C’est un rendez-vous que les amateurs de montage, de musique et d’images-clés attendent chaque fin d’année : la rétrospective signée Cyril Käppeli alias Cee-Roo, artiste suisse devenu incontournable avec ses compilations aussi denses que viscérales. Fidèle à son style, il condense en quelques minutes une année entière, comme un concentré de mémoire collective… impossible à regarder distraitement.

Skyfora turns existing GNSS infrastructure, telecom cell towers, into a real-time, high-resolution weather-sensing network, unlocking 3D weather and tomography data at scale. More coverage, better data, constant updates. The next leap in forecasting.

The idea that telecom networks can be used for weather sensing is not new. GNSS-based atmospheric estimation, rain attenuation on microwave links, and radio refractivity effects have been studied for more than 20 years. The physics is well understood and already embedded in network planning and synchronization systems.

The telecom industry operates the most distributed, synchronized, and permanently powered infrastructure on the planet. Eight million radio sites span cities, roads, ports, factories, and borders.Telecom can expose not just connectivity but structured awareness: object motion, crowd flow, anomalies, risks, and environmental state. In real time, across every continent. The infrastructure already exists. What’s missing is the architecture and the will to build the sensing layer on top of it.

Two of the most common, often fatal, forms of cardiovascular disease are acute myocardial infarction and stroke. Both conditions involve compromised blood flow to target organs, resulting in dysfunction and subsequent death of cardiac and brain cells. Unfortunately, treatment options aiding the recovery phase have not been readily forthcoming over the years. In this narrative review, we explore the effectiveness of red and near infrared light treatment—known also as photobiomodulation (known henceforth as "light")—in improving the recovery process after either acute myocardial infarction or stroke in both preclinical and clinical studies. For preclinical studies, we consider the key findings gleaned from a large number of studies using a wide range of animal models that mimic the human conditions, showing that light treatment addresses the hallmarks of pathology associated with both these conditions; it stimulates mitochondrial activity, limits the infarct size, reduces inflammation and improves reperfusion.

Le géant taïwanais maintient son avance sur ses concurrents dans le secteur stratégique des semi-conducteurs avec une nouvelle génération de puces idéales pour les serveurs et l'intelligence artificielle embarquée.

La faillite de Kodak est souvent présentée comme l’illustration parfaite de la théorie de la disruption popularisée par Clayton Christensen. L’étude d'Albéric Tellier montre d’abord que Kodak n’a ni ignoré ni sous-estimé le numérique. Dès le début des années 2000, sous la direction de Daniel Carp, l’entreprise consacre près des deux tiers de sa R&D aux technologies numériques et élabore en 2003 un plan stratégique ambitieux prévoyant trois milliards de dollars d’investissements. C’est précisément ce plan qui se heurte à une opposition frontale des actionnaires.La chute de Kodak ne s’explique pas uniquement par une incapacité managériale face à la rupture technologique, mais par l’impossibilité de déployer une stratégie de rupture dans un cadre de gouvernance dominé par des investisseurs institutionnels orientés vers le court terme.

Treize ans après avoir déposé le bilan, Kodak voit de nouveau son avenir menacé. Retour sur un cas d’école du management de l’innovation… qui a suscité beaucoup de contre-vérités.

A new neuromorphic robotic skin enables humanoid robots to sense pain, detect injury, and trigger rapid reflex responses.

L’idée, si on résume, c’est un peu de traiter le soleil comme un interrupteur. Il fait nuit, mais seulement sur une partie de la Terre. Le soleil ne s’arrête jamais de briller donc ses rayons sont toujours là. C’est une source d’énergie quasiment inépuisable pour encore cinq milliards d’années en tout cas, ce qui laisse le temps de voir venir. Les deux jeunes fondateurs de Reflect Orbital pensent qu’il ne faut pas forcément améliorer le rendement des panneaux solaires ou concevoir des batteries pour stocker l’énergie. Il suffit "juste", selon eux, d’allonger les journées.

