The ocean's health may depend on a tiny microbe inside fish
A surprising new discovery suggests that tiny microbes living inside fish may be helping shape the chemistry of the world’s oceans. Scientists found evidence that bacteria in the guts of marine fish work alongside their hosts to produce calcium carbonate, a mineral that plays an important role in ocean health and carbon storage. For years, researchers believed fish handled this process on their own, but the new findings point to a hidden partnership between fish and microbes.

Sharing her passion for science
By Danielle Rush Communications Specialist, Indiana University Kokomo Hisako Masuda, Indiana University Kokomo professor of biochemistry, was honored by the Indiana Academy of Science (IAS) as its 2026 Distinguished Scholar. The award is given to an individual who is recognized by the IAS as having an exceptional record of scholarship. Recipients are selected from nominations submitted to its awards committee. “I was surprised,” said Masuda, who joined IU Kokomo’s faculty in 2013. “I feel there are many good scientists in the Academy, so I wasn’t expecting it at all.” Patrick Motl, dean of the School of Sciences, said the Academy recognizes up to one member per year, and that Masuda is the second or third IU Kokomo faculty member to receive the commendation. “Clearly this speaks to the strength of Dr. Masuda’s accomplishments in research and scholarship and that her work stands out amongst her peers in Indiana,” said Motl, who received the award in 2019. “Many of the institutions that participate in the IAS are undergraduate institutions or primarily undergraduate institutions, but even having that caveat, Dr. Masuda has built and maintains a very active research program in her lab, working exclusively with undergraduates. She is passionate about science and can share that passion with her students. To carry on a quality research program with so many students involved in so many projects is truly remarkable and I am glad that the IAS acknowledged that for Dr. Masuda.” The IAS specifically commended her for involving more than 50 undergraduates in her research in bacterial metabolism, genomics, and their phenotypic plasticity at IU Kokomo, and publishing 23 articles with many student co-authors. Masuda’s current work primarily focuses on biodegradation and chemical repurposing of nylon. Using soil bacteria, her lab studies bacterial biodegradation of nylon and other environmental pollutants. She applies principles of green chemistry while developing a method to convert nylon waste into other nontoxic polymers. In collaborative work with health scientists, her lab investigates gut microbiomes of Indiana native birds as well as human subjects in a clinical study. She became interested in converting plastic waste while earning her Ph.D. at Rutgers University, working on methods to remove environmental waste not using chemicals or other intrusive methods. She learned about Nylon 11, which is used in pipes for transferring oil, interior components for cars, catheters, and in other industrial hard plastics. Nylon 11 is nontoxic, she added, so it is safe to include students in the research. “Those are considered to be nonbiodegradable, and have to go to a landfill,” she said. “I thought if we could come up with a way to biodegrade it, that would make some kind of impact.” Eventually, she wants to develop a product that would convert nylon waste to something useful, and to reduce waste and microplastics in the environment. “That would be my goal at some point, that we can make that change, and also make people more aware of their use of plastics,” she said. “I hope students stop to think about what we can do as scientists to address issues currently impacting us.” She appreciates the IAS for its support of scientific research at Indiana institutions, and IU Kokomo and the School of Sciences for providing funding for students to attend the Academy’s annual meeting. She added that IU Kokomo has also supported her research with funding from the School of Sciences and Academic Affairs. “Without that, I couldn’t do my research,” she said. Masuda has also earned a Senior Research Grant from the IAS, IU Kokomo’s Distinguished Research Award, and the IU Kokomo Junior Faculty Annual Research Award. She is a Fellow of the Indiana Academy of Science. Education is KEY at Indiana University Kokomo.

