Migrating seabirds face a surprising problem: jet lag

Oxford study shows Manx shearwaters get lost when their body clocks get out of sync Seabirds returning from foraging trips can be thrown hundreds of miles off course by a form of jet lag that arises when their body clocks get out of sync with local time, researchers say. Tracking data from Manx shearwaters on the west coast of the UK revealed that when the birds returned home to their colonies after trips over the Atlantic, their rapid eastward flights disrupted their sense of time and navigation.

NASA discovers Jupiter’s invisible shield is more complex than Earth’s

NASA’s Juno spacecraft has discovered that Jupiter uses a surprisingly complex system of powerful plasma waves and multiple shock regions to defend against the solar wind. The findings reveal major differences between Jupiter and Earth and could help scientists understand the enormous shock waves produced by exploding stars.
