The fastest camera ever made can automatically count individual cells, processing millions of images continuously and doing it 100 times faster than existing light microscopes. This super-fast imaging system could potentially detect cancer cells lurking in millions of healthy cells, and could lead to speedier diagnosis of disease.
The new iPad's screen is apparently so amazing it can't be described in words (though we're certainly going to try; look for our review early next week). But images can sometimes tell the story more effectively, anyway. Lukas Mathis over at Ignore the Code stuck the new iPad, as well as about a dozen other gadgets, under a microscope to check out what the pixels look like way up close, at 80x magnification.
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.
Despite all the huge advances in medical technology in the past couple centuries, petri dishes, one of the most crucial pieces of equipment, haven’t changed much at all. Now a grad student at Caltech has finally brought these flat-bottomed bowls into the 21st century.
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.
