I think it’s very likely we’ll see companions to isolated planetary mass objects (IPMOs) in the coming years and it raises the question what the hell to call them. The current IAU definition makes it clear that IPMOs are not “planets” and suggest “sub-brown dwarfs” (arxiv.org/pdf/2203.09520)

The most sensitive search for exomoons ever - moons 2.5x smaller than Europa are excluded! And around a temperate Earth-sized planet to boot. What’s really neat is that, for the first time, we can confidently say another Earth does not enjoy total Solar eclipses. arxiv.org/abs/2609.05301

"However, no IAU definition of exomoon exists, but the need will likely grow as companions are inevitably found in conditions foreign to that observed in the solar system."

A particle made of force? Chinese researchers claim they've definitively detected a "glueball"--a particle of bound gluons, which carry the strong force. Gluons bind together protons & neutrons, but they can also stick to each other. No ordinary matter required. 🧪 www.science.org/content/arti...
The Beijing Spectrometer III has provided evidence for glueballs, which are made almost entirely of force-carrying particles.

YouTube is really having a moment about AI. There is enormous anti-AI sentiment and yet simultaneously widespread AI use at various levels. I don’t think academia has quite had that moment yet, but it mirrors YT with AI-slop papers, reviews, proposals, etc and anecdotally ubiquitous use.

I find myself confused here. The new object is in orbit around a star. It’s a planet, not a moon. The fact that that star is in orbit around another star seems neither here nor there. 🔭

Prices keeps rising. When will this AI-driven age of abundance manifest? The problem I see is that heavily indebted governments (basically all of them) would oppose abundance as it’s deflationary. They want to inflate away their debt. Because we borrowed so much, we’re trapped with rising prices.

Are folks excited about SpudCell? Whilst an impressive technical feat, I have to question how much precisely engineered cells reveal about the natural propensity for abiogenesis. Of course it does guide us about the minimal set needed for life, but that feels like a much smaller prize.

At the end of the day, this visualization shows what's driving the rising risk of these dangerous heat waves. It's the human-caused burning of fossil fuels and the resulting increase in greenhouse gases. That's it. More climate change indicators: zacklabe.com/climate-chan...
This graphic shows four line graph time series and each are monthly from January 1984 through May 2026. The first graph is a 12-month running mean of global mean surface temperature anomalies. Anomalies are computed relative to a 1991-2020 baseline using ERA5 data. The second graph is monthly carbon dioxide abundance. The CO2 graph is the Keeling Curve. Current levels are 432 ppm. The third graph is monthly global methane abundance. Current levels are 1940 ppb. The fourth graph is monthly global nitrous oxide abundance. Current levels are 340 ppb. The three greenhouse gases show seasonal cycles and long-term increasing trends using data from NOAA GML. The global mean surface temperature anomaly record also exhibits decadal variability and a long-term increasing trend. All graphs are rising and shown in four different colors, including white, yellow, orange, and pink.

A bizarre thing I’ve noticed being back in the UK this year is that drivers are quite happy to turn into a sideroad at full speed when a pedestrian is halfway through crossing it & fully expect that pedestrian to stop in their tracks to avoid being run over. NY drivers are way more pedestrian aware.

With the two-hour marathon now broken, I wondered: how fast could humans ultimately run a marathon? Between a simple exponential and a stretched exponential model, the latter is favored implying humans could run 1h47m (!) one day (assuming same rules/no cheating).
