Advancements in attosecond soft-X-ray spectroscopy by ICFO researchers have transformed material analysis, particularly in studying light-matter interactions and many-body dynamics, with promising implications for future technological applications.

X-ray absorption spectroscopy is an element-selective and electronic-state sensitive technique that is one of the most widely used analytical techniques to study the composition of materials or substances. Until recently, the method required arduous wavelength scanning and did not provide ultrafast temporal resolution to study electronic dynamics.

Over the last decade, the Attoscience and Ultrafast Optics group at ICFO le, d by ICREA Prof. at ICFO Jens Biegert h, has developed attosecond soft-X-ray absorption spectroscopy into a new analytical tool without the need for scanning and with attosecond temporal resolution.[1,2].

Neurons in the brain communicate with each other at their synapses. It has long been understood that this communication occurs through biochemical processes. Here, we reveal that mechanical tension in neurons is essential for communication. Using in vitro rat hippocampal neurons, we find that 1) neurons become tout/tensed after forming synapses resulting in a contractile neural network, and 2) without this contractility, neurons fail to fire. To measure time evolution of network contractility in 3D (not 2D) extracellular matrix, we developed an ultrasensitive force sensor with 1 nN resolution. We employed Multi-Electrode Array and iGluSnFR, a glutamate sensor, to quantify neuronal firing at the network and at the single synapse scale, respectively. When neuron contractility is relaxed, both techniques show significantly reduced firing. Firing resumes when contractility is restored.

This year gave rise to an incredible mix of brain implants that can record, decode, and alter brain activity.

It sounds like déjà vu—brain-machine interfaces also lived rent free in my head in last year’s roundup, but for good reason. Neuroscientists are building increasingly sophisticated and flexible electronic chips that seamlessly integrate machine intelligence with our brains and spinal cords at record-breaking speed. What was previously science fiction—for example, helping paralyzed people regain their ability to walk, swim, and kayak—is now reality.

This year, brain implants further transformed people’s lives. The not-so-secret sauce? AI.

Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves dissolve into a quark liquid.

In a new study, published in the journal Physical Review B, researchers addressed the question of whether the liquids of nucleons and quarks are fundamentally different.

Their suggest that these liquids are different. Both types of liquids produce vortices when they rotate, but in liquids, the vortices carry a “color-magnetic field,” similar to an ordinary magnetic field. There is no such effect in nucleon liquids. Thus, these sharply distinguish quark liquids from nuclear liquids.

Alter 3 has just been unveiled by the University of Tokyo and its powered by GPT-4, capable of human-like activities and interpreting verbal instructions. Researchers at the Technical University of Munich developed a self-aware robot with proprioception, enhancing its movement and interaction capabilities. The University of Southern California introduced RoboCLIP, an algorithm that trains robots to perform tasks in new environments with minimal instruction. Intel Labs and partners created advanced motor control for robots using hierarchical generative models, significantly improving their ability to perform complex tasks.\
