Spectacular fossil treasure trove pushes back origins of complex animals

Ever wondered what it might feel like to spot giant spider crabs while you're snorkeling? Or check plants for the circular holes that indicate native bees are collecting nest materials? Citizen science relies on people like you—more than a million of them in Australia, actually—to collect and analyze valuable data about the world around us.

A surprising observation in the lab has revealed a remarkable ability in Stentor coeruleus, a single-celled organism about one millimeter long. Sometimes nicknamed the "platypus" of microorganisms for its trumpet-like shape, this tiny creature appears to have a distinct preference for corners.

Control of heat transport in nanostructures is of central importance for numerous modern technologies—from high-performance computer chips that need to be cooled to energy converters—and is a highly active area of research. While great progress has been made in recent years in understanding how heat transport can be influenced by nanostructuring, it was previously unclear whether the replacement of a single atom in a molecule could measurably alter phonon transport—i.e. heat transport through la

A United Nations-backed framework for protecting tropical forests could allow governments to collect income from carbon credits without advancing forest conservation. The weakness lies in how the program calculates baselines, which is the expected rate of deforestation without intervention. There is no evidence that enrolled jurisdictions—countries, states, and provinces—have acted on that opportunity, but the incentive structure favors those who do, according to a study by Yale researchers appe
