Dr. Diane DiEuliis — NDU — Preparing National Security Leaders For The Next Generation Of Threats

Episode Disclaimer — The views presented in this episode are those of the speaker and do not necessarily represent the views of the United States Department of Defense (DoD) or its components.

Dr. Diane DiEuliis, Ph.D. is a Distinguished Research Fellow at National Defense University (NDU — https://www.ndu.edu/), an institution of higher education, funded by the United States Department of Defense, aimed at facilitating high-level education, training, and professional development of national security leaders. Her research areas focus on emerging biological technologies, biodefense, and preparedness for biothreats. Specific topic areas under this broad research portfolio include dual-use life sciences research, synthetic biology, the U.S. bioeconomy, disaster recovery, and behavioral, cognitive, and social science as it relates to important aspects of deterrence. Dr. DiEuliis currently has several research grants in progress, and teaches in foundational professional military education.

Prior to joining NDU, Dr. DiEuliis was Deputy Director for Policy, and served as Deputy Assistant Secretary for Policy and Planning in the Office of the Assistant Secretary for Preparedness and Response (ASPR), Department of Health and Human Services. She coordinated policy and research in support of domestic and international health emergencies, such as Hurricane Sandy, and Ebola outbreaks. She was responsible for implementation of the Pandemic All-Hazards Preparedness Act, the National Health Security Strategy, and supported the Public Health Emergency Medical Countermeasures Enterprise (PHEMCE).

From to 2007 to 2011, Dr. DiEuliis was the Assistant Director for Life Sciences and Behavioral and Social Sciences in the Office of Science and Technology Policy (OSTP) in the Executive Office of the President. During her tenure at the White House, she was responsible for developing policy in areas such as biosecurity and biodefense, synthetic biology, social and behavioral science, scientific collections, and biotechnology. Dr. DiEuliis also worked to help coordinate agency response to public health issues such as the H1N1 flu.

Prior to working at OSTP, Dr. DiEuliis was a program director at the National Institutes of Health (NIH), where she managed a diverse portfolio of neuroscience research in neurodegenerative diseases. She completed a fellowship at the University of Pennsylvania in the Center for Neurodegenerative Disease Research and completed her postdoctoral research in the NIH Intramural research program, where she focused on cellular and molecular neuroscience.

Dr. DiEuliis is a National Merit Scholar, and has a Ph.D. in biology from the University of Delaware in Newark, Delaware. She is the author of over 70 publications.

Scientists Discover Key Food Nutrients Linked to Slower Brain Aging

Understanding the biological processes of getting older could help us lead longer lives, and stay healthier later in life – and a new study links the speed at which our brain ages with the nutrients in our diets.

Researchers from the University of Illinois and the University of Nebraska-Lincoln mapped brain scans against nutritional intake for 100 volunteers aged between 65 and 75, looking for connections between certain diets and slower brain aging.

They identified two distinct types of brain aging – and the slower paced aging was associated with nutrient intake similar to what you would get from the Mediterranean diet, shown in previous studies to be one of the best for our bodies.

A new gene-editing system tackles complex diseases

The human genome consists of around 3 billion base pairs and humans are all 99.6% identical in their genetic makeup. That small 0.4% accounts for any difference between one person and another. Specific combinations of mutations in those base pairs hold important clues about the causes of complex health issues, including heart disease and neurodegenerative diseases like schizophrenia.

Chinese researchers successfully revive human brain frozen for 18 months

In a stunning scientific feat in the field of cryonics, a team from Fudan University in Shanghai achieved a monumental breakthrough by successfully reviving a human brain that had been frozen for as long as 18 months. This record breaking achievement not only shatters previous records in cryogenic technology but has also been published in the esteemed academic journal Cell Reports Methods.

The team led by Shao Zhicheng created a revolutionary cryopreservation method, dubbed MEDY, which preserves the structural integrity and functionality of neural cells, allowing for the preservation of various brain tissues and human brain specimens. This advancement holds immense promise not only for research into neurological disorders but also opens up possibilities for the future of human cryopreservation technology.

Professor Joao Pedro Magalhaes from the University of Birmingham K expressed profound astonishment at the development, hailing the technology’s ability to prevent cell death and help preserve neural functionality as nothing short of miraculous. He speculated that in the future, terminally ill patients could be cryopreserved, awaiting cures that may emerge, while astronauts could be frozen for interstellar travel, awakening in distant galaxies.

Upgrading brain storage: Quantifying how much information our synapses can hold

With each flip you make through a deck of vocabulary word flashcards, their definitions come more quickly, more easily. This process of learning and remembering new information strengthens important connections in your brain. Recalling those new words and definitions more easily with practice is evidence that those neural connections, called synapses, can grow stronger or weaker over time—a feature known as synaptic plasticity.

A Biblical Case for Annihilation — Dr. Bart Ehrman

Annihilationism is the belief that unbelievers will not experience an eternity of suffering in hell, but will instead be “extinguished.” Dr. Bart Ehrman discusses why Jesus and Paul believed in annihilation. Full video: • Exploring Early Christian Narratives…

Dr. Bart Ehrman is the James A. Gray Distinguished Professor of Religious Studies at the University of North Carolina, Chapel Hill, where he has taught thousands of students and won numerous awards.

Bart’s work has been featured in The New York Times, the Washington Post, the Times Literary Supplement, the New Yorker, Time, and Newsweek; he has appeared on National Geographic, CNN, the BBC, NBC’s Dateline, the Discovery Channel, Fresh Air with Terry Gross, the Daily Show with Jon Stewart, the Sam Harris Podcast, and many other top media outlets.

Delgado Podcast features discussions with academics, authors, artists and people who challenge our thinking and help us grow in more compassion. This season is focused on the ways our spirituality, faith, and/or religious identities impact our understanding of justice, race, gender, sexuality, mental health, and religious texts.

Startup claims they have created AI head transplant system, plans to perform first procedure within decade

Scientists put their heads together for an insane medical breakthrough.

Neuroscience and biomedical engineering startup BrainBridge announced that it has created an AI-mechanized system for performing head transplants.

The procedure would graft a head onto the body of a brain-dead donor, maintaining the memories, cognitive abilities and consciousness of the transplanted individual.
