It's life, but not as we know it. Researchers in the Netherlands have found that a microbe from deep beneath the ocean can breathe a major ingredient in rocket fuel. The discovery suggests that early life may have used many different kinds of chemicals besides oxygen to survive and thrive.
A team of American researchers is on a treasure hunt for jewels — of both artistic and historic value.
This month, researchers from Denver were in Russia to document the work of Vasily Konovalenko, a former ballet set designer turned sculptor, who created scenes from Russian folk life in semiprecious stones.
In the 1980s, Konovalenko emigrated from what was then the Soviet Union in search of artistic freedom. Now, his legacy is divided between the U.S. and Russia.
