Novel antibiotic deceives bacteria through mimicry
Most antibiotics need to penetrate their target bacteria. But Darobactin, a newly discovered compound, is much too large to do so. Nonetheless, it kills many antibiotic-resistant pathogens—by exploiting a tiny weak spot ...

Epigenetic regulator HP1a: Study reveals how DNA organizes itself in the nucleus
The DNA molecule is not naked in the nucleus. Instead, it is folded in a very organized way by the help of different proteins to establish a unique spatial organization of the genetic information. This 3D spatial genome organization ...

Shape-shifting Ebola virus protein exploits human RNA to change shape
The human genome contains the instructions to make tens of thousands of proteins. Each protein folds into a precise shape—and biologists are taught that defined shape dictates the protein's destined function. Tens of thousands ...

Protein can release trapped histones in the cell
In the cell nucleus, histones play a crucial role packaging DNA into chromatin. Histones are however very sticky to both DNA and RNA, so to ensure they are transported to the cell nucleus after synthesis and bind to the right ...
