While titanium implants such as artificial hips can greatly improve patients' lives, they're also subject to serious bacterial infections. An experimental new antibacterial titanium alloy, however, could make such problems a thing of the past.Continue ReadingCategory: Medical, ScienceTags: Washington State University, Implant, Titanium, Alloy, Antibacterial
For the first time, researchers have found a bacterium that forms superstructures when it gets caught in sticky traps made by other bacteria, helping it erode enamel and form cavities. The finding could lead to new ways to keep our teeth clear of the invaders.Continue ReadingCategory: Medical, ScienceTags: Cavity, Dental, Biofilm, Microbes, Bacteria, University of Pennsylvania, Teeth
Scientists have reconstructed the genomes of microbes from the Stone Age, and used them to produce new molecules. The complex puzzle was pieced together from DNA fragments of bacteria on the teeth of ancient humans and Neanderthals.Continue ReadingCategory: Biology, ScienceTags: Bacteria, Genome, DNA, Enzyme, Fossils, Harvard, Max Planck Institute
Engineers at EPFL have found a way to insert carbon nanotubes into photosynthetic bacteria, which greatly improves their electrical output. They even pass these nanotubes down to their offspring when they divide, through what the team calls “inherited nanobionics.”Continue ReadingCategory: Energy, ScienceTags: Bacteria, Solar Cell, Photovoltaic, EPFL, Carbon, Nanotubes
Diversifying our energy sources is a key part of reducing our reliance on fossil fuels, and one intriguing possibility is to tap into electricity-producing bacteria. Engineers at Binghamton University have now developed a biobattery that contains three layers of different bacteria species, which together take in sunlight and produce electricity.Continue ReadingCategory: Energy, ScienceTags: Bacte is a social bookmarking place where you can share, find & discuss the best news around on most topics.
