Tea bags release microplastics
飲袋裝茶會喝入微塑料?
Every time you use a tea bag, you could be dosing yourself with billions ofmicroplasticandnanoplasticparticles. That's the conclusion of researchers at McGill University in Montreal. The research, published in the American Chemical Society journal Environmental Science & Technology, centered on four different types of plasticmeshtea bags, of the kind recently preferred by somepremiumbrands.
每次喝袋泡茶時,你可能喝進去的是數十億微塑料和納米塑料顆粒。這是蒙特婁的麥吉爾大學研究人員得出的結論。發表在美國化學學會期刊《環境科學與技術》上的這項研究聚焦於4種不同的塑料網眼茶袋,是一些優質品牌近來喜歡使用的那種茶袋。
Having been emptied of the tea itself, the bags were placed in water heated to 95 C. Researchers were surprised to find each bag released around 11.6 billion microplastics and a further 3.1 billion even smaller nanoplastics.
研究人員將茶袋裡的碎茶取出,將茶袋放入加熱至95攝氏度的水中。研究人員驚訝地發現,每個茶袋釋放出大約116億個微塑料和31億個更微小的納米塑料。
These levels were, says the report, "thousands of times higher than plastic loads previously reported in other foods". Scientists note that more research is needed to determine whether the plastics' effect on humans isnegligible,subtle- orchronic.
報告稱,這一水平"比先前報導過的其他食物塑料含量高出數千倍"。科學家指出,還需要進行更多研究才能確定微塑料對人類的影響是可以忽略的、微妙的還是長遠的。

Impact of background music
背景音樂會阻礙創造力
From Mozart to Metallica, tons of people enjoy listening to various types of music while they paint, write, or draw. Many believe music helps boost creativity, but an international study conducted by English and Swedish researchers is challenging that notion. Psychologists from Lancaster University, the University of Gavle, and the University of Central Lancashire say their findings indicate music actuallystymiescreativity.
從莫扎特到金屬樂隊,無數人在寫作或繪畫時喜歡聽各種音樂。許多人認為音樂有助於激發創造力,但一項由英國和瑞典研究人員進行的國際研究正在質疑這一觀點。蘭卡斯特大學、耶夫勒大學和中央蘭開夏大學的心理學家表示,他們的發現表明音樂實際上阻礙了創造力。
To come to their conclusions, researchers had participants complete verbal insight problems designed to inspire creativity while sitting in a quiet room, and then again while music played in the background. They found that background music "significantly impaired" the participants' ability to complete tasks associated with verbal creativity. It's worth mentioning that even familiar music with well-known lyrics impaired participants' creativity, regardless of whether or not iteliciteda positive reaction.
研究人員讓參與者在安靜的房間裡完成了一些旨在激發創造力的語言洞察問題,然後讓他們在播放背景音樂時再做一次,從而得出了這一結論。研究人員發現,背景音樂"顯著地削弱"了參與者完成與語言創造力有關的任務的能力。值得一提的是,即使是參與者熟知歌詞的音樂也會削弱其創造力,不管它是否引起了積極的反應。

Ozone hole strangely shaped
南極臭氧空洞'異乎尋常'
The ozone hole that opens every year over the Antarctic is on course to be the smallest in three decades, scientists have said. The hole is currently well under half the area that usually opens up by mid-September, and may have already reached its maximum size, a little smaller in area than the Antarctic continent.
科學家稱,南極上空每年出現的臭氧空洞將是30年來最小的。目前,臭氧空洞的面積小於通常情況下9月中旬面積的一半,而且可能已經達到最大尺寸,比南極大陸的面積還要小一點。
Researchers say the hole is also a particularly unusual shape this year, being heavilyskewedtowardSouth America instead of centering on the South Pole. The rare shape - never before observed - indicates a significant distortion to the usual polarvortex, which maintains low temperatures in thestratosphere.
研究人員說,今年臭氧空洞的形狀也特別不尋常,嚴重向南美洲傾斜,而不是以南極為中心。這一罕見的異常形狀表明,常見的極地漩渦發生巨大的扭曲。極渦維持著平流層的低溫。
Anna Jones, a scientist at the British Antarctic Survey, said: "Very occasionally in the Antarctic you will getdisturbances.And I don't think anybody knows what's triggered it this year. This is a pretty new phenomenon. It could be a multiple collection of factors."
英國南極調查局的科學家安娜•瓊斯說:"在南極,很少會受到幹擾。我想沒有人知道是什麼引發了這種改變。這是一種全新的現象,可能是多種因素造成的。"

Probiotic beer boosts health
新加坡研發益生菌啤酒
If you needed yet another reason to drink beer, science just gave it to you. Researchers from the National University of Singapore (NUS) developed a new type ofprobioticbeer which could improve your immune system andneutralizepathogensandtoxins. The idea came from Chan Mei Zhi Alcine, a fourth-year student from the Food Science and Technology Program at the NUS Faculty of Science.
如果你還需要一個喝啤酒的理由,科學已經給了你這個理由。新加坡國立大學的研究人員研發了一種新型的益生菌啤酒,這種啤酒可以改善你的免疫系統,消除病原體和毒素。這一靈感來源於新加坡國立大學理學院食品科學技術系大四學生陳美芝(音譯)。
She realized that while the marketabounds withdairy-based probiotics, there's another huge untapped market for probiotics: beer. Due to its nature, beer is afertileground for probiotics, and thecraft beerphenomenon has beengrowing at a staggering ratein many parts of the world - so why not blend the two?
她意識到,儘管市場中有多種以牛奶為原料的益生菌,但還有一塊巨大的益生菌市場尚未被開發——啤酒。由於性質使然,啤酒是益生菌的沃土,而且在世界上許多地區,精釀啤酒現象正以驚人速度增長。那麼,為何不將兩者合二為一呢?
