  • First sex determining genes appeared in mammals 180 million years ago

    23 April 2014, 4:07 pm

    The Y chromosome, which distinguishes males from females at the genetic level, appeared some 180 million years ago. It originated twice independently in all mammals. The team of professor Henrik Kaessmann at the Center for Integrative Genomics and the SIB…
  • Too many chefs: Smaller groups exhibit more accurate decision-making

    23 April 2014, 2:30 pm

    The trope that the likelihood of an accurate group decision increases with the abundance of brains involved might not hold up when a collective faces a variety of factors—as often happens in life and nature. Instead, Princeton University researchers report…
  • Picky male black widow spiders prefer well-fed virgins

    23 April 2014, 2:21 pm

    New University of Toronto Scarborough research shows that male black widow spiders prefer their female mates to be well-fed virgins – a rare example of mate preference by male spiders.
  • From liability to viability: Genes on the Y chromosome prove essential for male survival

    23 April 2014, 2:00 pm

    Despite a well-documented history of dramatic genetic decay, the human Y chromosome has over the course of millions of years of evolution managed to preserve a small set of genes that has ensured not only its own survival but also the survival of men.…
