New CRISPR Nuclease Cuts Both DNA and RNA

CRISPR/Cas9 co-discoverer Emmanuelle Charpentier and collaborators from Germany and Sweden have found that Cas nuclease Cpf1 cleaves DNA and RNA. Cpf1 cuts a precursor of crRNA to produce the mature form; it requires only one RNA strand to cleave the target DNA and is smaller that Cas9. The findings were published in the journal Nature. CRISPR/Cas systems have been […]

Nanothermomether Built with DNA

Illustration: istockphotos   Researchers from the University of Montreal have designed a DNA thermometer 20000 times smaller than a human hair. The scientists took advantage of DNA’s natural changes in compaction when subject to temperature variations. The DNA thermometer, which measures temperature at the nanoscale, serves as a proof of concept for building new nanodevices. […]

Digital Images Can Be Stored in DNA

Researchers from the University of Washington (UW) and Microsoft have developed a new system to store data in DNA and retrieve it without error or information loss. The findings were communicated in a paper presented at the ACM International Conference on Architectural Support for Programming Languages and Operating Systems. The UW team encoded the digital data corresponding to image […]

BioViva’s CEO Claims to Have Longer Telomeres After Gene Therapy

BioViva reported last week that the company’s CEO, Elizabeth Parrish, successfully reversed biological ageing after being treated with the biotech’s therapies. The Seattle-based company confirmed that Parrish reversed 20 years of telomere shortening thanks to an experimental gene therapy. BioViva aims to provide regenerative medicine solutions through gene and cell therapies. The company is involved in several research lines to […]

A More Precise Nanopore Sequencer Based on Polymer-Tagged Nucleotides

Researchers from Columbia University School of Engineering and Applied Science have developed an advanced real-time, single-molecule nanopore sequencer. In collaboration with Genia Technologies (Roche), Harvard University and the National Institute of Standards and Technology (NIST), the engineers built an electronic DNA sequencer with better resolution than current nanopore devices. The study was published in the journal PNAS. Genome sequencing has allowed […]

CRISPRainbow Allows to Tag Seven Genomic Loci Simultaneously

Researchers from University of Massachusetts Medical School have developed a new technique to simultaneously track up to seven genomic locations in live cells. The CRISPRainbow system is based on the genomic editing tool CRISPR/Cas9. The study was published in the journal Nature Biotechnology. The three-dimensional structure of the genome has important consequences in gene expression. Genes can […]
