Medicine for Materials

Did you know that materials have health problems too? To diagnose their structural integrity, researchers are increasingly using techniques similar to those used in the medical field for humans. X-rays, temperature checks and ultrasound imaging are just a few of the tools that help detection of abnormalities in parts. The advantage of these various techniques […]

Xenon instruments for long-term experiments

From the ancient gnomon that measured the sun’s height, to the Compton gamma ray observatory, the microscope, and large-scale accelerators, scientific instruments are researchers’ allies, enabling them to make observations at the smallest and largest scales. Used for both basic and applied research, they help test hypotheses and push back the boundaries of human knowledge. […]

Eikosim improves the dialogue between prototyping and simulation

Simulate. Prototype. Measure. Repeat. Developing an industrial part inevitably involves these steps. First comes the digital model. Then, its characteristics are assessed through simulation, after which, the first version of the part is built. The part must then be subject to mechanical stress to assess its resistance and be closely observed from every angle. The […]

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 […]

Climate change as seen from space

René Garello, IMT Atlantique – Institut Mines-Télécom [divider style=”normal” top=”20″ bottom=”20″] [dropcap]T[/dropcap]he French National Centre for Space Research has recently presented two projects based on greenhouse gas emission monitoring (CO2 and methane) using satellite sensors. The satellites, which are to be launched after 2020, will supplement measures carried out in situ. On a global scale, this […]

Ethics, an overlooked aspect of algorithms?

We now encounter algorithms at every moment of the day. But this exposure can be dangerous. It has been proven to influence our political opinions, moods and choices. Far from being neutral, algorithms carry their developers’ value judgments, which are imposed on us without our noticing most of the time. It is now necessary to […]

VIGISAT: monitoring and protection of the environment by satellite

Following on from our series on the platforms provided by the Télécom & Société numérique Carnot institute, we will now look at VIGISAT, based near Brest. This collaborative hub is also a project focusing on the satellite monitoring of oceans and continents in high resolution.   On 12th July, scientists in Wales observed a drifting iceberg […]

Will we soon be able to control machines with simple gestures?

The “Silense” European project launched in May 2017 is aimed at redefining the way we interact with machines. By using ultrasound technology similar to sonar, the researchers and industrialists participating in this collaboration have chosen to focus on 3D motion sensing technology. This technology could allow us to control our smartphone or house with simple […]

How biomechanics can impact medicine – Interview with Jay Humphrey

[dropcap]I[/dropcap]t is a love for mechanics and mathematics, as well as an intense interest in biology and health, that led Jay Humphrey towards the field of biomechanics. Right after his PhD from the Georgia Institute of Technology in Engineering Science and Mechanics, in 1985, he pursued post-doctoral training in cardiovascular research at The Johns Hopkins […]
