To use a light microscope to examine animal or plant cells. To make observations and draw scale diagrams of cells. Turn the coarse focus so that the stage is as close to the objective lens as ...

Dr. James Lim, associate professor of pediatrics at UBC’s faculty of medicine, observes pediatric cancer cells grown in a chicken egg under a microscope.

The researchers observed that light activated the enzyme, causing predictable cell movements. For example, specific light ...

Scientists need sharp tools to peek into the tiny world of biology, and fluorescence microscopy has been a game-changer ...

Life takes shape with the motion of a single cell. In response to signals from certain proteins and enzymes, a cell can start to move and shake, leading to contractions that cause it to squeeze, pinch ...

The research team achieved this by targeting all the proteins in the cell with small molecules that subsequently link up with other compounds under light to produce large ... A standard benchtop ...

then began to produce light-sensitive GEF enzymes on their own. In experiments, the researchers then placed each enzyme-infused egg cell under a microscope and shone light onto the cell in ...
