Last summer, I visited America's first commercial carbon capture plant in Tracy, California. Heirloom Carbon use ground up limestone to capture 1,000 tons of carbon dioxide a year. It's a trial run for a plant planned for Louisiana that could ultimately capture 300,000 tons each year when fully developed. The strangest thing about a technology …
What We Know About Cow Language
Last March, a friend in the Netherlands told me about a researcher nearby who had discovered that cows don’t reply to each other’s ‘moos’ right away. It can take a minute or two for them to respond. They are paying plenty of attention, but their linguistic rhythm is different from ours. This got me intrigued …

The main one is the technology can't do quite what it promises. I have been working in the ethics of biotechnology for a decade and …

In August this year, I was lucky enough to spend three days with American Prairie in Eastern Montana. The temperature climbed to 102 degrees while I was there. Plagues of grasshoppers splattered themselves on the car grille. I went to the prairie to look at the effect of bison on creeks in the mid-summer heat. …
