Peatlands Under Threat: A Huge Carbon Reservoir at Risk of Release
The Hidden Giant: Peatlands as a Global Carbon Reservoir Peatlands—wetland ecosystems saturated with partially decayed vegetation—contain an immense store of carbon. Across the globe, these spongy landscapes hold more carbon than all the world’s forests combined, a striking statistic that underscores their climate importance. But a growing body of research indicates that this carbon reserve…

Cryo-imaging Breakthrough Reveals Thick Biological Structures with Greater Clarity
Overview: A New Window into Thick Biological Samples Cryo-imaging has long promised a clearer view of biological materials in their near-native state. Traditional electron microscopy, while superb for isolated molecules, struggles with thicker samples. A Cornell-led team has unveiled a transformative method—tilt-corrected bright-field scanning transmission electron microscopy (tcBF-STEM)—that delivers higher contrast and dramatically increased efficiency…

Birds’ Vocal Warnings Point to Language Origins: Global Study
Birds’ Vocal Warnings Reveal a Global Link to Language Origins ITHACA, N.Y. – A remarkable cross-continental discovery shows that more than two dozen bird species, spread across four continents, share a nearly identical whining vocal warning. The sound is produced when a parasite bird—such as a cuckoo—intrudes on a nest, and the host birds identify…
