Mercury could have an 11-mile underground layer of diamonds, researchers say.

From CNN: "The diamonds might have formed soon after Mercury itself coalesced into a planet about 4.5 billion years ago from a swirling cloud of dust and gas, in the crucible of a high-pressure, high-temperature environment."

Trees don’t like to breathe wildfire smoke, either – and they’ll hold their breath to avoid it.

From @TheConversationUS: "In a study that started quite by accident when smoke overwhelmed our research site in Colorado, we were able to watch in real time how the leaves of living pine trees responded."

The Galapagos Islands and many of their unique creatures are at risk from warming waters.

AP reports: "The 2021 collapse of Darwin’s Arch, named for the famed British naturalist behind the theory of evolution, came from natural erosion. But its demise underscored the fragility of a far-flung archipelago that’s coming under increased pressure both from climate change and invasive species."

Last year, scientists and students from the University of Buffalo traveled to Iceland’s Litli-Hrútur volcano to test out a brand-new device that measures the viscosity of lava. Their findings should help them gain better understanding of how fast lava flows. More from Live Science: https://flip.it/YWoAWy
