Nobel Prize for Quantum Tunneling Breakthrough - DTNS 5120

OpenAI Dev Day brings broader app integration support into ChatGPT, and a fitness sensor kit by Output Sports that replaces expensive diagnostic equipment.

Starring Jason Howell, Tom Merritt, and Darragh Whelan.

JASON: This is the Daily Tech News for Tuesday, October 7, 2025. We tell you what you need to know, follow up on the context of those stories and help each other understand.

TOM: Today Darragh Whelan tells us about a small fitness sensor kit that replaces large and expensive diagnostic equipment, and quantum physicists get a Nobel prize for their work.

I’m Jason Howell,

I’m Tom Merritt.

JASON: Let’s start with what you need to know with the big story.

BIG STORY

Nobel physics prize awarded for pioneering experiments that paved the way for quantum computers

JASON: The Royal Swedish Academy of Sciences awarded the Nobel prize for Physics to John Clarke, Michel Devoret, and John Martinis for their experiments that demonstrated quantum tunneling in an experimental electrical circuit. Tom, what the heck does that mean?

TOM: I don’t know either. But here’s what I do know. Quantum tunneling is a phenomenon where a subatomic particle can appear on the other side of a solid barrier. The demonstration used superconducting wires, which have no resistance, interrupted by an insulator that normally impedes the flow of particles like electrons. The interrupted wire is called a Josephson junction. The scientists cooled the wire, which should reduce the number of electrons that can break through the insulation. However, if quantum tunneling is happening, after a certain point, the flow does not reduce. That's what they found. This principle is used in the creation of quantum computers. It's also used in superconducting quantum interference devices, or SQuIDs, which can measure small variations in a magnetic field. It can be used to find minerals below the surface of the Earth or detect the source of epileptic seizures in the brain. It's also used in flash memory and other transistors.

BRIEFS

OpenAI wants to make ChatGPT into a universal app frontend
Ars Technica
TOM: Yesterday was the start of OpenAI Dev Days and during the keynote, CEO Sam Altman announced a few new products for ChatGPT users and developers.

OpenAI launched an SDK that turns ChatGPT into an app frontend platform. It's built on the popular open-source Model Context Protocol (MCP), meaning developers can create full-featured apps directly within ChatGPT conversations. Those integrations will happen entirely in the chat environment with interactive UI elements, real-time context sharing, and overlaid chat functionality. Launch partners include Spotify, Canva, Zillow, Expedia, and Booking.com. Uber, Doordash, Peloton, and Target are coming soon.

JASON: OpenAI also introduced AgentKit, a simplified GUI for creating specialized chatbots with a drag-and-drop building block style interface called ChatKit. The platform includes performance measurement tools, testing workflows, pre-built widgets, and information sources.

OpenAI also announced updates for its Codex coding agent, including Slack integration and improved SDK support. Sora 2, GPT5-Pro, and a smaller and cheaper version of its Real Time audio interface are also now available via API.

OpenAI also teased an "agentic commerce protocol" for instant checkout with monetization details yet to be announced.

US Supreme Court allows order forcing Google to make app store reforms
Reuters
JASON: The US Supreme Court denied Google's request for a partial stay of Judge James Donato's order that requires significant changes to its Play Store, as part of last year's Epic Games' antitrust lawsuit. Court-ordered changes are now required to go into effect by October 22, 2025. That includes allowing developers to use external payment links, informing users about alternative payment methods, and setting their own prices. Google must also stop sharing revenue in exchange for Google Play exclusivity or preinstallation. A July 2026 deadline is set for Google to open its app store catalog to competitors and enable third-party app stores inside of the Play Store. Google plans a full Supreme Court appeal by October 27.

Qualcomm is acquiring DIY electronics platform Arduino
The Verge
TOM: Qualcomm has agreed to acquire Arduino, the Italian open-source electronics platform that has been celebrated by hobbyists and educators. Qualcomm promises to keep Arduino's brand intact as well as its mission, but give it extra leverage with Qualcomm's tech portfolio. Arduino is also launching the Uno Q, a single-board computer powered by Qualcomm's Dragonwing QRB2210 chip running Linux Debian. The computer supports lightweight AI models and is preinstalled with App Lab, an "all-in-one development environment" for managing AI models, Python scripts, and Arduino Sketches. The Uno Q is available for pre-order today for $44.

California law forces Netflix, Hulu to turn down ad volumes
Politico
JASON: California signed a bill into law requiring streaming video services not to “transmit the audio of commercial advertisements louder than the video content the advertisements accompany.” US federal rules made in 2010 capped ad volume on cable and broadcast TV, but do not cover streaming. This bill closes that loophole in California. Content makers initially opposed the law, fearing legal action over the fixes they adopted, but the bill was ultimately reworked to include protections against private lawsuits. This move may set a precedent for other states.

Nintendo just released a mysterious animated short
Engadget
TOM: Nintendo released a 4-minute animated short called "Close to You" on the Nintendo Today app with no context around what it is and whether it is a teaser to something bigger. Of course, that has everyone speculating why it exists in the first place. The short is about a baby playing with a magical pacifier with no instantly recognizable characters or notable clues beyond that. Some wonder if this is a tease ahead to the Super Mario Galaxy Movie featuring a young Princess Rosalina. Others are guessing it might be teasing an upcoming Pikmin film, which has not been officially announced.

As Elon Musk Preps Tesla’s Optimus for Prime Time, Big Hurdles Remain
The Information
JASON: The Information is reporting that Tesla's plans to produce 10,000 Optimus robots for internal use by the end of 2025 has been scaled back by "several thousand." Complications related to technical challenges with the robotic hands forced Tesla to reduce its outlook this Summer.

Google hints at a new Nest Hub
The Verge
TOM: Google told The Verge that it will soon launch a new smart display. Well, what Google Home’s Anish Kattukaran said, was they would “continue to invest in that category,” referring to smart displays. They also said a lot about Gemini, so they might rebrand the Google Home Hub, with integrated Gemini AI. The Nest Hub was last refreshed in 2021, and Amazon recently introduced two new Echo Show smart displays so there is plenty to compete against. Kattukaran says it is “definitely committed to smart displays,” and that they’ll “have news to share there soon.”

TOM: Those are the essentials for today. Let’s dive a little deeper.

DIVE A LITTLE DEEPER

JASON: I’ve been sharing conversations from my trip to Dublin, Ireland, where I met with startups pushing the edge of sports tech innovation. Today, we wrap up that series of interviews with my chat with Output Sports co-founder Darragh Whelan, and we talk about how his company is turning elite sports science into something you can fit in your pocket with a powerful and flexible performance-tracking sensor.

HELPING EACH OTHER UNDERSTAND

We end every episode of DTNS by hearing from you. Today, Kevin just has nice things to say.

Hey DTNS Crew, I really enjoyed the monthly recap episode. It was nice to look back and reflect on the month we just had. I liked pulling in AI to get its opinion. Another segment that might be interesting is a “biggest non-tech news story” (and maybe non-political) just to see the big story that didn’t make your lists. Maybe talk about why it didn’t fit your rundown; maybe give some opinions on it. Always love the show!
