Perseverance Rover's Potential Evidence of Life on Mars: NASA's Perseverance rover has uncovered what could be the strongest evidence yet for microbial life on Mars. The discovery of "leopard spots" on a rock in the Bright Jingle Formation contains organic carbon-rich material, clay minerals, and iron sulfide minerals that suggest biological processes akin to those of Earth microbes. While skepticism remains, the analysis indicates that these findings are most likely biological in origin, pending further examination through the Mars Sample Return mission.Risks of Asteroid Deflection Missions: A new study reveals that asteroid deflection missions might inadvertently increase the risk of Earth impacts. Researchers found that improper deflection could steer asteroids into gravitational keyholes, leading them onto collision courses with Earth. Sophisticated planning and probability maps are essential for safely redirecting asteroids, highlighting the complexity of such missions.James Webb Telescope's Massive Stellar Jet Discovery: The James Webb Space Telescope has captured astonishing images of an eight-light-year-long stellar jet originating from a massive protostar in the Sharpless 2284 Nebula. This discovery provides insights into the formation of massive stars and the dynamics of stellar jets, which scale with stellar mass.Pentagon's New Missile Defense Satellites: The Pentagon has launched 21 satellites for a new missile defense constellation, part of a plan to deploy 154 satellites in low Earth orbit. This innovative approach reduces costs significantly and enhances capabilities to detect modern threats like hypersonic weapons, marking a shift in military satellite economics.Nasa's Creative Helicopter Training: NASA has introduced a helicopter flight training course in the Colorado mountains to simulate lunar landing conditions for the Artemis missions.

Put on your party hat and wet suit because it is Cephalopod Week, Science Friday's annual celebration of all things, octopuses, squid, and cuttlefish. To kick things off, we're bringing you an ode to the octopus arm. You may have heard that octopuses can use their arms to “taste” their surroundings, which they use for finding food. Now, researchers have unlocked a key mechanism in the octopus sensory system. Octopuses use their suckers to detect harmful microbes on the surface of crab shells or even their own eggs.  Host Flora Lichtman talks with molecular biologist Nicholas Bellono about the latest in octopus sensory science. Guest: Dr. Nicholas Bellono is a professor of molecular and cellular biology at Harvard University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

The dizzying variety of options, the amazing range of flavours, and for some of us, the sheer quantity that you can eat. It's easy to see the appeal of a buffet. It takes the stress out of choosing what to eat - just have it all! But are there risks that we need to think about? Food hygiene specialists suggest there might be.各种各样的选择，令人惊叹的风味范围，对于我们中的某些人来说，您可以吃的大量数量。 很容易看到自助餐的吸引力。 选择吃什么 - 只要全部吃东西！ 但是，我们需要考虑的风险吗？ 食品卫生专家建议可能会有。Restaurant and hotel buffets can be a food poisoning risk. The large number of different dishes and people serving themselves creates opportunities for cross-contamination. Microbes can be transferred from people to dishes, from dishes to people and from one dish to another. Even the air can transfer microbes to your food. It's easy to see how an entire buffet could end up contaminated. Food temperature creates another risk factor. It's easy for food to be kept lukewarm and in the danger zone between 8C and 63C where bacteria and other microbes grow and multiply easily.餐厅和酒店自助餐可能是食物中毒的风险。 大量不同的菜肴和为自己服务的人们创造了交叉污染的机会。 微生物可以从人转移到菜肴，从菜肴到人，从一道菜到另一种菜肴。 甚至空气也可以将微生物转移到您的食物中。 很容易看到整个自助餐最终如何污染。 食物温度会产生另一个危险因素。 食物很容易保持不冷热，并在8c至63c之间的危险区域，在那里细菌和其他微生物易于生长和繁殖。Restaurants that manage buffets well can reduce the risks. Hot food should be replaced after two hours and cold food after four. It's important that the old food is disposed of and that containers are not just topped up, allowing the older food to contaminate fresh items. Hot food should be kept above 63C, and cold food should be refrigerated.家管理自助餐的餐厅可以降低风险。 两个小时后，应在四个小时后更换热食品。 旧食物要处置，并且容器不仅要装满，而且允许较旧的食物污染新鲜物品，这一点很重要。 热食应保持在63℃以上，并应冷藏冷食。However, any attempts by hospitality businesses to reduce risks can easily be undone by careless clients. There are many ways that diners can unwittingly or thoughtlessly increase the risks. Tongs and ladles can be contaminated by those who do not wash their hands, or who reuse their plates when getting a second helping. Food on display can be contaminated by people using the wrong utensil or who accidentally drop the handles into bowls of food. That's before even mentioning those who cough or sneeze near the buffet.但是，款待业务降低风险的任何尝试都可以被粗心的客户轻松撤销。 食客可以通过多种方式不知不觉地增加风险。 那些不洗手，或者在获得第二次帮助时重复使用盘子的人可能会污染钳子和梯子。 使用错误的餐具或意外将手柄放入食物碗的人可能会污染展出的食物。 那是在提到那些在自助餐附近咳嗽或打喷嚏的人。So, to enjoy a buffet, while keeping the risks as low as possible, you should check to see that it is well-managed by the restaurant or hotel, that others are following good hygiene rules and that you do the same. Even so, a buffet is likely to be more risky than other types of restaurants.因此，要享受自助餐，同时保持风险尽可能低，您应该检查一下餐厅或酒店的管理良好，其他人正在遵守良好的卫生规则，并且您也这样做。 即便如此，自助餐可能比其他类型的餐馆更具风险。

