con 4K, habría que acercarse mucho o tener un televisor gigante. Incluso para que una pantalla 8K valga la pena, necesitarías una de 100 pulgadas y verla desde menos de 2 metros. Además, cada píxel adicional consume más energía, requiere más potencia de procesamiento y eleva el precio sin ofrecer beneficios visuales.  El estudio también tiene implicaciones fuera del salón de casa. En la realidad virtual, los videojuegos y los móviles, muchas empresas invierten en pantallas con densidades imposibles de distinguir. Cambridge y Meta advierten que ese esfuerzo podría redirigirse a mejoras más perceptibles, como el contraste, el color o la velocidad de respuesta. El hallazgo pone en duda prácticas comunes como la “submuestra de color”, usada para ahorrar ancho de banda al reducir la resolución de los tonos. El estudio demuestra que el ojo distingue más matices rojo-verde de lo que se creía, lo que podría transformar la forma de comprimir video en el futuro. En resumen, no es que las pantallas 8K sean malas, es que nuestros ojos ya llegaron a su límite.  La ciencia confirma que el ojo humano tiene un límite de detalle. Si ves tu tele desde el sofá, 4K ya es más de lo que puedes distinguir. Antes de gastar en 8K, consulta la calculadora de Cambridge y revisa si realmente lo necesitas.Científicos de Cambridge descubren que el ojo humano no nota diferencia entre 2K, 4K y 8K en tu sala de casa.

Dr Nikolay Kukushkin on Memory

What if your body is learning things your mind doesn't know? What if memory wasn't just something that our brain has?Episode Summary On this episode, I'm exploring a bold idea with neuroscientist Dr Nikolay Kukushkin: memory doesn't just live in the brain. It might be a basic property of life itself. We unpack how scientists define memory (behavioural change over time) versus how the rest of us use the word, and why that distinction matters—from sea slugs to kidney cells. I ask the “muscle memory” question we all carry, and we separate the metaphor from the biology: your basal ganglia automate behaviours, but your muscle cells do literally adapt to patterned use.We go deep on “patterns.” Nikolay's work shows that even non-neural cells can detect minute-scale timing differences—preferring spaced pulses over a single crammed dose. That has huge implications for learning, exercise, nutrition, and even medicine; it suggests timing might be as important as quantity. We also talk about sleep as essential “synaptic housekeeping,” why false memories are an adaptive feature (not a failure), and what it really means to “run out of memory” in our overstimulated world.Finally, we tilt at the big questions: how consciousness might have evolved, why Plato's model of perception eerily echoes today's top-down/bottom-up neuroscience, and what AI still lacks—learning patterns in time within an embodied world. If you've ever crammed for an exam, worried about forgetting your own name, or wondered what your cells are quietly learning from your daily routines, this one will rewire how you think about memory.Guest Biography — Dr Nikolay KukushkinDr Nikolay Kukushkin is a Clinical Associate Professor at NYU. His book One Hand Clapping: Unraveling the Mystery of the Human Mind  traces how consciousness emerged from the natural world; the original Russian edition won the Enlightener (Prosvetitel) Award and the Alexander Belyaev Medal.His recent research (Nature Communications, Nov 2024) showed that non-neural human cells display the classic “spacing effect,” suggesting memory-like temporal patterning beyond the brain.AI-Generated Timestamped Summary [00:00:00] Cold open: reframing memory as cellular, not just neural. [00:01:00] Scientists' definition of memory vs everyday usage. [00:03:00] From behaviour change to cellular change; beyond “plugging a muscle into a brain.” [00:05:00] All cells have experiences; “pattern matters.” [00:06:00] Muscle memory: basal ganglia automation vs literal muscle adaptation. [00:07:00] Shared molecular machinery: “use it or lose it” in brain and muscle. [00:08:00] Nikolay's path: from molecules to minds; bottom-up neuroscience. [00:09:00] Protein quality control: molecular barcodes and cellular “conversations.” [00:11:00] Why sea slugs: short path from molecules to behaviour. [00:13:00] Hypothesis leap: if single neurons learn from pulses, could kidney cells? [00:14:00] The experiment: four 3-min pulses vs one 12-min pulse (spacing wins). [00:16:00] What's uniquely neural: synapses and specific connectivity; where salience arises. [00:19:00] Memory without awareness; non-neural systems can store patterns. [00:20:00] Applications: exercise, diet, medicine; timing as a lever. [00:23:00] The dark mirror: life as obsessive optimisation if we over-pattern. [00:24:00] Personal practice: being mindful of inputs, attention as filter. [00:26:00] Debunking “10% of the brain” and the sleep–memory link. [00:28:00] Sleep weakens synapses; deprivation leads to saturation and hallucinations. [00:30:00] The social-media “soup” analogy for saturated memory. [00:32:00] Names, identity and rehearsal; de-naming as degradation. [00:33:00] Reconsolidation: why false memories are a feature we need. [00:34:00] 9/11/Challenger studies: how memories drift with time. [00:36:00] Ebbinghaus and the spacing effect across species and systems. [00:39:00] Cramming vs spacing: initial strength and decay rates. [00:41:00] The forgetting curve and why “more” can decay slower in memory. [00:42:00] “My whole life is one big experiment on my brain.” [00:43:00] Practical “tip”: fix attention first; follow interest, not force. [00:45:00] Attention economy and selective inputs as memory hygiene. [00:48:00] From smoking to scrolling: a future of information hygiene. [00:50:00] One Hand Clapping: why it feels special to be you. [00:54:00] Plato's “two fires”: ancient echoes of top-down/bottom-up perception. [00:58:00] Intuition as hidden associations; LLMs as an analogy. [01:00:00] AI: excitement, unease, and the risk of outsourcing humanness. [01:03:00] What AI lacks: learning patterns in time without a body. [01:05:00] Close and thanks.

