The immune system is equal in complexity to the combined intricacies of the brain and nervous system. The success of the immune system in defending the body relies on a dynamic regulatory communications network consisting of millions and millions of cells. Organized into sets and subsets, these cells pass information back and forth like clouds of bees swarming around a hive. The result is a sensitive system of checks and balances that produces an immune response that is prompt, appropriate, effective and self-limiting. At the heart of the immune system is the ability to distinguish between self and non-self. When immune defenders encounter cells or organisms carrying foreign or non-self molecules, the immune troops move quickly to eliminate the invaders. Virtually every body cell carries distinctive molecules that identify it as self. The body's immune defenses do not normally attack tissues that carry a self marker. Rather, immune cells and other body cells coexist peaceably in a state known as self-tolerance. When a normally functioning immune system attacks a non-self molecule, the system has the ability to remember the specifics of the foreign body. Upon subsequent encounters with the same species of molecules, the immune system reacts accordingly. With the possible exception of antibodies passed during lactation, this so-called immune system memory is not inherited. Despite the occurrence of a virus in your family, your immune system must learn from experience with the many millions of distinctive non-self molecules in the sea of microbes in which we live. Learning necessitates producing the appropriate molecules and cells to match up with and counteract each non-self invader. Any substance capable of stimulating an immune response is called an antigen. Tissues or cells from another individual (except an identical twin, whose cells carry identical self-markers) act as antigens; because the immune system recognizes transplanted tissues as foreign, it rejects them. The body will even reject nourishing proteins unless they are first broken down by the digestive system into their primary, non-antigenic building blocks. An antigen announces its foreignness by means of intricate and characteristic shapes called epitopes, which stick out from its surface. Most antigens, even the simplest microbes, carry several different kinds of epitopes on their surface, some may even carry several hundred. Some epitopes will be more effective than others at stimulating an immune response. Only in abnormal situations does the immune system wrongly identify self as non-self and execute a misdirected immune attack. The result can be so-called autoimmune disease. The painful side effects of these diseases are caused by a person's immune system actually attacking itself.

The Bush administration is going to propose far-reaching new rules which would give people with disabilities greater access to tens of thousands of courtrooms, swimming pools, golf courses, stadiums, theaters, hotels and retail stores. The proposal would substantially update and rewrite federal standards for enforcement of the Americans With Disabilities Act, which is a landmark civil rights law passed with strong bipartisan support in 19 90. The new rules would set more stringent requirements in a lot of areas and address some issues for the first time, in an effort to meet the needs of an aging population and increasing numbers of disabled war veterans. More than seven million businesses and all state and local government agencies would be influenced. The proposal includes some exemptions for parts of existing buildings, but any new construction or renovations would have to comply. The new standards would affect everything from the location of light switches to the height of retail service counters, to the use of monkeys as "service animals" for people with disabilities, which would be forbidden. The White House approved the proposal in May after a five-month review. It will be published in the Federal Register on Tuesday, with 6 0 days for public comment. After considering those comments, the government would issue final rules with the force of law. Already, the proposal is stirring concern. The United States Chamber of Commerce says it would be onerous and costly, while advocates for disabled Americans say it does not go far enough. Since the disability law was signed by the first President Bush, advances in technology have made services more available to people with disabilities. But Justice Department officials said they were still receiving large numbers of complaints. In recent months, the federal government has settled lawsuits securing more seats for disabled fans at Madison Square Garden in New York and at the nation's largest college football stadium, at the University of Michigan. The Justice Department acknowledged that some of the changes would have significant costs. But over all, it said, the value of the public benefits, estimated at ￥54 billion, exceeds the expected costs of ￥23 billion. In an economic analysis of the proposed rules, the Justice Department said the need for an accessible environment was greater than ever because the Iraq war was "creating a new generation of young men and women with disabilities." John L. Wodatch, chief of the disability rights section of the Justice Department, said: "Disability is inherent in the human condition. The vast majority of individuals who are fortunate enough to reach an advanced age will benefit from the proposed requirements."

