The SETI Institute awarded a new education grant through its Support Technology, Innovation, Development and Education (STRIDE) program. Space Science for Youth in South Africa is a professional development program for Girl Guides South Africa (GGSA) staff and volunteers and is additionally funded by The Center for Radio Astronomy and Technologies, Rhodes University. The project will leverage the SETI Institute’s experience developed through Reaching for the Stars: NASA Science for Girl Scouts which developed space science badges for Girl Scouts aged 5-18 and provided training for Girl Scout volunteers and organizers. SETI Institute Director of Education Pamela Harman will lead Space Science for Girls in South Africa as PI, with Jessica Henricks as Co-I.
“This STRIDE award leverages our expertise to bring space science activities and career awareness to GGSA,” said Harman. GGSA aims to empower girls and women to reach their full potential and gives girls the confidence, skills and aspirations to advocate for change and make an impact in the world.”
Developed and delivered by the SETI Institute, this 2.5 day in-person training in July 2025 will equip a carefully selected group of GGSA leaders with knowledge, tools, experience, and resources to expand engaging and inclusive space science education for girls ages 4.5 - 18. The leaders will not only be prepared to deliver space science programs directly, but, more importantly, to train the GGSA’s adult volunteer leaders who serve GGSA’s 20,000 members in urban and rural areas.
The evolutionary success of our species may have hinged on minute changes to our brain biochemistry after we diverged from the lineage leading to Neanderthals and Denisovans about half a million years ago
Two of these tiny changes that set modern humans apart from Neanderthals and Denisovans affect the stability and genetic expression of the enzyme adenylosuccinate lyase, or ADSL. This enzyme is involved in the biosynthesis of purine, one of the fundamental building blocks of DNA, RNA, and other important biomolecules. In a study to be published in PNAS, researchers from the Okinawa Institute of Science and Technology (OIST), Japan and the Max Plank Institute for Evolutionary Anthropology, Germany have discovered that these changes may play an important role in our behavior, contributing new pieces to the great puzzle of who we humans are and where we come from. “Through our study, we have gotten clues into the functional consequences of some of the molecular changes that set modern humans apart from our ancestors,” says first author Dr. Xiang-Chun Ju of the Human Evolutionary Genomics Unit at OIST.
