26 gru 2020 · The spider experiment by the US space agency NASA is a lesson in the frustrating failures and happy accidents that sometimes lead to unexpected research findings. The question was relatively simple: on Earth, spiders build asymmetrical webs with the center displaced towards the upper edge.
14 gru 2020 · Now, a study of orb spiders (Trichonephila clavipes) in space has revealed that these smart arachnids can orientate themselves with light when there is no gravity to tell them which way is 'up'. Scientists have conducted myriad spider gravity experiments over the decades.
study houses the two spiders in separate habitats and includes chambers for their food supply of fruit flies. Artificial light simulates day and nighttime, as well as temperature and humidity...
26 maj 2011 · Humans have taken spiders into space more than once to study the importance of gravity to their web-building. What originally began as a somewhat unsuccessful PR experiment for high school students has yielded the surprising insight that light plays a larger role in arachnid orientation than previously thought.
14 gru 2020 · These researchers raised a couple of baby spiders to try out this experiment, and sent some up into space while others remained on Earth. Two spiders were observed for two months while they built webs in zero gravity – they were photographed every five minutes.
10 gru 2020 · Before long, webs built by the spiders grew haphazard, as the two arachnauts got in each other’s way. Fruit flies grown as food for the spiders in space also reacted to their unusual...