A controversial scheme will begin to reflect sunlight to Earth with satellites next year, so that dark places can be temporarily lit for visibility or energy production. But astronomers are sceptical about the plan’s efficacy and possible scientific consequences.US company Reflect Orbital, which aims to provide “sunlight on demand”, intends to launch its first satellite as soon as early 2026, beaming sunlight to 10 locations as part of an initial “World Tour”. The company then plans to launch thousands of satellites, equipped with mirrors spanning tens of metres, so that light can be reflected to Earth for “remote operations, defense, civil infrastructure, and energy generation.”

US deep-tech AI startup Tiiny AI has released a groundbreaking demonstration showing a 14-year-old PC running a 120-billion-parameter AI model smoothly without any internet connection.

From pipes to machine governance: how 5G and 6G turn the telco stack into deterministic coordination, trusted identity, and real time control for billions of robots

Revolut has not entered mobile communications to outperform network operators on coverage or spectrum efficiency. The company has entered the market because mobile connectivity has become another digital capability that fits naturally within a platform already handling identity, payments, subscriptions, rewards, travel, and daily financial behavior. When connectivity is viewed as software rather than infrastructure by the customer, the economics shift upstream.

Each company faces its own mix of tariff pressures, supply chain issues, and shifting markets, but together they tell a larger story about the challenges of building physical products in an era of global trade tensions and cheap overseas competition. From the Roomba maker that almost got acquired by Amazon to the e-bike company that couldn’t escape its Chinese supply chain, this week’s bankruptcies are a warning sign for hardware startups everywhere. 

Les robots Unitree se font pirater en 60 secondes via Bluetooth : une faille si débile qu'elle devient comique (injection de code dans les champs SSID/mot de passe) 14 000 euros de robot transformé en botnet ambulant : comment une clé AES codée en dur rend TOUS les modèles Unitree de la planète hackables d'un seul coup

At the Fangchenggang project, Walker S2 units will help border staff guide passenger queues, direct vehicles, and answer simple questions from travelers. Some robots will patrol corridors and waiting areas, watching for blocked exits or crowd patterns that might require human officers to intervene. Others will move between cargo lanes to support logistics teams, checking container IDs, confirming seals, and relaying status updates to dispatch centers. Away from the border itself, the fleet is expected to inspect steel, copper, and aluminum facilities, walking structured routes through hot industrial yards.

The robot in question ran off an internal AI agent. By exploiting a flaw in the software, the researchers were able to take over the robot while it was connected to a network, at which point the researchers had the robot use local wireless communication to spread the hack to another nearby robot that actually wasn't even connected to the network at the time. Spreading the hack from one robot to another only took a matter of minutes. Even worse, the researchers were able to issue a command for the robot to physically strike a mannequin on stage.

Impossible enfin d’évoquer cette édition sans souligner la montée en puissance des robots connectés. Le célèbre Ballie – robot sphérique jaune signé Samsung – fait parler de lui malgré ses multiples annonces reportées. Qu’il soit à nouveau sous les projecteurs ou non, la robotique domestique sera omniprésente entre aspirateurs autonomes perfectionnés et robots dotés d’algorithmes IA capables de mieux appréhender leur environnement. Les avancées autour des modèles « monde réel », censés offrir une compréhension plus fine des espaces physiques par l’IA, pourraient bien façonner les discussions cette année.

The growing demand for advanced materials, miniaturized devices and integrated microsystems calls for the reliable fabrication of complex, multiscale, three-dimensional (3D) architectures, a need increasingly addressed through light-based and laser-based processes. However, owing to the field-of-view (FOV) limitations of conventional imaging optics, existing 3D laser nanofabrication techniques face fundamental challenges in throughput, proximity error and stitching defects on the path to scaling. Here we present a scalable 3D nanofabrication platform that uses a metalens-generated focal spot array to parallelize two-photon lithography (TPL)1 beyond centimetre-scale write field areas.
