Protein ‘traffic jam' in neurons linked to neurodegeneration

A new study by EPFL researchers reveals how a malfunctioning protein complex can lead to the buildup of toxic forms of Tau, a protein involved in Alzheimer’s disease and other neurodegenerative disorders.

Network assembly through cell division

ETH Zurich researchers have developed a model that explains how nerve cells in the brain connect during development. Their model reveals that the crucial factor is progressive cell division. This process leads naturally to the formation of molecular addresses that lets neurons navigate.

Strong adhesion thanks to cavitation bubbles

Canadian researchers have discovered that they can stick hydrogel plasters to the skin very effectively using ultrasound. ETH Zurich professor Outi Supponen has now explained the underlying mechanism: imploding bubbles that form within the adhesive located between the plaster and the skin anchor the one on the other.

Sealing leaks in the stomach or intestine

ETH Pioneer Fellow Alexandre Anthis has developed a patch that seals surgical sutures on the intestines or the stomach. The material designed can also detect any leakage at an early stage – thus preventing serious complications.

Hydrogel keeps vaccines alive

Most vaccines require constant refrigeration during shipment to remain effective. An international research team led by ETH Zurich has now developed a special hydrogel that vastly improves the shelf life of vaccines, even without refrigeration. The development could save many lives and lower the cost of cold chains.

A textbook comes to life: Augmented reality for dental specialists

Game developers from the ETH Game Technology Center have created an app that explains bone remodelling in a playful way. If students point the camera of their mobile device at the textbook, they find themselves transported to the bone’s surface, where they help cells break down bone tissue.
