ICYMI: Spinning synthetic veins and emotion-sensing smartwatch apps

Cotton candy is king of the carnival snacks. Don't @ me.

Today on In Case You Missed It: Researchers from Vanderbilt University are using commercial cotton candy machines to spin synthetic capillaries. Instead of sugar, the machines spin polymer fibers which are then coated in hydrogel and backed. The heat malts the polymer and hardens the hydrogel which then acts as scaffolding for human cell cultures.

We also take a look at an emotion-sensing smartwatch app from MIT. It pairs an iPhone 5S with Samsung's Simband wearable to record and analyze conversational speech, then guess as to the emotion being expressed. And finally, it's TLDR day, where we read you the top headlines of the week that you might have missed while watching American democracy slowly crumble before your eyes.
