Michael Judd is a really cool guy. He lives, and has lived, a very inspiring life. Today his focus is on, as he calls it, “designing for neglect.” That is, creating living food systems that function like natural ecosystems, providing long-term food security with very little input. Many of the species he works with are cultivars of plants we mostly think of as wild species, like America's iconic and only tropical fruit, the Paw Paw. While governments are busy trying to regulate cow farts and developing carbon credits, Michael has been building systems that truly integrate people and the landscape in ways that solve real and pressing problems — combining the indigenous knowledge he gained while living in Latin America with the permaculture design he learned here in the States. From birth to death — we mean that literally, since Michael and Daniel get into natural burial later in this episode — he's developed and implemented systems that dramatically increase his and his family's own sustainability in very real, relatable, and surprisingly simple ways. While we don't believe a utopia has or ever will exist, it's certainly entertaining to imagine what would happen if more people started to implement similar systems in their own lives. We'll be headed south to work with Michael in an upcoming episode of the third season of the WildFed TV show, so stay tuned for that, and in the meantime, prepare to be inspired. Michael is showing, by example, what we can do to increase the amount of nature, food, and personal sovereignty we can have when we start building self-managing, living systems. It can be done, and you can tell from listening to Michael, it can be fun and very fulfilling too.

Scientific discoveries show chronological aging may be written in the epigenome, those chemical tags attached to your DNA that control the way DNA operates.We're finding out more about both types of aging because of scientists like Morgan Levine, Ph.D., a leading voice in the field of aging and longevity science. She focuses her research on the science of biological aging, emphasizing health span over lifespan. “If you take the difference between someone's biological age and chronological age, it should predict the things we care about, the actual things we're trying to prevent—so death, disease,” she says. She's an assistant professor of pathology and the Director of the Laboratory for Aging in Living Systems at Yale University School of Medicine. Her team looks at using bioinformatics to quantify the aging process and test how lifestyle and pharmaceuticals alter the rate of aging. She's also a founding Principal Investigator at Altos Labs, a biotech company that focuses on cellular rejuvenation programming to restore cell health and resilience.Today, she's going to talk about the science of aging and longevity explored in her new book, “True Age: “Cutting-Edge Research to Help Turn Back the Clock.” Three main drivers—health behaviors, recent stressors and adversity, and genetics—determine your biological aging. She shares how to measure your own biological age and why you should track your aging regularly. This conversation gets into topics and makes them make sense for your own aging, like:Epigenetics & epigenetic clocksDNA methylation & telomeresCell lifespan Ageotypes (molecular assessment of aging)Phenotypic ageThe “Ceiling” effectThe “CALERIE” trialNutrition & aging (plants, fasting, ketosis)Fitness & aging (energy & brain health)Rest & relaxation (sleep & biological programming)Morgan gives great takeaways on how you can make lifestyle changes to maintain your youthfulness—both inside and out—with low-risk, data-driven biohacking.

