Bingo! 一查,确实是来自Nature! 请点 http://www.nature.com/news/2001/010628/full/010628-11.html 27 June 2001 Xavier Bosch Fungus eats CD Spores bore holes in compact disks, rendering them useless. Computers get viruses. Code gets bugs. Now CDs get fungus. Researchers in Spain have discovered a fungus that eats holes in compact discs, corrupting the information stored in them. After visiting Belize in Central America, Victor Cardenes of Madrid's National Museum of Natural Sciences (MNCN), found one of his CDs discoloured, transparent and unreadable. 2001年6月27日 夏佛‧柏士 霉菌吃CD : 胞子染上身,CD倒大"霉" 电脑感染病毒,程式跑出臭虫,这回,则轮到CD被霉菌搞上了. 西班牙的研究人员 发现霉菌在CD啃出洞来,破坏其中储存的资讯. 在访问中美洲国家贝里斯後,来自马德里国家自然科学博物馆的维克多‧卡登尼斯 发现他有张CD出现褪色,变透明且无法读取的现象. The disk's aluminium and polycarbonate layers were riddled with fungus, Cardenes and his colleagues have discovered. The team has isolated and cultured what they believe to be Geotrichum candidum. Usually, this fungus lives on plants and animals. Occasionally it infects the human respiratory tract. DNA analysis is pending. Burrowing in like worms from the side of the disk, "the fungus destroyed crucial information pits", says team-member Javier Garcia-Guinea. Pits in a CD's aluminium and polycarbonate sandwich store binary data, which is read by a laser. 卡登尼斯和他的同僚发现该碟片的铝和聚碳酸酯树脂塑胶层布满了霉菌,经过隔离 培养後他们确信那些是Geotrichum candidum(白色地丝菌). 这些霉菌通常生活在 动植物上,偶尔也会感染人类呼吸道. 惟DNA分析仍未确立. "那些霉菌像虫一样把CD的资料面当成他的窝,破坏了重要的资讯槽(pits)",研究 团队的一员,亚佛‧贾西-朱尼亚说. CD的铝-聚碳酸酯树脂夹层结构中的资讯槽,储存了 用雷射光读取的二进位资料. Some fungi are known to live on plastics and polymers, but this is the first report of a CD being eaten by a fungus. The researchers believe that the spores probably entered the CD in Belize. The rarity of this phenomenon suggests that Belize's high temperatures and tropical humidity were crucial. To find out more, the Spanish group has posted an offer on the internet to analyse unreadable CDs from anyone want- ing to test their disks for fungal infection. They have also submitted their work to the journal NaturWissenschaften. The problem with fungi is that we know far less about them than about bacteria, explains environmental microbiologist Marc Valls of Madrid's National Center. The finding that one has a taste for CDs is "not very surprising" he says, but it offers hope that fungi with similarly unusual proclivities might be exploited for environmental clean-up. 有某些霉菌是已知会生长在塑胶或聚合物上,但这是头一遭发现CD也会成为他的 大餐. 研究人员相信那些胞子是CD还在贝里斯时进驻其上的. 这罕见的现象让人联想到贝里斯的高温和热带潮湿气候可能是关键因素. 为找出 更多解答,该西班牙团队在网路上公开徵求受试者,帮他们测试手边那些无法读取的CD 是否遭到霉菌感染. 他们同时把工作成果交到期刊NaturWissenschaften的手上. 来自国家生技中心的环境微生物学家马克‧瓦尔斯解释道 "问题是,我们对霉菌的所知一向远低於细菌" "发现有霉菌对CD感兴趣并不让人太过惊讶" 他表示,有类似怪异倾向的霉菌,或许还提供了作为环保用途的一种可能. 原文附上两张图 The pits: fungal attack wipes CD data. http://www.nature.com/news/2001/010628/images/cd_160.jpg Grooving: fungus spores bore through a CD. http://www.nature.com/news/2001/010628/images/fungus_160.jpg =========================================================================== 归纳起来,事情的脉络可能是这样的. 地质学家Victor Cardenes在贝里斯发现CD有问题, 回国後他用显微镜先看过,觉得是霉菌在作怪,过程中Nature首先将此事披露,各家媒体 (如上述BBC等)皆引用於此并做延伸报导(至於中间穿插了哪些东西,最後再做整理). 而研究的成果,其实是投在NaturWissenschaften(注)这本期刊上. 注: NaturWissenschaften即是德文的Natural sciences =========================================================================== 待续..... --
