Discovering H2O2 sensing capacity in plants that control immunity

All aerobic organisms produce the molecule hydrogen peroxide (H2O2). When present in low concentrations, it acts as a crucial secondary signal to control a variety of biological processes, including but not limited to plant-microbe interactions, abiotic stress tolerance, pollen tube growth, root hair formation, leaf cell expansion, and Casparian strip formation.

Dual threat may lead cyanobacteria to take in more carbon

The types of ocean bacteria known to absorb carbon dioxide from the air require more energy – in the form of carbon – and other resources when they're simultaneously infected by viruses and face attack from nearby predators, new research has found.

Rising winter temperatures and rainfall pose a significant new threat to U.S. water quality

Scientists are ringing alarm bells about a significant new threat to U.S. water quality: as winters warm due to climate change, they are unleashing large amounts of nutrient pollution into lakes, rivers, and streams.

New insight into human genome evolution

Researchers discovered that in one out of every 4,000 births, some of the genetic code from the mitochondria—the “batteries” that power human cells—inserts itself into the DNA, giving a startling new insight into how humans evolve.
