The Centers for Disease Control and Prevention (CDC) report that more than 2 million people in the United States become infected with an antibiotic-resistant strain of bacteria resulting in at least 23,000 deaths annually. Antibiotic resistance is of growing concern with the increase in resistant bacterial strains and the emergence of multi-drug resistant bacteria. The
New research from University of California, Santa Cruz reveals a repair mechanism that allows cells to rescue very damaged chromosomes during the cell division process. The study was published this June in the Journal of Cell Biology. Cells use a variety of checkpoints and safeguards to maintain chromosome integrity during cell growth and division. If
Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB), which remains one of the top ten causes of death worldwide, according to the World Health Organization (WHO). A recent study by investigators at Oregon State University identified mechanisms that the bacteria use to evade antibiotics and thus paves the way for new treatments for
In a study published in Nature Methods this spring, a team of researchers developed a way to use standard light microscopes to obtain very high-resolution pictures of tissue samples. The new method, termed iterative expansion microscopy, enables imaging at a resolution of 25 nanometers. Because it doesn’t require any specialized equipment, the new technique is
