Hello, this is Achintya and today we travel into the future and deep underground below Geneva, to look at plans being made at CERN for a new accelerator that would encircle the city.

We then take a stop at EPFL where students have made a 3D printer capable of printing ulta-thin structures measuring a fraction of a human hair.

And we finally arrive at the Grimsel pass between Valais and Bern where an international group of students is spending eight days isolated underground in a model of a lunar station.

⚛️💥 Plans move ahead for even larger particle collider to encircle Geneva. Scientists at CERN, the European Organization for Nuclear Research, are working on plans to build a 100 km collider, dubbed the Future Circular Collider (FCC), to delve further into the workings of the universe. If built, the deep-underground tunnel housing the FCC would be nearly twice as long as the 57-km-long Gotthard Base Tunnel in the Swiss Alps.

🧑‍🚀 Bringing the moon to the Earth. Six students from Switzerland, France, the UK and Chile will spend eight days in complete isolation from the rest of the world, in an underground “lunar station” under the Grimsel pass, created by EPFL’s Space@yourservice association. Their mission is to carry out tests, both scientific and social, and will be supported by colleagues “on Earth” who will be in 24-hour contact with the team.

🖨️ EPFL’s home-made 3D printer. When researchers at EPFL found commercial 3D printers outside their budget, they turned to their students and engineers to build one from scratch. The new device, which not only saved money but was also tailored to their requirements, can print fine structures using ultra-thin filaments within minutes. To put the size of a micron into context, an average human hair is approximately 70 microns while a human red blood cell is about five microns.


Next on the agenda

📌 14 July | Switzerland’s commitments to Agenda 2030. The launch of the University of Geneva’s French summer classes are both a chance to learn the local language and about Switzerland’s contribution to the 2030 Agenda for Sustainable Development, through the voice of the delegate to the Federal Council on the matter.


📌 16 July | AI-accelerated climate modeling. Join Professor Tapio Schneider from the California Institute of Technology in examining a new climate model that makes use of advances in machine learning and data assimilation to provide more accurate predictions.
