Enzymatic computing

I'm quoted in a short piece in the New Scientist breaking news section:

"A molecular computer that uses enzymes to perform calculations has been built by researchers in Israel.

Itamar Willner, who constructed the molecular calculator with colleagues at the Hebrew University of Jerusalem in Israel, believes enzyme-powered computers could eventually be implanted into the human body and used to, for example, tailor the release of drugs to a specific person's metabolism."

Turing archive

"The Turing Archive for the History of Computing is a major Internet project... The documents that form the historical record of the development of computing are scattered throughout various archives, libraries and museums around the world. Until now, to study these documents required a knowledge of where to look, and a fistful of air tickets. This Virtual Archive contains digital facsimiles of the documents. The Archive places the history of computing, as told by the original documents, onto your own computer screen.

This site also contains a section on codebreaking and a series of reference articles concerning Turing and his work."

The Mower

The mower stalled, twice; kneeling, I found
A hedgehog jammed up against the blades,
Killed. It had been in the long grass.

I had seen it before, and even fed it, once.
Now I had mauled its unobtrusive world
Unmendably. Burial was no help:

Next morning I got up and it did not.
The first day after a death, the new absence
Is always the same; we should be careful

Of each other, we should be kind
While there is still time.
