Bacteria engage sulfur for plant salt tolerance

Understanding the interplay between bacteria and sulfur is leading to exciting biotechnologies that could enable crops to be irrigated with salty water.

Come on in, the water is superionic

The interiors of Uranus and Neptune each contain about 50 000 times the amount of water in Earth's oceans, and a form of water known as superionic water is believed to be stable at depths greater than about one-third of the ...

Enzyme action movie shows how nature makes penicillins

Scientists who specialize in studying the atom-by-atom choreography of enzymes have revealed new insights into the function of isopenicillin N synthase, an enzyme needed to produce some of the world's most critical antibiotics.

A major addition to chemists' toolkit for building new molecules

Chemists at Scripps Research have solved a long-standing problem in their field by developing a method for making a highly useful and previously very challenging type of modification to organic molecules. The breakthrough ...

How 'great' was the great oxygenation event?

Around 2.5 billion years ago, our planet experienced what was possibly the greatest change in its history: According to the geological record, molecular oxygen suddenly went from nonexistent to becoming freely available everywhere. ...

Hydrogen-producing enzyme protects itself against oxygen

An international research team from the Photobiotechnology Research Group at Ruhr-Universität Bochum (RUB) led by Professor Thomas Happe and the Laboratoire de Bioénergétique et Ingénierie des Protéines (CNRS) in Marseille ...

Lighting the path to recycling carbon dioxide

Semiconductive photocatalysts that efficiently absorb solar energy could reduce the energy required to drive a bioelectrochemical process that converts CO2 emissions into valuable chemicals, KAUST researchers have shown.

Water molecules are gold for nanocatalysis

Nanocatalysts made of gold nanoparticles dispersed on metal oxides are very promising for the industrial, selective oxidation of compounds, including alcohols, into valuable chemicals. They show high catalytic activity, particularly ...
