Tell the Lorax we’re on the case

The emerald ash borer has destroyed tens of millions of ash trees in North America, but now British researchers have identified a gene in some ash trees that protects them.

DNA sequencing of more than 20 ash tree species from around the world has revealed over 50 “resistance genes”, which make chemicals harmful to insects.

Knowing the gene means a bit of old-fashioned genetic engineering — breeding the resistant trees with existing ones — could save and restore ash tree populations in the U.S., and protect those in Europe.
