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.

Your Brain on Advertisements

Advertisers are always looking to better understand consumers’ preferences and decision making. The application of neuroscience knowledge and techniques to answer market and media research questions is not new but in our digital age, the practice raises new questions about privacy, informed consent, and consumer autonomy in decision making. Dr. Carl Marci, Chief Neuroscientist at Nielsen explores the ethical concerns that arise and explains some of the tools used by advertisers in this growing field.

Can We Talk? Communicating Through the Cancer Journey

25296As our series on cancer continues, we take a look not at the symptoms of the disease but at the way we talk about the disease. The words we choose and the tone we employ can greatly impact the way patients, caregivers, medical professionals, and families move through the cancer journey.

In this unique look at conversations about cancer, professor Wayne Beach of San Diego State University shares audio and video examples of how communication occurs among those affected in the context of cancer diagnosis, treatment, and prognosis. Deborah Mayer, an advanced practice oncology nurse from the University of North Carolina follows with a look at the different meanings of the word “cancer,” the discomfort of difficult conversations, and the challenge of expressing basic fears.

Women in Science

Our recent series, “Women in Science” was so popular, it has been given it’s own subject page!

UCSD-TV wants to acknowledge the accomplishments of women in science, with the hope of nurturing more female scientists and encouraging other women to get involved in this exciting field.

There have been many great women scientists whose discoveries have been undercut based on their gender. For example, Rosalind Franklin remains the unsung hero who played a pivotal role in the discovery of DNA’s double helix structure with her X-ray diffraction images. She was out-shined by Watson and Crick, the two men who took full credit for the discovery.

And Rachel Carson, the author of “Silent Spring,” faced many personal attacks on her intelligence and credibility because she was smart enough to recognize and brave enough to tell about the devastation caused by large chemical companies. These corporations claimed that because she was a woman her facts were not to be trusted.

Although we would like to think that these sort of prejudices have faded from society, it is important to remember heroes like Franklin and Carson to celebrate women’s scientific accomplishments of the past and support women’s future in science.

Exploring Ethics of Drones and Other UAVs

When you hear the word “drone,” what first comes to mind?

Most people usually think of unmanned aerial vehicles (UAVs) operated by the military in order to spy on citizens and drop bombs on unsuspecting targets.

Lucien Miller, CEO of Innov8tive Designs, explains that the first drone, called the Kettering Bug, was flown almost a hundred years ago, in 1918. Early drones like this were essentially torpedoes with wings, unguided aircraft that dropped bombs with little target accuracy.  It was these types of UAVs that have led people to fear the term drone and the destruction associated with them.

But today, drones and UAVs are rapidly gaining commercial popularity as UAV systems are becoming available at prices non-military budgets can afford. Miller says modern UAVs are becoming so small, they can  be purchased for as little as $400. And now their uses extend far beyond covert military operations, such as search and rescue missions, endangered species protection, and infrastructure inspection, just to name a few.

Keith McLellen, CEO of ROV Systems joins the show to discuss the risks that come with the benefits of drones, the biggest concern being an increase in aerial surveillance and an invasion of privacy.

Watch “Drones and Other UAVs: Benefits and Risks – Exploring Ethics” to hear from Miller, McLellen, and retired Commander Bob Osborne, who worked for the LA County Sheriffs department for 38 years, about the life-saving and livelihood-threatening technology of modern drones.
