P. starrii is a species of algae in Japan that has three sexes: male, female, and bisexual; the last of which produces both male and female sex cells. In contrast to hermaphroditism, bisexual P. starrii evolve from natural gene expression. These algae arise when they have a bisexual-factor gene, but only in tandem with OTOKOGI, a male-specific gene. Female P. starrii can carry the bisexual factor gene and pass it on to their offspring.

‘Ghostly’ neutrinos provide new path to study protons
In groundbreaking research, an international collaboration of scientists from the University of Rochester have used a beam of neutrinos to measure the size and shape of the protons that make up the nuclei of atoms. This feat, once thought impossible, provides scientists with a new way of looking at the small components of an atom’s nucleus and opens up a wealth of new information about the structure of an atom’s nucleus and the dynamics of the forces that affect neutrino interactions. The researchers solved the challenge of harnessing neutrinos in large numbers by using a neutrino detector containing a target of both hydrogen and carbon atoms, and over nine years of data collection at Fermilab’s accelerator.
