Despite continued reports of economic growth in Africa, much of the continent remains wracked by poverty, with roughly one in five citizens saying they frequently lack food, clean water and medical care, according to the largest survey of African citizens.
This suggests the growth is not trickling down to the poorest citizens or that actual growth rates are inflated, said Carolyn Logan, assistant professor of political science at Michigan State University and deputy director of the survey, called the Afrobarometer. (more…)
Researchers have developed a new mathematical model that accurately describes the evolution of ancient empires.
The computer model can predict with 65% accuracy where and when the largest complex societies arose in human history.
The research, which suggests that intense warfare is the evolutionary driver of large complex societies, is published in the journal Proceedings of the National Academy of Sciences (PNAS). It was carried out by researchers from the University of Exeter in collaboration with University of Connecticut and the National Institute for Mathematical and Biological Synthesis (NIMBioS) in the US.

Protecting key regions that comprise just 17 percent of Earth’s land may help preserve more than two-thirds of its plant species, according to a new study by an international team of scientists, including a biologist from North Carolina State University.
The researchers from Duke University, NC State and Microsoft Research used computer algorithms to identify the smallest set of regions worldwide that could contain the largest numbers of plant species. They published their findings in the journal Science. (more…)
Part of the 4Afrika Initiative, the program will offer mentorship, training, university-level education and employment opportunities to aspiring African youth.
LAGOS, Nigeria — Aug. 12, 2013 — In recognition of International Youth Day, Microsoft Corp. Monday introduced the 4Afrika Scholarship program, as part of its 4Afrika Initiative, through which it will provide mentorship, leadership and technical training, certification, university-level education, and employment opportunities for promising African students. Mentorship will be provided by Microsoft employees from around the world, and employment opportunities will include internships and both part-time and full-time jobs within Microsoft, as well as with the company’s more than 10,000 partners across Africa.
Through the company’s 4Afrika Initiative and YouthSpark program, Microsoft has committed to helping millions of Africans get critical skills for entrepreneurship and employability. The 4Afrika Scholarship program is one way the company intends to meet that goal, by helping ensure that promising youth have access to the education, resources and skills they need to succeed, regardless of their financial situations. To help redress gender disparity in higher education in Africa, the company is actively encouraging young women to apply. (more…)
A model of great ape history during the past 15 million years has been fashioned through the study of genetic variation in a large panel of humans, chimpanzees, gorillas and orangutans. The catalog of great ape genetic diversity, the most comprehensive ever, elucidates the evolution and population histories of great apes from Africa and Indonesia. The resource will likely also aid in current and future conservation efforts which strive to preserve natural genetic diversity in populations.
More than 75 scientists and wildlife conservationists from around the world assisted the genetic analysis of 79 wild and captive-born great apes. They represent all six great ape species: chimpanzee, bonobo, Sumatran orangutan, Bornean orangutan, eastern gorilla, and western lowland gorilla, and seven subspecies. Nine human genomes were included in the sampling. (more…)
Fossil-hunting expeditions to Tanzania, Zambia and Antarctica provide new insights
Predecessors to dinosaurs missed the race to fill habitats emptied when nine out of 10 species disappeared during Earth’s largest mass extinction 252 million years ago.
Or did they?
That thinking was based on fossil records from sites in South Africa and southwest Russia.
It turns out, however, that scientists may have been looking in the wrong places. (more…)
The colorful images chronicle the seasonal stirrings of our salty world: Pulses of freshwater gush from the Amazon River’s mouth; an invisible seam divides the salty Arabian Sea from the fresher waters of the Bay of Bengal; a large patch of freshwater appears in the eastern tropical Pacific in the winter. These and other changes in ocean salinity patterns are revealed by the first full year of surface salinity data captured by NASA’s Aquarius instrument.
“With a bit more than a year of data, we are seeing some surprising patterns, especially in the tropics,” said Aquarius Principal Investigator Gary Lagerloef, of Earth & Space Research in Seattle. “We see features evolve rapidly over time.” (more…)
Award-winning journalist, activist, and author Charlayne Hunter-Gault told a packed audience at Yale that lessons learned from the civil rights movement still have relevance for current and future generations.
Hunter-Gault delivered a lecture titled “Social Justice, Equity, and Public Health” during a Branford College master’s tea on Feb. 5. (more…)
