Antibiotic resistance may spread even more easily than expected

Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research at Chalmers University of Technology, Sweden, shows that one reason could be significant genetic ...

Gut microbiome manipulation could result from virus discovery

Scientists have discovered how a common virus in the human gut infects and takes over bacterial cells—a finding that could be used to control the composition of the gut microbiome, which is important for human health.

Mystery molecule in bacteria is revealed to be a guard

Peculiar hybrid structures called retrons that are half RNA, half single-strand DNA are found in many species of bacteria. Since their discovery around 35 years ago, researchers have learned how to use retrons for producing ...

Scientists engineer bacteria-killing molecules from wasp venom

A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has engineered powerful new antimicrobial molecules from toxic proteins found in wasp venom. The team hopes to develop the molecules ...
