A cockrocher(cockroach) community recently has(had) its collective mind changed by a group of tiny robots. Certain animals engage in what’s known as self-organization. (Picture) a school of fish or a flock of birds. Scientists has been researching autonomous robot system based on this concept --- what about mixed groups of, say, bots and bugs? A paper detailing this new animal-robot cooperation was published in November 16th issue of Science. First, cockrochers were left alone in an area with two choices of shelter. After scurring(scurrying) around, the group chose the darker shelter; then came the robots, they looked(look) nothing like cockrochers. In fact, they more closely resemble tiny trucks. But apparently they smelled enough like the rochers to trick the insects. The robot rochers were trained to prefer the lighter shelter. They behaved like cockrochers and eventually convinced the group to choose the lighter shelter in more than half of the trials. But the robots were sometimes convinced by the rochers too. In 40 percent of the trials, they joined the real live rochers and the group chose the darker shelter. The work signals a new approach for future research in animal-machine collaboration

生词
scurry ---- to move about or proceed hurriedly （才想起来，红宝书里面原来有这个单词，唉，怎么背的单词？）

In September 2005 I attended the beginningof the now famous  Dover PennsylvaniaEvolution versus Intelligent Design trial. I waspresent for opening arguments by both sdies, and I was also in the court room forthe testimony of expert witness Cane Miller, a well-known evolutionarybiologist and author from Brown University.Throw out your TV-drama-influenced notions of the assured lawyer with nervouswitness into reaction（interaction）. Miller easily parryed every attack by the lawer for the intelligent design side. On November 13ththe PBS TV program Nover debuted two-hour episode devoted to the Dover trial. It included re-enactments of some of the most compellingsections of the actual courtroom testimony, including some of Cane Miller’s.And the segmony（segment） which witnesses clearly show theevolution of the intelligence design textbook from its creation storygence(creationist origins) isironically delecious （delicious） The nover(NOVA) show is repeated numerous time this week, and it’salso available in its entirety at PBS.org/nova/id startingNovember 16th.

背景信息
IntelligentDesign, a young movement of scientists who want toquestion Darwinism and prove, if they can, that the universe shows evidence ofcreation by some transcendent mind.

11.20 COMPUTER DOESN'T KNOW WHAT IT LIKES BUT KNOWS ART

If you’ve spent any time in an art museum, you’ll probably learn to appreciate the styles of different artists. You can walk into a room and say,” Oh, that’s Matisse!” You may recognize the colors, the brush strokes, the subject choice, even if the artist incorporated other styles into the painting. Researchers at the University of H, Israel, wanted to teach a computer to do the same thing. The scientist developed a system by which the computer breaks down the image and analyzes as there are aspects of it. People, flowers and other elements get represented with complex mathematics. After repeatedly analyzing the brush strokes and content of say Salvador Dalí painting, the computer learned his particular style well enough to look at the new image and determine whether Dalí himself painted it. This worked even when the art contained a variety of influences. The programs more replace professional expert judgement any time soon. The researchers say it’s another step towards teaching computer how to see the world around them.

把今天的补了;) 听说有官方文稿了 可是不知道怎么下。、

Those clever little monkeys are on strike again. And I don’t mean the Writers Guild. No, I’m talking about the tufted capuchin monkeys at Yerkes Primate Research Center. Those headstrong primates have put down their feet—all four of ‘em—and refused to work for unfair wages. Their grievances are presented in the current online edition of the Proceedings of the National Academy of Sciences.

To examine capuchins’ sense of fairness, Frans de Waal and his colleagues at Emory University designed a bartering task in which monkeys are given tokens they can then exchange for food. Some monkeys get a plain old cucumber slice, others get a coveted grape. What the researchers discovered is that when monkeys who get salad fixins see their friends get fruit, they basically refuse to play anymore.

But were the monkeys really reacting to inequity, thinking, “That’s not fair: She got a grape and I didn’t”? Or were they just being greedy? “I see grapes. I want one.” Or maybe they’re frustrated. “Last time I got a grape—now this?”  The current study suggests that the grapeless monkeys indeed consider themselves shortchanged. Tests to see what they might type given an infinite amount of time are on hold until both labor disputes are settled.

