#FAIR enough.
(referring to purlz.org/ ; it's known that it doesn't work any longer, it's just ironic it's still in the list on the FAIR page)

The image is a list of services that supply globally unique and persistent identifiers. The heading reads “Example services that supply globally unique and persistent identifiers”. Below this are bullet points listing these services and their corresponding URLs. The first bullet point states "Identifiers.org provides resolvable identifiers in the form of URLs and CURIEs: http://identifiers.org". The second bullet point states “Universally unique identifier: http://en.wikipedia.org/wiki/Univer…
An image depicting a 404 error page from Google. The page features the Google logo in blue at the top left corner. Below the logo is the text "404. That's an error." and underneath that, “The requested URL was not found on this server. That’s all we know.” To the right of the text is a cartoon-style drawing of a disassembled robot, with various parts scattered around it, including a head, arms, legs, and cylindrical components. The robot appears to be broken or taken apart, and the overall aest…

Cloudy with a chance of starshine: Possible photometric signatures of nebular-dominated emission in $1.5 < z < 8.5$ JADES galaxies
The discovery of high-redshift galaxies exhibiting a steep spectral UV downturn potentially indicative of two-photon continuum emission marks a turning point in our search for signatures of top-heavy star formation in the early Universe. We develop a photometric search method for identifying further nebular-dominated galaxy candidates, whose nebular continuum dominates over the starlight, due to the high ionising photon production efficiencies $ξ_\mathrm{ion}$ associated with massive star form…

Organic geochemical evidence for life in Archean rocks identified by pyrolysis–GC–MS and supervised machine learning: #life in ancient rocks: gizmodo.com/ai-uncovers-eviden / reuters.com/science/new-method - a machine-learning-enhanced approach to chemical analysis is drastically expanding the chemical record of life on Earth, and it could help us find evidence of life on other planets too.

Confirming Near- to Mid-IR Photometrically-Identified Obscured AGNs in the JWST era
We evaluate the underlying assumptions for the identification of Active Galactic Nuclei (AGNs) through near- and mid-infrared photometry and spectral energy distribution (SED) fitting out to z ~ 3. For massive galaxies, log(M) > 9.5, our high resolution spectra of the rest optical range generally confirm the results of SED fitting, which relies primarily on excesses above the stellar emission between 1 and 6 microns to identify AGN. However, the method is undermined if the redshift used for the…
