Science Cabaret: Why don’t bikes fall down?

You can balance a bike with hands on the handlebars. Or off. And, surprising if you haven’t seen it, a bike can balance itself, with no person touching it. When viewed from the back, a bicycle looks like a stick balanced on end. If it tips a little, gravity pulls it down more.

That Emoji You’re Sending Is Open to Interpretation

Science Friday airs on WSQX Fridays from 2-4pm.  

A new study finds that emoji, the tiny graphic images increasingly used in text communications, can be interpreted in a variety of ways. Researchers at the University of Minnesota found that, due to differences in graphic design, certain characters could convey a slightly negative emotion when rendered on one mobile phone platform but a slightly positive emotion when viewed on another platform. And the problem is not just a matter of translating from Apple-ese to Android-ese. Even within one phone system, different users could interpret a single character in a range of ways.
