Dr Indira Narayanan | How Unnecessary Neonatal Unit Admissions Affect Families and Overstretch Care Systems
In many hospitals around the world, the neonatal unit is seen as the safest place for a newborn baby who needs anything more than basic care provided in the postpartum unit. Yet this well-intentioned reflex to protect a baby “just-in-case” can carry hidden costs. A new study led by Dr Indira Narayanan, neonatologist and researcher at Georgetown University Medical Center, suggests that a small but impactful number of babies admitted to neonatal units may not actually need intensive care at all. Instead, these admissions can increase pressure on already stretched units, especially in low-and middle-income countries, separate mothers from their babies, and unintentionally undermine breastfeeding efforts.
Prof. Debra Zoran | After the Storm: Protecting Companion Animals in Crisis
When disaster strikes, the images that dominate news coverage are almost always human centered. We see flooded neighborhoods, collapsed buildings, families waiting in shelters, and exhausted first responders. Yet woven into nearly every one of those scenes is another presence, often trembling at the end of a leash or peering out from a carrier. Companion animals are not an afterthought in modern life. They are family members, sources of emotional stability, and in some cases essential partners such as service dogs. As natural and human-made disasters grow in frequency and severity, the question of how to protect people inevitably includes the question of how to protect their animals.
Dr. Jeddah Marie Vasquez | Blending Biology and Engineering to Repair Damaged Nerves
When a peripheral nerve is badly damaged due to injury, the consequences can be life-changing. Hands that no longer feel heat or cold, muscles that will not respond to the brain’s commands, and pain that lingers for years are all common outcomes. Surgeons can sometimes stitch nerves back together, but when there is a section of nerve missing entirely, repair becomes far more complex. For decades, researchers have been trying to build better bridges for injured nerve axons to cross. A new interdisciplinary research effort led by Dr. Jeddah Marie Vasquez and Dr. Vijay Kumar Kuna of Research Institutes of Sweden, and their collaborators from Umeå University (Associate Professor Paul Kingham) and University College London (Professor James Phillips), bring together polymer chemistry, materials science, and cell biology to rethink what such a bridge could be made of – and how it might one day be tailored to individual patients.
Dr. Huda Makhluf | The Long Shadow: The Science Behind Long COVID
Four years after the first lockdowns and daily case counts faded from headlines, COVID 19 continues to shape lives in quieter but deeply disruptive ways. For millions of people around the world, the virus did not simply end with a negative test. Instead, it left behind a complex and often invisible condition known as long COVID. This lingering illness challenges how medicine understands recovery, chronic disease, and the long reach of viral infections. In a comprehensive review, Dr. Huda Makhluf of the National University in San Diego, and her colleagues, synthesize what scientists currently know about long COVID and what remains frustratingly uncertain.
Prof. Dr. Christopher Gerner | Ulcerative Colitis and the Hidden Logic of Chronic Disease
Ulcerative colitis, often called UC, is a chronic inflammatory disease of the large intestine that is becoming more common across the world, including among teenagers and young adults. For many patients it begins with subtle warning signs such as abdominal discomfort, diarrhea, fatigue, or traces of blood in the stool. Over time these symptoms can escalate into painful and frightening flare-ups that disrupt education, careers, family life, and emotional well-being. Although modern medicine has become remarkably effective at calming these acute disease episodes, UC remains stubbornly persistent. In most patients the disease returns after periods of apparent recovery, sometimes without any obvious external trigger.
Professor François Vialard | Unraveling Azoospermia: Using Genetics to Avoid Futile Sperm Extraction
For many couples struggling to conceive, a male infertility diagnosis can feel like a closed door. Roughly half of all infertility cases worldwide stem from male factors, and among these, one of the most frustrating conditions is non-obstructive azoospermia (or NOA for short), a complete absence of sperm caused not by a physical blockage but by a failure of sperm production itself. Until recently, most men with NOA were offered a potentially painful and uncertain procedure called testicular sperm extraction (or TESE). In this surgery, doctors search directly within the testis for a few viable sperm cells that can be used for in vitro fertilization. When successful, the results can be life-changing. When unsuccessful, it is physically invasive, emotionally draining, and often repeated several times in vain.
