NewsSalmonella escapes host’s defences using two-pronged approach
Researchers have uncovered two strategies that the Salmonella enterica bacterium uses to protect itself from the human body’s defence mechanisms, both driven by the same protein.
-
NewsNanorobots seek and destroy fungal infections in the mouth
Researchers have developed a new way to rapidly and precisely eradicate fungal infections in the mouth by using nanorobots guided by magnets.
