Our simulations of forces, torques, power expenditure and flow fields show great consistency, with the aerodynamic features being entirely robust to the wide variety of body velocities and wing ...

Water waves can gain energy when they scatter from a whirlpool-like vortex. That is the conclusion of physicists in Brazil, Canada and the UK, who are the first to observe a phenomenon called ...

Beams of electromagnetic radiation can be used to detect the rotation of distant objects if they have orbital angular momentum – known as ‘vortex waves’. It involves exploiting a rotational form of ...

What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an ...
