kenneth foster, bioengineering department of the university of pennsylvania. thank you. >> nice to be with you. >> in 2010, a book came out. it was called "disconnect," and it was written by deborah davis. you said you went from three cell phones to no cell phones. why? >> i did not give up completely, but contrary to what mr. foster has told you, a number of health agencies have issued warnings about cell phones. i learned the british government had a review group cell phone that cell phones in 2000, and i was stunned, to learn that they recommended back then that teenagers be limited in their use of cell phones. >> when you look at the nih study and the slide showing increased brain glucose activity, what is your conclusion? >> i think it is a stunning piece of work and i agree with mr. foster. the exposures were quite low. that is why we need to be concerned. what i have done in my book is to show that dr volkow's study was not a breakthrough in terms of showing the effects on the brain, but it was one of the most elegant pieces of work ever done. the reaso

kenneth foster, bioengineering department at the university of pennsylvania. thank you for being on "the communicators." >> guest: nice to be with you. >> host: in 2010 a book came outside, it was called "disconnect," and it was britain -- written by deborah davis. in your presentation about your book, you said you went from three cell phones to no cell phones. is that correct? and why? >> guest: no, i didn't go to none, i still have one, but i certainly gave up my three because i began to learn that contemporary to what mr. foster just told you, a number of health agencies have issued warnings about cell phones, some as long ago as ten years. the british government had a review grouped that that looked at cell phones in the year 2

countries, india, tanzania and nepal through our program at johns hopkins called the center for bioengineeringation and design and we went to these countries to get a better idea of the factors and criteria that we needed to develop technologies for developing countries so they are adopted and used in the countries. so we started about in the fall, and each of the tests are at different stages whether they are just changing the threshold levels or whether they are more early stage. we expect a couple of them will be going out in the end of this year and next year as well. >> yeah, the protein screening test which is the furthest developed and if all of the testing this summer goes well, we hope to start mass production at the end of this year or early next year. >> all right. great. thank you so much. sean and mary in baltimore, we appreciate it, and we will be watching to see the progress of your innovation. >> thank you. >> thank you very much. >> for more on these folk goes to our blog at cnn.com/ali. you want to know what inp know vative ideas we will look at tomorrow? tune in and see and
