Roberto Weigert is a cell biologist who specializes in intravital microscopy (IVM), an extremely high-resolution imaging tool that traces its origins to the 19th century. What’s unique about IVM is its phenomenal resolution can be used in living animals, allowing researchers to watch biological processes unfold in organs under real physiological conditions and in real time.

For gene therapy research, the perennial challenge has been devising a reliable way to insert safely a working copy of a gene into relevant cells that can take over for a faulty one. But with the recent discovery of powerful gene editing tools, the landscape of opportunity is starting to change. Instead of threading the needle through the cell membrane with a bulky gene, researchers are starting to design ways to apply these tools in the nucleus—to edit out the disease-causing error in a gene and allow it to work correctly.

Ever since the discovery of the double-helix structure of DNA, scientists have sought ways to edit the genome. Altering gene expression partially and transiently via small interfering RNA has come a long way, and the progress has been spectacular. However, achieving complete and sustained modification of gene expression in a cell remains a tedious procedure that is often costly and time-consuming. For molecular biologists working with cell lines, quick and efficient knock out of one or more genes would provide a powerful tool for their studies. The CRISPR technology arrived two years ago to potentially fulfill that need.

I have been thinking a lot recently about how the tools we use in our work have improved so dramatically in the last few decades and how this is mostly down to the frequently disparaged study of microbes. While everyone can get behind studying bacteria that cause life-threatening diseases like typhoid fever and cholera, I think that it is often harder to convince people of the value of studying ordinary and sometimes obscure bacteria that do not directly affect human health. However, over the years, such studies have revolutionized many aspects of our lives.