Scientists Stunned: Colossal Eggs Discovered 3,500 Meters Beneath an Active Volcano
Beneath an active seafloor volcano off Vancouver Island, researchers have documented a congregation of giant eggs at roughly 3,500 meters, a discovery that reframes how life can flourish under extreme conditions. The eggs belong to the Pacific white skate, an elusive deep‑sea species adapted to cold, crushing pressure and perpetual darkness. What seemed an unlikely nursery is actually a geothermally warmed refuge, where subtle heat helps embryos survive a marathon incubation. The finding links volcanic energy to a quiet engine of biodiversity, turning a hostile landscape into an incubator. A living volcano, a hidden nursery The seamount long assumed dormant now exhales mineral‑rich, shimmering plumes, proof of hydrothermal life at depth. Expedition cameras swept across black basalt and pale bacterial mats, revealing vents that pulse with warmth. That warmth, though modest by human standards, alters the physics of development for cold‑adapted embryos. In a realm where metabolism creeps, even a few degrees can mean faster growth and higher survival. The volcano is not only active; it is ecologically formative, drafting a blueprint for a thriving oasis. Giant eggs and a skate built for the abyss The Pacific white skate, Bathyraja spinosissima, is built for the abyss: broad wings, armored spines, and a life history that trades speed for endurance. Females lay outsized, rectangular “mermaid’s purses,” often 46–50 centimeters long, packed with rich yolk to fuel years of growth. In the frigid deep, embryos can require around four years to hatch, a timeline that magnifies every energetic advantage. The scale is striking—large eggs, large adults, and a textbook case of deep‑sea gigantism. The volcano’s gentle heat may literally shave months or years from the wait. Why heat matters at the bottom of the sea Hydrothermal circulation delivers low‑level warmth without the turbulence that would scatter fragile egg‑cases. Slightly elevated temperatures accelerate enzyme kinetics, nudging development along while keeping embryos within a safe range. Mineral‑laden fluids likely shape local microbiomes, which, in turn, can influence biofilms on egg surfaces. The environment acts like a slow, steady incubator, countering the deep sea’s tyrannies of cold and scarcity. For a species with long maturation and few offspring, every incremental boost compounds across generations. An ecosystem sculpted by fire and water Seafloor volcanoes create steep environmental gradients, stitching together hot vents, cool eddies, and mineral gardens into mosaic habitats. Microbes harvest chemical energy, seeding food webs that support crustaceans, fishes, and skates. Cameras documented egg‑cases nestled among rocky ledges, near communities nourished by vent‑driven chemistry. These islands of productivity behave like deep‑sea oases, sustaining life far beyond the vent orifice’s flickering light. The nursery’s success underscores how geological forces engineer biological opportunity. “Finding a cradle of life tucked beneath a breathing volcano reminds us that the planet’s harshest places can be profoundly generous.” What the discovery could change The nursery reframes conservation priorities in regions where volcanism quietly underwrites reproduction. Protecting hydrothermal corridors could safeguard entire lifecycles, not just charismatic adults spotted during occasional surveys. It also sharpens questions about how climate‑driven shifts in ocean circulation might influence vent activity, temperature fields, and embryo survival. With methodical mapping, time‑series cameras, and environmental DNA, scientists can track whether nurseries remain stable or drift with geologic rhythms. Key implications include: Enhanced understanding of deep‑sea reproduction at hydrothermal sites. New conservation targets centered on geothermal nurseries. Comparative studies with other volcanic regions, from the Galápagos to rift zones. Biotechnological insights from organisms adapted to long, cold development. Better models of how seafloor heat shapes regional biodiversity. Methods behind the revelation Remotely operated vehicles threaded through chimney fields, gathering video, temperatures, and mineral signatures. High‑definition imagery captured the distinctive, horned egg cases, their edges dusted with fine volcanic silt. Geochemical profiles mapped how heat and chemicals disperse, outlining the “thermal lanes” where eggs most cluster. Combined, these datasets reveal a nursery organized by geothermal topography, with egg‑cases concentrated in pockets of gentle, sustained warmth. A fragile boon in a changing ocean Deep‑sea environments feel remote, yet they intersect with global pressures: mining proposals, cable routes, and shifting oxygen levels. The nursery’s resilience hinges on stable heat flow, intact substrates, and minimal disturbance from noise or sediment. Safeguarding such places is not just about protecting novelty; it preserves a slow, ancient strategy that lets large, long‑lived animals endure in the coldest reaches of the Pacific. Where geology and biology meet, the planet’s deep time still writes living stories. This volcano‑warmed nursery adds a vital chapter to that story, revealing how subtle thermal gifts can tip the scales toward life in the abyss. With each dive, researchers trace the contours of an unseen world, where fire feeds water, and water—against all odds—feeds the future.

