The brain: seeing between the fibers of white matter

The principle behind diffusion imaging and tractography is exploring how water spreads through our brain in order to study the structure of neurons. Doctors can use this method to improve their understanding of brain disease. Pietro Gori, a researcher in image processing at Télécom ParisTech, has just launched a project called Neural Meta Tracts, funded […]

What are fine particles?

During peak pollution events, everyone is talking about them. Fine particles are often accused of being toxic. Unfortunately, they do not only come out during episodes of high pollution. Véronique Riffault, a researcher in atmospheric sciences at IMT Lille Douai, revisits the basics of fine particles to better understand what they are all about.   […]

Understanding methane hydrate formation to revolutionize pipelines

Since hydrocarbon is always drawn from deep in the sea floor, oil companies face potential obstruction problems in their pipelines due to the formation of solid compounds: methane hydrates. Ana Cameirao, an engineer and PhD specializing in industrial crystallization at Mines Saint-Étienne, is hoping to understand and model this phenomenon. She has contributed to the creation […]

New Caledonia: a mine challenging democracy

When an industrial mining complex wanted to release a pollutant into their lagoon in the late 1990s, the inhabitants of the southern province of Grande Terre took action. In their fight against the environmental and cultural danger, the citizens found it difficult to make their voices heard. Today, almost 20 years have passed since the […]

Dam-break phenomenon in optical fibers

Last May, for the first time, researchers from the University of Lille and IMT Lille-Douai exposed a photon dam breaking in an optical fiber. These results provided the experimental confirmation for an old theory that dates back over 50 years. Above all, this research reveals a surprising analogy with a water dam break, creating the […]
