Paragraph: After nearly disappearing in the United States, the bloodsucking pests have made a comeback in recent years, quickly infesting apartment buildings and stubbornly resisting common insecticides. The city of New York alone spends as much as $40 million a year in bedbug control. A study of bedbug genetics presented on Tuesday at the American Society of Tropical Medicine and Hygiene meeting in Philadelphia now suggests why. A team of entomologists led by Coby Schal and Ed Vargo of North Carolina State University studied the genes of bedbugs infesting three multistory apartment buildings in North Carolina and New Jersey and found very low genetic diversity meaning most of them were very close relatives. They were so close in fact that the team suspects it may have taken just one or two founder insects to start an entire infestation. "We find that bedbug infestations basically start from a very small number of individuals," Schal said in a telephone interview. "A single mated female bedbug starts the infestation. She gives rise to offspring and those offspring mate with each other and with their mother," he said. "This is different from many animals," he said, mostly because close inbreeding can result in genetic deformities, adding, "In humans, it is taboo." But he said there are some animals that can withstand such close inbreeding without experiencing detrimental effects including cockroaches. Schal said this may be a trait of insects that have evolved an association with humans and rely on them to get from place to place. Typically this happens when humans bring infested furniture into their homes, and he warns people to inspect second-hand furniture carefully. "There is a myth out there that bedbugs get transported on people," Schal said. Unlike ticks, the wingless, reddish-brown insects stay attached to people for a blood meal for just 5 to 10 minutes, he said. "The chances that a person is carrying bedbugs on them is quite low." According to the U.S. Centers for Disease Control and Prevention, bedbugs do not carry disease, but their bites can cause severe itching and a whole lot of anxiety. Schal said his findings are not likely to lead to new insecticides for bedbugs, but they do underscore the need to move fast once bedbugs are detected. "If you don't deal with them early they can spread thorough a building very quickly," he said. Claim: All in the family: Inbreeding key to bedbug spread.

Ex Output:
Inbreeding may be the secret to the bedbug's success, U.S. researchers said on Tuesday.

Paragraph: KTWO-AM reports Carbon County School District No. 2 canceled classes Thursday at the elementary schools in Hanna, Elk Mountain and Medicine Bow, as well as the high school in Hanna. Classes will resume Monday after the campuses are disinfected. Kim Deti, a spokeswoman for the Wyoming Department of Health, says meningitis has not yet been confirmed and there is no public health threat. Superintendent Jim Copeland says student involved attends Hanna Elementary, and the other schools were closed as a precaution. The child has since been hospitalized. Meningitis is an infection of the membranes surrounding the brain and spinal cord. ___ This story has been updated to correct that meningitis has not been confirmed. ___ Information from: KTWO-AM, http://www.k2radio.com/ Claim: 4 Wyoming schools close after possible meningitis case.

Ex Output:
A school district in southern Wyoming has closed four of its campuses over fears that a fourth-grade student might have contracted bacterial meningitis.

Paragraph: Speaking to reporters aboard the plane returning to Rome from his trip to Asia, Francis renewed a call for a total ban on nuclear weapons, including their possession for the purpose of deterrence. Francis said declarations on the immorality of the use or possession of nuclear weapons would be incorporated in the Church's universal catechism, a compilation of Catholic teachings and rules. The pope comforted victims of the 2011 Fukushima disaster on Monday in Tokyo and noted a call by Japan's Catholic bishops to abolish nuclear power outright. Around 18,000 people died or were classified as missing after the so-called Triple Disaster, when a massive earthquake set off a tsunami - in some places 30 meters high - destroying a wide swathe of Japan's northeastern coast and triggering a nuclear meltdown at the plant. "The use of nuclear energy is at the limit (of safety) because we still have not managed to achieve total security," Francis said. "In my personal opinion, I would not use nuclear energy until there is total security. There is not enough security to guarantee that there will not be a disaster," Francis added. Francis said assertions that nuclear accidents were rare were insufficient because effects of radiation are felt for decades on people and the environment, such as in the area around the Chernobyl reactor in Ukraine which was crippled by a meltdown in 1986. Francis, who wrote a major encyclical in 2015 on protection of the environment and the effects of global warming, said humanity had gone beyond the limit in violating nature. As examples, he listed the overuse of pesticides and dispensing growth hormones to animals destined for human consumption. "The (need for the) protection of the environment has gotten to the point where it is either now or never," he said. Without naming countries, Francis accused states of practicing 'armament hypocrisy', saying nations of Christian tradition "speak of peace but live off weapons. This is called hypocrisy". Francis said the United Nations does much good around the world but criticized the system that gives veto power to only a few nations in the Security Council. "Without meaning any offence to anyone, think of the (UN) Security Council: if here is a problem with weapons and everybody votes in favor of avoiding a bellicose action ... and one with veto power votes no, everything stops," he said. The Security Council has five permanent members with veto power - the United States, Russia, Britain, France and China. "I have heard people say that the United Nations should move forward and give up the right of veto of some nations ... It would be beautiful if everyone had the same right," Francis said. Claim: Nuclear energy needs greater safety guarantees, pope says.

Ex Output:
Pope Francis, who met victims of the Fukushima nuclear disaster while in Japan, said on Tuesday that nuclear energy should not be used until there are ironclad guarantees that it is safe for people and the environment.
