CRISPR systems are powerful tools for genetic engineering, but they have their limitations. Now, scientists have discovered almost 200 new CRISPR systems in their native habitat of bacteria, and found ...

Bacteria-attacking viruses, known as bacteriophages, use small RNAs to disarm the CRISPR-Cas immune systems of bacteria. This discovery has now been documented by researchers at the University of ...

In the second new research review on this subject, Assistant Prof. Ibrahim Bitar, Department of Microbiology, Faculty of Medicine and University Hospital in Plzen, Charles University in Prague, Plzen, ...

CRISPR, the gene-editing technology which won its creators the 2020 Nobel Prize for Chemistry, is most well-known for its ...

2023 was the year that CRISPR gene-editing sliced its way out of the lab and into the public consciousness—and American medical system. The Food and Drug Administration recently approved the first ...

During her chemistry Nobel Prize lecture in 2018, Frances Arnold said, “Today we can for all practical purposes read, write and edit any sequence of DNA, but we cannot compose it.” That isn’t true ...

The idea that a single-celled bacterium can defend itself against viruses in a similar way as the 1.8-trillion-cell human immune system is still “mind-blowing” for molecular biologist Joshua Modell of ...

Using CRISPR, an immune system bacteria use to protect themselves from viruses, scientists have harnessed the power to edit genetic information within cells. In fact, the first CRISPR-based ...

Antibiotics usually save lives—but against some bacteria, they can make things worse. That’s the case with the Shiga toxin–producing Escherichia coli, where bacterial death releases a flood of a ...

In the never-ending quest to discover previously unknown CRISPR gene-editing systems, researchers have scoured microbes in everything from hot springs and peat bogs to poo and even yogurt. Now, thanks ...

Evo’s success wasn’t limited to proteins. When they tested a different toxin that had an RNA-based inhibitor, the system ...

Turning off the genetic switch to its respiratory system might finally eliminate the bacteria behind tuberculosis.
