Police forces should issue funny caricatures of the criminals they are hunting, a team of scientists in England said. The scientists said that cartoon-like faces are better than normal photos at jolting people's memories.
The study found that exaggerating features on people's faces made them twice as easy to identify as before.
The scientists turned the faces of 18 celebrities into caricatures by exaggerating some features. For example, they made people's ears, foreheads or noses bigger.

The scientists then used the caricatures in tests. Volunteers were asked to identify people from normal photos and from the caricatures.
On average, a normal photo face was correctly identified 20% of the time. Caricature faces were correctly identified 40% of the time.
The scientists are talking with police about maybe using caricatures to help catch criminals.

英國某科學團隊指出，警方應發布通緝中罪犯的Q版畫像。科學家認為，卡通人像比一般照片更能激起民眾的記憶。
這項研究發現，和傳統相片比較起來，誇張的臉部特徵能讓指認工作事半功倍。
科學家以誇大部份特徵的手法為十八位名人製作Q版畫像，例如把他們的耳朵、額頭或鼻子畫大。
然後他們將這些Q版畫像用在測驗中，要求自願受試者從普通相片和漫畫肖像中辨識人物。
平均來說，該實驗正常相片的正確辨認率僅有兩成，而Q版畫像則有四成。
科學家建議警方，也許可以利用Q版畫像來協助緝捕罪犯。（衛報�翻譯：袁星塵）
Photographer Franziska Stuenkel likes to take spontaneous urban shots, so she needs a nimble camera that is ready to go when inspiration strikes: her German-made Leica M11. “I have to be very quick and discreet,” said the Berlin-based artist who captures reflections of people walking past windows, their contours merging with the shapes behind the glass. Stuenkel’s compact Leica is the perfect camera for the job, the 51-year-old told AFP. Famous for its pocket-sized and retro-style devices, the Leica brand is celebrating a milestone as it marks 100 years since its first commercial camera was presented to the public. The
Picture a 45-foot-long animal with a 5-foot-long skull and 3-foot-long arms. It may not seem strange until you realize that a human with those proportions would be 6 feet tall with 5-inch arms. Although the Tyrannosaurus rex went extinct 65 million years ago, the mystery of its unusual body __1__ has fascinated scientists for over a century. Barnum Brown, the paleontologist who first discovered T. rex fossils, initially found it hard to believe that the tiny arms belonged to such a __2__ creature. One of his colleagues speculated that the short forelimbs might have been used to hold the
A: Actually, Brazilian jiu-jitsu is particularly good for small people like you. B: Really? How so? A: According to Diana Wang, a US doctor of physical therapy, the BJJ’s purpose is to help smaller, weaker people defend themselves by using various techniques, such as leverage. B: That sounds interesting. What time does Dr Wang’s BJJ seminar begin tonight? A: The event is scheduled for 7:30pm at PMA Brazilian Jiu-jitsu in Taipei. Admission is free, but donations are welcome. A: 其實你的個子比較小，很適合練巴西柔術呢。 B: 真的嗎？為什麼？ A: 據美國理療醫師王幼瑞博士說，巴西柔術的概念是讓弱小的人，也能利用槓桿作用等技巧防身。 B: 真有趣，王醫師的巴柔研討會幾點開始？ A: 今晚7點半在「台北巴柔運動館」，免費入場自由樂捐唷！ （By Eddy Chang, Taipei Times／台北時報張迪）
Dogs’ noses are incredibly keen. They can even detect changes in cortisol levels in human sweat and breath. Known as the “stress hormone,” cortisol increases when humans are under pressure. Recent research indicates that the smell of human stress can influence a dog’s behavior and emotions. In the study, human volunteers were exposed to the stressful tasks of preparing and delivering a speech on the spot and then solving math problems. __1__ Researchers collected sweat and breath samples from the volunteers on pieces of cloth during both their stressful and restful states. Meanwhile, other researchers worked with 18
