The world's tiniest thermometer is made from DNA

Researchers at the University of Montreal have created a thermometer that's an astonishing 20,000 times smaller than a single human hair. The work could lead to significant improvements in our understanding of how the human body functions on the nanoscale.Read More


DNA sequence behind muscle regeneration begins to unravel

Animals that regrow body parts like zebrafish and newts certainly function very differently to the way humans do, but we might one day be able to borrow some of these traits. A closer look at the mechanism driving these remarkable regenerative abilities has suggested that they could be recreated in mice, with the scientists involved hopeful it could ultimately improve our capacity to regrow damaged body parts.Read More


World's smallest diode made from a single DNA molecule

As electronic devices become ever more complex, and the densities of components in those devices increases exponentially, we are rapidly approaching the day when the limitations of Moore's Law will be realized. In an effort to avert this eventuality, research has concentrated on moving away from traditional silicon technologies and into the realms of molecule-sized components and alternative materials. In this vein, researchers at the University of Georgia (UGA) and Ben-Gurion University in Israel have, for the first time, created a nanoscale electronic diode from a single DNA molecule.

Genomic signature could lead to new early-detection cancer test

Detecting cancer when it's still in the early stages of development is a difficult task, but an extremely important one, with the chances of effective treatment being much higher the quicker it's caught. Now, a team of researchers from the National Institute of Health (NIH) has identified a signature of tumor DNA that occurs, and is detectable, in five different cancers – a discovery that could lead to a simple early detection blood test.Read More


Improved DNA tech could replace antibodies in detecting and treating diseases

A team of researchers from the Institute of Bioengineering and Nanotechnology at the Agency for Science, Technology and Research (A*STAR) has worked to develop an efficient technology that uses DNA to detect and treat infectious diseases. Improving upon an existing method, the research makes use of single-stranded DNA molecules called aptamers, and it could be used to treat cancer.Read More

DNA analysis may provide early warning of breast cancer

It could be possible to look for molecular alternations in breast tissue to identify whether a patient is at risk of developing breast cancer, a new study has found. Scientists at University College London (UCL) looked at changes in patient DNA, finding clear evidence that epigenetic alterations play a part in the occurrence of the disease.Read More
