Could alien blood be toxic to us?

Could alien blood be toxic to us? It may seem like a funny question, but it leads to some interesting scientific places! Not surprisingly, the chances that exo-toxicology (the toxicology of extraterrestrial life forms) becomes a critical issue in our lifetimes is small. But with rapid developments

What's a gene drive?

A gene drive is a radical new way of re-engineering the genetic makeup of an entire species - including harmful insects like the mosquito. But as the technology steams head, fueled by powerful gene editing techniques coming out of synthetic biology like CRISPR Cas9, what are the risks, and how can w
