Astudy of billions of instant messages has validated the idea that there are about six degrees of separation between any two people on the planet.
A team at Microsoft studied 30 billion instant messages sent by 240 million people in June 2006 and found that, on average, any two could be linked in 6.6 steps.

“We’ve confirmed that it is indeed a small world,” said Microsoft researcher Eric Horvitz.
“Over the next few decades, new kinds of computing programs will help make the world even smaller, with closer social connections and deeper understanding among people.”
“To our knowledge, this is the first time such a large social network has been available to validate the well-known six degrees of separation finding.”
The researchers say that they couldn’t read the contents of messages and that information about people’s identities was removed.
The six degrees of separation idea comes from a 1969 study by Stanley Milgram and Jeffrey Travers. They asked nearly 300 people in the US state of Nebraska to send a letter to someone in Boston through acquaintances.
People were considered one degree apart from a friend, two degrees away from a friend’s friend and so on.
While most of the letters didn’t make it to the person in Boston, those that did arrived with an average of 6.2 degrees of separation from senders.
The results have inspired a play, a film, a game, and a Web site launched by actor Kevin Bacon. (AFP)
一項針對數百億通即時訊息進行的研究結果證實,六度分隔理論的概念確實存在於全世界任兩人之間。
微軟公司一組研究團隊針對二OO六年六月間,兩億四千萬人傳送出的三百億通即時訊息進行研究,結果發現任兩人之間,平均透過六點六個人就可以建立起關聯。
微軟研究員艾瑞克.賀維茲說:「我們證實了這個世界真小。」
「未來數十年,新的電腦程式將更縮短地球村的距離,讓社交關係變得更密切,人與人之間也能更深入了解。」
「據我們所知,這是首度有人利用這麼大範圍的社交網絡,來證實知名的六度分隔理論。」
研究人員表示,他們看不到訊息的內容,而且民眾的個人資料也都被刪除。
六度分隔的概念是史丹利.米爾葛倫和傑弗瑞.崔佛斯在一九六九年所提出。他們請美國內布拉斯加州的近三百名居民,透過認識的人將一封信轉寄給在波士頓的某人。
和朋友間的關係是一度分隔,和朋友的朋友間的關係則是兩度分隔,依此類推。
然而大部分的信並沒有被轉寄到波士頓那名人士手中,至於寄達的那些信,則平均透過六點二個寄信者中介。
這些結果也成為戲劇、電影、遊戲及一個由影星凱文.貝肯所架設的網站的靈感來源。

An automated human washing machine was one of the highlights at the Osaka Kansai Expo, giving visitors a glimpse into the future of personal hygiene technology. As part of the event, 1,000 randomly selected visitors were given the chance to try out this cleansing system. The machine operates as a capsule-like chamber where warm water filled with microscopic bubbles gently washes away dirt. The 15-minute process also includes a drying phase, removing the need for users to dry themselves manually. Equipped with advanced sensors, the device monitors the user’s biological data, such as their pulse, to adjust water temperature and other settings
Britain’s National Gallery announced on Sept. 9 that it will use a whopping £375m (US$510m) in donations to open a new wing that, for the first time, will include modern art. Founded in 1824, the gallery has amassed a centuries-spanning collection of Western paintings by artists from Leonardo da Vinci to J.M.W Turner and Vincent van Gogh — but almost nothing created after the year 1900. The modern era has been left to other galleries, including London’s Tate Modern. That will change when the gallery opens a new wing to be constructed on land beside its Trafalgar Square site that is currently
It is a universally acknowledged truth that Jane Austen, born in 1775, is one of the most beloved English novelists, and that her works still inspire readers today. She is renowned for her novels Pride and Prejudice, Emma, and Sense and Sensibility. Her stories often explore themes of love, marriage, and social status in late 18th-century British society and are written with wit and insight. To honor her legacy, the Jane Austen Festival is held every September in Bath, England. She lived there for several years, and the city is depicted in two of her novels. The festival began in 2001
Firefighters might face an increased risk of developing “glioma,” a type of brain cancer, due to certain chemicals encountered on the job. A recent study analyzed glioma cases and found clear connections between the genetic patterns of affected firefighters and their exposure to these harmful substances. The study found that firefighters exhibited significantly higher levels of specific mutational signatures in their glioma cells compared to individuals in other occupations. These signatures — unique patterns of genetic changes in DNA — help scientists trace the source of mutations. Earlier research has associated these mutations with certain chemicals found in fire
