Skeletons in the Closet

I shouldn’t say this. In fact, as someone who covers the field of archaeology for a living, I probably shouldn’t even be thinking this. But I find myself wondering increasingly whether it’s time for some dirt archaeologists to relinquish one of their great pleasures, namely the beloved rite of summer:  field season. I say this [...]

Galápagos Monday: World Within Itself

This is the third installment of a six-week series about my recent trip to the Galápagos. You can read the first post, about tortoises and donkeys, here, and the second, about eerie mounds of black coral, here. If you go to the Galápagos, and even if you go, as I did, in a herd of clumsy American tourists, [...]

What the ‘limits of DNA’ story reveals about the challenges of science journalism in the ‘big data’ age

As a science journalist, I sympathize with book reviewers who wrestle with the question of whether to write negative reviews. It seems a waste of time to write about a dog of a book when there are so many other worthy ones; but readers deserve to know if Oprah is touting a real stinker. On [...]

Fitting In

** The new study, certainly not the last word on DNA, was published last week in The EMBO Journal. The music is Chopin’s Minute Waltz, the subject of another post.

Guest Post: Remembering Horace Judson

In his several books and many articles in magazines and academic journals, Horace Freeland Judson dared to size scientists up, though he wasn’t one. He died on May 6, age 80. He was my teacher and my friend, and I would like to say a few things about his works both to offer tribute and [...]

Our biochemical romance: Osama bin Laden and DNA

Last week, officials said that DNA from multiple family members was used to confirm that its years-long hunt for Osama bin Laden had ended in success. But even as politicians criticized President Obama’s decision not to release photos of the dead bin Laden, nobody questioned the assertion that, thanks to DNA, US officials are “99.9” [...]

My Coffee Problem

On Friday I woke up too early with a splitting headache and chest pain. This was alarming. In the shower, I tried to come up with a list of plausible explanations, but my mind found only one: the four cups of coffee I drank the day before. I wondered, is this how a heart attack [...]
