Antibiotic resistant prehistoric bacteria
Using a metagenomic approach, a canadian research group determined that antibiotic resistance genes are not an antibiotic-era evolutionary innovation, since beta-lactam, tetracycline and vancomycin resistance mechanisms can be tracked back to 30,000 year-old samples.
With the new European super-network of DNA databases, comprehensive DNA marker profiling is needed; otherwise, terrible mistakes will be made.
A synthetic genetic circuit that senses a cell’s microRNA profile can differentiate and induce apoptosis in cancerous cells, leaving healthy cells intact.
Calibration and oscillation’s characterization are essential for the development of a synthetic biological clock; researchers at the University of California are working with synthetic genetic circuits, microfluidics and developing mathematical models for the precise analysis and future application of these synthetic genetic circuits.
