Improving imaging resolution of the brain

Improving imaging resolution of the brain
Nowadays, characterisation of biological processes necessitates investigation at the single molecule level, and hence sensitive imaging techniques. To achieve this, a European team used nanoparticles as imaging probes for receptors in the brain. In the nervous system, neurons communicate with each other or with other cell types through specialised structures known as synapses.

MRI technique enables consistent diagnoses

MRI technique enables consistent diagnoses
A technology harnesses imperfections that typically compromise MRI exams to create images resolved enough to enable consistent diagnoses across populations for the first time. These are findings of a study led by NYU Langone Medical Center and published in Nature Communications. Since its emergence in the 1970s, MRI has given physicians a better look inside tissues, helping to diagnose maladies from brain tumors to internal bleeding to torn ligaments.

Handheld device captures images with cellular resolution

Handheld device captures images with cellular resolution
  Engineers and physicians at Duke University have developed a handheld device capable of capturing images of a retina with cellular resolution. The probe will allow researchers to gather detailed structural information about the eyes of infants and toddlers for the first time.

SPR devices detect molecules within a few hundred nanometres

Surface Plasmon Resonance (SPR) devices are the benchmark in optical sensing. They are used for detecting biomarkers of disease, discovering drugs, analysing chemicals, ensuring food quality and safety, and detecting pollutants in our environment. SPR devices can detect molecules within a few hundred nanometres of their metal surfaces.

Enabling the visualisation of oxygen in tissue

Enabling the visualisation of oxygen in tissue
Learning how to look inside a body without having to cut it open is still an important part of medical research. One of the great challenges in imaging remains the visualisation of oxygen in tissue. A team led by Prof. Vasilis Ntziachristos, Chair for Biological Imaging at the Technical University of Munich (TUM) and Director of the Institute for Biological and Medical Imaging at the Helmholtz Centre in Munich, has developed an approach to this task.

Imaging technique reveals brain tissue at multiple scales

Imaging technique reveals brain tissue at multiple scales
  MIT researchers have developed a technique for imaging brain tissue at multiple scales, allowing them to peer at molecules within cells or take a wider view of the long-range connections between neurons.

Minimally traumatic and inexpensive ceramic laser scalpel

Scientists from MIPT and their colleagues have developed a compact and powerful ceramic-based laser with applications in minimally traumatic and inexpensive laser surgical scalpels, and also for cutting and engraving composite materials. The results of the study have been published in Optics Letters. Today, lasers are in consumer electronics devices, medicine, metallurgy, metrology, meteorology, and many other areas.

Google Glass could help autistic children read emotions

Google Glass could help autistic children read emotions
Like many autistic children, Julian Brown has trouble reading emotions in people's faces, one of the challenging conditions of the neurological disorder. Now the 10-year-old San Jose boy is getting help from an experimental device that records and analyses faces in real time and alerts him to the emotions they're expressing. The facial recognition software was developed at Stanford University and runs on Google Glass, a computerised headset with a front-facing camera and a tiny display just above the right eye.

Multiphoton microscope speeds up disease diagnosis

Multiphoton microscope speeds up disease diagnosis
Two optical devices could reduce the need to take tissue samples during medical examinations and operations and to then send them for testing – potentially speeding up diagnosis and treatment and cutting healthcare costs. One is a lightweight handheld microscope designed to examine external tissue or tissue exposed during surgery. One example of its use could be to help surgeons compare normal and cancerous cells (during an operation).
