Regeneration across complete spinal cord injuries reverses paralysis
Research
EPFL
A complete spinal cord injury leads to irreversible paralysis. Scientists at .NeuroRestore report in Science that they have developed a gene therapy that was proven in mice to stimulate nerve regrowth across such injuries and guide nerves to reconnect to their natural targets below the injuries in order to restore motor function.
Genetically modifying individual cells in animals
Research
ETH Zurich
Researchers at ETH Zurich have developed a method that lets them genetically modify each cell differently in animals. This allows them to study in a single experiment what used to require many animal experiments. Using the new method, the researchers have discovered genes that are relevant for a severe rare genetic disorder.
A Lab-on-a-Chip for T cell screening and sorting
Research
EPFL
Using high precision microfabrication and microfluidics, Clémentine Lipp has developed a tool with the potential to automate T cell screening and sorting—an essential task in immunology. 
Organoids revolutionize research on respiratory infections
Research
EPFL
In a breakthrough for bioengineering, researchers at EPFL have developed organoids that can model the human respiratory tract. The organoids, called AirGels, allow them to uncover the mechanism by which antibiotic-resistant pathogens like Pseudomonas aeruginosa infect the respiratory tract.
EPFL scientists unlock new horizons for cryogenic microscopy
Research
EPFL
EPFL scientists have developed a new research instrument for observing biological tissue samples prepared using a method discovered about forty years ago by Nobel Prize winner Jacques Dubochet, emeritus professor at the University of Lausanne. Their instrument – the only one of its kind in the world – opens up promising new avenues of research.
Take a deep breath
Research
ETH Zurich
Pulmonary surfactant is a special fluid released by cells in the lungs. For premature babies and COVID-19 patients in intensive care, it can mean the difference between life and death. An ETH materials scientist hopes to shed some light on this complex substance.
