Birds evolved compass 'head up display'

(PhysOrg.com) -- Certain birds may have compass information mapped directly onto their vision, much as fighter pilots have ‘head up displays’ overlaying flight information on their view of the skies.

Microscopic gyroscopes, the key for motion sensing

(PhysOrg.com) -- Tiny devices made possible by combining the latest advances in mechanical and electronics technology could be at the heart of next-generation personal navigation and vehicle stabilisation tools thanks to ...

Migratory birds eye-localized magnetoreception for navigation

Migratory birds use a magnetic compass in their eye for navigation. The involved sensory mechanisms have long remained elusive, but now, researchers have revealed exactly where in the eye avian navigation is situated.

Even non-migratory birds use a magnetic compass

Not only migratory birds use a built-in magnetic compass to navigate correctly. A new study from Lund University in Sweden shows that non-migratory birds also are able to use a built-in compass to orient themselves using ...

News about the light-dependent magnetic compass of birds

Birds have a light-dependent compass in their eyes. This compass gives them information about the direction of the Earth's magnetic field. Prof. Roswitha Wiltschko's research group at Goethe University Frankfurt, together ...

2012: Magnetic pole reversal happens all the (geologic) time

Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north with a magnetic compass in ...
