With human population numbers increasing, we can expect the demand for food to continue to grow too. This trend suggests we will have to produce more food to meet that demand, or reduce the food waste we currently create. In this article, we discuss how something uncommon to Western nations - eating insects - might be the solution.

3D-printed foods aren't a new thing. Or, rather, they are - but the hype around them is not. Ever since additive manufacturing started to become more popularized, in the early years of the 2010s, many started speculating what it would be able to do with food.

And despite it being so common, we still struggle to fully understand it and treat it. Now virtual reality is helping us do both.

Exoskeletons exist all around us. Animals such as grasshoppers, cockroaches, and lobsters all have them. For them, exoskeletons provide protection and support, among serving other functions. What if we could allow human beings to experience the same benefits, while at the same time increasing their strength, precision, and power?
