Tara Adiseshan, 14, of Charlottesville, Virginia; Li Boynton, 17, of Houston; and Olivia Schwob, 16, of Boston were selected from 1,563 young scientists from 56 countries, regions and territories for their commitment to innovation and science. Each received a $50,000 scholarship from the Intel Foundation.

In the webcast, Tara Adiseshan, talks about her project studying the evolutionary ties between nematodes (parasites) and sweat bees. She identified and classified the evolutionary relationships between sweat bees and the nematodes (microscopic worms) that live inside them. Tara was able to prove that because the two have such ecologically intimate relationships, they also have an evolutionary relationship. That is to say, if one species evolves, the other will follow.

Li Boynton developed a biosensor from bioluminescent bacteria (a living organism that gives off light) to detect the presence of contaminants in public water. Li’s biosensor is cheaper and easier to use than current biosensors, and she hopes it can be used in developing countries to reduce water toxicity. Li Boynton on What’s Great About Science:

Olivia Schwob isolated a gene that can be used to improve the intelligence of a worm. The results could help us better understand how humans learn and even prevent, treat and cure mental disabilities in the future.

In addition to the three $50,000 top winners, more than 500 Intel International Science and Engineering Fair participants received scholarships and prizes for their groundbreaking work. Intel awards included 19 “Best of Category” winners who each received a $5,000 Intel scholarship and a new laptop. In total, nearly $4 million is scholarships and awards were provided.

YouTube has great value, in these videos and in many other ways. My belief is that Google is the company best positioned to make profit from these webcasts. There is a great value in webcasts. My belief is Google is smart enough to realize their is a great value today, and in the long term. And Google isn’t afraid to invest in the long term. My guess is they will succeed in making YouTube profitable.

The future really looks bright when you see what high school students from around the world are able to do in science and engineering.

Over the past decade alone, the company has invested more than $1 billion, and its employees have donated more than 2.5 million hours toward improving education in 50 countries. Learn more about the Intel Education Initiative.