Last year scientists witnessed the dazzling death of a most unusually star. The resulting supernover was about a hundred times brighter than a typical supernova. Standwoosely(Stan Wooseley), a professor of astronomy and astrol physics(astrophysics) at the University of California, at Sant Cruise(Santa Cruz) had an idea about what might have caused the dramcatially demise. He and his collegues published the results in the November 15th issue of Journal Nature. First, you need a star that is at least 19 times than(多了) mass of our sun. As the star nears death, the core gets super hot. Gama ray(Gammy-ray) radiation transforms into pairs of electrons and their antimatter counterparts --- pozertrons(positrons).The core beomes so unstable that pressure drops and the star contracts. It callapses and then quickly expands, then explodes. But the star is so big, the explosion does not destroy the entire star. The process happens again, and the second explosion collides with the remains of the first. This produces an increasingly radiant fireworks display. The possing(pulsing) can theoretically continue up to six times. Who said you only live or die once?

Vocabulary & useful expressions

astrophysics
19 times sth.(weight, mass, ...) of sth.
positron 正电子
pulsing

We all have to make choices, like whether to get the cheese-cake or the apple-pie? Well agonize no longer because a study published online in the journal Nature Neural Science suggested that it doesn't matter which you choose. That just being able to make a choice is rewarded(reward) itself. Researchers of the University of Marilyn's（Maryland） school of medicine were studying how neurons in the pleasure center of rats' brains respond to different rewards. In their test, rats could belly up to one of two bars to recieve a tasty sip of sugar water. At one of the truft（troughs）, the drinker was bigger and waiting time less. But here is the catch, at the start of each trial, the rat will receive a signal telling him which one he could have. One said "You've won the big prize", a second said "You get the consollation（consolation） prize", and the third said "Pick whichever you want". Well as you might expect, when the rat knew it'll （had hit）hit the jack-part（jackpot）, neurons in its pleasure center jumped for joy. But these happy cells reacted the exact same way in rats who were allowed to choose, without knowing the animals were known（whether or not the animals went on） to claim the better prize. So cheese-cake, apple-pie, whichever, just relax and save the deliberation.

11-21 ICU paradox: Death gets better grades.

Having a lot in the hospital, especially the intensive care unit or ICU, can be a heroin experience. And it’s even traumatic for the families of those passed away, or so you think. But accordingly to a studying published in the November issue of the journal Chest, families whose loved ones die in the ICU tend to be more satisfied with the care received than those whose loved ones survived. Although the result seems paradoxical, when you look more closely how people define quality of care, they do make sense. All patients went into? the ICU, whether or not they walk out, receive the similar standard care from the ? medical of you. But doctors, nurses and other hospital staff may devote extra time of tension to the needs of family whose loved ones are near the end. That compassion is what families who lose loved one are responding to when they report more satisfactory ICU experience. Just having some one who explain what’s going on, answer the questions and offer emotional support makes all the difference. An observation that in the end maybe not so surprising.


BTW， 想问下怎么上传mp3？

Having a loved one in the hospital, especially the intensive care you need(unit) --- or ICU --- can be a harrowing experience. And it's even more tromatic(traumatic) for the families of those who pass away. Or so you(you'd) think. But according to a study pulished in the November issue of the journal Chest, families whose loved ones die in the ICU tend to be more satisfied with the care they received than those whose loved ones survive. Althoutgh the result's (results seem) parodoxical, when you look more closely at how people define the quality of care, they do make sense. All patients who wind up the ICU, whether or not they walk out, recieve a similar standard of care from a strictly medical point of view. But doctors, nurses and other hospital staff may devote extra (tie) many （time and）attention to the needs of families whose loved one is near the end. That compassion is what families who lose a loved one are responding to when they report a more satifactory ICU experience. Just having someone who'll explaining what's going on, answer the questions, and offer an emotional support makes all the difference. And(An) observation that in the end, this(is) maybe not so surprising.

Vocabulary
traumatic ---- psychologically painful;
wind up ---  to come to an end （在这里可能是 “死翘翘” 的意思吧）
但是这句话是什么意思呢？
All patients who wind up the ICU, whether or not they walk out
那些在医院里面死翘翘的病人，无论他们有没有走出去（走出哪里？？） 我愿意为是不管那些病人有没有活着走出医院，都接受同样的治疗
