It used to be that many people who studied animal behavior thought dogs were too weird to bother with. We had bred them far away from the “natural” state of animals, so their brain had little insight to offer us.

That’s changed a lot in in the past couple decades. We have transformed wolves into some cognitively remarkable creatures, it turns out, and the diversity of breeds we’ve produced can serve as an unplanned experiment in the genetics of social behavior.

Of course, one of the biggest rules in all science is the more data the better. Which in this case means the more dogs that scientists can study, the more they may be able to discover about them.

All of which is introduction to an article I’ve written in today’s New York Times about a new push to gather Big Data about dogs–and to provide some insights from that data to dog-owners themselves. Check it out!

If you want to know something about how our ancestors came out of the ocean and onto land, there are just two sorts of fish you should get to know really well. One is the lungfish, our closest aquatic relatives, and the other is the coelacanth, our next-closest. Trout, goldfish, salmon–they are all just distant ray-finned cousins. Lungfish and coelacanths, by contrast, have much in common with us, including a few of the bones that would give rise to our legs and arms. And coelacanths are especially fascinating because until the 1930s, scientists believed that they had gone extinct 65 million years ago. Now they turn out to live off the coasts of both Africa and Indonesia.

Which is why I hope you’ll join me Thursday at 11 am ET to participate in a Google Hangout with a panel of scientists to talk about the latest scientific discoveries about this amazing fish. The occasion is the publication of the coelacanth genome last week.

I just learned the sad news that the great biologist François Jacob has died. He won the Nobel Prize for his work in the 1950s that showed how cells switch genes off–the first crucial step to understanding how life can use the genome like a piano, to make a beautiful melody instead of a blaring cacophony.

Jacob was also a wonderful writer, and so I had enormous pleasure mining his memoirs for my book Microcosm: E. coli and the New Science of Life. I hope this passage gives a sense of what he was like–
