The scientists ran their experiment on Arabidopsis plants—a go-to species for plant biologists. The control group was germinated and grown at the Kennedy Space Center (A), while the comparative group was housed on the International Space Station (B). For 15 days, researchers took pictures of the plants at six-hour intervals and compared them. Their results surprised even them: the plants in space exhibited the same growth patterns as those on Earth.
The researchers were looking for two specific patterns of root growth: waving and skewing. With waving, the root tips grow back and forth, much like waves. Skewing occurs when a plant’s roots grow at an angle, rather than straight down. Scientists don’t know exactly why these root behaviors occur, but gravity was thought to be the driving force for both.
So much for that theory. This means the potential for fresh food at ISS, if you’re a vegetarian (or even if not). They should be learning how to do weightless hydroponics. Of course, we still don’t know if animals, and particularly humans, can gestate, or how, and that’s true of partial gravities as well. And we’re not likely to until SSI gets funding for its variable-gravity lab.
“The exhibition of the Hemingway cats is integral to the museum’s commercial purpose, and thus, their exhibition affects interstate commerce,” the court said. “For these reasons, Congress has the power to regulate the museum and the exhibition of the Hemingway cats.”
The USDA acted after a visitor complained several years ago about the museum’s care of the cats. The agency wanted the museum to obtain an animal exhibitor’s license; either cage the cats at night, construct a higher fence to contain them, or hire a night watchman to keep an eye on them; tag each cat; and construct “elevated resting surfaces” for animals, according to the opinion.
Can it get more ridiculous? I often say I’m glad that we don’t get all the government that we pay for, but things like this make me wonder if we actually do.
