New robust and rapid approach that simplifies polarimetric measurements published by the Côté laboratory
Members of the Neurophotonics Centre have published a new robust and rapid approach to simplify polarimetric measurements in second-harmonic generation, two-photon excited fluorescence and coherent anti-Stokes Raman scattering. The technique consists of adding a second properly oriented compensation dichroic to negate any scrambling of the polarization by polarimetric microscopy.
A team lead by Frédéric Leblond, Professor at Polytechnique Montréal, and Kevin Petrecca, Chief neurosurgeon at the McGill University Health Centre, with collaborators at the Montreal Neurological Institute, McGill University and the MUHC has developped a new probe that can detect cancer cells in the brain with a precision higher than the existing technology.
The probe, which works by Raman spectroscopy, can detect cancer cells that are not detectable by Magnetic Resonance Imaging (MRI).
Dr. Robert Campbell, from the University of Alberta, recently published an article in Nature Methods in which he describes novel biosensors that change color in response to specific biological event.
The ACFAS - Association francophone pour le savoir is holding its annual scientific image contest, and the prize for the 2015 International Year of Light will be awarded to images that illustrate the nature of light or the interaction between light and matter. Researchers are invited to submit their images by January 26th 2015. All the details are on the ACFAS website: Concours preuve par l'image 2015.
Researchers Armen Saghatelyan, Paul and Yves De Koninck and Daniel Côté were recently featured on "Découverte", the scientific television show presented by Radio-Canada. The researchers explain the possibilities and promises of new neurophotonics approaches and technologies to better understand the brain, leading to major scientific breakthroughs.

The Neurophotonics Centre hosted the Launch meeting for the Canadian Neurophotonics Platform on December 16-17 2014 in Québec city. The platform aims to develop, test and promote new neurophotonics tools using the power of optics and and photonics to serve research in neurosciences and the brain.
The lauch meeting was a great opportunity for platform members and important collaborators to prioritize the objectives and goals of the new platform. You can read the announcement of the project here:
Dr Katalin Tóth and her team recently published a paper in Nature Communications in which they explain, in part, how seemingly identical synaptic vesicles can be used to transmit different messages from one neuron to the next.
