"The biggest (misconception) in general is people think that the mantle is made of magma, or the mantle is molten or liquid.” Earth sciences professor @brenhinkeller.bsky.social discusses misunderstandings about the Earth’s structure with Indy100.

You probably don’t know this about the Earth – and museums get it wrong too

So much is made of scientific discoveries in outer space, as we try to broaden our horizons and explore the surface of Mars, but in reality, many of us don’t know much about things right below our fee...

With some much terrible news, I want to share something positive. This is a spodosol my students made for our soils class back @dartmouthears.bsky.social featuring O-reo horizon, whipped cream E horizon, pudding Bhs and B horizon, and graham cracker glacial till.

New paper on glacial erosion rates and the Sadler effect that came out of a @dartmouthears.bsky.social grad seminar class just out now in Sci Adv! doi.org/10.1126/scia...

Limits to timescale dependence in erosion rates: Quantifying glacial and fluvial erosion across timescales

Globally, glacial erosion rates outpace fluvial, with limits to the biases introduced by measuring across different timescales.

@dartmouthears.bsky.social professor Mathieu Morlighem discusses the risks of an Antarctic ice shelf that broke apart in 2022, and an emerging hot spot along the coast of East Antarctica, via Science News.

An unexpected ice collapse hints at worrying changes on the Antarctic coast

The Conger Ice Shelf disintegrated in 2022. Satellite data leading up to the collapse hint at worrying changes in a supposedly stable ice sheet.

Ever felt the ground tremble, creak, or groan? It turns out that small earthquakes in New Hampshire are somewhat common, according to @dartmouthears.bsky.social professor Leslie Sonder, via NHPR ⤵️

Felt the ground tremble? Yup, earthquakes in New Hampshire are somewhat common

While seismic activity is common, not all earthquakes are easily noticed.

A review in the Washington Post says that Dartmouth professor Darrin McMahon offers a "wide-ranging history" in his new book that "demonstrates that progress toward achieving equality is almost never linear." ⤵️

New research co-led led by Dartmouth anthropologist Nathaniel Dominy suggests that the eyes of Rudolph and his reindeer brethren may have evolved so that they can spot their favorite food during dark Arctic winters, via @BBC. ⤵️ 🎅

Reindeer eyes change colour to help them find food in the winter

The surface of a reindeer's eye changes from golden-orange in summer to a rich blue colour in the winter months. Find out more here.

Let's talk about Ernest Everett Just, a cell biologist who unraveled the mysteries of fertilization in spite of the obstacles he faced as an African-American.

Just's story weaves together good, rigorous science with racism & tragedy.

He was born in 1883 in seaside Charleston, South Carolina.

A scientist studies a research rig. He is pensive and contemplative, with his chin on his fist, observing.

He's a handsome young man wearing a suit and tie, with closely cropped hair.

The other thing I wish I could tell everyone is that the machine learning is more specifically a parallel Bayesian inversion via MCMC (Metropolis modified with a form of "parallel tempering"), but that's trickier to explain so I'm worried folks are assuming we're using neural nets or something silly
