  • Topsy-turvy currents key to removing nitrate from streams
    on March 15, 2018 at 6:07 pm

    More than 500 years ago, Leonardo da Vinci sketched what he called 'la turbolenza,' comparing chaotic swirls atop flowing water to curly human hair. It turns out those patterns influence myriad phenomena, from the drag on an airplane's wings and the formation of Jupiter's red spot to the rustling of tree leaves. […]

  • Female hunting spiders do not respond to chemical signals given out by potential mates, preferring...
    on March 1, 2018 at 3:36 pm

    Unlike many other species, male hunting spiders do not use chemical signals such as sex pheromones to attract a mate. Instead, they make their mark by uniquely exploiting a female hunting spider's interest in food. Research now shows that male hunting spiders wrap morsels of food in their silk and offer these as gifts to prospective mates. […]
