Insects Invented Gears Long before Humans Did
昆蟲發(fā)明齒輪裝置比人類早多了。
Planthoppers are tiny insects, only a couple of millimeters long. But man can they jump. An adult planthopper can sweep its two hindlegs together to spring forward more than a meter—the equivalent of you or I leaping over tall buildings in a single bound.
稻飛虱是只有幾毫米長的昆蟲。但是它們跳的跟人類一樣高。成年稻飛虱迅速移動兩條后腿向前彈跳一米多的距離,相當(dāng)于人類跨越一次越過高樓的距離。
But these superjumpers must push off with both legs at almost exactly the same time, or else they’ll go into a spin and wipe out.
但是這些跳高強(qiáng)手必須兩腿準(zhǔn)確同時發(fā)力,不然它們會快速旋轉(zhuǎn),跌倒在地。
A new study reports that the planthopper Issus coleoptratus evolved a foolproof solution to this problem: in young nymphs of the species, the two legs meet under the belly in plates fringed with interlocking teeth. They function just like mechanical gears. The work appears in the journal Science.
一項新的研究報告顯示稻飛虱進(jìn)化出一個萬無一失的解決方案:它們在幼年時期,它們的兩條腿在肚子下方被有緊連著的牙齒的鱗甲連接。它們的功能就像機(jī)械齒輪。這項研究刊登在《科學(xué)》雜志上。
As the bug cocks its two hindlegs forward and then thrusts them back to push off, those gears guarantee that both limbs complete their motions within 30 millionths of a second of each other.
當(dāng)?shù)撅w虱迅速移動后退前進(jìn)然后猛地往回推的時候,那些齒輪保證兩條腿百萬分之30秒的誤差內(nèi)完成動作。
The synchronized forces propel the nymph straight through the air at up to nine miles an hour—impressive. But adult planthoppers can jump at more than 12 miles an hour. And they do it using smooth-rimmed hips, with only friction to keep their legs in sync.
同步的動力能使得稻飛虱以九英里每小時的速度前進(jìn),令人印象深刻。但是成年的稻飛虱每小時跳行12英里。而且它們用光滑的臀部提供動力,只需要摩擦力保持它們的腿同步運(yùn)行。
So perhaps the gears are like training wheels, just there until the youngsters learn how to jump straight.
因此,或許這些齒輪就像經(jīng)過訓(xùn)練的輪子一樣,直到幼蟲學(xué)會如何跳直。 ?

There are about 900,000 known insect species,three times as many as all other animal species together,and thousands of new ones are described each year.They are commonly grouped in 27 to 32 orders,depending upon the classification used.The largest order is that of the beetles (Coleoptera).Next,in order of size,are the moths and butterflies (Lepidoptera); the wasps,ants,and bees (Hymenoptera); and the flies and mosquitoes (Diptera).Other major orders are the true bugs (Hemiptera); the cicadas,aphids,and scale insects (Homoptera); the grasshoppers and crickets (Orthoptera); the cockroaches (Blattodea); and the mantids (Mantodea). ?

我最喜歡的昆蟲
我最喜歡的昆蟲是知了.知了有兩個名字,又叫知了又叫蟬.知了是夏天常見的小動物,它有六只腳,前腳是彎彎的大刀,可以當(dāng)作它的武器,它的每一只腳上有一個勾子.知了的翅膀像有裂縫的玻璃.知了小時候是在地下的,長大的時候才鉆出來,聽說它的殼還能做藥呢!知了的食物是樹枝里的汁,只要嘴巴上的那根管插上去,就能痛痛快地吸汁了.知了爸爸的肚子下面有一個能叫的“馬達(dá)”,只要一摁就可以叫起來,它的聲音很響亮,三十米外都能聽得很清楚.
