Cell Phones Cleared of Cancer Risk
A major study published in the Journal of the National Cancer Institute found that cell phones don't trigger cancer. Cell phones beam radiofrequency energy that can penetrate the brain, raising questions about cancers of the head and neck, brain tumors, or leukemia. The latest study tracked nearly half a million cell phone users, including some who'd been using the phones for 20 years. Researchers found no higher cancer rate among them.evince

Gian Lorenzo Bernini
Bernini was the pre-eminent Italian Baroque artist, sculptor, painter, and architect—the arbiter of public taste in 17th century Rome. Among his best-known sculptures, which combine white and colored marbles with bronze and stucco, are the Ecstasy of St. Teresa in the Cornaro Chapel and the David at the Borghese Gallery. Bernini also designed the magnificent bronze baldachin, or canopy, inside St. Peter's Basilica. His portrait appeared on what unit of currency?The Japanese Attack Pearl Harbor
The Imperial Japanese Navy's surprise attack on Pearl Harbor in Oahu, Hawaii, severely damaged or demolished 12 American warships, destroyed 188 aircraft, and killed 2,403 American servicemen and 68 civilians. The following day, the US declared war on Japan. Pearl Harbor is now a national historic landmark; a memorial has been built over the sunken hulk of the USS Arizona. How many Japanese planes reached Oahu on the morning of the attack?Doberman
The Doberman is a breed of domestic dog that is commonly used as a guard dog, watch dog, or police dog. Loyal and intelligent, these dogs are suitable for families with young children. Though Dobermans are born with long tails, they generally undergo docking, a procedure in which the majority of the tail is surgically removed within days of birth. Dobermans were first bred in Germany in the 1890s by Louis Dobermann, a tax collector. What breeds contributed to the dog's gene pool?
