Scientific Reports, Published online: 15 September 2026; doi:10.1038/s41598-026-69567-3 A prospective randomized controlled pilot study of gut microbiome modulation by Nigella sativa seed oil and thymoquinone metabolism in healthy volunteers: implications for gastrointestinal surgery

Ancient DNA reveals that plague was already killing hunter-gatherers in Siberia 5,500 years ago, long before cities and flea-driven epidemics. The prehistoric strains may have been especially dangerous because they carried a genetic factor capable of provoking severe immune reactions.

“With IBD, and with other many diseases that we collaborate with other groups to study, there [are] some treatments, but maybe those treatments still are not maybe the best or the most targeted that we can do because we … fundamentally don’t understand the disease fully.” With its black casing, grey hoses and a plethora […]

Introducing the next-gen chromogenic culture medium designed for rapid detection isolation and enumeration of Pseudomonas aeruginosa in water samples Delivers precise countable red colonies from just 18 to 24 hours

When public health researchers want to know whether diseases such as COVID-19 or polio are circulating in a community, they can look for genetic evidence in wastewater. Entomologist Dana Price wondered whether the same principle could be applied to mosquitoes. The question led to an unconventional experiment."What we did, colloquially, was build a mosquito toilet," said Price, an associate profes…

Male fathead minnows exposed to a common wastewater pollutant became fiercer rivals and poorer parents in a rare whole-lake experiment. The findings reveal how hormone pollution can reshape animal behaviour and affect entire populations in ways laboratory studies may not predict.

Simulating 30 Million Microbes in the Browser WebGPU gives the browser direct access to modern GPU capabilities — not just for rendering, but also for general-purpose computation through compute shaders. But how far can we actually push it? What happens if, instead of running a small compute demo, we try to build a full simulation with tens of millions of active objects? That is what I wanted to …

In the push to establish a human presence on Mars, agriculture will play a pivotal role—not just for food production but as part of life support systems that recycle air, water, and waste. Yet any biological system introduced to the Martian environme

BackgroundAcute graft-vs.-host disease (aGvHD) is a life-threatening complication of allogeneic hematopoietic cell transplantation (allo-HCT), where allogeneic donor T cells recognize recipient tissues as foreign and damage them. Gut microbiota disruption following allo-HCT has been associated with increased aGvHD incidence, severity, and mortality. Growing clinical evidence suggests the efficacy…

Pneumococcal bacterial subtypes influence how air pollution affects invasive disease risk, with certain strains linked to greater or faster risks of pneumonia, sepsis, and meningitis.

[Nature Biotechnology] Microbial symbiosis drives the functional and phylogenomic diversification of life on Earth yet remains underexplored because of culturing challenges. This study used machine learning (ML) to predict symbiotic […] The post A Genomic Catalog Of Earth’s Bacterial And Archaeal Symbionts appeared first on Astrobiology .

[Nature Sensors] Deep sea microorganisms remain largely inaccessible because existing sampling and cultivation methods fail to preserve native high-pressure microenvironments from seafloor to laboratory. Here we show a closed-loop cyber […] The post Closed-loop In Situ Isolation Of Deep-sea Extremophiles Through Sensor-driven Microenvironment Preservation appeared first on Astrobiology .

Nature, Published online: 11 September 2026; doi:10.1038/d41586-026-02901-x Traces of the psychoactive compound arecoline suggest that two people regularly sucked on psychoactive betel nuts. Plus, what motivates people to take action on climate change and the promise of nasal vaccines.

Driven by the ongoing environmental issues caused by plastics, biodegradable plastics, synthesized by microorganisms and naturally decomposed, are drawing significant interest.

BackgroundTicks of the genus Hyalomma are among the most important vectors of pathogens affecting humans and animals in arid and semi-arid regions of Eurasia. Recent environmental changes, including climate warming, increasing aridity, and livestock movements, may influence the distribution of Hyalomma species into previously unrecorded areas. However, information on the current distribution of t…

BackgroundCanine otitis externa provides a chronic, inflamed and frequently antimicrobial-exposed niche in which Pseudomonas aeruginosa can persist through a coordinated repertoire of adhesion, biofilm, iron-acquisition, secretion and toxin systems.MethodsWe characterized the virulence-associated genomic architecture of a historical Hungarian collection obtained from canine otitis cases in 2010 a…
