By now, you've seen the amphibian invariably referred to in the press as "an unfortunate frog" being lifted towards the heavens after it wandered too close to a NASA launch pad in Virginia. But did you know that this frog was not the first to try (and fail) to reach space?
At The Guardian, Jason Goldman writes about the history of frogs in space (or, at least, frogs that were briefly pointed at space), which dates all the way back to September 19, 1959, when the US Air Force attempted to send up two frogs on board a Jupiter AM-23 rocket. Why frogs? Goldman explains:
Frogs were used because their inner ears turn out to be quite a useful model for the human inner ear, and the factors that induce motion sickness in frogs are the same as those for humans and other mammals. In addition to their use as model species, frogs were also logistically valuable thanks to their amphibious nature: preflight surgery could be performed out of water, but the frogs could then be kept in water during the experiment. This was important for two reasons: first, the water cushioned the critters from the vibration that comes when you launch an 18,000kg Scout rocket into space. Second, the water would cycle carbon dioxide and heat away from the frogs, keeping them cool. This was all possible because frogs can breathe through their skin while submerged in the comfortable 60F water.
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
Biologist Nipam Patel and his team at UC Berkeley study how butterflies develop wing shape and color by performing surgery on caterpillars, creating translucent windows in their cocoons.
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
Custom coffee vessels are the perfect piece of office flair, but it’s just a matter of time before your VOTE FOR PEDRO mug will start to lose its relevant wit. Why not have a new one every day, with whatever silly nonsense you want sticking off the sides? You can save big on your novelty […]
The Lightning port has thus far resisted the cruel fate that befell the headphone jack, and despite rumors that it may be disappearing come iPhone 8, for the present and foreseeable future, Lightning cables are a hot commodity for iPhone users. As such, we must make do in this strange time in which long, glorified […]
