Rsearchers have succeeded in preventing cystic fibrosis lung disease in an animal model by spraying amiloride into the lungs of young mice. This is the first therapy to successfully attack the root cause of the widespread hereditary disease in a living organism. When mice are given inhalation treatment with the drug in the first days [...]

Domain walls that conduct electricity, mere billionths of a meter wide, could be the ultimate nanoscale feature for future electronics. Scientists have not only discovered conducting domain walls — never seen before — but learned how to write, erase, and manipulate them.

Stem cells of any kind are defined by their eternal nature, reproducing themselves and providing a pool of cells from which more differentiated tissues arise. Now researchers demonstrate that two specific “sister” genes that control transcription play often overlapping roles in maintaining this pool of hematopoietic or blood cell-forming stem cells.
