Ad Choices, Mathematicians May Have Figured Out How ‘Stone Forests’ Form. The mold for the blocks included arrays of upright metal rods to "seed" the blocks with pores for an even closer approximation.  |  Ex-evangelical. Astronomer Names Massive, Mysterious Hydrogen Trail After Colombia’s Famous River, Tapper: "Why not make efforts to contain it?" Behind the headlines. The block starts out with internal pores and is entirely immersed under water, where it dissolves and becomes a "candy forest" before collapsing. DOI: PNAS, 2020.

OCEARCH founder and ocean explorer Chris Fischer has been working to protect our oceans and the wildlife that inhabits them. Past: Gizmodo. Jennifer Ouellette (born May 17, 1964) is a science writer based in Los Angeles, California. This occurs even in still water. ✨ Optimize your home life with our Gear team’s best picks, from. This drew us into the problem, and we were very excited when we realized the connection to stone pinnacles and stone forests, which have been quite mysterious in their development. They were using simulations and experiments to explore the interesting shapes that evolve in landscapes due to a number of "shaping" processes, most notably erosion and dissolving. Yes, condescending and calling me “babe” will end very well for you. In the future, they hope to further test this formation process under different environmental conditions in the lab, such as how precipitation and surface runoff, or being buried under loose sediment, might affect pinnacle formation. A team of scientists has uncovered new details on how it works. ", Ford is making new Broncos; mockumentary John Bronco has its ideal pitchman, This is what happens when a president politicizes a pandemic. suggest that a similar mechanism is at work in the formation of stone forests, just on a much longer time scale. "Basically, the mineral—or, in our experiments, lollipop candy serving as 'mock rock'—dissolves and the surrounding fluid gets heavy and then flows downward due to gravity. Coauthor Leif Ristroph told Ars that his group at NYU's Applied Math Lab became interested in studying stone forests (technically a type of karst topography) by a somewhat indirect route. They captured the dissolving process by taking digital photographs at one-minute intervals. As a result, "This study reveals a minimal set of ingredients essential to the needle and bed-of-nails motifs," the authors wrote. Poll: Most Trump voters don’t see Covid-19 as an important election issue. We hope our experiments tell a simple 'origin story' behind these landforms.".
