Next-gen organoids grow and function like real tissues

Bioengineers at EPFL have created miniature intestines in a dish that match up anatomically and functionally to the real thing better than any other lab-grown tissue models. The biological complexity and longevity of the new organoid technology is an important step towards enabling drug testing, personalized medicine, and perhaps, one day, transplantations.

Atomistic modelling probes the behavior of matter at the center of Jupiter

EPFL professor and NCCR MARVEL project leader Michele Ceriotti and colleagues have developed a physics-based machine learning approach to examine the behavior of hydrogen at extremely high pressures. The model reveals evidence of continuous metallization, and so has significant implications for planetary science. More fundamentally, it shows the way ahead for a simulation-driven change in how we understand the behavior of matter in fields as diverse as drug development and alloys for automobiles...

Discovery shows promise for treating Huntington's Disease

Scientists at the lab of Professor Hilal Lashuel at EPFL have identified a new enzyme called "TBK1" who plays a central role in regulating the degradation and clearance of the huntingtin protein and introduces chemical modifications that block its aggregation. "We believe that this represents a viable target for the development of possible treatment of Huntington's disease," says Lashuel.

This clear face mask solves one of the biggest issues about masks by making it easier to smile and talk to people

Swiss researchers have developed a clear face mask designed to make the interaction between healthcare workers and their patients more personal. The mask may enter the market as early as 2021 and will be sold to the medical community first, with the possibility of eventually being available to the general public. As the coronavirus disease has resulted in millions adapting to covering their faces in public, communicating with others has also become more difficult, especially for those in the d...

The smallest motor in the world

A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor is that it moves exactly at the boundary between classical motion and quantum tunneling -- and has revealed puzzling phenomena to researchers in the quantum realm.

Transparent face mask startup inhales $1M seed round

A Swiss startup called HMCARE, spun out of the École polytechnique fédérale de Lausanne, has raised a million Swiss Francs (equivalent to about $105 million) to commercialize its transparent and relatively eco-friendly surgical masks. The founders were inspired by healthcare workers in the 2015 Ebola outbreak and at children’s hospitals around the world working closely with patients but unable to show their faces. Likewise parents and relatives of immunocompromised people who must make a human...
