The future leaves
signals in time.

Ten US states have passed laws permitting plug-in solar, with more expected soon. Low-income households, renters and temporary workers facing high electricity bills welcome it as a low-cost, portable solution, though industry figures say business models remain unclear and technical and regulatory issues persist.

Scientists found that E-cadherin, a protein best known as the "glue" holding cells and tissues together, also helps epithelial cells swallow nearby dead cells. Using live zebrafish and mouse embryos, researchers observed cells dramatically reshaping their lower surfaces to engulf cellular debris while keeping upper surfaces stable, allowing protective barriers to remain sealed.

Valve's September Steam hardware survey places Nvidia's GeForce RTX 5070 at the top of its all-video-cards table with 6.15% of surveyed machines, up 2.38 points in a month and ahead of August leader RTX 3060. The same survey shows 32GB is now the most common amount of system memory on a Steam PC, surpassing 16GB.

Nature Medicine lists a randomized, double-blind, active-comparator-controlled phase 3 trial comparing oral small-molecule GLP-1RA safiglipron with dapagliflozin in type 2 diabetes. The feed item provides no further context, so no trial results can be reported.

A Nature Energy piece addresses EU solar and wind power, moving from gigawatt-scale deployment to critical mineral demands. The available context is sparse and offers no further details.

A Nature Sustainability article reports the green synthesis of hydrogen and formaldehyde from methanol with enhanced quantum efficiency. The provided context is sparse, so specific methods and detailed results are not stated in the available information.

A NASA-published feature spotlights Richard Spolzino and examines gaps in the agency's return to the Moon. In the article, Spolzino describes chasing the ability to point at a rocket launch and say his work made it possible.

OpenAI published a list of practices it says should govern a frontier training run, opening with the position that structured safety documentation should be required before continuing any frontier reinforcement learning training run, and that each senior leader should be able to veto a run. The supplied context is truncated on operational details.

Two Steam Frame owners report that the Chaperone safety grid, which keeps them from walking into furniture, stops appearing once they start streaming from a PC. An account carrying Valve's developer badge on the SteamVR bug report forum has thanked the owner for the report and asked for reproduction steps.

This is an edition of TechCrunch Mobility, a hub for the future of transportation and, now more than ever, the role AI plays in it. The headline references reining in robotaxis, but the supplied context is sparse and contains no specific facts or outcomes.

OpenAI has launched ChatGPT Sites in public beta, hosting a website, web app or game for subscribers on five of its plans. OpenAI's documentation states in writing that Sites does not support data residency or inference residency at launch, a limitation business readers should see before first deployment.

Meta has open-sourced the device SDKs and firmware behind Muse Gadgets, a project that turns an off-the-shelf ESP32 board or a spare Raspberry Pi into hardware its Muse assistant can drive. The exception is the hardware Meta built itself: the Muse Home Link reportedly only runs official firmware and cannot be reflashed.

Professors at the Universidad Carlos III de Madrid (UC3M) and the Universidad Pública de Navarra (UPNA) have developed a soft robotic gripper that can pick up and hold objects, and also manipulate and reposition what it holds between its fingers without losing its grip. Rubber ducks and screwdrivers were used to test it.

A columnist writes that cyber and physical security threats are rapidly evolving, and argues that robotics and physical AI can evolve to meet them responsibly. The piece is an opinion column; no specific results or deployments are reported.

OpenAI's Codex can now read a GitHub pull request inside ChatGPT and help write the review. Its documentation carries a warning that posting in the Summary or Changes fields sends the comment to the source provider immediately, without waiting for the Submit review step.

In a small trial, high-dose vitamin B3 (niacin) added to standard glioblastoma treatment showed early promise, with 82% of patients remaining progression-free after six months. Researchers believe niacin may help revive immune cells suppressed by the cancer, but larger studies are still needed to confirm the benefit and safety.

Valve says the Steam Frame can stream over plain Wi-Fi without the wireless adapter, provided the router is wired directly to the PC. The company recommends using a 5GHz router and notes this is similar to how Quest handles Wi-Fi streaming.
