The Sound of Science

Each year brings record-breaking climate events and alarming trends that highlight the urgent need for action on carbon emissions. While industry plays a significant role, our daily activities — driving, heating our homes, even the food we eat — all contribute to the problem. But as daunting as it may seem, scientists are not shying away from finding ways to combat this crisis. In this episode, we explore ORNL's pioneering decarbonization efforts, from carbon capture technology and carbon-free energy to new materials for energy storage. Tune in to discover the innovative research driving us toward a sustainable, net-zero future.

By the early 1990s, Oak Ridge National Laboratory had transformed into a scientific institution with a diverse research portfolio that went well beyond its nuclear roots in the Manhattan Project. But despite this success, the lab was entering a period of uncertainty. Its facilities were showing their age and there were questions about the national labs' role in a post-Cold War world. In this episode, you'll hear how ORNL evolved to become the modern research complex we know today. You'll also hear about how these changes positioned the lab to tackle today's scientific challenges.

In the first part of our 80th anniversary series, you heard how the Manhattan Project helped end World War II with the development and use of the world's first nuclear weapons. The success of this top-secret endeavor ushered in a new era of nuclear science. The expertise used to build the atomic bombs was applied in peacetime to a range of nuclear-inspired research. This research would spawn significant advances in existing fields like chemistry and materials science, and establish completely new ones like neutron scattering and health physics. In this episode, we'll explore the lab's growth and evolution in the decades that followed the war.

As you heard in the last episode, Oak Ridge National Laboratory is celebrating its 80th anniversary. The lab was born out of the Manhattan Project, a top-secret mission that would bring an end to World War II with the production of the world's first nuclear weapons. Clandestine sites across the country worked unique pieces of the puzzle that would become the atomic bomb. While sites in Oak Ridge, Tennessee, and Hanford, Washington, studied and produced the material for the weapons, scientists in Los Alamos, New Mexico, were focused on the design and assembly of the bomb. Those efforts in Los Alamos were led by renowned physicist J. Robert Oppenheimer – a name that should sound particularly familiar this summer. Oppenheimer was the Manhattan Project mastermind behind the atomic bomb, and now his story is the focus of a new blockbuster film based on the Pulitzer Prize-winning biography, “American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer,” by Kai Bird and Martin Sherwin. As part of the 80th celebration, Kai Bird recently visit ORNL and joined us for a discussion on the legacy of Oppenheimer and the Manhattan Project.

Eighty years ago, the U.S. government embarked on a secret mission that would change the world. The Manhattan Project was a massive effort that resulted in the world's first nuclear weapons and the end of World War II. But its legacy extends well beyond the war, as it laid the foundation for groundbreaking science for decades to come. Oak Ridge National Laboratory is one of the facilities born out of the Manhattan Project. Over the past 80 years, its mission has evolved and expanded to become a world leader in supercomputing, materials research, isotopes, clean energy — to name a few — but to this day is still strongly associated with its Manhattan Project roots. In this episode, you'll hear the story of the lab's top-secret origin from Alan Icenhour, the lab's recently retired deputy for operations.

For nearly six decades, the High Flux Isotope Reactor, or HFIR, at Oak Ridge National Laboratory has been one of the world's most powerful research reactors. It has played a critical role in making isotopes for a range of applications, including space exploration, periodic table discoveries and life-saving cancer treatments. However, isotope production isn't HFIR's only claim to fame. The versatile reactor boasts world-class capabilities for neutron scattering, materials testing and analyzing samples at the atomic scale. In this episode, you'll hear from the scientists and engineers who help carry out these missions and ensure the reactor will run for decades to come.

