(Newser) – An eye-opening little stat to ponder over your morning joe: Harvard researchers say drinking two to four cups of coffee a day appears to cut the risk of suicide by a whopping 50%.

(Click for that 2011 story.) But the 50% stat is nonetheless "striking," she adds. Meanwhile, Grist picks up on a story about a vending machine at a South African airport that uses facial recognition software to detect yawns and distribute free coffee. (It's a publicity stunt for a local roaster, but still kind of interesting and/or creepy.)
