Terahertz waves, typically known as non-ionizing radiation, have now been pushed to new limits where they can behave as ionizing radiation under specific conditions. A groundbreaking advancement by a collaborative team of scientists from Korea and the U.S. has led to the creation of the most intense terahertz pulses ever recorded. These pulses are powerful … Read more
Harnessing energy from plasma involves a precise understanding of its behavior during fusion, particularly in maintaining its heat, density, and stability. A new theoretical model focusing on a plasma’s edge, which can become unstable and bulge, brings commercial fusion power closer to realization. “The model refines the thinking on stabilizing the edge of the plasma … Read more
Both literally and figuratively, light pervades the world. It banishes darkness, conveys telecommunications signals between continents and makes visible the invisible, from faraway galaxies to the smallest bacterium. Light can also help heat the plasma within ring-shaped devices known as tokamaks as scientists worldwide strive to harness the fusion process to generate green electricity. Now, … Read more
The Monell Chemical Senses Center has long been at the forefront of research into sweet taste, tracing back to 2001 when Monell scientists were among the first to identify and describe the mammalian sweet taste receptor, TAS1R2-TAS1R3. Over the past two decades, Monell researchers have significantly advanced our understanding of the genetics and functionality of … Read more
Animal development, also known as embryonic development, encompasses the complex processes through which a single fertilized egg cell transforms into a multicellular organism with distinct tissues, organs, and body structures. This intricate journey involves cellular differentiation, tissue organization, morphogenetic movements, and regulatory mechanisms that orchestrate the formation of body axes, germ layers, organ systems, and … Read more
Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) measured a new record for a fusion device internally clad in tungsten, the element that could be the best fit for the commercial-scale machines required to make fusion a viable energy source for the world. The device sustained a hot fusion plasma … Read more
Creating heat from fusion reactions requires carefully manipulating the properties of plasma, the electrically charged fourth state of matter that makes up 99% of the visible universe. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have finished building a new plasma measurement instrument, or diagnostic, that could aid that … Read more
Immunology is the branch of biomedical science that focuses on the study of the immune system, which is the body’s intricate network of organs, tissues, cells, and molecules that work together to defend against pathogens, foreign substances, and abnormal cells. The immune system plays a vital role in maintaining health and protecting the body from … Read more
Physiology is the branch of biology that focuses on the study of the functions and processes of living organisms and their parts. It encompasses various levels of organization, from cells and tissues to organs and organ systems, and examines how these components work together to maintain homeostasis and support life. In this discussion, we’ll delve … Read more
Human anatomy, the study of the body’s structure and organization, provides a foundational framework for understanding the complex organization and functions of the human body. From the microscopic level of cells and tissues to the macroscopic level of organs and organ systems, human anatomy elucidates the anatomical structures, physiological processes, and interconnected systems that sustain … Read more
The cell, often described as the fundamental unit of life, represents the building block of all living organisms. This microscopic entity is the smallest structural and functional unit of life, capable of carrying out the essential processes necessary for an organism’s survival and reproduction. From single-celled organisms like bacteria to complex multicellular organisms like humans, … Read more
In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature of the core of the sun. Zap Energy’s unique approach, known as a sheared-flow-stabilized Z pinch, has now … Read more
The origin and evolution of the universe have fascinated humanity for millennia. Modern scientific theories, such as the Big Bang theory, provide a framework for understanding these cosmic processes.
