The clouds of spaghetti that keep DNA data safe

Cells can avoid "data breaches" when letting signaling proteins into their nuclei thanks to a quirky biophysical mechanism involving a blur of spaghetti-like proteins, researchers from the Rockefeller University and the Albert ...

Reprogramming the oocyte

(Phys.org)—Among other things, the egg is optimized to process the sperm genome. The cytoplasmic factors that make this possible also give the egg the ability to reprogram the nuclei from other kinds of cells if these nuclei ...

Protein-engineered cages aid studies of cell functions

Carbon monoxide (CO) plays an important role in cell functions, by signalling responses that counteract inflammation, and cell growth and death. As a result, researchers have been in pursuit of molecules that release CO into ...

How steroid hormones enable plants to grow

Plants can adapt extremely quickly to changes in their environment. Hormones, chemical messengers that are activated in direct response to light and temperature stimuli help them achieve this. Plant steroid hormones similar ...

Nuclear pore complexes harbor new class of gene regulators

Nuclear pore complexes are best known as the communication channels that regulate the passage of all molecules to and from a cell's nucleus. Researchers at the Salk Institute for Biological Studies, however, have shown that ...
