Dental plaque DNA shows Neandertals used 'aspirin'

Ancient DNA found in the dental plaque of Neandertals - our nearest extinct relative - has provided remarkable new insights into their behaviour, diet and evolutionary history, including their use of plant-based medicine ...

Highly organized structures discovered in microbial communities

Bacteria usually live in mixed communities with many different kinds of bacteria present. But it's been largely unknown how these communities are organized, because the technology didn't exist to see how they are structured ...

Nanoparticles release drugs to reduce tooth decay

Therapeutic agents intended to reduce dental plaque and prevent tooth decay are often removed by saliva and the act of swallowing before they can take effect. But a team of researchers has developed a way to keep the drugs ...

Study reveals secrets of bacterial slime

(Phys.org) —Newcastle University scientists have revealed the mechanism that causes a slime to form, making bacteria hard to shift and resistant to antibiotics.

Ancient teeth bacteria record disease evolution

DNA preserved in calcified bacteria on the teeth of ancient human skeletons has shed light on the health consequences of the evolving diet and behaviour from the Stone Age to the modern day.
