For years, armed groups have instilled fear in eastern Democratic Republic of Congo.
Hundreds have been killed, and millions are diplaced in the North Kivu and Ituri provinces.
The president has instructed the army to take charge of the two regions for a month.
Soldiers have been given broad powers to conduct searches, make arrests and ban public gatherings.
So will this be enough to stop the violence?

Forget what you think you know about dark matter. After a 30-year search for a single, as yet unidentified, species of dark matter particle that would make up some 25% of the mass of the universe, physicists are starting to consider novel explanations. Some envision invisible matter hiding within the folds of extra spatial dimensions. Others suggest not one kind of dark matter particle, but numerous species inhabiting a shadow universe. Others still conjecture that dark matter doesn’t exist, and instead propose that the laws of gravity need modification. We’ll bring together leading thinkers on dark matter—the revolutionary and conventional alike—for a distinctly unconventional discussion on the dark universe.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

Paul Andersen explains how populations eventually reach a carrying capacity in logistic growth. He begins with a brief discussion of population size ( N ), growth rate ( r ) and exponential growth. He then explains how density dependent limiting factors eventually decrease the growth rate until a population reaches a carrying capacity ( K ). A mathematical simulation of this process is included along with a brief discussion of r and K selected species.
