Analyzing food quality with an artificial intestine
Analyzing food quality with an artificial intestine
Researchers have developed a miniature on-chip gastrointestinal tract in order to observe the effects of various nutrients on health. The “NutriChip” project's in vitro tests have already begun, on dairy products. What happens in our bodies when we have eaten something? Are “healthy” food products actually good for us, once they have been digested and absorbed? Supported by Nano-Tera and Nestlé, the NutriChip project developed by Martin Gijs's team at the Laboratory of Microsystems at EPFL provides new insights to these questions.

Understanding the propagation of Alzheimer's Disease
Understanding the propagation of Alzheimer’s Disease
The connections between neurons might play a role in neurodegenerative diseases, including Alzheimer's Disease (AD). In a pioneering approach to studying how neurodegenerative diseases like AD spread within the brain, researchers have developed a novel in vitro experimental method that allows them to connect healthy neurons with “infected” neurons and then observe the results.

New point of attack for breast cancer
New point of attack for breast cancer
Scientists describe how the protein phosphatase SHP2 promotes breast cancer with poor prognosis. SHP2 is necessary for the maintenance of the few tumor initiating cells (TICs) in a breast tumor.

Science of the stick-slip
Science of the stick-slip
Scientists have succeeded in modelling what happens when two bodies slide against each other and thereby release the pressure; a discovery that has implications for the understanding of the magnitude of earthquakes. David Kammer from EPFL has developed a digital model that explains what happens at the interface between two materials when they slide against each other; like a book on a table, rubber soles on linoleum, or - more to the point - tectonic plates.

Cleaning up Earth’s orbit
Cleaning up Earth’s orbit
The proliferation of debris orbiting the Earth - primarily jettisoned rocket and satellite components - is an increasingly pressing problem for spacecraft, and it can generate huge costs.

How to turn leaves into solar panels
How to turn leaves into solar panels
Photovoltaic panels made from plant material could become a cheap, easy alternative to traditional solar cells. An entirely novel approach to photovoltaics has been developed. By taking the very protein in plants that allows for photosythesis and engineering it to produce electrical current, researcher Andreas Mershin has opened the door for potentially cheap and easy to reproduce solar energy.

Swimming goes high tech
Swimming goes high tech
Scientists have developed inertial systems, worn in a full-body swimming suit, which can analyse the strengths and weaknesses of elite-level swimmers during workout sessions. It's a revolutionary new tool for coaches. Will scientists play a role in creating the next Michael Phelps or Laure Manaudou? Researchers from EPFL and University of Lausanne have at least taken the first step, by developing a tool that can help improve elite swimmers' workouts.

Protective covering for implants
Protective covering for implants
A new technology could prevent most breast implant rejections. So far, more than a quarter of all breast implants must be removed within four years, because neighboring tissues develop a rigid envelope of fibrous tissue to protect themselves from the foreign body. A company has developed a protective covering made up of a nanostructured surface and a layer of collagen that will prevent the body from rejecting the implant.
