Defining Regeneration and Non-Regeneration at a Cellular and Molecular Level - Breaking News in Stem Cells

ABO Blood groups represent the first described human molecular polymorphism. The ABO gene encodes variants of a protein (a glycosyltransferase) that produces the short sugar chains on glycoproteins and glycolipids that define the A, B, or O antigens. These antigens are found on red blood cells, plasma glycoproteins, and other cell types in various tissues. Individual humans can have one of four blood types based on the two alleles inherited from both parents at the ABO locus: blood type A, B, AB, or O. UC San Diego professor Pascal Gagneux discusses how recent comparative genome studies have revealed that this polymorphic system is ancient and shared between humans and non-human primates, this despite the fact that none of the great ape species carries all four ABO blood types.

The climate crisis is impacting health, and health care professionals have a pivotal role as advocates for change. The climate crisis must be mitigated by vast reductions in carbon use. Physicians share how they have promoted advocacy, as well as effective ways of messaging, and how leaders serve as trusted sources of information for policymakers and local institutions, and change agents. Panelists: Mark Coleman, MS, author and nature meditation teacher; host, Nature Summit; Robin Cooper, MD, Volunteer Associate Clinical Professor, UCSF Dept. of Psychiatry and Behavioral Sciences; co-founder, Climate Psychiatry Alliance; Edward Maibach, PhD, Mason Distinguished University Professor, George Mason University; Ashley McClure, MD, co-founder, Climate Health Now; Kimberly Williams, PhD, PHR, Executive Director, The National Medical Association; Program Manager, Georgia Clinicians for Climate Action.

From Climate Stress to Activation: The Critical Role of the Health Professional

Humans are unusual in that we depend on shared foods, especially among families and friends and between potential mates. Food sharing occurs between healthy individuals and those that are infirm or elderly. We also differ from other great apes in our early ages at weaning, late ages at maturity, short birth intervals and survivorship decades past menopause. The emergence of these patterns was crucial to early human development. In light of observations among modern East African hunter-gatherers, University of Utah professor James O’Connell evaluates two alternatives. He discusses one hypothesis that focuses on males acquiring big game meat and marrow to provide for mates and offspring. The other hypothesis surrounds how certain kinds of savanna plant food set up the forager interdependence which propelled all aspects of life history change.

In December 2020, Jennifer Doudna received her Nobel Prize in Chemistry during a small, socially-distanced ceremony at her home - followed by takeout. The traditional celebration will have to wait until next year. A videographer and photographer captured the intimate gathering and presentation of the gold medal by Barbro Osher, Sweden’s Honorary Consul General in San Francisco, with Anna Sjöström Douagi representing the Nobel Foundation. Doudna, the Li Ka Shing Chancellor’s Chair in Biomedical and Health Sciences at UC Berkeley, was joined by her husband, Jamie Cate, UC Berkeley professor of molecular and cell biology, son, Andrew, and sister Ellen Doudna of Berkeley.

To Sheng-Ying Pao, the power of reframing CRISPR lies in what is absolutely ordinary: paper. In CRISPaper, Pao revisited a cultural past in the ancient art of papermaking. In ancient China, wild rice was used to make paper. Pao took rice stalks from plants edited with CRISPR and ground the fibers into pulp. She then poured the pulp over a mesh screen. Every time she dipped the screen into water, the plant fibers would lift and resettle on top of the mesh, eventually making paper. Through the genome-edited rice plant, an ancient practice was juxtaposed with cutting-edge technology. Series: "UC Berkeley News" [Science] [Arts and Music] [Show ID: 37388]

An Armband to Control Prosthetic Hands

Dr. Jennifer Elisseeff is the director of the Translational Tissue Engineering Center, a collaboration between the Department of Biomedical Engineering and Wilmer Eye Institute. The lab develops new biomaterials, study stem cells and design new technologies for regenerative medicine. The goal of her lab is to engineer technologies to repair lost tissues. Her lab is examining hydrogels as a scaffold for tissue engineering. Hydrogels are ideal due to their high water content for nutrient and waste transport, and their ability to encapsulate cells and to implant in a minimally invasive manner. The lab is currently focused on developing synthetic-biological hydrogels with highly controlled physical properties and biological function. The discovery of human embryonic stem cells has created the possibility to regenerate any tissue from a single, totipotent cell population.

The Immune System in Regenerative Medicine: Friend or Foe To Stem Cells? - Breaking News in Stem Cells

Just another YouTube video documenting the crazy antics of squirrels hell-bent on reaching peanuts? No, these videos are part of a study to understand the split-second decisions squirrels make routinely as they race through the tree canopy, jumping from branch to branch, using skills honed to elude deadly predators. The payoff to understanding how squirrels learn the limits of their agility could be better robots with better control to nimbly move through varied landscapes, such as the rubble of a collapsed building in search of survivors. It could also lead to a better understanding of movement problems that come with age. How does an animal decide whether or not to take a leap? How do they assess their biomechanical abilities to know whether they can stick the landing? Series: "UC Berkeley News" [Health and Medicine] [Science] [Show ID: 37367]