El análisis de ADN antiguo ha revelado la existencia de un linaje autóctono que habitó la península durante más de veinte mil años, convivió con los primeros caballos domesticados y desapareció coincidiendo con las Guerras Púnicas, en un periodo de grandes movilizaciones entre África, Iberia e Italia. Los restos del yacimiento tartésico de Casas del Turuñuelo, en Guareña (Badajoz), han sido fundamentales para esclarecer este capítulo perdido de la historia equina.

In this episode of SpaceTime, we uncover the latest findings in Martian meteorology, delve into Earth's ancient tectonic activity, and prepare for humanity's return to the Moon.Raging Winds on Mars: Unveiling Martian Weather PatternsA groundbreaking study published in the journal Science Advances reveals that wind speeds on Mars can reach up to 160 km/h, significantly higher than earlier estimates. Lead author Valentin U.H. Meckel from the University of Bern discusses how these powerful winds, along with dust devils, play a crucial role in shaping Mars' climate and dust distribution. This episode explores how the observations from the European Space Agency's Mars Express and ExoMars Trace Gas Orbiter have provided unprecedented insights into Martian atmospheric dynamics, which are essential for planning future manned missions to the Red Planet.Unlocking Earth's Deep Past: New Insights into SubductionIn a surprising twist to our understanding of early Earth, a new study published in Nature Communications suggests that subduction and continental crust formation occurred much earlier than previously believed. Researchers utilized advanced geochemical analysis of ancient olivine crystals to challenge the notion of a stagnant lid tectonic regime during the Hadean eon. This episode discusses the implications of these findings on our understanding of Earth's geological history and the processes that shaped our planet's surface.NASA's Artemis II: Preparing for Lunar ExplorationNASA is set to send astronauts back to the Moon with the Artemis II mission, slated for launch in early 2026. This episode provides an overview of the mission's objectives, including a ten-day crewed flyby of the Moon, which will test the Orion spacecraft and gather crucial scientific data.