Prof. Jim Oates | When Blood Vessels Speak: How Lupus Turns the Body’s Gatekeepers into Active Messengers of Inflammation
You may imagine your vasculature as a vast and silent network of tubes, dutifully carrying blood, oxygen, and nutrients to every organ and tissue. These vessels seem purely mechanical, like plumbing hidden behind walls, doing their job quietly and invisibly. Yet modern biology has revealed a far richer and more surprising reality. Blood vessels are lined with living, sensing, responding cells called endothelial cells, and these cells are anything but passive. They listen to chemical signals, respond to stress, regulate traffic, and communicate constantly with the immune system.
Prof. Stephen Graham | From Hospitals to Households: How Decentralised Care Is Transforming Tuberculosis Treatment for Children
Tuberculosis remains one of the world’s oldest and most stubborn infectious diseases, yet the way health systems respond to it is often dogged by modern challenges. Clinics are overcrowded, families must travel long distances, and children with vague or non-specific symptoms are frequently overlooked. For decades, tuberculosis care has been organised around hospitals and specialised facilities, even though the disease itself spreads and takes root in homes and communities. A growing body of research now argues that this mismatch is costing lives, particularly among children. Decentralised models of care, which bring services closer to families and empower community-based health workers, offer a compelling alternative. Recent evidence from multiple settings shows that when tuberculosis care is shifted out of distant clinics and into neighbourhoods and households, access expands with potential to close the current gaps in TB detection, treatment outcomes and prevention that benefit communities and families, including their children.
Dr. Jürgen Gailer | Linking the Blood Chemistry of Metals with Adverse Human Health: New Tools Reveal an Invisible World
Researchers Maryam Doroudian and Jürgen Gailer from the University of Calgary explore what happens when red blood cells rupture and release a zinc-containing enzyme called carbonic anhydrase 1 into the bloodstream, revealing that it remains unexpectedly free and may influence vascular health. Their work also connects to broader research showing how liquid chromatography is transforming our ability to study toxic cadmium and mercury as they move through the body. Together, these studies uncover hidden biochemical processes that shape how environmental pollutants and blood-cell damage affect human health.
Easing the Hardest Moment: How Brain Stimulation Is Transforming Care for People with Opioid Use Disorder
In the world of opioid addiction treatment, the hardest moment often arrives precisely when hope begins to emerge. It is the moment someone chooses to stop using opioids. That decision, courageous and life-changing, almost immediately collides with one of the most punishing physiologic syndromes known in medicine: opioid withdrawal. Withdrawal brings waves of nausea, sweats, shaking, cramps, insomnia, anxiety, and extremely intense cravings. For countless individuals, this moment is a seemingly inescapable stumbling block that can be the undoing of their recovery. They want to stop, they mean to stop, but withdrawal can become an insurmountable barrier.
Dr. Rasha Bayoumi | Decolonizing Global Collaboration: Building Equitable Science Diplomacy
Science diplomacy, meaning the use of scientific collaboration to strengthen international relations and address shared global challenges, has long been hailed as a force for good. Yet, as Dr. Rasha Bayoumi of the University of Birmingham Dubai and her colleagues argue in their Editorial for a special issue in the journal Frontiers in Public Health, this optimism often masks uncomfortable realities. The practice of science diplomacy has too often reproduced the very inequalities it aims to dismantle, operating within frameworks that privilege powerful nations and institutions while marginalizing voices from the Global South.
Lighting the Path: How the GlioLighT Consortium Is Exploring New Ways to Treat Brain Tumours
Across the world, scientists are still trying to answer one of medicine’s most difficult questions: how can we safely and effectively treat brain cancers such as glioma? Despite decades of effort, outcomes for people diagnosed with high-grade glioma remain bleak. Current treatments, including surgery, radiotherapy, and chemotherapy, can slow the disease, but rarely stop it. The GlioLighT consortium, a multidisciplinary European research team funded by the European Innovation Council, has come together to explore a novel approach based on direct light therapy. Being in a very early stage, the project doesn’t promise an immediate cure; instead, it sets out to answer a very fundamental question: can light itself trigger biological processes that might form the basis of a safe and targeted brain tumor therapy?
