Scientists discover genes are controlled by 'nano footballs'
Research at the University of York has revealed that genes are controlled by 'nano footballs' - structures that look like footballs but 10 million times smaller than the average ball.

Regenerating tissues with gene-targeting molecules
A synthetic DNA-targeting molecule could pave the way for tissue regeneration.
10,000 year-old DNA proves when fish colonized lakes
DNA molecules in lake sediment are few and hard bound to particles. This resulted in challenging analyses and required development of new methods, both for extracting sufficiently clean DNA and for the statistical analysis ...
Copying nature's lock-and-key system could improve rapid medical diagnostics
Researchers have designed a system that rapidly recognises the specific biological molecules that can indicate disease.
A new way to create 'soft robots'—DNA triggers that cause hydrogels to change shape
Biochemical engineers at Johns Hopkins University used sequences of DNA molecules to cause water-based gels to change shape, demonstrating a new tactic to produce soft robots and "smart" medical devices that don't rely on ...
Could interstellar ice provide the answer to birth of DNA?
Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA.
Innate immunity—to operate, insert dimers
The presence of DNA in mammalian cell cytoplasm triggers an immune response by binding to a dimeric enzyme, which inserts between DNA double helices to form the 'rungs' of a ladder-like structure, as an LMU team has now shown.
Study of circular DNA comes full circle with use of old technique
A 50-year-old lab technique is helping researchers better understand circular DNA, a lesser-known and poorly understood cousin of the linear version commonly associated with life's genetic blueprint.
Biophysics study makes exciting advancements for the future of DNA sequencing
A Northeastern research team has developed new technology that optimizes DNA sequencing using nanophysics and electric currents. In a paper published in Nature Nanotechnology, Northeastern Professor of Biological Physics ...
Chromosome motor discovery supports DNA loop extrusion
It is one of the great mysteries in biology: How does a cell neatly distribute its replicated DNA between two daughter cells? For more than a century, we have known that DNA in the cell is comparable to a plate of spaghetti—a ...
