mating induces sexual inhibition in female jumping spiders




marpissa muscosa, female. credit: wikipedia/cc by-sa 4.0after mating for the first time, most females of an australian jumping spider are unreceptive to courtship by other males, and this sexual inhibition is immediate and often lasts for the rest of their lives, according to a study published octob...



party discipline for jumping genes




jumping genes, transposons, are part of the genome of most organisms, aggregated into families and can damage the genome by jumping. how hosts suppress the jumping is well investigated. why they still can jump has hardly been understood so far. researchers from vetmeduni vienna investigated for the ...

timing is everything: researchers describe genetic clockwork in germ cell develo




the nematode c. elegans is a true organizational talent: the tiny life forms, just one millimetre long, live for only two to three weeks, with sexual maturity lasting only four days. they nevertheless manage to generate over 300 offspring during this brief period. for this ambitious development prog...

scientists study jumping spiders to create agile robots




the results aren't entirely what scientists expected. it's well-known that spiders use hydraulic pressure to stretch their legs, but it's now clear they don't need that power to jump. also, the jumping strategy changes depending on how far they're traveling and whether or not there's a change in att...
