Pomegranate’s deep red color and famously stubborn stains come from more than visual drama—they reflect the fruit’s unusual chemistry. Its signature compound is punicalagin, a large polyphenol concentrated mainly in the peel, pith, and membranes. Yet punicalagin itself is barely absorbed by the body. More than 90 percent travels to the colon, where certain gut bacteria transform it into smaller, absorbable compounds called urolithins. Urolithin A is the metabolite attracting the most scientific

Is AI really plotting against us? In a week where an Anthropic researcher believes there is more than a 10% chance AI 'could kill all humans' we're delving deeper into the capabilities of AI agents. Tom Whipple is joined by Alex Mallen, from Redwood Research, the team whose recent investigation exposed the surprising, weird, and worrying scale of a website hack conducted by OpenAI agents.Is this the most important story we will ever cover on Inside Science? Or is this all just credulous sci fi hype

How much should scientific literature actually influence your clinical decisions—and how do you know which dental research to trust? In Episode 48 of Bonding & Beer, Dr. Rolando Nuñez explores how scientific literature shapes clinical decision-making in dentistry, from understanding evidence-based dentistry to recognizing the important differences between in vitro research and clinical studies. With new research constantly being published, and studies sometimes reaching conflicting conc...

If you take a handful of dirt from the roadside, it contains PFAS. The challenge isn't finding forever chemicals — it's finding all of them. Standard monitoring methods cover 40 to 50 PFAS species. Thousands more go completely unmeasured. That's the gap Dr. Viktoria Müller has spent her career trying to close.Viktoria is a postdoctoral researcher at the University of Graz specializing in PFAS environmental fate, transport, and the fluorine mass balance. Her work spans ski slopes, rivers,

This study guide deconstructs lipid biochemistry by examining the reciprocal regulation of catabolic (kat-uh-BAH-lik: breakdown) and anabolic (an-uh-BAH-lik: building) acyl (AY-sil) pathways, centering on the carnitine (KAR-nih-teen) shuttle and allosteric (al-oh-STEER-ik: enzyme-regulating) control via malonyl-CoA (MAL-uh-nil koh-AY). We clarify the compartmental and enzymatic divide governing hepatic (heh-PAT-ik: liver) ketogenesis (kee-toh-JEN-eh-sis) versus peripheral ketolysis

The Dr. Joe Show can be heard every Sunday on CJAD 800 at 3pm.

Elastic rubber, the smell of burning matches, the smoke above a battlefield, hot volcanic breath, God’s punishment, and unquenchable flames of Hell. What do these have in common? Sulfur! The beautiful yellow element behind it all, in today’s episode.

What exactly is a swamp cooler, and why can it beat the heat in Arizona but leave you sweaty and betrayed in Houston? How can an air conditioner run on water, what does humidity have to do with its effectiveness, and could an icy new invention help prevent overloaded power grids? In the final installment of our air-conditioning series, Melissa and Jam explore evaporative cooling, ancient climate-control tricks, and some promising innovations for a hotter world. It turns out “It’s not the heat, it’s

In the late 1950s, a tuberculosis drug was repurposed as the world’s first antidepressant. Then the selective serotonin reuptake inhibitor (SSRI) Prozac ushered in a new era of antidepressants. Today SSRIs are some of the most widely prescribed drugs in the country, but gaps still exist in our biological understanding of mental health, the overall efficacy of antidepressants, and predicting serious side effects. In response, some scientists and physicians are turning to different classes of d...

Summer isn’t over yet! We have stressed the importance of sunscreen, but how does the sun affect your hair? In this episode we are breaking down the science of UV damage, visible light, melanin, and why some hair fades or weakens faster in the sun. Have you ever wondered if your hair needs sunscreen? Tune in, this episode is for you.Welcome to Beauty by the Beaker, the podcast where Sciences Gets a Hot New Makeover! We're two cosmetic chemists who want to reveal what really goes into your

In this episode of Innovate and React, I welcome my former PhD mentor, Dr. Thomas Seidensticker from TU Dortmund, to explore how oleochemistry can provide a sustainable, locally grown alternative to crude oil for the chemical industry. While the traditional chemical sector relies heavily on cheap fossil fuels, plant oils naturally offer closely related hydrocarbon chains that can be functionalized for everyday products like surfactants, cosmetics, and polymers. However, shifting away from crude oil

En glemt petriskål. En smule mug. Og en fejl, der kunne være endt i skraldespanden.I stedet blev den begyndelsen på en af medicinhistoriens største opdagelser. Alexander Fleming opdagede penicillinen – og et nyt våben mod de bakterier, der i århundreder havde kostet millioner af menneskeliv.Men historien om Fleming handler ikke kun om et tilfælde. Den handler om en distræt og nysgerrig forsker, der gennem et helt liv skulle opdage, at de største gennembrud nogle gange gemmer sig i de mindste

Brazil nuts are among the Amazon rainforest’s most remarkable foods. Botanically, they are seeds packed inside heavy, coconut-like pods that fall from trees towering more than 130 feet above the forest floor. Nearly all commercial Brazil nuts are still gathered from the wild because the trees depend on an intricate ecological partnership among specialized orchid bees, rainforest orchids, and seed-dispersing agoutis. This makes their harvest a rare “standing forest” economy—one in which healthy,

Following our discussion of enzyme kinetics, this MCAT study guide traces the path from DNA replication to a functioning protein. It reviews replication-fork mechanics, proofreading and DNA repair, promoter and enhancer regulation, and wobble in the genetic code. Most importantly, it explains how a single nucleotide change can alter a protein’s structure—and potentially change its K_m, V_{\max}, or both.

The quest for Dark Matter just got interesting. Researchers on an international project called the Lux-Zeplin (LZ) Dark Matter Experiment reported they may have discovered the signature of a bit of Dark Matter passing through an underground mine in South Dakota. Kimberly Palladino, professor of physics at Oxford and a member of that LZ collaboration, speaks with Roland to explain how dark matter is being detected. Probiotics have long been all the rage in health advice, but this week we discovered

In this episode of Speciality Sessions, Natasha Klymczuk is joined by Fenna van Zanten, Global M&A Director at IMCD, business division leader and member of its Executive Committee.Fenna’s career has taken her from corporate law and advising on transactions to working inside the business, where her responsibilities now span M&A, integration, commercial leadership and people management.They explore why successful integration cannot simply be reduced to executing a playbook.

The Intermountain Milk Process Association (IMPA) marked its 100th annual conference this year in Sun Valley, and Jon Goodman and Scott Brown are back to recap the highlights. Protein dominated the conversation throughout the event, from GLP-1 driven changes in household consumption to a wave of new investment in premium whey production. Jon and Scott break down what they heard from economists, consumer trend experts, and dairy processors alike.What You'll Learn:Why protein was the biggest topic of
