A study reveals DNA and RNA epigenetics work together as a complementary system for precise gene regulation, crucial for cell ...

For decades, we’ve believed the bright redness of sunburn — along with its irritating sting and peeling skin — was the result of ultraviolet (UV) radiation wreaking havoc on DNA. But now, a new study ...

NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission.

Sunburn has traditionally been attributed to UV-induced DNA damage. However, a new study reveals that RNA, another vital cellular molecule, plays a major role in triggering acute sunburn reactions.

"Sunburn damages the DNA, leading to cell death and inflammation. So the textbooks say. But in this study we were surprised to learn that this is a result of damage to the RNA, not the DNA that ...

This is where DNA and RNA epigenetics comes in: a series of mechanisms that act as "markers" on genes, to control their activity without modifying the DNA or RNA sequence itself. Until now, DNA and ...

Most people associate sunburns with DNA damage -- it's what we've been taught in textbooks and by dermatologists for years.

Researchers have optimized DNA-nanoparticle motors to achieve speeds of 30 nm/s, matching natural motor proteins. By ...
