Small droplets, presumably of spider-produced glue used to make the web sticky, adorn two of the strands preserved in amber, another sign that the ancient web maker probably was an orb weaver, says Grimaldi.
Regardless of its lineage, that spider apparently was successful--it had snagged a wasp, a fly, and a mite in its web. Those insects represent the three insect groups most commonly captured by today's orb-web spiders, Grimaldi notes.
MaSp2 appears in the spider glands that generate silk for the orb web's radial threads, and Flag protein is found in the glands that spin the sticky threads, says Garb.

Unlike video conferencing, a forerunner in the field, web conferencing typically services many users at once.
Currently, almost half of college campuses (45 percent) have some type of digital delivery system; a category that includes both video and web conferencing, according to this year's College Technology Review, published by Market Data Retrieval.
Web conferencing use has extended beyond the classroom, though.
