Macinley Butson was just 16 years old when she first had the idea to try and protect women from more — than — necessary radiation during breast cancer treatments—and now, her invention could be a game-changer in the medical field.
Butson, whose father works in medical physics, has always been interested in science. But she only began researching the harmful side effects of radiation treatment after her father discussed his experience with ineffective cancer treatments in his work. Since Butson had also recently lost a relative to breast cancer, she felt inspired to conduct her own research on the subject. She tried to begin her medical research by consulting scientific journals, but she found their academic terms almost impossible to understand.
She then turned to the Internet to find videos that taught how to read scientific journals. As she went deeper in her research, she stumbled upon a key bit of information: copper （铜）has been shown to be effective at protecting skin from radiation. An idea hit this Australian teen as she was viewing a film on medieval wars in her 10th grade history class. When she saw the scaled （鳞片） patterns of the mail （盔甲）,she was inspired to create a wearable protective tool out of copper. She then headed back online and watched videos on how to put together tiny scales. She made her own flexible scale-mail which she now calls SMART: Scale Mail for Radiation Therapy.
When her invention was tested in a laboratory setting, it reduced surface exposure to unnecessary radiation by 75%. And now Butson is working on getting her SMART into clinical settings for use.

(come) from all corners of the Earth every day. If a ship 8. (suspect) to be harboring the plague (瘟疫)，it was sent to 9. offshore quarantine and ordered to wait there for 40 days when those abroad either recovered, or 10. (likely), died. The waiting period gave rise to the term quarantinario, from the Italian word for 40.

____, a year later, I joined a similar trip to the same spot. I obtained __ to bring a remotely operated vehicle (ROV) and a colleague to __ it. We would try to __ the camera.
When we arrived back and set out our search, we __ technical difficulties almost immediately and had to pull the ROV out of water twice. However, on the third try, the ROV caught hold of the camera. As we eventually got the camera up, we __ loudly. I managed to take the memory card out and later __ all 149 photos.
