CRISPR enzyme programmed to kill viruses in human cells
Researchers have now turned a CRISPR RNA-cutting enzyme into an antiviral that can be programmed to detect and destroy RNA-based viruses in human cells.

Scientists are decoding the genetic mechanisms of aging
Scientists describes the mechanisms by which longevity is regulated post-transcriptionally, or after a genetic blueprint has been transcribed from an organism's DNA. The identification of these mechanisms will serve as a road map for screening new, more specific drugs to prolong healthy lifespan. The laboratory focuses on research on regeneration and aging.

Molecular biologists have pinpointed a gene that allows chlamydia to take up DNA from its host environment.
Read moreKoala epidemic provides lesson in how DNA protects itself from viruses
In animals, infections are fought by the immune system. Studies on an unusual virus infecting wild koalas, by a team of researchers reveal a new form of "genome immunity."
Read moreHumans have salamander-like ability to regrow cartilage in joints
Contrary to popular belief, cartilage in human joints can repair itself through a process similar to that used by creatures such as salamanders and zebrafish to regenerate limbs, researchers found.
Read moreDNA study sheds new light on the people of the Neolithic battle axe culture
Scientists have combined archaeological, genetic and stable isotope data to understand the demographic processes associated with the iconic Battle Axe Culture and its introduction in Scandinavia.
Read moreResearchers use game theory to successfully identify bacterial antibiotic resistance
Researchers have developed a novel way to identify previously unrecognized antibiotic-resistance genes in bacteria.
Read moreFruit flies help in the development of personalized medicine
It is common knowledge that there is a connection between our genes and the risk of developing certain diseases. In a study on fruit flies, researchers have found that gene mapping can also be used to predict response to a given treatment. This knowledge is crucial for the development of personalized medicine.
Read moreDNA metabarcoding useful for analyzing human diet
A new study demonstrates that DNA metabarcoding provides a promising new method for tracking human plant intake, suggesting that similar approaches could be used to characterize the animal and fungal components of human diets. The study demonstrated that dietary plant DNA can be amplified and sequenced from human stool using methods commonly applied to wildlife studies.
Read moreLimitations of method for determining protein structure
A new study by chemists shows that X-ray crystallography, the standard method for determining the structure of proteins, can provide inaccurate information about membrane proteins, which in turn could lead to poor and inefficient drug design.
