  21. Book Review: The Natural Navigator: A Watchful Explorer’s Guide to a Nearly Forgotten Skill by Tristan Gooley

    Before navigation was a science, it was an art — a craft that relied on observing nature’s subtle clues and then deducing one’s location or the best route to reach a destination. Besides obvious directional clues such as the rising sun or Polaris, the North Star, there are innumerable more subtle signposts. In the Northern […]

  22. Book Review: Kraken: The Curious, Exciting, and Slightly Disturbing Science of Squid by Wendy Williams

    The great sea beast, with slimy tentacles and a penchant for dragging sailors down into the inky depths, is a common literary figure. And Williams isn’t shy about diving into those myths. She launches her survey of cephalopods, a group that includes squid, octopuses and cuttlefish, with a quote from Pirates of the Caribbean and […]

  23. Japan crisis may have little effect on U.S. energy policy

    Whatever the ultimate repercussions of the Fukushima Daiichi nuclear plant accident in Japan (see Page 6), the crisis raises questions over the role nuclear power should play as an energy source. Michael Levi, head of the energy security and climate change program at the Council on Foreign Relations in New York City, spoke to reporters […]

An experiment in California aims to see if blue […]

  26. Big Fishing Yields Small Fish

    Sharks, billfish, cod, tuna and other fish-eating fish — the sea’s equivalents to lions on the Serengeti — dominated the marine world as recently as four decades ago. They culled sick, lame and old animals and kept populations of marine herbivores in check, preventing marine analogs of antelopes from overgrazing their environment. A net of […]

  27. Letters

    Water at the start, and later “Liquid acquisition” (SN: 1/15/11, p. 26) discusses two new models about how Earth got its water. But the two models are not mutually exclusive. Indeed, I wonder if perhaps two (or more) sources of water may be the only way to match all of the observed isotopic abundances. Is […]

  28. Science Past from the issue of April 8, 1961

    REMAKE VENUS ‘WEATHER’ — Man can land on the mystery planet Venus after making its air suitable for humans.

The primitive algae would remove the carbon dioxide believed to poison the air on Venus for humans. The result […]
