Hidden symmetry found in chemical kinetic equations

Rice University researchers have discovered a hidden symmetry in the chemical kinetic equations scientists have long used to model and study many of the chemical processes essential for life.

Researchers develop an artificial chloroplast

Over billions of years, microorganisms and plants evolved the remarkable process we know as photosynthesis. Photosynthesis converts sun energy into chemical energy, thus providing all life on Earth with food and oxygen. The ...

Technique could enable cheaper fertilizer production

Most of the world's fertilizer is produced in large manufacturing plants, which require huge amounts of energy to generate the high temperatures and pressures needed to combine nitrogen and hydrogen into ammonia.

Peptides that can be taken as a pill

Peptides are short chains of amino acids that occur in our body, in plants or bacteria to control diverse functions. Several peptides are used as drugs such as insulin, which controls the metabolism of sugar; and cyclosporine, ...

Untangling a key step in photosynthetic oxygen production

Photosystem II is a protein complex in plants, algae and cyanobacteria that is responsible for splitting water and producing the oxygen we breathe. Over the past few years, an international collaboration between scientists ...
