CoMaps is open-source community-oriented privacy-first navigation app for mobile devices. It is currently choosing its fiscal / umbrella host which would be most aligned with those goals, so if you have opinions, come vote at https://codeberg.org/comaps/Governance/issues/166

Poll on umbrella host
Dear members of the CoMaps community. After we've [investigated a large number of potential umbrella hosts](https://codeberg.org/comaps/Governance/wiki/Umbrella-Orgs) that could potentially fit as a host organisation for the project, we've now narrowed it down to two alternatives that we think wo...

"We’re delighted to announce the first #GalaxyZoo workflow to include images from the NSF-DOE Vera C #Rubin Observatory, using #galaxies drawn from its first Data Preview": https://blog.galaxyzoo.org/2026/05/12/a-first-galaxy-zoorubin-project/ - "[t]he new workflow went live on the site just now, but with only 10,359 subjects it won’t stick around for long, so do jump in and get classifying."

News story on a significant earthquake in Uzbekistan, 50 years ago, May 17, 1976 (Fargo-Moorhead Forum archives). Mentions the Medvedev scale, apparently now the the MSK or MSK-64 scale. That scale is not mentioned in North American, physical geology textbooks I have seen, although it's apparently similar to the Mercalli scale.
Also, the first page of a scientific paper on it, from 1980. ⚒️🧪

AI red teaming is not your father's red teaming. As models become agents that can take actions in the real world, red teams are now testing everything from prompt injections and misinformation to autonomous behavior and business-process failures.
Check out my latest CSO feature for more on this trend.

AI red teaming comes of age
As enterprises rush to deploy copilots and autonomous agents, security teams are discovering that testing AI systems requires skills, tools, and assumptions that traditional red teaming was never designed to provide.

Abstract: Using integral field spectroscopy, we explore the disk-halo interface, or the inner circumgalactic medium (CGM), of individual galaxies by constructing and analyzing emission-line maps for a large sample (72) of normal, low-redshift galaxies spanning three orders of magnitude in stellar mass and four orders in star formation rate (SFR). We find a steep turnover occurring at $(1-2) R_e$ in the H$\alpha$, [O {\small II}], and [O {\small III}] line emission radial profiles. Beyond this radius, the slope of the line emission radial profiles becomes shallower as the SFR of the central galaxy decreases, which might reflect the strength of the feedback processes. The line emission fluxes at large radius ($(5-10) R_e$ or $\sim (0.1-0.25)r_{\rm vir}$) correlate with the galaxy's SFR, but not with its stellar mass. These findings suggest that ionizing photons escaping from star-forming regions in the central galaxy account for the observed emission line fluxes from the inner CGM, with escape fractions inferred from the [O {\small III}] and [O {\small II}] ratio. Different state-of-the-art theoretical models do not agree on the predicted dependence of cool gas on the SFR of the central galaxies, highlighting the importance of CGM emission line measurements to distinguish between different subgrid models for star formation and feedback processes.
