IC and STI had the pleasure of hosting the Honorary Lecture of Professor Giovanni De Micheli, bringing together his former students who travelled from afar, as well as researchers and faculty members, to celebrate his pioneering research and academic excellence. 📚
Through his lecture, Carrying the Torch, Prof. De Micheli shared reflections on scientific collaboration, the evolution of technology, and the importance of passing knowledge on to future generations.
Thank you Nanni, for everything you have given us throughout your career to our students, to the scientific community, and to EPFL. ⚡️

#AI is a very useful tool to generate novel #protein structures, but most systems focus on producing static ‘snapshots’ of proteins. Subtle rearrangements of atoms in structures called side chains, which influence a protein’s interactions with other molecules, are not captured.
Now, scientists in EPFL’s School of Life Sciences have teamed up with data processing experts in the School of Engineering to solve this problem. They have developed an AI-based generative framework called Latent Diffusion for Full Protein Generation (LD-FPG), which produces complete, all-atom structural ensembles of proteins and their movements.
“Proteins are like tiny machines that dance and switch on and off to work but generating this ‘movie’ in full detail has been an unsolved challenge. Our LD-FPG framework is the first to do this,” the researchers say.

Researchers in the @epflcampus Flexible Structures Laboratory, @universiteitleiden and @_amolf have found a way to program #metamaterials globally with a surprisingly simple solution: #rotation!
By tuning a spinning platform’s speed, direction, and acceleration, the researchers can harness forces arising in a rotating system – such as #centrifugal and #Euler forces – to make elastic beams snap back and forth, creating a simple new way to ‘write’ multiple mechanical bits at once.

🤖 Helping robots adapt tasks to curved objects
💡Robotics researchers from the Idiap Research Institute have introduced a geometric representation for object-centric tasks like cutting, peeling, or inspecting.
⛔ These seemingly simple tasks are challenging for #robots, because they involve curved objects for which there is no global reference frame. This means that directions like ‘toward’ or ‘along’ change depending on the object’s shape and robot’s position.
↔️ ↕️ To overcome this problem, the researchers developed a method for computing local, object‑centric reference frames that define meaningful directions at any point near an object. In these local frames, object-centric tasks become simple, shape-invariant signals. Local actions are combined with the local frames to adapt tasks to a specific object shape.
In addition to enabling task-transfer across the immense shape variation of everyday items, the team’s representation can also be used to learn simple signals to generate complex behaviors over extended interactions with real objects!

⚛️ Most #particlephysics experiments require 3D tracking of elementary particles like neutrinos, which is often achieved using materials called scintillators. These are divided into many small segments, each of which emits visible light when charged particles pass through them. But this segmentation-based approach doesn't scale well as experiments grow larger.
💡Now, an ETHZ-EPFL study invites the research community to change radically the way that elementary particles are detected.
📸Moving away from segmentation, they propose using one large, solid block of scintillator material, and reconstructing particle pathways using advanced optics and timing #electronics.

Researchers in the Learning Algorithms and Systems Laboratory have developed a new robotic control framework called Kinematic Intelligence.
The method takes a human-demonstrated task, mathematically converts it into a general movement strategy, and then adapts it so that different robots can perform it based on their physical design!

Researchers from the Photovoltaics and Thin-Film Electronics Laboratory and @csemtech have developed a new #solarcell that combines exceptional voltage, high efficiency, and scalable manufacturing.
The #triplejunction device is composed of a silicon bottom cell, onto which middle and top cells made of semiconductors called #perovskites are deposited as thin films.
The new device, according to the paper published in Nature, achieves an independently certified efficiency of 30.02% -- approaching the performance of the most advanced space-grade #photovoltaics.

🦴 After only four days of mineralization, this porous, bone-like composite developed at EPFL can bear the average weight of an adult human on an area as small as 1.5 cm x 1.5 cm!
“We hope that our technology’s combination of mechanical performance, bioactivity, and energy-efficient processing will open new avenues for bone tissue engineering," says @smal_epfl head @esther.amstad .
