Neurotransmitter Molecules Neurotransmitters can be broadly split into two groups – the ‘classical’, small molecule neurotransmitters and the relatively larger neuropeptide neurotransmitters. Within the category of small molecule neurotransmitters, the biogenic amines (dopamine, noradrenaline, serotonin and histamine) are often referred to as a discrete group because of their similarity in terms of their chemical properties.

Or install an RFID-enabled deadbolt on your front door and an RFID reader in your car and you won’t need to carry your keys around anymore.
How did life originate? How did life originate? Living things (even ancient organisms like bacteria) are enormously complex. However, all this complexity did not leap fully-formed from the primordial soup. Instead life almost certainly originated in a series of small steps, each building upon the complexity that evolved previously: Simple organic molecules were formed.
