Synthetic cells used to bioengineer new forms of silica
(Phys.org) -- Scientists do not fully understand how nature uses proteins to develop new materials and minerals, but learning more about the natural processes could lead to bioengineering methods such as the biological synthesis ...
Single gene mutation can sweep through bacterial population, opening the door for the concept of 'species'
Bacteria are the most populous organisms on the planet. They thrive in almost every known environment, adapting to different habitats by means of genetic variations that provide the capabilities essential for survival. These ...

Restoring the function of a human cell surface protein in yeast cells
G protein-coupled receptors (GPCRs) are the largest and most diverse group of cell surface proteins in humans. These receptors, which can be seen as "traffic directors," transmit signals from the outside to the inside of ...

Worm genetics reveal important pathways for sleep regulation
Although the regulation of sleep—how much, when, and how sleep occurs—is mainly considered to be controlled by the brain, sleep deprivation also affects the body, and signals from the body can affect sleep. However, the ...
