    Germs you carry around

    Like uptowners and downtowners, different bacterial communities hang out on your cell phone and your shoes. Scientists from the Home Microbiome Study swabbed the shoe soles and phones of about 30 reporters (including one from Science News) in February at the AAAS meeting in Vancouver. The researchers found similar bacterial profiles across reporters, including two types normally found in the...

    ANTI-PARTICLE DISCOVERED — Three international teams of scientists, working in the United States, Switzerland and France, have discovered and identified one of the last predicted anti-particles of matter, the anti-Xi-minus. Also known as the anti-cascade-hyperon, the tiny particle of anti-matter exists only for one ten-billionth of a second. Nevertheless, it has been observed, measured and...

    Pondering speedy neutrinos Regarding “Hints of a flaw in special relativity” (SN: 10/22/11, p. 18), there could be a simple explanation for neutrinos being measured as traveling faster than the speed of light in a vacuum. While a vacuum is typically defined as a space entirely devoid of matter, in fact a vacuum is a busy medium with virtual particles continually being created and destroyed....

    Reinventing Discovery: The New Era of Networked Science by Michael Nielsen

    The most common edit to a Wikipedia article changes only a single line of text. The same is true for Linux, the open-source computer operating system: A typical contribution changes just one line of code. Such “microcontributions” are one way to bring more expertise to any enterprise, argues Nielsen, a physicist. And by using such approaches to make all of science open and collaborative —...

    Babel No More: The Search for the World's Most Extraordinary Language Learners by Michael Erard

    Some people speak several languages — lots of people, actually. But imagine understanding 15 or 30. That’s rare company, and Erard finds such people irresistible. He explores the world of “hyperpolyglots,” superlearners who test the upper limits of language abilities.

    The book covers a lot of territory: hypotheses about how specific brain developments might contribute to...
