Researchers designed a powerful bacterial sensor with a stable gene circuit in a colonizing bacterial strain that can record gut inflammation for six months in mice. This study offers a solution to previous challenges associated with living diagnostics and may bring them closer to use in human patients.
An experimental treatment in mice allows the reprogramming of blood cells in order to promote the healing process of cutaneous wounds. This approach could prove to be beneficial in healing challenging wounds in diabetics and major-burn victims.
Scientists have created artificial viruses that can be used to target cancer. These designer viruses alert the immune system and cause it to send killer cells to help fight the tumor. The results provide a basis for innovative cancer treatments.
Researchers have managed to synthesise lung surfactant, a drug used in the care of preterm babies, by mimicking the production of spider silk. Animal studies reveal it to be just as effective as the biological drugs currently in clinical use.
After decades of research aiming to understand how DNA is organized in human cells, scientists have shed new light on this mysterious field by discovering how a key protein helps control gene organization.
