Watch plant roots grow in extreme close-up 3D
You've probably never seen growing plants this way before. A team of researchers from the Institute of Science and Technology in Austria have filmed Arabidopsis thaliana (a flowering weed) roots as they grew in extreme close-up 3D. The team did so to demonstrate a method they developed that uses a microscope with lasers and fluorescent lights to automatically track moving minuscule objects invisible to the naked eye. They also used a special lighting system to keep the plants alive during the whole process, so the setup can capture the roots' cells as they grow and split.
