1. Scientists create 3D-printed microscope for low-resource settings This article discusses a new 3D-printed microscope developed by scientists from the University of Edinburgh in Scotland. The microscope is designed for use in low-resource settings and is made from plastic and off-the-shelf components. It is low-cost, easy to assemble, and can be used to identify bacteria and parasites, making it a valuable tool in the fight against disease. It could also be used in the classroom to help teach students about the basics of microscopy. 2. A new microscope gives scientists the power to see at the nanoscale This article discusses a new type of microscope developed by scientists at the University of Cambridge. The microscope is capable of resolving features down to a nanometer scale, allowing scientists to view objects and phenomena at a much smaller level than ever before. It could have applications in the fields of biomedicine, drug design, and materials science. 3. Scientists develop a microscope that can see inside the brain This article discusses a new type of microscope developed by scientists at the University of California, Berkeley. The microscope is capable of imaging the brain at a much higher resolution than conventional methods, allowing scientists to
In fossil leaves, puzzling structures are often visible under the microscope. Researchers have now been able to show for the first time that they originate from calcium oxalate crystals. On the one hand, their discovery facilitates the identification of the ancient plant remains. But it also provides answers as to how the ability to form such crystals arose and what function they presumably perform.
50 million years ago in what is now northwestern Colorado, a katydid died, sank to the bottom of a lake and was quickly buried in fine sediments, where it remained until its compressed fossil was recovered in recent years. When researchers examined the fossil under a microscope, they saw that not only had many of the insect's hard structures been preserved in the compressed shale, so had several internal organs and tissues, which are not normally fossilized.
