Ancient protein-making enzyme moonlights as DNA protector

Scientists at The Scripps Research Institute (TSRI) have found that an enzyme best known for its fundamental role in building proteins has a second major function: to protect DNA during times of cellular stress.

Gravity plays a role in keeping cells small

(Phys.org) —The effects of gravity are relevant when building houses or flying airplanes, but biologists have generally accepted that the average cell is too small for gravity to play a role in how it is built or behaves. ...

Histone exchanger comes into focus

The packaging of a gene has a major impact on its functional state and must be precisely controlled. A novel blend of methods has unveiled the architecture of a large protein complex that modulates DNA packing, and hints ...

Cells eat themselves into shape

The process cells use to 'swallow' up nutrients, hormones and other signals from their environment – called endocytosis – can play a crucial role in shaping the cells themselves, scientists at the European Molecular Biology ...

This fungus cell only looks like the 405 freeway (w/ Video)

No, those are not cars darting along a busy highway. The glowing specks you're seeing in the video are millions of nuclei flowing through the tube-like filaments, or hyphae, of a single fungus cell.

Clones of clones can make clones

Since the first reports of successful cloning of mammals by somatic cell nuclear transfer, concerns have been raised about the efficiency and repeatability of cloning techniques, and the health of cloned offspring. Although ...

Lost frog DNA revived

As part of a "Lazarus Project" to try to bring the Australian gastric-brooding frog back from extinction a UNSW-led team has succeeded in producing early stage cloned embryos containing the DNA of the frog, which died out ...

Scientists study transient degradation of an actin regulator

Scientists at the Center for Molecular Biology of Heidelberg University have gained new insight into the process of mitosis in mammalian cells. Researchers under the direction of Prof. Dr. Frauke Melchior, in collaboration ...
