Differences: 信息 vs 讯息?
I originally thought the two are the same but after some research, I've reached the following conclusion:

信息 - information (in general)

Example:
大量信息 - a lot of information
毫无信息  - no information,
错误信息  - wrong information
科学信息 - scientific information
互通信息 - mutually sending information = sharing information

讯息 - message; news; information (specific)


讯息是一段独立的沟通内容，由传送者传达给一个或多个对象  - It is an independent piece of communication, which is communicated by the sender to one or more objects )

Example:
一段讯息 - a message
错误讯息  - wrong message
求救讯息 - help message (SOS is a message)
互通讯息 (mutually sending messages = communicating)
A message is a piece of specific information, therefore 一段讯息(a message) is also an information

信 (letter) contains information

讯 (message; news) e.g. 新闻快讯  (express news); 社区简讯 (Community newsletter)

息 (breath) gives a detectable sign = provides information
