In the years since the wars in Iraq and Afghanistan, many military veterans have carried home an invisible burden. Blast-related mild traumatic brain injury, often called blast-mTBI, has been described as the signature injury of those conflicts. It is labeled mild, yet for many who experience it, the consequences are anything but. Veterans report persistent headaches, sleep disturbances, memory lapses, mood changes, irritability, and difficulties with concentration and decision making. These symptoms can linger for years, affecting relationships, work, and overall quality of life.

What does it really mean to act or feel on behalf of another person? The phrase is familiar in everyday life. Parents apologise on behalf of their children, lawyers speak on behalf of their clients, and friends feel anger or pride on behalf of those they care about. These cases seem ordinary, yet they raise difficult questions. Whose action is this, exactly? Whose feeling is being expressed? And what sort of relationship makes this kind of representation possible? In his paper “On Behalfness: Siding with Others in Action and Emotion,” philosopher Prof. Neil Roughley at the University of Duisburg-Essen in Germany argues that these everyday practices reveal a distinctive form of alignment between people that deserves careful philosophical attention.

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.

Over the past two decades, materials science has been quietly transforming the technological foundations of everyday life. While consumers notice faster phones and more capable computers, the deeper story unfolds at the scale of atoms. Scientists are learning how to isolate and control materials that are only a few atoms thick, revealing forms of matter whose behavior differs profoundly from their bulk counterparts. These so-called two-dimensional materials promise a new generation of electronics, sensors, and photonic devices. At the same time, they challenge long held assumptions about stability, reliability, and control at the smallest scales. Researchers such as Prof. Abdullah Alrasheed of the King Abdulaziz City for Science and Technology are helping to expand our knowledge and push the boundaries of what is possible in this sphere.

What if the most honest way to speak about God today is to begin by admitting that the old images no longer work? For centuries, many believers pictured God as a supreme being who rules the universe from beyond it, guarantees meaning, and stands as the ultimate explanation for everything that exists. Yet modern history, philosophical critique, and even theology itself have steadily eroded this picture. The result is not simply atheism in the popular sense, but a profound theological crisis.

In rivers and lakes across North America, fish carry secrets invisible to the naked eye, secrets that researchers with the U.S. Geological Survey’s Eastern Ecological Science Center are determined to help uncover. With a passion for aquatic health and an interest in viral sleuthing, these researchers, including Dr. Clayton Raines, a fish biologist, have conducted groundbreaking research that is reshaping our understanding of fish disease. From uncovering a new virus in alewives to decoding the mystery behind the blotchy skin of black basses, this work not only expands the frontiers of fish virology but also reveals the hidden complexities of ecosystems. Here, we explore Raines’ and colleagues’ fascinating findings and their implications for fish management, conservation, and the health of freshwater species.

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.

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.

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.

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.
