Doesn’t the phrase “playing hooky” suggest that “hooky” is some kind of game? And if so, what are the rules? How do you win? Well, some might argue that just skipping out on school is enough of a win (although that explanation will get you after-school detention for sure). But it turns out that hooky really does have rules, and you probably already know them—you just don’t recognize the name. That’s because hooky comes from the Dutch word hoekje, which what you call the game “hide-and-seek” in the Netherlands. The children of Dutch settlers played this in the American colonies in the 17th century, but it wasn’t until the 19th century, though, that teachers and parents became the unwilling participants on the “finding” end of the game.
In your personal interactions, there’s a good chance you enjoy spending time with warm personalities, or that you worry if a special relationship starts to grow cold. What you might not realize, however, is that those temperature words are not just metaphorical. Researchers in multiple studies have found, for example, that not only are lonely people more likely to report being cold, but that coldness can actually increase feelings of loneliness. On the other hand, warmth increases our feelings of personal engagement. Contact with something warm, like a mug of fresh coffee or a heating pad, helped to soothe painful sad memories, promote positive impressions about other people, and even increase acts of generosity and self-sacrifice. So if your steamy romance is starting to get a chill, maybe you just need to turn up the thermostat.
Better, actually. In 1998, a team of researchers developed a plant growth chamber for the mid-deck of the space shuttle. This chamber would provide a miniature rose with the appropriate temperature, humidity, light, and nutrients during space flight. With all the ideal conditions replicated, the rose grew during its journey in space. Once it fully bloomed, researchers analyzed the scent molecules taken from the astronaut blossom and found that this particular rose had a much stronger scent than others of its kind. The reason? Flowers produce a variety of aromas in order to attract the preferences of their pollinators. These aromas are carried in the plant’s essential oils and are strongly affected by the environment. Note to self: ask for a bouquet of a dozen space roses next Valentine’s Day.
From Alice’s whackadoo tea party host, to the phrase “mad as a hatter,” hatters and their sanity seem to be getting a bad rap. The imagery, however, is rooted in some truth. From the 1700s through the early 1900s, mercuric nitrate was a commonly used compound in hat making. The result after many years of hatting? Mercury poisoning. Symptoms included tremors and extreme irritability, which led to the “mad as a hatter” expression. Talk about an occupational hazard.
Despite the masculine mythological associations with Mars, when it comes to actually going there, it might make sense to send an all-female crew. Research dating back over 50 years suggests various reasons why women would be better suited for such long-distance voyages: they have generally stronger hearts, can better withstand vibrations and radiation exposure, and can cope better than men in prolonged isolation. But the best evidence comes from more recent terrestrial simulations of a Mars mission: women expend—and therefore need—far fewer calories than men. What’s so out-of-this-world about that? Simple: fewer calories needed for an all-female crew would mean less food in the payload, equaling huge savings in the mission budget. We’re talking a grocery budget reduction of millions of dollars. So an all-female mission to the red planet may be a hard sell, but it’s really just hard science and savings.
