  In some regions of northern New England, the moose population is down as much 40 percent in the last three years. The cause of this iconic animal's dramatic die-off is not yet known, but researchers' main theory is centered on the parasitic winter tick, and warmer winters may be partly to blame. Hari Sreenivasan reports from New Hampshire.

  The Atomic Bombings of Hiroshima...

  United States Army The Manhattan...

  In August 1945, during the final stage of the Second World War, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki. The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history.
  
  As the war entered its sixth and final year, the Allies had begun to prepare for what was anticipated to be a very costly invasion of the Japanese mainland. This was preceded by an immensely destructive firebombing campaign that obliterated many Japanese cities. The war in Europe had concluded when Nazi Germany signed its instrument of surrender on May 8, 1945, but with the Japanese refusal to accept the Allies' demands for unconditional surrender, the Pacific War dragged on. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on July 26, 1945; this was buttressed with the threat of "prompt and utter destruction".
  
  By August 1945, the Allied Manhattan Project had successfully detonated an atomic device in the New Mexico desert and subsequently produced atomic weapons based on two alternate designs. The 509th Composite Group of the U.S. Army Air Forces was equipped with a Silverplate Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands.
  
  A uranium gun-type atomic bomb (Little Boy) was dropped on Hiroshima on August 6, 1945, followed by a plutonium implosion-type bomb (Fat Man) on the city of Nagasaki on August 9. Little Boy exploded 2,000 feet above Hiroshima in a blast equal to 12-15,000 tons of TNT, destroying five square miles of the city. Within the first two to four months of the bombings, the acute effects of the atomic bombings killed 90,000–166,000 people in Hiroshima and 39,000–80,000 in Nagasaki; roughly half of the deaths in each city occurred on the first day. During the following months, large numbers died from the effect of burns, radiation sickness, and other injuries, compounded by illness and malnutrition. In both cities, most of the dead were civilians, although Hiroshima had a sizable military garrison.
  
  On August 15, just days after the bombing of Nagasaki and the Soviet Union's declaration of war, Japan announced its surrender to the Allies. On September 2, it signed the instrument of surrender, effectively ending World War II. The bombings' role in Japan's surrender and their ethical justification are still debated.
  
  This report describes the effects of the atomic bombs which were dropped on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively. It summarizes all the authentic information that is available on damage to structures, injuries to personnel, morale effect, etc., which can be released at this time without prejudicing the security of the United States.
  
  This report has been compiled by the Manhattan Engineer District of the United States Army under the direction of Major General Leslie R. Groves.

  Race for Nuclear Weapons during...

  Before the Second World War, military conflicts were fought under orthodox conditions, usually termed “conventional warfare,” but several innovations had significantly changed combat, leading inextricably to the race for a nuclear weapon in the 1930s and 1940s. Conflicts had been fought by armies on horseback with guns of varying sophistication since the 16th century, but mechanized warfare and machine guns changed this calculus and set the stage for future combat by the end of World War I. Other sinister changes entered the fray during this conflict, such as chemical weapons like chlorine and mustard gas. The total warfare brought about by World War I and ensuing wars like the Spanish Civil War made the quest for the most powerful weapons somewhat necessary. 
  The Manhattan Project would ultimately yield the “Little Boy” and “Fat Man” bombs that released more than 100 Terajoules of energy at Hiroshima and Nagasaki, but as it turned out, the Axis were not far behind with their own nuclear weapons program. When the Nazis’ quest for a nuclear weapon began in earnest in 1939, no one really had a handle on how important nuclear weapons would prove to war and geopolitics. The attacks on Hiroshima and Nagasaki in August 1945, along with the Cold War-era tests and their accompanying mushroom clouds, would demonstrate the true power and terror of nuclear weapons, but in the late 1930s these bombs were only vaguely being thought through, particularly after the successful first experiment to split the atom by a German scientist. The nuclear age itself was in its infancy, barely 35 years old, but within a few short years the advent of nuclear war loomed over the world and the prospect of the enemy winning the nuclear race kept Allied leaders awake at night.
