Towards the ultimate model of water

Researchers from the National Physical Laboratory (NPL), IBM and the University of Edinburgh have developed the first conceptually simple but broadly applicable model for water.

Video imaging of single molecule DNA replication

Almost all life on Earth is based on DNA being copied, or replicated. Now for the first time scientists have been able to watch the replication of a single DNA molecule, with some surprising findings. For one thing, there's ...

Study shows how DNA finds its match

It's been more than 50 years since James Watson and Francis Crick showed that DNA is a double helix of two strands that complement each other. But how does a short piece of DNA find its match, out of the millions of 'letters' ...

A new model for simulating DNA's 'atmosphere' of ions

Nucleic acids, large biomolecules essential to life, include the familiar double-stranded deoxyribonucleic acid (DNA), a very stable long molecule that stores genetic information.

Breaking bonds: Double-helix unzipping reveals DNA physics

Accurately reconstructing how the parts of a complex molecular are held together knowing only how the molecule distorts and breaks up—this was the challenge taken on by a research team led by SISSA's Cristian Micheletti ...

Researchers find gold nanoparticles capable of 'unzipping' DNA

New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA's double helix. This finding has ramifications for gene therapy research and the ...

DNA-based electromechanical switch demonstrated

A team of researchers from the University of California, Davis and the University of Washington have demonstrated that the conductance of DNA can be modulated by controlling its structure, thus opening up the possibility ...

'Sticky waves'—molecular interactions at the nanoscale

Like the gravitational forces that are responsible for the attraction between the Earth and the moon, as well as the dynamics of the entire solar system, there exist attractive forces between objects at the nanoscale.

Biologists reveal how gyrase resolves DNA entanglements

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 every cell in the body ...
