It can be assumed, based on convincing false advertisements in the media, that people often believe everything they read, providing that it posses ample supporting evidence and/or examples. When informed that some information in a factual piece has been falsified, subjects will highlight the topics with less information backing them up, and assume them to be false. It can also be assumed that subjects will also accept questionable material as true, as long as there is enough supporting evidence, no matter how absurd the "fact" may seem.
To present a partially true document that is altered with some convincing false information. This Survey group will have as little as ten subjects and as many as twenty-five. Each subject will be given two highlighters; one colour will be for true information and the other will be for false information. If material is questionable, the subject will be asked to underline the information with which ever colour they feel it sways more towards(true/false).
Like an episode from the popular television series, CSI: NY, two high school seniors sought to identify hundreds of specimens that they had collected throughout Manhattan. Their goal? To identify the species by analyzing at a small portion of their DNA using a technique known as "DNA barcoding." As a method for quickly identifying species, DNA barcoding has become increasingly more accepted within the previous six year. The two investigators made a number surprising discoveries using DNA barcoding, including mislabeled food items, and -- most astonishing of all -- the discovery of a species of cockroach that is new to science. The insect, which looks like the American cockroach, Periplaneta americana, a widespread pest in NYC and other large cities, turned out to have a different "DNA barcode" from that species.
"It's genetically distinct from all the other cockroaches in the database," said investigator Brenda Tan. Ms. Tan, a senior at Manhattan's Trinity School, who worked on the project, along with fellow classmate Matt Cost. Professor Stoeckle, a medical doctor who conducts genomic and DNA barcoding research at Rockefeller University, supervised Ms. Tan and Mr. Cost. "[Closely-related] species don't differ [by] more than one percent, [while] this cockroach is four percent different," agreed Professor Mark Stoeckle. "This suggests it is a new species of cockroach."
To conduct this study, Ms. Tan and Mr. Cost collected a total of 217 specimens between November 2008 and March 2009. They rummaged around in supermarkets, streets and in New York apartments, including that of Professor Stoeckle, where they found the new cockroach species.
"The superintendent of the apartment building was surprised when we wanted to save rather than squash the cockroach," remarked Ms. Tan.
After the specimens were collected, they were photographed and labeled before their DNA was isolated and sequenced by scientists at the American Museum of Natural History.
