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 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'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.

The shader cores that do actual graphics work aren't where the RISC-V lives - it's in a collective of small management processors handling clocking, memory, security, and other housekeeping, with Nvidia VP Frans Sijstermans confirming each GPU packs 10 to 40 of them depending on the model. 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.

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.
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.
