In our new paper, we revisited 51 forest metatranscriptomes from 4 European and North American forest regions - and found that protistan predators outshine fungi in activity!

`Through genome-wide CRISPR screening, we identified the RNA-binding protein DHX29 as a critical regulator of codon-dependent gene expression. Cryogenic electron microscopy and selective ribosome profiling demonstrated that DHX29 directly interacts with the A-site entrance of the translating 80S […]

Complex Life Started Nearly a Billion Years Earlier Than We Thought New research indicates that complex life began forming almost a billion years earlier than previously thought. Using an expanded molecular clock approach, scientists mapped out a clearer timeline of how early gene families evolved. They discovered that key eukaryotic features emerged long before mitochondria or atmospheric oxygen became abundant. The result is a new evolutionary [...]
