An active rift in the African continent has reached a “critical threshold” and will break apart soon. "We found that rifting in this zone is more advanced, and the crust is thinner, than anyone had recognized," says Christian Rowan, a geoscientist at Columbia University. Here’s more from @ScienceAlert@flipboard.com, including just how soon “soon” means: https://flip.it/0HeDb2 #Science #Africa #Geology #Earth #Nature

#PPOD: The colors in this image from the NASA/ESA Hubble Space Telescope tell a story about density in the Trifid Nebula, a star-forming region about 5000 light-years from Earth. The top left, where it is bright blue, has the least dust. Here, powerful ultraviolet light stripped electrons from nearby gas, creating a glow, with winds creating a bubble by clearing out surrounding dust. Credit: NASA, ESA, STScI. Processing: J.

I'm still struggling to find my footing here on Mastodon. A bit with the platforms and tags, but mostly finding people to follow. I'm a bit all over the place, posting about my #writing, be it academic or fiction (mostly #SciFi), and about cool #Science I ran into, and the more common than it should be - complain about stuff. I'm interested in #SFF, #publishing, #MiniaturePainting, science, #queer culture, academia, human sexuality, geekish humor, #comics & #EarthSci. Recommend people to me!

"On a été étonnés" : ce que révèlent dix ans de "zéro pesticide" sur des cultures soi-disant dépendantes du "parapluie chimique" "Une étude sur dix ans coordonnée par l’#Inrae, dont les résultats viennent d’être publiés, montre que l’on peut se passer totalement de #pesticides dans les grandes cultures (blé, colza, orge, betterave…) tout en obtenant des rendements satisfaisants et en préservant la viabilité économique des exploitations.". #Science #Société #agriculture #AgricultureIntensive #environnement #SantéPublique pollution eau https://www.lamontagne.fr/paris-75000/economie/on-a-ete-etonnes-ce-que-revelent-dix-ans-de-zero-pesticide-sur-des-cultures-soi-disant-dependantes-de-la-chimie_14973868/

The Trump administration has terminated more than 100 advisory committees to #science agencies and reduced the transparency and independence of those that remain. https://www.nature.com/articles/d41586-026-01301-5

I’m glad to share my paper on publication activity and migration trends of Ukrainian SSH scholars during the first two years of the full-scale war. 👉 https://www.jscires.org/article/15/1/124 The key finding: the most productive researchers have largely remained in #Ukraine and many have maintained or even increased their publication activity, despite the challenges. #Science #OpenScience #Bibliometrics #HigherEducation #Scientometrics #Research #Academia

The White House announced a plan to cancel over 50 #space missions as part of a devastating 46% cut to #NASA #science.

The proposal would likely eliminate thousands of jobs at an agency that has just launched astronauts to the #Moon for the first time in decades, and dozens of other space missions would see their operations reduced or slowly wound down to a halt.

The following missions are to be cancelled:

  1. The Habitable Worlds Observatory being built to search for #life on dozens of Earth-like planets beyond our Solar System while addressing fundamental questions about our #Universe.

  2. OSIRIS-APEX capitalizes on the exceptionally rare 2029 Earth flyby of the potentially hazardous #asteroid #Apophis to advance planetary defense strategies and reveal how Earth’s #gravity alters an asteroid’s surface and interior.

  3. The ExoMars Rosalind Franklin rover will deliberately search for signs of life on #Mars by analyzing the composition of samples collected from as deep as 2 meters below the surface.

  4. The DAVINCI mission is an atmospheric probe that will be deployed to our sister planet, #Venus, and provide the first detailed measurements of the composition and chemistry of its #atmosphere.

  5. Initially focusing on #Jupiter’s interior, atmosphere, and aurora, #Juno is already orbiting Jupiter and has expanded during its extended mission to be a full system explorer capable of investigating the Galilean satellites, rings, inner moons, radiation belts, and boundaries of Jupiter’s magnetosphere.

  6. VERITAS will create unprecedented, global, high-resolution datasets of Venus designed to answer a fundamental question for rocky #planets: how did Earth and her twin Venus evolve into two entirely different examples of planetary #habitability?

Stalin fundamentally crippled Soviet #science in the 1930s and almost a century later it still hasn't recovered. That's what Trump, RFK Jr., Vought, and MAGA are doing right now to the United States.

I had an interesting discussion over beer with a colleague last week, we’re both seismologists. The topic was, given the hostility toward science of the current regime and the difficulty of obtaining funding, how do we keep the science alive and moving forward? One idea we had is to encourage and support independent scientists, who in a less-enlightened age would have been called “gentlemen scientists.” The concept would be to give interested people of independent means (e.g., retired) and STEM backgrounds the opportunity to do science in collaboration with scientists on campus. There would be shared office space, and independent scientists could at their discretion spend time on campus and meet with scientists and technicians to evaluate ideas and design experiments. They would presumably collaborate with full-time scientists to learn the current state of the science and the ins and outs of peer review and publishing. As an example, much of seismology is signal processing; anyone with a background in signal processing (EE degree?) and even a rudimentary ability to code could produce real, useful science. I would welcome any commentary here. Do you think people would be interested? If so, how do we reach them and invite them to participate? Also: I’m not in love with the designation “independent scientist”, do you have suggestions for something better? #Science
