A new microscopy method that ditches lenses altogether could create the highest-resolution images ever seen. The system reconstructs an image from the electron waves scattered by a sample, and has no fundamental experimental limits imposed by constraints like blurry glass or wavelengths of visible light. It can even be used to image live cells without harming them.
Ohio State University researchers have captured the first-ever images of atoms moving within a molecule using a novel technique that turns one of the molecules own electrons into a kind of flash bulb. The technique has yielded a new way of imaging molecules, but could one day help scientists to intimately control chemical reactions at the atomic scale.
A soybean-shaped bacterium called Caulobacter crescentus, found in freshwater and seawater, makes one of the strongest adhesives in the world. Now high-resolution video microscopy is shedding light on how it can carefully use this adhesive, like a super-precise application of superglue, to stick on surfaces in wet environments.
Proteins are like the workhorses of genetic biology, but they can be notoriously difficult to study. Their structure has everything to do with their function--and sometimes dysfunction--which has far-reaching implications in health and medicine.
A new real-time view of immune cells attacking the pancreas sheds light on how type 1 diabetes unfolds, as white blood cells seek out and destroy insulin-producing beta cells. Researchers believe it could help point the way to new intervention methods to halt the destruction before the onset of type 1 diabetes, also known as juvenile diabetes.
Scientists use mice for all kinds of fun things, from injecting old mice with young mouse blood to training them to sniff for bombs, but when doing research, it's often very difficult to see what's actually going on in a mouse's brain.
Researchers at Imperial College London and the University of Oxford have pioneered a new technique to see exactly how our body's "natural killer" white blood cells actually do their dirty work. It's the first time we've ever been able to see how this element of the body's natural defenses actually works.
We've seen single-molecule "motors" before, but they're pretty primitive, motors only in the most basic sense of the word. But this new one, made of a single butyl methyl sulfide molecule, is much closer to what images the word "motor" might conjure: when electricity is applied, the molecule is triggered to spin, without affecting any other molecules around it.
Researchers at UCLA have built a cheap, optics-free holographic microscope capable of detecting bacteria like E. coli in things like water, food, and blood. And by cheap, we mean really cheap. The researchers say it costs less than $100 to build.
All the new breakthroughs in microscopy we’ve seen recently are designed to help scientists see deeper, inside individual cells and into the depths of the brain. Of course, this would be easier to do if there wasn’t a bunch of other tissue blocking the cells you want to see.
A new type of X-ray microscope — or more appropriately, nanoscope — is another big breakthrough in the world of imaging the small. It computes images rather than glimpsing them directly, allowing scientists to see details at the nanoscale.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
