Όπως είναι ήδη γνωστό οι νευρώνες αναλύουν μια εισερχόμενη ηλεκτρική διέγερση σε υπομονάδες (ηλεκτρικούς παλμούς). Ερευνητές που εργάζονται στο πρόγραμμα Blue Brain ⎆ αποκαλύπτουν σήμερα ότι οι δενδρίτες, οι δενδροειδείς υποδοχείς του νευρώνα, συνεργάζονται στη λειτουργία της μάθησης —δυναμικά και αναλόγως του φόρτου εργασίας. Τα ευρήματα διευρύνουν την κατανόησή μας για τον τρόπο που σκεπτόμαστε και ενδέχεται να εμπνεύσουν την κατασκευή νέων αλγορίθμων για την τεχνητή νοημοσύνη.

Ρομπότ κάνουν άλματα, επικοινωνούν και συνεργάζονται σαν μυρμήγκια
Μικροσκοπικά ρομπότ εμπνευσμένα από μυρμήγκια, επικοινωνούν το ένα με το άλλο, αναλαμβάνουν ρόλους μεταξύ τους και συνεργάζονται για να διεκπεραιώσουν πολύπλοκες εργασίες.
The quantum waltz of electrons hints at the next generation of chips
EPFL researchers have successfully measured some of the quantum properties of electrons in two-dimensional semiconductors. This work in the field of spintronics could one day lead to chips that are not only smaller but that also generate less heat. _ EPFL
Reading our brain chemistry
Researchers at EPFL have developed a new device and analysis method that let doctors measure the neurochemicals in a patient’s brain. The Microsystems Laboratory 4 (LMIS4)’s system involves collecting microdroplets of cerebral fluid and analyzing them to obtain chemical data that can help doctors diagnose and treat neurodegenerative diseases._EPFL
New evidence for dark matter makes it even more exotic
Looking at massive galaxy clusters, EPFL astronomers have observed that their brightest galaxies within them “wobble” — an unexpected phenomenon in current models. The discovery, published in MNRAS, adds to the body of evidence of dark matter beyond the Standard Cosmological Model (ΛCDM). _EPFL
Self-healing materials inspired by plants
Scientists at EPFL’s Laboratory for Processing of Advanced Composites (LPAC) and the University of Freiburg’s Botanical Garden have studied how the flax plant heals itself after it has been wounded. As part of a cross-disciplinary EU research project, they measured changes in the plant’s mechanical properties, like stiffness and damping, and examined the plant’s self-repair mechanisms. Because natural fibers are being increasingly used to make composite materials, understanding how such mechanisms work can help scientists develop self-healing materials with better performance, drawing on methods inspired by nature. The research was recently published in PLOS ONE. _EPFL
A brain-system that builds confidence in what we see, hear and touch
A series of experiments at EPFL provide conclusive evidence that the brain uses a single mechanism (supramodality) to estimate confidence in different senses such as audition, touch, or vision. The study is published in the Journal of Neuroscience.
Your own virtual heart for non-invasive heart diagnostics
EPFL mathematician Alfio Quarteroni and his team are building a virtual heart model based on personalized medical images that may one day help cardiologists and cardiac surgeons non-invasively diagnose pathological heart conditions. The team recently modeled and simulated the behavior of a patient’s aortic valve._EPFL
