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 ...

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

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.

RNA is similar to DNA, but whereas DNA is long lived, RNA is a more transient molecule. A type of RNA, known as messenger RNA (mRNA), functions as the intermediate 'messenger' that carries ...

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

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

Researchers leverage their understanding of molecular motors to improve nanoscale artificial motors, aiming to bridge the ...

DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel ...

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