Kgnu - How On Earth

We talk with astronomer Travis Metcalfe about finding the oldest known planetary system in the Galaxy, and what it means about the formation of planets, the possibilities of extraterrestrial life, and how does one actually find planets around other stars? Headlines include switches in the man-made biological organisms that could possibly be used for bioterrorism, and the finding that chronic malaria infection in migrant great reed warblers  damages telomeres, shortening life in both the adult bird and its offspring.
