Two-photon microscopy (also known as two-photon fluorescence light microscopy) was invented in 1990 as a new method of imaging live cells and tissues in three-dimensions. Conventional fluorescence microscopy illuminates a specimen through the processes of excitation and emissions.
According to a recent Northwestern Medicine study, hair follicle stem cells also turn rigid with age, making it harder for them to generate hair, just like people’s joints can stiffen and become more difficult for them to move around.
Conventional implantable medical devices designed for brain stimulation are often too rigid and bulky for what is one of the body's softest and most delicate tissues.
Mount Sinai researchers have solved a major mystery in cancer research: How cancer cells remain dormant for years after they leave a tumor and travel to other parts of the body, before awakening to create metastatic cancer.
Advancing our understanding of the human brain will require new insights into how neural circuitry works in mammals, including laboratory mice.
Designing a vaccine starts with finding the right ingredients. Every infectious agent has molecules, called antigens, that the immune system could potentially recognize and attack. So scientists must carefully consider which antigens should go into a vaccine.
When neurons fire an electrical impulse, they also experience a surge of calcium ions.
Retina is the only part of the central nervous system that can be visualized noninvasively with optical imaging approaches.
Using electrodes smaller than a human hair, researchers are able to connect mind to machine and interact with the human brain in revolutionary ways.
