Science master receives information in varied short format (4)

'varied short format' is the definition.
I know nothing about this answer so I can't tell whether this works.

'science master receives information' is the wordplay.
I cannot really see how this works, but
'science' could be 'sc' and 'sc' is present in the answer.
'master' could be 'm' (common abbreviation eg MA, Master of Art) and 'm' is located in the answer.
'information' could be 'i' (common abbreviation for information) and 'i' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

'in' is the link.

Can you help me to learn more?
