How gophers brought Mount St. Helens back to life in one day
When Mount St. Helens erupted in 1980, lava incinerated anything living for miles around. As an experiment, scientists later dropped gophers onto parts of the scorched mountain for only 24 hours. The benefits from that single day were undeniable—and still visible 40 years later.

Researchers find dragonfly species with darker wings have evolved to withstand heat and attract partners
Dark wing ornaments cause additional heating of 1°C to 2°C, which roughly equals the increased thermal maxima of ornamented species. Of the species studied, the arch-tipped glider (Tauriphila argo), a tropical species with very dark wing color patches near their core body, could tolerate the highest temperatures.
