  • First artificial life form 創造生命

    科學家已把無生命的化學物質轉化為有生命的有機體,這項實驗對生命的本質提出了意義深遠的問題。 美國基因組學先驅克萊格.凡特(Craig Venter)宣布,在他位於馬里蘭州和加州的實驗室,科研人員在其為期15年的研究項目中,已成功製造出全球首個“合成細胞”,一種稱為絲狀支原體的細菌。

    新的生命由此誕生,這種新生的微生物能夠生長、繁殖,並產生一代又一代的人造生命。植入的DNA片段包含約850個基因,而人類的DNA圖譜上共有約20000個基因。 這個人造生命被戲稱為「人造兒」(synthia),它是人類科學史上一個革命性的成果,為今後人造微生物的應用研究鋪平了道路。

    身為人類而創造生命,實在令不少人側目,尤其是宗教界人士。加拿大的國際科技監察機構ETC批評科學妄圖扮演上帝,並警告說,合成細胞科技不足以解決我們的一切社會問題,反而會帶來令人更頭痛的新問題。http://www.takungpao.com/news/10/05/22/images_0702-1261367.htm

    Scientists Create Synthetic Organism

    The WallStreet Journal May 21, 2010

    Heralding a potential new era in biology, scientists for the first time have created a synthetic cell, completely controlled by man-made genetic instructions, researchers at the private J. Craig Venter Institute announced Thursday. Created at a cost of $40 million, this experimental one-cell organism, which can reproduce, opens the way to the manipulation of life on a previously unattainable scale, several researchers and ethics experts said. Scientists have been altering DNA piecemeal for a generation, producing a menagerie of genetically engineered plants and animals. But the ability to craft an entire organism offers a new power over life, they said. For the first time, someone has generated an entire artificial cell with predetermined properties.Several companies are already seeking to take advantage of the new field, called synthetic biology, which combines chemistry, computer science, molecular biology, genetics and cell biology to breed industrial life forms that can secrete fuels, vaccines or other commercial products.

    Scientists create synthetic cell

    Cnet News May 20, 2010

    The team of 25 researchers took Mycoplasma capricolum bacteria and completely rewrote its genetic code of more than 1 million base pairs of DNA. The data was sequenced as chemical DNA fragments and sewn together using yeast and E. coli bacteria.

    The synthetic genome was transplanted into empty Mycoplasma mycoides bacteria, which were transformed into a new species. The creature's software-like name, JCVI-syn1.0, reflects its status as the first of its kind. 

    Although the cell is primitive and lacks its own membrane, the techniques developed to create it promise groundbreaking advances in gene engineering and the rise of designer genomes. The achievement also raises ethical questions, not only about the creation of artificial life but the legitimacy of patenting it.

    Researchers Say They Created a ‘Synthetic Cell’

    The New York Times, May 20, 2010

    Synthetic Genomics has a contract from Exxon to generate biofuels from algae. Exxon is prepared to spend up to $600 million if all its milestones are met. Dr. Venter said he would try to build “an entire algae genome so we can vary the 50 to 60 different parameters for algae growth to make superproductive organisms.”

    On his yacht trips round the world, Dr. Venter has analyzed the DNA of the many microbes in seawater and now has a library of about 40 million genes, mostly from algae. These genes will be a resource to make captive algae produce useful chemicals, he said.

  • 終於信了主! 成為基督徒了.

    原著 祈禱真奇妙嗎? (原作者默子)
    http://hk.myblog.yahoo.com/lck-mokche/article?mid=10112

    信德的奧蹟, 奇妙恩典

    默子有個基督徒朋友,大概是耶毒入了腦果隻。

    日前,她好像幹了甚麼偉大事業似的,

    滿懷欣喜地對默子說: 〔我的媽媽一向崇拜佛敎偶像, 十分抗拒我講天主/耶穌的道理。 她近年患病,我每次探她都為佢祈禱,教佢祈禱, 又同佢講聖經故事...... 真係感謝主!祈禱真的十分奇妙!

    佢最近竟然很開心,不再恐懼死亡/病痛。

    佢聽我講聖經故事之時好投入; 我為佢祈禱後,她竟說:耶穌真好!....〕

    她說到幾乎掉出淚水,

    我輕聲問她:伯母患甚麼病呢?

    她好〔神氣〕的說:佢患的是老人痴呆症!

    很多科學家在死前"被"受洗。 死後, 教會就會作宣傳.

    愛因斯坦則被直接宣傳為基督徒已很多年,
    近兩年才被平反為無神論者. 愛因斯坦終於含冤得雪!