Nella puntata 582 esploriamo tre modi diversi di indagare la mente e la realtà: dalla creatività che mantiene giovane il cervello, al sonno che regola emozioni e memoria, fino alle misurazioni quantistiche che sfidano i limiti stessi della conoscenza.Ilaria ci racconta come un recente studio pubblicato su Nature Communications ha dimostrato che diverse attività creative come suonare, ballare o dipingere possano mantenere il cervello giovane. I ricercatori hanno utilizzato particolari “orologi cerebrali” per stimare l'età biologica del cervello e hanno osservato che, in alcune persone creative, esso risulta fino a sette anni più giovane rispetto all'età anagrafica.Le analisi hanno evidenziato come chi si dedica regolarmente a esperienze artistiche o cognitive — dal tango ai videogiochi strategici — presenti una rete di connessioni neuronali più efficiente. Vi state tutti già iscrivendo ad un corso di tango? Per approfondire: https://neurosynth.org/Nell'esterna di questa settimana Anna intervista il Dr. Mattia Aime, Professore e neuroscienziato all' Università di Berna in Svizzera. Mattia studia uno dei fenomeni cognitivi più affascinanti: il sonno. E la sua ricerca sta portando alla luce quanto il sonno sia importante non solo per le nostre capacità cognitive ma anche per le capacità di regolare le nostre emozioni. Ne vogliamo parlare perché' nella nostra società il sonno spesso viene visto come qualcosa di superfluo che ci fa perdere tempo riducendo la nostra performance. Tanto che abbiamo addirittura dei proverbi a riguardo e nell'intervista cominciamo proprio da uno di questi: sarà vero che ci dorme non piglia pesci?Andrea infine ci ricorda che ogni progresso scientifico si basa su misure sempre più precise, e che la meccanica quantistica, pur offrendo strumenti straordinari per migliorare la precisione, impone anche dei limiti, per esempio il principio di indeterminazione di Heisenberg, secondo cui non si possono conoscere contemporaneamente con accuratezza assoluta grandezze come posizione e quantità di moto.Un recente studio ha però mostrato come sia possibile aggirare questo vincolo misurando invece osservabili modulari, grandezze “compatibili” che rappresentano una sorta di versione quantistica complementare di quelle normalmente incompatibili.I ricercatori hanno realizzato questo tipo di misura utilizzando gli stati a griglia del moto meccanico di uno ione intrappolato, ottenendo incertezze inferiori al limite quantico standard. Hanno inoltre esteso l'approccio a un'altra coppia di osservabili, numero e fase, dimostrando un vantaggio metrologico rispetto ai limiti classici.Diventa un supporter di questo podcast: https://www.spreaker.com/podcast/scientificast-la-scienza-come-non-l-hai-mai-sentita--1762253/support.

With the shutdown, you can forget about getting jobs or inflation data for now (except from payroll firm ADP, which says companies shed 32,000 jobs in September—so, yeah, not great). Meanwhile, the Supreme Court told Trump he can't just boot Fed Governor Lisa Cook on the spot, kicking that fight to January.

Before the written word — and possibly even before speech — humans have communicated through drawing. From crude scratches in the dirt or on cave walls to the arcane symbology of the laboratory whiteboard, our instinct for conveying our thoughts visually is pretty extraordinary. We see or understand something in the world, we build an idea in our mind of what we think we see, and then using our hand and the utensil we re-create it to communicate the share our perception with others. Along the way, we add in our own understanding and experience to craft that communication in ways that might not correspond with a specific object in the world at all.How we do this — and how we can learn to be better visual communicators — is at the heart of our conversation with Judy Fan, who runs the Cognitive Tools Lab in Stanford University's Department of Psychology.We've been nominated for a 2025 Signal Award for Best Science & Education Podcast!

Imaginez un duo de jumeaux de plus de soixante ans. Même patrimoine génétique, parcours de vie souvent proches, habitudes semblables. Et pourtant, après douze semaines d'un simple ajout à leur alimentation, l'un d'eux se souvient mieux, apprend plus vite, tandis que l'autre ne constate aucun changement. Quelle est la différence ? Des prébiotiques, ces fibres alimentaires qui nourrissent les bonnes bactéries de notre intestin.Cette scène n'est pas une fiction mais le cœur d'une étude publiée début 2024 dans Nature Communications. Des chercheurs britanniques ont recruté 36 paires de jumeaux âgés en moyenne de 73 ans. Tous ont suivi un programme d'exercices et reçu des acides aminés bénéfiques pour la musculature. Mais un seul des deux jumeaux de chaque paire recevait, en plus, un supplément quotidien de prébiotiques. Trois mois plus tard, les résultats sont frappants : ceux qui avaient nourri leur microbiote intestinal obtenaient de meilleurs scores dans des tests de mémoire visuelle et d'apprentissage. Notamment, ils faisaient moins d'erreurs dans un exercice consistant à mémoriser des associations entre des images et des emplacements, un test considéré comme sensible aux premiers signes du déclin cognitif.Comment expliquer ce lien étonnant entre intestin et mémoire ? Tout passe par ce que les scientifiques appellent l'axe microbiote-intestin-cerveau. Les milliards de bactéries logées dans nos intestins produisent en permanence des molécules, comme des acides gras à chaîne courte ou même certains neurotransmetteurs, capables de circuler dans le sang et d'agir sur le cerveau. En modulant l'inflammation, en influençant la chimie cérébrale et même en dialoguant via le nerf vague, le microbiote peut contribuer à protéger ou à fragiliser nos capacités cognitives.Dans cette expérience, les prébiotiques ont favorisé la croissance de bifidobactéries, connues pour leurs effets bénéfiques. Et cette transformation interne s'est traduite par un petit coup de pouce mental. Certes, l'effet n'est pas spectaculaire, et il reste limité à une courte période et un petit échantillon. Mais il s'agit d'une preuve élégante, renforcée par le choix de jumeaux, que nourrir son intestin peut aussi nourrir sa mémoire.Ce résultat ouvre des perspectives intrigantes : et si, avec l'âge, un simple ajustement alimentaire suffisait à retarder le déclin cognitif ? Et si la clé pour protéger notre mémoire se trouvait dans notre assiette, dans ces fibres oubliées qui, silencieusement, font travailler pour nous des milliards de microbes alliés ? La recherche continue, mais une chose est sûre : notre intestin a bien plus à dire à notre cerveau que nous ne l'imaginions. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