Glyphosate: A story of science, risk, and nuance
In the summer of 2014, a California groundskeeper named Dewayne Johnson started noticing patches of raw, weeping skin spreading across his body. He had spent years applying Roundup, Monsanto’s glyphosate-based herbicide, for a school district, sometimes drenched in it when equipment malfunctioned. By 2014, he had a diagnosis: non-Hodgkin’s lymphoma. In 2018, a jury awarded him $289 million in damages, later reduced on appeal. Tens of thousands of lawsuits followed. The story hasn’t quieted down. It’s all over the internet, swinging between “this will kill you, buy organic” and “relax, you’re fear-mongering.” Some of that recent chatter stems from an Executive Order protecting glyphosate and its production, which set off intense infighting within the MAHA movement. Some of it reflects a deeper truth: Americans genuinely care about harmful chemicals in their environment (see poll below). And the conversation isn’t going anywhere, with a Supreme Court case involving Monsanto set for this April. Glyphosate (the active ingredient in Roundup) is one of the most widely used herbicides in the world. But does glyphosate cause cancer? And how much exposure is actually risky? With so much mistrust in institutions and corporations (and some genuine conflicts of interest), making sense of the actual scientific evidence is genuinely hard. Here is a translation of what the scientific evidence actually says. Does glyphosate cause harm? Glyphosate is an herbicide that kills most plants it contacts rather than targeting specific species. It works by blocking an enzyme pathway (EPSPS) that plants and many microorganisms need to produce essential amino acids. Without those amino acids, the plant can’t grow and dies. Glyphosate was first developed by Monsanto in the 1970s and became ubiquitous after the company introduced “Roundup Ready” crops in the 1990s. In 2024, Bayer removed glyphosate from residential Roundup-branded products due to litigation pressure. But today it is still the most widely used herbicide in the world. Farmers also discovered they could spray it directly on crops like oats, lentils, beans, and peas just before harvest to dry them out faster and make harvesting easier. Because of its widespread use, it’s obviously really important to understand if it’s harmful to humans. The key principle: The dose makes the poison The most important concept in toxicology is that “the dose makes the poison.” Sixteenth-century physician Paracelsus articulated what remains the foundational principle of toxicology: sola dosis facit venenum. Water will kill you if you drink enough of it. Aspirin saves lives at 81 milligrams and causes internal bleeding at higher chronic doses. So, at what dose is glyphosate poisonous? The LD50 in rats (the dose that kills half the test animals) is around 5,600 mg/kg body weight. Table salt is roughly 3,000 mg/kg. By that classic measure, glyphosate is less acutely toxic than salt. But some people are exposed to a lot of glyphosate through their work. And among the general public, there are many questions about low-dose, cumulative exposure from multiple sources over long periods. Does glyphosate cause health problems? Cancer Correlation maps are striking, with one analysis finding that 60% of counties that spray the most glyphosate have non-Hodgkin’s lymphoma rates above the national average. But correlation alone doesn’t establish cause, which is why animal and human studies matter. In animals: Rat studies are typically what most fear is rooted in, but most people don’t know the study details on the dosage given to rats. A pooled analysis of the 13 most rigorous rat studies found evidence that very high doses, around 55,000 times greater than typical food residue exposure, can cause certain cancers. In humans: One of the strongest studies followed 55,000 herbicide users over 20 years and found no overall increased cancer risk. There was one signal: among those with the highest use, rates of acute myeloid leukemia (AML) appeared elevated. A broader meta-analysis of 18 human studies also found no overall cancer risk, though a separate meta-analysis focused specifically on non-Hodgkin lymphoma found that people with high cumulative glyphosate exposure faced a 41% higher relative risk compared to those with low or no exposure. These human studies are observational studies (randomized controlled trials would be unethical), and meta-analyses are only as reliable as the studies they pool. But the story seems consistent: at very high exposure levels, there may be some cancer risk. But that’s about as far as the science currently takes us. Emerging research: gut and reproductive health Gut: Because glyphosate targets a pathway that exists in some gut bacteria, scientists have questioned whether it could affect the microbiome. In mice, a 2023 University of Iowa study found that glyphosate altered gut bacterial composition and raised markers of intestinal inflammation. A 2024 systematic review found similar patterns: disrupted gut bacteria and problems with the mucus layer that protects the intestinal wall in mice. Whether this translates to humans is an open question. The human gut is highly variable and resistant, and we don't yet have strong studies confirming the same effects in people. Reproductive health: Animal studies have found that glyphosate-based herbicides can interfere with reproductive hormones, including disrupting egg cell development in mice and reducing the number of eggs available in sheep’s ovaries. However, the doses used in these experiments were high, so it’s not yet clear whether the same effects would occur in humans. On the human side, a 2021 pilot study led by Mount Sinai researchers tested urine samples from pregnant women across the U.S. and found glyphosate in 95% of them. The study also found a possible connection between higher glyphosate exposure during pregnancy and a subtle physical difference measured in female newborns. That said, some connections weren’t statistically reliable and this was a small study. The researchers themselves said more and larger studies are needed before drawing firm conclusions. What do regulators say about glyphosate safety? In 2015, the International Agency for Research on Cancer (IARC), part of the World Health Organization, classified glyphosate as "probably carcinogenic to humans" (Group 2A). The classification is worth taking seriously. But, there’s an important distinction: IARC classifies hazard, meaning the potential to cause harm under some conditions. It does not assess risk, which accounts for actual exposure levels and the real-world probability of harm. The U.S. EPA, the European Food Safety Authority, Health Canada, and regulatory agencies in Australia and Japan have all concluded that glyphosate is “unlikely to be carcinogenic to humans” at realistic exposure levels. They’re asking a different question: given how much of this people actually encounter, what is the probability of harm? Your actual exposure is what determines your actual risk. What does glyphosate mean for your daily life? At the grocery store: Food residues are small. The EPA’s acceptable daily intake is 1.75 mg/kg of body weight per day. To hit that threshold from oatmeal alone, a 150-pound adult would need to eat roughly 50 pounds of oats every day. But this calculation addresses only one pathway (food), and we don’t yet have robust tools to measure people’s actual total exposure. If reducing exposure matters to you, organic certification prohibits synthetic herbicides, and organic oat products generally test at lower or undetectable levels. Either way, a diet rich in whole grains, conventional or organic, is far better for your health than one that omits them out of fear of residues. On the farm: Occupational exposure is orders of magnitude higher than consumer exposure. Farmers and farm workers who mix, load, and apply glyphosate-based herbicides, especially without protective equipment, face meaningfully different risk profiles. Proper PPE isn’t optional. Integrated weed management strategies that rotate chemical modes of action are also worth taking seriously, both for health and for long-term effectiveness. If you live near a farm: Spray drift is real. Concentrations near field edges can spike during and after application, particularly on windy days. This is an area where I think public health could really step up and empower rural communities with buffer zones, rather than placing the onus on individuals. But for now, knowing your local agricultural calendar and keeping windows closed during application are the first steps. Bottom line Dewayne Johnson was exposed to glyphosate at levels most people will never encounter, and a jury decided he deserved compensation. That outcome is not evidence that the oatmeal in your pantry is dangerous. But it is a reminder that the dose, the context, and the person doing the exposing all matter enormously. Glyphosate is a chemical tool with benefits, trade-offs, and genuine open scientific questions. Learning to hold that complexity without collapsing into panic or dismissal is, honestly, one of the most useful and hardest things to do in navigating modern health science.

