Sharks navigate oceans using magnetic and electrical senses
UC Davis scientist Peter Klimley tracks hammerhead sharks in the Gulf of California to test if they follow magnetic field variations on the ocean floor. Scripps Oceanography geologist Peter Lonsdale notes local crustal magnets create deviations that may guide sharks, while Adrianus Kalmijn cites electroreceptors on shark snouts as part of a dual navigation system.

Andean Condors to Aid California Condor Recovery Plan
Wildlife biologists plan a field trial using Andean condors at Hopper Mountain to test reintroduction methods for the California condor. Ten to twenty young birds, all female and raised in zoos, will be released in late July or August, then gradually given more freedom as they search for food.
