Even when they think they have the answer to something, researchers are still cautious about their findings. And this fact  especially applies to the mystery that is the sleeping brain. Sure, we have a measured understanding of sleep cycles thanks to fMRI scans, but we still don’t know why certain things happen. And when it comes to sleep syndromes and phenomena, the mystery deepens precisely because there are no set answers for why the sleeping brain works when it’s healthy.

The higher up you are the lower the air pressure an...

[2] In the IEA's World Energy Outlook 2011 report, "[u]nconventional oil include[d] extra-heavy oil , natural bitumen (oil sands), kerogen oil , liquids and gases arising from chemical processing of natural gas (GTL), coal-to-liquids (CTL) and additives." [3] Defining unconventional...
