Could a cheaper, more environmentally friendly refrigerant already exist, and could corporate lobbying be helping keep it out of American air conditioners? Why did the chemicals once hailed as safe alternatives become environmental villains, and are their replacements actually much better? Melissa and Jam follow the twisty history of Freon, ozone depletion, greenhouse gases, propane, and air-conditioning regulations to find out why choosing a refrigerant is never as simple as “this one works.” Grab

The discovery of sex hormones in the 1930s led to the development of female birth control, a widely used class of drugs that reshaped cultural norms surrounding fertility and bodily autonomy. But contraception remains largely the responsibility of women. On today’s episode: the evolution of birth control and the future of male contraception.

t’s about time we give you another peak into our vanity shelves! This week we are telling you our favorite skin and hair care products under $30 (well almost, we need to make one exception for Sadie). As cosmetic formulation chemists we have tried a lot of different products, and are very familiar with all types of ingredients. Join us in the Science Salon for 10 products we are currently obsessed with. And we know how hard it can be to trust ‘influencers’ but don’t worry, we are scientists. We have

Is Covid back? National and regional COVID-19 activity is increasing, but acute respiratory illness causing people to seek healthcare is very low. As of August 19, 2026, CDC estimated that infections were growing or likely growing in 47 states. Here the details in 6 minutes so you know what to look out for.

In this episode, we discuss the changes to science policy made by the new UK prime minister and breakdown the chemistry behind crumbling concrete in Ireland. On July 21, new UK Prime Minister Andy Burnham abolished the government's department of science and absorbing its functions into the business department. What does this mean for UK research?  And, thousands of Irish buildings are cracking apart, but the culprit may not be what scientists first thought. We discuss the mica crisis and the

I næsten 30 år arbejder kemikeren Otto Hahn og fysikeren Lise Meitner side om side og bliver et af videnskabens stærkeste makkerpar. Da den jødiske Meitner tvinges på flugt fra Nazityskland, kunne det ligne et punktum. Men de fortsætter i al hemmelighed deres samarbejde på afstand - og ender med en opdagelse, der forandrer verdenshistorien for altid. En opdagelse, der dog samtidig skal splitte de to gamle venner i spørgsmålet om, hvem der egentlig fortjener æren.  Afsnittet er skrevet, tilrettelagt

What happens when textbook theory meets the unpredictable reality of an operational chemical plant?In this episode, Dr. Peter Clark is joined by Dr. Linda Cotter, Senior University Teacher in Chemical Engineering at the University of Sheffield, to explore why traditional engineering education often leaves graduates underprepared for the plant floor—and how we can fix it. Drawing from her international academic career across South Africa, Australia, and the UK, Dr. Cotter breaks down the hidden

Reports about the impacts of datacentres, including carbon emissions, water usage and power consumption, vary drastically and the truth can be hard to decipher. Deborah Andrews, Emeritus Professor at London South Bank University, joins us for some myth busting. Plus, science journalist Caroline Steel has been scouring the journals and brings us some of this week’s most exciting science news, including the failed attempts to save the Swift space telescope. Presenter: Tom Whipple Producers: Alex

Every summer, high in the Himalayas, a dark resin oozes out of sun-baked cliff faces. Locals call it "rock sweat." For over a thousand years it's been used in Ayurvedic medicine — and lately it's exploded across social media as a testosterone-boosting, energy-giving "ancient superfood." This week, Dr. Dan puts shilajit under the microscope.We break down what shilajit actually is at the molecular level: a geological exudate formed over centuries as plant matter decomposes

In this episode of Concentrating on Chromatography, host David Oliva is joined for the first time by co-host Candice (Candi) Gokey — PhD candidate at UC San Diego / San Diego State University and expert in LC-MS/MS method development for untargeted metabolomics to interview Jacob Russell, a third-year PhD student in the Riley Research Group at the University of Washington (Seattle).Jacob's research sits at the frontier of mass spectrometry based intact glycoproteomics, where the goal is to keep

What happens when a chemist ventures onto Reddit to answer the internet’s most pressing science questions? Why does carbon get its own entire branch of chemistry, what makes fireworks burn different colors, and can an invention work even when its inventor has no idea why? Melissa and Jam tackle those mysteries, plus laboratory disasters, stress recovery, wireless charging, and one surprisingly complicated “Am I the Jerk?” dilemma. It’s chemistry support for the internet, because Reddit clearly has

Through a few serendipitous discoveries, antibiotics changed the course of history by turning deadly infections into manageable sicknesses. But it didn’t take long for bacteria to begin outsmarting these wonder drugs. On today’s episode: The fascinating world of antibiotics and the efforts to tackle antibiotic resistance, including using AI to come up with new drugs that will only become more essential.
