Study Reveals Hidden Function of So-Called Junk DNA

A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic "junk", may actually play powerful roles in regulating gene expression.

Simple Models Reveal Soil’s Complex Microbial Conversations

Just like any living organism, the soil has its own metabolism. Plants, worms, insects, and most importantly, microorganisms in the soil, break down organic matter, consume and generate nutrients, and process other materials to give the soil a life of its own.

Paternal miRNAs Play Unexpected Role in Seed Viability and Embryogenesis

By using targeted gene silencing in different pollen cell types, the study reveals that disrupting DCL1 function either in the vegetative cell or in sperm cells leads to defective seed formation.

Scientists Uncover How New Genes Are Switched On in Fruit Flies

Most genes are ancient and shared across species. But a small subset of genes are relative newcomers, spontaneously emerging from stretches of DNA that once encoded nothing at all.

LINE1 Retrotransposon Found to Exploit Dormant Protein in Human Cells

An international research team led by Freiburg biologists Dr. Wenjing Qi and Prof. Ralf Baumeister has discovered how the LINE1 retrotransposon exploits a cell protein to become active itself, as occurs in tumors.

Cryo-EM Uncovers How Tiny Protein Enzyme Precisely Trims tRNA

To build proteins, cells rely on a molecule called transfer RNA, or tRNA. tRNAs act like protein-building couriers, where they read the genetic instructions from messenger RNA, mRNA, and deliver the right amino acids to ribosomes, the cell's protein-making factories.