Dust from car tires can be bad for fish — what might it do to us?As car tires wear, they shed billions of ultrafine particles of rubber that contain a complex mix of chemicals, including one called 6PPD-Quinone that's been linked to mass die-offs of migrating salmon. Now researchers are sounding the alarm that this chemical is accumulating in humans, and we have no clear understanding of its toxicity. An international team of scientists, including Rachel Scholes from the University of British Columbia, are calling for more scrutiny of the chemicals that go into car tires, since so much ends up in our environment. Their paper was published in the journal Environmental Science & Technology Letters.Fecal Transplants seem to have lasting metabolic effectsTransplanting the gut microbiome has been held out as a hope for a range of disorders, from obesity to mental health issues. A study that followed obese adolescents four years after receiving a fecal microbiota transplant from healthy individuals has shown positive impacts on the recipients' weight and metabolic health. Dr. Wayne Cutfield, a pediatrician and professor of pediatric endocrinology at the University of Auckland in New Zealand, said they also found after all this time that the donor bacteria have remained established in the recipients' gut microbiome. The study is in the journal Nature Communications. An ant queen clones sexual slaves of another species for her daughtersIn a truly bizarre tale from the animal world, researchers have discovered a species of ant where the queen gives birth to males of two totally different species. Somewhere along their evolutionary path, these Messor ibericus queen ants in southern Europe developed an ability to clone male Messor structor ants for her daughters to mate with and to produce a hybrid working class. Jonathan Romiguier, an evolutionary biologist from the University of Montpellier in France, said these M. ibericus ants essentially domesticated ants of another species. The study was published in the journal Nature. Why other apes can't walk a mile in our shoesA feature that distinguishes humans from other primates is the ability to walk upright. The major evolutionary change in the structure of our pelvis that allows for our bipedalism has now been traced genetically and developmentally. Human pelvic blades initially form in the embryo like other primates, but then flip their growth from vertical to horizontal, to give the human pelvis its unique basin shape. This new research led by Terence Capellini, Chair of the human evolutionary biology department at Harvard University and postdoctoral student Gayani Senevirathne, was published in the journal Nature.Women glow. So do men. Understanding our 'inner light'You might have been told by an admirer that you have a unique glow. In two groundbreaking studies, researchers have demonstrated the reality of that poetic compliment. Using ultra-sensitive instruments capable of detecting individual photons, Canadian researchers have imaged a biological source of incredibly faint light, known as Ultraweak Photon Emissions (UPE), that has potential as a future non-invasive diagnostic imaging tool. Daniel Oblak, an associate professor of physics and astronomy at the University of Calgary, oversaw a study where they unequivocally demonstrated that living things, like mice, give off an extremely faint glow that dims when they die. His study was published in The Journal of Physical Chemistry Letters. In a separate study, Nirosha Murugan, — an assistant professor of tissue biophysics at Wilfred Laurier University — discovered that these UPEs can also detect different mental states in the brain. That study was published in the journal iScience.

