Bacteria

Under a DARPA contract, Raytheon is using synthetic biology techniques to produce two new strains of bacteria – one to seek out hidden explosives below ground and another on the surface that glows when they're found.

A new study is trying to answer a medical mystery - when does the microbiome begin to form? Is the womb and placenta a sterile environment, with bacteria seeded when a baby is born? Or can a mother transfer microbes to her child during pregnancy?

Researchers at Rice University have developed a new air filter made of graphene foam, which can kill captured microbes with small zaps of electricity.

Researchers have analyzed a weapon that bacteria use to kill each other – a toxic "crossbow bolt" – which could inspire new antibiotics.

For the first time, scientists in Australia have observed bacteria shedding their protective shells and changing shape to escape detection by antibiotics.

Scientists have found some of the earliest direct evidence of life, in the form of organic remains in 3.5-billion-year-old stromatolites in Australia.

A metastudy has affirmed the link between gum disease and hypertension, finding the worse a person’s oral health the greater their risk of suffering from high blood pressure.

A new study has discovered administering an antibiotic with a specific compound found in green tea can effectively kill a notoriously antibiotic resistant bacteria.

A new long-term study has found high levels of antibiotic-resistant bacteria in wild dolphins, with rates growing over the last decade.

Deadly, drug-resistant forms of K. pneumoniae bacteria are spreading. Thankfully a new vaccine has shown promise in tests on mice.

An intriguing study suggests beneficial blood pressure reductions following exercise are kickstarted by molecules released by bacteria in the mouth.

Researchers at Imperial College London have found that a high-priority superbug resists drugs by closing its pores.
