It has been proposed that spin-polarized cosmic radiation can induce asymmetric changes in helical biopolymers that may account for the emergence of biological homochirality. The parity violation in the weak interaction has direct consequences on the transport of polarization in cosmic ray showers.

Phosphorus is an element essential for life. It is fundamental to all living organisms, and is a key component of RNA, DNA, and cell membranes.

Scientists frequently look at how molecules behave in nature to help them design chemical processes, and that's what Queensland University of Technology (QUT) and Ghent University researchers did to create a green light-stabilised 3D polymer structure that unfolds itself when left in darkness.

"I'm fascinated with life, and that's why I want to break it." This is how Betül Kaçar, an assistant professor at the University of Arizona with appointments in the Department of Molecular and Cellular Biology, Department of Astronomy and the Lunar and Planetary Laboratory, describes her research.

A research team at Uppsala University has resurrected several billion-year-old enzymes and reprogrammed them to catalyse completely different chemical reactions than their modern versions can manage.

The nitrogenase metalloenzyme family, essential for supplying fixed nitrogen to the biosphere, is one of life's key biogeochemical innovations.

New research on an enzyme that is essential for photosynthesis and all life on earth has uncovered a key finding in its structure which reveals how light can interact with matter to make an essential pigment for life.

The enzyme-nitrogenase-can be traced back to the universal common ancestor of all cells more than four billion years ago.

Earth didn't always harbor life. But around 4 billion years ago, something in the environment changed, and systems with biological properties began to emerge.

The Origins Of Metabolism

Sheding light on one of the most enduring mysteries of science: How did metabolism - the process by which life powers itself by converting energy from food into movement and growth - begin?
