    “The Chiribiquete are table top mountains located deep in the Colombian Amazon and host many rare endemic species. Helanlin Xiang's work shows that the Chiribiquete Mountains likely upifted before the Early Miocene and could have acted as a long-lived stepping stone, connecting species in the Andes with the Guyana Shield…”

  6. Former #DOJ special counsel #JackSmith is set for a closed-door interview with #House #Republicans Wednesday after lawmakers rebuffed his offer to testify publicly about his investigations into #Trump.

    The private #deposition is part of an ongoing investigation by the Republican-led House #Judiciary Cmte into the DOJ’s #criminal inquiries of Trump during the #Biden admin.

  7. The Balvenie

    Photographer Ernie Button explores the stains left behind when various liquors evaporate. This one comes from a single malt scotch whisky by The Balvenie. The stain itself is made up of particles left behind when the alcohol and water in the whisky evaporate. The pattern itself depends on a careful interplay between surface tension, evaporation, pinning forces, and internal convection as the whisky puddle dries out. (Image credit: E. Button/CUPOTY; via Colossal)

  8. Permafrost Formation In A Meandering River Floodplain

    doi.org/10.1029/2024AV001175 <-- shared paper
    --
    “... KEY POINTS:
    • River meandering resets permafrost development and vegetation succession by eroding old floodplain areas and depositing new land
    • On the Koyukuk River, permafrost rapidly forms in new deposits, but it takes over 4 Kyr to develop to its full areal extent of 85%
    • The rate of permafrost formation is likely linked to vegetation succession on younger and overbank deposition on older floodplain areas…”

  9. The filing also includes newly public comments made by other #Fox hosts….

    In a Dec 2020 message w/ #FoxNews host #GregGutfeld, #JesseWatters nodded to the potential upside of aligning w/ those claiming the election was stolen. “Think about how incredible our ratings would be if Fox went ALL in on STOP THE STEAL.”But he #testified in a #deposition that he saw “no evidence that #Smartmatic Technology switched votes in the 2020 Election in the United States.”

  10. …despite some internal concerns about Pirro’s commentary about the election, #FoxNews CEO #SuzanneScott told a network executive “we don’t want to censor” her show, acc/to the filing.
    
Still, acc/to #Smartmatic, #JeaninePirro acknowledged in a #deposition that the 2020 election WAS NOT STOLEN. She agreed that the election was “fair & free” & that Smartmatic, which provided #election #technology to Los Angeles County, did nothing wrong.

  17. Quick-Drying, Fast-Cracking

    Water droplets filled with nanoparticles leave behind deposits as they evaporate. Like a coffee ring, particles in the evaporating droplet tend to gather at the drop’s edge (left). As the water evaporates, the deposit grows inward (center) and cracks start to form radially. After just a couple minutes, the solid deposit covers the entire area of the original droplet and is shot through with cracks (right).

    Researchers found that the cracks’ patterns and propagation are predictable through a model that balances the local elastic energy and and the energy cost of fracture. They also found that the spacing between radial cracks depends on the deposit’s local thickness. Besides explaining the patterns seen here, these cracking models could help analyze old paintings, where cracks could hide information about the artist’s methods and the artwork’s condition.

The federal agency complained, in filing today that Musk canceled deposition at the last minute, which cost the SEC time & money. #SEC has been #investigating whether Musk or anyone else working with him committed #securities #fraud in 2022 as he sold shares in #Tesla and began shoring up his stake in Twitter cnbc.com/2024/09/20/sec-says-m
