Globalization was once expected to make national borders less important. As money, technology, data, and trade flowed more freely across countries, many believed governments would gradually lose some of their ability to control events beyond their own territory. Instead, something rather different has happened. Powerful states have found new ways to extend their influence, using access to financial systems, technologies, markets, and critical infrastructure to enforce their national laws far beyond their own borders. In recent years, similar patterns have appeared in areas ranging from international sanctions to technology regulation and environmental policy.

So far, most attempts to model dark matter have relied on assumptions that may not capture its full behaviour, potentially undermining the constraints that astronomers thought they had already established. For the first time, Dr Tomislav Prokopec at Utrecht University, together with his former master's student Marco Vecchioni, have developed a framework that treats dark matter as a fully quantum field – building on earlier work showing that gravitational waves in the early universe are similarly unaffected by their quantum surroundings. Their findings suggest that several widely-assumed constraints on dark matter may need to be fundamentally reconsidered.

The work of Dr. Gary Blau and Dr. Kyle Stephens of Temple University, Philadelphia, Pennsylvania, USA asks an important question that is becoming increasingly relevant around the world. If the workplace has fundamentally changed, shouldn't the way we measure employee deviant work behaviour change too? Their research argues the answer is yes because the consequences reach far beyond academic debate. Traditional work behaviour deviance examples include: someone deliberately arrives late, spending long coffee breaks chatting with colleagues, or working more slowly than usual. Others are spreading rumours, bullying coworkers, or damaging company property. These are the kinds of in-person, on-site deviant behaviours researchers have investigated, that is, why employees sometimes act against the interests of employing organisations.

Every healthcare professional involved in the care of patients with chronic obstructive pulmonary disease understands the challenge. COPD is one of the world's leading causes of illness and death, affecting more than 300 million people and placing an enormous burden on healthcare systems. Although treatment options have improved significantly over recent decades, clinicians continue to face a fundamental problem. They mostly rely on diagnostic measurements that do not fully capture the disease's complexity. For many years, a simple form of spirometry has been the cornerstone of COPD diagnosis and management. The ratio of forced expiratory volume in one second and forced vital capacity is relatively easy and inexpensive to measure. It is therefore widely available and is supported by decades of clinical experience. This ratio has become so firmly established as a measure of the disease that it is virtually impossible to imagine COPD assessment without it.

For decades, doctors have puzzled over a strange and often misunderstood condition called normal pressure hydrocephalus. People with the disorder may begin to shuffle when they walk, struggle with memory, or lose bladder control. Brain scans reveal enlarged fluid-filled spaces called ventricles, yet the pressure inside the skull often appears surprisingly normal. It is a medical paradox that has challenged neurologists and neurosurgeons since the condition was first described in the 1960s. Now, new research is offering a radically different way of thinking about what may actually be happening inside the brain. Rather than viewing normal pressure hydrocephalus as a simple problem of fluid buildup, researchers are beginning to see it as a disorder of energy, rhythm, and pulsation.

When most of us imagine a flood, we think of destruction, displacement, and recovery. Few would imagine that some of nature’s smallest creatures see floodwaters not only as a threat but also as an opportunity. Among these remarkable survivors is the red imported fire ant, an invasive species that has become one of Australia’s most closely monitored pests. Fire ants are notorious for their painful stings and their ability to spread rapidly across landscapes. Native to South America, they have successfully established themselves in several countries around the world. In Australia, where authorities have invested heavily in an ambitious eradication program, understanding how these ants move and survive is critical. One of the most fascinating questions researchers have explored is whether floods help fire ants spread into new territory. The answer turns out to be more complicated than many people might expect.

When a new medical test reaches a clinic or laboratory, most people focus on the technology itself. They think about the machine, the test kit, or the scientific breakthrough that makes diagnosis possible. Yet behind every successful diagnostic test lies something far less visible but equally important: the biological specimens used to develop and validate it. Without the right samples, even the most promising diagnostic innovation can fail. A test may appear accurate in the laboratory but perform poorly in real-world settings. It may work well for one patient population but struggle in another. It may detect a disease in some regions of the world while missing important variations elsewhere.

For centuries, sleep has remained one of humanity’s greatest biological mysteries. We spend roughly a third of our lives doing it, yet scientists are still trying to fully understand why the brain insists upon sleep. It seems clear that sleep restores the body, sharpens memory, regulates emotions, and keeps countless internal systems in balance. But one major problem has always complicated sleep research: most experiments focus on what happens when sleep is taken away. That approach has taught researchers a great deal. Sleep deprivation has been linked to poor concentration, weakened immune function, emotional instability, and a long list of health problems. Yet asking what happens when sleep is removed only tells part of the story. It is a little like studying hunger by starving people without ever exploring what happens when they are exceptionally well fed.

The human heart beats with a rhythm so steady that most of us rarely stop to consider it. Each pulse carries oxygen, sustains life, and quietly reflects the intricate biological systems that keep us alive. However, this familiar rhythm requires a delicate electrical balance. When that balance is disturbed, the consequences can be sudden and severe. Among the most striking examples is Long QT syndrome, a condition that can lurk silently until it triggers a dangerous arrhythmia or even sudden cardiac death.
