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 into the biodiversity of the world’s oceans as a relatively new resource for natural product drug discovery. Jensen is at the Center for Marine Biotechnology and Biomedicine at Scripps Institution of Oceanography, UC San Diego.

Is immigration an overall benefit, or burden to society? That’s was the central question posed at the 2019 Arthur N. Rupe debate at UC Santa Barbara. Rubén Rumbaut, Distinguished Professor of Sociology at UC Irvine, takes the position that immigration is not only good, but necessary for the success of the United States. Taking the stance that immigration needs to be scaled back and tightly controlled is Mark Krikorian, Executive Director of the Center for Immigration Studies, a controversial organization that has been designated an anti-immigrant hate group by the Southern Poverty Law Center.
The participants began by laying out their visions for the hallmarks of good immigration policy. Rumbaut leans heavily on the ideas that the population of the United States is aging, fewer children are being born, and our pension and social security systems will fall into crisis without an influx of new workers. Thus, he argues immigration is necessary to prop up those systems, strengthen the labor force, and repopulate shrinking towns across the country. Krikorian’s central idea is the polar opposite. He argues the United States is in good shape, and has no need for new immigration. Therefore, he says immigration policy should seek to have a net zero impact on the economy. He proposes updating the system to only accept immediate family members of current US citizens, and set the bar for skilled immigration to “Einstein” levels, meaning only people at the top of their fields.
Both debaters address several aspects of immigration policy, from big picture concepts like measuring success, to details such as how many people from any given group should be granted citizenship each year. While their differences of opinion are clear throughout the debate, they do find agreement on one issue: the current long-term population of undocumented immigrants in the United States should be granted amnesty.
With a topic as complex and divisive as immigration, it is not surprising to see more disagreement than agreement. But, finding some common ground is essential if any real progress is to be made. Whatever your stance, this debate provides some insight into the other side of the argument.

Genetic counselors do more than interpret lab results. They can guide you through pre-pregnancy planning, help facilitate discussions about family history, and so much more. With so much genetic information available to expectant parents, it is important to have a resource who can not only collect data but help you understand the results.
Dr. Julia Cormano sits down with genetic counselors Christina Brock and Andrea Procko to find out how they support patients throughout pregnancy.

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 arose in Africa.
Given these facts, it is not surprising that the strong emphasis of anthropogeny is on the continent of Africa with wide-ranging studies including genetic, paleontological, archeological, primatological, climatological, sociocultural and more.
This CARTA symposium focuses on the contributions of scientists and scholars of anthropogeny who live and work in Africa.

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 as they seek to understand the ecological implications of changing sea ice conditions.
They are also preparing to participate in the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) Expedition, an unprecedented multi-national effort to study the high Arctic across a complete seasonal cycle.
