How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals ...

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

When environmental stress harms DNA, it can set off a cascade of failures linked to heart conditions, neurodegeneration, and ...

What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this mystery. Their experiments show that ribose binds more readily and ...

Researchers have designed a chemical probe to bind damaged mitochondrial DNA, halting the enzymatic processes that lead to ...

These edits modify RNA, the molecule used to translate information from the genetic blueprint stored in DNA, while leaving the DNA unaltered. Scientists don’t yet know for sure why octopuses ...

Now, scientists at the University of California, Riverside, may have found a way to halt the damage before it begins. The ...
