Cover crops show the clearest gains in soil health across US long-term trials, study shows
Farmers have long debated which practices do the most to keep their soil healthy. Now, after pulling data from 21 long-term field trials scattered across the United States, a multi-state research team has found cover crop use comes on top.

Cells under stress: How a chemotherapy drug damages RNA
The integrity of DNA and RNA is essential for every cell. DNA contains the genetic information for proteins, while RNA serves as a working copy of individual genes and is required for the synthesis of proteins. Unlike DNA mutations, RNA damage is…

Cornerstone model of evolutionary biology built on math flaw, study argues
New research is significantly revising a widely cited evolutionary model, the Inhibitory Cascade Mode (ICM). Benjamin Auerbach, professor in the Department of Ecology and Evolutionary Biology at the University of Tennessee, Knoxville, and Charles…

Why cells stick differently: New clues could inform skin and inflammatory disease research
Scientists led by Sergey Troyanovsky, Ph.D., professor of Dermatology and of Cell and Developmental Biology, have uncovered new intracellular mechanisms promoting cell-cell adhesion, a process disrupted in a variety of skin and inflammatory…

Two organs, one brain area: How fish orient themselves in the water
Using zebrafish, researchers from Osaka Metropolitan University (OMU) have identified the tegmentum region in the fish midbrain as the area where light input from both the fish’s eyes and the pineal organ—the “third eye”—is integrated. Their…

Wildlife-friendly landscapes dramatically boost biodiversity in fragmented forests, research reveals
A new study has revealed that improving the landscapes surrounding forest remnants can dramatically increase their ability to retain bird species—even when the forest fragments themselves are small or isolated. For decades, traditional…

Limits of protein evolution could reshape ideas about early life
The number of known proteins is infinitely small in comparison to the universe of possible proteins, which could in theory be realized. Yet these known proteins are the only major training ground for future protein design. Understanding how…

Soil bacteria break down toxic chemicals in the environment
Many aromatic compounds, such as phenols, cresols and styrenes, are toxic to organisms and harmful to the environment. They can accumulate as a result of industrial processes and harm ecosystems. Soil bacteria can help to break them down.