My original recipe for SIBO Yogurt included three microbes chosen for their ability to colonize or germinate in the small intestine and produce bacteriocins, natural peptide antibiotics effective in killing the species of SIBO. The original formulation therefore specified L. reuteri, L. gasseri, and B. coagulans. However, B. coagulans proved to be unreliable in generating the high microbial counts we desire to overcome the trillions of invading fecal microbial species of SIBO. I therefore replaced it with B. subtilis, a virtual powerhouse of a bacteriocin producer, producing up to 7 bacteriocins, thereby giving you greater power in pushing back invading fecal microbes in SIBO. So in this episode of the Defiant Health podcast, let me get you acquainted with this powerful microbe that, I believe, can provide major advantages in your efforts to take back control over gastrointestinal and overall health. Support the showYouTube channel: https://www.youtube.com/@WilliamDavisMD Blog: WilliamDavisMD.com Membership website for two-way Zoom group meetings: InnerCircle.DrDavisInfiniteHealth.com Books: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

What happens when a preventable infection takes the life of someone you love? In this episode, Christian John Lillis shares the heartbreaking story of losing his mom to C. difficile, a bacterial infection, and how that loss inspired his mission to fight back. He talks about what everyone needs to know about C. diff: the warning signs, how it spreads, the importance of early treatment and steps we can all take to prevent it becoming more serious. This is more than a story of loss—it's a call to action for awareness, advocacy and protecting our loved ones.

This week we had the pleasure to be joined by Nikolai Siimes, who is a more than human geographer at Waipapa Taumata Rau/The University of Auckland. In addition to his academic research, he has worked for almost a decade in the wine sector in different capacities. He describes his PhD as an ethnography of wine, which uses wine as a case to follow microbes and human–microbe relations in agriculture. He uses “sensory and embodied ethnographic methods to examine microbial agency, agricultural governance, and the sensory-material politics of food and drink.” Nikolai starts our conversation by reminding us that microbes are everywhere and make up everything. Nikolai brings us to the microbial level and helps us think through their worlds and worldings and how our actions affect the microbial realm, for example with the use of pesticides in vineyards. This work takes microbes seriously as cultural agents within the world, rejecting simple accounts of microbes as inert and mechanistic. If you want to learn more about Nikolai's work, check out the links below:University Profile https://profiles.auckland.ac.nz/nikolai-siimes If you want to read some of Nikolai's publications:Having a drink with awkward Brett: Brettanomyces, taste(s) and wine/markets - An article on Awkward Brettanomyces https://onlinelibrary.wiley.com/doi/10.1111/nzg.12368Making Time with Microbes - A recent book chapter discussing microbial temporalities and sensory ways of relating to wine microbes http://doi.org/10.4324/9781032632995-11

