Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

All of the conservation-related, science-based elements of the Forest Service are to be terminated or cut to the bone, while remaining functions to be centralized and narrowly focused on one goal -- timber production. This is an irreversible national disaster in the making.

After initially delaying their letter due to fears of retaliation, NSF workers have gone ahead anyway, and joined their colleagues at NIH, EPA, and NASA in speaking up.