Quantum sensitivity breakthrough with Eli Levenson-Falk

Dr. Eli Levenson-Falk joins Sebastian Hassinger, host of The New Quantum Era to discuss his group's recent advances in quantum measurement and control, focusing on a new protocol that enables measurements more sensitive than the Ramsey limit. Published in Nature Communications in April 2025, this work demonstrates a coherence stabilized technique that not only enhances sensitivity for quantum sensing but also promises improvements in calibration speed and robustness for superconducting quantum devices and other platforms. The conversation travels from Eli's origins in physics, through the conceptual challenges of decoherence, to experimental storytelling, and highlights the collaborative foundation underpinning this breakthrough.Guest BioEli Levenson-Falk is an Associate Professor at USC. He earned his PhD at UC Berkeley with Professor Irfan Siddiqui, and now leads an experimental physics research group working with superconducting devices for quantum information science. Key TopicsThe new protocol described in the paper: “Beating the Ramsey Limit on Sensing with Deterministic Qubit Control." Beyond the Ramsey measurement: How the team's technique stabilizes part of the quantum state for enhanced sensitivity—especially for energy level splittings—using continuous, slowly varying microwave control, applicable beyond just superconducting platforms. From playground swings to qubits: Eli explains how the physics of a playground swing inspired his passion for the field and lead to his understanding of the transmon qubit, and why analogies matter for intuition. Quantum decoherence and stabilization: How the method controls the “vector” of a quantum state on the Bloch sphere, dumping decoherence into directions that can be tracked or stabilized, markedly increasing measurement fidelity. Calibration and practical speedup: The protocol achieves greater measurement accuracy in less time or greater accuracy for a given time investment. This has implications for both calibration routines in quantum computers and for direct quantum measurements of fields (e.g., magnetic) or material properties. Applicability: While demonstrated on superconducting transmons, the protocol's generality means it may bring improved sensitivity to a variety of platforms—though the greatest benefits will be seen where relaxation processes dominate decoherence over dephasing. Collaboration and credit: The protocol was the product of a collaborative effort with theorist Daniel Lidar and his group, also at USC. In Eli's group, Malida Hecht conducted the experiment.Why It MattersBy breaking through the Ramsey sensitivity limit, this work provides a new tool for both quantum device calibration and quantum sensing. It allows for more accurate and faster frequency calibration within quantum processors, as well as finer detection of small environmental changes—a dual-use development crucial for both scalable quantum computing and sensitive quantum detection technologies.Episode Highlights Explanation of the “Ramsey limit” in quantum measurement and why surpassing it is significant. Visualization of quantum states using the Bloch sphere, and the importance of stabilizing the equatorial (phase) components for sensitivity. Experimental journey from “plumber” lab work to analytic insights, showing the back-and-forth of theory confronting experiment. Immediate and future impacts, from more efficient calibration in quantum computers to potentially new standards for quantum sensing. Discussion of related and ongoing work, such as improvements to deterministic benchmarking for gate calibration, and the broader applicability to various quantum platforms.If you enjoy The New Quantum Era, subscribe and tell your quantum-curious friends!

In this episode of the Epigenetics Podcast, we talked with Emily Wong from the University of New South Wales in Sydney about her work on how evolution shapes mammalian genes. As the head of the Regulatory Systems Lab at the Victor Chang Cardiac Research Institute and an associate professor at UNSW, Emily's research centers on gene control and enhancers. We delve into her pivotal 2017 publication in Nature Communications, where she investigated transcription factor binding in liver-specific contexts, shedding light on the regulatory mechanisms at play in mammals. Emily elaborates on her postdoctoral work at the European Bioinformatics Institute and the innovative hybrid systems she used to dissect genetic variation effects, which allowed her to differentiate between cis-regulatory and trans-regulatory influences. By employing techniques like ChIP-seq, she was able to illustrate the combinatorial effects of transcription factors on gene expression, paving the way for her collaborative efforts across disciplines and organisms. We also examine Emily's findings regarding enhancer function through comparative studies between zebrafish and marine sponges. Using historical data on conserved genetic sequences, she and her team identified enhancer regions that displayed activity in specific vertebrate cell types, despite their evolutionary divergence from sponges. This unexpected result suggests deeper insights into how enhancers can be co-opted for new functions as species evolve. Furthermore, we dive into Emily's latest ventures involving advanced methodologies such as chromatin accessibility profiling with ATAC-seq and how these insights can elucidate the genomic landscape of metazoan embryogenesis. She highlights significant correlations between enhancer turnover and DNA replication timing, suggesting evolutionary implications that should be taken into account in future genomic studies.   References Wong, E.

