It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

3D microscopes do already exist, but they work slowly and give poorer results. The most common type works by recording pixel after pixel in series, which are then assembled into a 3D image. This takes ...

To get a better look at brains, Harvard researchers are making microscopes work more like human eyes. Subscribe to our newsletter for the latest sci-tech news updates. Until recently, the quest to ...
