This is the time of year we are all itchy to watch the migrants moving through wherever it is we live. How these little dynamos do it has been a question that still doesn't have a complete answer.
A report in New Scientist describes a paper that sheds a new piece of information on part of the answer. This is a very important paper and should lead to a whole new study of migration from a molecular level.
On a more personal level this may lead to me understanding why my spouse is so bad at understanding directions....
...just kidding dear!
