Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by a vast ocean. Over the course of millions of years, in that primordial soup, life emerged.

Many scientists find it strange that every living thing on our planet forms its proteins from the exact same set of 20 amino acids. Why that specific set? Scientists know there are many more amino ...

With a newly developed method that compares AI-generated protein sequences with naturally occurring ones, function- and ...

Using quantum chemical methods, a team of researchers led by Dr. Matthias Granold and Professor Bernd Moosmann of the Institute of Pathobiochemistry at Johannes Gutenberg University Mainz solved one ...

A chemical conundrum complicates researchers’ understanding of how the first biological cells emerged. Those protocells were most likely formed from fatty acid vesicles serving as membranes. Some ...

Researchers at the Champalimaud Foundation discovered how fruit flies sense when they lack essential amino acids. Missing ...

Researchers from UNIGE and Marburg show that D-cysteine, the "mirror" form of cysteine, selectively targets certain cancer ...

New research from the Champalimaud Foundation (CF) reveals how missing just one essential amino acid can change gene expression and the brain's sensory systems, prompting animals to seek out ...

When a bone grows, our bodies’ proteins help provide the structure. When a muscle tears, proteins help rebuild it. When we fight an infection, transport oxygen in our blood or send messages to a cell, ...