Are germs truly the villains of human health—or have we misunderstood the body's healing process from the very beginning? In this eye-opening episode of the Know Better | Do Better Podcast, Autumn sits down with Liev Dalton, founder of Beyond Terrain, to dismantle mainstream medical myths and reveal the truth behind the terrain paradigm. From pleomorphism and the flaws of PCR testing to ancestral wisdom and the body's natural detox processes, Liev uncovers why germ theory may be the greatest medical misdirection of our time—and how reclaiming your health starts with honoring your body, not fearing it. If you've ever questioned the medical system, wondered why symptoms keep coming back, or felt drawn to holistic, root-cause healing, this conversation will challenge everything you thought you knew about illness, microbes, and healing.

In this episode, we continue exploring microbiology by talking with Dr. Katriana Popichak about the tiny troublemakers all around us: bacteria and viruses. What are they? How do they infect us? And, more importantly, how can we push back against them? Grab some hand sanitizer and settle in as we untangle fact from fiction about microbes, antibiotics, vaccines, and the science of keeping microbes under control so they don't ruin your day.

My guest today is Dr. Kenda Rigdon. Dr. Rigdon is a microbiologist with a PhD in microbiology and virology from the University of Alabama at Birmingham. Drawing from her expertise, she explores how the gut's microbial ecosystem—comprising bacteria, yeast like Candida and Malassezia, and other microbes—interacts with genetic and epigenetic factors to influence Autism. Dr. Rigdon highlights the critical role of the birthing process, particularly how vaginal delivery seeds a newborn's gut with beneficial microbes like lactobacillus, setting the stage for healthy development in the first three years. She also delves into how yeast overgrowth, nutrient competition (e.g., for tryptophan), and environmental factors like manganese and glyphosate exposure can disrupt this delicate ecosystem, potentially exacerbating autism-related symptoms.Dr. Rigdon shares insights into the surprising links between melanin, Neanderthal DNA, and Autism. She discusses how specific genetic mutations, such as MTHFR and PAI1, can intersect with Autism. Additionally, she connects melanin production—potentially influenced by gut yeast like Malassezia—to neurological health, drawing parallels with conditions like Parkinson's.

What shapes us most are often the things we can't see. From the trillions of microbes in our bodies to the emerging world of nanotechnology, invisibility is both power and risk. In this episode of Lipsticks on Labcoats, Ashlei Lewis explores the hidden layers of life, weaving in lessons from The Invisible Man to ask: when something is unseen, does it become more powerful… or more dangerous?

Microbes are everywhere, even in seeds! Indeed, seeds from various plants can host a community of different microbes. Despite how cool this sounds, we still have a lot to learn about seed microbiomes. Join me and Dr. Gilliam Burgmann as we explore questions like what kinds of microbes are present in seeds? How do these communities differ? Are microbes good, bad, or indifferent to the seeds that host them?

Your gut microbes don't just digest food, they can power you. In this episode, we uncover a hidden energy stream: short-chain fatty acids produced when microbes ferment plant fibers, potentially supplying anywhere from 2% to 10% of your daily calories. A new Cell study quantifies this microbial contribution with a unique level of precision, revealing how dietary choices drives the yield. We look at the mechanisms behind this energy exchange, , and show why increasing fiber intake is one of the most potent, underappreciated tools for improving metabolic health immune function, disease resistance, etc. We can now say it also contributes to energy flux.00:00 Introduction: The Hidden Fuel Source00:13 The Role of Gut Microbes in Energy Production01:16 How Gut Microbes Transform Fiber into Energy02:49 Measuring Microbial Energy Contribution04:51 Impact of Diet on Microbial Energy Harvest06:32 Significance of Microbial Fermentation07:37 Implications for Human Health and Diet09:19 Conclusion: Feeding Your Microbial PartnersPMID: 40744013Support the show

