Bees follow linear landmarks to find their way home, just like the first pilots frontiersin
, before the invention of the first radio beacons and ground-based electronic systems, and modern GPS, pilots commonly navigated by following roads and railways—striking linear landscape elements at ground level that guide towards a destination of interest.. A century of research has shown that honeybees are navigators par excellence.
starting in a new, unexplored area. Linear landscape elements, such as water channels, roads, and field edges, appear to be important components of this navigation memory."In late summer of 2010 and 2011 near the village of Klein Lüben in Brandenburg, Menzel and colleagues caught 50 experienced forager honeybees and glued a 10.5-mg transponder on their back. They then released them in a new test area, too distant to be familiar to the bees.
The researchers had collected foragers from five hives: the home area around hives A and B resembled the test area in terms of the number, width, length, and angle of linear landscape elements, especially irrigation channels. The home range around hives D and E was highly dissimilar in this regard, while the home area around hive C was intermediate in similarity to the test area.

Claims about offshore wind farms killing whales are unsubstantiated, scientists saySince December, more than 23 whales have washed up dead along the east coast of the United States, leading wind energy skeptics to lay blame on the pending installation of offshore wind projects. But some scientists with the federal government say that there is no evidence to support those claims.
