How gene-edited microbiomes could improve our health
Microbes are everywhere, and the ones in our bodies appear to be incredibly important for our health. They’ve developed intricate relationships with other living systems, feeding on chemicals in their environments to produce other chemicals—some of which are more beneficial to nearby organisms than others.
Getting microbes to work for us has been a tantalizing prospect to scientists for decades. Can we tweak the genomes of these microbes to control exactly which chemicals they break down or produce, for example? What if we could get microbes to help us reduce pollution, or create microbes that make medicines?
The good news is that new technologies are bringing us ever closer to making engineering microbes to benefit our health and environment a reality. Experts say we could be as little as four years away from human treatments. Read the full story.

The big story
The great chip crisis threatens the promise of Moore’s Law
The world is facing an economically devastating shortage of microchips.
Production has also slowed for smartphones, laptops, video-game consoles, TVs, and even smart appliances, all because of the lack of cheap microchips. Their use is so essential and so widespread that some observers think the chip crisis could threaten the global economic recovery from the pandemic.
The spirit of Moore’s Law—the expectation that cheap, powerful chips will always be readily available—is now being threatened by something far more mundane: inflexible supply chains. Read the full story.
