“ The moment before they called my name, I was really nervous because the other finalists’ presentations are really good and I thought they would win, ” Kara Fan, 14, who has won America’ s Top Young Scientist, told Yahoo Finance. “ When they announced my name, I was really surprised actually. ”
To win that claim, Fan’ s nano-particle liquid bandage had to surpass the experiments of hundreds of fifth to eighth graders as well as nine other finalists. Fan started developing her liquid bandage in April 2019 to fight the overuse of antibiotics(抗生素).
According to the CDC, roughly 2 million people every year suffer a bacterial infection in the U. S. and about 23, 000 passed away as a result. If left alone, a UN study reported, drug- resistant diseases or the “ superbug” could lead to 10 million deaths across the globe by 2050. When Fan’ s sprayable bandage dries on a person’ s skin, it creates a thin layer that protects the wounded area while breaking the cell wall and killing the bacteria on the skin. After experimenting with copper nitrate(硝酸铜) to fight bacteria, switching to the silver nitrate ended up being the major catalyst (催化剂) to seeing results for her award-winning project.
“ Thousands of years ago, ancient people would use copper and silver to eat with and they would drink water from like copper bowls to kill bacteria, ” Fan explained. “ I found out that it didn’t work. So I used nano silver. ”
Sir Alexander Fleming’ s discovery of penicillin— a type of antibiotic— is Fan’ s favorite scientific discovery. That said, she doesn’ t think humans should rely too heavily on penicillin.
Following her years at Westview High School, Fan hopes to continue her biology track at Stanford University. Along with the ＄ 25, 000 cash prize she won on October 29, becoming Amer-ica’ s Top Young Scientist may help get the private university’ s attention.

With bushfires continuing to swallow different parts of Australia, a local zoo in New South Wales - the state which is the easiest to catch fire - has hit the headlines with a heartwarming story.
Right in the line of a bushfire, the keepers of Mogo Wildlife Park managed to protect all 200 animals from harm after they received evacuation orders, according to reports.
Netizens were quick to react on social media and praised the bravery of the zoo keeper and staffs, as they stayed and managed to protect animals from uncontrolled fires and even sheltered some at their own house.
The 40-year-old zoo keeper, Chad Staples, described the situation as the worst catastrophe, which felt like Armageddon (大决战) here. Luckily, his team had made a precise plan ahead of time by moving everything flammable from the area and the larger animals to safe places.
What’s remarkable is that as the smaller ones needed extra shelter, Staples decided to take them to his own house.
“Right now in my house there are animals of all descriptions in all the different rooms. They are safe and protected … not a single animal lost,” he said.

Last Saturday, my friends and me went to climb the West Mountain. While climb, we enjoyed the sunny weather and a beautiful view. We were very delighted reach the top without much time or effort. Therefore, we found it more difficult to go down, so we went slowly but helped each other when necessary. Though I took care a lot, unfortunately I slip and hurt my leg badly. As the result, I could hardly stand up. One of my friend came to me immediately and carried me on the back till we reached for the foot of the mountain. I was very thankful and felt proudly of having such good friends.
