New tests could verify general theory of relativity, or find flaws
Through dust, not rust, the metal plays a complex, controversial role in Earth’s climate
Compounds with noble gases don’t form naturally on Earth. But in the interstellar medium, they are helping scientists probe the history of the universe.
Scientists track gas through time and space to better understand how conglomerations of stars are born and die

To slow or stop global warming, the world agrees it must cut carbon dioxide emissions. But monitoring each nation’s output of greenhouse gases is not always straightforward.
Move over, flat carbon. Meet borophene, phosphorene and the rest of the next generation of “atomically thin” super-materials.
VIDEO: Megafires, which burn over 100,000 acres, can cause catastrophic damage. Researchers are studying fire behavior in the lab and in the field in order to fight these flames more effectively.
People have been using metals to manipulate light for centuries. Now researchers are using it to create powerful biosensors.

VIDEO: Our galaxy may seem humble, but here are a few things to know about what makes it an exceptional place
Hot Jupiters were the first kind of exoplanet found. A quarter-century later, they still perplex and captivate — and their origins hold lessons about planet formation in general.
Several new missions aim squarely at a long-standing astronomical conundrum, with the promise of improving space-weather predictions
Of the millions of substances people encounter daily, health researchers have focused on only a few hundred. Those in the emerging field of exposomics want to change that.
Lunar samples hinted at a barrage of debris pummelling planets billions of years ago. Fifty years after Apollo 11, that story is still unfolding.
Our galaxy is far bigger, brighter and more massive than most others
To understand what might be lost, ecologist Janet K. Jansson taps molecular methods to explore Earth’s underground microbes, from the permafrost to the grasslands
Physicists find hints that entanglement explains Einstein’s equations for gravity
Ancient rocks suggest that ice entirely covered our planet on at least two occasions. This theory may help explain the rise of complex life that followed.
Researchers probe the weather-like physics of deadly infernos
After 100 years as a national park and eons as a geological wonder, the American icon continues to reveal layers of its past and of the landscape ahead
