Read moreSites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. The finding suggests that the delay itself may be the key that allows the protein molecule to find its target, according to the researchers.

Read moreCurrently, doctors have to throw away more than 80 percent of donated tissue used for joint replacements because the tissue does not survive long enough to be transplanted. Now, researchers have developed a new technology that more than doubles the life of the tissue. This new technology was able to preserve tissue quality at the required level in all of the donated tissues studied, the researchers found.

Read moreA new study shows that UV treatment alone can push bacteria into a dormant state instead of killing them, and that in some cases, the bacteria can later revive and proliferate.

Read moreThese new DNA probes can potentially be used to develop a biosensor array for lanthanide and other metal detection. These DNA molecules have catalytic activity (known as DNAzymes) and studies indicate that lanthanide-dependent DNAzymes may have different properties from existing examples.

Read moreScientists have shed light on how naturally occurring mutations can be introduced into our DNA. The study, which focuses on how DNA replicates every time a cell divides, helps to make clear previously unexplained patterns in how our DNA changes over time. It also provides new insight into how the human genome has been shaped throughout evolution.

Read moreDefective cilia can lead to a host of diseases and conditions in the human body - from rare, inherited bone malformations to blindness, male infertility, kidney disease and obesity. A new study from University of Georgia cellular biologists shows the mechanism behind tubulin transport and its assembly into cilia, including the first video imagery of the process.

Read moreTo survive and fulfill their biological functions, cells need to take in material from their environment. In this process, proteins within the cell pull inward on its membrane, forming a pit that eventually encapsulates the material in a bubble called a vesicle. Researchers have now revealed a relationship that governs this process, known as endocytosis.

Read moreA new computational approach allows to account for confounding factors and hidden biological processes in the analysis of single-cell RNA sequence data. Using this method, individual subpopulations and cell types can be identified within heterogeneous cell populations and can be determined more precisely.
