New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

Homologous recombination is a DNA repair mechanism that counteracts double-stranded breaks in DNA. Researchers at Kindai University have recently revealed how the Sae2 protein coordinates with the ...

In a recent study published in the journal Nature, researchers found that the recruitment of neurons to memory circuits is preceded by a cascade of molecular events induced during learning, which ...

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 ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Cancer research, drug safety testing and aging biology may all gain a major boost from a new fluorescent sensor developed at Utrecht University. This new tool allows scientists to watch DNA damage and ...

A clump of proteins seems to be in charge of the level of DNA repair that takes place in our bodies, determining how fast mutations accumulate in our cells over a lifetime – and might thus affect our ...

Naked mole-rats are well known for both their wrinkly appearance and for their unexpectedly long lives. The source of this extended lifespan has been under scrutiny for decades. While many rodents are ...
