How waves and mixing drive coastal upwelling systems
They are among the most productive and biodiverse areas of the world's oceans: coastal upwelling regions along the eastern boundaries of the Atlantic and Pacific Oceans. There, equatorward winds cause near-surface water to move away from the coast. T.....»»
Tracing the history of perturbative expansion in quantum field theory
Perturbative expansion is a valuable mathematical technique which is widely used to break down descriptions of complex quantum systems into simpler, more manageable parts. Perhaps most importantly, it has enabled the development of quantum field theo.....»»
Scientists demonstrate the survival of quantum coherence in a chemical reaction involving ultracold molecules
If you zoom in on a chemical reaction to the quantum level, you'll notice that particles behave like waves that can ripple and collide. Scientists have long sought to understand quantum coherence, the ability of particles to maintain phase relationsh.....»»
Researchers develop a detector for continuously monitoring toxic gases
Most systems used to detect toxic gases in industrial or domestic settings can be used only once, or at best a few times. Now, researchers at MIT have developed a detector that could provide continuous monitoring for the presence of these gases, at l.....»»
Mystery CRISPR unlocked: A new ally against antibiotic resistance?
CRISPR-Cas systems have revolutionized biotechnology by offering ways to edit genes like a pair of programmable scissors. In nature, bacteria use these systems to fight off deadly viruses. A recent international collaboration led by the University of.....»»
