英國一位六十九歲的老奶奶,因為證明蝸牛會認路回家,
獲得英國「最優秀業餘科學家」的榮譽。
香港太陽報報導說,這位叫「布魯克絲」的老奶奶,
因為家中菜園經常被蝸牛騷擾,
她高度懷疑常常光顧她家菜園的是同一批蝸牛,
因此開始每天注意;她的方法是:請鄰居幫助收集蝸牛,
然後她家的蝸牛和鄰居家的蝸牛,塗上不同顏色指甲油之後,
再將蝸牛交換,結果她發現,大部分的蝸牛,
都會回到原本出現的地方,最遠可以達到三十公尺。
老奶奶還發現,只要把蝸牛帶到超過一百公尺以外的地方,
蝸牛就會找不到路了。

A grandmother in Devon has made a startling discovery
about snails - it looks like they've got a built-in sat-nav
to find their way home!
Ruth Brooks has been named Britain's best amateur scientist
after coming up with an experiment to prove her theory.
She used nail varnish to mark a few garden snails,
so she could recognise them, then moved them from her garden.
Scientists thought the snails were too simple
to find their way home, but the painted molluscs had soon returned.
Mrs Brooks found the snails would keep coming back
if they were moved to within 30m of their starting point.
So if any of you have been growing your own veg
and want to stop snails chomping on the leaves,
she suggested moving the snails far further away.
"I would say that on the evidence that
it would be safe to take your snails away
beyond 100m or further and put them somewhere nice
with some food and you can be almost certain that they won't come back.
"I shall certainly be following that advice."
