    On Feb. 26, the Encyclopedia of Life went live. This site hopes to become the definitive place to find information on every living species—millions and millions of them. The first extensive sets of entries will include fish and members of the potato and tomato families. But more species will be added all the time—offering basic […]

    Regarding this article: A black hole is in a geometrical sense an end to the universe. If we picture the universe using Euclidean geometry, we can imagine going straight out forever. As we approach a black hole, the huge mass changes the geometry so that we also go on forever reaching the surface. We cannot […]

    No cure yet “Growing Up to Prozac: Drug makes new neurons mature faster” (SN: 2/9/08, p. 83) suggests that growth of new brain cells, along with increasing connections, may mediate some of the effect of some SSRIs. Since these new cells would likely persist significantly longer than the drugs themselves, do we see a “cure” […]

    Urgently Wanted—Star Counters

    Through March 8, an organization known as GLOBE at Night is asking for help tallying celestial bodies in the constellation Orion. Designed as a teaching aid, this star-counting program aims to emphasize the loss-of-darkness throughout the globe, a problem which hinders ground-based astronomy. Students, families, and the general public can report their results online by […]

    Evidence of religious head-hunting in ancient Peru, the link between climate and body size, and chest pain tied to obesity.

    I feel that Rachel Ehrenberg was entirely too glib in this article. The description of an ancient Mayan religious ritual as “plucking the hearts from humans and tossing the bodies into the sacred cenote” is disrespectful. I am sure that Science News would never describe any contemporary religious rituals in this manner. Here is hoping […]

    Big evolvers Regarding “Whales Drink Sounds: Hearing may use an ancient path” (SN: 2/9/08, p. 84), I have heard that whales evolved millions of years ago into their present form, including their very large brains. We humans must be relatively recent in terms of our brain structures. Are there data concerning evolutionary development in whales? […]

    New Worlds Atlas

    Keep track of the ever-expanding list of newly discovered planets orbiting distant suns at PlanetQuest 2.0, a revamped Website developed by NASA’s Jet Propulsion Laboratory. It has images, “planet system visualizations,” movies and games that simulate interstellar exploration, and even lets you install a desktop planet counter so that your computer always displays the latest […]

    In reference to this article, scarcity requires society to allocate. Usually markets do a better job than law at allocating efficiently and fairly. Lake Mead could remain full to the brim regardless of pending climate change. The quoted “demand” for 16.6 km3 of Lake Mead water in Southern California and Arizona is not some fixed […]

    Music of sound I was intrigued by the article “Embracing the Dark Side” (SN: 2/2/08, p. 74). It states: “The interaction of gravity, matter, and radiation in the early universe set up acoustic oscillations, cosmic sound waves that left their imprints on the distribution of galaxies across the sky.” Spanish poet Antonio Machado [1875–1939] put […]
