A New Focus for Energy Efficiency

Our planet is experiencing worldwide growth in energy consumption and CO2 emission and is experiencing temperature rise and climate change at an accelerating rate. A new series from the Institute of Energy Efficiency at UC Santa Barbara describes a path to reducing our energy consumption and CO2 emission.

The series kicks off with John Bowers, Director of the Institute of Energy Efficiency and Professor of Electrical and Computer Engineering and Materials, discussing the evolution of photonics and what the future holds for more efficient, higher capacity data centers, which are important for machine learning and data processing.

Fiber optics has transformed our work and, indeed, our lives, by enabling the Internet through low-cost, high-capacity fiber optic transmission. In data centers, fiber optics is replacing electrical cables, thereby allowing for higher and more economical performance.

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 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.

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 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.

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 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.

All About the Brain

Explore the immensity of the human brain, its billions of neurons and trillions of connections, and the research that is helping us understand more about this complex and amazing organ.

Lawrence Livermore National Laboratory’s popular lecture series returns with four new episodes each relating to the brain. The lectures are aimed at a middle and high school level and presented by LLNL scientists in collaboration with high school science teachers. This is a great opportunity to get a look at the cutting-edge science in a friendly and understandable way. Explore the immensity of the human brain, its billions of neurons and trillions of connections, and the research that is helping understand more about this amazing organ.
