The Genetic Mechanics of Bacterial Circadian Clocks

Circadian clocks play an important role in our health and well-being by synchronizing the 24-hour biological cycles with light and dark exposure. Disruptions in the rhythms of these clocks, such as jet lag and daylight saving time, might put their everyday operations out of sync.

New Research Reveals RFC's Dynamic Partnership in DNA Synthesis

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its code and build new strands.

Scientists Identify TRPM4 as Key Molecular Switch Controlling Intestinal Fluid Balance

Although constipation and diarrhea may seem like opposite problems, they both hinge on the same underlying issue: how much fluid moves into the gut. These common issues affect millions of people in the U.S. each year, yet scientists have not fully understood what regulates intestinal fluid balance.

Unusual Antibody Tactics Hinder Pathogen Attachment to Cells

Pathogens can create sticky situations. When microbes invade the body to cause an infection, often one of their first lines of attack is to cling tenaciously to the surfaces of targeted human cells.
