Researchers test quantum encryption hacking risk

(Phys.org) —Quantum communication systems offer the promise of virtually unbreakable encryption. Unlike classical encryption, which is used to send secure data over networks today and whose security depends on the difficulty ...

Some bacteria attack using spring-loaded poison daggers

Bacteria have evolved different systems for secreting proteins into the fluid around them or into other cells. Some, for example, have syringe-like exterior structures that can pierce other cells and inject proteins. Another ...

Decoding the molecular machine behind E. coli and cholera

Scientists from Queen Mary, University of London have discovered the workings behind some of the bacteria that kill hundreds of thousands every year, possibly paving the way for new antibiotics that could treat infections ...

Study shows how Salmonella survives in environment

Scientists at the University of Liverpool have demonstrated how a single-celled organism, living freely in the environment, could be a source of Salmonella transmission to animals and humans.

The importance of vaccinations for cats

Kittens and cats, whether they live indoors or outdoors, can be exposed to diseases caused by viruses or bacteria. Vaccinations help protect our feline friends by preventing the spread of these diseases and boosting their ...

Researchers show how opportunistic bacterium defeats competitors

Researchers at the University of São Paulo (USP) in Brazil have described a system present in a species of opportunistic bacterium found in hospital environments that injects a cocktail of toxins into competing bacteria ...
