It will allow us to not only solve difficult tasks, but will also open up exciting areas of research and insights into many fields of science and engineering.” For more information, visit the QCI website at www.cbrc.kaust.edu.sa/qci 

Clean Combustion Workshop and Center Opening The Clean Combustion Research Center (CCRC) will host a workshop from February 17-19, gathering global experts in the area of clean combustion science and technology to showcase current state-of-the-art research in the combustion field. The conference coincides with the official opening of the CCRC, with its Participating in the signing (from left to right) was Fahd bin Abdul Mohsen Al-Rasheed, CEO and Managing Director of Emaar; Abdullatif Al-Othman, Governor and Chairman of SAGIA; Mohammed bin Ibrahim Al-Suwaiyel, President of KACST; and KAUST President Chameau.

At KAUST, we strive to engage in the larger, more influential and impactful innovation network.” To date, KAUST’s pathway for the commercialization of emerging technologies has resulted in over 300 patents filed and the launch of six startups. Current projects include novel solutions relating to solar energy, crowd management, air purification, and clean water. “KAUST is one of the region’s first research universities to build an integrated economic development and technology commercialization program designed around the principles of open innovation. This commitment to the development of entrepreneurial and innovative activities that promote industry collaboration goes hand-in-hand with the vision of GCF,” stated President Chameau.

Discovering New Botanical Heights The KAUST Auditorium lobby had several dozen new residents on display for the WEP 2014 Food and Farming lecture series: fruit bearing and otherwise edible fruit-bearing plants like basil, pansies, Saudi cabbage, and tomatoes, each protruding from its own string-wrapped moss ball. The plants were the product of a Winter Enrichment Program workshop on the practice of kokedama (Japanese for “moss ball”), wherein plants are removed from soil, placed in a mud ball, and surrounded by moss. While the technique dates back several centuries, it has only recently gained popularity outside of Japan, with florists and hobbyists stringing up the mossy orbs to create stunning botanical displays. Natalya Ayers and Fiona Inglis, founders of the UK-based floral company Pyrus, led KAUST community members in the workshop. Reactions were positive, they said, and one KAUST K-12 teacher even plans to introduce the technique to her students. “We’re anticipating a kokedama epidemic on campus,” they added. 

Annual WEP 5K Fun Run Three hundred and forty-one runners, joggers, and walkers, and at least one dog, took part in the WEP 2014 five kilometer run on January 17. While postdoctoral fellow John Pearman’s winning time of 17:20 and other top performances were impressive, many participants were out simply for the fun of it. “The thing I like best about the event is the atmosphere,” said Maha Khalil, a PhD student in KAUST’s Coral Reef Ecology Lab. Nearby, Cabby Tennis, Assistant Principal at KAUST Secondary School, boasted to friends that his dog Chop was the first dog across the finish for the fifth consecutive year.
