Bacteria modify their ribosomes when exposed to widely used antibiotics, according to research published today in Nature Communications. The subtle changes might be enough to alter the binding site of drug targets and constitute a possible new mechanism of antibiotic resistance. Escherichia coli is a common bacterium which is often…

A new study from the Centre for Genomic Regulation (CRG) in Barcelona reveals that bacteria can modify their ribosomes when exposed to commonly used antibiotics, potentially contributing to antibiotic resistance. These subtle changes could alter the drug-binding sites on ribosomes, making antibiotics less effective. The study focused on *Escherichia coli*…

The discovery of antibiotics is one of the greatest medical breakthroughs of the 20th century. Before antibiotics, childbirth, a urinary tract infection, or a simple cut could lead to death from infection. Antibiotics, a type of antimicrobial, have made many modern medical procedures possible, and now the global healthcare system…

When people ask me how to separate AI hype from reality in medicine, I suggest starting with three ... critical questions. getty Artificial intelligence has long been heralded as a transformative force in medicine. Yet, until recently, its potential has remained largely unfulfilled. Artificial intelligence has long been heralded as…