我常常和小朋友去抓知了,我們來到大樹底下,看見樹上有很多知了.有一次,刮風(fēng)的時候有一只知了飛下來,被我抓住了.我把它放進(jìn)一個大瓶蓋里,然后放進(jìn)裝滿水的盆里,它就爬到水里去了.我心里想:可能它想喝水吧.沒想到它是下去游泳的,它還會潛水呢!它在水里拍拍小翅膀,再潛到水里,它在水里叫,水里冒出很多泡泡.我把它從水里拿出來,它就不叫了.當(dāng)我把它放在地上,它像陀螺一樣的轉(zhuǎn)動,翅膀張開了,就快樂地唱起歌來. ?

A parasitic infection called Chagas Disease has similarities to the early spread of HIV, according to research published recently in the journal PLoS Neglected Tropical Diseases.
根據(jù)《PLoS被忽視的熱帶疾病》期刊近日發(fā)布的研究稱,一種名為“查加斯病”的寄生蟲傳染疾病和艾滋病早期的傳播過程具有相似性。
Like AIDS, Chagas is hard to detect and has a longincubation period before symptoms emerge, the study said, according to the New York Times.
根據(jù)《紐約時報》,該研究稱,查加斯病就像艾滋病一樣[難以覺察,而且在出現(xiàn)癥狀前有一段長時間的潛伏期。
As many as 8 million people are infected in the Western Hemisphere, mainly in Bolivia, Mexico, Colombia and Central America, as well as some 30,000 people in the US, the newspaper reported. Chagas infects people in areas of poverty, and most US cases are found in immigrants.
據(jù)《紐約時報》的報道,在西半球已有800萬人感染了這一疾病,患病者主要分布在玻利維亞、墨西哥、哥倫比亞和美洲中部,在美國也有3萬人感染此病。查加斯病在貧民區(qū)的人群中間傳染,許多美國患者都是外來移民。
Because Chagas is often left untreated, it spreads easily, either genetically or through blood transfusion. If caught early, it can be treated with intense medication, but the drugs are scarce in poor countries and very little money is invested in searching for new treatments, the paper said.
據(jù)報紙的報道,因為查加斯病常常得不到治療,因此它很容易就通過遺傳或輸血散播開來。如果在疾病早期發(fā)現(xiàn),可采用密集藥物治療方法,但窮國的藥品很稀缺,在尋求新療法上投資也很少。
Chagas is usually transmitted from the bite of blood-sucking insects thatreleasea parasite called Trypanosoma cruzi into the victim’s bloodstream. The parasite can eventually make its way to the heart, where it can live and multiply.
查加斯病通常是通過吸血昆蟲的叮咬、將被稱為克氏錐蟲的寄生蟲輸入受害者血液中進(jìn)行傳播。這種寄生蟲*會到達(dá)心臟,在那里生存和繁殖。
Infections often stay dormant for years, and then emerge as heart arrhythmias and heart failure. About a quarter of victims develop enlarged heart or intestines that can lead to sudden death if they burst, according to the Centers for Disease Control and Prevention.
根據(jù)美國疾病控制與預(yù)防中心,這種傳染病通常會潛伏數(shù)年,然后以心律失常和心臟衰竭的形式發(fā)作。約有四分之一的受害者會發(fā)展成心臟或腸道擴(kuò)大,如果發(fā)作可能導(dǎo)致猝死。
New research suggests Chagas may have led to the death of Charles Darwin — one of the great medical mysteries.
新研究顯示,查加斯病可能是查爾斯?達(dá)爾文的死因——達(dá)爾文的死是史上一個醫(yī)學(xué)之謎。
Researchers from the University of Maryland School of Medicine believe Darwin suffered from three different illnesses, including a Chagas infection contracted on a voyage to the Andes in South America, the Wall Street Journal reported earlier this month.
根據(jù)《華爾街日報》本月早些時候的報道,馬里蘭*醫(yī)的研究人員認(rèn)為,達(dá)爾文死前患有三種不同的疾病,包括去往南美安第斯山脈航海旅途中染上的查加斯病。
Darwin wrote in his diary that he was bitten by a “great wingless black bug” during the trip in 1835. He died 47 years later of heart failure.
