Dr Ádám Soós | Revealing the Secret Map Inside Birds That Guides Immune Cells
Deep inside a developing bird’s body, an unassuming organ is hard at work building a sophisticated immune system. Known as the bursa of Fabricius, it is where B cells – the immune cells responsible for producing antibodies – are born and trained. While scientists have long understood its importance, new research is revealing just how finely tuned and dynamic this environment really is. Recent work led by Ádám Soós and Emőke Szőcs at Semmelweis University offers a closer look at how B cells navigate this tiny but complex structure.
Stacking Bacillus Species for Better Performance
If you’re using a probiotic in your animal feed program and it only contains one specie of Bacillus, you may be leaving a lot of performance on the table. Bacillus is a genus of spore-forming bacteria that has proven to be a cornerstone of animal nutrition for decades, and for good reason. The spores are tough enough to survive the heat and pressure of feed pelleting, resist digestive acid, and arrive alive and active in the intestinal tract where the real work happens. Most other probiotic organisms simply can’t make that journey intact.
Dr. Steve Nordeen | A Plant-Inspired Breakthrough for Menopause Relief
Menopause can bring a range of symptoms, including vaginal pain, decreased sexual arousal and recurrent vaginal and urinary tract infections. While estrogen therapies can be very effective at relieving these problems, many people worry about the risks of steroid hormones circulating throughout the body. This has led scientists to search for treatments that work locally where they are needed, without broader side effects. Recent research is pointing to an unexpected source of inspiration: naturally occurring plant compounds.
Professor Kateryna Pierzynowska – Professor Stefan Pierzynowski | Uncovering the Feedback Loop that Could Rewrite Diabetes Science
The pancreas is best known for producing insulin, the hormone that keeps blood sugar in check. But a growing body of research suggests this organ has been hiding a secret – one that could reshape how we understand and treat type 2 diabetes. At the heart of this story is a digestive enzyme called amylase. Normally associated with breaking down starch, amylase is produced by the exocrine part of the pancreas – the side responsible for digestion, as distinct from the insulin-producing side. For decades, these two sides were studied almost in isolation. Kateryna Pierzynowska and Stefan Pierzynowski of Lund University have spent years arguing that this is a mistake.
Dr Brent Iverson | Why a Key COVID-19 Antiviral Is Still Working After Years of Use
When antiviral drugs are widely used, resistance usually follows. Viruses mutate, treatments lose strength, and scientists scramble to adapt. That pattern has been seen with influenza, HIV, and many other infections. When the anti-viral drug Paxlovid was rolled out globally to treat COVID-19, many experts expected that the virus would eventually evolve ways to evade it. But several years on, meaningful resistance has not taken hold. In two closely connected studies, Dr Brent Iverson and colleagues set out to understand why. Their findings suggest that the virus may be more constrained than many had assumed – and that those constraints are helping Paxlovid remain effective.
Dr. Jamie Rausch | Exploring How Fat Tissue Shapes Health Across a Lifetime
For decades, fat tissue was treated as little more than the body’s storage cupboard – a place where excess calories were tucked away for later use. But research from Dr. Jamie Rausch, Assistant Professor of Nursing at Indiana University, is helping to overturn that simplistic view. Fat, or adipose tissue, is now understood to be one of the body’s most active and influential biological systems, constantly sending chemical signals that shape metabolism, inflammation, and long-term health.
Prof. Christian Bär – Dr. Shambhabi Chatterjee | Rewinding the Clock on Lung Disease: A Potential New RNA Therapy for Pulmonary Fibrosis
Pulmonary fibrosis is a devastating disease in which lung tissue becomes scarred and stiff, making it harder to breathe. The outlook for patients remains poor, with many surviving only a few years after diagnosis. Current treatments can slow the damage, but they cannot reverse it. New research by the team of Prof. Christian Bär and Dr. Shambhabi Chatterjee of Hannover Medical School and their colleagues explore a promising alternative – one that works at the level of our cells’ biological ‘aging clock’.
IAPB – Seeds of Innovation: The Science Driving Sustainable Agriculture
Since its beginnings in 1963 as the International Association for Plant Tissue Culture, the International Association for Plant Biotechnology (IAPB) has helped shape the field of modern plant science. The IAPB brings together researchers and innovators from around the world. A major upcoming event is the IAPB 2026 Congress, taking place in Saskatoon, Canada, from July 26–30. Led by Dr. Pankaj Bhowmik, the organization’s 16th President, the Congress will welcome over 300 participants from more than 30 countries.
Rob Onyenwoke | How Vaping Can Make Your Lungs More Vulnerable to Infection
Electronic cigarettes have been marketed as a safer alternative to traditional tobacco, but a growing body of research is painting a more troubling picture. Two studies from North Carolina Central University, conducted by Rob Onyenwoke and colleagues, suggest that vaping doesn’t just harm the lungs on its own – it may also make them far more vulnerable when infection strikes.
Dr. Xiaolei Zhu – Dr. Barbara Slusher | A New Approach to Depression Treatment Targets Brain Immune Cells
Depression affects nearly one in five Americans at some point in their lives. Sadly, for roughly a third of patients, standard antidepressants simply don’t work. Now, researchers at Johns Hopkins University School of Medicine believe they may have found a promising new path forward – one that targets the brain’s own immune cells. Dr. Xiaolei Zhu, Dr. Barbara Slusher, and their colleagues have been investigating why the brain’s resident immune cells, called microglia, appear to go into overdrive in people with major depressive disorder.
Dr Vedrana Bali – Dr Vladimir Grubišić | How Enteric Glia Shape Health and Disease
The human gut is more than a long tube for digesting food – it is one of our body’s largest and busiest borders, constantly deciding what may enter and what must stay out. Most of these decisions are made by a nervous system embedded within the gut wall, often called ‘the brain in the gut’, and supported by the local immune system. When this border becomes too permeable, often described as a ‘leaky gut’, problems can arise throughout the body. Researchers Vedrana Bali and Vladimir Grubišić, at the New York Institute of Technology College of Osteopathic Medicine, argue that this leaky-gut phenomenon may cause far more than stomach troubles.
Professor Stefan Pierzynowski – Professor Kateryna Pierzynowska | Cracking the Code on How Our Bodies Absorb Protein
When you eat a steak or a protein shake, what actually ends up in your bloodstream? It turns out the answer is surprisingly little-understood – until now. Professors Stefan Pierzynowski and Kateryna Pierzynowska of Lund University, also affiliated with the Institute of Rural Medicine, Lublin, and The Kielanowski Institute of Animal Physiology and Nutrition, have developed a clever new approach to answer this question. Their work has important implications for how doctors treat digestive diseases and how to evaluate dietary proteins’ quality and bioavailability.
