Bacteria in the human gut go to war in order to protect themselves against attacks of the “spear-wielding” cholera bacterium Vibrio cholerae or other pathogens, an EPFL study has found.

Scientists at EPFL and Dartmouth College in the US have developed a system that can, for the first time, both pinpoint the exact location of a tumor and measure its depth. Their technology employs a high-tech camera developed at EPFL’s Advanced Quantum Architecture Laboratory.

Reactive electrophilic drugs like Tecfidera, approved for the treatment of relapsing multiple sclerosis, show a lot of potential but are also mystery. Their effects are notoriously difficult to study, which hampers progress testing and approving them. EPFL scientists have now used an innovative chemical method to uncover the biological mechanisms of Tecfidera, providing a powerful tool for exploring other reactive electrophilic drugs.

Under an initiative by EPFL’s Center for Imaging, a team of engineers from EPFL and Universidad Carlos III de Madrid have developed a plugin that makes it easier to incorporate artificial intelligence into image analysis for life-science research. The plugin, called deepImageJ, is described in a paper appearing today in Nature Methods.

A revolutionary implant developed at EPFL allows neuroscientists to activate or inhibit specific spinal-cord neurons by applying light at a specific wavelength. It will give researchers insight into how the nervous system works and the chance to develop new ways of treating neurological disorders.
