...energy). This area is referred to as the cell body. The final key structure is the axon. The axon consists of an area called the axon hillock which integrates all the different inputs across the dendrites and, if sufficient to excite the neuron, this region will initiate an electrical impulse, referred to as an action potential. The action potential will travel the length...

...Energy Options, asserts how little physical exertion is required from her role too: “It’s all indoor, mostly computer-based work, or sitting in a lab working with components.” Being an engineer is not necessarily about brawn. [Electronic engineer] Only 11% of professional engineers are female (Engineering UK 2015) 2. To be an engineer, you have to get your hands...

...energy they need to survive by oxidising sulfur. This group hadn’t been considered as organisms that could be viable on Mars but knowing they are capable of surviving under conditions that are very similar to Mars’s means we can ask questions about what might have happened to the chemistry of Mars if microbes like these had once lived there, giving us a potential...

...energy state of electrons increases from the innermost to the outer shells. Fluorescent molecules, also called fluorophores, generally contain rings of carbon atoms (called aromatic rings). These molecules can absorb incoming energy (usually in the form of light). As a result of the absorption of energy, electrons within the molecules change from a resting condition...
