A new study of wild chimpanzees shows that the biggest predictor of territorial boundary patrols is the number of males in the group. The more males in the group, the more often they will patrol their territory.
Chimpanzees will sometimes attack and kill their neighbors during the rarely observed boundary patrols, said John Mitani, professor of anthropology at University of Michigan and co-author of the paper "Correlates of Territorial Boundary Patrol Behavior in Wild Chimpanzees," with David Watts of Yale University.
Scientists have known for about 25 years that the patrols and fatal attacks occur, the question has been what accounts for the varying number and frequency of these patrols and attacks.

Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