What if medicine worked to get you healthier overall—not just people like you or for one or another symptom? In the latest episode of TGen Talks, host Karie Dozer sits down with Nicholas Schork, Ph.D., and Laura Goetz, M.D., co-authors of a recent commentary published in Nature Communications, From Precision Interventions to Precision Health, to explore the promise—and complexity—of truly personalized healthcare. Traditional medicine treats symptoms. Precision healthcare, however, rethinks that model entirely. By tapping into genomics, environment, lifestyle, and even real-time data from wearable devices, Drs. Schork and Goetz discuss developing highly individualized approaches that don't just treat illness—they aim to prevent it. Together, they unpack how this shift could redefine everything from how drugs are tested, to how diseases are managed, and even how we define “health.” They discuss cutting-edge innovations like anti-sense oligonucleotides—drugs custom-made for an individual's genetic code—and the rise of geroprotectors, compounds designed to support whole-body wellness as we age. They discuss the difficulties of such specific treatments and the differences in the way different patients might metabolize and respond to the same medicine. The future of medicine isn't one-size-fits-all. It's N-of-1—and it might just be closer than you think.

Article by Connor Yeck Plunge into the shallows off the Florida Keys, Hawaii or the Great Barrier Reef in Australia and you are likely to meet a startling sight. Where there were once acres of dazzling coral - an underwater world of dayglo greens, brassy yellows and midnight blues - is now a ghostly landscape, with many reefs seemingly drained of their pigment. Caused by stressful conditions like warming ocean temperatures, coral bleaching is a leading threat to some of our planet's most diverse and vital ecosystems. Now, a team of researchers has found that some corals survive warming ocean temperatures by passing heat-resisting abilities on to their offspring. Corals teach their offspring to beat the heat The findings, published in the journal Nature Communications, are the result of a collaboration between Michigan State University, Duke University and the Hawaii Institute of Marine Biology, or HIMB, at the University of Hawaii at Mnoa. This work, funded by the National Science Foundation and a Michigan State University Climate Change Research grant, is crucial in the race to better conserve and restore threatened reefs across the globe. Coral reefs are habitats for nearly a quarter of all marine life, protecting coastlines from storms and erosion and supporting the livelihoods of millions of people around the world. Though still alive, bleached corals are at a much higher risk of disease, starvation and eventual mortality. In their latest study, the team explored how resistance to thermal stress is passed down from parent to offspring in an important reef-building species known as rice coral. These findings are helping researchers breed stronger, heat-tolerant generations to better face environmental stress. "The Coral Resilience Lab in Hawaii has developed amazing methods to breed and rear corals during natural summer spawning," said Spartan biochemist and study co-author Rob Quinn, whose lab takes samples of these corals and generates massive datasets on their biochemistry with instruments at MSU. "This is a true scientific collaboration that can support coral breeding and reproduction to cultivate more resilient corals for the warming oceans of the future." A colorful crowd The kaleidoscopic of shades we associate with healthy coral is the product of a bustling exchange of resources between a coral animal and its algae partners. When all is well, you might think of this relationship as that of tenants living in a home and paying a bit of rent. In exchange for cozy, sheltered spaces found within the coral tissue as well as nutrients, algae use photosynthesis to produce sugars. These sugars can provide up to 95% of the energy that coral needs to grow and form the sprawling, breathtaking reefs we know. In tropical waters often lacking nutrients, disruptions in this exchange - like those that occur during bleaching events - can be disastrous. When looking at a specimen of coral that's suffered bleaching, you're glimpsing a coral that's "kicked out" its algae, leaving behind a pale skeleton. "Corals are like the trees in an old growth forest; they build the ecosystems we know as reefs on the energetic foundation between the animal and algae," explained Crawford Drury, an assistant researcher at the Coral Resilience Lab at HIMB and co-author of the study. In the waters of Kaneohe Bay, the Coral Resilience Lab is spearheading research to best understand this coral reef ecology and the molecular mechanisms driving thermal stress. The lab is likewise pioneering the breeding of thermally resistant coral for experiments and the restoration of reefs, a highly specialized process few labs in the world can achieve. So, while you'd usually be hard pressed to find fresh coral for study in East Lansing, MSU's partnership with the Coral Resilience Lab has led to a globe-spanning collaboration that closes the gap between field and laboratory. "HIMB and MSU have developed a really amazing partnership. I'm just happy they've let me be a ...

