New research shows that [insect / insects] feel pain. The researchers say it isn't the [same / similar] kind of pain that humans feel. The pain that insects feel is a [sensation / sensational] that is like pain. The research was [conduction / conducted] at the University of Sydney in Australia. Professor Greg Neely, co-author of the research report, said: "People don't really think of insects [was / as] feeling any kind of pain, but it's already been [shown / showing] in lots of different invertebrate animals that they can [sense / scents] and avoid dangerous things that we think of as [painful / pained] ." He added: "We knew that insects could sense 'pain' but what we didn't know is that an [injury / injured] could lead to long-lasting hyper-sensitivity...in a [same / similar] way to human patients' experiences."

The researchers looked at how [fruity / fruit] flies reacted to injuries. The scientists [damaged / damaging] one leg on fruit flies and allowed the leg to [heel / heal] . They found that after the leg [fully / full] healed, the flies became more sensitive and tried harder to [project / protect] their legs. Professor Neely said the pain the flies felt stayed in their [remember / memory] and this changed their behaviour. He said: "After the insect is hurt once badly, they are hypersensitive and try to protect themselves for the [lest / rest] of their lives." Neely says he hopes to carry [up / out] more research to better understand how humans feel pain. He said: "We are [hocus pocus / focused] on making new stem cell therapies or drugs that target the underlying cause and stop [paining / pain] for good."
