Crushed, Zapped, Boiled, Baked And More: Nature Used 57 Recipes To Create Earth’s 10,500+ “Mineral Kinds”

Malachite is an example of a mineral that formed after life created atmospheric oxygen about 2.5 billion years ago. They are among hundreds of beautiful blue and green copper minerals that form near Earth's surface as ore deposits weather. Credit: ARKENST

A 15-year study led by Carnegie’s Robert Hazen and Shaunna Morrison details the origins and diversity of every known mineral on Earth, a landmark body of work that will help reconstruct the history of life on our planet, guide the search for new minerals and ore deposits, predict possible characteristics of future life, and aid the search for habitable exoplanets and extraterrestrial life.

The Path To Pure Polynitrogen—New Compound A Crucial Step Toward Revolutionary Energy Storage

The path to pure polynitrogen—new compound a crucial step toward revolutionary energy storage

New work from an international team led by Carnegie’s Alexander Goncharov synthesized a new material composed of six nitrogen atoms in a ring, bringing scientists one step closer to creating a long-theorized, pure-nitrogen solid that could revolutionize energy storage and propulsion.

Direct images of young exoplanet points to controversial disk instability theory

Researchers directly imaged the newly forming exoplanet AB Aurigae b over a 13-year span using Hubble’s Space Telescope Imaging Spectrograph (STIS) and its Near Infrared Camera and Multi-Object Spectrograph (NICMOS).

A recent study published in Nature Astronomy may have revealed the first visual evidence confirming the formation of a gas giant planet via the controversial disk instability method, which was first proposed by Carnegie’s Alan Boss in 1997.

New work from a Smithsonian-led team, including Carnegie’s Diana Roman, revealed what could be the most-important factor controlling the depth at which magma is stored under a volcano, upending long-held theories about the molten material’s upward journey through the Earth’s crust. Their findings—which could inform the creation of detailed models that more accurately forecast volcanic eruptions—are published in Science.

Recently, a team of scientists led by Carnegie’s Samuel Dunning and Timothy Strobel developed an original technique that predicts and guides the ordered creation of strong, yet flexible, diamond nanothreads, surmounting several existing challenges.  The innovation will make it easier for scientists to predict and synthesize the nanothreads—an important step toward applying the material to practical problems in the future. The work was recently published in the Journal of the American Chemical Society.
