Tiny robots could serve all kinds of useful functions, but shrinking their actuators has proven challenging. Now researchers at the University of Wollongong (UOW) in Australia have made artificial ...

The double helix of DNA is one of the most iconic symbols in science. By imitating the structure of this complex genetic molecule we have found a way to make artificial muscle fibers far more powerful ...

A team of physicists working at the intersection of theory and experiment are shedding new light on the 'teamwork' of molecular motors -- called RNA polymerases (RNAPs) -- that mediate DNA ...

A team of physicists working at the intersection of theory and experiment are shedding new light on the “teamwork” of molecular motors—called RNA polymerases (RNAPs)—that mediate DNA transcription.

Researchers from Durham University, Jagiellonian University (Poland) and the John Innes Centre have achieved a breakthrough in understanding DNA gyrase, a vital bacterial enzyme and key antibiotic ...

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...

A cell has many ways to regulate gene expression, one of which is the structure of the genome itself; active genes have to be accessible to the cellular machinery to be expressed. The DNA in the ...

Picture in your mind a traditional “landline” telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in ...

At the end of 2023, the FDA approved Casgevy for sickle cell disease, its first approval for a therapeutic that used the genome editing tool clustered regulatory interspaced palindromic repeats ...
