Scientists simulate alien volcanoes here on Earth
A small volume of liquid iron snakes across the top of the molten rock as narrow rivers flowing ten times faster than that underlying lava. Despite initially being a whopping 2,200 degrees Fahrenheit, these rivers rapidly cool and solidify before the snail-like shimmying of the ropey lava below snaps them into pieces. Most of the liquid iron, though, sinks into the lava. It bunches up toward the front of the lava flow before exploding out of it as braided, winding streams — silvery strokes of an altogether alien calligrapher. Dr. Brandon Johnson of Purdue EAPS is cited in this article by Supercluster.

Programs prepare faculty to lead; 20 participants selected for 2021-22 academic year
The Provost’s Office has named the 20 faculty members who will participate in the Big Ten Academic Alliance Academic Leadership Program and the Purdue Insights Forum programs in the 2021-22 academic year. The Big Ten Academic Alliance Academic Leadership Program and the Purdue Insights Forum are designed to help faculty interested in taking on administrative and leadership roles, although each program takes a distinct approach to achieving the goal. Dr. Lisa Welp, EAPS associate professor, has been selected as a 2021-22 Purdue Insights Forum Program Fellows.

Geochemist Marissa Tremblay’s Noble and Versatile Toolbox
AAAS Spotlight: Don’t underestimate the value of a spring break field trip. For noble gas geochemist Marissa Tremblay, a geology field trip to Death Valley when she was a freshman at Barnard College set her scientific career in motion. While other students slept in the van on the long drives through the desert, she sat up front asking her professor questions, mesmerized by geological time scales.

What a Lake in Turkey Can Tell Us about Mars
On February 18, 2021, the Perseverance rover is scheduled to make a historic landing in Jezero Crater on Mars. The rover will survey the area and collect rock samples to send back to Earth. Even though no human has set foot inside the crater, researchers have some ideas of what to expect thanks to a similar landscape on Earth: Lake Salda.

'Leaky' noble gas behavior could provide missing link in predicting climate change
An early-career scientist, Marissa Tremblay, professor of geochemistry, has developed a novel method of measuring the temperature history of continental surfaces, a critical innovation considering that most information on past climate comes from ocean data. As overall global temperatures in 2020 reached record highs, data collected through this new method could help scientists working diligently to discover innovative ways of understanding and addressing climate change. Tremblay also received the 2021 Marion Milligan Mason Award for Women in the Chemical Sciences from the American Association for the Advancement of Science.
