Strange Forest ‘Superorganism’ Is Keeping a New Zealand Vampire Tree Alive
The Grim Reefer shares a report from Live Science: Once a mighty kauri tree — a species of conifer that can grow up to 165 feet (50 meters) tall — the low, leafless stump looks like it should be long dead. But, as a new study published today in the journal iScience reminds us, looks are only surface-deep. Below the soil,…

Why do birds sing?
Birds spend a lot of time and energy singing, but they don’t do it the same way in every season of the year. And some can’t sing at all. What’s the purpose of birdsong? Source: https://earthsky.org/earth/why-do-birds-sing…
Many Animals Can’t Adapt Fast Enough To Climate Change
A new paper in Nature Communications, coauthored by more than 60 researchers, sifted through 10,000 previous studies and found that the climatic chaos we’ve sowed may just be too intense for many animals to survive. From a report: Some species seem to be adapting, yes, but they aren’t doing so fast enough. That spells, in a word, doom. To determine how…
Modeling exoplanet atmospheres
All atoms and molecules emit distinctive spectral lines across the spectrum, the details of which depend on the internal structures of the species (for example, the vibration and rotation properties of molecules) and how they are excited by their environments. Measurements of the features’ brightnesses, relative intensities, and shapes enable astronomers, at least in principle, to reconstruct most of the essential…
