The Evolution of SARS-CoV-2

In the United States, privacy is considered a fundamental right. Yet today our activities are followed to a degree unfathomable not long ago by way of cell phones, online behaviors, and more. As genomic technologies continue to expand, another avenue now exists by which we may potentially be scrutinized: DNA sequence. Our genetic information contains our most private details, but we leave it everywhere and share the sequence closely with dozens or even hundreds of relatives. Laura Rivard, PhD, professor of biology at the University of San Diego, discusses ways in which our DNA may "escape" from our control, what can actually be done with the sequence, and whether there is cause for concern.

Your Genetic Privacy in the Big Data Era - Exploring Ethics

What defines consciousness? Can it develop in a petri dish? Patricia Churchland reviews the current state of brain organoid research and shares her views on how conciseness and physical structures within the brain intersect. She also cautions the media on the tendency to "over hype" new research advances. Series: "Stem Cell Channel" [Show ID: 35247]

Sensory Implications of Brain Organoids with Patricia Churchland

The study of brain organoids is leading to a better understanding of human development and potential therapies for neurological disorders. Yet when people hear the phrase "brain in a dish" it instantly brings to mind the stuff of science fiction - labs full of sentient brains thinking and plotting. Alysson Muotri explains why these organoids should not called "brains in a dish" and how they are being used to explain human processes previously inaccessible to study. While underscoring scientific value of these organoids, he also raises the question of what ethical questions demand an answer as the technology improves.

There are only two Northern White Rhinos left on the planet. How can we reverse extinction to save them and use the lessons learned to help other endangered species? Marisa L. Korody, PhD of the San Diego Zoo Institute for Conservation Research shares how scientists are using the latest in stem cell technology for a genetic rescue.

Stem Cells to the Rescue: Saving the Northern White Rhino from Extinction

Jennifer Doudna, co-discoverer of CRISPR-Cas9, discusses how genome editing with CRISPR technology is transforming biology. CRISPR-Cas9, an RNA-guided enzyme with remarkable abilities to recognize and cleave DNA, operates by mechanisms that both explain its biological function and provide insights into technology development. Doudna covers research into this amazing family of proteins: where they came from, how they work and how CAS-9-based technologies are revolutionizing research, biomedicine and agriculture.

Marius Wernig, MD, PhD, discusses how his lab has worked to convert non-neuronal cell types (lymphocytes, pluripotent stem cells, fibroblasts, hepatocytes, lymphocytes) to neurons. The lab is now working on identifying the molecular mechanisms underlying induced lineage fate changes, the phenotypic consequences of disease-causing mutations in human neurons and other neural lineages.

Usted tiene la opción de someterse a exámenes para detectar una serie de trastornos genéticos en el embarazo. ¿Cómo se ejecutan estos tests y qué es lo que puede descubrirse? La Dra. Julia Cormano explica la diferencia entre exámenes de detección y pruebas de diagnóstico, qué se puede saber a partir de un examen de sangre, así como también qué esperar de la toma de muestras de vellosidades coriónicas y la amniocentesis.

Scientists, including from UC Davis, have successfully sequenced the coast redwood and giant sequoia genomes, completing the first major milestone of a five-year project to develop the tools necessary to study these forests’ genomic diversity. Over the past 150 years, 95 percent of the ancient coast redwood range and about one-third of the giant sequoia range have been logged. If diversity has declined, it could leave the redwoods vulnerable to drought, fire and other stressors related to climate change. Series: "UCTV Prime" [Show ID: 35170]

Scott Kelly spent a year in the International Space Station while his identical twin Mark Kelly was on earth. UC San Diego and many institutions studied the mental, cardiovascular, immune, genetic, muscular, microbial, bone, and eye changes in both twins to see the effects of long-term space travel. Changes were troubling, so NASA plans several more long-term space flights that will focus on genetic changes, bone loss, loss of vision, brain swelling, and Nutrition. Michael G. Ziegler, MD, is Professor of Medicine Emeritus at UCSD. He has studied astronaut health since 1978. He chaired NASA’s yearly cardiovascular reviews, helped devise current astronaut protocols, and studied physiologic and genomic changes during the Year in Space study.   Series: "Osher UC San Diego Distinguished Lecture Series" [Health and Medicine] [Science] [Show ID: 35085]

A team of engineers at UC Berkeley and the Keck Graduate Institute (KGI) of The Claremont Colleges combined CRISPR with electronic transistors made from graphene to create a new hand-held device that can detect specific genetic mutations in a matter of minutes. The device, dubbed CRISPR-Chip, could be used to rapidly diagnose genetic diseases or to evaluate the accuracy of gene-editing techniques. The team used the device to identify genetic mutations in DNA samples from Duchenne muscular dystrophy patients. Series: "UC Berkeley News" [Show ID: 35130]

Ultrasounds are one of the many tools available to help you have a healthy pregnancy. They can be used to monitor fetal growth, estimate risks for genetic disorders, discover the gender of your baby, and much more. Dr. Julia Cormano discusses the different types of ultrasounds that may be done during your pregnancy and how this technology can provide a unique view of your baby's development.