When the universe was formed billions and billions of years ago, the building blocks of life were forged with it. Hydrogen, carbon, iron, nitrogen, calcium, oxygen are just a few of the elements born from the cosmos that make up life on Earth. There are currently 118 known elements and we use the periodic table to organize and understand them. But straightforward as the periodic table seems, it contains a lot of mysteries. Scientists have catalogued more than 3,000 known isotopes and speculate there are thousands more yet to be discovered. The Facility for Rare Isotope Beams, also known as FRIB, has come online at Michigan State University to help researchers in their quest to create new isotopes and study their exotic behavior. FRIB has been years in the making. In fact, several of the instruments and detectors used originated from a historic facility at Oak Ridge National Laboratory. In this episode, you'll hear from several scientists who have been along for the journey about the history and future of this new facility – and what it means for science and society.  

In May 2022, history was made at Oak Ridge National Laboratory. Frontier, the lab's newest supercomputer, officially did what no other computer in the world had done before — it crossed the exascale barrier. If you're not familiar with the field of supercomputing, an exascale computer is an incredibly powerful system that is capable of a quintillion calculations per second. Frontier's arrival marks a new era of computational performance that will help enable scientific breakthroughs never before possible. But this milestone didn't happen overnight. The journey to Frontier has been years in the making, with plenty of challenges and dramatic moments along the way. In this episode, you'll hear a behind-the-scenes account of what it took to launch the world's first exascale computer. 

Electrifying transportation is key to cutting carbon emissions. However, cumbersome cables, lengthy charge times and range anxiety have some potential electric vehicle adoptershesitant to make the switch. Scientists at Oak Ridge National Laboratory are working to make those concerns a thing of the past with a high-power wireless charging technology that could make powering an EV as easy, or easier, than gassing up a car. In this episode you'll hear from the scientists leading this technology, as well as industry partners working with the team to advance the technology and get it to market.  

Soundbite: In our last episode, you heard about how scientists are working to harness the power of the sun on earth with fusion. Achieving fusion on a large scale could bring about a new age of unlimited, carbon-free energy. Scientists are getting closer to making this a reality, but there are still a few hurdles to overcome.  One of those is finding materials that can withstand the insane conditions of a fusion reaction. Oak Ridge National Laboratory already has unique capabilities for testing these materials with the High Flux Isotope Reactor, or HFIR. While a fission reactor like HFIR produces some pretty extreme conditions, it's still no match for what a material will experience inside a fusion reactor. That's where the Material Plasma Exposure eXperiment, or MPEX, project at ORNL comes in. Hear how scientists like Juergen Rapp will use MPEX to take materials testing to the next level. 

Building a sun on Earth to produce unlimited, carbon-free energy may sound like science fiction, but it's not. It's a nuclear process called fusion, where two atoms join together and create an abundance of energy. Recreating the power of a star is no easy feat, but scientists across the globe are hard at work to make it a reality. From materials, to confining sun-hot plasmas, to fuel, there are a lot of scientific challenges to overcome to build a fusion reactor. In this episode, we talked to several Oak Ridge National Laboratory scientists about how they are tackling these problems and why the future of fusion looks brighter than ever right now.

Soundbite: Have you met FRED? The Fine Root Ecology Database — also known as FRED — is a collection of root trait data from research performed around the world. Roots play an important role in all ecosystems, but are often overlooked by computer models. The data in FRED can help computer modelers more accurately predict climate change scenarios. In this shorter installment of "The Sound of Science" podcast series, you'll hear from ORNL scientist and root aficionado Colleen Iversen, who leads the effort to collect data for FRED. 

Deep in the forests of northern Minnesota, lies something that looks a little out-of-this-world. Long boardwalks connect a series of octagonal pods that serve as gateways into the future. But this isn't some secret alien colony. It's a large-scale research project that's studying the effects of climate change on the peatland ecosystem. The project is called the Spruce and Peatland Responses Under Changing Environments experiment, or SPRUCE. The goal of the project is to understand how climate change impact this delicate landscape. In this episode, you'll hear from members of the SPRUCE team about what they've learned from the experiment so far. 

