Mining metals and minerals from seawater Jul 25, 2023

The modern world runs on electronic devices and energy systems that are powered by valuable elements such as lithium and uranium. There are a limited number of terrestrial mines that produce energy-critical elements, which makes the supply of these materials prone to disruption. So researchers are looking to an unconventional source: seawater. Almost every element on the periodic table can be found in global oceans–but most are dissolved in ultralow concentrations. In this episode of Stereo Chemistry, we’ll hear from scientists in the United States and European Union about why they’re interested in extracting metals and minerals from seawater and how they’re using chemistry to do it.

Microplastics pollute our drinking water: What are the risks? Feb 21, 2023

Researchers reported finding microplastics in drinking water nearly 5 years ago, prompting California lawmakers to require monitoring of the state’s drinking water for the tiny particles. But in 2018, there were no standard methods for analyzing microplastics. So California regulators reached out to chemists and toxicologists from all sectors to develop those methods. They also sought assistance in developing a health-based limit to help consumers understand what the monitoring results mean for their health. In this episode of Stereo Chemistry, we will hear from some of the scientists leading those groundbreaking efforts.

Lithium mining’s water use sparks bitter conflicts and novel chemistry Sep 13, 2022

Replacing gas cars with electric ones is a main pillar of plans to fight climate change. But the lithium-ion batteries used in electric cars come with a cost. Communities near the Salar de Atacama in Chile, where about a quarter of the world’s lithium is extracted from salty aquifers, say mining companies pose a serious threat to the local environment and their access to water. Mining companies strongly dispute those claims. In this episode of Stereo Chemistry, we’ll explore the environmental factors at play in the salar and the differing perspectives on how best to measure impact. And we’ll hear from a new group of mining start-ups that claim they can use chemical methods—as yet unproven—to extract lithium without the same impact on water.

This is the first episode in a new series exploring the future of water.

Bonus: The sticky science of why we eat so much sugar May 31, 2022

Our bodies need sugar to survive. But most of us consume way more than we actually need, and many foods and beverages pack a dose of added sweeteners. So why are we eating all of this extra sugar? This month, Stereo Chemistry is sharing an episode of the podcast Tiny Matters that examines that question. In the episode, hosts Sam Jones and Deboki Chakravarti explore sugar’s impact on our bodies and trace how a genetic mutation that helped our distant ancestors survive is influencing our health today. And they dig into the debate around whether sugar can fairly be called addictive.

Note: This episode contains discussion of addiction and eating disorders.

Bonus: There’s more to James Harris’s story Apr 27, 2022

Chemists may know James Harris as the first Black scientist to be credited with codiscovering an element. In fact, we referenced this in a previous episode of Stereo Chemistry about making superheavy elements. But beyond this memorable factoid, details about the accomplished nuclear chemist are scarce, and most sources repeat the same superficial information. Kristen Frederick-Frost, curator of modern science at the Smithsonian’s National Museum of American History, wants to change that. After discovering that the museum's database lacked material on Harris, she scoured archival records and sought out former colleagues, friends, and family members to fill in details of his life and career. In this bonus episode of Stereo Chemistry, host Kerri Jansen and special guest Dr. Darryl Boyd join Frederick-Frost to explore James Harris’s story beyond the discoveries that made him famous. And we even get an unexpected peek into his lab, courtesy of the US National Archives. Boyd, a polymer chemist, previously researched James Harris while writing a short article for C&EN’s “Black Chemists You Should Know About.” A transcript of this episode is available at bit.ly/37P0qpY.

Bonus: The helium shortage that wasn’t supposed to be Mar 24, 2022

Helium shortages can derail research and threaten expensive instruments that depend on the gas to operate safely. In late 2020, analysts predicted—and we reported—that pressures on the global helium market were likely to ease as new production capacity came online. Today, helium users are again facing price spikes and limited supplies, driven by a variety of factors including political instability in Europe and technical malfunctions at key suppliers. In this bonus episode of Stereo Chemistry, C&EN industrial gas reporter Craig Bettenhausen explains how we ended up here again and how the outlook for the global helium market has evolved. A transcript of this episode is available at bit.ly/3tBSGzF.

Ep. 35: Grad students, lab injuries, and workers’ compensation—it’s complicated Nov 17, 2020

Many grad students may be surprised to learn their university’s policies for reimbursing medical fees for lab injuries do not cover grad students, or cover grad students only under certain circumstances. And it can be hard to get clarity on what is and is not covered. That’s left some grad students in an uncomfortable limbo of seeking answers after they’ve already racked up thousands of dollars in bills for an injury in the lab. In the latest episode of Stereo Chemistry, we uncover the source of this confusion and ask what—if anything—grad students can do about it.

