Battling persistence in tuberculosis bacteria

Researchers at the Indian Institute of Science (IISc), in collaboration with NCBS and InStem, have uncovered an important mechanism that allows the tuberculosis (TB) bacterium to persist in the human host for decades. They ...

Study finds corn genome can gang up on multiple pathogens at once

In a changing climate, corn growers must be ready for anything, including new and shifting disease dynamics. Because it's impossible to predict which damaging disease will pop up in a given year, corn with resistance to ...

Scientists discover small RNA that regulates bacterial infection

People with weakened immune systems are at constant risk of infection. Pseudomonas aeruginosa, a common environmental bacterium, can colonize different body parts, such as the lungs, leading to persistent, chronic infections ...

How male mosquitoes compensate for having only one X chromosome

The research group of Dr. Claudia Keller Valsecchi (Institute of Molecular Biology, Mainz, Germany) and their collaborators have discovered the master regulator responsible for balancing the expression of X chromosome genes ...

Yeast screen uncovers genes involved in chromosomal mutation

When creating a computer program, errors in the code can introduce bugs to the software. Similarly, errors in our body's genetic code, DNA, which is stored in structures known as chromosomes, can bring about mutations in ...

Copying nature to help plants resist viruses

For thousands of years, crops have been shaped by domestication processes. Farmers cross-breed and select new varieties, adapted to constantly changing environments. Although efficient, this process is time consuming. Moreover, ...
