Scientists combine CRISPR and drug therapy to cure HIV infection in mice for the first time

Nick Lavars July 2, 2019

A permanent cure for HIV has remained elusive. But scientists have now made a significant breakthrough in this area, using the CRISPR-Cas9 gene editing tool to entirely remove the virus from the genomes of living animals for the first time ever.

Using a novel combination of a new drug therapy and the CRISPR gene editing tool, scientists ...

New CRISPR-based system inserts new DNA without cutting and pasting

Michael Irving June 12, 2019

The CRISPR gene-editing system is a powerful tool, but sometimes cutting and pasting can have unwanted side effects. Now researchers from MIT and Harvard have developed a new CRISPR-based system that can insert new DNA sequences without cutting, which should make the process safer and more accurate.

Chinese CRISPR gene-edited babies at risk of early death

Rich Haridy June 3, 2019

A massive genome study by two scientists from UC Berkeley has found the CRISPR gene edit, administered by a Chinese scientist last year that led to the birth of two healthy babies, may be associated with a higher rate of early mortality in later life.

A large study of people with the same genetic mutation introduced by Chinese scientists He Jiankui ...

Anti-CRISPR molecules discovered that can block the gene editing technology

Rich Haridy May 2, 2019

New work from the Broad Institute and Brigham and Women's Hospital has presented a study that homes in on small molecules that may have the ability to safely block the CRISPR gene editing process.

Newly discovered anti-CRISPR molecules can quickly inhibit the activity of the CRISPR-Cas9 gene editing process

CRISPR used to build dual-core computers inside human cells

Michael Irving April 17, 2019

The CRISPR gene-editing system is usually known for helping scientists treat genetic diseases, but the technology has a whole range of possible uses in synthetic biology too. Now researchers at ETH Zurich have used CRISPR to build functional biocomputers inside human cells.

CRISPR breakthrough uses "hairpin lock" for more precise genetic engineering

Michael Irving April 16, 2019

The CRISPR gene-editing system is incredibly accurate, but it’s not unusual for it to be a little bit off target sometimes. Now, biomedical engineers at Duke University have created an RNA “lock” that can apparently make the system far more precise, and it works with all kinds of CRISPR variations.

The new hairpin lock – blue section at the top left – folds back on itself ...

A DNA "shredder" is the latest CRISPR gene-editing tool

Michael Irving April 9, 2019

CRISPR-Cas9 acts like a pair of molecular scissors and enables precise cut-and-paste DNA edits. But now, researchers have developed a new genetic tool that, they say, acts more like a motorized DNA “shredder.”

A new gene-editing enzyme called CRiSPR-Cas3 could function like a "DNA shredder"

World's first gene-edited lizards are in the pink

Ben Coxworth April 4, 2019

Although they're commonly known as brown anoles, there are now four Anolis sagrei lizards at a University of Georgia lab that are actually pink. They're the result of the world's first successful attempt at producing a genetically modified reptile. The research could have implications for humans.

WHO calls for global gene editing research registry as debate over moratorium rages

Rich Haridy March 24, 2019

Following a recent call for a moratorium on human germline gene editing, several scientists have pushed back, claiming prohibition is redundant and problematic. The WHO's panel on the topic also sidestepped the issue, instead recommending a central registry on human gene editing research be created.

Some scientists suggest a moratorium on gene editing is an unnecessary distraction from the regulatory conversation ...

Coalition of scientists and ethicists call for immediate moratorium on human gene editing

Rich Haridy March 13, 2019

A collective of researchers and ethicists is calling for an urgent global moratorium on human germline gene editing, suggesting serious discussions on technical, scientific, medical, societal, ethical and moral issues need to be had before scientists move forward with the controversial technique.

Over a dozen influential scientists are presenting a proposal for a temporary moratorium on human gene ...
