Science

Today, I’m thrilled to share what I believe is the biggest breakthrough in microbiome science for a decade. Nature Magazine, the world's most influential scientific journal, has just published a scientific paper by ZOE's scientists, establishing the first reliable, repeatable, global way to measure the health of an individual’s gut microbiome. It represents the culmination of eight years of work at ZOE. Scientists have been trying to solve this puzzle for more than 20 years, right back to when they first discovered how important our gut microbes are for our health. It’s been achieved only because more than 34,000 ZOE members took part in this research. We’ve known for a long time that the microbiome is linked to cholesterol, inflammation, blood sugar control and even how we store fat. But we’ve never had a clear, evidence-based way to measure how healthy a microbiome actually is. This analysis finally delivers it, revealing a global ranking of microbes that works across populations, diets and environments. The insights are remarkable. Among the top 50 “good microbes” linked with better health, 22 were completely unknown to science until today, and most of the others have never been successfully grown in a lab. We also discovered clear links between these good microbes and health outcomes: healthy individuals carry around 3.6 more of these beneficial species, and people at a healthy weight carry about 5.2 more than those living with obesity. We also found a strong connection to diet. People eating healthier diets consistently have microbiomes that score better on this ranking. What we eat shapes our gut health, and now we can measure this relationship with unprecedented clarity. ZOE was created to enable microbiome research at a scale that traditional science has been unable to fund, and use this research to create actionable advice that can transform our gut health. This is a major milestone in that journey. I’m delighted to say that as a result, this breakthrough science is immediately available for the public to investigate their own microbiome through ZOE’s new Gut Health Test in the UK, and this is coming soon in the US. You can now receive not only a reliable measurement of how healthy your microbiome is as you change their diet, but also discover the health of clusters of gut microbes in your gut affecting metabolism, inflammation and more. To all our amazing ZOE members who have participated in our science: you made this possible. You are transforming our understanding of the microbiome. Thank you so much. I hope you feel as proud and excited as I do. I should note that your research is now published in Nature, which is the ultimate scientific accolade, and you can definitely brag about that with your friends! If you think this science could help others understand their health, I’d love for you to share it. You’ll find links to more details from our findings and access to the paper in the comments.

🌍 NASA - National Aeronautics and Space Administration, in collaboration with data from the World Meteorological Organization, merges satellite observations, advanced models, and immense computing power to monitor aerosols in our atmosphere. These tiny, invisible solid or liquid particles — including black carbon (orange/red), sea salt (cyan), dust (magenta), and sulfates (green) — travel vast distances, affecting air quality, human health, climate, and visibility far from their source. 🔹 In South America, black carbon from wildfires burning in the Amazon rainforest drifts across the continent. 🔹 Over the Atlantic, massive plumes of dust from Northern Africa journey westward toward the Americas, influencing ecosystems, weather, and even hurricane formation. This striking visualization, powered by NASA’s Goddard Earth Observing System (GEOS) model and informed by WMO’s authoritative climate data, delivers realistic, high-resolution weather and aerosol insights. These data streams fuel #AI innovation and help provide customized environmental predictions — critical tools for #climateresilience and disaster preparedness #EW4ALL. ➡ A reminder: Every particle tells a story about the planet’s interconnected systems — and our shared responsibility to protect them

The impact of climate change on the SDGs 🌎 The latest State of the Global Climate 2024 report from WMO provides a clear assessment of how accelerating climate change is affecting global stability. With 2024 recorded as the hottest year on record—1.55°C above pre-industrial levels—the implications extend far beyond temperature increases. The findings highlight the direct and systemic risks climate change poses to achieving the UN Sustainable Development Goals (SDGs). Rising temperatures, ocean acidification, sea-level rise, and glacial melt are driving widespread environmental and socio-economic disruptions. These changes are not occurring in isolation; they are interconnected, amplifying existing challenges related to food security (SDG 2), water availability (SDG 6), economic resilience (SDG 8), and biodiversity loss (SDGs 14 & 15). Ocean changes are among the most critical risks. Increasing ocean temperatures and acidification are disrupting marine ecosystems, reducing fish stocks, and weakening the ocean’s ability to act as a carbon sink. This has significant consequences for coastal communities, food security, and global supply chains. Glacial loss and sea-level rise are reshaping landscapes, affecting infrastructure, water resources, and human settlements. Coastal erosion, land degradation, and increased flooding threaten urban development (SDG 11), economic productivity (SDG 9), and disaster resilience (SDG 13). These impacts also contribute to population displacement, further straining social and economic systems. The increase in extreme weather events, from heatwaves to hurricanes, is exacerbating global inequality. Agricultural losses, infrastructure damage, and rising adaptation costs are disproportionately affecting developing regions, slowing progress toward economic stability, sustainable production, and resource security (SDGs 8 & 12). The WMO report emphasizes that while exceeding 1.5°C in a single year does not mean the Paris Agreement target has been breached, the trend underscores the urgency of reducing emissions and strengthening adaptation strategies. Without immediate action, climate risks will continue to escalate, undermining progress toward the SDGs and increasing long-term economic and environmental costs. Addressing these challenges requires systemic policy shifts, investment in climate resilience, and cross-sector collaboration. As climate change intensifies, integrating sustainability into decision-making at all levels will be essential to mitigating risks and safeguarding global development objectives.

