”The novelty of our method is using clay to make the biological pump more efficient—the zooplankton generate clay-laden poops that sink faster,” Clay dust method turns CO₂ into food that zooplankton expel into the deep sea I saw endless copepods in the samples we had to pick through for larval cod but I never expected …

Bizarre
The gazelle walked right by the croc. I can’t believe the gazelle was that foolish. Plus gazelles usually travel together. I hope this wasn’t staged.
Falcons help people
“Our review highlights that peregrine falcons might serve as valuable models for investigating the impact of environmental contaminants on human health,” says Antonio Giordano, M.D., Ph.D., Founder and Director of SHRO and Professor at Temple University. By studying the effects of pollutants on these birds, researchers can draw parallels to human health risks, fostering collaboration …
Complexities of Starling Murmurations, etc.
Cooper’s professional background in physics and bioinformatics—a data science applied to biological systems—led her to study of the dynamics of networks. She uses a 19th-century photographic technique called chronophotography to reveal what she describes as “the robustness of self-organised systems in nature.” Complexities of Starling Murmurations Neat pix of murmurations. Red-winged black bird murmurations above the sandhill …
First direct evidence that ancient Americans relied primarily on mammoth
Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction of large ice age mammals. Isotope analysis reveals mammoth as key food source for ancient Americans …
Peregrine Falcons and Prey

Dog Brains and News
Dogs with bigger brains relative to their bodies aren’t necessarily smarter, a new study finds. The research, published Nov. 13 in the journal Biology Letters, suggests that while working dogs may have more complex abilities compared with other breeds, they’re organized into a more compact space in the brain. This differs from what’s seen in evolutionary …
Fremont Ellis, “New Mexico Valley – Cimarron”
Nothing is better on an autumn day than a stroll on a picturesque mountain trail. Fremont Ellis, “New Mexico Valley – Cimarron”, c. 1928-30 American Museum of Western Art-The Anschutz Collection Ellis had a good rep as a SW artist. I like this one even if it is a little dark.
Virtual fences for ranchlands
Additionally, in the virtual fence areas, the researchers found a greater variation of vegetation heights compared to the fenced rangeland. This transitional zone could help increase native habitat for pollinators and birds. Olsen notes that while virtual fences can help create stronger ecosystems, they can also help ranchers. Fences require time, money and labor to …
Cock fight
Rémy Cogghe, Belgian painter (1854–1935)Cockfight in Flanders Steve wrote about this in Querencia and maybe elsewhere. He was more favorable to it than many. I think he saw it as more of a social occasion than a sport. Having had much loved Barred Plymouth Rocks when I was 10 I would rather see them …
