Francium is a radioactive chemical element which is classified among the alkaline earth metals on the periodic table. It is extremely unstable, with a very short half life â approximately 20 minutes â and, as a result, it has few applications outside the realm of scientific research. The bulk of the world's francium is synthesized in labs; it only appears in nature in very small trace amounts, and it is an extremely rare element.
Massive marlin caught off Hawaii coast. A fisherman from Hawaii reeled in giant blue marlin weighing in at 1,368 pounds. CNN affiliate KITV reports.
(The angler holds a commercial-fishing license and was fishing for tuna and billfish to sell at the Hilo fish market.) But the catch is no less impressive, considering that many captains in Kona-whose waters attract the world's largest Pacific blue marlin-were staring to wonder whether the world record was still within reach.
