But studies in rodents and monkeys have shown that in two regions new neurons continue to be created even in adulthood – the hippocampus, which is involved in learning and the formation of new memories, and the olfactory bulb, which processes smell.However, there has been some controversy over whether the same is true for humans.
This is not an indication of a security issue such as a virus or attack.Seventy-one years ago Saturday, a United States B-29 bomber named the "Enola Gay" dropped the atomic bomb "Little Boy" over the Japanese city of Hiroshima.The bomb fell just over 29,000 feet from the plane and detonated 1,900 feet above Shima Hospital, an active medical center with a history dating back to the 18th Century.Nuclear bomb tests carried out during the cold war have had an unexpected benefit.A radioactive carbon isotope expelled by the blasts has been used to date the age of adult human brain cells, providing the first definitive evidence that we generate new brain cells throughout our lives.Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.
Here’s an example using the simplest atom, hydrogen. Carbon-14 is an unstable isotope of carbon that will eventually decay at a known rate to become carbon-12.
Every person alive on the 71st anniversary of those attacks holds in their flesh radioactive remnants of the nuclear era — a period centered in the early decades of Cold War when nuclear nations conducted atmospheric tests of ever-larger bombs.
No that Carbon-14 won't hurt you, no, it's not giving you lung or bone cancer... Lucky for kids today, they aren't sucking as much of that stuff as we did..... is the Bomb Effect?
The bomb effect refers to the phenomenon that produced artificial radiocarbon in the atmosphere due to nuclear bombs.
Nuclear weapons testing brought about a reaction that simulated atmospheric production of carbon 14 in unnatural quantities.
The study also provides the first model of the dynamics of the process, showing that the regeneration of neurons does not drop off with age as sharply as expected.
