A New CRISPR Tool Flips Genes On and Off Like a Light Switch

Share This Post

A team from the University of California, San Francisco worked on gene editing tool CRISPR to observe whether its process can be reversible. Using light switches as illustration, the team began by engineering a CRISPR system, dubbed CRISPRoff, that would shut down any targeted gene without ripping the DNA. They then worked on a similar CRISPR variant that aimed to override CRISPRoff. Named CRISPRon, this tool in effect flips the genes back on – a substantial breakthrough in the field.

An Eerie Poisonous Fog

If you’re visiting a farm, keep an eye out for an ominous-looking bronze fog. Nitrogen tetroxide, a red-orange gas, is made by certain bacteria during fermentation when oxygen is lacking in the crop. The lack of oxygen causes the bacteria to use the nitrate within the crops, which then produces nitrogen tetroxide. Inhalation of the gas is known to cause permanent lung damage or kill people and livestock. To prevent this, farmers have started performing¬†nitrate tests after four weeks of fermentation.

Happiness Is Two Scales

It’s put forth that happiness and unhappiness should be viewed as two different ‘scales’, not either end of one scale. For instance, if you’re not satisfied with your life, try to identify the root problem: do you not have enough happiness, or are you just unhappy?
