Researchers Observe Cell Polarity Using Advanced Microscopy

Over the past several years, Rong Li, Ph.D., at the Stowers Institute for Medical Research has been making crucial discoveries about the development of cell polarity—the process by which one side of a cell becomes different from the other side. Such polarity is critical for the functioning of the vast majority of cells.

Improved Biological Imaging Using Three-Photon Microscopy

Scientists may be a step closer to cracking one of the world's most compelling mysteries: the impossible complexity of the brain and its billions of neurons. Cornell researchers have demonstrated a new way of taking high-resolution, three-dimensional images of the brain's inner workings through a three-fold improvement in the depth limits of multiphoton microscopy, a fluorescence-based imaging technique with Cornell roots.

Microscopic Study Provides New Insights into Cell Division

Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the current issue of the Journal of Cell Biology.

UCLA Creates Optical Microscope to Directly View Nanoscale Objects

By using tiny liquid lenses that self-assemble around microscopic objects, a team from UCLA's Henry Samueli School of Engineering and Applied Science has created an optical microscopy method that allows users to directly see objects more than 1,000 times smaller than the width of a human hair.

Nanoscale Gears Generate Large Forces Inside Cells

To live is to move. You strike to swat that irritable mosquito, which skilfully evades the hand of death. How did that happen? Who moved your hand, and what saved the mosquito? Enter the Molecular Motors, nanoscale protein-machines in the muscles of your hand and wings of the mosquito. You need these motors to swat mosquitoes, blink your eyes, walk, eat, drink... just name it. Millions of motors tug as a team within your muscles, and you swat the mosquito. This is teamwork at its exquisite best.
