Scientists at the University of California San Diego have created a new version of a gene drive which could lead to spreading specific, favourably genetic variants through a population. This “allelic drive” uses a guide RNA to direct CRISPR to cut undesired gene variants and replace them with better versions of the gene.
An international team of scientists has developed a new gene editing tool which goes beyond the usual mechanisms of CRISPR, acting instead as a “shredder” which can delete large stretches of DNA with programmable targeting. The technology was also shown to work in human cells for the first time.
For the first time, CRISPR-Cas9 has been combined with electronic graphene transistors to create a new handheld device which can detect specific mutations in the genome within minutes. The device can be used to quickly diagnose genetic disorders and diseases or determine the accuracy of gene-editing techniques.
The scientists of seven nations have called for a halt to gene-editing experiments seeking to alter heritable traits in human babies.
A neuron-optimised CRISPR-Cas9 activation system has been used by scientists to regulate genes in a rat brain for the first time. This technique could lead to researchers being able to probe genetic influences on brain health and disease in model organisms which more closely resemble humans.
New information from China has suggested that the twins recently created using CRISPR gene-editing technology to make them HIV-resistance could also develop genetically-enhanced brains.
Researchers from the Wake Forest Institute for Regenerative Medicine (WFIRM) have determined a new way to deliver DNA editing tools so that the presence of their proteins in cells is reduced, in what they have called a “hit and run” approach.
For the first time, scientists have changed human stem cells into functional insulin-producing cells in mice, potentially promising a breakthrough in treatment for those suffering from type 1 diabetes.
The introduction of multi-omic research, the advancement of AI and machine learning to improve nearly every aspect of sequencing and data analysis, are just some of the big changes that will only become more prevalent in the future. We spoke to Angela Douglas MBE, Scientific Director of Genetics Laboratories at Liverpool Women’s Hospital, for her opinions on the changing nature of genomics and the trends to watch out for.
With so many talks and panels occurring across our four stages and Live Lounge, we understand that it can be pretty hard to pick out the most unmissable discussions at the festival this year. Given the conundrum, we thought we’d help out! We’ve selected a couple of talks and panels occurring across the two days which we think will be incredibly interesting and enormously informative for a whole range of people.
A new study published in Cell magazine and co-authored by CRISPR pioneer Jennifer Doudna has suggested a potential solution to the unwanted side-effects of using CRISPR in the body. The study details using a “switch” mechanism which could keep the Cas9 enzyme turned off until it reaches its target site.
A CRISPR study has determined how DNA times its own replication, something which until now has been unknown to scientists.
A modified version of CRISPR has been used to reverse genetic obesity in two different mouse models without editing any genes. The technique uses the guidance system in CRISPR to target certain genetic sequences and amplifies existing gene activity to ramp up protein production.
The CCR5 gene has been researched by scientists since the 1990s, and has a number of roles which have not yet properly been uncovered. Loss of the gene’s function is known, however, to increase the risk of potentially fatal reactions to some diseases, and has shown an ability to enhance learning in mice.
