Scientists at the Center for Molecular Medicine Cologne (CMMC) and the CECAD Cluster of Excellence on Aging Research have demonstrated in a biomedical study that ribosomes, the protein factories of our cells, face an unusually tough challenge when building large, membrane-embedded proteins. When protein synthesis fails, ribosomes recruit quality control factors to eliminate the resulting defective proteins.

Claim that science is becoming less disruptive challenged after years-long publication delay

A widely cited Nature cover article from 2023 claimed that scientific innovation has significantly declined in recent decades. This finding was based on a citation analysis of large sets of metadata concerning scientific papers and patents. Researchers from Vrije Universiteit Brussel (VUB) and KU Leuven have found that incomplete reference data account for most of the alleged decline in scientific disruption. Their article is also published in the journal Nature.

Microbes turn CO₂ into protein and vitamin B9 at commercially viable prices

Researchers are developing biotechnological processes that enable microbes to produce proteins and vitamins for human consumption using basic chemical ingredients, such as carbon dioxide, hydrogen and oxygen—entirely bypassing livestock farming and agriculture. Because these methods also require energy input, they are popularly called "power-to-protein" and "power-to-vitamin" processes.
