Why would a bionic submarine sink if it blew up?

Why do mosquitoes suck blood?
In addition to the heat of summer nights, perhaps the biggest headache is the mosquitoes that fly around above our heads. This group of small things will take advantage of our sleep to land on our body, a full meal, and then fly away.

How our brains cope with speaking more than one language
I'm standing in line at my local bakery in Paris, apologising to an incredibly confused shopkeeper. He's just asked how many pastries I would like, and completely inadvertently, I responded in Mandarin instead of French. I'm equally baffled: I'm a dominant English speaker, and haven't used Mandarin properly in years. And yet, here in this most Parisian of settings, it somehow decided to reassert itself.
