A study conducted by CNRS¹ researchers describes a new method of recycling silicone waste (caulk, sealants, gels, adhesives, cosmetics, etc.). It has the potential to significantly reduce the sector’s environmental impacts. This is the first universal recycling process that brings any type of used silicone material back to an earlier state in its life cycle where each molecule has only one silicon atom. And there is no need for the raw materials currently used to design new silicones. Moreover, since it is chemical and not mechanical recycling, the reuse of the material can be carried out infinitely. The associated study is to be published in Science on 24 April 2025.

Fewer than one in 10 senior authors in a prestigious physics journal are women, according to a new study.

Of 15 countries, Canada has the worst record. The 33 Canadian-led papers in Nature Physics in the last 10 years had zero senior authors who were women, according to a new study published by the journal. Author Dr. Alannah Hallas, associate professor in the UBC Stewart Blusson Quantum Matter Institute and the department of physics and astrophysics, discusses the results and how they highlight the need for further support for young scientists in the field.
