I've always kind of been interested in bacteria high school senior kriti lal turned that passion for bacteria into a potentially award-winning intel science fair project I made a novel water treatment system to inexpensively remove arsenic from water this novel system uses a bacteria that I genetically engineer it and it also uses a bioreactor that I designed and built her system costs around eight dollars to build from basic supplies she hopes to help the 137 million people affected by arsenic polluted water main component is the bacteria in the jar which does the real magic which is converting the arsenite to the arsenate she's one of 40 finalists from the nearly 2,000 competitors in Intel Science Talent Search this year finalists projects range from cybersecurity to detecting parasites and blood samples a project created by 18 year old tunay tandon take the slide put it underneath the smartphone and the lens attachment you know take a picture on the camera send to the server the server analyzes it and within a couple of seconds you get an output with sort of a preliminary blood report tandon says the report could detect blood disorders like sickle cell anemia and the presence of parasites indicating a tropical disease like malaria or chagas the tricky part was teaching the computer to make a diagnosis retrain the machine learning algorithms in order to identify the different types of parasites which he did by showing it images of parasites and blood cells whether tendon and law wina top prize or not both students hope their projects will end up saving lives in San Francisco I'm Kara Tsuboi cnet.com for CBS News
