Switzerland Puts Secret Bacteria In Cheese To Catch Knockoffs

In parts of Europe, where cheese is taken seriously as a source of national pride, entire labs are devoted to spotting knockoff Emmental and Gruyere. Switzerland has what may be the most impressive strategy yet: secret cocktails of bacteria, sent only to licensed cheesemakers, that work as living biological tracers.


A Gut Microbe Could Be The Key To Stopping Peanut Allergies

In the past few decades, food allergies have been increasingly and mysteriously on the rise. A possible explanation lies with our gut bacteria, which have been reshaped by our soap-laden and antibiotics-laden lifestyles. A new study in mice adds intriguing evidence: one particular type of bacteria prevents sensitivity to peanuts.


We Only Just Discovered This Super-Common Virus That's Probably Inside Of You

Today, scientists report the discovery of an incredibly common new virus that lives inside human gut bacteria. It’s called crAssphage (more on the name later!), and it’s about six times more abundant than all other known bacterial viruses put together. How did we miss it for so long?


Electricity-Eating Bacteria Are Real And More Common Than We Thought

In the extreme world of bacteria, stunts such as living in hot springs or without oxygen are, like, totally unimpressive. But then there are bacteria that live off electricity, feeding directly on naked electrons. Even more surprisingly, scientists are finding that these bacteria are not even that rare.


Why The First Antibiotic-Resistant Superbug Found In Food Is A Big Deal

In very bad news, a superbug resistant to last-resort antibiotics was found in imported squid, according to a report this week. This is a scary development in antibiotic resistance — even if you don’t eat squid. Here is why one small finding has frightening implications.


SpaceX Is Sending Dinosaur Microbes To The Space Station

The SpaceX Dragon capsule that recently left Earth for the International Space Station is carrying many an important item: a new laser communication system, coffee (which they just ran out of!), a planter for fresh produce, and billions and billions of microbes swabbed from dinosaur bones, sneakers, and spacecraft clean rooms. Over the next few days, we’ll find out how well these bacteria grow in space.


4 Ways Tiny Microbes Changed Life On Earth Forever

This is the microbes’ world — we just live in it. Throughout the history of Earth, microbes have radically reshaped life on the planet, from creating the very air we breath to wiping out almost all life on Earth. Don’t underestimate the power of tiny, tiny microbes populating the Earth trillions of times over.


Concrete-Dissolving Bacteria Are Destroying Our Sewers

Underground in places nobody likes to look, bacteria are doing terrible things to our sewage pipes. The concrete pipes that carry our waste are literally dissolving away, forcing engineers into a messy, expensive battle against tiny microbes.


This Pretty Gel Is A Smart Tag That Changes Colour When Food Spoils

Thanks to what looks like a little square of jello, you could tell your milk has gone bad without even opening the (gross-smelling) container. The gel is actually a nanorod-embedded smart tag that changes from red to green, mimicking the growth of bacteria in milk without touching it.


Why Do Bacteria Thrive In Space?

For reasons that still aren’t well understood, bacteria proliferate in microgravity. Creating a potential recipe for disaster for humans stationed in space for long periods, bacteria’s love of low-g also raises an intriguing question: Why are they so comfortable there?
