Nanopore Sequences Genes Very First Time in Space, Courtesy NASA

Oxford Nanopore’s MiniION sequencers have successfully sequenced genes in space for the very first time at NASA’s International Space Station earlier this week. “One small step for genetic research, a huge step for space-exploration.” NASA has conducted feasibility of conducting genetic tests in microgravity conditions by using Oxford Nanopore’s USB sized MiniION genetic sequencers. The […]

CRISPR as a Recorder of Molecular Activity

Researchers from Harvard University have succesfully proved that CRISPR can work as a recorder of molecular events. Synthetic DNA molecules introduced in bacteria over a defined timespan were integrated by the CRISPR/Cas system in DNA arrays in the exact same order of introduction. The results, published in the journal Science, pave the way for using CRISPR to […]

An Exclusive Scientific Meeting Gives Birth to the Genome Project-Write

A select group of researchers from top American universities gathered last month in an invitation-only meeting at Harvard to discuss the need of technology and an ethical framework for genome-scale engineering. The conclusions are now presented in a paper published in the journal Science, where they propose to start the Human Genome Project–Write (HGP-write). In this call […]

CRISPR/Cpf1 Edits Mice Embryos Without Off-Target Effects

Researchers at the IBS Center for Genome Editing in South Korea have successfully created mutant mice using CRISPR/Cpf1. The alternative to the well-known CRISPR/Cas9 system can edit genomes with exquisite precision and is highly programmable. The findings -published in two papers that appeared this month in the journal Nature Biotechnology-, together with previously known advantages of Cpf1 over […]

Bacterial Hair Conducts Electricity and Could Be Used in Bioelectronic Devices

Scientists from the University of Massachusetts at Amherst, Holy Cross, and Brookhaven National Laboratory have discovered that the filaments present in the surface of Geobacter bacteria have conductive properties comparable to those of copper. The finding, published in the journal mBio, could accelerate the introduction of biological material in nanoscale electronical devices. In general, proteins are […]

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 […]

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 […]
