An Air National Guard pilot who fired on a New Jersey school during a training exercise was to blame for the incident, but poorly designed controls in the F-16 also played a role, the Air Force concluded Friday.The report, obtained by The Associated Press, also disclosed that there have been three other incidents this year in which an F-16 pilot unintentionally fired during nighttime strafing missions. It did not say where and when the other incidents occurred, but the report noted that, like the New Jersey case, no one was hurt.The report called the Nov. 3 New Jersey incident an unfortunate and unintentional mistake. It said the pilot never intended to strafe the Little Egg Harbor Township Intermediate School and suggested computer software changes to the aircraft control systems to prevent another incident.In an F-16, the same trigger is used to produce a laser marker to

Fitness landscapes are an effective way of showing how well organisms are doing at reproducing. Traditionally, however, these models are static snapshots of processes that often take millennia to unfold. Now, computational biologists have created a video that visualizes these adaptive landscapes over time. Evolutionary biologist Sewall Wright came up with the idea of fitness landscapes back in 1932. His maps displayed reproductive success, or fitness, of individual organisms as a function of genotype a organism genetic constitution or phenotype or organism observable physical characteristics . Traditionally, these maps are shown in two-dimensions, looking something a bit like this: Or this: So, an organism with higher fitness has a higher chance of reproducing, hence the topographical nature of the maps. Populations, therefore, te
