New work upends understanding of how blood is formed

The origins of our blood may not be quite what we thought. Using cellular "barcoding" in mice, a groundbreaking study finds that blood cells originate not from one type of mother cell, but two, with potential implications ...

HIV virulence depends on where virus inserts itself in host DNA

The human immunodeficiency virus (HIV) can insert itself at different locations in the DNA of its human host - and this specific integration site determines how quickly the disease progresses, report researchers at KU Leuven's ...

Scientists call for caution in using DNA-editing technology

A group of 18 scientists and ethicists today warned that a revolutionary new tool to cut and splice DNA should be used cautiously when attempting to fix human genetic disease, and strongly discouraged any attempts at making ...

Scientists measure energy released from a virus during infection

Within a virus's tiny exterior is a store of energy waiting to be unleashed. When the virus encounters a host cell, this pent-up energy is released, propelling the viral DNA into the cell and turning it into a virus factory. ...

Simulations show how to make gene therapy more effective

Diseases with a genetic cause could, in theory, be treated by supplying a correct version of the faulty gene. However, in practice, delivering new genetic material to human cells is difficult. A promising method for the delivery ...
