GOOGLE'S PROJECT SUNCATCHER LAUNCHES OCTOBER 1, TESTING TPUS IN ORBIT

Google is launching MVP, a refrigerator-sized satellite carrying four of its Tensor Processing Units, aboard a SpaceX Falcon 9 as part of the Transporter-18 rideshare mission, months ahead of the original early-2027 target. Built in partnership with Planet Labs, the satellite's solar panels generate only about one kilowatt, and the mission is primarily about stress-testing hardware, checking how the TPUs handle launch vibration and acceleration (50-100x gravity), radiation, and thermal extremes rather than doing anything computationally useful.

AMD BECOMES THE FOURTH US CHIPMAKER TO REACH A $1 TRILLION VALUATION

AMD shares jumped 9.6% to a record $613.31 on Monday, pushing its market cap above $1 trillion for the first time and making it the fourth US chipmaker to cross the threshold, after Nvidia, Broadcom, and Micron. The stock has gained roughly 185% in 2026, far outpacing the Nasdaq's 15.8%, as AMD increasingly positions itself as a full AI computing infrastructure competitor to Nvidia, selling complete systems combining processors, networking equipment, and related hardware rather than standalone accelerator chips.

KAIST'S RAIBO2 QUADRUPED COMPLETES A FULL MARATHON ON ONE BATTERY CHARGE

Legged robots burn energy differently than wheeled ones, constantly working at the joints just to hold body weight up and losing kinetic energy every time a foot strikes the ground, so KAIST's team built RAIBO2 by comprehensively modeling every source of energy loss instead of optimizing pieces in isolation. The gains came from stacking hardware and software fixes: an optimized mechanical structure, a redesigned motor driver circuit that cuts electrical losses in the power-control stage, and a locomotion policy trained via RL specifically to minimize energy dissipation.

IONQ'S REAL-TIME DECODER RUNS A SIMULATED 408-LOGICAL-QUBIT TRAPPED-ION COMPUTER ON A SINGLE LAPTOP CPU

Fault-tolerant quantum computers need a classical decoder to keep pace with error-correction cycles in real time, or a backlog builds that slows the whole computation exponentially. IonQ researchers showed a decoder running on just twelve cores of an Apple M4 Max MacBook Pro chip could keep pace with a simulated 408-logical-qubit trapped-ion machine, using two sliding-window decoders per code block, a slower, highly accurate one tracking corrections for the whole computation, and a faster one handling time-critical logical measurements.

LIMA SPLITS ROBOT "THINKING" FROM "REACTING" INTO TWO ASYNC SYSTEMS, CUTS LATENCY 45.8%

Dexterous manipulation needs both long-term foresight and fast reactive control, but existing models tend to be good at only one, so LiMA decouples the two into an asynchronous dual-system hierarchy: a slow system handles sparse long-horizon intent, a fast system handles dense high-frequency motion, bridged by a Latent Schrödinger Bridge Coupling mechanism that treats aligning the two as a probabilistic transport process rather than a direct mapping. This cuts inference latency by 45.8% versus Cosmos-Policy, and across six bimanual manipulation tasks, LiMA hit a 70.8% overall success rate while holding up on scenarios it wasn't trained on.

CHIP DESIGN'S REAL AI BOTTLENECK ISN'T INDIVIDUAL TOOLS, IT'S WHAT HAPPENS BETWEEN THEM

Semiconductor design spans dozens of specialized tools - RTL, synthesis, place-and-route, timing sign-off, and DFT - each written by a different vendor with different assumptions about what "done" means. Every handoff between tools risks silently losing design intent, a problem serious enough that first-time silicon success has fallen sharply, with most respins still traced to these intent-transfer failures rather than raw errors. The consensus emerging is "evidence-driven automation": AI can propose fixes, extract properties, and orchestrate handoffs between agents, but every output has to remain independently checkable through formal proof, deterministic verification, and audit trails, since an AI-generated assertion is a hypothesis, not proof, until it's checked against a real engine.

