Ainissa Ramirez‘s latest piece in the May 2015 issue of Science (Vol. 348, No. 6235):
“I have wanted to be a scientist ever since I was a little girl. I got the idea from a television program called 3-2-1 Contact, where I watched a young African-American girl solve problems. I saw my reflection in her and was transfixed. As time passed and my science career progressed, I saw that reflection less often. Now, years later, after a stint in industry and a negative tenure decision, I’m putting myself out there so that others can see their reflection in me. It’s a precarious path, exposed and vulnerable, but so far the fruits of my journey have exceeded my fears.”
Calestous Juma‘s latest opinion piece in the April 2015 issue of NewAfrican Magazine:
We all know Africa is a continent full of innovation. Now policy makers at all levels must put this strength, along with scientific and technical development, at the centre of economic strategies. Fortunately, the African Union has recently adopted a strategy that seeks to do exactly that.
“The 10-year Science, Technology and Innovation Strategy for Africa (STISA-2024) recently adopted by the African Union (AU) embodies this vision. Its mission is to “accelerate Africa’s transition to an innovation-led, knowledge-based economy.” The strategy is part of the longer-term Agenda 2063 – the AU’s development vision and action plan.”
|Kimani Toussaint led research at the University of Illinois at Urbana-Champaign that demonstrates the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.
To demonstrate its abilities to store sound and audio files, Toussaint and fellow researchers created a musical keyboard or “nano piano,” using the available notes to play “Twinkle, Twinkle, Little Star” (listen below).
“The chip’s dimensions are roughly equivalent to the thickness of human hair,” he says.

Among the judges for this year’s Queen Elizabeth Prize for Engineering was Calestous Juma (pictured with Brian Cox, fellow panelist and professor at University of Manchester ). The Queen Elizabeth Prize, designed to become a “Nobel” for engineering, was set up with cross-party backing and industry support to celebrate innovators with global impact.
The verdict is in: Professor Robert Langer of MIT has won the £1m award for his development of drug-release systems, tissue building and microchip implants.
In connection with Martin Luther King Jr. Day, James Mickens opted to participate in a Reddit Ask Me Anything (AMA) in hopes of answering this question: What is it like to be a person of color in technology and computer science?
“DISCLAIMER,” he writes, “I am not an official spokesperson for MIT, Microsoft, or any other noun besides James Mickens.”
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.”
Terrence Blackman, along with a number of important world renowned mathematicians, is attendingthe AIMS-Stellenbosch University Number Theory Workshop in Cape Town from January 19-23, 2015. The event is hosted by the African Institute of Mathematical Sciences (AIMS) South Africa in Muizenberg.
The goal of this conference, which is being done in collaboration with the Clay Mathematics Institute in the USA, is to give a broad perspective of areas of modern number theory and to highlight some recent advances. This conference is one of the biennial Number Theory meetings which has been held at Stellenbosch University since 1997.
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.
