Infrasound refers to infrasound waves below 20 hertz (Hz), which are generally above the range of human hearing. These vibrations can come from human sources such as traffic and industrial equipment, as well as natural phenomena such as storms. In the animal world, some species rely on infrasound to communicate, while others actively avoid it. When scientists investigated whether people can perceive infrasound, they found that we are not consciously aware of it. But our bodies still react. Exposure is associated with increased irritability and elevated levels of cortisol, a hormone associated with stress. “Infrasound is pervasive in everyday environments,…
Spending time in natural light during regular work hours tends to better maintain blood sugar levels and burn more body fat in people with type 2 diabetes. This metabolic change provides evidence that environmental lighting plays an important role in the management of chronic health conditions. The results of this study were recently published in the journal cell metabolism. “We are working in the field of type 2 diabetes, especially the metabolic aspects of type 2 diabetes,” said Patrick Schrauwen, a researcher at the Institute of Clinical Diabetes at the German Diabetes Center. The human body relies on circadian rhythms,…
Researchers at APC Microbiome Ireland, a leading research center at University College Cork, have taken a major step towards understanding what coffee does for the body. For the first time, scientists have taken a closer look at how coffee interacts with the gut-brain axis, the communication network that connects the digestive system and the brain. The survey results are nature communications Supported by the Institute for Scientific Information on Coffee (ISIC), research shows that drinking both caffeinated and decaf coffee regularly shapes the gut microbiome, which can influence mood and stress. How coffee affects your gut microbiome and mood Coffee…
A new study published in the journal PLOS One reveals that a person’s underlying personality traits are strongly related to how often they experience sexual fantasies. The findings suggest that people with high levels of negative affectivity fantasize more often, whereas people who are highly agreeable or conscientious tend to have fewer sexual fantasies. When psychologists try to understand why people behave the way they do, they often look to the Big 5 personality framework. This theoretical model asserts that human personality can be primarily described using five broad dimensions. Extraversion describes a person’s sociability and sociability, while agreeableness reflects…
The hippocampus plays a central role in how we form memories and move through space. This helps transform short-term experiences into long-term memory, allowing you to save and build on what you’ve learned. Scientists led by Peter Jonas, the Magdalena Waltz Professor of Life Sciences at the Austrian Institute for Science and Technology (ISTA), are closely studying this area of the brain. Their new research nature communicationsLet’s explore how one of the major neural networks in the hippocampus develops after birth. Imagine a completely empty piece of paper. Start writing there and gradually fill it with information. This idea reflects…
In a groundbreaking study recently published in the Journal of Exposure Science and Environmental Epidemiology, researchers have uncovered a new approach to monitoring environmental pollution through an innovative capillary blood collection device. This cutting-edge technology was applied to a cohort of veterans living near potential sources of per- and polyfluoroalkyl substances (PFAS), which are notorious for their persistence in the environment and suspected health effects. This study represents a significant advance in biomonitoring technology and addresses the critical need for minimally invasive, accurate, and field-deployable tools to assess human exposure to these hazardous compounds. PFAS are sometimes referred to as…
Quantum mechanics is famous for its strange and often counterintuitive ideas. At very small scales, particles do not behave like everyday objects. Instead, they can exist in multiple states at once, a concept known as superposition. Physicists describe this behavior using a mathematical object called a wave function. However, this picture conflicts with what we observe in everyday life, where objects occupy one distinct place or state at a time. To solve this, scientists typically propose that when a quantum system is measured or interacts with an observer, its wavefunction collapses into a single result. Now, with support from the…
Virtual “girlfriend experience” platforms may be booming because they offer people easy and customizable access to intimacy in a way that appeals to our deepest psychological urges for connection, attraction, and control. This is the central argument of a new review published in the June 2006 issue. evolutionary psychology. Désirée Popelka and colleagues provide an extensive theoretical explanation of how intimacy has changed with technology. They track girlfriend experiences (GFEs), from in-person escort services to online platforms like OnlyFans, and more recently, AI companions. What unites them all, across all eras and formats, is the simulation of a romantic relationship:…
The 2025-2030 Dietary Guidelines introduce major changes like higher protein intake, full-fat dairy emphasis, and curbs on ultra-processed foods. Dive into the science, critiques, and clinical applications for metabolic health.
In a new study, SFI professor David Wolpert, SFI fractal faculty member Carlo Rovelli, and physicist Jordan Scharnhorst take a new look at a famous and disturbing idea in physics and cosmology known as the “Boltzmann brain” hypothesis. This concept suggests that our memories, perceptions, and observations may not reflect the actual past at all. Instead, they may have formed randomly through fluctuations in entropy, giving the appearance of a consistent history that never actually happened. This puzzle arises from deep tensions in statistical physics. An important foundation for understanding why time appears to move in one direction is Boltzmann’s…
