  Kinesiology, the scientific study of human movement, is a multidisciplinary field that integrates principles from anatomy, physiology, biomechanics, and neuroscience. It examines how the body moves, the forces that act upon it, and the underlying mechanisms that control movement. By understanding these principles, professionals in various fields, including physical therapy, sports science, and occupational therapy, can enhance human performance, prevent injuries, and improve rehabilitation strategies. 
  The origins of kinesiology date back to ancient civilizations, where scholars like Aristotle and Galen first explored the mechanics of movement. However, the field gained prominence in the 19th and 20th centuries as scientific advancements allowed for a deeper understanding of biomechanics and motor control. Today, kinesiology encompasses a vast range of topics, from the microscopic study of muscle fibers to large-scale analyses of athletic performance. 
  One of the core components of kinesiology is biomechanics, which applies the principles of physics and engineering to study how forces influence movement. Biomechanics helps explain how the body maintains balance, generates power, and absorbs impact. For example, analyzing the gait cycle of a runner can reveal inefficiencies that may lead to injuries. By optimizing movement patterns, biomechanics contributes to improving athletic performance and developing assistive technologies such as prosthetics and orthotics.

  Social Class and Mobility -...

  Social class and mobility are central concepts in understanding how societies function and evolve. The classification of individuals into different social classes based on income, occupation, education, and wealth shapes life experiences, opportunities, and access to resources. At the same time, social mobility—the ability of individuals or groups to move within a social hierarchy—determines whether societies remain rigidly stratified or allow for upward and downward movement. These dynamics influence economic stability, political structures, and cultural identities, making the study of social class and mobility essential for comprehending broader social patterns. 
  Social class is typically divided into broad categories such as the upper class, middle class, working class, and lower class. Each class has distinct characteristics that define access to wealth, education, job opportunities, and social networks. For example, the upper class often benefits from inherited wealth and exclusive professional opportunities, while the working and lower classes may experience financial instability and limited career advancement. These disparities create divisions that influence daily life, from the quality of healthcare received to the neighborhoods people can afford to live in. 
  Social mobility refers to changes in an individual’s or family’s social position over time. Mobility can be upward, where individuals improve their socioeconomic status, or downward, where they experience a decline. It can also be intergenerational, occurring across multiple generations, or intragenerational, happening within an individual’s lifetime. Various factors influence mobility, including education, economic conditions, public policies, and structural barriers such as discrimination or unequal access to opportunities.

  Biocivilisations - A New Look at...

  Biocivilisations is an important, original rethinking of the mystery of life and its deep uncertainty, exploring the complex civilisations that existed on Earth long before humans.  
  What is life? Many scientists believe life can be reduced to ‘mechanistic’ factors, such as genes and information codes. Yet there is a growing army of scientists, philosophers and artists who reject this view. The gene metaphor is not only too simplistic but deeply misleading. If there is a way to reduce life to a single principle, that principle must acknowledge the creativity of life, turning genetic determinism on its head.  
  The term biocivilisations is the acknowledgement of this uncertainty of life, as opposed to a quasi-certainty of the human position governed by a narrow time window of the scientific revolution. Life existed without humans for more than 99.99 percent of the Earth’s existence. Life will also continue without humans long after our inevitable extinction.  
  In Biocivilisations, Dr Predrag Slijep?evi? shows how bacteria, amoebas, plants, insects, birds, whales, elephants and countless other species not only preceded human beings but demonstrate elements of how we celebrate human civilisation – complex communication, agriculture, science, art, medicine and more.  
  Humans must try to adopt this wisdom from other biocivilisations that have long preceded our own. By rethinking the current scientific paradigm, Dr Slijep?evi? makes clear that a transformation – from a naïve young species into a more mature species in tune with its surroundings – will save us from our own violence and the violence we inflict on the rest of our living planet.

  A Primer of Life Histories -...

  Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age—or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. Life-history research plays an integral role in species conservation and management. 
   
   
   
  This accessible primer encompasses the basic concepts, theories, and applied elements of life history evolution, including patterns of trait variability, underlying mechanisms of plastic/evolutionary change, and the practical utility of life-history traits as metrics of species/population recovery, sustainable exploitation, and risk of extinction. 
   
   
   
  A Primer of Life Histories is designed for listeners from a broad range of academic backgrounds and experience, including graduate students and researchers of ecology and evolutionary biology. It will also be useful to a more applied audience of academic/government researchers in fields such as wildlife biology, conservation biology, fisheries science, and the environmental sciences.

  In the vast expanse of the cosmos, there exists an enigmatic substance that eludes detection yet exerts a profound influence on the universe's structure and evolution. This substance, known as dark matter, remains one of the greatest mysteries of modern astrophysics, captivating the imaginations of scientists and enthusiasts alike. 
    
  Dark matter's existence is inferred from its gravitational effects on visible matter and light, yet its nature remains elusive. Despite decades of research and numerous experimental endeavors, the true identity of dark matter continues to evade detection, challenging our understanding of the fundamental constituents of the universe. 
    
  In parallel, another frontier of scientific exploration has emerged within the intricate ecosystems of the human body: the microbiome. Comprising trillions of microorganisms inhabiting every surface of our bodies, the microbiome plays a crucial role in human health and disease. Yet, like dark matter, much of the microbiome's complexity remains shrouded in mystery, awaiting further exploration and understanding.
