In an amusing but pretty important new study, a group from Harvard found that caffeine and other stimulants do not help sleep-deprived participants make better decisions when gambling. The researchers kept people up for nearly two days, giving them the Iowa Gambling Test after each day (which apparently assesses one's ability to make decisions in a casino-like environment). Caffeine (a whopping 600 mg), dextroamphetamine, and modafinil failed to reverse the negative cognitive effects of sleep deprivation. More evidence that there's no sub for sleep.