Unless otherwise noted, all Web addresses mentioned were functional as of 5-6-22. TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the weeks of May 9 and May 16, 2022.   This episode from is part of a series this year of episodes related to trees and shrubs. MUSIC – ~14 sec – instrumental. That's part of “New Spring Waltz,” by the late Madeline MacNeil, who was a well-known and highly regarded musician based in Virginia's Shenandoah Valley. Each new spring brings a chance to focus on the life cycles of wildlife.  This mid-spring episode of Water Radio explores some connections among nesting birds, trees, and water.  Have a listen for about 30 seconds to three mystery sounds, and see if you know these three bird species who nest in trees near water, either always or at least sometimes.  And here's a hint: you'll be singing a melodious trill, if you hit this mystery out of the park. SOUNDS  - 29 sec. If you guessed two warblers and an oriole, you're right!  And you get bodacious bird bragging rights if you recognized, first, the Prothonotary Warbler; second, the Northern Parula, also a kind of warbler; and third, the bird for which Baltimore's baseball team is named, the Baltimore Oriole.  All three of these songbirds are found in Virginia in the spring and summer breeding season.  During that period, the Prothonotary Warbler is common in Virginia's central and southern Coastal Plain and can occasionally be found in some other parts of the Commonwealth; the Baltimore Oriole is common outside of the Coastal Plain; and the Northern Parula is common statewide.  The three species show a range of attachment to water-side trees as their nesting habitat.  The Prothonotary Warbler is particularly known for nesting in cavities in trees around water; in fact, the bird is sometimes called the “Swamp Warbler” in the southeastern United States.  The Northern Parula typically nests in trees along rivers and wetlands, especially in areas where it can find the materials it prefers for making its hanging nests: Spanish Moss or a kind of stringy lichen; this bird is also known to make nests out of debris left in trees after floods.  The Baltimore Oriole is the least water-attached of these three species, being found nesting high in trees in many areas outside of deep woods, including parks and yards; however, streamsides are among the species preferred areas for the bird's fibrous, hanging nests. If you're near streams, rivers, or wetlands and you see or hear any of these three birds, look to nearby trees for cavities or hanging materials that may be harboring the birds' next generation. Thanks to Lang Elliott for permission to use the bird sounds, from the Stokes Field Guide to Bird Songs.  Thanks also to Janita Baker of Blue Lion Dulcimers and Guitars for permission to use Madeline MacNeil's music, and we close with about 25 more seconds of “New Spring Waltz.” MUSIC – ~26 sec – instrumental.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the weeks of April 25 and May 2, 2022.  This episode is part of a series this year of episodes related to trees and shrubs. MUSIC – ~12 sec – instrumental. This week, that excerpt of “Baldcypress Swamp,” by Timothy Seaman of Williamsburg, Va., sets the stage for exploring some of Virginia's tree species found in or near water, along with some of the water places those trees inhabit.  We start with a series of guest voices calling out 16 native Virginia tree species that can be found around watery habitats.  Have a listen for about 25 seconds. VOICES and INSTRUMENTAL MUSIC - ~27 sec - “American Sycamore.  Atlantic White-cedar.  Baldcypress.  Black Gum.  Black Willow.  Boxelder.  Eastern Hemlock.  Hackberry.  Overcup Oak.  Red Maple.  Red Spruce.  River Birch.  Silver Maple.  Swamp Tupelo.  Water Hickory.  Water Tupelo.” Those 16 and other tree species can be found in a wide variety of water-related habitats in Virginia.  The Virginia Department of Conservation's 2021 report, “The Natural Communities of Virginia: Ecological Groups and Community Types,” lists over 30 community types associated with aquatic habitats.  Tree species are a characteristic of the vegetation in over 15 of those community types, ranging from Piedmont/Mountain Small-stream Alluvial Forests, to Coastal Plain/Piedmont Bottomland Forests, to Coastal Plain Depression Swamps and Ponds, to Maritime Swamps.  More generally speaking, you can find native Virginia trees beside small streams in uplands, for example, Eastern Hemlock; beside large rivers in the mountains or Piedmont, for example, American Sycamore and Silver Maple; beside large Coastal Plain rivers, for example, Overcup Oak and Water Hickory; and in a variety of swamps and other wetlands, for example, Baldcypress, Atlantic White-cedar, and Swamp Tupelo. Here's to Virginia's many tree species, its many water habitats, and the many combinations of those two groups of natural resources.  Thanks to seven Virginia Tech colleagues for lending their voices to this episode.  Thanks also to Timothy Seaman for permission to use this week's music, and we close with about 15 more seconds of “Baldcypress Swamp.” MUSIC – ~15 sec – instrumental.

TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of April 18, 2022.  This update of an episode from July 2017 is part of a series this year of episodes related to trees and shrubs. MUSIC – ~14 sec That's part of “The Ash Grove,” a traditional Welsh tune performed by Madeline MacNeil, on her 2002 album, “Songs of Earth & Sea.”  Born in Norfolk and raised in Richmond, Ms. MacNeil was a well-known and highly regarded musician based in Virginia's Shenandoah Valley until her passing in 2020. The music opens an episode where we revisit the status of North American ash trees and explore the water impacts of pest damage to trees generally. As noted in the July 2017 episode on ashes, North America is home to 16 native ash species, with six of those occurring naturally in Virginia.  The two most common ash species in Virginia are White Ash, which tends toward upland habitats, and Green Ash, which is often found along streams and rivers.  In those areas, Green Ash can be a significant portion of the vegetation and help create habitats, improve water quality, and stabilize flows.  Both species provide food for a variety of animals and both have been widely planted in cities and towns. Since the early 2000s, ash tree populations have been devastated by the spread of the Emerald Ash Borer, a beetle native to Asia.  As of April 2022, the insect had been found in at least 35 states and the District of Columbia, and in nearly all of Virginia.  In an affected tree, the insect's larvae create a network of tunnels that impair the tree's transport of water and nutrients, eventually killing the tree.  Once an area's invaded, ashes are unlikely to survive for more than a few years without expensive chemical treatment of individual trees.  At the scale of whole forests, researchers and managers are exploring the use of parasitoid wasps as a biological control method. The Emerald Ash Borer is only one of many pest species threatening different trees in Virginia and elsewhere.  Several of these pests have been the subject of research on their water-related, or hydrologic, impacts.  Researchers are interested in how loss of tree leaves or death of trees can affect evaporation, soil moisture, water-table levels, streamflows, water chemistry, and snowpack.  Those water-cycle processes are in turn connected to ecosystem pathways of carbon, nutrients, and energy, all being affected by climate changes.  From all of these connections, little ash-boring beetles become part of a biosphere-sized story. Thanks to Janita Baker of Blue Lion Dulcimers and Guitars for permission to use Madeline MacNeil's music,” and we close with about 25 more seconds of “The Ash Grove.” MUSIC – ~24 sec – instrumental.

From Background Tab: “After only 1-5 years of infestation, the larvae create extensive tunnels under the bark that disrupt the tree's ability to transport water and nutrients, which eventually girdles and kills the tree. The length of this process depends on tree age, health, and EAB density in the area but no ash tree is safe - 99% of infested ash will die.” From Distribution Tab: “In the U.S., EAB targets 16 species of native ash trees (Fraxinus spp.) and white fringetree (Chionanthus virginicus).  In Virginia, white ash (Fraxinus americana) and green ash (Fraxinus pennsylvanica) are the most commonly found, though there are four other species that have limited ranges (pumpkin, black, blue, and Carolina ash). In the wild, ash often prefers wetter environments and are dominant species along rivers and streambanks.  Ash decline and death may have a negative impact on streambank stabilization and waterways in these rural areas.  Though only a small percentage of Virginia's forests are composed of ash (2-3%), urban areas can have tree inventories tallying up to 13% ash.  This is where dead ash poses the most risk!” From Biological Control Tab: “Biological control (or “biocontrol”) is a management strategy that involves releasing natural enemies from the pest's native range to control the pest at a given location.  Researchers identified wasps in the early 2000s from Eastern Asia that had co-evolved with emerald ash borers as a parasite to control its populations.  They then conducted extensive research in quarantined U.S. labs to study their life cycle, environmental parameters, and host species.  After nearly a decade of trials, only four wasp species passed the strict requirements set by the USDA-APHIS (Animal and Plant Health Inspection Service) and were approved for release.  APHIS now rears these wasps in large quantities then collaborates with federal, state, and local governments, as well as land owners to release them at approved sites.  These tiny stingless wasps lay eggs in EAB eggs or larvae, effectively killing the EAB host, and are commonly called “parasitoids.” ...These wasps do not harm humans in any way, they only target emerald ash borer as a host. The use of these biocontrol agents in suppressing EAB has shown promising results, but it will take years of controlled releases and research before we see successful parasitism and a reduction of the EAB population.” SOURCES Used for Audio Samuel H.
