NewsGenes from corn’s wild ancestor change soil microbial community, improve sustainability
Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction, according to new research. It’s the first time corn’s genetic makeup has been linked with inhibition of nitrifying and denitrifying bacteria.

NewsNot the usual suspects: Novel genetic basis of pest resistance to biotech crops
A study reveals a novel genetic basis of resistance to transgenic crops in the corn earworm. To gain protection from this pest, crop plants had been genetically engineered to produce proteins from the common bacterium Bacillus thuringiensis, or Bt.

NewsLoss of ‘nitrogen fixers’ threatens biodiversity and ecosystems
A new study reveals that increased nitrogen deposition from human activity is reducing the diversity and evolutionary distinctiveness of nitrogen-fixing plants, leading to simplified plant communities with fewer species of nitrogen fixers.

NewsNew study highlights scale and impact of long COVID
A wide range of biological mechanisms are involved in long Covid, including persistence of the original virus in the body, disruption of the normal immune response, and microscopic blood clotting, even in some people who had only mild initial infections.