Success, it is often said, has many fathers—and one of the many fathers of computing, that most successful of industries, was Charles Babbage, a 19th-century British mathematician. Exasperated by errors in the mathematical tables that were widely used as calculation aids at the time, Babbage dreamed of building a mechanical engine that could produce flawless tables automatically. But his attempts to make such a machine in the 1920s failed, and the significance of his work was only rediscovered this century. Next year, at last, the first set of printed tables should emerge from a calculating "difference engine" built to Babbage"s design. Babbage will have been vindicated. But the realization of his dream will also underscore the extent to which he was a man born ahead of his time. The effort to prove that Babbage"s designs were logically and practically sound began in 1985, when a team of researchers at the Science Museum in London set out to build a difference engine in time for the 200th anniversary of Babbage"s birth in 1992. The team, led by the museum"s curator of computing, Doron Swade, constructed a monstrous device of bronze, iron and steel. It was 11 feet long, seven feet tall, weighed three tons, cost around $500,000 and took a year to piece together. And it worked perfectly, cranking out successive values of seventh-order polynomial equations to 31 significant figures. But it was incomplete. To save money, an entire section of the machine, the printer, was omitted. To Babbage, the printer was a vital part of design. Even if the engine produced the correct answers, there was still the risk that a transcription or typesetting error would result in the finished mathematical tables being inaccurate. The only way to guarantee error-free tables was to automate the printing process as well. So his plans included specifications for a printer almost as complicated as the calculating engine itself, with adjustable margins, two separate fonts, and the ability to print in two, three or four columns. In January, after years of searching for a sponsor for the printer, the Science Museum announced that a backer had been found. Nathan Myhrvold, the chief technology officer at Microsoft, agreed to pay for its construction (which is expected to cost $373,000 with one Proviso: that the Science Museum team would build him an identical calculating engine and printer to decorate his new home on Lake Washington, near Seattle). Construction of the printer will begin—in full view of the public—at the Science Museum later this month. The full machine will be completed next year. It is a nice irony that Babbage"s plans should be realized only thanks to an infusion of cash from a man who got rich in the computer revolution that Babbage helped to foment. More striking still, even using 20th-century manufacturing technology the engine will have cost over $830,000 to build. Allowing for inflation, this is roughly a third of what it might have cost to build in Babbage"s day, in contrast to the cost of electronic-computer technology, which halves in price every 18 months. That suggests that, even had Babbage succeeded, a Victorian computer revolution based on mechanical technology would not necessarily have followed.

【F1】 Japan said Tuesday it had successfully extracted methane hydrate, known as "fire ice", from its seabed, possibly unlocking many years' worth of gas for the resource-starved country. In what they are claiming as a world first, a consortium is drilling for the hydrate, a fossil fuel that looks like ice but consists of very densely-packed methane surrounded by water molecules, one kilometre(3, 300 feet)below sea level.【F2】 The solid white substance burns with a pale flame, leaving nothing but water. One of it is estimated to contain many times the equivalent volume of methane in gas form. The consortium, led by Japan Oil, Gas and Metals National Corporation, began initial work in February last year and on Tuesday started a two-week experimental production, an economy, trade and industry ministry official said. "It is the world's first offshore experiment producing gas from methane hydrate," the official said, adding that the team successfully collected methane gas extracted from the half-frozen substance.【F3】 Under the government-led project, the consortium is to separate methane—the primary component of natural gas—from the solid clathrate compound under the seabed using the high pressures available at depth, officials said. A huge layer of methane hydrate containing 1.1 trillion cubic metres(38.5 trillion cubic feet)in natural gas—equivalent to Japan's consumption of the gas for 11 years—is believed to lie in the ocean floor off the coast of Shikoku island, western Japan, the officials said. 【F4】 "We aim to establish methane hydrate production technologies for practical use by the fiscal 2018 year ending March 2019." a consortium official said. "We want to consolidate technologies for its commercialisation," economy, trade and industry minister Toshimitsu Motegi also told a news conference, according to Jiji Press. "I hope we can make use of resources surrounding our country as soon as possible by clearing hurdles one by one," he added. 【F5】 The move comes as resource-poor Japan has struck out in search of new energy supplies after it shut down its stable of nuclear reactors in the wake of 2011 's tsunami-sparked nuclear crisis.