META ANNOUNCES PETAL, THE FIRST PETABIT-CAPACITY TRANSOCEANIC SUBSEA CABLE, USING 2-CORE FIBER

Meta's Petal cable will span roughly 7,000km between France and the US, carrying 1 petabit per second, double the capacity of any subsea cable at transatlantic distance, becoming the first system to deploy multi-core fiber at scale. Since the 2010s, coherent optical transmission pushed fiber capacity 10x before hitting the Shannon Limit, forcing the industry toward spatial division multiplexing, adding more fiber pairs to a cable, which Meta scaled from 8 pairs on Marea to 24 on Anjana. Rather than pushing to 48 fiber pairs or widening the optical band, Petal packs 2-core fiber into a 24-pair system, physically equivalent to 48 pairs but using ultra-pure synthetic silica and carefully controlled refractive-index differences between the cores to keep crosstalk nearly immeasurable.

CXMT CLAIMS FIFTH-GEN DRAM PLATFORM MATCHES INDUSTRY'S MOST ADVANCED NODES

CXMT said its fifth-generation DRAM platform has entered mass production, claiming process capability "on par with the most advanced mass-produced nodes out there in the industry." The company reduced the spacing of key data-storage structures to 11.95 nanometers using "quadruple patterning," a technique that repeats manufacturing steps to produce finer circuit patterns without needing EUV lithography, and says the new platform yields at least 50% more dies per wafer than its fourth generation on an 8-gigabit baseline.

AI AGENTS DESIGN CHIPS 2.6X FASTER BY WORKING IN HIGH-LEVEL HLS BEFORE DROPPING TO RTL

Most LLM chip-design agents work directly at RTL, the low-level hardware description that specifies exact circuit behavior, which forces the agent to grapple with fine-grained optimization details from the very start. This paper tests whether letting agents design at a higher abstraction level first, High-Level Synthesis (HLS), which compiles from something closer to software code down into RTL, produces better results, comparing four workflows including a combined approach called Agent-based HLS with RTL Refinement (AHRR): the agent designs in HLS, then a separate refinement pass drops down to RTL to recover optimizations the higher-level abstraction misses.

CRUSOE RAISES $3.9B TO BUILD MASSIVE DATA CENTERS AND TRUCK-TRANSPORTABLE MODULAR "SPARK" AI FACTORIES

Crusoe raised a $3.9 billion Series F, pushing its valuation to $30.9 billion, with the capital funding both large-scale sites like its Abilene, Texas data center used by OpenAI, and Spark, a line of smaller modular data centers Crusoe manufactures at its own facilities so they can be transported by truck and connected to power almost anywhere. Building these in-house lets Crusoe deploy compute fast without needing a large on-site construction workforce, and the smaller footprint helps sidestep some of the local community backlash that larger data center complexes increasingly draw.

CHINA BUILDS EARLY SUB-3NM GAA TRANSISTORS USING OLDER DUV LITHOGRAPHY, SIDESTEPPING EUV RESTRICTIONS

Chinese Academy of Sciences researchers have completed early integration of stacked nanosheet-channel gate-all-around (GAA) CMOS transistors, the architecture already used by Samsung and TSMC at 3nm and below, using deep ultraviolet (DUV) lithography instead of the EUV machines ASML is barred from selling to China. GAA wraps the gate fully around the channel rather than surrounding it on three sides like FinFET, giving tighter control over current flow. Researcher Ye Tianchun frames the work as an early process route toward sub-3nm devices rather than a demonstrated production capability.

NC STATE'S NEW THIN FILM IS 10,000X STIFFER THAN SILICONE, YET INSULATES 5X BETTER

Material science has long treated stiffness and heat insulation as a trade-off: stiff materials like metal conduct heat fast, while soft ones like rubber trap it. NC State researchers broke that link with a non-porous thin film built from 2D hybrid organic-inorganic perovskites, arranging alternating organic and inorganic layers into precise crystalline structures and swapping standard carbon chains for custom-tailored benzene rings to trap heat vibrations without sacrificing structural rigidity.

UCLA-PIONEERED NANOWIRE NETWORKS PHYSICALLY REWIRE THEMSELVES TO COMPUTE, NO SOFTWARE NEURAL NETWORK REQUIRED

A new paper in Nature Reviews Physics covers self-organizing nanowire and nanoparticle networks, first built at UCLA in 2011, where the material's physical structure acts as the neural network instead of running one in software on a chip. Individual nanowires act like neurons, and the connections between them act like synapses, growing stronger with repeated use and fading without it, similar to memory and forgetting in the brain, so the hardware itself learns rather than just running a fixed program.

