DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...

An illustration shows a strand of engineered DNA passing through a nanoscale sensor, where its physical structure can be decoded as digital information. DNA nanostructures could one day serve as ultra ...

Since the dawn of the computer age, researchers have wrestled with two persistent challenges: how to store ever-increasing reams of data and how to protect that information from unintended access. Now ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

How much of our genome really matters? Some argue that because most of our DNA is active, it must be doing something important. Others say even random DNA would be highly active. This has now been put ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. In 1976, workers excavating a tunnel for the Toronto subway system ...

Scientists searching for novel ways to fight cancer think they may have uncovered a promising new lead tucked away inside the cells of the bowhead whale. The findings, published in the journal Nature, ...

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...

Johnson and Alistar competed as finalists in CU Boulder’s 2025 Lab Venture Challenge where their technology generated much interest from industry leaders. Access to DNA is crucial in many branches of ...

Researchers have analyzed a sample of DNA believed to belong to Adolf Hitler, which they say reveals the dictator of Nazi Germany had a genetic marker for a rare disorder that can delay puberty, ...
