DNA screening shows the beetle-resistant trees all share a similar genetic "fingerprint," said Janice Cooke, a University of Alberta biological sciences professor leading a genomics research project.

While there is controversy over genetic engineering, some scientists say it could also help fight climate change by creating trees that grow bigger, faster, resist disease and can even turn carbon ...

UBC researchers scraped bark and collected needles from 20 of these trees last summer, sending the samples to a lab for DNA sequencing. Results, published recently in Evolution Letters, showed that a ...
