In the November 1943 issue of the journal Genetics, Salvador Luria and Max Delbrück settled a long-running but arcane debate among bacteriologists. The original paper is freely downloadable, and is an amazing document to read today. There’s a delightful innocence in the simplicity of the experimental design, the lengthy explication of the theory behind the work, and the humbleness of the authors’ conclusions. There is no hint that the paper is describing the dawn of molecular biology, a field that would revolutionize humanity’s relationship with nature in ways that are still unfolding 75 years later.

Which contains more information: a five-minute video or a five-page document? As anyone who’s had to pay for excess cellular bandwidth knows, the video contains far more raw data than the text file. That doesn’t mean it has more information, though. What if the video shows someone reading a Dr. Seuss book aloud? Most of the raw data in the video would just be a binary encoding of the speaker’s picture, and a tiny bit of motion around their mouth.

The first time it happened was a hot August day in Maryland, the kind where the nicotine-saturated air inside the tiny, heavily air-conditioned house seemed to vie with the humidity and traffic haze outside, each competing to be more noxious than the other. Late in the afternoon, as I left for my night shift summer job, the steamy transition zone at the front door hit me with a silent thud. Sweat was already starting to bead on my back as I rolled down the windows in my Datsun.

For a modern reader, the most surprising thing about the Galàpagos Islands chapter in Charles Darwin’s Voyage of the Beagle is probably its brevity. Darwin describes the apparently recent volcanic origin of the place, runs through a quick list of its notable species, includes a figure of some finches’ beaks, and then departs for Tahiti. His entire visit to the islands lasted only five weeks, during a voyage of nearly five years.

In 1915, the director of a veterinary hospital in London was trying to grow viruses in his lab. At the time, researchers had a general idea that viruses were some kind of ultra-small microbes. They caused diseases, but could pass through filters fine enough to remove all known bacteria. Unfortunately, nobody had figured out how to culture them. The veterinary hospital director, a physician named F. W. Twort, decided to use a brute-force approach.

As the shoutfest The Onion fittingly dubbed “The War for the White House” staggers towards its storm-soaked climax next Tuesday, there’s one fundamental question that I don’t think has really been answered yet: Why are scientists such raving liberals? We can’t deny that we look that way to the general public. Nature, which is to science what The Wall Street Journal is to investment banking, unabashedly endorsed President Obama for re-election.

A new paper in the journal CHEST presents the case of a toddler who went into respiratory distress after receiving a smear of Vicks VapoRub under her nose. To figure out what happened, the researchers replicated the treatment in ferrets, whose respiratory systems are a good model for humans. The results were not exactly consistent with the Vicks “Breathe free” slogan: [VapoRub] stimulates mucin secretion and [mucociliary transport] in the … inflamed ferret airway.

Recently, I was talking to a researcher about a particular virus, and he mentioned that it has infected us “since fish.” Yes, fish have a time dimension. In two words, he had communicated reams of information: this virus has infected vertebrates ever since the divergence of the common ancestors of fish and mammals - somewhere around 395 million years ago. That implies that all of the species descended from those ancestors should have their own strains of the virus, which will have co-evolved alongside their host species.
