The development of the Petri dish transitioned laboratory science from unpredictable liquid cultures to precise, observable experiments. This vessel remains a cornerstone of modern medical research and global food safety protocols.

Researchers reconstructed the evolutionary history of Acinetobacter baumannii by sequencing samples dating back to the 1970s. The study reveals how the bacterium evolved in waves to acquire resistance traits and survive medical interventions.

New research shows that human-associated bacteria can adapt to extreme Martian environments, posing significant health risks to astronauts and complicating planetary protection efforts.

New research indicates that Arctic soil microbes respond to thawing through staggered activation sequences and extensive genetic exchange. These biological dynamics significantly influence the decomposition of organic matter and greenhouse gas emissions.