Ep. 32: Should organic chemistry’s name reactions go the way of mouth pipetting? Aug 19, 2020

Scientists have been naming ideas, theorems, discoveries, and so on after other scientists for a very long time (Newton’s laws of motion, anyone?). Chemists are no different. They’ve been naming reactions after each other since about the early to mid 1800s. Nowadays, organic chemists in particular use them as a kind of shorthand. However, because the majority of name reactions honor white men, some organic chemists wonder if using these names is exclusionary. In the latest episode of Stereo Chemistry, host Kerri Jansen and reporter Leigh Krietsch Boerner hear from a plethora of organic chemists on how reactions get named, who they’re named after, and whether the practice should stop.

Bonus episode: Talking TSCA—is the chemical law living up to expectations? Jun 17, 2020

This month marks 4 years since the Toxic Substances Control Act, or TSCA, was revised to boost confidence in chemical safety in the US by strengthening regulations. The updated law gave the Environmental Protection Agency sweeping new authority to ensure that the tens of thousands of chemicals in everyday products do not pose unreasonable risks to human health and the environment. In this bonus episode of Stereo Chemistry, host Kerri Jansen and C&EN senior reporter Britt Erickson examine how the EPA is using that authority to evaluate new chemicals before they hit the market and to assess the risks of chemicals that have been in use for decades. Is the EPA protecting public health by sufficiently evaluating the risks of chemicals, or is it giving industry a free pass to market chemicals with little toxicity data?

Ep. 30: The chemical culprit in 2019's mysterious vaping illnesses—what we still don't know May 27, 2020

Months before the novel coronavirus took hold of the globe in late 2019, clusters of patients began appearing in emergency rooms throughout the US with a mysterious lung disease. Investigators quickly linked the illnesses not to a pathogen, but to patients’ use of vaping products. By examining the chemicals in these products, they eventually found a chief suspect: vitamin E acetate. The compound was being used as a cutting agent in some counterfeit or illicit cannabis-based vaping products. Still, many questions remain about how vitamin E acetate could have caused those injuries and whether it was acting alone. In this episode of Stereo Chemistry, host Kerri Jansen and C&EN senior reporter Britt Erickson sift through the complicated chemistry of vaping and explore some new evidence in the investigation. They’ll also discuss how the tragic events of last summer could prove to be a wake-up call for chemical regulators as they evaluate vaping products.

Ep. 29: This virus is here now, it's going to stay with us May 01, 2020

As COVID-19 continues to spread, so does the effort to treat and vaccinate against the novel coronavirus that causes the disease. Around the world, scientists are working nonstop on the different therapies that they hope will quell the loss of life during this pandemic while, at the same time, setting us up to prevent future outbreaks. What’s not clear is which, if any, of these treatments will work. Much about SARS-CoV-2 remains unknown. In this episode of Stereo Chemistry, we dig into the efforts to beat the novel coronavirus and why, in some cases, it’s like throwing spaghetti up against the wall to see what sticks.

Bonus episode: That just isn’t how you land on the moon without crashing Apr 10, 2020

Fifty years ago this week, an explosion on the Apollo 13 moon mission stranded three astronauts hundreds of thousands of miles from home. You probably know that Fred Haise, Jim Lovell, and Jack Swigert made it home safely (water landing shown, with two of the astronauts in white). You may not know the chemist behind the rocket engine that saved them, which began its life as an apparatus for measuring chemical reaction rates. This bonus episode of Stereo Chemistry tells the story of the engine’s design with help from two of the people who created it. Listen now to a tale that starts with an explosion and ends with SpaceX’s pioneering reusable rockets, with one small step for a man along the way. CORRECTIONS: This episode was updated on April 15, 2020, to reflect that Fred Haise, not Ken Mattingly, flew aboard Apollo 13. On April 22, 2020, this podcast description was also corrected to reflect Haise's role and clarify that the photo shows only two of the astronauts.

Ep. 28: So that's why we threw a robot into the back of a truck Mar 18, 2020

Chemistry is going the way of computing: It’s getting smaller and faster. High-throughput experimentation, or HTE, is part of this push. Borrowing from biologists and biochemists, HTE has brought in microplates and multichannel pipettes to miniaturize reactions, as well as robots to run those reactions rapidly without sacrificing precision. But it’s also been around for decades. So why are so many in the field excited about HTE right now? Stereo Chemistry looks at the technology and culture shift behind the current buzz.

