Detecting problems of the anti-bleeding system in 60 minutes

Various diseases can cause hemorrhages or thromboses, sometimes fatal, resulting in particular from complications during surgery. This may take the form of a dysfunction of the platelets (hemostasis), the blood cells that plug the holes in the damaged blood vessels. Researchers from the University of Geneva (UNIGE), the University of Franche-Comté (UFC) and the Etablissement français du Sang (Bourgogne Franche Comté), have developed a device called BlooDe to study the plugging capacity of platelets.

From one brain scan, more information for medical artificial intelligence

MIT researchers have devised a novel method to glean more information from images used to train machine-learning models, including those that can analyze medical scans to help diagnose and treat brain conditions.

Advanced computational modeling of the gut for biodefense

The Nutritional Immunology and Molecular Medicine Laboratory (NIMML) has developed a high-resolution model of the gut immune system by using advanced computational systems. The new high-performance computing (HPC)-driven model of the gut predicts new emerging behaviors and responses to biological threats. The gut ecosystem includes trillions of interactions between host epithelial and immune cells, molecules (cytokines, chemokines and metabolites) and microbes is a massively and dynamically interacting network, similar to a multidimensional jigsaw puzzle with pieces that are constantly changing shape. These interactions with cooperativity and feedback lead to nonlinear dynamics and unforeseen emergent behaviors across spatiotemporal scales. The NIMML model of the gut facilitates discovering new knowledge within this complex system for biodefense applications.

PSI imaging helps with rocket launches

Rockets from the European Space Agency (ESA) fly into space with support from the Paul Scherrer Institute (PSI). Imaging carried out at PSI in cooperation with Dassault Aviation ensures the quality of certain components of the Ariane 5 and Vega launch vehicles. With the help of the neutrons generated at the neutron source SINQ, PSI researchers are screening so-called pyrotechnic components that are installed in the ESA rockets. These components, which act like fuse cords and igniters, ensure, among other things, that the booster rockets are dropped at the right hundredth of a second. The Ariane launch on 20 June took place with components that had been examined at PSI.
