This is Scientific American 60 seconds Tech, I'm Larry Greenemeier, got a minute?
這里是科學美國人60秒科技頻道，我是拉里·格林梅耶。
O brave new world, that has electronic cigarettes in it.
在這個勇敢的新世界里，總有電子香煙的存在。
Earlier this year, the U.S. Food and Drug Administration said it wants to regulate electronic cigarettes.
今年年初，美國食品和藥物管理局決心治理電子香煙，
The agency has even promised to shell out $270 million to 48 research projects for study of the health risks of "vaping".
并計劃拿出2億七千萬美元給48個研究機構，用于研究電子香煙存在的安全隱患。
But this effort to get ahead of a possible public health problem might be pointless.
但是，要治理這個公眾健康問題，只靠這些努力作用是微乎其微的。
Because even if we learned the risks of tobacco-less e-cigs, some users are modifying these devices to produce stronger flavors, more impressive vapor clouds and to deliver even more nicotine.
原因在于，即便人們知道了無煙草的電子香煙確實存在安全問題，一些使用者還是對電子香煙進行改進，這些香煙與普通香煙相比氣味更重，煙霧更多，甚至釋放出更多的尼古丁。
Virginia Commonwealth University is using part of their $18.1-million share of the FDA's money to study this e-cigarette hacking.
弗吉尼亞聯邦大學作為48所指定研究機構，拿到了1810萬元的研究基金。
Of particular concern are modifications that make these devices burn hotter and supposedly produce a larger vapor cloud when exhaled.
研究顯示，在電子香煙的種種危害之中，最令人堪憂的就是點燃后過熱以及產生過量的煙霧。
E-cigarette fans proudly point out that these devices produce water vapor rather than smoke.
但電子香煙的愛好者卻引以為豪地宣稱電子煙產生的是水蒸汽而非煙霧。
Scientists, however, want to know what may be carried along with the water vapor—especially when vaping liquids are superheated, possibly emitting formaldehyde and other toxic components.
但科學家更想知道的是伴隨著水蒸氣釋放出來的其他氣體還有什么，比如液體過度加熱時可能會產生的甲醛等有毒氣體。
Why, it's enough to make you question one company's choice of renowned vaccine expert Jenny McCarthy to be their e-cigarette celebrity pitchwoman.
這些足夠讓你質疑公司令詹尼·麥卡錫擔任宣傳電子香煙的明星代言這一選擇了吧。
Thanks for the minute for the Scientific American 60 Seconds Tech, I'm Larry Greenemeier.
感謝收聽科學美國人60秒科技頻道。
