New Synthesis Technique Leads to Over 300 Candidate Antibiotics

The combination of drug misuse, reductions in antimicrobial research by the pharmaceutical industry, and the rapid evolution capabilities of microorganisms has resulted in pathogenic bacteria with stronger and stronger drug resistance. This is an issue that some fear if not handled correctly, could lead to the evolution of a “superbug” that is resistant to everything in our arsenal.

New Cpf1 Molecular Scissors to Take Genomic Editing to the Next Level

CRISPR (Clustered Regularly Interspaced Palindromic Repeats) gene editing technology allows permanent modification of genes within organisms. It is considered a breakthrough in biotechnology ever since its discovery.  Researchers from the University of Copenhagen (Denmark), led by Spanish researcher Guillermo Montoya, now went one step further. They discovered how Cpf1, a new type of molecular scissors, unzip and cleave DNA.

Evolution in Action

Scientists from Harvard Medical School and Technion-Israel Institute of Technology have ingeniously visualized the Escherichia coli evolution through ever increasing amounts of antibiotics. Inspired by a Hollywood movie billboard, the team constructed the so called Microbial Evolution and Growth Arena i.e. MEGA plate to be able to monitor bacteria’s movement, survival and resistance.
