Astronomy Picture of the Day (APOD) has an image of a star which turns out to be a double star, seen only with telescopic aid. It includes the visible spectrum of both stars which shows how different the two stars are.
The image is lovely and the explanation adds to the pleasure of seeing it as well as in not misunderstanding what you are seeing.
For stargazers, planet watchers, the constellation savvy, the scientific term "asterism" is well known. I'd never heard of it --not included in the explanation which gave me an idea of what a common term it is -- and Wiki explains the term. The explanation also includes a comment on how astronomers/astrophysicists reason.

Lava Study: Lab and Field
Environmental & Science Education, STEM, Earth & Space Science, Earth Systems, Geology, Nature of Science
Ed Hessler
This video (11m 45s) from #ScienceInsider is about how scientists study lava. Of course they collect samples but how and where? There is more to the study of volcanology than doing field work. There is the laboratory, too and I very much like how the video bring field and lab work together.
The Syracuse University Lava Project is included and represents the laboratory side of the study-of-lava equation, science practices in action. An interesting aspect of the Lava Project is that it is a result of a collaboration between sculptor Bob Wysocki (SU Department of Art) and geologist Jeff Karson (SU Department of Earth Sciences). The page is well worth taking a look at.

Animals and Earth Quake Predictions
Environmental & Science Education, STEM, Earth & Space Science, Earth Systems, Behavior, Biodiversity, Geology
Ed Hessler
The second of two presentations by Sabine Hossenfelder on earthquake prediction, she discusses short-term forecasts, "from months to seconds. In this one she again calls attention to their human toll. "[E]arthquakes are the most fatal natural disasters. In the two decades from 1998 to 2017, they killed more than 700 thousand people." Then she asks,
"So what are seismologists doing to warn people of earthquakes? Can animals sense if an earthquake is coming? And what are earthquake lights? That’s what we will talk about today. ... Short-term predictions don’t help with infrastructure investments, but they give people time to evacuate."
The non-seismic precursors may attract your attention because those involving animals are commonly reported. First, Hossenfelder includes a discussion of several short-term physical precursors "that are fairly well established though not all are well understood before she turns her attention to animals.
She ends by talking about the "heavy burden" that comes with predictions, i.e., when they are wrong. She makes a suggestion that seem a worthy and important component of any prediction.
The video can be watched on YouTube but I like being able to read the text along with listening.

6000 Years of Forest Landscapes and Sounds, United Kingdom Interactive

The story of the world's woodlands is one of overwhelming decline, " writes Sophie Yeo for Inkcap Journal in the introduction to Six Thousand Years of Forests, an amazing visual and aural interactive featuring the declines in United Kingdom (UK).
Yen's short introduction concludes with this observation. "The primeval forests have given way to an intensively farmed and settled landscape. Today, just 13% of the UK is covered by woodland, of which only 2.5% is more than 400 years old. If this was ever a woodland nation, it is not anymore."
By scrolling you can "see how land use has changed across the last eight millennia." "Anthromes" short for Anthropogenic Biomes, or Human Biomes, are the globally significant ecological patterns created by sustained interactions between humans and human patterns created by sustained interactions between humans and ecosystems, iincluding urban, village, cropland, rangeland and seminatural anthromes." (see here).
Viewers comments include words and phrases such as "Fabulous,:"a creative re-telling," and"Amazing." Oh yes, these and more accolades. One comment critical of the work must have run, not walked through the forest depictions," with Yeo responding "the second paragraph makes that very point, with a link to the very study that you have included in your comment."
The Inkcap Journal is longform journalism about nature and conservation in Britain. Members can receive a free weekly digest every Friday on nature news in Britain. Yeah, I know that all this information about the journal is in the masthead of today's feature but if, like me, you wanted to start hiking, it is easily missed. I lumbered right by it the first time.

The Threat of Forever Chemicals

Ed Hessler
PFAS. "per- and polyfluoroalkyl chemicals...are long-lasting-compounds that ...have been linked to cancer, liver damage, thyroid disease, and other ailments." Now that is a worrisome list and the issue is they show up in nearly everywhere, e.g., soil, ground water, drinking water sources, even rainfall." In other words, you can't hide from them. "By some estimates, this toxic family of chemical can be found in the blood of nearly every person on the planet.
Their uses include firefighting foams, waterproof clothes and nonstick cookware.
They are commonly called "forever chemicals," with reason.
CBS Sunday Morning correspondent Lee Cowan provides a tour of how they became so ubiquitous, "and talks with families, farmers, and health advocates fighting for clean, save water."
The video is 11m 21s long.
