Some IUDs get removed for pain, bleeding, or inflammation, so we took a look at what was actually living on the strings. Symptomatic removals showed a higher overall bacterial load and a tilt toward non-Lactobacillus taxa, while asymptomatic removals stayed comparatively low-key. Lactobacillus did not disappear, but it also was not running the show alone. Same device, different microbial crowd. The takeaway is simple: the IUD string is an active host–microbe interface, not a passive piece of plastic.
Kentucky Microbiome Map and Dataset
This dataset and interactive map expose Kentucky’s environment as a living system—tracking microbes, water quality, and landscape conditions across space instead of pretending health risks stop at county lines. Together, they turn raw field data into something you can see, explore, and interrogate, showing how geology, biology, and human activity overlap in ways that directly matter for public health, environmental risk, and real-world decision making.
This paper tears into traditional geohealth—the raw, sometimes uncomfortable reality that the geology around us can quietly shape disease risk, environmental exposure, and community resilience. Using Kentucky’s karst landscapes, legacy mining, flooding, radon, and microbial ecosystems as case studies, it shows how Earth systems, biology, and human health collide—and why understanding the ground beneath us isn’t academic curiosity, it’s survival science.
Pig Sertoli cells just casually survive human complement attacks with no immunosuppressants — so we asked: what’s their secret? Turns out, these testicular legends rewire their gene expression when exposed to human serum, flipping switches on immune regulation, survival, and accommodation pathways. We found 62 genes throwing down in response and spotlighted key players like CCL2 and A20. Bonus: this xenograft survival story was so badass, it landed the cover.
Turns out popping a single-species probiotic for 30 days doesn’t shake up your gut party if you’re already healthy—microbiomes stayed chill, no matter the pills. This preliminary data suggests your Bifidobacterium supplement might just be taking a scenic ride through your system without leaving much of a trace.
Skip food for 24 hours and your body doesn't just grumble—it starts making biochemical power moves. In this study, intermittent fasting dropped TMAO levels (a known CAD villain), shifted over two dozen metabolites, and triggered short-term changes in amino acids and urea that hint at metabolic reprogramming. Sure, things bounce back after you eat, but this data suggests even brief fasting hits the system like a dress rehearsal for long-term health gains, reduced disease risk, and maybe even a longer, sharper life.
