The download: CRISPR crops and debunking renewable energy myths


This is today’s edition of The Download,our weekday newsletter that provides a daily dose of what’s happening in the tech world.

How CRISPR can help save crops from devastation caused by pests

For decades, California grape growers have battled Pierce’s disease, a nasty infection that causes vines to wither. The arrival of an invasive insect in the late 1980s boosted the spread of the disease, turning it from a nuisance to a nightmare.

The disease still has no cure and is at risk of worsening due to climate change. But an unlikely solution has emerged in the form of CRISPR gene-editing technology, which allows researchers to alter the pest’s genome so it can no longer spread the bacterium. Read the full story.
