Resistant Bacteria Protect The Colony
In the war against antibiotics, bacteria aren't selfish. According to a new report from Howard Hughes Medical Institute (HHMI) researchers, a handful of resistant pathogens can protect an entire colony. Prevailing wisdom held that antibiotic resistance works only on an individual level: a bacterium acquires a genetic mutation that confers protection against a drug, allowing it to survive and reproduce. Eventually, as vulnerable bacteria die, the mutant's stronger progeny repopulate the colony... (Source: Health News from Medical News Today)
Immune System Finding May Lead To New Ways To Detect, Diagnose And Treat Cancer And Other Diseases
When it comes to the mechanics of the human immune system, we are all more alike than previously thought, according to a new study by scientists at Fred Hutchinson Cancer Research Center. This finding has significant implications for developing new ways to detect, diagnose and treat cancer and diseases of the immune system, according to Harlan Robins, Ph.D., corresponding author of a paper detailing the research in Science Translational Medicine...
