Global population hit 7.3 billion midway through 2015, an increase of 2 billion since 1990. It will continue to climb steadily, according to forecasters, reaching 8.5 billion in 2030, 9.7 billion in 2050, and 11.2 billion in 2100.

But there is more to the population story than unprecedented numbers.

Numbers continue to stack up against the world’s poorest continent.

Global population levels are expected to increase from a current figure of 7.2 billion to nearly 11 billion by 2100, according to figures released . . . by the U.N. Previously, it was believed the world’s population would peak at around 9.5 billion. Nearly all of this new growth, meanwhile, will occur in Africa, which is expected to quadruple in size.

Pitt, Drexel, and NIH team up to study persistence of Ebola virus in wastewater

EUREKEALERT                                                                                                               Aug. 25, 2015
PITTSBURGH--The historic outbreak of Ebola virus disease in West Africa that began in March 2014 and has killed more than 11,000 people since, has raised new questions about the resilience of the virus and tested scientists' understanding of how to contain it. The latest discovery by a group of microbial risk-assessment and virology researchers suggests that the procedures for disposal of Ebola-contaminated liquid waste might underestimate the virus' ability to survive in wastewater.

Current epidemic response procedures from both the World Health Organization and the Centers for Disease Control and Prevention advise that after a period of days, Ebola-contaminated liquid can be disposed of directly into a sewage system without additional treatment.

However, new data recently published by researchers from the University of Pittsburgh, Drexel University, and the National Institutes of Health indicate that Ebola can survive in detectable concentrations in wastewater for at least a week or longer.
