New edition: NASA, It's Not A Plastic Wrapper on Mars.
NASA has assessed a bright object on Mars (note 1) as plastic wrapper,
but the object shows remnants of a neuron (note 2) and blood vessels
How could an Earthly plastic wrapper show a neuron fossil?
Note 2: Neurons of Earthly squids can be as large as 5,000 microns
across. See
