Microscopy technique makes finer images of deeper tissue, more quickly July 7, 2021MIT To create high-resolution, 3D images of tissues such as the brain, researchers often use two-photon microscopy, which involves aiming a high-intensity laser at the specimen to induce fluorescence excitation. However, scanning deep within the brain can be difficult because light scatters off of tissues as it goes deeper, making images blurry. Two-photon imaging is also time-consuming, as it usually requires scanning individual pixels one at a time. A team of MIT and Harvard University researchers has now dev...

Read Article The term “labor shortage” was Googled more in May than at any other point in the search engine’s history going back to 2004.
