The invasive species Carex kobomugi, or Asiatic sand sedge, was first found along the East Coast of the United States at New Jersey’s Island Beach State Park in 1929. The species is aggressive, outcompeting native vegetation and reducing local biodiversity. In many places, land managers have made great efforts to remove it.

Every time a hormone is released from a cell, every time a neurotransmitter leaps across a synapse to relay a message from one neuron to another, the cell must undergo exocytosis. This is the process responsible for transporting cellular contents via lipid-encapsulated vesicles to the cell surface membrane and then incorporating or secreting them through membrane fusion.

If you held a ball up to a mirror, it would produce an image that, if pulled out, would sit perfectly on top of the ball. Yet if you held your right hand up to a mirror, the image produced would be a left hand, which is not identical to the original; a glove for one hand cannot comfortably fit the other. 

Viruses and their hosts are in a eternal game of one-upmanship. If a host cell evolves a way to stop a virus from spreading, the virus will look for a new path. And so on and so forth.
