Examining the intricacies of ozone removal by deciduous forests

Ozone plays a vital role in Earth's climate system. In the stratosphere, which begins about six miles (9.7 kilometers) off the ground, ozone protects the planet from harmful ultraviolet radiation. Lower in the atmosphere, ...

Bat flight model can inspire smarter, nimbler drones

Bats are among nature's best flyers—able to fly for long periods of time, maneouvre in mid-air with pinpoint precision and get into some very tight spaces. However, scientists have not fully understood exactly how bats ...

Winging it: How do bats out-maneuver their prey?

Bats catch food 'on the wing' without touching the ground, but how do they do it? A new study by Per Henningsson at Lund University, Sweden is the first of its kind to analyse the aerodynamics of bats performing manoeuvers ...

An airflow model to reduce time on the tarmac

Plans for summer holidays are already taking shape. But before jetting off for some fun in the sun, many travellers will have to cope with long delays on the airport runway.

Langmuir circulation inhibits near-surface water turbulence

In the surface ocean, breaking waves are a major source of air bubbles and turbulent kinetic energy. During the presence of a consistent surface wind, these wave-generated bubbles, along with other surface material like seaweed ...
