What usually works for me when I'm trying to learn something new:
- I write down or retell what I have just read. From my experience the ability to reproduce what you have just read with your own words extremely increase probability that you will be able to do this later.
- I try to build some kind of system from the new information: A depends on B, B depends on C etc. Sometimes I draw it with diagrams, but most of the time explicit conclusion of what types of things and connections between them was mentioned in an article is more than enough.
- I try to connect the new knowledge to my experience. I realize that this may not work if you need to memorize something like Maxwell's equations, but it's still possible to build links to what you already know OR ask right questions and learn the missing pieces that help you to build a bridge to what you already know.
So, you may improve your habits of how you consume new information to improve your memory.
If I need to remember something like shopping list I just write it down in notes and don't worry.
