Sleeping helps us to consolidate our procedural memories. This Canadian team managed to get people to go to sleep inside an fMRI scanner. They observed how the brain actually stores away memories.
This online paper also gives a great insight into the peer review process. If you scroll down, you can read the exchange between the editor of the journal and the author, which shows how peer review has improved the work prior to publication.
Network-wide reorganization of procedural memory during NREM sleep revealed by fMRI
Lucid dreams are the experience of being conscious while dreaming. Most of us can only remember our dreams when we wake up. Many people achieve lucidity for a moment or two before waking up. But some people regularly have lucid dreams, in which the world around them seems tangible and real, and they are “awake”, and aware that they are dreaming.
Ursula Voss at the Goethe University Frankfurt has discovered a way to use electrical brain stimulation to induce lucid dreams. Kristoffer Appel at Osnasbrück University is now able to communicate with lucid dreamers inside their dreams. This might one day lead to new therapies for anxiety disorders.
One participant looked around his dream for something that might convey signals from outside. He was in a bus terminal, and spotted a ticket machine. Soon, it began to beep.
The article also contains instructions on how to achieve lucid dreams yourself.

Multi tasking is not actual multi tasking. It is switching attention from one task to another very quickly. Our brains are bad at doing this, and the more we do it the less well we perform. It is better to concentrate on one thing at a time. This book explains why, and gives practical strategies based on sound scientific psychology that will help you to concentrate better and to remember more.
It explains why we find decisions harder if there are too many choices, and how to tackle that problem. It gives practical advice on how not to forget things, how not to run out of time, and how to use logic to make tough decisions, and not to be swayed by irrational emotions.
It also puts forward some ideas for education. What is the point of learning stuff when we can just google everything? The book explores what we should be learning, when everything is just a click away.
Really readable and packed with excellent (and commendably scientific) background psychology.
