Eating is one of life’s few constants: If you’re not eating right now, you’ll certainly be eating something within a few hours. But when and how often we should eat is still not fully understood.

Unlike the brain and spinal cord, peripheral nerve cells, whose long extensions reach the skin and internal organs, are capable of regenerating after injury. This is why injuries to the central ...

Like a phoenix rising from the ashes, our skin tissue—and in fact many types of epithelial tissue that lines and covers the ...

Planarians are a striking model for studying regeneration owing to their extraordinary capacity to reform entire body structures from small tissue fragments. This ability is mediated primarily by ...

Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different ...

A new study reported in Nature has determined that the amino acid cysteine could promote regeneration among cells in the small intestine. The work showed that cysteine can activate an immune signaling ...

While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ...

Scientists identify specific genes involved in zebrafish sensory hair cell regrowth, providing new insights that could inform future research into hearing loss treatments. While humans can regularly ...
