Mangroves, trees that form forests in the transition between land and sea, provide a habitat for a great diversity of plants and animals worldwide. These coastal ecosystems are invaluable to humans, supplying a number of services essential for our survival. We still do not know how much these ecosystems are worth from an economic perspective – but they are essential from an ecological perspective. Scripps Oceanography’s Octavio Aburto examines mangrove ecosystems and explains why it is vital to put enormous efforts into understanding their value.
“Basic mechanisms in the brain have universal applications and are the road to medical discovery,” says Ralph Greenspan, PhD. He has spent his career studying how genes affect the brain and behavior of the fruit fly. This research has lead to a deeper understanding of mechanisms in the human brain. Hear about his current efforts to develop a full brain scale activity map and the technological and medical breakthroughs emerging from this work.
Rosina Bierbaum, formerly of President Obama’s Council of Advisors on Science and Technology (PCAST) and an Adaptation Fellow at the World Bank, shows how climate change will affect all regions and sectors of the economy, and disproportionately affect the poorest people on the planet. Therefore, improving the resilience, adaptation, and preparedness of communities must be a high priority, equal to that of achieving deep greenhouse gas reductions and rapid development and deployment of innovative technologies, as well as altered planning and management strategies in the coming decades to achieve a sustainable world.

Experts who have addressed cases of extraordinary human cognitive abilities, from memory to music to language, explore what understanding cognitive anomalies can tell us about the development and evolution of uniquely human mental characteristics. Enjoy these fascinating explorations with the series Extraordinary Variations of the Human Mind: Lessons for Anthropogeny. This series is co-sponsored by the Center for Academic Research and Training in Anthropogeny (CARTA) and the Kavli Institute for Brain and Mind (KIBM).

If a neuron has sustained activity over a long period of time (visual stimulus, stress, etc.) it can change the type of neurotransmitter that it makes. This gives our neurons many languages to communicate with and makes our brain more adaptable. Nick Spitzer explains this neurotransmitter switching and how that process impacts our physical abilities, disease processes, and more.
