Solar DNA Tests Detect Cancer Without Electricity, Cornell University Study

The power of the sun could spark a medical revolution. A device can diagnose diseases using nothing more than a smartphone, sunlight and a tiny DNA sample. The KS-Detect, built by engineers at Cornell University in New York, will be used to diagnose Kaposi's sarcoma, the AIDS-related cancer that killed Tom Hanks's character in the film Philadelphia. Li Jiang and his colleague David Erickson, are now testing the KS-Detect in Uganda, in partnership with Makarere University in Kampala.