Rerun: Calculating Threats from Rising Temperatures Using Heat Indexing, with Professor David Romps

Extreme Heat: More Dangerous Than We Think?Extreme heat, one of the adverse consequences of climate change, exacerbates drought, damages agriculture, and profoundly impacts human health. Heat is the top weather-related killer in the United States, contributing to deaths that arise from heart attacks, strokes, and other cardiovascular diseases. As temperatures are projected to increase, so will the risk of heat-related deaths. Urban heat islands, cities with large numbers of buildings, roads, and other infrastructure, are ‘islands' of hot temperatures due to the reduced natural landscape, heat-generating human-made activities, and large-scale urban configuration. More than 40 million people live in urban heat islands in the United States, with this number only increasing as people continue to move from rural to urban areas. Around 56% of the world's total population lives in cities. Those living in large cities are more vulnerable to the effects of extreme heat, with research showing an increased mortality risk of 45% compared to rural areas. The risk of heat-related exhaustion and death is a major public health concern that is exacerbated by the climate crisis. The National Weather Service is in the process of creating a new interface known as HeatRisk, which uses a five-point scale to monitor the heat-related risk for vulnerable populations based on local weather data and health indicators. By mapping heat risk, climate scientists hope that individuals will now have a better understanding of the safety concerns associated with being outside during times of extreme heat. Understanding Heat Index DynamicsBefore stepping outside, most individuals check the daily weather prediction to get a sense of the average temperature. In order to measure the perceived temperature, climate scientists use a heat index, a calculation that combines air temperature and relative humidity to create a human-perceived equivalent temperature. Accurate prediction of the heat index is imperative as every passing year marks the warmest on record, with dangerous extreme heat predicted to become commonplace across arid regions of the world. Therefore, tracking such calculations is necessary in assessing future climate risk. Areas especially vulnerable to extreme heat heavily rely on an accurate prediction of temperature to determine if it is safe to go outside.However, there are over 300 heat indexes used worldwide to calculate the threat from heat, defeating the potential universality of this metric. Each heat index weighs factors differently, making it difficult to differentiate between various metrics. Dozens of factors are used to estimate the daily temperature based on predictions of vapor pressure, height, clothing, or sunshine levels. In addition, most heat indexes report the temperature assuming that you are a young, healthy adult and are resting in the shade, not in the sun. If outdoors, the heat index could be 15 degrees higher. If you are older, you may not be as resilient during intense temperatures.As a result, many climate scientists are calling for heat indexes that reveal the apparent risk of being outdoors on any given day. The elderly, children and infants, and those suffering from chronic diseases are more vulnerable to high temperatures than healthy, young adults, which needs to be accounted for when surveying temperature risk. Advanced Heat Assessment Tools: HeatRisk and WBGTThe National Weather Service's HeatRisk index is different from previous models as it identifies unusual heat times and places, also taking into account unusually warm nights. As such, it provides a more universal measure accounting for the degree to which people in the area are acclimated to various heat temperatures. The HeatRisk index can thus be used to gauge levels of danger associated with temperature, potentially altering an individual's behavioral patterns. For those working in outdoor fields, the WetBulb Globe Temperature (WBGT) measure can be particularly useful as a way to measure heat stress as it takes into account temperature, humidity, wind speed, sun angle, and cloud coverage. Different from the heat index, the WBGT includes both temperature and humidity and is calculated for areas in the shade. If not exercising or working outdoors, people can revert to the HeatRisk scale to calculate the potential hazards of being outside for longer periods. Heat Indexes are Harder to Calculate Than They AppearBecause scientists have to account for a variety of factors like geography, physics, and physiology, establishing a truly universal heat index is unlikely. For regions like Colorado, creating the criteria for a heat advisory has proven shockingly difficult. Heat indexes typically rely on temperature and humidity, however, the Colorado landscape is so dry that an advisory is very rarely triggered, even during heat waves. In such scenarios, the HeatRisk index provides a better gauge for outdoor safety. Most people underestimate the dangers of extreme heat and often ignore warning messages from local authorities. Educational programs are vital in informing the public on the dangers of extreme heat.Who is David Romps?David Romps, UC Berkeley professor of Earth and Planetary Science, is at the forefront of heat index research. Romps has found that those exposed to extreme heat suffer restricted blood flow and are often unable to physiologically compensate. Through his research, Romps believes that heat index calculations often underestimate the potential heat impacts on individuals, with the human body being more susceptible to heightened temperatures than commonly understood. Further ReadingCenter for Climate and Energy Solutions, Heat Waves and Climate ChangeHuang, et.al, Economic valuation of temperature-related mortality attributed to urban heat islands in European cities, Nature Communications, 2023National Weather Service, What is the heat index?National Weather Service, NWS Heat Risk PrototypeNational Weather Service, WetBulb Globe TemperatureSharma, More than 40 million people in the U.S. live in urban heat islands, climate group finds, NBC News, 20232023 was the world's warmest year on record, by far, NOAA, 2024Coren, The world needs a new way to talk about heat,  The Washington Post, 2023Hawryluk and KFF Health News, A New Way to Measure Heat Risks for People, Scientific American, 2022UC Berkeley Heat Index Research, David RompsUS EPA, Climate Change Indicators: Heat-Related DeathsUS EPA, What are Heat Islands? For at transcript of this episode, please visit  https://climatebreak.org/calculating-threats-from-rising-temperatures-using-heat-indexing-with-professor-david-romps/

