In the minuscule world of nanotechnology, big steps are rare. But a recent development has the potential to massively improve our lives: an engine measuring 200 billionths of a metre, which could power tiny robots to fight diseases in living cells.
Ingredients crucial for the origin of life on Earth, including the simple amino acid glycine and phosphorus, key components of DNA and cell membranes, have been discovered at Comet 67P/Churyumov-Gerasimenko.
Researchers have created a programmable DNA thermometer that is 20,000x smaller than a human hair. One of the main advantages of using DNA to engineer molecular thermometers is that DNA chemistry is relatively simple and programmable.
Researchers have developed one of the first complete systems to store digital data in DNA -- allowing companies to store data that today would fill a big box store supercenter in a space the size of a sugar cube.
Eight percent of your DNA is alien, in that it�s made up of non-human, viral fragments. In fact, viral fragments are often hiding within the genome of anything on Earth that has a jaw and a spinal cord, which is a remarkable reminder of how they�ve shaped evolution for hundreds of millions of years.
Drug-resistant leukemia cells absorb a drug and die, when the drug is hidden inside a capsule made of folded up DNA.
The ancient origins, anatomical, linguistic and genetic distinctiveness of southern African San and Khoikhoi people are matters of confusion and debate. They are variously described as the world’s first or oldest people; Africa’s first or oldest people, or the first people of South Africa.
Presence of a gene variant involved in sensory pleasure and pain reduction may contribute towards making a population happier than others, suggests new research.
FOR ALL THE furious hype around the gene-editing tool Crispr/Cas9, no one has ever really seen it in action. Like really seen it. How the protein Cas9 unzips a strand of DNA, how it slips in the molecule that guides it to a target—and finally, how it goes snip snip on the DNA.
Scientists are one step closer to making more complex microscopic biological machines, following improvements in the way that they can
DNA, a molecule famous for storing the genetic blueprints for all living things, can do other things as well. In a new paper, researchers describe how tailored single strands of DNA can be used to purify the highly desired
Caltech scientists say they have built a rudimentary DNA
Researchers from the University of North Carolina (UNC) School of Medicine have identified the seventh and eighth bases of DNA. For decades, scientists
In a complex feat of nanoengineering, a team of scientists at Kyoto University and the University of Oxford have succeeded in creating a programable molecular transport system, the workings of which can be observed in real time. The results, appearing in the latest issue of Nature Nanotechnology, open the door to the development of advanced drug delivery methods and molecular manufacturing systems.
A Nobel Prize winning biologist has ignited controversy after publishing details of an experiment in which a fragment of DNA appeared to ‘teleport’ or imprint itself between test tubes.
