Researchers have developed synthetic genes that function like the genes in living cells. The artificial genes can build intracellular structures through a cascading sequence that builds ...

An essential component of the lymphatic system, the thymus, a pyramid-shaped organ located in the thoracic cavity, is responsible for producing T-cells. For centuries, the thymus was believed to be an ...

To function correctly, cellular proteins depend not only on their complex tertiary and quaternary structures, but also on their proximity to and interactions with other molecules participating in the ...

More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the origin of life itself—this merger radically changed the ...

Human cells are extremely small and tightly packed – at about 20 micrometers across, ...

The cochlea is the spiral-shaped structure within the inner ear responsible for our sense of hearing. To fully understand hearing functions and open the door to new hearing loss treatments, scientists ...

In A Nutshell As cells age, they deliberately shrink a major internal structure called the endoplasmic reticulum. This downsizing happens early in adulthood and shifts cells away from protein ...

Custom polymer structures can now be 3D printed inside living cells using laser-based fabrication, opening paths to intracellular sensors, cell tracking tags, and embedded microlasers. (Nanowerk ...
