What your gut bacteria are quietly telling your immune system
By Elena Marsh · 7 min read
Gut bacilli, dark-field microscopy at 1,000× · Marsh Lab

The intestinal microbiota constitutes a dense and metabolically active community that has co-evolved with its human host over millennia. Trillions of bacteria, viruses and fungi line the gut wall, and the balance between them shifts with every meal, illness and course of antibiotics.

For decades these microbes were treated as passive passengers. That view has collapsed. A wave of studies now frames the gut as an organ in its own right — one that files reports to the brain, the liver and the immune system in a language of small molecules.

Microbial metabolites modulate host immune responses through direct interactions with intestinal epithelial cells and resident immune populations, tuning how aggressively the body reacts to threats.

“The gut is not a passive tube — it is in constant conversation with the rest of the body.”

Short-chain fatty acids, produced when bacteria ferment dietary fibre, are among the clearest messengers. They calm inflammation, reinforce the gut lining and appear to shape the behaviour of immune cells far from the intestine itself.

Disruptions to this community — through poor diet, stress or repeated antibiotics — have been linked to conditions ranging from allergies to autoimmune disease. Researchers caution that correlation is not yet cause.

Newer work suggests these signals reach well beyond digestion, shaping metabolism, sleep and even mood, and pointing toward a future of microbiome-guided medicine.

The role of the gut microbiome in human health

Dr. Nadia OseiResearch editor · July 21, 2026

Trillions of bacteria live in the human gut, and the past decade of research suggests they do far more than digest food.

The intestinal microbiota constitutes a dense and metabolically active community whose composition varies substantially across individuals, diets, and disease states. Microbial metabolites modulate host immune responses through interactions with intestinal epithelial cells and systemic signaling pathways.

Fig 1. Relative abundance of short-chain fatty acid producers across the study cohort.

These findings suggest that targeted modulation of the microbiota may represent a viable therapeutic avenue, though causal mechanisms remain incompletely characterised.

We are only beginning to read the chemistry these organisms write.

Next week: what happens to that chemistry when antibiotics arrive, and how long the community takes to recover.

Winter power prices, charted

Tomas LindqvistData desk · July 16, 2026

Household electricity costs followed a familiar seasonal arc this year, and one month stood far above the rest.

Jul · Sep · Oct · Dec · Jan · Mar · May

Analysts expect the pattern to soften next year as storage capacity comes online, though winter demand remains the dominant factor.

Electricity prices climb through winter in this chart. The January peak sits about 40 percent above the summer low, then eases into spring.

The loop

One gesture at the front. A memory behind it.

Most tools stop at the answer. Lensable treats every selection as the beginning of something you’re working on — so what you looked at on Tuesday is still working for you in October.

Coming soon Saved Highlights, followed topics and the weekly brief ship together in the next Lensable build. Everything else on this page works in the beta today.

Answers you can find again.

Every explanation keeps the thing that made it: the selection, the page, the URL, the date, the model that answered. Saved Highlights is research memory, not a bookmark folder — searchable the same way you’d ask a question.

FAQ

Short answers, honestly given.

More on the full FAQ page, or ask us directly via support.

What is Lensable?

A Chrome extension that lets you outline an object or select an area on any webpage, then find products or ask the AI of your choice about what you selected.

How does selection work?

Hover to outline the object under your cursor, or draw a box with Square Select. Click to lock the selection, then choose to search for products or ask an AI about it.

Does it work on YouTube?

Paused video is supported where technically possible. DRM-protected video can't be captured, those frames come back blank on purpose.

Can it find the exact product?

Sometimes. Results are grouped into likely exact matches, similar items, deals and used listings, but identification is best-effort, never guaranteed. Always confirm the item and price on the seller's site.

Which AI providers are available?

Lensable Auto (default routing), ChatGPT, Claude, Gemini, Grok and Perplexity. You pick per question, or let Auto decide.

Does Lensable send screenshots to AI providers?

Only when you ask. The selected area and your question are sent to the provider you chose to generate the answer. Lensable doesn't continuously capture your screen. See the AI disclosure.

What permissions does the extension need?

It asks for access to the active tab, scripting, storage, identity (sign-in) and an offscreen document, with site access so selection can work on the pages you use it on. Each one is explained on the permissions page.

How is usage counted?

Each plan includes a monthly amount of Lensable use. Scanning a page and making or adjusting a selection never counts against it — usage applies only when you run a lookup or ask a question. Features cost different amounts to run, so a product lookup draws more from your monthly usage than a quick highlight explanation. Your remaining usage is shown in the extension.

Can I cancel my subscription?

Yes — Lite, Pro and Power are subscriptions and can be cancelled anytime from Manage billing in the extension or your account page, which opens the secure Stripe billing portal; you keep access for the remainder of the paid period. The Free plan needs no cancellation.

Which browsers are supported?

Desktop Chrome. Other Chromium-based browsers may work but aren't officially supported yet.

Why might a result be inaccurate?

Product matching and AI answers are probabilistic: image quality, cropping, catalog coverage and model limitations all affect them. Treat results as leads to verify, not facts.

How do I report a problem?

Email support@lensable.ai or use the support page. A screenshot of what went wrong helps a lot.

How do I delete my data?

Follow the steps on the delete data page: email us and we'll remove what we hold, typically within 30 days. Uninstalling the extension stops all capture immediately.

Understand more of what you see.

Lensable is in early beta for desktop Chrome. The Chrome Web Store listing isn't live yet, beta builds are installed manually, and it takes about a minute.

Watch demo

We'll email you the beta build with one-minute install steps.
