Nobel Prize winner Doudna shares perspectives on future of CRISPR gene editing
Small science can translate into big discoveries, according to Nobel Prize laureate Jennifer Doudna, PhD. She discussed how her curiosity in understanding CRISPR led to the gene editing revolution in a talk at the 2021 American Society of Gene & Cell Therapy virtual meeting. Read More
How the South African SARS-CoV-2 variant evades antibodies
Computer modeling has demonstrated that one of the three mutations of the South African SARS-CoV-2 variant reduces its ability to bind to human cells. The results, published recently in the Journal of Medicinal Chemistry, also suggest that the mutation may help it escape some therapeutic antibodies. Read More
New tool sheds light on transient protein interactions in cells
Researchers have developed a novel chemical tool for elucidating protein interaction networks within cells. The technique, details of which were published in Molecular Cell on April 23, allows for the visualization of protein-protein interactions. Read More
Naturally occurring molecule helps SARS-CoV-2 evade neutralizing antibodies
Researchers have identified naturally occurring molecules that are created from the breakdown of hemoglobin and block the binding of a subset of human antibodies to SARS-CoV-2. The discovery, published in Science Advances on April 22, may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus. Read More
Cell-free technique could enable on-demand vaccine production
A new cell-free synthetic biology technique that increases the volume of membrane components in the manufacture of conjugate vaccines can significantly improve the efficiency of vaccine production, according to a new method published in Nature Communications on April 22. The technology could enable on-site production of vaccines and therapies, enabling them to be more efficiently distributed in areas where they are most needed. Read More
Variant-resistant COVID-19 vaccines could be effective, cheap to make
Researchers have collaborated to create a new COVID-19 vaccine platform containing antigens against the fusion protein of the SARS-CoV-2 virus that could be effective against variants of the virus. The research was published online on April 15 in the Proceedings of the National Academy of Sciences. Read More
A CRISPR on-off switch for genes controls expression without altering DNA
A new gene silencing tool allows scientists to switch genes on and off without altering genetic sequences. The tool, described in a paper published in Cell on April 9, uses a modified CRISPR-Cas9 system to introduce reversible epigenetic changes that control gene expression. Read More
X-ray crystallography identifies drugs to be repurposed for COVID-19
A new large-scale study indicates x-ray crystallography can be used to find drugs that could be repurposed to target the SARS-CoV-2 main protease. In addition to identifying 37 potential drug candidates, the study, published in Science on April 2, revealed a new binding site on the SARS-CoV-2 main protease to which drugs can bind. Read More
Prime editing creates desired gene mutations without collateral damage
A new gene editing tool called prime editing was demonstrated to efficiently create cell-specific knockout mice compared to traditional gene editing techniques. While both platforms successfully created mutations, prime editing did so without measurable on-target indels or off-targeting events, according to a study published in Genome Biology on March 16.

Hydrogen maps of SARS-CoV-2 main protease point to effective repurposed drugs
Scientists have used atomic maps of hydrogen atoms to determine that the SARS-CoV-2 main protease acts in unexpected ways when it comes into contact with a drug inhibitor. The research, published in the Journal of Medicinal Chemistry on March 23, provides key insights for efforts to repurpose existing drugs to develop candidates for treating COVID-19. Read More
