Scientists from Auburn University have proposed a new mechanism to control some of the thinnest electronic memory devices ever made. Their study uncovers how tiny crystals only a few atoms thick may switch between insulating and metallic states, paving the way for low-power memory, flexible electronics, and brain-inspired computers.

While the early Mars climate remains an open question, a new study suggests its atmosphere may have been hospitable to life due to volcanic activity which emitted sulfur gases that contributed to a greenhouse warming effect.

The University of Pennsylvania's Bo Zhen and postdoctoral researcher Li He developed a system for guiding light through tiny crystals in ways that allow it to navigate undeterred by bumps and defects. Their work could lead to sturdier lasers, faster data links, and light-based chips that don’t get tripped up by imperfections.

LIGO's improved sensitivity is showcased in a discovery of a black hole merger detected in January of this year. Scientists analyzing this signal were able to provide the best observational evidence yet for what is known as the black hole area theorem, an idea put forth by Stephen Hawking in 1971 that says the total surface areas of black holes cannot decrease. 

When it comes to Earth’s climate system, water is often at the center of the story — whether it’s too much, too little or arriving at the wrong time. And while today’s climate models can tell us how much rain might fall or how humid the air might be, they often can’t answer the simpler, and perhaps more important, question: Where did this water come from? A new project led by Rice University and the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR) is changing that. Backed by a grant from the National Science Foundation, the initiative — called SCI-SWIM, short for sustainable community infrastructure for stable water isotope modeling — will build a new and improved version of the Community Earth System Model (CESM), which can trace water across the entire planet from the clouds in the sky to the thick ice sheets deep underground.
