Activating a new understanding of gene regulation

Regulation of gene expression—turning genes on or off, increasing or decreasing their expression—is critical for defining cell identity during development and coordinating cellular activity throughout the cell's lifetime. ...

Making nanowires from protein and DNA

The ability to custom design biological materials such as protein and DNA opens up technological possibilities that were unimaginable just a few decades ago. For example, synthetic structures made of DNA could one day be ...

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 ...

Functional nerve cells from skin cells

A new method of generating mature nerve cells from skin cells could greatly enhance understanding of neurodegenerative diseases, and could accelerate the development of new drugs and stem cell-based regenerative medicine.

Criticality in morphogenesis

(Phys.org) —In many regards, a brief time-lapse video can teach more about embryonic development than any amount of reading. It is hard not to be impressed how a repeatable form reliably emerges despite considerable variation ...
