question:
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.
answer:
Inbreeding may be the secret to the bedbug’s success, U.S. researchers said on Tuesday.


question:
Paragraph: "It is less surprising that neither story discussed costs, given that so few stories do. But sample costs could have been obtained by calling any of the numerous medical marijuana outlets in states where it is legal. Both stories did a decent job of quantifying the benefits.This story provided more details, though, including the differences in patient experiences between the three different concentrations of marijuana. It also repeated this important bit of information: ""There was also no difference in the quality of life or mood scores that participants reported when they were on any of the four treatments."" The story also does a great job of pointing out that the treatment duration of five days in each dosage phase is too short to judge utility for chronic pain, which is a long-term affliction. Neither story actually quantified the harms, but they both noted there were side effects. This story did a better job, though, by noting that the only dose that seemed to work also seemed to produce the most side effects and by raising the issue of long-term safety concerns. It also was the only story to answer the question that readers surely would have when reading about an illegal narcotic being used as medicine. Did these patients feel high as a result? This story says that most did not. Because of the additional information and context, the rating here is satisfactory. This story, unlike the competing WebMD piece, establishes in the first sentence — even in the first three words — that this was ""a small study."" It then discusses the limitations of the study at several points. The second sentence says, ""The pain reduction was ""modest"" – less than 1 point on an 11-point scale for the strongest marijuana – and patients reported no overall difference in their quality of life based on what they smoked."" The writer elegantly and succinctly described the study design — a complex randomized cross-over trial with double blinding and delved into an important feature of the study, that the subjects in retrospect may have been able to detect during which phase of their experience they inhaled placebo versus the most potent drug. This story avoids disease mongering, and, in fact, goes beyond that to note how few people actually suffer from the type of chronic pain that was the subject of the study: ""About 1 to 2 percent of adults in the U.S."" The story quotes two outside experts, one of whom is completely independent from the study and the journal, Dr Andrea Hohmann. Beyond that, we would bet that the reporter spent more time interviewing Dr. Mark Ware, the lead researcher, or at least asked tougher questions. Because Ware is more measured in this story than in the WebMD story. He even goes so far as to say, ""What about long-term safety issues?"" he asked. ""These need to be considered before the drug becomes prescribable."" As with the WebMD story, it would have been nice to see who funded the research. Unlike the WebMD story, this one did not point out the conflicts of interest of Dr. Henry McQuay. This story talks about a range of treatment options and even has the study’s lead author suggesting, that ""these patients should also be getting behavioral and physical therapy."" Strangely, neither story we reviewed pointed out that marijuana is illegal in most states and in Canada, where the study took place. The story could have, at a minimum, mentioned which states have medical marijuana laws or talked about whether any other countries currently allow cannabis to be sold in pill form the way it was used in this study. The story alludes to the fact that this study ""supports a limited number of trials that have suggested marijuana may be helpful for people suffering from chronic pain,"" indicating that the treatment is not very novel at all. It would have been nice to see more context around that. The WebMD story provides a little more information in this regard. If the news release is to be believed, ""This is the first trial to be conducted where patients have been allowed to smoke cannabis at home and to monitor their responses, daily"". That could have been made clear. The story goes well beyond the release. Here’s the release." Claim: Pot may provide some chronic pain relief: study
answer:
The story did a great job evaluating the evidence, providing outside voices, discussing alternatives to marijuana smoking, and presenting both the benefits and the potential harms. It could have done a better job discussing possible costs, availability and conflicts of interest. From the headline to the last sentence, this report avoided overstatement of the applicability of the potential benefit and used clear incisive language that left the reader with a good understanding of the study and its implications. This topic lends itself to jokey, pun-filled writing, but this story played it straight. Chronic pain can ruin lives, and a breakthrough with an alternative approach would be important news. As this story makes clear, until some larger studies with fewer limitations are undertaken, we are far from the point where marijuana can be considered a safe and effective treatment for chronic pain.


question:
Paragraph: A 34-year-old woman from Loudi city in the central province of Hunan confessed to poisoning the yoghurt drink before delivering to the students, Xinhua said on Saturday. It said the woman was suspected to be suffering from a mental disorder. Three children were in serious condition but their lives were not in danger, Xinhua said. Investigations were going on. There have been several attacks on schools in China in recent years while at the same time, food safety has become a contentious issue with a rising number of food-poisoning cases due in part to lax safety standards at small factories. Claim: Nineteen students sick in China from poisoned yoghurt.
answer:

Nineteen primary school children in China have been hospitalized after drinking yoghurt said to be laced with rat poison and herbicide, the Xinhua state news said.