The Arctic tundra of Alaska features a picturesque landscape, teeming with plants and wildlife. But below ground lies a significant threat to the environment. As temperatures rise around the globe, layers of soil known as permafrost, which have been frozen for up to thousands of years, are beginning to thaw. And with that, threatening to release massive amounts of trapped greenhouse gases into the atmosphere. To study these dramatic changes, the U.S. Department of Energy launched the Next-Generation Ecosystem Experiments, or NGEE Arctic, project. NGEE brings together an interdisciplinary team to study the complex scientific processes that occur as the permafrost starts to thaw. In this episode, you'll hear members of the team discuss their research, what it's like to work in the Arctic tundra - including a wildlife story or two. 

Soundbite of "The Sound of Science": In the last episode, we discussed the strange world of quantum mechanics. The laws of quantum mechanics describe the odd behavior of subatomic particles. Harnessing the power of quantum mechanics could create a technological revolution. While quantum technologies might sound like something out of science fiction, the reality is quantum applications in computing, materials, sensors and networking could have a profound impact on our everyday lives. Scientists at ORNL are working to advancing quantum technologies in these areas. In this shorter installment of "The Sound of Science" podcast series, you'll hear from Nick Peters, one of the scientists at ORNL who is working on using quantum to improve network security against cybersecurity threats.

Quantum mechanics. Does the term alone make your brain hurt a little? If so, you're not alone. It's a very complex branch of physics where things are just kind of ... weird. However, it's this strange behavior particles exhibit at the subatomic scale that has the potential to create a technological revolution in computing, materials, networking, and sensing. To harness this power, the U.S. Department of Energy has established a suite of quantum information science research centers at five of its national laboratories. In this episode, you'll hear from several researchers at ORNL to understand what they hope to accomplish.

Since 1943, Oak Ridge National Laboratory has built 13 nuclear reactors — now it's preparing for its 14th, the Transformational Challenge Reactor, or TCR. But this one will be quite a departure from the reactors that have come before. It's going to be 3D printed. TCR aims to revolutionize how a nuclear reactor is built – a process that hasn't really changed much in the past 50 years. In this episode, you'll hear from some of the lab's nuclear and materials experts, an industry partner using technology coming out of TCR, as well as Rita Baranwal, the assistant secretary for the Office of Nuclear Energy in the U.S. Department of Energy.

In just a few short months, COVID-19 has upended daily life around the globe. However, one thing that hasn't changed is the scientific community's drive to find answers and solutions to big problems. And right now, there's no bigger problem than COVID-19. In this episode, you'll hear from ORNL researchers who are applying their expertise in computational science, advanced manufacturing, data science and neutron science to combat the novel coronavirus.

Learn about the remarkable life and legacy of the late Liane B. Russell, one of Oak Ridge National Laboratory's most renowned scientists. She was a pioneer in genetics, a passionate conservationist and an unabashed chocolate lover. In this episode, you'll hear from those who knew her best — and a few whom she inspired.

Geographic information systems are powerful mapping tools that we use on a daily basis without realizing it. Apps for navigation and weather are just a few examples of GIS in our everyday lives. But the applications of GIS span far beyond consumer apps. These complex systems hold massive amounts of data that scientists can use to solve big problems. In this episode, you'll hear how Oak Ridge National Laboratory has used its expertise in GIS to aid in disaster relief; find missing populations for a polio eradication campaign; and map communities using social media.

Plutonium-238 is critical to deep space exploration. The special isotope has powered missions that have enabled us to explore the atmosphere of Saturn, see the heart of Pluto and traverse the surface of Mars. But what if missions like those were no longer possible? That's a question NASA faced not so long ago as the U.S. was in short supply of the isotope. The decision was made to restart pu-238 production and Oak Ridge National Laboratory was the place to do it. In this episode you'll hear from the manager of the plutonium program, as well as from the team that makes the cladding to hold the fuel.

Artificial intelligence is no longer just a subject of science fiction. From personal assistants to self-driving cars, AI is revolutionizing everyday life. While AI may be more prevalent these days, there are still al lot of misconceptions about what it is and what it isn't. In this episode you'll hear from a few of Oak Ridge National Laboratory's AI developers and practitioners. They'll dispel some of those myths and discuss how AI is transforming cancer research, manufacturing and plant biology.
