Recently, researchers at the University of Toronto figured out a way with a quick video selfie to accurately measure blood pressure with your smartphone's camera by developing a technology known as transdermal optical imaging (TOI) (透皮光学成像)．
Cameras on smartphones can catch red light reflected from hemoglobin (血红素) under our skin, which permits TOI to visualize and measure blood flow changes. Researchers measured the blood pressure of 1,328 Canadian and Chinese adults by getting twominute videos of their faces on an iPhone. “From the video got by the technology, you can see how the blood flows in different parts of the face and through this flow, you can get a lot of information，” said Kang Lee, lead author of the study.
Lee also helped create an app called Anura, which allows people to try out the TOI software for themselves, giving them the ability to record a 30second video of their face and receive measurements for stress levels and resting heart rate. Lee said more research was needed to make sure that the measurements were as accurate as possible, explaining that the study didn't test people with very dark or very fair skin.
“In order to improve our app to make it usable, particularly for people with hypertension (高血压)，we need to collect a lot of data from them, which is very hard because a lot of them are already taking medicine，” Lee explained. “We cannot tell them not to take medicine, but from time to time, we get participants who don't take medicine so we can get hypertensive people this way. ”
The scientists said there were many potential applications of the technology, including providing health services for those who lived in remote areas.
Adventure is in my blood. And I had been considering how I was going to 1my high school graduation. I didn't just want a small party in the backyard. I started thinking about doing a solo 2somewhere out of the ordinary. I took out maps and drew the 1,500mile route along which I would be 3 from the northernmost point in Norway to the southernmost section of Sweden. When I shared my plans with my dad, he 4 as I thought he would. Because I get my adventurous spirits from him, he was5it.
I had only been away from my home three days now, but there was an inner6 going on inside of me. Part of me was 7 and doubting whether I really could make it. The other part of me was ready to 8to myself and my family that I could do it by myself.
On the road, I met another bicyclist who was quite a bit older than I was. He had started his journey alone by bike at the southern part of Norway and had just finished. I could tell he had a great sense of 9. It encouraged me not to 10.
As I listened to my11 artists on my MP4 player, I pedaled (踩踏板) with my feet. There was 12 around me for miles. 13 ， that wasn't entirely true. There were mosquitoes—millions of them. My arms were so dotted with bites that they looked like a topographical map (地形图). But, however14 it would be, nothing could stop my advance 15the destination. As you know, adventure is in my blood.
Sara Savick remembers one special Easter when she was nine years old. Her parents gave her a baby duckling in a yellow basket.
“Mom said later that she bought the little duck because she felt sorry for it，” recalled Sara. The people at the pet store colored the feathers pink for Easter. Sara named the duck Pinky.
Sara's mother really didn't think the baby duck would survive very long. But to her surprise, Pinky grew and got stronger and stronger. Soon, the little duckling was a healthy, hungry duck with white feathers.
“We fed Pinky oatmeal, cooked and uncooked, and small pieces of vegetables，” said Sara. Pinky lived inside the house with Sara and her family. She specially fancied taking baths with Sara. Everyone treated Pinky as a family member.
But just when everything appeared to be perfect, the night of the “talk” came. Sara's Mom and Dad sat her down, explaining that the best thing for Pinky was to live a normal duck life, with other ducks. It was not natural for ducks to live indoors with a family, her father told her. He added Pinky needed to swim in ponds and do all the same things that ducks in the wild do.
Sara started to cry, knowing what was going to happen. Sara's parents decided to take Pinky to a park, which was two miles away. There was a pond with a lot of other ducks. Pinky would have the chance to live a natural life and Sara could still visit her.
The big day came, Sara and her parents put Pinky in a box and drove to the park. Sara said that Pinky did not look happy; maybe Pinky was convinced that she was a human, not a duck.