I've been soaking up this magical Leo season, picking berries at local farms and making plant infusions that feel like exactly what my body needs. It got me thinking about flow versus force - and how we've all been conditioned to swim upstream against our bodies instead of working with their natural wisdom.In this episode, I'm sharing what my garden taught me about healing, why I've made some bold boundary decisions in my practice, and how to move beyond the endless root cause hunting that keeps so many people stuck in health rabbit holes.I dive into a powerful case study of a 49-year-old client whose previous functional medicine approach had her on hormone precursors to "fix" imbalanced labs, while completely missing the terrain story her body was telling. When we looked at her hair mineral analysis and microbiome testing together, we discovered inflammation markers 10x normal, gut bacteria producing 318x normal levels of toxic methane gas, and a nervous system stuck in chronic threat detection mode.This is what happens when we treat symptoms instead of understanding terrain. Her minerals showed a body fighting systemic inflammation for months, while her gut revealed missing keystone species and an ecosystem completely out of balance. The internal pressure from this chaos showed up as sleepless nights, brain fog, vision issues, and that constant feeling of being overwhelmed by everything.This episode is a call-in for what I like to call the "conscious rebuilders" - people ready to stop fighting their bodies and start flowing with their innate wisdom. If you're tired of the endless testing cycles, supplement protocols that feel like warfare, and practitioners who treat your body like a broken machine, this conversation is for you.We talk about why minerals AND microbes must be addressed simultaneously, how to read your body's adaptation story instead of chasing root causes, and what it looks like to rebuild foundational terrain rather than just manage symptoms.My Minerals and Microbes program is evolving after over a year of working with this approach. I have spots available through August 9th at the current structure before it transforms to reflect everything I've learned about this deeper level of terrain restoration work.Ready to stop swimming upstream and start flowing with your body's wisdom?

Episode 312 People have been given genetically engineered microbes to prevent a common health condition - and it worked. The gut microbiome is now known to be associated with many health conditions - and in this case, the team managed to treat 9 people who get recurring kidney stones. With the gut's links to mental health, cancer and more, could engineered microbes be used to treat more conditions in the future? Is 1.5C dead? It's looking increasingly likely that we're going to breach 1.5C of global warming - the goal set out in the Paris agreement. So do we need to set a new goal now? As scientists come up with alternative numbers to aim for, many are worried that moving the goalposts will kill climate ambition. But is there a middle ground that keeps everyone happy? Where are all the aliens? We may now have a solution to the famous Fermi paradox, which questions why we've never met anyone else in the universe, despite the existence of many Earth-like planets. And it's all to do with tectonic plates - a geological phenomenon that may be rare outside of Earth, helping complex life to emerge on our planet.  Chapters: (00:39) Genetically modified gut microbes (07:03) Setting a new goal for global warming (17:20) Solving the Fermi paradox Hosted by Rowan Hooper and Penny Sarchet, with guests Grace Wade, Madeleine Cuff, Alex Wilkins, Ilana Seid, Robert Stern and Taras Gerya.

We live in a world filled with microbes—they're inside our bodies, in soil, in deep sea hydrothermal vents, and in your window AC unit. Some microbiologists are hopeful that finding more of these tiny organisms could help us address the climate crisis. Joining Host Flora Lichtman to talk about how are microbiologists James Henriksen and Lisa Stein.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Stephen Skolnick is a gut microbiome expert blogging at Eat Shit And Prosper. His most recent post argues that contra the psychiatric consensus, schizophrenia isn't genetic at all - it's caused by a gut microbe. He argues: Scientists think schizophrenia is genetic because it obviously runs in families But the twin concordance rates are pretty low - if your identical twin has schizophrenia, there's only about a 30%-40% chance that you get it too. Is that really what we would expect from a genetic disease? Also, scientists have looked for schizophrenia genes, and can only find about 1-2% as many as they were expecting. So maybe we should ask how a disease can run in families without being genetic. Gut microbiota provide an answer: most people “catch” their gut microbiome from their parents. Studies find that schizophrenics have very high levels of a gut bacterium called Ruminococcus gnavus. This bacterium secretes psychoactive chemicals. Constant exposure to these chemicals might be the cause of schizophrenia. I disagree with all of this. Going in order: https://www.astralcodexten.com/p/contra-skolnick-on-schizophrenia
