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.

Three-Dimensionally Reconstructed Kidney Glomerulus Simulates Structural and Functional Characteristics In Vitro

A 3D engineered kidney glomerulus model replicates structural and mechanical features of the glomerular filtration barrier, enabling the study of podocyte-related diseases and drug screening with improved physiological relevance.

New Neural Circuit Discovery Explains Precision Steering in Fruit Flies

When a fruit fly is navigating straight forward at high speed, why does it know that it's not straying off course? Because as long as the fly moves directly forward, the visual scene shifts from front to back in a near-perfect mirror image across both retinas – generating, in other words, a symmetrical visual motion pattern.

New Imaging Technique Offers Clearer View of Brain Function

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases.

New mosTF Microscopy System Enhances Real-Time Brain Plasticity Research

The brain's ability to learn comes from "plasticity," in which neurons constantly edit and remodel the tiny connections called synapses that they make with other neurons to form circuits.

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.

New two-photon microscope provides unprecedented brain-imaging ability

Advancing our understanding of the human brain will require new insights into how neural circuitry works in mammals, including laboratory mice.

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.
