Sitting with strangers isn't always a success; getting stuck with someone boring is never a joy, and a bad date can infect the entire table. But unlike a dinner party, a shared table allows you to order what you want, and there's no obligation to talk to the person next to you. Getting to know your neighbors, however, is often part of the fun. Those at such tables tend to be more sociable, like DiGangi and Natt-Irom. At Buddakan that night, the interaction between groups started with food ("Oh, what's that?" as a plate of shaken...
Another strategy is to ambush the bacteria with an unlikely ally: viruses. Vincent Fischetti at Rockefeller University is enlisting the help of bacteriophages, viruses that infect only bacterial cells, leaving human ones alone. They hijack the bacterium's genetic machinery and within minutes start to pump out hundreds of copies of themselves. When enough progeny build up inside the cell, the phages produce an enzyme that chews through the cell wall, causing it to explode with the force of a popping champagne cork and spew out the viral intruders...
...make matters worse, there are plenty of other weapons in the cybercriminal's arsenal. It's also possible, for example, to pilfer confidential data from secure networks by mounting Trojan e-mail attacks. These infect a PC by e-mail, using a program that runs undetected in the background. Free to perform tasks usually reserved for the system's owner, the invader can remotely swipe passwords, upload documents and transmit new attacks. In a report published in 2005, Britain's government-backed National Infrastructure Security Co-ordination Centre released details of a series of Trojan e-mail attacks...
When news broke that a Georgia man had potentially infected dozens of fellow plane passengers, it sent a shudder through the global-health system. Now he's in isolation, with an armed guard outside his hospital door, and other passengers have been told to get tested. Just as there's no way to stop infected birds from migrating or dangerous viruses from mutating, the only way to stop a disease like this from spreading is to keep the carrier away from anyone he might infect. "We depend on a covenant of trust," said Dr. Martin Cetron of the Centers...
...lead in fighting cervical cancer and subsidize the vaccination’s costs for women who want it. HPV is a common, sexually-transmitted disease caused by strains of the human papillomavirus group of viruses. The Center for Disease Control estimates that genital strains of HPV will infect over 50 percent of sexually active men and women at some point in their lives. Once someone is infected with the virus, he or she may remain asymptomatic or may develop genital warts. The greatest danger that HPV poses is that it may cause pre-cancerous changes in the cervix, vulva, anus...
