The backstory on Sam's paper from @MIT @ScienceMIT

Story by @isaac_schultz_ for @Gizmodo gizmodo.com/lifespans-rive…

New in @PNASNews: Sam Birch estimates river flow and sediment transport rates on ancient Mars and present-day Titan using only channel width and slope. doi.org/10.1073/pnas.2…

"If we can understand the geologic factors that contribute to biodiversity, we can do a better job of conserving it," says @eapsMIT professor Taylor Perron news.mit.edu/2023/river-ero…

7/7 This mechanism could have increased freshwater biodiversity elsewhere in the Appalachians, and in other ancient mountain ranges. A collaboration with @TJNear @DaeminKim3 @TVAnews @hybridActinop @BenavidBolivia @juliawood527 @yalepeabody @eapsmit doi.org/10.1126/scienc…

6/7 The order in which fish populations would have been isolated by this geological mechanism matches the order implied by genetic data.

New in @sciencemagazine: Maya Stokes shows how rivers eroding through different types of rocks help explain high freshwater biodiversity in old mountain ranges like the Appalachians. With @TJNear @DaeminKim3 @TVAnews doi.org/10.1126/scienc…

The backstory from @MIT @ScienceMIT news.mit.edu/2023/river-ero…

Sediment transport rate depends on how many grains are in motion and how fast they are moving. Santiago Benavides @s_j_benavides shows that when bedload flux is on-off intermittent (punctuated by rare, large bursts), it's because of the "how fast" part. doi.org/10.1029/2022GL…

Mrs. @MITgeomorph, a.k.a. @LisaVPerron, has been busy writing books for children. Her debut, out today, has some beautiful landscapes and other charismatic patterns from the natural sciences.

Flowing sediment shapes landscapes. New research by @EricDealFluvial and others helps scientists better predict the process. Comments from Christophe Ancey @EPFL, story by @ClarissaWrights  eos.org/articles/decod…

This week in @Nature, @EricDealFluvial shows how grain shape matters in sediment transport. Work with Ken Kamrin, @VendittiLab, @s_j_benavides. nature.com/articles/s4158…

Our paper about grain shape is featured on the cover of @Nature. Led by @EricDealFluvial, with @VendittiLab, @s_j_benavides, @RiverProfile, Ken Kamrin & Qiong Zhang. nature.com/nature/volumes…
