Like so many things, the problem is best explained with an analogy. Imagine a car parked in a dark garage (if you’re a mechanic by hobby or trade, make it a computer). Someone hands you keys to the car, a flashlight and a piece of metal that she says belongs to a car similar to…

Energy Scales

Bacteria are tiny. Compared to our cells, they can seem insignificant. There are about ten times more bacteria cells in your gut *right now* than there are human cells in your entire body, but they only make up about 5% of your mass. They’re tiny, but they’re successful – they live in places we can’t,…

Biological manufacturing

Sometimes, when I take a step back and look at the ways that we can manipulate life, I’m astounded. We can breed mice that lack any gene we want. We can also insert new genes, and have them only express in certain types of cells or only at certain times. This is routine. We can…

The Gulf of Mexico has now become the feedstock of several battles, fierce and feeble, in the legal, political and scientific realm. What battles you say? It’s what…

And now, researching microbes in action, I am continually amazed by their diverse habitats and metabolisms. It is remarkable to think how despite the diminutive size of microbes, they…
