Brute force in the clinic

Article Abstract:

Researchers are using brute-force 'metagenomic' studies in which they extract microbial DNA from the body cavity of choice and test it on a sequencing machine. Clinical microbiologists on the other hand are still using traditional methods of identifying infectious microbes by growing it on certain agar media or examining the shape of fungi's tentacles under the microscope. Hence it is suggested that with an increase in funding, microbiologists can be trained to trial new diagnostic methods.

The heart of the cycle

Article Abstract:

The study provides a glimpse into how cells ensure the proper timing of completion of the cycle of DNA is presented. The cell-division machinery contains a self-perpetuating engine whose mechanism is based on alternating two intertwined enzymatic activities, namely enzymes that add phosphate groups to other proteins, and enzymes that guide periodic protein destruction.
