We’ve got a list of teen scientists from a variety of fields.
Jack Andraka
Jack Andraka created a biosensor for cancer that he says is 168 times faster, 26, 667 times less expensive and 400 times more sensitive than technology nowadays.
He’s the youngest person to have spoken in front of the Royal Society of Medicine.
Taylor Wilson
Taylor Wilson was the youngest person to achieve nuclear fusion (核聚变). He was inspired by The Radioactive Boy Scout, a novel in which a kid tries and fails to build a nuclear reactor.
Taylor thought he could do better. Long story short, he wanted to build a small nuclear reactor. And he did it at the age of fourteen. He received a Thiel Fellowship, which gave him $100,000 to work on his own research.
Sara Volz
Sara Volz performed experiments in which she grew algae based on their oil output for the purpose of growing them as biofuel (生物燃料). This research is especially important as the world continues to search for a way to lessen our dependence on non-renewable energy. She won the top prize of S100,000 in the Intel Science Talent Search.
Daniel Burd
Plastic usually takes thousands of years to decompose (降解), but this high school student Daniel Burd managed to do it in three months.
In an experiment, he mixed plastic bags and a special kind of dirt together, and found that they did decompose faster. He then performed tests to find the bacteria responsible for decomposing the plastics.
His solution only produces water and small amounts of carbon dioxide. He says it could easily be used elsewhere.
