In Yellowstone, the wolves quickly reclaimed their spot as top predator. Ecologist William Ripple of Oregon State University has been studying the wolves since their return. He found that, within a decade of their release, the wolves had cut the number of elk – their main prey – by half. The surviving elks avoided the wolves’ core range and stayed on the periphery. Woody trees like aspen and willow, which had been chewed and trimmed by zealous elks, now grew tall and lush.

Children are not often invited to speak to the United Nations General Assembly. But there stood Felix Finkbeiner, German wunderkind in his Harry Potter spectacles, gray hoodie, and mop-top haircut—with a somber question about climate change. … “For most adults, it’s an academic question.

The man who rebuilt a village

Life for Maila and Dawa Jangbo Lama came to a crashing halt when a 7.8-magnitude earthquake rocked Nepal in April 2015. The couple scurried out in the nick of time, but their house, which was also their boutique travel lodge and grocery store, was damaged beyond repair.

A new study, published in the journal Nature, describes fossilized microorganisms thought to be between 3.77 and 4.28 billion years old. They were found in Quebec, Canada’s Nuvvuagittuq greenstone belt, which is home to some of Earth’s most ancient rocks. Inside, researchers found the fossils of what they say are long-gone bacteria left behind during Earth’s tumultuous early days.