Ep. 26: Evolution is kind of the be all end all in the problem of influenza Jan 31, 2020

Although the Wuhan coronavirus is currently dominating headlines across the globe, influenza kills hundreds of thousands of people worldwide each year. In the US, millions of people roll up their sleeves annually for a flu shot. But this ritual is confusing for many. Why is it that most vaccines are effective for a lifetime while the flu vaccine is only effective for a year? And why do we sometimes get the flu even when we’ve gotten the vaccine? The answer is evolution: the flu is constantly evolving to evade our immune systems. In this episode of Stereo Chemistry, scientists who study flu evolution and pandemics explain what makes fighting the flu so difficult. For more, visit cenm.ag/flucast.

Ep. 25: It was like, bam, half the ozone layer over Antarctica is gone Dec 20, 2019

The discovery of the ozone hole in the mid-1980s sent shock waves through the scientific community and society at large. As scientists scrambled to make sense of the unprecedented phenomenon, a clear culprit emerged. Chlorofluorocarbons (CFCs)—once thought of as near-miraculous compounds that revolutionized refrigeration—were suddenly revealed to be one of the biggest environmental dangers known to humankind. What followed was an international push by scientists, media, and policy makers to ban CFCs. In October 2019, NASA announced the ozone hole is the smallest recorded since 1982. In this episode of Stereo Chemistry, we hear from some of the scientists who were instrumental in discovering—and helping heal—the ozone hole and who think lessons learned could help us fight climate change.

Rocket propellant research had its heyday in the mid-20th century, when the space race and the Cold War meant chemists had plenty of money and long leashes. Few of their most interesting ideas ended up in working rockets, but they charted new areas of chemical space, some of which, like boron chemistry, have proved useful in other fields. Geopolitical shifts, along with a growing emphasis on health, safety, and the environment, dampened propellant chemistry in the last decades of the 1900s. But the need for high-performance propellants hasn’t gone away, and neither has chemists’ interest in pushing the envelope. In this episode of Stereo Chemistry, we hear from chemists who lived through the heady days of the ’50s and ’60s and the ones carrying rocket chemistry’s torch today.

Ep. 22: I didn’t know they were going to be worth billions—A conversation with John Goodenough Aug 29, 2019

Without fail, the name John Goodenough crops up during Nobel Prize season. Many scientists believe he’s deserving of chemistry’s top honor. The University of Texas at Austin materials scientist is credited with developing a material that led to mass commercialization of lithium-ion batteries, the technology that powers our smartphones, laptops, electric vehicles, and other gadgets big and small. Though Goodenough, aged 97, hasn’t yet won a Nobel Prize, he’s not mired down by what could have been. He is renowned for his scientific accomplishments, warm personality, and infectious laugh. In this episode of Stereo Chemistry, C&EN reporter Mitch Jacoby joins cohost Kerri Jansen to tell the story of how a former meteorologist with a background in physics came up with a key material that enabled an electronics revolution and how he continues to pursue big questions in electrochemistry today.

Register for C&EN’s Nobel Prize predictions webinar at bit.ly/nobelwebinar19.

UPDATE: We're happy to announce that Goodenough, along with fellow battery pioneers M. Stanley Whittingham and Akira Yoshino, has won the 2019 Nobel Prize in Chemistry. Read our coverage of the award and these scientists' contributions to lithium-ion batteries at C&EN.

CORRECTION 10/23/19: The material Akira Yoshino used for his seminal battery anode was petroleum coke, a graphite-like material derived from petroleum. Researchers, including Samar Basu, had previously worked with graphite but found that it broke down in the battery’s electrolyte. Also, estimates for the voltage of Stan Whittingham’s TiS2 battery vary. This podcast episode refers to a 2.4-volt battery; some sources estimate the voltage at 2.5 V.

Ep. 21: Culture always starts at the top, but it also starts from the bottom Aug 09, 2019

In our last episode of Stereo Chemistry, we talked to chemists who had survived accidents at the bench to learn what went wrong and what lessons we could share to improve lab safety. In this episode, we’re looking at what it takes to build a culture of safety. That is, what can organizations do to let researchers know that their safety is not only valued, but expected? Hosts Jyllian Kemsley and Matt Davenport talk to experts about the importance of leadership, commitment, and education to transform lab safety from an exercise in compliance to a core element of the central science.

