美國‧傳宗接代無需性伴侶‧人工精卵5年成真

(美國‧華盛頓)人類生育醫學取得驚人突破,以後男女女,生兒育女,只需靠自己!

美國科學家已成功培育出人工精子和卵子的雛形,意味著男人女人傳宗接代的天職,可由實驗室代替!

美國史丹福大學科學家佩拉領導的研究小組,在新一期《自然》科學雜誌,發表了這項足以改變生命之源的研究成果。

科學家利形成只有數天的早期胚胎進行實驗,抽取出幹細胞,混合不同的化學物質和維他命,成功誘使一些細胞發展成為配子細胞,即類似精子或卵子等成熟的生殖細胞。

利用這種方式製造出來的精子,有頭部和短短的尾巴,相信有能力令卵子成孕;至於利用這種方法製造出來的卵子,則仍然處於極早期階段,但比其他同類研究,向前邁進了一大步。

佩拉預計,人工精子和卵子技術5年後便夠成熟,可正式投入應用。

儘管新技術可幫助不育夫婦及同性戀者透過人工精卵生育下一代,但也引起道德爭議,或會破壞家庭倫理,因為人類將來可以透過人工方式培育“人工寶寶”,即使沒有性伴侶,也可以有下一代,婚姻和父母的角色將會變得可有可無。

皮膚細胞培育精子卵子

科學家下一步是希望用成人的皮膚細胞,“倒撥”其生理時鐘,將之“還原”為胚胎幹細胞,再培育成精子和卵子。

在新技術下,理論上經由皮膚細胞便可孕育出精子和卵子,即男性用皮膚細胞就可造出卵子,女性則可造出精子,男人或女人都可單性繁殖下一代,但男性仍要靠代母懷胎。

不過,由於女性細胞沒有男性的Y染色體,科學家對是否能用來製造“女性精子”存疑。

女性染色體是XX,男性是XY。由於男性有X染色體,用男性幹細胞製造卵子不難;但女性染色體只有X沒有Y,所以用女性皮膚製造精子,複雜困難得多。

加拿大‧詐騙曼谷銀行3億‧流亡金融家被引渡回泰

(加拿大‧溫哥華)詐騙泰國曼谷商業銀行巨額款項的印度裔金融家拉克什,在加拿大流亡多年後,於週四(10月29日)被遣送到泰國。

泰國官員指有關詐騙案是導致1990年代亞洲金融危機的因素之一。

拉克什被控挪曼谷商業銀行8800萬美元(約馬幣3億令吉)鉅款,為避免被引渡,他與加拿大移民部打了13年的官司。而曼谷商業銀行已於1995年倒閉。

加拿大司法部女發言人肯汀指出,他們已把拉克什移交給泰國當局,目前他正被押送到泰國。據律師指出,拉克什將從溫哥華先抵達北京,再轉機到曼谷,預料他將在今日(週五,10月30日)晚抵達。

加拿大最高法院週四駁回審理拉克什案件的要求,啟動了遣送拉克什的程序。

3月時中風須坐輪椅

拉克什在今年3月中風後不良於行,必須依靠輪椅移動。在打官員期間的軟禁期,他大多數時間是在位於溫哥華的豪宅中渡過。

泰國檢察長辦公室一名發言人表示,拉克什面對20項控狀。

拉克什曾在曼谷商業銀行擔任顧問,他在1996年被控侵吞這間銀行公款,而遭泰國警方發出逮捕令。拉克什隨後逃離到加拿大,但當年稍後被逮捕。

荷蘭‧患怪病後獨沽一味‧婦女吃下78隻匙叉

(荷蘭‧鹿特丹)日本卡通片《IQ博士》裡的小吉吃螺絲,但強中自有強中手,荷蘭一名婦女不吃螺絲,獨沽一味吃餐具,直到胃痛求醫,醫生一看X光片嚇傻了眼,因為因為她肚里有78隻匙叉!

荷蘭醫學雜誌《精神病在線雜誌》近日呼吁讀者提供怪病紀錄,首次公開這宗30年前發生的個案。


這張X光照是在30年前拍下的,但依然震撼醫學界。醫生在達爾曼胃中發現一大團白影,起初以為是一條大墨魚,觸鬚特別多,但仔細檢查下,赫然發現是一大堆餐具,那些“觸鬚”其實是糾纏在一起的叉叉匙匙,足足有78隻之多。(圖:互聯網)

患者是52歲秘書達爾曼,30年前,年僅22歲的她某天因胃痛難忍,到鹿特丹一家醫院檢查,

診斷結果令人瞠目結舌:她的胃裡竟然有78隻銀製匙子和叉子。

醫生立即為她實施了手術,將胃中的匙叉一隻接一隻取出來。在場的醫生和護士十分不解,她為甚麼會吞餐具。

從不吃刀

原來,達爾曼患上奇怪的“邊緣型人格失調症”,每次坐到餐桌前,看見滿桌美味食物,她會口水直流,但她覺得美味的不是食物,而是擺在兩旁的叉和匙。開餐了,她就會情不自禁地拿起叉和匙一個勁兒地往嘴裡塞,“骨碌”一聲吞下。

奇怪的是,達爾曼從不吃刀,連自己也無法解釋。

手術後,達爾曼接受了針對邊緣性人格障礙的治療,現已完全康復,並恢復了正常人的飲食習慣。

新加坡‧每小時500顆‧11月18有流星雨

(新加坡)今年11月18日清晨5時,數以萬計的獅子座流星雨將劃過新加坡天空。

新加坡天文學會會長林志雲受訪時說,這次的獅子座流星雨估計可達每小時500顆,算是“半個暴風雨”。一般來說,每小時可見1000顆流星時,稱為“暴風雨”。

“這次獅子座流星雨出現的時候,正逢沒有月光,因此公眾能看到不受月光影響的流星雨。”

