Microbiology


North Carolina State University researchers have developed a technique to selectively kill specific strains of bacteria.
Researchers from North Carolina State University have developed a de facto antibiotic "smart bomb" that can identify specific strains of bacteria and sever their DNA, eliminating the infection. The technique offers a potential approach to treat infections by multi-drug resistant bacteria.

Biotechnology


Researchers achieved precise gene modification in monkeys.
Monkeys are important for modeling diseases because of their close similarities to humans, but past efforts to precisely modify genes in primates have failed. In a study published by Cell Press January 30th in the journal Cell, researchers achieved precise gene modification in monkeys for the first time using an efficient and reliable approach known as the CRISPR/Cas9 system. The study opens promising new avenues for the development of more effective treatments for a range of human diseases.

AIDS & HIV

The human intestinal tract, or gut, is best known for its role in digestion. But this collection of organs also plays a prominent role in the immune system. In fact, it is one of the first parts of the body that is attacked in the early stages of an HIV infection. Knowing how the virus infects cells and accumulates in this area is critical to developing new therapies for the over 33 million people worldwide living with HIV. Researchers at the California Institute of Technology (Caltech) are the first to have utilized high-resolution electron microscopy to look at HIV infection within the actual tissue of an infected organism, providing perhaps the most detailed characterization yet of HIV infection in the gut.
