Before his misadventures in government efficiency, Musk promised to revolutionize commuting with a subway that would speed passengers between DC and Baltimore in a matter of minutes. The project was a farce—and a sign of things to come.

Quantum internet is approaching faster than many expected. At the same time, the world still runs on classical encryption that quantum computers are projected to break within the next decade.Enterprises, governments, and consumer networks rely on cryptographic foundations that will not withstand a quantum computer with cryptographic relevance. Post-quantum standards were finalized in 2024, and regulators have begun setting migration timelines. The transition is an infrastructure upgrade that must start now.Telcos sit at the center of this shift.They move the world’s data and operate the physical networks where quantum security will be deployed. According to STL Partners, 35 operators are already active across 75 quantum-related projects, from pilots to commercial launches.Telco Momentum is building, and yet the risk is familiar: Telcos can either shape the quantum internet and own the trust layer, or remain passive transport providers while others capture the value. As quantum capabilities move closer to the network, the strategic choice cannot be deferred.

In the semiconductor industry, Arm is everywhere and nowhere. Designs from the British-based, American-listed, Japanese-controlled firm sit in almost all the world’s smartphones and most other connected devices. Yet Arm does not sell a single chip. Customers license its designs, tweak them if they wish and produce the chips themselves (or have them made). Arm pockets an upfront licence fee and a slim per-chip royalty. The model has made it ubiquitous. More than 300bn chips built on its designs have been shipped—over 30bn of them last year alone.

China has long been a counterfeiting hub. Shoppers do not have to look far to find fake Nestlé food seasoning or imitation Nike sneakers. And brands are not the only form of intellectual property (ip) that is readily pilfered. Foreign multinationals that set up shop in the years after China opened its economy to the world often complained of their trade secrets being stolen. General Motors, an American carmaker, discovered in 2003 that a Chinese partner was rolling out a model strikingly similar to one of its own. Kawasaki, a Japanese industrial giant, and Siemens, a German one, believe their technology was nabbed to help build China’s extensive high-speed rail network.

#dotdot - Frictionless Wireless Connectivity for Incremental Revenue Generation. Extend network reach, enable opportunistic connectivity, and unlock new revenue streams — without deploying new infrastructure.

L’idée d’un téléphone Starlink, directement relié à la constellation de satellites de SpaceX, agite depuis plusieurs mois la techosphère mondiale. Si des fuites persistantes et des discussions internes chez le groupe laissent entrevoir un appareil grand public capable de se connecter sans passer par les réseaux mobiles traditionnels, le projet oscille toujours entre rumeurs, déclarations ambiguës d’Elon Musk et analyses stratégiques pointues.

Un créateur a conçu un parapluie autonome capable de voler au-dessus de son utilisateur, combinant un quadricoptère dissimulé et un objet du quotidien pour supprimer totalement le geste de le tenir. Grâce à une caméra à profondeur et un Raspberry Pi, le parapluie détecte la position de la personne et s’ajuste en temps réel pour rester centré, sans pilotage manuel. Plus proche d’une démonstration que d’un produit commercial, le projet questionne notre rapport aux objets ordinaires et imagine un futur où ils nous accompagnent plutôt que d’être portés.

A humanoid robot that walks, maintains eye contact, and displays subtle facial expressions has drawn attention on Chinese social media after videos showcasing its capabilities were circulated. The robot, named Moya, was unveiled in Shanghai by the robotics company DroidUp, which describes it as the world’s first fully biomimetic embodied intelligent robot.

The AI value chain economics at this stage is focused on infrastructure. AI value creation is concentrated upstream, where capital intensity is highest and scale advantages compound most rapidly. The market rewards balance sheets, not clever prompts. Training and inference workloads demand dense compute, high-bandwidth memory, optical interconnects, and ample power. Those inputs scale poorly for small players and extremely well for incumbents.Gartner frames 2026 as the Trough of Disillusionment. Enterprises prioritize predictable ROI over experimentation. AI gets sold by incumbent vendors and bundled into existing contracts rather than procured as standalone moonshots. That behavior reinforces concentration. Buyers choose suppliers already embedded in their infrastructure stack.

