Researchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step toward the construction of a programmable genetic sensor. The scientists recently synchronized these bacterial “genetic clocks” to blink in unison and engineered the bacterial genes [...]

German scientists develop fast-acting germ killer
Posted by Siril on January 20th, 2010
A new fast-acting disinfectant that is effective against bacteria, viruses and other germs could help stop the spread of deadly infections in hospitals, German scientists said on Wednesday. Researchers from the Robert Koch Institute in Berlin said they had developed a fast-acting, practical formula which would kill germs on surgical instruments without damaging them through [...]
Single Atom Controls Motility Required for Bacterial Infection
Posted by mrudula on January 11th, 2010
Bacteria can swim, propelling themselves through fluids using a whip-like extension called a flaggella. They can also walk, strolling along solid surfaces using little fibrous legs called pili. It is this motility that enable some pathogenic bacteria to establish the infections such as meningitis that cause their human hosts to get sick or even die. [...]
