Researchers Demonstrate Technique To Give Us Better Understanding of Human Tissues
06/06/2012 - 11:36

Research from North Carolina State University demonstrates that a relatively new microscopy technique can be used to improve our understanding of human tissues and other biomedical materials. The study focused specifically on eye tissues, which are damaged by scarring in diabetic patients.

Sharp images from the living mouse brain
02/06/2012 - 07:53

Using the STED microscopy developed by Stefan Hell's team, the scientists have, for the first time, managed to record detailed live images inside the brain of a living mouse. Captured in the previously impossible resolution of less than 70 nanometers, these images have made the minute structures visible which allow nerve cells to communicate with each other. This application of STED microscopy opens up numerous new possibilities for neuroscientists to decode fundamental processes in the brain.

New imaging method sheds light on cell growth
08/26/2011 - 08:50

University of Illinois researchers are giving a light answer to the heavy question of cell growth. Led by electrical and computer engineering professor Gabriel Popescu, the research team developed a new imaging method called spatial light interference microscopy (SLIM) that can measure cell mass using two beams of light. Described in the Proceedings of the National Academy of Science, the SLIM technique offers new insight into the much-debated problem of whether cells grow at a constant rate or exponentially.

Microscopes borrow tricks from astronomy to see deep into living tissues
07/27/2011 - 06:40

Researchers at the University of California, Santa Cruz, are developing new microscope technologies to enable biologists to see deep within living tissues and observe critical processes involved in basic biology and disease.  Principal investigator Joel Kubby, an associate professor of electrical engineering in the Baskin School of Engineering at UCSC, has worked on adaptive optics (AO) systems for large telescopes as well as for biological imaging. In astronomy, AO systems correct the blurring of telescope images caused by turbulence in the Earth's atmosphere. In microscopy, blurring is caused by the flowing cytoplasm of living cells.