I can always tell if an analyst is illogical by this one sign: Their presentations. When it comes to sharing insights, *how* you structure your message matters just as much as *what* you’re saying. Two simple concepts can make your presentations more effective: 1) Vertical logic 2) Horizontal logic ——— 1) Vertical logic is about focus Every slide should have one clear takeaway, which is stated right in the title (not descriptive like “Overview” or “Results” but something like “Sales dropped due to supply delays”). Everything else on the slide - charts, text, visuals - should support that message. ——— 2) Horizontal logic is about flow Each slide should build naturally from the one before it. Click through your deck and read only the slide titles. Does it read like a story from start to finish? ——— When you have both vertical and horizontal logic, your message is clearer, your deck flows, and your audience remains engaged. Here’s my quick checklist before presenting: ✅ Can I follow the storyline by reading just the slide titles?  ✅ Does each slide build on the one before it? ✅ Is the takeaway of each slide instantly clear? If not - back to editing! P.S. New here? I’m Morgan. I share my favorite data viz and data storytelling tips to help other analysts (and academics) better communicate their work.

In Okinawa, Japan, the average life expectancy is 84 years. In India, it's 67 years. That’s 17 years of missed birthdays, moments, and memories. Why? The secret isn’t medicine or money. It’s small, daily habits that protect the body and mind over time. ▶︎ 1. They eat until 80% full It’s called ‘Hara Hachi Bu’. No overeating. No “clean your plate” pressure. It gives their metabolism less to process - and reduces inflammation over time. ▶︎ 2. Daily movement is built into life They follow the principle of ‘Karada O Ugokasu’ - “move your body naturally.” Instead of formal exercise, they walk to visit neighbors, and tend gardens every day. The goal isn’t intensity. It’s consistency through natural motion. ▶︎ 3. Plant-heavy, simple meals Okinawans follow the ‘Washoku tradition’ - a traditional Japanese eating style focused on balance, seasonality, and variety. Their plates are small. Their portions are modest. Even chopsticks help - slowing down eating and reducing bite sizes. ▶︎ 4. Strong community ties They have ‘Moai’ - tight-knit social groups that support each other for life. This community helps lower stress, strengthens immunity, and is linked to reduced risk of chronic disease and early death. ▶︎ 5. Purpose beyond work They call it Ikigai - a reason to get up each morning. Whether it’s mentoring younger generations, work, art, or caring for plants - they stay mentally and emotionally engaged well into their 90s. The result? Lower rates of diabetes, heart disease, cancer, and depression - even in their 90s. Remember, none of this requires more money or more effort. Just small shifts in how we live each day. Hit repost 🔁 if this made you rethink your habits. Someone in your connections might need that nudge too. #health #wellness #longevity

🌍 We Can’t Afford to Get Climate Policy Wrong—A Look at the Data Behind What Really Works 🌍 In the race against time to combat climate change, bold promises are everywhere. But here’s the critical question: Are the policies being implemented actually reducing emissions at the scale we need? A groundbreaking study published in Science, cuts through the noise and delivers the insights we desperately need. Evaluating 1,500 climate policies from around the world, the research identifies the 63 most effective ones—policies that have delivered tangible, significant reductions in emissions. What’s striking is that the most successful strategies often involve combinations of policies, rather than single initiatives. Think of it as the ultimate teamwork: when policies like carbon pricing, renewable energy mandates, and efficiency standards are combined thoughtfully, the impact is far greater than any one policy could achieve on its own. It’s a powerful reminder that for climate solutions the whole is indeed greater than the sum of its parts. Moreover, the study’s use of counterfactual emissions pathways is a game changer. By showing what would have happened without these policies, it provides a clear, quantifiable measure of their effectiveness. This is exactly the kind of rigorous evaluation we need to ensure that every policy counts, especially when we’re working against the clock. If we’re serious about meeting the Paris Agreement’s targets, we need to focus on what works—and this research offers a clear roadmap. Let’s champion policies that have proven to make a difference, because we don’t have time to waste on anything less. 🔗 Full study in the comments #ClimateAction #Sustainability #PolicyEffectiveness #ParisAgreement #NetZero #ClimateScience

