Environmental pollution in densely populated regions remains a persistent challenge, particularly where cultural, religious, and social practices intersect with fragile ecosystems. While industrial emissions and vehicular pollution have received substantial scholarly attention, the environmental impact of everyday ritual and community practices

Have you ever intended to check a single notification, only to realize forty minutes have vanished into an endless scroll? In 2026, privacy is no longer just about your data; it is about your thought process. Is your next choice truly yours, or has a 'Digital Twin' already made it for you

We begin with things - particles, fields, forces - and then build laws and equations to explain how those things behave. This approach has been extraordinarily successful. It is how we arrived at quantum mechanics, general relativity, and the Standard Model.

You probably know this story: Aurora, also known as the Sleeping Beauty, was a kind princess who was cursed by an angry fairy and fell into a deep sleep for years. On her sixteenth birthday, she pricked her finger, and the spell came true. Silence covered the land, and the entire kingdom fell asleep with her. Years later, the spell could be broken by a kiss from a prince.

Symptoms of anxiety disorders can interfere with daily life activities, such as performance at work, being in social gatherings, and relationships. In severe cases of anxiety, there might be a feeling of intense fear in common situations, a preference for isolation, or a refusal to leave their homes

Out of so many mental disorders, a rare disorder is the Fregoli delusion or Fregoli syndrome (FS), in which an individual holds a delusional belief that different people are in fact a single person, who keeps on changing appearances quickly or is in disguise. People affected with this condition often experience anxiety, paranoia, and agitation. It can impact the patient’s mental health and their safety and the safety of others.

Tiny but powerful, basement membranes support cells, regulate barriers, and drive disease when disrupted—key players in health, aging, and cancer.

Many physical and computational systems exhibit a familiar behavior: ordered states gradually decay in the presence of noise. Examples appear across science:

Many times, individuals feel fearful or extremely worried about cancer testing. The regular tests and scans that patients living with any cancer diagnosis have to undergo, to monitor their condition, can make them feel anxious before, during, or after a scan or a follow-up test

Discover how antigen-presenting cells like dendritic cells and macrophages are being recruited through smart particle design for vaccines and immunotherapy.

In this study, I explore how cancer risk is distributed across the animal kingdom, emphasizing the role of life-history traits, reproductive strategies, and social behavior in shaping susceptibility to disease. Drawing on recent findings in comparative oncology, the article examines patterns that challenge traditional assumptions, such as the relationship between body size and cancer, and highlights evolutionary mechanisms that may confer resistance in certain species.

In many areas of physics, the word “singularity” implies the breakdown of equations — an undefined point where the mathematics “fails” or where physical laws suddenly stop working. But this interpretation has always felt philosophically unsatisfying. Why should nature permit a point where its own rules dissolve?

The human ear is often described as one of the most sophisticated sensory systems in biology. Within a structure no larger than a seashell, the auditory system can detect frequencies ranging from the faint rumble of distant thunder to the subtle harmonic texture of a violin string

The event horizon of a black hole imposes a fundamental constraint: once matter and information cross it, ordinary recovery of structure through dissipation and re-equilibration becomes dynamically unavailable to external observers.

Depression has affected humans for hundreds of years. Symptoms can include persistent feelings of sadness, sleep disturbances, anxiety, and a loss of interest in social activities. Science doesn’t yet fully understand the causes and effects, but here’s what we do know: the brain is a powerful organ, and it is capable of change. Made up of a wide network of connections, it relies on chemicals, electrical impulses, and billions of neurons. Let’s explore how brain science

Relational Dominance: A Testable Structural Hypothesis for Navier–Stokes Turbulence

Evolution is often imagined as a process that unfolds over millions of years. However, in microorganisms such as yeasts, evolutionary changes can occur much more rapidly. Yeasts reproduce quickly, populations grow to large sizes, and genetic variations can spread through generations in a short time.

This architecture is essential for shielding neurons from toxins, pathogens, and fluctuations in the bloodstream, but it also creates a devastating bottleneck for modern medicine. More than 98% of small-molecule drugs and nearly all large biological therapeutics fail to cross the BBB in meaningful amounts, leaving many promising treatments for neurodegenerative disorders, brain tumors, and inflammatory diseases stranded in the circulation.

What allows anything stable to exist at all? Before objects, laws, or equations can be described, something more basic must occur: something must persist long enough to be identified. This shifts the focus from what exists to the conditions under which anything can exist stably.
