Two photon Microscopy News and Research

RSS

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.

Uncovering the Neural Basis of Goal-Directed Navigation in Fruit Fly Brains

When we walk down the street, we have an internal sense of which way we are heading, from looking at street signals and physical landmarks, and also a sense of where we'd like to go.

Hair Regrowth with Softening Stiff Hair Follicle Stem Cells with microRNA

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.

High-Resolution, Stable Brain Stimulation by Ultraflexible Nanoelectrodes

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.

Scientists find how cells remain dormant for years before awakening to create metastatic cancer

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.

Scientists identify antigen valencies that work best in vaccine designs for HIV, SARS-CoV-2

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.
