Lactose molecular structure - Sweet Side of Chemistry
One of milk’s two sugars, lactose is not digestible in those lacking sufficient levels of lactase, which allows the body to metabolize that sugar. Certain parts of the world are reported to have higher incidences of lactose intolerance....

How Did You Get Here?! (Unexpected Ways Species Travel the World)
Sometimes, species end up in places we wouldn't expect, like when the same or very similar species end up on opposite parts of the globe. It's called disjunct distribution, and here are 6 ways that it can happen.

Liquid Nitrogen Demos
We look at how different materials change when they are exposed to liquid nitrogen. Flowers become frozen and stiff and the petals snap. A banana hardens and is strong enough to be used as a hammer and a squash ball becomes very brittle...

Elements vs Alloys
We compare melting points of lead and tin to the melting point of their alloy, solder. By timing how long it takes samples of each to melt, we discover that the melting point of solder is actually lower than those of both lead and tin....
