Dr. Stanley Hazen of the Cleveland Clinic, who led the study, and his colleagues had accumulated evidence for a surprising new explanation of why red meat may contribute to heart disease. And they were testing it with this early morning experiment.
The researchers had come to believe that what damaged hearts was not just the thick edge of fat on steaks, or the delectable marbling of their tender interiors. In fact, these scientists suspected that saturated fat and cholesterol made only a minor contribution to the increased amount of heart disease seen in red-meat eaters. The real culprit, they proposed, was a little-studied chemical that is burped out by bacteria in the intestines after people eat red meat. It is quickly converted by the liver into yet another little-studied chemical called TMAO that gets into the blood and increases the risk of heart disease.
研究人員逐漸認識到，對心臟有害的不僅是牛排邊角上厚厚的肥肉，或中間幼嫩美味的大理石狀肉。事實上，這些科學家懷疑，飽和脂肪和膽固醇只是喜食紅 肉者心臟疾病多發的一小部分誘因。他們提出，真正的罪魁禍首卻是一種在人們吃了紅肉以後由腸道內細菌釋放出來的化學物質，此前甚少有人研究。這種物質會很 快被肝臟轉化成另一種少有研究的化學物質，稱為氧化三甲胺(TMAO)，進入血液後增加心臟病的風險。

Coffee aficionados have been asking the question: Is Portland's Stumptown Coffee Roasters the new Starbucks?
A great deal of Mr. Hemingway's work showed a preoccupation--frequently called obsession--with violence and death. He loved guns; he was one of the great aficionados of the deadly bullfight. He identified with the adventures of partisan warfare; he swung a burp-gun in guerrilla fighting.
With tea's popularity it was the most likely choice as the beverage for this new meal, but given that Anna's brother Viscount Petersham was a great tea aficionado whose sitting room contained canisters of tea in great variety coffee and chocolate didn't have a chance.
IN THE NEWS / User-friendly kanji漢字 dictionary popular
Katsumi Kokoma had always been dissatisfied with conventional kanji dictionaries. The reference works, he said, generally exclude some characters, such as nabe-bugyo--describing a person who is bossy about how to eat a nabe stew--despite their frequent use in Japanese novels.
Kokoma, who works in the proofreading section of Shinchosha Publishing Co., came up with the idea of publishing a user-friendly kanji dictionary for Japanese people. Completing the tome took more than 10 years, with all the work done without help from scholars.
Titled Shincho Nihongo Kanji Jiten, the dictionary was published at the end of September with an initial print run of 10,000 copies. But it turned out to be so popular that the publisher ordered a second printing--unusually soon for such a work.
Kokoma, 53, has been a kanji aficionado for as long as he can remember. Even before entering primary school, he asked his parents to buy books written with kanji. When he entered the school, he was given a kanji dictionary. He perused the dictionary so much that it soon became worn out.
As a college student, he began taking part in kanji reading and writing competitions, on one occasion winning a national championship.
"I never get bored of the way kanji organically combine meaning and form," Kokoma said.
He joined Shinchosha in 1989, after working at several other publishers. In 1996, he submitted a proposal for a kanji dictionary and got approval from the publisher.
He began compiling it in 1998 in a two-story wooden building behind the company's main building.
Many people were puzzled about what he was doing there.
"Now that I've completed my work, I feel that I can die happy," he said emotionally, cradling a copy of the dictionary.
Last month, Kokoma took a long vacation to visit China for the first time. He was excited about viewing the Stele Forest in Xian, Shaanxi Province, which features thousands of stone stelae carved with Chinese characters. 碑林
