DNA evolved to store genetic information, but in principle this special, chain-like molecule can also be adapted to make new materials. Chemists at The Scripps Research Institute (TSRI) have now published an important demonstration of this repurposing of DNA to create new substances with possible medical applications.
A DNA nanorobot is programmed to pick up and sort molecules into predefined regions.
There has been rapid improvement in the cost and time necessary to sequence and analyze DNA. In the past decade, the cost to sequence a human genome has decreased 100,000 fold or more. This rapid improvement was made possible by faster, massively parallel processing. Modern sequencing techniques can sequence hundreds of millions of DNA strands simultaneously, resulting in a proliferation of new applications in domains ranging from personalized medicine, ancestry, and even the study of the microorganisms that live in your gut.
For the first time, a primitive movie has been encoded in — and then played back from — DNA in living cells. Scientists funded by the National Institutes of Health say it is a major step toward a “molecular recorder” that may someday make it possible to get read-outs, for example, of the changing internal states of neurons as they develop.
Every human being has a unique DNA "fingerprint". In other words, the genetic material of any two individuals can be clearly distinguished. Computational biologists at the Technical University of Munich (TUM) have now determined that the impact of these variations has been greatly underestimated. The new insights could importantly impact advances in personalized medicine.
The first fully automated machine to convert digital code into functional biologics without human intervention creates entirely new avenues for precision medicine
Almost all life on earth is based on DNA being copied, or replicated, and understanding how this process works could lead to a wide range of discoveries in biology and medicine. Now for the first time scientists have been able to watch individual steps in the replication of a single DNA molecule, with some surprising findings. For one thing, there’s a lot more randomness at work than has been thought.
