In a new study, a team of geologists and biologists led by CU Boulder resurrected ancient microbes that had been trapped in ice—in some cases for around 40,000 years. The study is a showcase for the planet’s permafrost. That’s the name for a frozen mix of soil, ice and rocks that underlies nearly a quarter of […]

The liquid will tell him if toothy finned predators swim in this body of water. Earlier this summer, more than 50 juvenile Chinook (king) salmon hovered […]
