A Single 10-Second Kiss Can Transfer 80 Million Bacteria

Kissing is disgusting: A poorly choreographed ritual of bad breath, awkward eye contact, and slobbery after-drool. Now, to make it even worse, a new study from the Netherlands has determined how many cooties move from one mouth to another during your basic smooch. And it’s A LOT.


This 3D Printer Produces Biopolymers From Orange Juice And Bacteria

3D printers can make all sorts of great things, but they don’t do it out of thin air. First, there’s the model and then there are the materials. In most cases this is some sort of thermoplastic that can be heated and squirted from the printer’s head. But 3D printers don’t have to be the mechanical, polymer-ejecting gadgets we’re familiar with. What if all you needed was some genetically-modified bacteria and orange juice?


Magnetic Nanobeads Can Snatch Bacteria And Virus Out Of Blood

Sepsis is an nasty and surprisingly common way to die. The illness is triggered by blood infections but, ultimately, it’s your own immune reaction — not the bacteria or virus — that poisons you to death. Filtering those pathogens out of blood right away, though, could be a promising treatment. Enter a new device made of magnetic nanobeads coated in sticky proteins that attract bacteria, viruses, and fungi.


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.
