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.
According to Rizzuto, the last blue marlin topping 1,300 pounds was a 1,356-pounder caught aboard Spellbound on June 6, 1992. A 1,400-pound blue was caught aboard Marlin Magic in 1990, but that fish was not caught in accordance with International Game Fish Association rules, and did not qualify as a world record.