Like the flu, a person"s emotional state can be contagious. Watch someone cry, and you"ll likely feel sad; think about the elderly, and you"ll tend to walk slower. Now a study suggests that we can also catch someone else"s irrational thought processes. Anyone who"s lost money on a house in need of repair may have suc-cumbed to a classic economic fallacy known as "sunk costs." You make a bad investment in a home that"s never going to sell for more than you put in to it, yet you want to justify your investment by continuing to throw money into renovations. One way to avoid this hole is to get advice from someone who has no self-interest in the project. But is the outsider still somehow susceptible to your mindset? To find out, social psychologist Adam Galinsky of Northwestern University and colleagues asked college students to take over decision-making for a person they had never met—and who they didn"t know was fake. The volunteers were split into two groups: one that felt some connection with the decisionmaker and another that didn"t. In one experiment, the volunteers watched the following scenario play out via text on a computer screen: the fake decision-maker tried to outbid another person for a prize of 356 points, which equaled $4.45 in real money. The decision-maker started out with 360 points, and every time the other bidder raised the stakes by 40 points, the decision-maker followed suit. Volunteers were told that once the decision-maker bid over 356 points, he or she would begin to lose some of the $12 payment for participating in the study. When the decision-maker neared this threshold, the volunteers were asked to take over bidding. Objectively, the volunteers should have realized that—like the person who makes a bad investment in a house—the decision-maker would keep throwing good money after bad. But the volunteers who felt identification with the fake player made almost 60% more bids and were more likely to lose money than those who didn"t feel a connection. Galinsky believes that the results suggest that companies trying to reverse results of bad decisions should find true outsiders. He points to troubled automaker Ford as an example. Instead of hiring from within—as General Motors (GM) recently did—Ford made Alan Mulally from Boeing, an aerospace company, their chief executive officer. Many experts believe that Ford is now recovering quicker than GM. "It"s true that insiders have more knowledge," Galinsky says. "But when you are already down the road of a failed course of action, you really need... a true outsider."

The scientist who wants to predict the way which consumers will spend their money must study consumer behavior. He must 【B1】_______ data both on the resources of consumers and on the motive that 【B2】_______ to encourage or discourage money spending. If an economist were asked which of three groups borrow most—people with rising incomes,【B3】______incomes, or decreasing incomes—he would probably answer, those with 【B4】_______ incomes. 【B5】_______, the answer was: people with rising incomes. People with decreasing incomes were 【B6】_______ and people with stable incomes borrowed least. This shows us that traditional 【B7】_______ about the relation between earning and spending are not always【B8】______. Another traditional assumption is that if people who have money expect prices to go up, they will【B9】______to buy.【B10】______, research surveys have shown that this is not always true. The expectations of price increases may not【B11】______buying. One typical attitude was expressed【B12】______the wife of mechanic in an interview at a time of rising price. "In a few months," she said, "we’ll have【B13】______to spend on other things." Her family had been planning to buy a new car but they postponed this【B14】______. Furthermore, the rise in prices that has already taken place may be disliked and buyer' s【B15】______may be produced. This is shown by the following【B16】______comment: "I just don't pay these prices; they are too high." The investigations mentioned above were【B17】______in America. If prices have been stable and people consider that they are【B18】______, they are likely to buy. Thus, it appears that the common business policy of【B19】______stable prices is based on a correct understanding of consumer【B20】______.

