Why do some people develop addictions and others don’t? Does that provide insight in how to mediate addictive responses and behaviors? Join The Scripps Research Institutes’ Olivier George as he talks about his research and shares insights into how the brain responds to a variety of drugs, both illicit and prescription – as well as alcohol and nicotine – and new directions in developing novel therapies to reduce compulsive drug use and abuse.

Shaping Our Dynamic Microbiomes for Lifelong Health
Our life-spans are ever-increasing, but our health-spans are not, leading to long periods of unpleasant and expensive suffering with chronic conditions. Many of these conditions have recently been linked to the microbiome. We are constantly shaping our microbiomes through the foods we eat, the environments we experience, even the people we live and work with.
Through the American Gut Project, the largest crowdsourced and crowdfunded citizen-science project yet conducted, we now know about the microbiomes of many types of people, from the healthiest to the sickest. Potentially real-time analysis of our microbiomes could guide our daily decisions in a way that optimizes our microbiomes for extending our health-span. Although the potential benefits of such research are clear, what are the risks (e.g., privacy concerns) that need to be identified and addressed?
Rob Knight is Professor of Pediatrics, Bioengineering and Computer Science & Engineering and is Director of the Center for Microbiome Innovation at UC San Diego. He authored “Follow Your Gut: The Enormous Impact of Tiny Microbes” and co-authored “Dirt is Good: The Advantage of Germs for Your Child’s Developing Immune System.” His work combines microbiology, DNA sequencing, ecology and computer science to understand the vast numbers of microbes that inhabit our bodies and our planet. He was recently honored with the 2017 Massry Prize for his microbiome research.

The Persistence of Memory
For La Jolla Symphony & Chorus’ 2018-2019 season, Music Director Steven Schick has chosen an encompassing theme entitled “Lineage: A Memory Project.” As Schick explains,
A critical component to living an ethical life is how we remember, how we create lineage. It answers important questions: Who are we? To what echoes of our history do we resonate and how do we memorialize them? And, most importantly, what do we need to do today so that, in the future, we will be remembered by someone who will recognize herself in her memories of us; who will examine her lineage through our lives and be grateful?
This concept guided Schick when programming the season’s concerts, as he sought to highlight linkages between seemingly disparate composers and styles. The inaugural concert, also titled “Lineage,” is a case in point, as it unites three composers widely separated by era, location, upbringing, native culture, and modality.
The first offering, “Lineage,” is by young Canadian composer Zosha di Castri. According to di Castri the piece was inspired by the memories her Italian immigrant grandparents shared with her as a little girl in Alberta, against which she contrasts the noises and rhythms of her contemporary life. Di Castri invites the listener to dive under the work’s modernist surface to discover the echoes of a vanished era; some effort is required to sift through the shifting textures and impermanent rhythms to reach memory’s deep core, but the rewards are great.
Like di Castri’s composition, Tan Dun’s innovative “Concerto for Water Percussion and Orchestra” evokes the past, in this case the composer’s childhood in rural China. Tan Dun considers the sound of water to be universal and fundamental, even primal, to the human experience; after all, the aqueous environment of the womb is the first sound we hear, and a connection to the Earth’s oceans and waterways is hardwired into mankind’s DNA. Accompanying the sounds of water, as played by three featured percussionists, are the metallic sounds of spiritual rituals and the suggestion of chants conveyed by voice-like effects in the orchestra. All combine to portray a culture that is at once ancient and contemporary, but always rooted in immutable truths.
Composed for Diaghilev’s Ballets Russes, Igor Stravinsky’s beloved “Petrushka” draws upon memories of Stravinsky’s youth, in particular the Shrovetide Fairs popular in rural Russia and the Ukraine. The music tells the story of three puppets whose tangled love affairs and jealousies result in tragedy. Mixed with this narrative are the sounds of festival barkers and fair-goers and traces of Russian folk melodies, all melded together in a style that pointed the way for composers who followed.
Taken together, these three pieces make a strong case that music in all its forms is a most effective means for recognizing and celebrating our diverse lineages.
Feeling the Heat: The Biology of Ocean Warming
The effects of climate change on fauna and flora across the globe are more and more evident – the Pika has changed its range, and may disappear, sea stars have been visited by a withering collapse in population, insects from bark beetles to mosquitoes are inhabiting new territories, bringing disease to humans and destruction to forests. And close to home, the ocean temperature recently hit the highest temperature ever recorded.
As our changing climate provides a natural laboratory for examining how organisms evolve adaptations to environmental extremes, Scripps’ Oceanography’s Ron Burton asks: can evolution keep up with rapid climate change or are most species likely to go extinct as temperatures rise?
Ron shares about the cutting-edge genetic tools he uses to understand how populations of tidepool animals cope with rapid temperature changes and how evolution has shaped those responses across the geographic range of each species.