他表示,曾於2001年在泰國與其他20名天文學會成員,見證過獅子座流星暴風雨。

“那是所見過最壯觀的天文景觀之一。”

針對11月18日的流星雨,他說,雖然清晨5時是被認為是最適合看流星雨的時間,但由於是預測的時間,因此流星雨很可能從11月17日午夜就開始,並隨著破曉而加劇。

如果公眾想見證這美麗的一刻,林志雲建議在一個黑暗,並能不受阻擋地看到東方的地方觀看。

中國‧半空起火逾百乘客驚魂‧貴州客機驚險降落

(中國‧貴州)中國一架載有逾百乘客的客機,從江西南昌飛往貴州貴陽途中機頭突然起火,冒煙驚險飛行個多小時後平安降落。

據《貴陽晚報》報導,由於起火位置於機頭,機上的逾百乘客,於事發時毫不知情。

上演九霄驚魂的客機是於週三(10月28日)上午9時40分於南昌起飛,飛至湖南長沙上空時,機師驚見擋風玻璃前有煙霧飄過,機組人員檢查後發現,機頭左邊著火冒煙,即動滅火器救火。

機師向貴州民航局求救,在民航局專家指導下展開搶救工作。

報導指,雖然其後飛機火勢已受控制,但仍然冒煙,隨時有墜機可能,情勢危急。機組人員為免造成恐慌,並未向乘客通報。

客機在飛行近1小時後,進入貴州上空,為控制火勢,機師降低飛行高度,由9300公尺降至3600公尺,一度準備逼降就近的銅仁機場。

但民航局地面控制中心無法正常指揮客機,為安全起見,客機唯有放棄臨時降落銅仁,直飛貴陽。

冒煙客機在飛行半小時後進入貴陽,至11時06分,拖著一道黑煙的客機,終於安全降落貴陽機場,機上所有乘客無恙。

經當局初步調查,飛機起火是由於機內風擋設備電線短路引致,但確實原因仍有待進一步調查。

Cluster Bomb Trade Funded by World's Biggest Banks

HSBC earned more than £650m in fees from work for Textron, US manufacturer of cluster weapons


The deadly trade in cluster bombs is funded by the world's biggest banks who have loaned or arranged finance worth $20bn (£12.5bn) to firms producing the controversial weapons, despite growing international efforts to ban them.

[]
HSBC, led by ordained Anglican priest Stephen Green, has profited more than any other institution from companies that manufacture cluster bombs. The British bank, based at Canary Wharf, has earned a total of £657.3m in fees arranging bonds and share offerings for Textron, which makes cluster munitions described by the US company as "leaving a clean battlefield".

Campaigners maintain the deadly weapons can explode years after combat, killing or maiming innocent people.

HSBC will face protests outside its London headquarters today. Goldman Sachs, Bank of America, JP Morgan and UK-based Barclays Bank are also named among the worst banks in a detailed 126-page report by Dutch and Belgian campaign groups IKV Pax Christi and Netwerk Vlaanderen.

Goldman Sachs, the US bank which made £3.19bn proft in just three months, earned $588.82m for bank services and lent $250m to Alliant Techsystems and Textron.

Of the banks named, only Barclays was prepared to comment. It said: "Barclays group provides financial services to the defence sector within a specific policy framework. It is our policy not to finance trade in nuclear, chemical, biological or other weapons of mass destruction.

"Our policy also explicitly prohibits financing trade in landmines, cluster bombs or any equipment designed to be used as an instrument of torture." A spokeswoman added that Barclays had supplied money to Textron, which makes cluster bombs, but that the US firm was a broad-based weapons manufacturer.

Last December 90 countries, including the UK, committed themselves to banning cluster bombs by next year. But the US was not one of them. So far 23 countries have ratified the convention. The UK has yet to do so, but the Foreign Office confirmed that it would form part of the government's legislative programme before the next election.

A Foreign Office spokesman said the tightest export control order had been placed on cluster bombs, which extended to banks supplying money to manufacturers. The government was aware the control order was not working and "is working on it".

Esther Vandenbroucke, of Netwerk Vlaanderen and one of the report's authors, said: "The responsibility to ban cluster munitions is a shared responsibility. It requires courage, and it requires an effort. We are just months away from an international treaty entering into force and it is time for signatory states to the Convention on Cluster Munitions for non-signatory states and for financial institutions to act now."

Last December, the New Zealand government's pension fund sold shares in Lockheed Martin because of its link to the manufacture of cluster bombs. Similar actions have been taken by the Irish and Dutch governments.

Millions of people will be endangered by up to tens of millions of cluster bomblets that have not yet exploded, causing lasting economic and social harm to communities in more than 20 countries for decades to come, campaigners have warned. The vast majority of cluster bomb casualties occur while victims are carrying on their daily lives.

On Monday, a Lebanese 20-year-old man had his leg amputated after a cluster bomb exploded in southern Lebanon Houla village. A security source said he was collecting wood in his border village when the explosion occurred.

The Israeli army made extensisve use of cluster bombs during the war in south Lebanon three years ago. Cluster bombs were most recently used by both the Georgians and the Russians in the dispute over South Ossetia. They were also used in the Iraq and Afghanistan invasions.
