The image shows motor neurons that have been generated from human iPSC (induced pluripotent stem cells) and integrated into a 3D-printed bioscaffold. The cells (shown in red) grow inside the ...

A tickly itch, a painful scratch, or the feeling of a refreshing breeze—the skin is teaming with nerve endings that drive these sensations. Scientists are getting into the epidermis to explore how ...

Most human nerve cells last a lifetime without renewal. A trait echoed within the cells' components, some enduring as long as the organism itself. Most human nerve cells last a lifetime without ...

No less than 16 different types of nerve cells have been identified by scientists in a new study on the human sense of touch. Comparisons between humans, mice and macaques show both similarities and ...

Oregon Health & Science University researchers have found that certain nerves that play an integral role in the body's "fight or flight" stress response can support pancreatic tumor growth. These ...

The video I am watching feels like a scene from a horror movie. At the centre of the screen is a blood-red mass – in reality, a massively magnified pancreatic tumour, vividly dyed as if to highlight ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. Billions of nerve cells send signals coursing through our bodies, serving as conduits ...

Contrary to historic understanding of RNA’s longevity in cells, some RNAs can persist in cells throughout the life of an organism. Lead authors, Martin Hetzer, PhD, president of the Institute of ...
