A new fluorescent sensor is giving scientists an unprecedented view of how cells respond to DNA damage, capturing the repair process as it unfolds in real time. The tool, developed at Utrecht ...

A protein long studied for its role in amyotrophic lateral sclerosis and frontotemporal dementia now appears to serve a second, equally critical function, safeguarding the integrity of human DNA.

In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an ...

Proteome-scale visual screening in budding yeast provides a functional catalog of plasma membrane repair proteins and reveals the coordinated cellular responses at the bud tip and the damage site.

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

NASA proposes to pioneer a radically new approach to mitigating radiation-induced cell damage in astronauts by transplanting new undamaged mitochondria (critical radiation-sensitive cell organelles) ...

Cellular injury entails disruptions in a cell's structure or function triggered by factors such as physical trauma, chemical exposure, infectious agents, and oxidative stress. These alterations may ...

Eye injuries that damage the cornea are usually irreversible and cause blindness. But a new clinical trial has repaired this damage in patients thanks to a transplant of stem cells from their healthy ...
