Ape Jokes, Vagus Nerve Hopes and a Thriller Planet

By Laura Helmuth

One of many issues I get pleasure from most about Scientific American is studying about how scientists do their work—the inspirations, the questions, the insights, the collaborations, the “hmm, that’s strange” moments. Anthropologist Erica Cartmill recounts how she got here to review the evolutionary origins of joking. We people are all simply nice apes, regardless of how fancy we gown up, and she or he finds that younger orangutans and chimps play the identical sorts of tips and peekaboo video games that we do.

One other factor I admire about Scientific American is how our writers distinguish between hope and hype.

Analysis on the vagus nerve is at an fascinating level proper now. It’s probably the most me­andering nerve within the human physique, connecting the mind with most of our inner organs. A full-spread graphic by Mesa Schumacher exhibits simply how elaborate its affect is. Charlatans with devices to promote will declare that stimulating the nerve can remedy no matter ails you. That’s not true … however a rising physique of proof suggests the vagus nerve is an effective candidate for treating a spread of well being circumstances. Creator Jena Pincott outlines what we all know, what we don’t and what all of it means.

We must always know quickly whether or not a hypothetical distant planet is orbiting on the fringe of our photo voltaic system. Planet 9 (additionally referred to as Planet X), if it’s actually there, is 5 to 10 occasions the mass of Earth and has been distorting the paths of smaller objects. Volcanologist and science author Robin George Andrews tracks the proof and the rising enthusiasm amongst some astronomers that we’ll quickly have a ninth planet to switch poor Pluto. (Considered one of these astronomers is the one who knocked Pluto out of the planetary pantheon and is hoping for atonement.)
