Discovered: 150 billion tons of glaciers melt each year, the fourth warmest January recorded, a rehab app, female fertility changes the way men speak, the benefits of a normal name.

• A rehab app? They have dubbed it the oh-so-original iHeal. And iHeal will incorporate "biosensors," which will measure "arousal" levels. "When the software detects an increased stress or arousal level, it asks the user to annotate events by inputting information about their perceived level of stress, drug cravings, and current activities," explains the study. "iHeal's ultimate goal is to identify, in real-time, drug cravings and deliver personalized, multimedia drug prevention interventions precisely at the moment of greatest need." This is one of those things that sounds good in theory, but we imagine won't work too well in real life. Drug addiction is probably strong enough to out will a computer program, unless the app involves some sort of shock therapy. [Journal of Medical Toxicology]

• Female fertility makes men talk different. Romantic partners who spend a lot of time together tend to talk alike, unless the woman happens to be ovulating and the man wants to implant himself into her body, finds a new study. Weird, right? That a woman's internal, biological goings-on can have such a profound effect on a man's speech pattern. We wonder what it has to do with reproduction, though. Perhaps it's sexier than hearing an echo of oneself, drawing the couple together? Just a guess. [PLoS ONE]
