Convection as a research area investigates buoyancy-driven and forced fluid motion arising from temperature or composition gradients, focusing on the coupled transport of momentum, heat, and mass in gases, liquids, and multiphase systems. It encompasses theoretical, numerical, and experimental studies of stability, transition to turbulence, pattern formation, and scaling laws in configurations such as Rayleigh–Bénard, thermal plumes, and mixed convection in boundary layers and porous media. This field underpins advances in geophysics, astrophysics, atmospheric and oceanic sciences, and engineering systems, where accurately resolving convective processes is essential for predictive modeling, control, and optimization of transport phenomena.
Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at extremely cold temperatures. The technology could be used to create phonon lasers, with possible applications ...

With a new lab-based experiment, researchers in the UK and France have recreated the characteristic cascades of energy and angular momentum that underpin key features of Earth's atmosphere. Reporting in Physical Review Letters, ...
Three years ago, in the waters of the Mediterranean Sea, the passage of an "ultra-energetic" cosmic neutrino was observed—the most energetic ever detected. The event drew international attention from the scientific community ...

To stay in the air when hovering over a flower, bumble bees continually flap their wings rapidly, a metabolic process that generates a massive amount of internal heat. Their flight muscles work so intensely that they can ...
When improperly folded proteins build up in the endoplasmic reticulum (ER), cells become stressed and conditions such as type 2 diabetes, neurodegenerative disorders, and cancers can develop. In a recent study published in ...