German Health Minister Nina Warken and WHO Hub in Berlin highlight 2025 achievements
Germany’s Federal Minister of Health, Nina Warken, visited the WHO Hub for Pandemic and Epidemic Intelligence in Berlin today to review progress and launch its 2025 Annual Report. The report highlights advances in using artificial intelligence, data science and pathogen genomics to strengthen global preparedness for future pandemics.In 2025, the WHO Hub in Berlin worked with more than 160 Member States and over 190 partners to help countries and organizations develop new systems and tools to detect and understand new public health threats as quickly as possible, whenever and wherever they occur.BMG to confirm whether they wish to contribute a quote. “Detecting outbreaks early is one of the most effective ways to save lives and prevent epidemics from becoming global crises,” said Federal Minister of Health Nina Warken. “Germany is proud to host and support the WHO Hub for Pandemic and Epidemic Intelligence. Its work strengthens our safety at home and helps protect people worldwide.”Artificial intelligence is increasingly transforming the detection of outbreaks. In 2025, the Hub launched an upgraded version of the Epidemic Intelligence from Open Sources (EIOS) system, which uses enhanced AI functions to scan global online information in real time and help experts quickly identify unusual health events. The system is now used by 120 countries.To better anticipate health threats, countries need information beyond traditional health data. The Hub supports countries in implementing Collaborative Surveillance, which integrates data on climate, animals, travel, and population movement to provide a more comprehensive and real-time understanding of health threats.The Hub also expanded global access to pathogen genomics, which helps scientists detect new pathogens, such as viruses and bacteria, understand how they spread and how dangerous they may become. Through the International Pathogen Surveillance Network (IPSN), the WHO Hub in Berlin worked with 309 partners in 101 countries to expand access to these technologies.“We are in a new era of global health threats, and we need new tools to face tomorrow’s challenges,” said Dr Chikwe Ihekweazu, Executive Director of the WHO Health Emergencies Programme. “The WHO Hub in Berlin helps countries use data and technology more effectively so they can identify risks earlier and respond faster. No country can address these threats alone. Strong cooperation remains our best defence.”“Berlin offers an ideal environment for our work. We collaborate closely with world-leading institutions such as the Robert Koch Institute and the Charité Center for Global Health,” said Dr Oliver Morgan, Head of the WHO Hub for Pandemic and Epidemic Intelligence. “Germany has supported the WHO Hub since its establishment, and we are pleased to welcome Federal Minister Nina Warken to the Hub today. This strong partnership helps us advance innovation in pandemic and epidemic intelligence and better support countries to prepare for future health threats.”The Hub is expanding the use of advanced analytics and mathematical modelling to forecast how outbreaks may develop and to assess which response measures are most effective. Through its Collaboratory, the Hub connects modelers and analysts with governments to ensure their work addresses real public health needs. In 2025, the community grew to 1300 members from 50 countries and 200 institutions. An AI-powered pandemic simulator, currently in the prototyping phase, will help decision-makers compare outbreak scenarios and help identify effective disease control measures.