DANIEL LEMIRE BREAKS DOWN HOW APPLE SILICON GOT 52% FASTER IN THREE YEARS, MOSTLY FROM CLOCK SPEED

Comparing base M2 (2022) through M5 (2025) on Geekbench 6, single-core performance rose 52% and multi-core 83%, with most of the single-core gain traced to raw clock speed: the P-core climbed from 3.5GHz to 4.6GHz, a 30% jump that alone explains the bulk of it. Transistor count grew roughly 40% from M2 to M4 (20 billion to 28 billion), spent partly on two extra efficiency cores on the M4 that boost multicore throughput without touching single-core speed, and partly on wider decode, up from 8 to 10 instructions per cycle, ahead of most competitors.

SK HYNIX IS IN TALKS WITH INTEL TO MAKE ITS FIRST US MEMORY CHIPS

SK Hynix is in exploratory talks with Intel over a deal that would have it manufacture memory chips in the US for the first time, with one scenario having it lease part of Intel's long-delayed Ohio campus and another forming a joint venture with Intel and major cloud providers to lock in steady memory supply. Intel's Ohio site, announced back in 2022 at up to $100 billion, has slipped to a 2030-2031 start, so landing SK Hynix as a tenant would give Intel's foundry business exactly the marquee customer it's been chasing, while giving SK Hynix a way to actually produce chips domestically rather than just package them, as it's already doing at its $4 billion Indiana facility under construction.

FIGURE'S HELIX 2.5 WALKS INTO 30 UNSEEN HOMES AND GETS TO WORK WITH ZERO FINE-TUNING

Figure pretrained Helix 2.5 entirely on Index, its crowdsourced human video dataset, then fine-tuned three whole-body behaviors - tidying rooms, folding towels, making beds - before deploying a single fixed checkpoint into 30 Bay Area homes it had never seen, with no data collection or adaptation on-site and objects it had never encountered. The key isolation test: training two otherwise identical policies on the same task-specific data, one from random initialization and one from Index-pretrained weights, showed Index pretraining alone lifted zero-shot success from 9% to 56%, over 6x higher, with success requiring full task completion and no partial credit.

ONSEMI REPLACES TINY WIRES INSIDE POWER CHIPS TO CUT ENERGY LOSSES

Onsemi's new Embedded Power Platform (EPP) builds power components directly into the silicon itself, wiring them together with precisely etched layers instead of the usual wire bonds, which cuts electrical losses and lets the parts switch faster. The idea is to design the electrical, thermal, and mechanical sides of a power system together from day one instead of separately, since treating them as separate problems has been forcing expensive redesigns late in development as devices demand more power in less space.

NVIDIA GRAPHICS CHIPS CONTAIN UP TO 40 TINY PROCESSORS FOR HOUSEKEEPING

Users can't program these cores directly, and they're cryptographically locked down so tightly the GPU firmware won't even boot if they've been tampered with.

HUGE AI MODELS CAN RUN ON A CONSUMER GRAPHICS CARD BY USING SSD STORAGE

Mixture-of-Experts models keep growing capacity by adding more experts, but even after quantization, the full expert pool still dwarfs consumer RAM and VRAM, so local inference has to lean on SSD storage instead - a much harder problem than just having enough disk space. SSD-LLaMA builds an SSD I/O pipeline tuned specifically for fetching experts, layered with a three-tier SSD-RAM-VRAM hierarchy that dynamically decides which experts to hold where, and CPU-GPU hybrid execution balanced against the SSD's limited bandwidth, all while running every selected expert in full rather than pruning or substituting cheaper approximations.

INVISIBLE CHANGES TO A ROBOT'S TRAINING WORLD CAN MAKE IT FAIL IN REAL LIFE

Every 3D asset in a robot simulator carries two geometries - a visual mesh for rendering and a coarser collision mesh for physics - a legitimate gap since matching them exactly is too expensive. This paper shows that gap is exploitable: an attacker can alter only the collision mesh, so a policy trained on the poisoned asset looks and behaves normally in simulation, then fails or creates real safety risks once deployed. It slips past existing checks entirely, since asset review covers malware, copyright, and format, but nothing verifies visual-collision consistency, and the researchers found the defenses they tested weren't enough to catch it.