Where is the second centre of Hollywood film making in Europe after London, Paris, or perhaps Berlin? Try Prague. Last year, Hollywood spent over $200m on shooting movies, commercials and pop videos in the Czech capital. This year, all the big studios will be in town. MGM has "Hart"s War" starring Bruce Willis; Disney is shooting "Black Sheep" with Anthony Hopkins; and Fox has just finished filming "From Hell", a Jack the Ripper saga starring Johnny Depp. Praguers take Tinseltown in their stride. Old ladies looked only slightly confused last month when the cobbled streets of Mala Strana, Prague"s old quarter, were cleared of real snow and sprayed with a more cinematically pleasing chemical alternative for Universal"s "Bourne Identity", a $50m thriller starring Matt Damon. The film"s producer, Pat Crowley, reckons a day filming in Prague costs him $100,000, against $250,000 in Paris. Czech crews, he says, are professional, English-speaking and numerous. They are also a bargain—40% cheaper than similar crews in London or Los Angeles, points out Matthew Stillman. the British boss of Stillking, a Prague-based production firm. Mr. Stillman founded Stillking in 1993 after arriving in Prague with $500 and a typewriter. Today, Hollywood producers come to the company for crews, catering, lights and much more. It claims to have about half of the local film-production business and this year hopes for revenues of over $50m. The biggest draw to Prague, however, is Barrandov—one of the largest film studios in Europe, with 11 sound-stages, onsite photo labs and top-notch technicians. It was founded during Czechoslovakia"s pre-war first republic by Milos Havel, an uncle of the present Czech president, Vaclav Havel. The Nazis expanded it as a production centre for propaganda flicks—the sound-stages are courtesy of Joseph Goebbels. Then came the Communists with their own propaganda and, admittedly, a few impressive homegrown directors such as Milos Forman, who began Hollywood"s march to Prague by filming "Amadeus" there. But it is partly thanks to Barrandov that Prague remains some way behind London as a film centre. The studio has suffered from doubtful management and is already stretched to capacity ("You can"t even get an office there", moans one producer). Its present owner, a local steel company, is keen to sell but talks with a Canadian institution have been thorny, not least because the Czech government holds a golden share. Should the Canadian deal fall through, Stillking says it would consider a bid of its own.

The abortion debate has raged since 1973, when the Supreme Court gave abortion constitutional protection, but the basic law of the land has proved immutable . Abortion is legal, and it"s going to remain legal for a long time. Laws often alter attitudes, inducing people to accept things—such as racial integration—they once rejected. But sometimes, attitudes move in the opposite direction, as people see the consequences of the change. That"s the case with abortion. The news that the abortion rate has fallen to its lowest level in 30 years elicits various explanations, from increased use of contraceptives to lack of access to abortion clinics. But maybe the chief reason is that the great majority of Americans, even many who see themselves as pro-choice, are deeply uncomfortable with it. In 1992, a Gallup/Newsweek poll found 34 percent of Americans thought abortion "should be legal under any circumstances," with 13 percent saying it should always be illegal. Last year, only 26 percent said it should always be allowed, with 18 percent saying it should never be permitted. Sentiments are even more negative among the group that might place the highest value on being able to escape an unwanted pregnancy: young people. In 2003, Gallup found, one of every three kids from age 13 to 17 said abortion should be illegal in all circumstances. More revealing yet is that 72 percent said abortion is "morally wrong". The report on abortion rates from the Guttmacher Institute suggests that the evolution of attitudes has transformed behavior. Since 1990, the number of abortions has dropped from 1. 61 million to 1. 21 million. The abortion rate among women of childbearing age has declined by 29 percent. Those changes could be the result of other factors, such as more use of contraception: If fewer women get pregnant, fewer will resort to abortion. But the shift is equally marked among women who do get pregnant. In 1990, 30. 4 percent of pregnancies ended in abortion. Last year, the figure was 22. 4 percent. Pro-choice groups say women are having fewer abortions only because abortion clinics are growing scarcer. But abortion clinics may be growing scarcer because of a decline in demand for their services and a public opinion climate that has gotten more inhospitable. This growing aversion to abortion may be traced to better information. When the Supreme Court legalized abortion in 1973, most people had little understanding of fetal development. But the proliferation of ultrasound images from the womb, combined with the dissemination of facts by pro-life groups, has lifted the veil. The prevailing view used to be: Abortion may be evil, but it" s necessary. Increasingly, the sentiment is: Abortion may be necessary, but it"s evil.