Des jeunes pousses aux scale-up plus matures, un nombre croissant de start-up se détournent des investisseurs, par choix stratégique ou parce que les conditions ne s'y prêtent plus.

Developing mechanically tough and sustainable plastics from renewable resources such as biomass may certainly give a promising solution to the replacement of petroleum-based plastics and eliminate microplastics. Here, we report a cellulose-based supramolecular plastic (CMCSP) synthesized by supramolecular “ionic” polymerization of carboxymethyl cellulose (CMC) as an oxyanionic monomer and a hyperbranched polyguanidinium ion (PEIGu) as a cationic monomer. CMCSP is mechanically strong but inherently brittle. However, as highlighted in the present paper, we could overcome the brittleness issue by adding (2-hydroxyethyl)trimethylammonium chloride (choline chloride, ChCl) to CMCSP. This FDA-approved, biodegradable ionic human nutrient served as a particular plasticizer, enabling broad modulation of stiff, glassy CMCSP to a tough, flexible material and further to a soft, elastic material. We demonstrated that plasticized CMCSPChCl could be processed into a flexible plastic bag, which was mechanically tough but perfectly dissociable in seawater and closed-loop recyclable with electrolytes. Hence, CMCSPChCl never generates microplastics.

96 $, c’est ce que coûte aujourd’hui la minute de calcul quantique chez un grand cloud provider. Le quantique n’est plus un fantasme de laboratoire : les machines sont disponibles, les tarifs clairs, les capacités démontrées. En d’autres termes, il suffit à un acteur malveillant, étatique ou criminel, d’estimer ce qu’il lui en coûterait de déchiffrer des données en sa possession et le bénéfice qu’il pourrait en tirer.

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.

With the development of organic bioelectronics, there has been interest in making stretchable semiconductors with acceptable performance. Most approaches to date rely on blending a semiconductor with an elastomer and perform well electronically, but they have a modulus much higher than biological tissue and cannot be modulated through the insertion of ions. Liu et al. created a secondary hydrogel network that facilitated the formation of a continuous phase of a primary redox-active polymer. This composition makes it possible to produce millimeter-thick semiconducting layers with biological compatibility. By controlling the hydrogel’s porosity, the researchers optimized ionic and electronic mobility and demonstrated electrochemical transistors with a high on/off switching ratio.

Unleashing prodrugs through nitro-reduction is a promising strategy in cancer treatment. In this study, we present a unique bioorthogonal reaction for aromatic nitro reduction, mediated by 4,4‘-bipyridine. The reaction is a rare example of organocatalyst-mediated bioorthogonal reaction. This bioorthogonal reaction demonstrates broad substrate scope and proceeds at low micromolar concentrations under biocompatible conditions. Our mechanistic study reveals that water is essential for the reaction to proceed at biorelevant substrate concentrations. We illustrate the utility of our reaction for controlled prodrug activation in mammalian cells, bacteria, and mouse models. Furthermore, a nitro-reduction-annulation cascade is developed for the synthesis of indole derivatives in living cells.

OpenAI dévoile Prism, une nouvelle application conçue pour faciliter la recherche scientifique, à l’image de Claude Code. Cette initiative vise à offrir aux chercheurs des outils innovants pour accélérer l’analyse et la compréhension des données scientifiques.

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.

L’accord noué avec TerraPower, société cofondée par Bill Gates, retient particulièrement l’attention. Il prévoit le financement et le développement de deux réacteurs capables de fournir jusqu’à 690 mégawatts, dès 2032 si tout se déroule comme prévu. Mais ce n’est pas tout : six autres installations pourraient suivre, totalisant potentiellement 2,1 gigawatts supplémentaires d’ici trois ans. Particularité technique : ces sites reposeront sur les réacteurs « Natrium », utilisant le sodium comme fluide caloporteur en lieu et place de l’eau – un choix jugé plus prometteur par certains experts.

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.
