Memories can be reactivated during sleep and strengthened in the process,  Northwestern University research suggests. In the Northwestern study, research participants learned how to play two artificially generated musical tunes with well-timed key presses. Then while the participants took a 90-minute nap, the researchers presented one of the tunes that had been practiced, but not the other

We often worry about people who lie awake in the middle of the night - but it could be good for you. Scientists have been saying for 20 years that the eight-hour sleep may be unnatural, and historians increasingly are backing them up.

Caffeine will get you going during the day but could leave you tossing and turning at night  unless you're  a "night owl" to begin with, a new study suggests.

Alpha One Labs co-founder Sean Auriti and a group of like-minded hackers have launched a campaign to build Hackert0wn, a Brooklyn hackerspace the likes of which the world has never seen. As planned, Hackert0wn will be an  entire hacker ecosystem complete with retail shops stocked with spare parts, sleeping pods, a gym that feeds power back into the building, a co-working space, private offices, a cafe with a coffee dispensing robot, a dumpling shop, an aquaponic farm that raises fish and produce for nearby residents and restaurants, and a state-of-the art CNC machine shop. Oh, and all the buildings will be built out of recycled shipping containers.

Millions of people log on to Lumosity daily to flex their brain muscles--and hopefully improve memory, attention and general cognitive performance in the process.  But this brain training site has recently garnered attention for a large-scale survey which found that better brain performance was linked to 7 hours of sleep per night,  aerobic activity 2-3 times per week and a daily cocktail.  While the overall efficacy of brain training remains hotly debated, Michael Scanlon, co-founder and Chief Scientific Officer of Lumos Labs (creator of Lumosity), discusses the findings from the study, what surprised him most and what we can take away from correlational data. 

Having at least six months of expenses provides financial stability, helps you avoid debt with high interest payments, and lowers stress levels. We have a full year of expenses put aside in liquid cash, and it lets me sleep well at night. Emergency funds can actually have a better return on investment than what you see on a bank account. But that doesn't mean I shouldn't still maximize my interest earned, especially as cash is an asset class where you can increase your return without having to take on additional risk (if you stay FDIC-insured or equivalent).
