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...

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...

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...

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...

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.

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...

Late last year, C&EN contributing editor Mark Peplow toured a new battery company's R&D facility in Sweden.

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 scie...

For its latest episode, Stereo Chemistry handed its recorders over to kid journalists interviewing grown-up chemists about cutting-edge research. Listen in as the children get answers to questions about DNA, environmental clean-up, and even C-H activation. The kids' reporting was part of an outreach event called Science Storytellers that took place during the American Chemical Society National Meeting in San Diego in August. Science Storytellers empowers kids to ask questions as they interact, one-on-one, with real scientists. In this episode, you'll hear from the creator of the Science Storytellers program, Jenny Cutraro, to learn how this outreach activity is...

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...

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...

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...

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.

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...

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...

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...

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...

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...

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...

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...

Even scientists can have superstitions: a lucky shirt, a supernatural paper towel, an elaborate ritual to keep the NMR running smoothly.

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. For a full transcript and...

Our bones contain chemical information about our diet, our behavior, and even our geographic origin.
