Random mutations turn RNA droplets into cell-like structures that move and store cargo
المصدر: Phys.org - latest science and technology news stories · نُشر
A small number of random genetic mutations cause simple RNA droplets to transform into cell-like structures. In this process, they form cavities, can move and are able to take up cargo.

How cells make their command center accessible
The cells of higher organisms such as mammals, flies and fungi enclose their genetic material in a nucleus. A nuclear envelope, consisting of two stacked membranes, protects it. For the cell to survive, the nucleus must constantly exchange molecules with the rest of the cell. Thi

Copper-resistant bacteria complicate efforts to keep ship hulls clean
Marine bacteria have evolved to bypass the copper-based coatings applied to ship hulls to stop the growth of barnacles, algae and other marine life. This necessitates new methods for managing biofouling—the unwanted accumulation of marine organisms—on ship hulls.
