In a typical cell, genes encoded in DNA are used to make messenger RNA (mRNA), which is used to make proteins, and this process of gene expression keeps the cell running. Gene expression is regulated in each cell such that ...

Single-celled organisms, such as bacteria and archaea, have developed many ways to communicate with each other. For example, they might use tiny so-called extracellular vesicles (EVs)—membrane-enveloped packages smaller ...

In a new Nature Communications study, researchers have explored the construction of genetic circuits on single DNA molecules, demonstrating localized protein synthesis as a guiding principle for dissipative nanodevices, offering ...
In today's aging societies, bone and joint diseases are becoming increasingly common. For example, in Japan alone, over 12 million people suffer from osteoporosis, a condition that severely weakens bones and makes them fragile. ...
