Tierney Leaves NYT Op-Ed Page

From today’s column:

    Whatever they do the next two years, I won’t be here to kick them around. This is my last column on the Op-Ed page. I’ve enjoyed the past couple of years in Washington, but one election cycle is enough. I’m returning full time to the subject and the city closest to my heart: science and New York. I’ll be writing a column and a blog for the Science Times section.
