Prime editing – a cutting edge new development in genomic engineering

Most biologists would agree that the most extraordinary development of the 21st century has been the discovery and manipulation of the CRISPR/Cas9 method of gene editing – a natural defence mechanism that bacteria use to defend against viral infection which scientists have hijacked to modify the DNA sequence of living cells.

Some Bacteria Use Tiny Biological Needles to Make Us Sick!

There are many bacteria all around us, some are beneficial while others can cause disease. The way in which different bacteria cause disease are varied. Some bacteria use a certain infection mechanism known as the type III secretion system which functions just like a tiny biological needle.
