Scientific Americans podcast節目還有60 sec earth； 60 sec psych； 以及30分鐘的訪談，是很好的聽力材料，最近在VeryCD上也比較火，本人在練聽力的同時順便制作了每期的lrc字幕文件，希望能為廣大英語學習者帶來方便，因為是自己制作的字幕，時間軸難免會有誤差，請大家見諒。
本人小水管作源，周六全天在線，基本上每周更新，不打算制作以前的podcast內容。
更改發布規則，不再單獨發布lrc和mp3文件，只發布wma音頻、字幕和解釋。

Sometimes scientific discoveries are hidden in museum specimen drawers and old journal articles. In two studies in the journal Science, researchers who went through the stuff in institutional attics offer new insights into the development and diversity of filter-feeding whales—and the fish that first occupied that ecological niche.
It had been thought that mammoth, filter-feeding fish—which swam through the water with a gaping, open mouth, collecting tiny marine creatures—only lived fleetingly before whales took their place in the food chain.
But a research team [led by Matt Friedman, University of Oxford] decided to take a closer look at museum fossils of bony, pre-historic fish that had either been misclassified or ignored. They also reexamined previous studies.The investigators now say that these fish filter-feeders lived from about 170 to 65 million years ago, a healthy stretch in which to pioneer and perfect the niche.

In a related study, scientists [Felix Marx, University of Otago, New Zealand and Mark Uhen, George Mason University] show that when filter-feeding whales took over from bony fish, their diversity was linked to the diversity of their dinner—the tiny creatures at the very bottom of the food chain –tiny algae known as diatoms.

[00:07.00]Sometimes scientific discoveries are hidden in museum specimen drawers and old journal articles.
[00:12.00]In two studies in the journal Science, researchers who went through the stuff in institutional attics
[00:17.00]offer new insights into the development and diversity of filter-feeding whales—
[00:20.00]and the fish that first occupied that ecological niche.
[00:23.00]It had been thought that mammoth, filter-feeding fish—
[00:26.00]which swam through the water with a gaping, open mouth, collecting tiny marine creatures—
[00:30.00]only lived fleetingly before whales took their place in the food chain.
[00:33.00]But a research team (led by Matt Friedman, University of Oxford)
[00:34.00]decided to take a closer look at museum fossils of bony, pre-historic fish
[00:38.00]that had either been misclassified or ignored. They also reexamined previous studies.
[00:42.00]The investigators now say that these fish filter-feeders lived from about 170 to 65 million years ago,
[00:48.00]a healthy stretch in which to pioneer and perfect the niche. (See http://bit.ly/9MVd4Y)
[00:52.00]In a related study, scientists
[00:52.60](Felix Marx, University of Otago, New Zealand and Mark Uhen, George Mason University)
[00:53.00]show that when filter-feeding whales took over from bony fish,
[00:56.00]their diversity was linked to the diversity of their dinner—
[00:59.00]the tiny creatures at the very bottom of the food chain

LRC文件

有時科學新發現就藏身在博物館的標本抽屜和就期刊裡。在科學雜志的兩項研究中，科學家在回顧舊歷的時候找到了須鯨分類和進化的新靈感，和最早充當該職位的魚類。
科學界一直認為，這種依靠口部的裂隙來濾食微生物的巨大魚類僅僅短暫的存在就被鯨魚所取代。
但一個研究團隊決定仔細查看博物館中的史前多骨魚類化石並發現這些化石不是被錯誤的歸類就是被忽略了。他們也重新檢驗了以往的研究。調查者說這些濾食性魚類生活在距今1億7千萬年至6千萬年間，是非常適合於食物鏈的這個位置的。
在一個相關研究中，科學家表示當須鯨取代多骨魚時，它們的多樣性與它們的食物 -- 一種食物鏈底層的稱作Diatom的藻類 -- 的多樣性是相關的。
這就是對於地球上最大動物和最小動物的新理解。
如有錯誤，歡迎大家批評指正！
institutional attics: 這個不會翻譯，估計應該是類似於象牙塔類的比喻吧
簡單譯文
補充：這兩天看了一下walking with the dinosaurs sea monsters與恐龍同行，海中巨獸的第三集，剛好看到了貌似這種魚的生物，就在這集中第二危險的海域，可以看到一種20 ~ 30長的巨大甲骨魚，馬文還一起和它們同游，不過周圍都是鲨魚、海中鳄魚什麼的。
