FEATURERestoring Natural Capital Courtesy of M. Powell Working for Water in South Africa The sides of the Baviaanskloof ("Baboon Canyon") in South Africa's Eastern Cape Province range from very steep to vertical. Halfway up a 45-degree slope, under the supervision of spirited 19-year-old Abbey-gail Lukas, 10 men and women are planting thick cuttings of a plant locally known as Spekboom (Portulacaria afra) in circles three meters apart.

How First World Scientists Can Reach Out To Third World Colleagues
Eugene Garfield | Oct 30, 1988 | 2 min read
Turn to the “Tools” or “New Products” pages of The Scientist and you will discover splendid state-of-the-art instruments, many of which carry rather hefty price tags. It’s hard not to notice that the cost of doing science has been rising precipitously. The reason? For one, scientific investigations are increasingly more detailed or far-reaching, requiring more complex and powerful instruments. Many universities and companies in the U.S. can afford the latest equip

Centrifuge Improvements Put New Spin On A Laboratory Workhorse
Howard Goldner | Mar 5, 1995 | 7 min read
A true laboratory workhorse, the centrifuge has been an essential part of most biological labs for many years. Using centrifugal force obtained by spinning experimental samples at high revolutions per minute (rpm), the device functions as a preparative method to separate various sample components, within minutes, for further treatment. Ultracentrifugation is an even more powerful technique that is used in analytical studies involving the characterization of and interactions between biological m
Historically Black Colleges Combine Research, Education
Steven Benowitz | Feb 16, 1997 | 9 min read
Sidebar: Information on Minority Access to Research Careers In the United States, there are more than 100 historically black colleges and universities (HBCUs). In the late 1860s, these institutions were designated by the federal government to educate African Americans as a result of a segregated educational system in the South. Science administrators at the majority of these schools view their mission differently from their counterparts at majority U.S. institutions. Rather than focus their eff