達(dá)爾文在他的日記中寫道,1835年他在旅途中被一只“巨大的沒有翅膀的黑色昆蟲”咬了。47年后他因為心臟衰竭而死。 ?

Insects Will Be Part of UK Diet
2020年昆蟲將成為主食
Western diners should get used to the idea of eating insects because by 2020 it is "inevitable"they will form an important part of our diet,according to the entomologist who heads up the world's first university centre focusing on insects as a food source.
一位昆蟲學(xué)家指出,西方人應(yīng)當(dāng)適應(yīng)吃昆蟲的想法,因為到2020年昆蟲將不可避免地成為我們?nèi)粘o嬍车闹匾糠?。該昆蟲學(xué)家是全球關(guān)注昆蟲作為一種食物資源的*研究中心的負(fù)責(zé)人。
He argues that consumers who have traditionally turned their noses up at six-legged food may have to change their minds as conventional meat becomes more expensive and scarce.
他指出,隨著傳統(tǒng)肉類食物變得越來越昂貴和稀有,那些一向?qū)α鶙l腿食物嗤之以鼻的人可能不得不轉(zhuǎn)變自己的觀念。
Prof Marcel Dicke of Wageningen University said:"The most important thing is getting people prepared,getting used to the idea.
瓦格寧根*的馬塞爾?迪克教授說:現(xiàn)在最為重要的事是讓人們做好準(zhǔn)備,習(xí)慣這一想法。
Because from 2020 onwards,there won't be much of a choice for us."
因為從2020年以后,我們就沒有太多的選擇余地。
He wants to persuade people to ditch prejudices about insects,and to persuade manufacturers and suppliers to come up with products that can be sold in "a reassuring and attractive manner".
他想說服人民拋棄對昆蟲的偏見,并想說服生產(chǎn)商和供應(yīng)商將昆蟲食品以令人放心和吸引人的方式出售。
For centuries insects have been part of the daily diet of humans throughout the world,from the ants and larvae eaten as part of their subsistence diet by the tribes of Africa and Australia to the popular crispy-fried locusts and beetles enjoyed in Thailand.
很多世紀(jì)以來,在世界范圍內(nèi)昆蟲已經(jīng)成為人類日常飲食的一部分,其中包括被非洲和澳洲的原始部落示威生存必需品的螞蟻和蛹,以及在泰國大受歡迎的酥炸蝗蟲和甲蟲。
Insects as food are increasingly being promoted as an alternative which are more healthy,nutritious and sustainable than mainstream staples such as chicken, beef and fish.
昆蟲正越來越多地被推崇為一種比雞肉,牛肉和魚肉等主流食物更健康,更有營養(yǎng)和更具可持續(xù)性的新選擇。
As well as being low in cholesterol and high in protein,insects produce less waste, Dicke points out,as we typically throw away three-quarters of a chicken,but can eat the same percentage of a locust.
迪克指出,昆蟲屬于低膽固醇和高蛋白的食物,且造成的浪費(fèi)更少。我們在吃雞的時候,通常要扔掉其中的四分之三,而一只蝗蟲,我們則能吃掉它的四分之三。
Insects also win on the "conversion factor" or ration of feed ingested by the animal to the meat produced by it-known as ECI.
昆蟲同樣在轉(zhuǎn)換系數(shù)上領(lǐng)先。
Beef cattle has an ECI rate of 10 while the cockroach triumphs with 44.
牛肉的ECI比率為10,蟑螂遠(yuǎn)遠(yuǎn)高于此數(shù),為44。
The carbon emissions associated with growing insects is also far lower than those linked to conventional livestock.
昆蟲生長過程中的碳排放量也比傳統(tǒng)的牲畜要低得多。
