In the Existential Hope-podcast (https://www.existentialhope.com), we invite scientists to speak about long-termism. Each month, we drop a podcast episode where we interview a visionary scientist to discuss the science and technology that can accelerate humanity towards desirable outcomes.

Xhope Special with Foresight Fellow Morgan Levine.

Morgan Levine is a ladder-rank Assistant Professor in the Department of Pathology at the Yale School of Medicine and a member of both the Yale Combined Program in Computational Biology and Bioinformatics, and the Yale Center for Research on Aging. Her work relies on an interdisciplinary approach, integrating theories and methods from statistical genetics, computational biology, and mathematical demography to develop biomarkers of aging for humans and animal models using high-dimensional omics data. As PI or co-Investigator on multiple NIH-, Foundation-, and University-funded projects, she has extensive experience using systems-level and machine learning approaches to track epigenetic, transcriptomic, and proteomic changes with aging and incorporate.
this information to develop measures of risk stratification for major chronic diseases, such as cancer and Alzheimer’s disease. Her work also involves development of systems-level outcome measures of aging, aimed at facilitating evaluation for geroprotective interventions.

What does the future of aging and longevity hold? Can science hack the human lifespan? Even if we can, SHOULD we…?

People aren’t dying as early or as easily as they used to. Innovations in modern medicine, health, and hygiene helped us extend our lives by decades, but what comes next? Would you rather live to be a healthy and hearty 90 or live to be 150 but wither away for the last 60 years? We’ll talk about it in this episode of Far Out.

An actual ethicist thinks that we might get a Terminator future soon if we keep making AI too advanced.

Despite its checkered reputation, cryptocurrency is being considered by a handful of academics as a means to funnel funds into translational research. Is the trend likely to spread? Laura DeFrancesco and Ariel Klevecz investigate.

A study 29 years in the making shows how bison reintroductions can create richer ecosystems and resilience against climate change in North America.

A team of researchers at the Sorbonne University of Paris reports a new way to emulate black hole and stellar accretion disks. In their paper published in the journal Physical Review Letters, the group describes using magnetic and electric fields to create a rotating disk made of liquid metal to emulate the behavior of material surrounding black holes and stars, which leads to the development of accretion disks.

Prior research has shown that massive objects have a gravitational reach that pulls in gas, dust and other material. And since such massive objects tend to spin, the material they pull in tends to swirl around the object as it moves closer. When that happens, gravity exerted by materials in the swirling mass tends to coalesce, resulting in an accretion disk. Astrophysicists have been studying the dynamics of accretion disks for many years but have not been able to figure out how angular momentum is transferred from the inner parts of a given accretion disk to its outer parts as material in the disk moves ever closer to the central object.

Methods used to study accretion disks have involved the development of math formulas, computer simulations and real-world models using liquids that swirl like eddies. None of the approaches has proven suitable, however, which has led researchers to look for new models. In this new effort, the researchers developed a method to generate an accretion disk made of liquid metal bits spinning in the air.

Although plant-based polylactic acid (PLA) bioplastic is acclaimed for its biodegradability, it can take quite a long time to degrade if the conditions aren’t quite right. Bearing this fact in mind, Washington State University scientists have devised a way of upcycling it into a 3D-printing resin.

“[PLA] is biodegradable and compostable, but once you look into it, it turns out that it can take up to 100 years for it to decompose in a landfill,” said postdoctoral researcher Yu-Chung Chang, co-corresponding author of the study. “In reality, it still creates a lot of pollution. We want to make sure that when we do start producing PLA on the million-tons scale, we will know how to deal with it.”

To that end, Chang and colleagues developed a process in which an inexpensive chemical known as aminoethanol is used to break down the long chains of molecules that make up PLA. Those chains are rendered into simple monomers, which are the basic building blocks of plastic. The process takes about two days, and can be carried out at mild temperatures.
