The Genetic Gamesmanship of a Seven-Sexed Creature What could be better than two types of sexes? For one organism, the answer isn’t three, but seven! And to top it off, these seven sexes aren’t evenly distributed in a population, although researchers have now developed a mathematical model that can accurately estimate the probabilities in this crap-shoot game of sexual determination. Meet Tetrahymena thermophila, which in addition to its seven different sexes—conveniently named I, II, III, IV, V, VI, and VII—has such a complex sex life that it requires an extra nucleus.

Neuroscience: Hardwired for taste : Nature A mouthful of bittersweet chocolate cake with a molten centre can trigger potent memories of pleasure, lust and even love. But all it takes is one bad oyster to make you steer clear of this mollusc for life. Neuroscientists who study taste are just beginning to understand how and why the interaction of a few molecules on your tongue can trigger innate behaviours or intense memories. The sensors in our mouths that detect basic tastes — sweet, salty, bitter, sour and umami, and arguably a few others — are only the start of the story (see 'The finer points of taste', page S2).

PDB Newsletter Biomedical animator Drew Berry ( Walter and Eliza Hall Institute of Medical Research ) is known for his fantastic and detailed depictions of complex biomolecular systems. His award-winning work, which can be viewed online, in television and film, and in museums throughout the world, now appears in new and unusual venues thanks to a collaboration with the musician Björk. Björk's latest project Biophilia manifests her love for music, technology, and nature in many ways: an album, iPad app, touring production (which includes a 24-woman Icelandic choir and a musical Tesla coil), and a music education initiative. How Do Animals Become Zombies? Instant Egghead [Video] It may sound like something straight out of a horror movie, but many animals can come under the zombie-like control of parasites. So what about humans? Scientific American editor Katherine Harmon fills us in on the ghoulish side of Nature.

Scientists unlock chemical processes behind silver-related skin condition Ingesting silver — in antimicrobial health tonics or for extensive medical treatments involving silver — can cause argyria, condition in which the skin turns grayish-blue. Brown researchers have discovered how that happens. The process is similar to developing black-and-white photographs, and it's not just the silver. PROVIDENCE, R.I. [Brown University] — Researchers from Brown University have shown for the first time how ingesting too much silver can cause argyria, a rare condition in which patients’ skin turns a striking shade of grayish blue. “It’s the first conceptual model giving the whole picture of how one develops this condition,” said Robert Hurt, professor of engineering at Brown and part of the research team.
