Ultraviolet (UV) radiation is known to cause DNA damage, and while that damage may accumulate and eventually lead to diseases like skin cancer, cells also have repair mechanisms that can fix ...

Sun damage can start within minutes. Learn how quickly it happens, what factors influence your risk, and how to protect your ...

In a recent study, researchers suggest the cell's messenger RNA (mRNA) -- the major translator and regulator of genetic material -- along with a critical protein called ZAK, spur the cell's initial ...

New research links actinic keratosis to microbiome imbalance and inflammation, highlighting new therapeutic targets. Read ...

While we all benefit from some exposure to the sun, the sun's rays are known to be harmful when we aren't protected; UV radiation in sunlight can damage DNA. But scientists have now also determined ...

New research reveals that sunburn may be caused by RNA damage, not DNA, challenging long-held beliefs about UV exposure.

From proofreading polymerases to complex backup repair systems, DNA repair is a high-yield MCAT topic that bridges molecular biology and human health. Understanding the mechanisms that safeguard ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American The life-giving sun can be quite rough on ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

UV radiation damage can force an injured cell to decide between survival and cellular suicide. New research from Rachel Green's laboratory shows DNA isn't the only trigger. Immediately after UV ...