Ep. 20: What happens when you take risks? Jul 24, 2019

Research science is full of hazards. Chemists and safety professionals do their best to minimize the danger, but accidents do happen and the stakes can be extremely high. So how can chemists ensure that when things do go wrong—or when they nearly go wrong—that we learn from those experiences to work toward a safer future? Communication is key. In this episode of Stereo Chemistry, we talk with four chemists who have survived accidents and shared their stories so others can learn from them.

Ep. 19: This is a mess. But there might also be gasoline in here. Jun 22, 2019

In the aftermath of a building fire, investigators study the scene for clues to the fire’s cause. They look for burn patterns and suspicious materials while chemists search charred debris for traces of flammable liquids. But investigating fires is not as straightforward as it once was, because investigators now know more about the complexity of how fires burn. In this episode of Stereo Chemistry, host Kerri Jansen explores how scientists are working to better pinpoint specific chemicals amid the chaos a fire leaves behind and how a new understanding of the chemistry and physics of fire has revolutionized the way fire scenes are interpreted.

Ep. 18: Our job is to make sure we have the data May 22, 2019

Robots in the ocean are giving scientists more details about processes above and below the surface that affect our weather, our food supply, and more. They’re also helping chemical oceanographers understand and record the effects that climate change is having on our waters. The past 2 decades have seen a growing fleet of uncrewed research vessels and a proliferation of chemical sensors, which together are giving chemical oceanographers access to an unprecedented wealth of data. That’s changing not just the way they think the oceans work but also how they themselves work. In this episode, pioneers of ocean robotics and scientists developing new sensors for the crewless vehicles tell tales of that work. And hacky sacks.

Ep. 17: If you want to change the element, you have to change the nucleus Apr 21, 2019

In honor of the International Year of the Periodic Table, Stereo Chemistry explores the stories behind some of the elements in this episode. C&EN and ACS on Campus hosted periodic table pub trivia during the ACS Spring 2019 National Meeting in Orlando, Florida. Inspired by the event, its participants, and its questions, host Kerri Jansen investigated what it takes to make a new superheavy element, starting a half century ago and tracking the making of new elements through time. She tells the tales of scientists commonly associated with shaping the periodic table but also of the unsung heroes behind the scenes.

Ep. 16: It’s all of these things that none of us get trained for Mar 17, 2019

Being a chemistry professor is Jen Heemstra’s dream job. How she got there was a bit of a nightmare. But now she’s running her own team at Emory University and has become a social media celebrity by sharing her experiences and leadership advice on Twitter. She credits her personal tragedy and professional setbacks for making her who she is today. In the latest episode of C&EN’s Stereo Chemistry podcast, we spent two days with Heemstra and her team to learn more about her and her approach to graduate education. Heemstra’s adversity has not only shaped her attitude but also how she runs her lab. She’s helping her students develop skills that go beyond the bench—things like how to manage motivation, how to develop research ideas, and how to write grants. Listen now to hear more about Heemstra’s journey and philosophy.

Ep. 15: Being scientists together in a relationship is the very best thing in the world Feb 10, 2019

They say love is a many-splendored thing, and we have to agree. In the latest episode of Stereo Chemistry, love unites rotovap romance, intimate feelings formatted for the Journal of the American Chemical Society, and the slow but tireless march of equality. C&EN spoke with five chemistry couples about their love stories, as well as what advice they have for those trying to give love a chance in a science, technology, engineering, and mathematics (STEM) profession. You’ll hear real talk about fears and doubts, about struggling with work-life balance, and about solving the two-body problem. And you’ll also hear some of the cutest gosh-darn stories we’ve ever had the privilege of sharing.

Ep. 14: On the face of it, RNA is a terrible drug target Jan 03, 2019

RNA should be a terrible drug target. It’s long, noodle-like structure lacks the nooks and crannies that small molecule drugs use to grab onto proteins and thereby control them. But a decades-old disregard for RNA is starting to change. In August 2018, the US Food and Drug Administration approved the first-ever RNA interference (RNAi) drug, which uses a double-stranded RNA molecule to prevent the production of disease-related proteins. In the past two years, several startups have launched to show that some RNAs can, just like proteins, be drugged with small molecules. And a third group of companies recently emerged with plans to drug proteins that make modifications to RNA, part of the budding field of epitranscriptomics. In this episode, C&EN visits Alnylam Pharmaceuticals, Novartis, and Accent Therapeutics to discuss these three strategies, and to understand how RNA-modulating therapies will compete in the wider world of drug discovery.

