‘Insect-eye’ compass can navigate by the sun even on a cloudy day

Ant head with compound eyes

The eyes of insects like ants can detect the polarisation of light Razvan Cornel Constantin/Alamy A compass that relies on polarised light can use the sun to tell where magnetic north is, even when it is cloudy. It is based on how some insects navigate and could be used when conventional magnetic compasses aren’t reliable, … Read more

Wing-flapping robot helps explain the evolution of insect flight

Carolina Sphinx Moth (Manduca sexta)

The tobacco hawk moth (Manduca sexta) Jay Ondreicka/Shutterstock Some insects can flap their wings so rapidly that it’s impossible for instructions from their brains to entirely control the behaviour. Building tiny flapping robots has helped researchers shed light on how they evolved to do this. If you flap your arms, each movement happens after your … Read more

Animal motion-capture studio tracks bird flocks and insect swarms

Starlings perched in a motion-capture lab built inside a converted barn Christian Zeigler An animal behaviour lab built inside a converted barn uses motion-capture cameras to track the movements and behaviours of entire flocks of birds or swarms of insects. The so-called SMART-BARN resembles a Hollywood motion-capture studio with 30 infrared cameras capable of tracking … Read more

Robotic dog spots invasive fire ant nests better than humans

Robotic dogs can locate fire ant nests.

Robotic dogs can locate fire ant nests Xin Su | Lanzhou University Robotic dogs can spot invasive fire ant nests more efficiently than human searchers – and they can safely stir up a swarm of aggressive ants by poking their nests, which can help researchers identify the notorious pests. The red imported fire ant (Solenopsis … Read more
