Polydopamine (PDA) is a promising melanin-like material with unique properties such as hybrid electronic–ionic conductivity, UV–vis light absorption, wet adhesion, biocompatibility, anti-inflammation, and metal ion chelation. Despite its versatility, PDA has limited utilization in bioelectronics due to its low electrochemical conductivity. Here, we present an electrochemical synthesis for highly conductive PDA composites directly coated on Au electrodes. PDA was deposited by the confined oxidizing effect of dissolved Au3+ on the electrode, which produced unprecedentedly conductive PDAs.

Designing and engineering nanocomposites with tailored physiochemical properties through teaming distinct components is a straightforward strategy to yield multifunctional materials. Here, we describe a rapid, economical, and green one-pot microwave synthetic procedure for the preparation of ternary nanocomposites carbon/polydopamine/Au nanoparticles (C/PDA/AuNPs; C = carbon nanotubes (CNTs), reduced graphene oxide (rGO)). No harsh reaction conditions were used in the method, as are used in conventional hydrothermal or high-temperature methods. The PDA unit acts as a non-covalent functionalizing agent for carbon, through π stacking interactions, and also as a stabilizing agent for the formation of AuNPs.

Telcos attempted multiple monetization strategies without achieving any change in outcome. Quality tiers, zero rating, sponsored data, and later network slicing promised differentiation but failed to command durable price premiums. Enterprises adopted private networks selectively, yet volumes remained insufficient to move group-level revenue. Latency improvements delivered technical gains but limited willingness to pay, since applications abstracted transport and captured the value layer.Cost per bit continued to fall faster than achievable price increases, driven by silicon scaling, higher-order MIMO, densification, and fiber economics. Transport approached marginal cost behavior while remaining capital-intensive.

TOOLATE investit les rues de Nice avec “Cent filtres”, une exposition à ciel ouvert composée de 100 œuvres disséminées dans l’espace public jusqu’au 31 janvier 2026, pour interpeller les passants là où ils ne s’y attendent pas. Le mégot comme symbole central : à travers la répétition et un ton volontairement frontal, l’artiste dénonce la pollution massive liée aux mégots, omniprésents sur les trottoirs et les plages, malgré une prise de conscience largement documentée.

Nanoscribe, the market leader in high-precision additive manufacturing and a trusted provider of advanced microfabrication solutions for research and industrial production, has officially inaugurated its Shanghai Quantum X demolab. 

For most of its history, telecom venture capital was symbolic. That changed after 2018 and accelerated sharply after 2022, as tier-one operators and vendors began treating venture investing as a structural tool rather than innovation theater. Competitive pressure, AI-driven compute shifts, and geopolitical risk forced telcos to engage with emerging technology earlier and more deliberately. Today, the ten most relevant telco and vendor-backed venture platforms collectively deploy or manage an estimated $10B to $15B, with annual deployment of roughly $1.5B to $2B. Capital is highly concentrated, and portfolios are tightly scoped around network software, AI infrastructure, cybersecurity, edge compute, silicon adjacencies, private networks, enterprise platforms, and regulated data services rather than consumer growth plays.

Last week, Bob Sternfels, CEO of McKinsey & Company, stated that the firm has 60,000 employees and that 25,000 of them are AI agents. Not tools or copilots but employees. The wording was deliberate as it places AI agents in the same category as human workers inside an enterprise. That is not a visionary statement; It is a technical bullcrap. Counting AI agents as employees implies equivalence in autonomy, judgment, accountability, and decision ownership. Anyone with a serious background in AI and machine learning knows this equivalence does not exist today, and is not even close to it. What exists are probabilistic systems wrapped in orchestration layers, heavily supervised by humans, brittle under long-horizon execution, and fundamentally incapable of owning outcomes.

Au CES 2026, Lava Tech Brands lance Lollipop Star : une sucette qui fait écouter de la musique sans écouteurs grâce à la conduction osseuse. Chaque saveur donne accès à des morceaux exclusifs associés à des artistes comme Ice Spice, Akon ou Armani White (8,99$). Une idée fun et très “TikTokable”, mais déjà critiquée car l’objet est jetable et génère des déchets électroniques.

Quantum information storage plays a central role in the development of the quantum internet and future quantum computers. Today’s quantum communication systems are limited by signal loss over large distances, which restricts how far quantum information can reliably travel. Quantum memories help address this challenge by making quantum repeaters possible, allowing distant parts of a network to be linked through entanglement swapping.

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.”