Ep. 12: Do you want to be the guy who rips out a page from a 1550s’ New Testament? Nov 21, 2018

The smell of old books. The crinkle of the yellowing pages. While admiring the wonders of libraries, have you ever wondered how paper ages and why some sheets last longer than others? Paper conservation scientists have. Stereo Chemistry caught up with a slew of these researchers after hearing about a special collection of books at the U.S. Library of Congress. The more than 1,000 volumes in this collection have essentially donated their bodies to science. We embarked on a time-travel journey to learn more about this collection and the self-trained chemist, a polarizing figure, who donated it and who helped bring about modern-day paper preservation testing.

Ep. 7: The good ones don’t dare to touch Jul 26, 2018

The European X-ray Free Electron Laser recently came online as the biggest and brightest source of X-rays on planet Earth. This will allow chemists to do groundbreaking research, but with great science comes great responsibility. In our latest Stereo Chemistry podcast, C&EN contributing editor Mark Peplow visits the X-ray facility to learn about its growing pains, its staff’s unique approach to keeping it running, and some of its early successes. “Kitty In The Window” by Podington Bear is licensed under a Attribution-NonCommercial 3.0 International License. http://freemusicarchive.org/music/Podington_Bear/Said_Lion_To_Lamb_Box_Set_Disc_3/Kitty_In_The_Window “The Confrontation” by Podington Bear is licensed under CC BY-NC 3.0. http://freemusicarchive.org/music/Podington_Bear/Passages/The_Confrontation “Gerald's Place” by Raleigh Moncrief is licensed under CC BY-NC 3.0. http://freemusicarchive.org/music/Raleigh_Moncrief/Vitamins_EP/Raleigh_Moncrief_-_Vitamins_EP_-_06_Geralds_Place Matt stands by his awful William Lawrence Bragg pun, but does feel conflicted over not including William Henry Bragg, Max von Laue, photographic plates, and other important players in the history of X-ray crystallography.

Ep. 6: Everything will be druggable Jun 17, 2018

Although genome sequencing has helped scientists reveal proteins wreaking havoc in our bodies, that doesn’t guarantee scientists can invent the drugs to take them down. Depending on who you talk to, up to 85% of the human proteome is currently “undruggable,” meaning these proteins lack easy-to-find pockets where therapeutics, such as small molecules, can bind. But a wave of biotech companies, each one armed with new technology, has arrived to tackle the problem. Industry and academic scientists explain why they think the business and scientific environment is ripe for finally overcoming the most elusive drug targets.

Ep. 3: The authors declined to discuss the work with C&EN for this story Mar 06, 2018

C&EN reporter Tien Nguyen takes us inside her months-long dealings with ChemRxiv, one of chemistry’s new preprints servers. She examines the benefits, questions, and frustrations presented by the server—not the least of which was chemists unwilling to discuss their own work with us. But it’s not all doom and gloom. We kinda got a Science publication out of this story. UPDATE: On March 16, 2018, Angewandte Chemie announced on Twitter that its editorial board voted to allow submissions of papers posted as preprints on ChemRxiv. https://twitter.com/angew_chem/status/974603394219462656?s=20 Nominate chemists for C&EN’s Talented 12 Class of 2018: http://talented12.cenmag.org/nominate-candidates-for-2018/ All music in this podcast is by Lee Rosevere and licensed under CC BY 4.0. https://creativecommons.org/licenses/by/4.0/ The music you heard first and most often was “Puzzle Pieces.” http://freemusicarchive.org/music/Lee_Rosevere/Music_For_Podcasts_2/Lee_Rosevere_-_Music_for_Podcasts_2_-_10_Puzzle_Pieces The music just before the break was “Sad Marimba Planet,” and the music playing during the call for T12 nominations was “Southside.” http://freemusicarchive.org/music/Lee_Rosevere/Music_for_Podcasts_4/Lee_Rosevere_-_Music_for_Podcasts_4_-_02_Sad_Marimba_Planet http://freemusicarchive.org/music/Lee_Rosevere/Music_for_Podcasts_4/Lee_Rosevere_-_Music_for_Podcasts_4_-_09_Southside And the music at the end of the episode is “Credit Roll.” http://freemusicarchive.org/music/Lee_Rosevere/Music_For_Podcasts/Lee_Rosevere_-_Music_For_Podcasts_-_13_Credit_Roll Hosted by Tien Nguyen, Matt Davenport, and Kerri Jansen Written by Tien Nguyen Produced by Matt Davenport
