We cannot believe we’re saying this… with profound sadness we share that Philip Anthony Campbell has passed. Motörhead’s guitarist for 31 years, Phil later formed @PCATBS with his sons Todd, Dane, and Tyla. A brilliant guitarist with a huge heart and unstoppable humor. RIP Phil.

Terrible news. I'd heard was undergoing some kind of treatment. Unfortunately, it didn't go well. Motörhead's members are continuing to go. Lemmy, the Philty Animal, Fast Eddie, Wurzel and now Phil. Only Mikkey Dee is left of the long time members plus a few shorter time members.

China is testing a vacuum high-speed train that can travel over 1,000 km/h. This ultra-fast vacuum tube magnetic levitation system could reduce the travel time between Shanghai and Hangzhou (distance: 200 km) to just 9 minutes.

Japan has a new stationmaster cat. The Wakayama Electric Railway Kishigawa Line is famous for its feline stationmasters. A new cat, Rokutama, has been appointed trainee stationmaster of 2 stations. Other cats received promotions. This is serious stuff.

We are hiring a Head of Preparedness. This is a critical role at an important time; models are improving quickly and are now capable of many great things, but they are also starting to present some real challenges. The potential impact of models on mental health was something we saw a preview of in 2025; we are just now seeing models get so good at computer security they are beginning to find critical vulnerabilities. We have a strong foundation of measuring growing capabilities, but we are entering a world where we need more nuanced understanding and measurement of how those capabilities could be abused, and how we can limit those downsides both in our products and in the world, in a way that lets us all enjoy the tremendous benefits. These questions are hard and there is little precedent; a lot of ideas that sound good have some real edge cases. If you want to help the world figure out how to enable cybersecurity defenders with cutting edge capabilities while ensuring attackers can't use them for harm, ideally by making all systems more secure, and similarly for how we release biological capabilities and even gain confidence in the safety of running systems that can self-improve, please consider applying. This will be a stressful job and you'll jump into the deep end pretty much immediately. openai.com/careers/head-of-p…

My CISO called me at 3 AM last Tuesday. "We caught someone." I asked, "Caught them doing what?" He said, "Typing." Let me explain. We have an employee in IT. Great worker. Always online. Never complained. Perfect Slack etiquette. One problem. His keystrokes were arriving 110 milliseconds late. One hundred and ten milliseconds. That's 0.11 seconds. The average American remote worker has 20-40ms of latency. This guy? 110ms. Every. Single. Keystroke. My security team ran the numbers. That latency doesn't come from a bad router in Ohio. That latency comes from Pyongyang. Our "Senior DevOps Engineer" was a North Korean operative. Running his work laptop through a laptop farm. In America. While he worked from a government building. In North Korea. He passed the interview. He passed the background check. He passed the vibe check. He did not pass the speed of light. Here's what people don't understand about physics: Light travels 186,000 miles per second. But it still has to go through China. And China adds latency. Since April, Amazon has caught 1,800 of these attempts. Eighteen hundred. I called an emergency meeting with my board. I said, "We need to implement Keystroke Velocity Auditing across all remote employees." They said, "That sounds invasive." I said, "You know what else is invasive? The Democratic People's Republic of Korea in your Jira tickets." They approved the budget. We now monitor keystroke timing to the microsecond. If your latency exceeds 60ms, you get a call from HR. If it exceeds 100ms, you get a call from the FBI. We've already flagged 47 employees. Turns out 44 of them just have bad Wi-Fi. 3 of them are "still under investigation." The lesson? You can fake a resume. You can fake a background check. You can fake an American accent on Zoom. But you cannot fake the speed of light. Physics is the ultimate background check. Hire accordingly.

The Signal developers are now hostile actors against the UK. As if they needed more of an ego boost.

A new organ has been found behind your nose. For centuries, every anatomy textbook swore there were only three pairs of major salivary glands. Turns out the books were wrong — and the missing ones were hiding in plain sight. In 2020, Dutch researchers scanning head-and-neck cancer patients with a cutting-edge PET/CT technique (PSMA PET-CT) noticed an unexpected glow deep in the nasopharynx, right where the nasal cavity drains into the throat. No textbook had ever marked a salivary gland there. They double-checked: 100 consecutive patients → same structure in every single one. Then they dissected two fresh cadavers and there they were: a previously unknown pair of macroscopic salivary glands, roughly 3.9 cm long, draped over the tubarium (the cartilage of the Eustachian tube). The team named them the tubarial glands. Their job? Keep the upper throat and the back of the nose moist during talking, swallowing, and breathing — an area that gets painfully dry after radiation. Here’s why this matters: radiation oncologists had never been told to spare this spot. The researchers re-analyzed treatment plans from 723 patients and found the more radiation the tubarial region received, the worse the toxicity — more trouble swallowing, thicker saliva, constant dry mouth. A simple anatomical blind spot had been quietly worsening outcomes for years. Now that we know these glands exist, new radiation protocols can shield them, giving thousands of head-and-neck cancer patients an easier road to recovery. [Valstar, de Bakker, et al., “Discovery of the tubarial salivary glands: a new organ at risk in radiotherapy for head and neck cancer,” Radiotherapy and Oncology 2021, DOI: 10.1016/j.radonc.2020.09.034]

Archaeologists, have any of you seen these in person?? This is really grave news.
Nearly 700 sinkholes have appeared in parts of Turkey, with new ones showing up, fueled by extreme drought.
