Life on Earth has a peculiar property – many biological molecules have a handedness, or a “chirality.” DNA twists one way and not the other, and all the rest of life must fit to this reality. In a new paper, researchers say they know why: It all comes down to physics! The answer could change our understanding of life across the universe. Let’s take a look.

How does nature build one of the most sophisticated catalytic metal centers found in biology? An international team of researchers has now resolved a long-standing debate surrounding the assembly of the active site of [FeFe]-hydrogenases—enzymes that rank among nature's most efficient catalysts for hydrogen production and consumption.

Nylon is a representative plastic material used throughout our daily lives, from clothing to automobiles. However, most of its raw materials have been produced through petrochemical processes, resulting in large carbon emissions. KAIST researchers have developed a technology that can produce key nylon precursors in an eco-friendly way using microbes.

The latest production from the "molecular movie" imaging technology developed at Oregon State University is a new, inexpensive way of dealing with a common environmental pollutant. Based on short-pulse lasers, the imaging technology allows chemical and biological actions to be measured as they are occurring, one high-speed frame at a time.
