Carlos Castillo-Chavez, Diego Chowell, Sri Krishna, Xiangguo Qiu, and Karen S. Anderson report that the effect of early diagnosis of pre-symptomatic infections is strongly dependent on the effectiveness of isolation of infectious individuals in health-care settings:

“Our results suggest that a strategy that focuses on early diagnosis of high-risk individuals, caregivers, and health-care workers at the pre-symptomatic stage, when combined with public health measures to improve the speed and efficacy of isolation of infectious individuals, can lead to rapid reductions in Ebola transmission.”

André Taylor‘s latest paper on improving carbon nanotube electronics was highlighted by theAmerican Chemical Society’s Chemical & Engineering News. In “Role of HF in Oxygen Removal from Carbon Nanotubes: Implications for High Performance Carbon Electronics,” Dr. Taylor and his team report that hydrogen fluoride plus electric current purifies nanotubes, improves their electronic properties.

Carlos Castillo-Chavez on Ebola in Texas

Carlos Castillo-Chavez of Arizona State University and colleagues recently published “Temporal Variations in the Effective Reproduction Number of the 2014 West Africa Ebola Outbreak” for the National Academy of Engineers. The second edition of Dr. Castillo-Chavez’s book, Mathematical Models in Population Biology and Epidemiology (with Fred Brauer) is now available for purchase online in Mandarin. In September, he and Sergei Suslov were awarded the Leonhard Euler Prize 2014 in Homburg, Germany for their research contributions.


 

EBOLA MATH

Dr. Castillo-Chavez and Randy Atkins of WTOP News discuss how a new mathematical model can assess the growth rate of an Ebola outbreak as it happens.

 

Jason Sello and his colleagues at Brown and MIT will be published in the Proceedings of the National Academy of Sciences this month. The paper is entitled “Crystal structure of Mycobacterium tuberculosis ClpP1P2 suggests a model for peptidase activation by AAA+ partner binding and substrate delivery”. Sello’s co-authors are MIT’s Prof. Robert Sauer (Sello’s MLK faculty host) and Karl R. Schmitza, as well as Brown University’s Daniel W. Carneyb.

The research shows “new details about how a promising new class of antibiotics attacks the bacterium that causes tuberculosis” and “could provide a blueprint for developing drugs aimed at fighting TB.”

MIT News Q&A with Calestous Juma

How can Africa find new ways to spark economic growth? That was the focus of “Africa Rebooted,” a wide-ranging public symposium hosted by the Center for International Studies moderated by Calestous Juma on Sept. 24 at the Whitehead Institute.

MIT News: You have worked with the African Union as a high-level advisor to develop its new 10-year Science, Technology and Innovation Strategy for Africa, which is a focal point of tomorrow’s Starr Forum symposium. What are some of the distinctive features of this roadmap, regarding the contemporary challenges of growth across the continent?

Juma. The key distinctive feature of the strategy is the recognition that Africa cannot sustain economic growth and promote prosperity without significant investments in technological innovation…READ MORE

In his latest piece for Al Jazeera, 2014-15 MLK Visiting Professor Calestous Juma discusses how African universities will become irrelevant if they don’t focus on the role of science and engineering in development.

“To implement the vision, African organisations are exploring partnerships with leading science and technology universities around the world. An example of this is the Forum on Science, Technology and Innovation in Africa that will be host by the Massachusetts Institute of Technology on September 24.”
