(20%)(A)Malicious software that has infected millions of computers across the globe failed to wreak havoc on Wednesday as some feared, but researchers warned the po

11、werful Conficker worm could still strike. Also known as Downadup or Kido, Conficker turns infected PCs into slaves that respond to commands sent from a remote server that effectively controls an army of computers. The fears of an attack, however, may have been a windfall for anti-virus software make

12、rs, who warned consumers about the worm, industry analysts say. Symantec Corp, McAfee Inc and Trend Micro Inc spend millions of dollars a year on promotional campaigns that warn about threats to personal computers. “A scare like this could make consumers think twice before deciding to let their subs

13、criptions lapse,” said FBR Capital Markets analyst Daniel Ives. The industry had been under pressure because the recession caused some customers to hold off buying new software and others to delay renewing subscriptions. The security industry formed a task force to fight the worm, bringing widesprea

14、d attention that experts said probably scared off the criminals who command the army of slave computers, known as a botnet. Researchers warned the botnets commanders are probably waiting until they are under less scrutiny before they mobilize the network of infected computers. “I never thought it wo

15、uld happen April 1,” said Roger Thompson, chief research officer at AVG, an anti-virus firm. “It might be tomorrow. It might be next week. It might be next month.” Viruses that turn PCs into slaves exploit weaknesses in Microsofts Windows operating system. The Conficker worm is especially tricky bec

16、ause it can evade corporate firewalls by passing from an infected machine onto a USB memory stick, then onto another PC. The Conficker botnet is one of many such networks controlled by syndicates that authorities believe are based in eastern Europe, southeast Asia, China and Latin America. While the

17、 Conficker botnet is still inactive, analysts say millions of machines in other networks are regularly ordered to perform tasks for their masters. The botnets owners often sell the slaves or rent them out, offering services such as credit-card and banking information theft. They can be customized to

18、 perform other tasks, such as knocking down websites and bringing down corporate networks. “ The worst thing is that no one really knows what these things can do. These things can be programed to do anything,” said Mel Morris, CEO of anti-virus company Prevx. Analysts say Conficker garnered unpreced

While estimates vary greatly, researchers say tens of millions of machines are compromised without the knowledge of their owners. Alfred

24、e with tens of millions of machines.(B)The small study of about 140 overweight or obese women showed that those on diets “appropriate” for their genetic makeup lost more weight than those on less appropriate diets, researchers told an American Heart Association meeting. “The potential of using genet

25、ic information to achieve this magnitude of weight loss without pharmaceutical intervention would be important in helping to solve the pervasive problem of excessive weight in our society,” Christopher Gardner at Stanford University in California, who worked on the study, said in a statement. Massac

26、husetts-based Interleukins $149 test looks for mutations in three genes, known as FABP2, PPARG and ADRB2. The company says 39 percent of white Americans have the low-fat genotype, 45 percent have the type that responds best to a diet low in processed carbohydrates and an unlucky 16 percent have gene

27、 mutations that mean they have to watch both fat and processed carbohydrates. The researchers randomly assigned around 140 women to one of four diets the low-carb Atkins diet, the ultra low-fat Ornish diet, the very low-fat LEARN diet or the more balanced Zone diet. Interleukin went back and tested

28、about 100 of the women for their DNA by using a cheek swab and then looked to see if the women on the “right” diets lost more weight. Over a year, people on diets appropriate to their genetic makeup, as determined by the test, lost 5.3 percent of body weight. People on mismatched diets lost 2.3 perc

29、ent, the Stanford researchers told the meeting. Cholesterol levels improved in line with weight loss, they said. The company said the test looks for genes that affect metabolism. “One of the gene variations affects absorption of fats from the intestine,” Ken Koorman, chief scientific officer at Inte

30、rleukin, said in a telephone interview. He said people with that particular mutation absorb more fat from their food and thus should avoid fat if they want to lose weight. Another of the variations affects insulin response the bodys production of insulin to metabolize sugar, he said. Simple carbohyd

31、rates such as sugar and processed flour stimulate people with that particular gene type to store more of the energy as fat. Ten percent to 16 percent of people have both mutations, and must watch both carbs and fat, Kornman said. “What we dont know is if they are on the right diet for their genotype whether it affects satiety or feeling full,” he said. He said the company planned broader studies to ask these questions. Interleukin markets the test under the brand name Inherent Health. It also can test who might best lose weight in response to exercise.42. Weight loss has much to
