Phys.org / Adult female bark spiders produce superior and tougher silk than males do
Dragline silk or major ampullate (MA) silk, the part of a spider's web that forms the main frame and spokes, is one of the toughest materials known to science. That is, it can absorb massive amounts of energy from a sudden ...
Phys.org / Record-breaking cosmic explosion challenges astronomers' understanding of gamma-ray bursts
Astronomers at the University of North Carolina at Chapel Hill have helped uncover new clues about the longest-lasting cosmic explosion ever observed, a gamma-ray burst that lasted nearly seven hours. The event, known as ...
Phys.org / Humans rank between meerkats and beavers in monogamy 'league table'
Humans are far closer to meerkats and beavers for levels of exclusive mating than we are to most of our primate cousins, according to a new University of Cambridge study that includes a table ranking monogamy rates in various ...
Phys.org / Earliest botanical art hints at prehistoric mathematical thinking
A new study published in the Journal of World Prehistory reveals that some of humanity's earliest artistic representations of botanical figures were far more than decorative; they were mathematical.