For years, scientists have grappled with differing values derived from cosmic microwave background radiation and supernova observations. Lead author Wendy Friedman discusses how recent findings suggest that the standard model of cosmology holds up, with the Hubble constant now estimated at 70.4 kilometres per second per megaparsec, aligning more closely with earlier measurements. This breakthrough could reshape our understanding of the universe's expansion and evolution.Venus's Thin CrustNew research indicates that Venus's crust is unexpectedly thin, challenging previous assumptions about the planet's geology. A study published in Nature Communications reveals that Venus lacks the tectonic activity seen on Earth, resulting in a crust that is about 40 to 65 kilometres thick. This research proposes a model of crust metamorphism that could explain how volcanic activity persists on Venus, despite the absence of plate tectonics. Upcoming missions, including NASA's Davinci and Veritas, aim to gather more data that could confirm these findings and enhance our understanding of Venus's geological processes.Building Blocks of Stellar FormationA recent study highlights that the formation of stars is influenced not only by the amount of gas in a galaxy but also by its distribution. Observations from the WALLABY survey, conducted using the Australian Square Kilometre Array Pathfinder Telescope, reveal that star formation is concentrated in areas with higher gas density. Lead author Seona Lee explains how this research sheds light on the intricate processes that govern star formation, suggesting that gas location is critical for the birth of new stars across various galaxy types.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journalhttps://iopscience.iop.org/journal/0004-637XNature Communicationshttps://www.nature.com/naturecommunications/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 66 for broadcast on 2 June 202501:00 Resolving the Hubble constant debate12:15 Venus's surprisingly thin crust22:30 Building blocks of stellar formation30:00 Science report: New links between autism and Parkinson's disease

Send us a textAnswer a few questions to help me improve this podcast here.We all want to live long and well—but how do we determine how many good years we have ahead?In this episode of Live Long and Well with Dr. Bobby, we explore how to estimate both our total lifespan and the number of years we can expect to remain active and pain-free. Dr. Bobby reflects on personal experiences, emerging science, and time-tested frameworks to help you reframe your health trajectory with clarity and motivation. While we may not find exact answers, the tools and thought experiments shared in this conversation can shape the way we live now—and influence how we plan for the future.We begin with why this topic matters, touching on personal stories of loss, aging milestones, and medical advancements. Then we move into three frameworks: how many years you might live (using tools from actuarial tables to cardiovascular risk calculators), how many of those years might be "good," and the wildcard of unpredictable events.The simplest predictor comes from actuarial life tables, which estimate life expectancy by age and sex. A 55-year-old man today might expect to live to 79; a woman to 82. More advanced tools include the Framingham Risk Score, which factors in cholesterol, blood pressure, smoking status, and diabetes to estimate 10-year cardiovascular risk. Research suggests that sharing these risk scores can lead to behavior changes, as shown in this meta-analysis of 28 studies and preliminary evidence of outcome improvements.On the genetics side, polygenic risk scores offer a glimpse into inherited risks, though they remain research tools for now (Nature study). More accessible are tests for specific genes like APOE4, which increases the risk of dementia (PubMed).Beyond numbers, simple physical tests can offer insight. The Brazilian sit-stand test links mobility with mortality risk: fewer than 8 points doubles your six-year mortality risk. Grip strength, too, is a strong predictor of all-cause mortality across 17 countries (PubMed).While biologic clocks based on DNA methylation are generating buzz, their utility remains limited due to variability between samples and testing methods (Nature Communications).When it comes to estimating “good” years—those lived free from major pain or disability—the data are sparse. Some disease-specific tools (e.g., for MS or dementia progression) exist, but there's no universal actuarial equivalent. However, we know muscle mass and aerobic capacity decline predictably with age—1–2% muscle loss per year and a 10% drop in aerobic fitness per decade (OUP Journal). Predicting your future function can begin with assessing how far you can walk, whether stairs leave you breathless, or how your weight and strength compare to a decade ago.Finally, we can't forget unpredictable events: the odds of a serious fall increase significantly after 65, and vision or hearing loss multiplies that risk (NCOA). Building physical resilience now can reduce these odds—see
