We study the processes that shape landscapes on Earth and other planets.

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

[Massachusetts Institute of Technology (MIT) @MIT]

A new technique uses remote images to gauge the strength of ancient and active rivers beyond Earth. The approach allows geologists to see how intensely rivers once flowed on Mars, and how they currently flow on Titan, which is Saturn’s largest moon. https://t.co/W5JO3lpF8V

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. https://t.co/FbvWFnotKT

"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 https://t.co/P7MJp7s4br

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 https://t.co/LrHixgIyp6

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 https://t.co/LrHixgJ6eE

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

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. https://t.co/DQgoF2Q9bJ

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. More info and ordering options here: https://t.co/NjBrk949St

Flowing sediment shapes landscapes. New research by @EricDealFluvial and others helps scientists better predict the process.

This week in @Nature, @EricDealFluvial shows how grain shape matters in sediment transport. Work with Ken Kamrin, @VendittiLab, @s_j_benavides. https://t.co/gEXe05J2Ag

[The Perron Group at MIT @MITgeomorph]

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. https://t.co/lg77EglrLZ
