High-pressure setup unlocks detailed measurements of organized structures in turbulent flows
Turbulent flows are ubiquitous: they are found in clouds, in the ocean and even on other planets. Yet despite their chaotic nature, they also form large-scale structures that can be calculated and predicted. For example, while long streaks of clouds may appear orderly from the ou

Knowing how plants stretch out when warm could help dial back their response
When they start to get too warm but before they're dangerously hot, most plants employ a similar playbook. They change their shape, a host of adaptations that includes growing longer stems and stalks to promote air circulation.
