Carnegie-led team wins $1.5 million grant to study atmospheres of the galaxy’s most common exoplanets

Presentation Format AEThER.png

Carnegie’s Anat Shahar is the lead investigator on an interdisciplinary, multi-institution research team that this spring was awarded nearly $1.5 million from the Alfred P. Sloan Foundation to understand the chemical makeup of our galaxy’s most common planets with a goal of developing a framework for detecting chemical signatures of life on distant worlds.  


Where did Earth's water come from?

As a part of this month's geochemistry/cosmochemistry, Staff Scientist Conel Alexander explains where Earth's water comes from. 


New form of silicon could enable next-gen electronic and energy devices

Visualization of the structure of 4H-Si viewed perpendicular to the hexagonal axis. A transmission electron micrograph showing the stacking sequence is displayed in the background.

A team led by Carnegie’s Thomas Shiell and Timothy Strobel developed a new method for synthesizing a novel crystalline form of silicon with a hexagonal structure that could potentially be used to create next-generation electronic and energy devices with enhanced properties that exceed those of the “normal” cubic form of silicon used today.


Collaboration cracked the case on deep focus quakes

Blue Diamond Inclusion

When it comes to earthquakes, seismologists know best. But deep-focus earthquakes—those that occur between 300 and 700 km below the surface—have been a mystery to science for a century. Over the years, many scientists have suggested different answers to this problem. Still, the deep Earth is impossible to study directly, so the earthquakes kept their secrets until a group of scientists at the Earth and Planets Laboratory teamed up to crack the case. 


Carnegie’s Hazen honored for lifetime achievement in mineralogy

Robert Hazen DCO Portrait

Carnegie Mineralogist Robert Hazen—who advanced the concept that Earth’s geology was shaped by the rise and sustenance of life—will be honored with the 2022 the International Mineralogical Association’s Medal for Excellence. The prize recognizes “outstanding scientific publication in the field of mineralogical sciences.”


Postdoc Spotlight: Samuel Dunning searches for new materials under pressure

Samuel Dunning

Samuel (Sam) Dunning is a metal-organic framework (MOF) chemist who comes to us from the University of Texas Austin.  At EPL, Dunning is working with Staff Scientist, Tim Strobel to synthesize carbon nanothreads from small molecule compounds, with the specific aim of incorporating new functionalities and atoms into the threads at high pressure. His work will specifically focus on using molecular and non-molecular precursors for the high-pressure synthesis of extended solids.
