When agricultural weeds evolve resistance to herbicides, they do it in one of two ways. In target-site resistance, a tiny mutation in the plant's genetic code means the chemical no longer fits in the protein it's designed ...

A team of researchers working at the Francis Crick Institute has developed a way to find mutations in similar genome regions of cancer samples. In their paper published in the journal Nature Biotechnology, the group describes ...
Proteins known as transcription factors act as switches that regulate the expression of nearby genes, but the identity of some of these genetic levers has so far remained mysterious. Now, researchers from the Schübeler group ...
