Bioengineer Shaochen Chen has developed a method of 3D printing live human tissue that could one day be used to heal damaged spinal cords, hearts, and other vital organs. And, because his technology uses stem cells, the transplant tissue can be patient specific. Now, he's using his technique to help researchers Alysson Muotri and Karl Wahlin understand brain and eye development. Series: "Stem Cell Channel" [Health and Medicine] [Science] [Show ID: 34336]

This CARTA symposium focuses on the contributions of scientists and scholars of anthropogeny who live and work in Africa. Himla Soodyall discusses links between the historical and genetic narrative of populations in southern Africa. Berhane Asfaw assesses the claims for the "earliest" homo sapians.

Tony Wynshaw-Boris, MD, PhD describes his lab's efforts to use mouse and IPSC models to find commonalities that give insight into the complex disorder of autism. Series: "Stem Cell Channel" [Health and Medicine] [Science] [Education] [Professional Medical Education] [Show ID: 34977]

Computer science students are getting involved in high-level research projects in the beginning of their college careers thanks to an innovative program at UC San Diego. The Early Research Scholars Program teams students up with professors who have ongoing research projects. Students get guidance from a centralized mentoring team, which helps them with the basic skills needed to conduct research, so their professors can focus on the details of each project. Students conduct research on everything from autonomous cars, to the microbiome, to software verification. The program has been such a success, it is expanding to multiple universities, with plans to keep it growing. Series: "Computer Science Channel" [Science] [Education] [Show ID: 34691]

Cancer becomes highly dangerous when it spreads from its original site to a different vital organ. These secondary tumors called metastases are what kill most patients. Despite hundreds of years of research, it is not understood why, where, and how cancer spreads to organs like the brain. Lawrence Livermore Lab scientist describes how they bring together cancer biology, 3D printing and material science, to understand and hopefully prevent metastases in the future.

High school student Christopher Caligiuri teams up with renowned stem cell researcher Alysson Muotri to build a robot that interprets signals from lab-grown mini-brains. Series: "Stem Cell Channel" [Science] [Show ID: 34270]

From the viewpoint of a community leader who made the journey from Compton to a University of California professorship, Dr. Gentry Patrick considers the difference between an open door and true access. Series: "Career Channel" [Public Affairs] [Business] [Education] [Show ID: 34908]

Top scientists are growing miniature brains and retinas from stem cells in their labs, and connecting them with 3D printed tissue. The team is hoping to gain new insight into the earliest stages of brain and eye development, in order to cure a whole host of diseases.

Collapsing ice shelves and calving of large icebergs in Greenland and Antarctica have recently become major drivers of sea level rise. The rapidity of these changes has come as a surprise, revealing major gaps in our understanding of how ice sheets respond to a changing climate. To a large extent, these gaps are due to the lack of measurements from the marine edge of glaciers - the Achilles' heel of glaciers. For over a decade, since the glaciers in Greenland began their retreat, Fiammetta Straneo and her group at Scripps Institution of Oceanography have been probing the edge of massive calving glaciers in iceberg-choked fjords in Greenland using helicopters, icebreakers, fishing vessels, and autonomous vehicles. The understanding gained through these measurements is being used in models aimed at improving sea-level rise predictions. Series: "Jeffrey B.