The surprising new ways bacteria spread without propellers
Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found to spread across moist surfaces by fermenting sugars and creating tiny fluid currents that carry them forward — a newly identified behavior researchers call “swashing.” In another study, a different group of bacteria was shown to control its movement using a microscopic molecular “gearbox” that can reverse direction like a biological snowmobile.

Scientists engineer bacteria to eat cancer tumors from the inside out
Researchers are engineering bacteria to invade tumors and consume them from the inside. Because tumor cores lack oxygen, they’re the perfect breeding ground for these microbes. The team added a genetic tweak that helps the bacteria survive longer near oxygen-exposed edges — but only once enough of them are present to trigger the change. It’s a carefully programmed biological attack that could one day offer a new way to destroy cancer.

Breakthrough CRISPR system could reverse antibiotic resistance crisis
Antibiotic resistance is racing toward a global crisis, with “superbugs” projected to cause over 10 million deaths annually by 2050. Now, scientists at UC San Diego have unveiled a powerful new CRISPR-based tool that doesn’t just fight resistant bacteria—it can actively strip away their drug resistance. Inspired by gene drives used in insects, the technology spreads a genetic “fix” through bacterial populations, even inside stubborn biofilms that shield microbes from antibiotics.
Oral bacteria may signal metabolic health and even contribute to obesity
It turns out your mouth may know more about your metabolism than your bathroom scale. New research shows that people with obesity host a distinct oral microbiome compared to individuals at a healthy weight. Rather than zeroing in on the gut microbiome, the study turns our attention to the mouth as a potential biological signal of metabolic health. It’s a shift that could challenge long-held assumptions about where obesity-related biomarkers can be measured.

Gut bacteria can sense their environment and it’s key to your health
Your gut is home to trillions of bacteria that constantly “sense” their surroundings to survive and thrive. New research shows that beneficial gut microbes, especially common Clostridia bacteria, can detect a surprisingly wide range of chemical signals produced during digestion, including byproducts of fats, proteins, sugars, and even DNA. These microbes use specialized sensors to move toward valuable nutrients, with lactate and formate standing out as especially important fuel sources.

Scientists Warn: This “miracle cure” works only by damaging human cells
MMS has long been promoted as a miracle cure, but new research shows it’s essentially a toxic disinfectant. While it can kill bacteria, it only works at levels that also damage human cells and beneficial gut microbes. Scientists warn that homemade MMS mixtures are especially dangerous due to wildly inconsistent dosing. The study calls MMS a clear case where the risks are high—and the benefits are effectively zero.
