How equal charges in enzymes control biochemical reactions

It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes—the biological catalysts in all living organisms—form ...

Changing the handedness of molecules

Researchers at Kanazawa University report in Proceedings of the National Academy of Sciences a responsive molecular system that, through chemical reactions, inverses its chirality before becoming racemic.

Molecule snapshot by explosion

Exploding a photo subject in order to take its picture? An international research team at the European XFEL, the world's largest X-ray laser, applied this "extreme" method to take pictures of complex molecules. The scientists ...

The pathway for producing ethylene

New research lays out the chemical steps used by a naturally occurring enzyme to convert a common chemical compound into ethylene—a plant hormone important for fruit ripening and an industrial chemical used in the production ...

The birth of a subnanometer-sized soccer ball

Ever since the existence of molecules was proven and molecular reactions were predicted, humans have wanted to visually observe how such events proceed. Such observations of single-molecule reactions are highly important ...

Lab one step closer to understanding how life started on Earth

How did life begin on Earth and could it exist elsewhere? Researchers at Simon Fraser University have isolated a genetic clue—an enzyme known as an RNA polymerase—that provides new insights about the origins of life. ...

Research uncovers missing physics in explosive hotspots

Research conducted on Lawrence Livermore National Laboratory's (LLNL) supercomputer Quartz highlights findings made by scientists that reveal a missing aspect of the physics of hotspots in TATB (1,3,5-trimamino-2,4,6-trinitrobenzene) ...

Extreme UV laser shows generation of atmospheric pollutant

An advanced laser technique has allowed researchers to observe, in real-time, the decomposition of a pollutant into atmospheric nitrous acid, which plays a key role in the formation of ozone and photochemical smog. The technique, ...
