科學(xué)家們?cè)诮o牛涂上斑馬條紋后感到很驚訝——它們被咬的幾率比平常少了50%

Every once in a while, researchers come up with the most outrageously ingenious ideas that prove once and for all that imagination is just as important as intelligence when it comes to science. These are the types of ideas you’d more often see in Lewis Carroll’s Alice’s Adventures in Wonderland than in real life. Or at least that’s what you’d expect.

每隔一段時(shí)間，研究人員就會(huì)想出最驚人的創(chuàng)意，一勞永逸地證明，在科學(xué)領(lǐng)域，想象力和智力一樣重要。這些是你在劉易斯·卡羅爾的《愛(ài)麗絲漫游仙境》中比在現(xiàn)實(shí)生活中更?？吹降挠^點(diǎn)?；蛘咧辽龠@是你所期望的。

Scientists conducted a study showing that there’s a far better way to protect cows from pesky biting flies than using pesticides. That method involves painting the cows with zebra-like stripes, which help camouflage the animals from annoying pests. Researchers tested their theories on 6 Japanese Black cows by either painting zebra-like stripes (black-and-white, see cow ‘a’), painting only black stripes (cow ‘b’) or leaving the dark fur unpainted (cow ‘c’). By liberally applying paint, scientists have effectively created a temporary zebra-cow hybrid (a zow or a cowbra if you’ll permit me) that lives a far happier life thanks to not being bitten countless times each day. The cows are happy. The farmers are happy. And the flies are miserable. It’s _mootastic_ all ‘round.

科學(xué)家進(jìn)行的一項(xiàng)研究表明，有一種比使用殺蟲(chóng)劑更好的方法來(lái)保護(hù)奶牛免受討厭的蒼蠅叮咬。這種方法包括在奶牛身上畫(huà)上類(lèi)似斑馬的條紋，這有助于保護(hù)奶牛免遭討厭的害蟲(chóng)傷害。研究人員在6頭日本黑奶牛身上測(cè)試了他們的理論，他們的測(cè)試方法是:要么畫(huà)斑馬狀的條紋(黑白相間，參見(jiàn)cow a)，要么只畫(huà)黑色的條紋(cow b)，要么不畫(huà)深色的皮毛(cow c)。通過(guò)大量的涂漆，科學(xué)家們已經(jīng)創(chuàng)造出了一種臨時(shí)的斑馬和奶牛的雜交品種(如果你允許的話，我可以把它叫做zow或者cowbra)，由于沒(méi)有每天被咬上無(wú)數(shù)次，它的生活要快樂(lè)得多。奶牛們很高興。農(nóng)民們很高興。蒼蠅很可憐。這是一個(gè)很有爭(zhēng)議的問(wèn)題。

Dear Pandas, after you’re done with this post, check out Bored Panda’s previous article about a baby zebra that was born with white spots instead of stripes. I’m sure you’ll love it.

親愛(ài)的熊貓們，當(dāng)你看完這篇文章后，去看看Bored Panda之前的一篇文章吧，這篇文章是關(guān)于一只出生時(shí)身上沒(méi)有條紋，只有白色斑點(diǎn)的小斑馬的。我相信你會(huì)喜歡的。

According to the Japanese researchers who conducted the striped-cow study, their findings are important because they show that pesticides are not as effective at keeping away pests as painting stripes on cows’ fur with non-toxic materials. It’s cheaper. It’s healthier. It’s environmentally friendly. What’s not to like?

Scientists recorded how often the moo-moos would repel biting flies and determined that zebra-stripes “significantly” lowered the number of pest attacks. Thus, we have available an alternate way of protecting our bovine buddies from aggressive flies that doesn’t require spraying everything in sight with pesticides.

科學(xué)家們記錄了mooo -moos驅(qū)趕蒼蠅的頻率，并得出結(jié)論，斑馬條紋“顯著”降低了害蟲(chóng)襲擊的次數(shù)。因此，我們有了另一種方法來(lái)保護(hù)我們的?；锇槊馐芄粜陨n蠅的侵害，而不需要在看到的任何東西上噴灑殺蟲(chóng)劑。

The study showed that zebra-like black-and-white stripes were significantly better at deterring flies than just black stripes or no stripes at all

研究表明，與只有黑色條紋或完全沒(méi)有條紋相比，類(lèi)似斑馬的黑白條紋能更好地阻止蒼蠅

There are several main theories about what black-and-white zebra stripes do. For example, some scientists believe that the stripes help zebras hide from flies and other pests, while others think that the stripes work as camouflage and help the animals remain unnoticed by some predators. However, a third theory is that the stripes are, in fact, a natural cooling system that helps zebras stay fresh in the searing African heat.

關(guān)于黑白斑馬條紋的作用，有幾種主要的理論。例如，一些科學(xué)家認(rèn)為條紋有助于斑馬躲避蒼蠅和其他害蟲(chóng)，而另一些人認(rèn)為條紋是一種偽裝，幫助動(dòng)物不被一些捕食者發(fā)現(xiàn)。然而，第三種理論認(rèn)為，事實(shí)上，條紋是一種自然冷卻系統(tǒng)，幫助斑馬在非洲炎熱的天氣中保持新鮮。
