Biologists identify key step in lung cancer evolution

Biologists identify key step in lung cancer evolution

Blocking the transition to a more aggressive state could offer a new treatment strategy. Lung adenocarcinoma, an aggressive form of cancer that accounts for about...
Telomere length may predict cancer risk

Telomere length may predict cancer risk

Telomeres are regions of repetitive DNA at the end of human chromosomes, which protect the end of the chromosome from damage. Whilst shorter telomeres are...
CRISPR enzymes act like Pac-Man to chew up RNA

CRISPR enzymes act like Pac-Man to chew up RNA

Once activated, 10 newly described CRISPR enzymes behave like Pac-Man to run amok and destroy RNA. The findings could be useful for detecting infectious viruses. The...
Biology will take some mistakes to maintain speed

Biology will take some mistakes to maintain speed

When it comes to duplicating DNA, evolution seems to value speed over accuracy, new research suggests. The finding challenges assumptions that perfectly accurate transcription and...
