All you have to do is get them into your inner eye and let them paddle around a bit.
Kirk's just steamed that we've already figured out a cooler space suit than his.
Single-celled creatures on the lam, beware! Scientists have devised a method utilizing ultrasounds to hold small bits of matter (including living cells) by seemingly invisible means. The technique, called "acoustic tweezers," appears in the current issue of the Proceedings of the National Academy of Sciences.
Personally, I'm still amazed by how small mini M&Ms are, but scientists and engineers have higher aspirations, so they went ahead and built a steam engine the size of a water droplet in fog, which is a few micrometers wide.
You may have heard that every snowflake is unique, but to really get a sense of that you've got to dig down to the microscopic level. That's exactly what the folks over at the Beltsville Agricultural Research Center in Maryland did with a Low Temperature Scanning Electron Microscope (or LT-SEM). The result? A look at the structure of snow crystals in all shapes and configurations. Some of them even look like alien architecture from a distant world. Check it out in the gallery below — the shapes just get crazier and crazier. After all, we're all not tired of snow just yet, right?
Ever wonder what's inside that little chip that powers your computer and makes life worth living? To find out, all you need is an old Pentium III, a power saw, a scanning electron microscope and one curious PhD student's step-by-step guide on where to start.
