'Quadruple helix' DNA discovered in human cells
In 1953, Cambridge researchers Watson and Crick published a paper describing the interweaving 'double helix' DNA structure - the chemical code for all life. Now, in the year of that scientific landmark's 60th Anniversary, ...
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.
Charged graphene gives DNA a stage to perform molecular gymnastics
(Phys.org) —When Illinois researchers set out to investigate a method to control how DNA moves through a tiny sequencing device, they did not know they were about to witness a display of molecular gymnastics.
'Atomic chicken-wire' is key to faster DNA sequencing
An unusual and very exciting form of carbon - that can be created by drawing on paper- looks to hold the key to real-time, high throughput DNA sequencing, a technique that would revolutionise medical research ...
Study shows novel pattern of electrical charge movement through DNA
Electrical charges not only move through wires, they also travel along lengths of DNA, the molecule of life. The property is known as charge transport.
Engineers invent programming language to build synthetic DNA
Similar to using Python or Java to write code for a computer, chemists soon could be able to use a structured set of instructions to "program" how DNA molecules interact in a test tube or cell.
Study shows where damaged DNA goes for repair
A Tufts University study sheds new light on the process by which DNA repair occurs within the cell. In research published in the May 15 edition of the journal Genes & Development and available May 4 onli ...
Relaxation helps pack DNA into a virus
Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published ...
New material could enhance fast and accurate DNA sequencing
Gene-based personalized medicine has many possibilities for diagnosis and targeted therapy, but one big bottleneck: the expensive and time-consuming DNA-sequencing process.
New method sneaks drugs into cancer cells before triggering release
(Phys.org) —Biomedical engineering researchers have developed an anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release. The method can be likened ...
New type of extra-chromosomal DNA discovered
DNA-linked nanoparticles form switchable 'thin films' on a liquid surface
Scientists seeking ways to engineer the assembly of tiny particles measuring just billionths of a meter have achieved a new first—the formation of a single layer of nanoparticles on a liquid surface where ...
The final nail in the Jurassic Park coffin: Next generation sequencing reveals absence of DNA in sub-fossilized insects
It is hardly possible to talk about fossil insects in amber without the 1993 movie Jurassic Park entering the debate. The idea of recreating dinosaurs by extracting DNA from insects in amber has held the ...
Physicists build highly efficient 'no-waste' laser
A team of University of California, San Diego researchers has built the smallest room-temperature nanolaser to date, as well as an even more startling device: a highly efficient, "thresholdless" laser that ...
