The only thing cooler than a being an astronaut who gets to explore nearby worlds would be to one day land on a planet completely made of delicious chocolate. It hasn’t happened yet, but students at Johns Hopkins University put melted and solid chocolate under a powerful electron microscope, and it’s remarkable how…
Not even squinting will help you see this image without the help of a microscope. This is the smallest inkjet-printed colour image ever produced, and it’s the same size as a single pixel on a Retina display.
To the naked eye, your body may not look like the site of much action, but take a closer look and you'll see the microscopic battles being waged every moment of every day, between our bodies' invaders and the systems that fight back.
Even a perfectly smooth human hair looks like a scaly, alien creature under a microscope. Zoom in on this particular hair, though, and you'll find something even stranger: a teeny, tiny comic strip called "Juanita Knits the Planet."
Getting microscopic objects into formation is a tricky proposition. They don't make tweezers small enough. Fortunately there's an alternative: sweeping them up in a sonic vortex.
Researchers at MIT have discovered that when nanowires just billionths of a meter thick are inserted into liquids, they passively draw it upwards along its length without any outside power or suction. It's like the world's tiniest Dyson that you never have to find an outlet to plug in.
Stare hard at this photo. Stare really hard. Can you guess what you're looking at? No? Maybe because your eyes aren't working hard enough? Maybe you should squint your eyes? Okay. It's your eyeballs. Your amazing, microscopically-structured eyeballs. Squint harder!
This is a picture of two cancer cells splitting and dividing to become four cancer cells. Even though it looks stunning, I hate it. To think that those little clouds and wisps have so much power is just terrifying.
Forget nanobots. Who needs 'em? Since apparently we can now directly control live bacteria, and make them do our bidding. I'm in awe.
It might look kinda grey and boring, but the tiny ring in that image is a world-beater: it measures just five microns across, and is only 300 nanometers thick. That's very, very tiny indeed. So, it won't be going around anyone's finger as a symbol of undying love... but it may be a key component in single-photon…
