From Sea to Pharmacy
The vastness of the ocean is only surpassed by the biodiversity within it; from familiar and unfamiliar mega-fauna, to every microbe and virus inhabiting every corner of the seas – from the deep freeze of the Antarctic to the scorching plumes of volcanic seafloor vents. Paul Jensen describes how he and other researchers are tapping…

We Are All Africans
Svante Pääbo once said, “We are all Africans, either living in Africa or in recent exile from Africa.” It is now abundantly clear that Africa was the “cradle of humanity,” with multiple waves of hominins arising on that continent and spreading across the old world, eventually being effectively displaced by our own species, which also…

Understanding the Arctic Climate System
The Arctic is changing rapidly in response to global climate and economic activity and yet much of it remains unexplored with modern scientific techniques. Jeff Bowman is a biological oceanographer who studies marine microbial communities. In this presentation at the Birch Aquarium at Scripps Institution of Oceanography he describes his group’s work in the Arctic…

3D Printing with Stem Cells
Transplants are expensive and risky, and donor organs are in short supply. Researchers at UC San Diego are working on technology to change all of that. It’s called bioprinting. In simple terms, bioprinting is 3D printing with living tissue. Researcher Shaochen Chen has been perfecting the process in his lab for years. Bioprinting is a…

Brain-Powered Robot
It sounds like the plot of a science fiction movie. Scientists grow brains in a lab and use them to power robots. But, it’s really happening at UC San Diego – to a degree. Stem cell researcher Alysson Muotri has teamed up with a high school student for the groundbreaking project. It’s called the Neurobot,…

What is in the Air We Breathe?
“What we do in my group is we zoom in on the aerosols.” Vicki Grassian and her team look at aerosols at a microscopic level to determine their impact on our health and our climate. Aerosols can be mineral dust and sea spray from the ocean or created by human activity or stem from any…

Glaciers and Sea Level Rise
Using helicopters, icebreakers, fishing vessels, and autonomous surface and underwater vehicles for over a decade, Fiammetta Straneo and her group have been probing the edge of massive calving glaciers in iceberg-choked fjords in Greenland to explore what is the Achille’s heel of glaciers – the marine edge where glaciers meet the sea. Their goal? Collapsing…

Neanderthal Among Us? Science Meets Fiction
What makes us human is a question that not only science asks, but all disciplines of mind from philosophy to religion to sociology and ethics, and even to storytelling and the arts. Tim Disney’s new movie “William” is about a Neanderthal living in the modern world and forces us to ask about humanness and many…

Searching for a Cure for Blindness
There are a number of diseases that can lead to blindness. But, a researcher at UC San Diego thinks there might be one way to cure them all. It’s called endogenous regeneration. Think of a lizard re-growing a lost tail. Zebrafish can do something similar with retinal tissue. Researcher Karl Wahlin says there is evidence…
