After his safe return to Earth, the Forest Service germinated the seeds and successfully planted “moon trees” throughout the 50 states along with one on the White House grounds.

Bats do not make it easy to study bats

Jane Hodgins, October 25, 2017 at 3:45pm

For decades, bats have defied scientists’ best ideas for keeping track of individuals, which is crucial to wildlife research. Banding (either legs or forearms) can result in injury, and banded bats are seldom recaptured anyway. Tattoos take too long. Holes punched in their wings are only visible for 5 months. Electronic tags have to be close to a reading device to work.
