June 6, 2024 The molecules that make up the matter around us are in constant motion. What if we could harness that energy and put it to use? Over 150 years ago Maxwell theorized that if molecules' motion could be measured accurately, this information could be used to power an engine. Until recently this was a thought experiment, but technological breakthroughs have made it possible to build working ...

June 6, 2024 What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex 'soup' that is hard for scientists to decipher. Now, researchers have demonstrated a way to extract and identify these indicator compounds in ...

June 6, 2024 An acoustic transmitter -- or tag -- emits unique signals or 'pings' when scientists want to study the long-distance movement of marine animals. However, this method has limitations. Using a movement model, researchers reconstructed animal tracks and leveraged an iterative process to measure the accuracy and precision of these reconstructions from acoustic telemetry data. Results demonstrate how ...
