This week I asked my editor at the New York Times if I needed to make a disclosure of possible conflict of interest. The trouble is that I have a tapeworm named after me: Acanthobothrium zimmeri.

The reason for the question was the topic of my column: the dire threat that parasites now face. A massive study of parasites around the world shows that climate change could drive as many as 1 in 3 species extinct. I worry that Acanthobothrium zimmeri, which infects a tropical skate, will wink out of existence. My editor didn’t see the need for a disclosure. But I figured that you, dear reader, should know.

Climate Change Threatens the World’s Parasites (That’s Not Good)

Animals around the world are on the move. So are their parasites.

Recently, scientists carried out the first large-scale study of what climate change may do to the world’s much-loathed parasites. The team came to a startling conclusion: as many as one in three parasite species may face extinction in the next century.

As global warming raises the planet’s temperature, the researchers found, many species will lose territory in which to survive. Some of their hosts will be lost, too.

It was a sold-out night on Wednesday at Caveat, the new New York science-themed venue that’s hosting my live series, “What is Life?” this fall.

I talked to a philosopher and an astrobiologist about how they define life, bringing out some props to figure out where they stand, life-wise: some lichen from my yard, a wind-up toy, a vial of viruses, and a rusty nail.

Sara Imari Walker of Arizona State University (in the photo) told the audience that I was talking about life as a thing, whereas she thought of it as a process. I took an applause-based survey, and discovered that they agreed. Continue reading “Friday’s Elk, September 8, 2017” →

Let’s Not Lose Our Minds

I was asked to give the keynote talk at “Science, Journalism, and Democracy: Grappling With A New Reality” at Rockefeller University on September 6, 2017 (video). This is what I said.

We’re here at this meeting to talk about science, journalism, and democracy. So let me begin by telling you about a newspaper article on a scientific experiment, an experiment that would end up having a major influence on government policy on a vital issue.

The vital issue was food. The experiment was carried out on wheat. Some varieties of wheat are known as spring wheat. They’re planted in the spring and grow soon afterwards. Winter wheat, on the other hand, is planted in the fall but does not produce its flowers till the spring. Winter wheat has the advantage of a much bigger yield. But there’s a catch.

Hot Spots in a Freezing Ocean Offer Lessons in Climate Change

Climate change will dramatically alter life in the oceans, scientists say, but there’s so much still to learn about marine ecosystems that it’s hard to know exactly how.

On Thursday, researchers with the British Antarctic Survey offered a glimpse of that future with the results of an unusual study years in the making.

The scientists heated a patch of the sea floor off the coast of Antarctica and tracked the effects on a few local species. Some animals responded by doubling their growth, stunning the researchers.
