We know the menagerie of microbes in the gut has powerful effects on our health. Could some of these same bacteria be making a home in our brains?
Bacteria living 4000m below the ocean surface in the Clarion-Clipperton Fracture Zone (CCFZ) are consuming carbon dioxide and turning it into biomass, a new study shows.
Don’t worry, no one has gotten sick yet.
The most economical way to kill bacteria that cause common food-borne illnesses—mostly caused by Salmonella enterica—is heat, but, the mechanisms that kill Salmonella at lower temperatures were not fully understood until now, according to a team of researchers.
The appearance of a botulinum-like toxin in Enterococcus — a ubiquitous bacterium and an emerging cause of multidrug-resistant infections — is raising scientific concern.
New technology may one day allow doctors to image therapeutic bacterial cells in patients
At the University Sapienza in Rome, a team of researchers from the Physics Department and the Institute for Nanotechnology of the CNR, lead by physics professor Roberto Di Leonardo, has shown that genetically modified bacteria, expressing the protein proteorhodhopsin, can be used as tiny propellers in micromachines that are invisible to the human eye and whose speed can be reliably and continuously tuned by shining green light of controlled intensity.
Somewhere between Earth’s creation and where we are today, scientists have demonstrated that some early life forms existed just fine without any oxygen. While researchers proclaim the first half of our 4.5 billion-year-old planet’s life as an important time for the development and evolution of early bacteria, evidence for these life forms remains sparse including
Geneticists have made a step forward in ‘recoding’ the genome as we know it, replacing 62,214 DNA base pairs in a synthetic E. coli genome.