My colleague Prof. Eleanor Maguire passed away this weekend after a long battle with cancer. Her contributions to #neuroscience have shaped how we understand memory and navigation, leaving a lasting legacy. One of Eleanor’s groundbreaking discoveries was that when a London taxi driver learns the 25,000 windy streets of London together with thousands of landmarks (collectively called “the Knowledge”), it physically changes their #brain. A part of the brain called the #hippocampus is important both for making new memories and for navigating one’s environment. For aspiring black cab drivers, learning the Knowledge pushes the hippocampus to adapt in remarkable ways. Eleanor and her colleagues used #MRI to measure the hippocampus in taxi drivers compared to a control group and discovered it was larger in the taxi drivers. In other words, London cabbies have special brains that are particularly well suited for their work. This raises a really interesting question: Are they born with a larger hippocampus and therefore better able to become taxi drivers or does learning the Knowledge change their brains? To answer this, Eleanor and her team ran a follow-up study where they followed 39 trainee taxi drivers from the beginning of their training to when qualified approximately 4 years later. Each received a brain scan at the beginning and end of their training. 👉 Before training, the aspiring taxi drivers showed no difference in hippocampus size compared to matched control volunteers. 👉 After training, the newly qualified taxi drivers were found to have larger hippocampi than they did 4 years ago and also larger than the control volunteers. In other words, even as an adult, learning the Knowledge has a strong effect on the brain that can be measured using MRI. Eleanor’s work has become one of the most well-known examples of #neuroplasticity, which is the brain’s remarkable ability to change and adapt throughout life. A few years ago, a group of students were visiting UCL’s Functional Imaging Lab. They had learned about her taxi study in their A-level psychology class so when they discovered that Eleanor worked there, there was a frenzy of excitement! They couldn’t believe that they got to meet the “Maguire” whose work they had read in school. It was absolutely charming! Although best known for work with taxi drivers, Eleanor made substantial contributions to memory and hippocampal function including: 👉 Discovering that patients with amnesia cannot imagine the future 👉 Showing that it is possible to decode individual memories by analysing patterns of activity in the hippocampus 👉 Clarifying the relation between memory for life episodes, the ability to imagine the future, and the ability to navigate spatial environments Eleanor’s work is a powerful reminder of the brain’s potential to adapt and grow throughout life. May her legacy inspire all of us to keep learning and exploring the frontiers of science.

Why so few female professors? 🔹97% of female professors say "barriers within academia" such as "implicit bias in evaluations, male networks and an unwelcoming academic culture" play an important role. 🔹Only 22% of male professors mention such barriers. Instead, male professors are more likely to point to "family factors" and "women's own interests and preferences". 🔹A majority of male professors shows "hesitation, uneasiness or reluctance when asked how the low proportion of female professors can be explained". Only 3% of female professors do so. These are among the key results of a study by sociologists Margaretha Järvinen and Nanna Mik-Meyer, based on 77 qualitative interviews with full professors in economics, political science, and sociology in Denmark. Moreover, the study identifies "a ‘silent standpoint’ among the participating male professors: the idea that women are generally less qualified than men as candidates for full professorships." Read the full study here: Margaretha Järvinen and Nanna Mik-Meyer (2026), The Silent Standpoint: How Professors Explain Gender Disparities in Academia, British Journal of Sociology, forthcoming: https://lnkd.in/eG6UkJ6x (open access) The quotes from the interviews in the "Supporting information" file are also quite illuminating.

💥A nanorobot just killed a cancer cell. Not with chemicals. But with intelligence. This microscopic machine hides its weapon inside a DNA nanostructure — and only unlocks it in the tumor’s microenvironment. Healthy cells stay untouched. As Professor Björn Högberg from Karolinska Institutet explains: “If you were to administer it as a drug, it would indiscriminately start killing cells in the body... To get around this, we’ve hidden the weapon inside a nanostructure built from DNA.” What most people don’t know: These DNA nanostructures aren’t just passive containers. They can sense, decide, and act — like tiny programmable agents operating inside the human body. It’s not science fiction anymore. It’s agentic medicine. My take: We talk about AI transforming business — but the next frontier is AI transforming biology. When intelligence becomes molecular, health stops being reactive and becomes adaptive. We’re not just curing diseases; we’re teaching cells how to defend themselves. It’s a glimpse of what happens when biology meets computation — and when humans stop programming code, and start programming life. #AI #Nanotechnology #Medicine #DNA #Innovation #AgenticAI
