Recycling using supercritical fluids (ven., 15 mars 2024)
Whether trainers or batteries, some multilayered objects still resist recycling… not for very long. This report takes you to the ICMCB laboratory where these various elements are separated using supercritical fluids, in the context of Global Recycling Day on 18 March and France's Recyclablity, recycling and re-using recycled materials project headed by the CNRS.

Are white holes dawning at last? (Thu, 14 Mar 2024)
As opposed to black holes, white holes are thought to eject matter and light while never absorbing any. Detecting these as yet hypothetical objects could not only provide evidence of quantum gravity but also explain the origin of dark matter.
