Various animals evolved coloration that keeps them hidden. A jaguar's patterns help it slink undetected across the sun-dappled rainforest floor. The mottled pigmentation on the wings of some let them rest on tree bark undisturbed. And then there are animals that can quickly change their appearance—for example, the Central Bearded Dragon.
很多動物進化自身的保護色。美洲豹的顏色可以讓它在太陽照射下斑駁的雨林地帶潛行。一些動物翅膀上的斑駁沉著色素可以讓動物們在樹上休息，同時不被打擾。同時，還有動物可以快速改變它們的外表，如鬃獅蜥。
This two-foot-long lizard lives in the more arid parts of Australia.
這兩英尺長蜥蜴生活在澳大利亞的乾旱地區。
"They can change color really quickly, just in a matter of seconds or minutes.”
它們可以非常迅速地改變自身的顏色，僅僅只需要數秒鐘或者數分鐘的時間。

“And they do this by moving pigments within specialized skin cells called chromatophores."
這些動物是通過轉移特定皮膚內細胞內的色素來實現的。
Bearded dragons modify their colors for camouflage, or to maintain their body temperature, or to communicate with other dragons. Smith wanted to know how they meet all those needs with the same tool kit.

🎁 中英文稿：
Last week, tens of thousands of gallons of sewage gushed into urban streams in Baltimore, because of leaky pipes and flooding rains. And when that happens, it's not just organic matter and microbes that get flushed into aquatic habitats. It's drug residues, too: caffeine, antihistamines, headache drugs... even amphetamines and heroin.
上周，由於管道洩露以及大量降水，成千上萬加侖的污水流入巴爾的摩的城市河流中。流入水中棲息地的，不僅有有機物質、微生物，同時還有殘留的藥物：咖啡因、抗組胺藥、頭痛藥……甚至還有安非他命以及海洛因。
Researchers actually detected all those drugs a few years ago, in a survey of urban and suburban streams in Baltimore. And they wanted to see what effect illegal drugs, like amphetamines, might have on aquatic ecosystems. So they built artificial streams in the lab, stocked with insects and real creek rocks—slippery ones with biofilms of algae and bacteria growing on them. Then they doped half the streams with amphetamine residues—similar to the concentrations found in real urban streams.
實際上，在幾年前，研究人員就測量的巴爾的摩河流中的那些藥品。他們調查的目的是想要瞭解一些非法藥物，如安非他命、對水生系統產生什麼樣的影響。所以，研究人員在實驗室建立了一個人工河流，河流裡面有昆蟲以及真的小溪岩石——光滑的岩石上面長有藻類和細菌。然後他們在一半的人工河流中投放了安非他命殘留物——這時其濃度與現實中的城市河流中的濃度相似。
After three weeks, the mix of microbial life in the amphetamine-laced streams changed significantly, compared to the untainted waters. And insects like midges emerged earlier than usual—suggesting that drug residues might be able to alter food webs underwater, and on land, too. The results appear in the journal Environmental Science and Technology.
三周之後，與未受污染的河流相比，加有安非他命的河流物種微生物發生了重大的變化。搖蚊等小昆蟲出現的時間縮短——這表明藥品殘留物可能會改變水中的食物網，以及陸地上的食物網。該研究結果發表在《環境科技》雜誌上。
Previous studies have shown that even treated sewage has lots of drug residues in it—because most wastewater treatment plants weren't built to filter out pharmaceuticals. One solution, the researchers say, is more up-to-date wastewater infrastructure. Think of it as preventive medicine…for the nation's aquatic life.
先前的研究表明：處理過的污水中也含有大量的藥物殘留——因為大多數的汙水處理廠並不是用於過濾藥物的。研究人員表示，一種解決方案就是更新汙水處理設備。就把這看作水生生物的預防藥吧。

Used to be, teenage kids had to carry around a bag of flour wrapped in a blanket to learn the responsibilities of parenthood. But these days? The same lesson is taught with hi-tech dolls that cry and record every interaction.
曾經，十幾歲的孩子必須隨身攜帶一袋麵粉裹著毯子學習為人父母的責任。但是，現在呢? 通過高科技娃娃以及記錄與娃娃的互動，孩子們也可以學到為人父母的責任。
"You know they get grumpy, you have to rock them to calm them down, they have to be fed." Sally Brinkman, an epidemiologist at the Telethon Kids Institute, in Australia. "It's supposed to be so tiring and so difficult that it puts them off and they say 'I don't want to be a teenage mom.' And then they think about contraception and all of those sorts of things."
小嬰兒脾氣暴躁，你必須要搖一搖他們，來讓他們安靜下來，來必須要喂他們食物。薩利•布林克曼是澳大利亞電視節目研究所的流行病學家。“照顧嬰兒的過程非常的枯燥無聊，孩子們最後都會說，我不想十幾歲就當媽媽。”然後他們就會想避孕以及其他所有的事情。
Problem is, that theory--that the dolls will discourage teenage parenthood—doesn't seem to be true, according to a new study by Brinkman and her colleagues. The team recruited nearly 3,000 13- to 15-year-old girls for the trial, from 57 schools in Western Australia. All the girls got the standard Australian curriculum on contraception and sexual health. But half had to care for the infant dolls—and got extra education sessions with the school nurse.
現在問題是，這一理論——娃娃會阻礙青少年發育——根據布林克曼和她同事們的說法，這是錯誤的。研究團隊從西澳洲的57所學校招募了約3000年13到15歲的女孩參與此次試驗。這些女孩都學習了避孕和性健康的課程。但是一半女孩必須照顧嬰兒——並跟隨學校護士學習額外的教育課程。
The team's hypothesis? "We thought either it's going to make a difference, or it's going to make no difference whatsoever. We hadn't expected that it would do the opposite." And in fact, the girls who cared for the dolls were nearly one and a half times more likely to get pregnant before age 20, than teens in the control group. The findings are in The Lancet.
該團隊的研究假設?“我們認為這會產生不同，或者根本不會造成任何區別。我們沒有想到最後的結果是完全相反。”實際上，需要照顧寶寶的女孩在20歲懷孕的概率是對照青年組的1.5倍。
The company that makes the dolls has criticized the trial, and says the researchers didn't properly implement the educational portion of the program. But Brinkman disagrees. Maybe, she says, the program itself is flawed. "If we're inadvertently increasing teenage pregnancy rates, you know, this program needs to stop. We shouldn't be delivering it in schools."
製作娃娃的公司批判了此次實驗，並表示研究人員沒有恰當地貫徹此部分的教育計畫。但是布林克曼對此持不同意見。她表示，或者是這個過程本身存在缺陷。如果我們無意間增加了青少年的懷孕幾率，那麼該專案需要停止。我們不應該在學校繼續進行。
