Did comet impacts jump-start life on Earth?

Comets screaming through the atmosphere of early Earth at tens of thousands of miles per hour likely contained measurable amounts of protein-forming amino acids. Upon impact, these amino acids self-assembled into significantly ...

Stop and go in the potassium channel

Cells need openings in the cell membrane in order to make exchanges with their environment. These openings are closable portals in which the signals are transported in the form of ions. Private lecturer Dr. Indra Schröder ...

Comet contains glycine, key part of recipe for life

An important amino acid called glycine has been detected in a comet for the first time, supporting the theory that these cosmic bodies delivered the ingredients for life on Earth, researchers said Friday.

Why is life left-handed? The answer is in the stars

While most humans are right-handed, our proteins are made up of lefty molecules. In the same way your left and right hands mirror one another, molecules can assemble in two reflected structures. Life prefers the left-handed ...

Amino acids key to new gold leaching process

Curtin University scientists have developed a gold and copper extraction process using an amino acid–hydrogen peroxide system, which could provide an environmentally friendly and cheaper alternative to conventional methods.

Fingerprint of dissolved glycine in the Terahertz range explained

Chemists at the Ruhr-Universität Bochum (RUB) have, for the first time, completely analysed the fingerprint region of the Terahertz spectrum of a biologically relevant molecule in water, in this case, an amino acid. By combining ...
