## Resource

Here is the audio edition of today’s post, about the American chestnut, a majestic tree that once dominated many forests in the eastern U.S. - but then an invasive fungal disease wiped out most of them in the last century. Listen about how researchers are using DNA to drastically speed up efforts to breed a resistant strain, with the ultimate goal of restoring these trees to their former glory.
