1 France has just inaugurated the first social housing made using 3D printing. It is a 95 m² house named Yhnova which was designed thanks to an exclusive process developed by the University of Nantes.
A robot with a laser-guided four-meter long arm lays out successive layers of material following a computer plan.
This 3D printing technique has many advantages: speed, freedom of form, little waste on the job site, less stressful handling that reduces labor strain.
2 Rather rare, brain tumors can leave sequels. To help doctors in the diagnosis of these tumors, researchers developed a machine-learning approach.
In order to initiate more effective treatments and better assess the vital prognosis, the challenge is to identify precisely the type of brain tumor that we are dealing with.
Wishing to standardize the diagnostic process, the researchers have trained a computer to analyze and classify brain tumors in different categories according to their methylation profiles, thanks to machine learning and artificial intelligence. Their system improves the accuracy of a classic histological or molecular diagnosis. In fact, 12% of the tumors of the 1,104 cases studied were changed in category, following the recommendations of the computer.
3 For the first time, scientists have measured the movement of the Etna through a hundred GPS stations placed at its edges.
According to measurements made by a hundred GPS for eleven years, Etna slides slowly towards the sea at a speed of 14 millimeters per year. This movement, although slow, deserves to be watched and taken seriously because of the risk of collapse.
The observed slip is slow but seems impossible to stop. Neither should this movement be accelerated by a fault. However, volcanoes that tend to slide in this way may collapse on the side of the downward slope.
Try Peerus, a smart and exhaustive way to be up-do-date with the latest scientific advances.
