3D Organ printing and regenerative medicine
Introduction 3D organ printing, also known as bioprinting, is a revolutionary technology that has emerged as a powerful tool in regenerative medicine. By enabling the precise deposition of cells, biomaterials, and bioactive molecules, bioprinting allows for the creation of complex tissue constructs and functional organs. This technology addresses critical challenges in healthcare, such as organ…

Effect of audio on human cells
Studies indicate that sound, particularly music, can influence cell viability, motility, and gene expression across various cell types. This response is not limited to auditory cells; non-auditory cells also exhibit significant reactions to sound stimuli. Sound can effect on cell viability, mechanotransduction, and physiological responses, highlighting the potential therapeutic applications of these findings. Effects on…

Frequency illusion and cognitive perception
In an era of information overload, human perception is shaped by cognitive biases that filter and prioritize stimuli. One such cognitive bias is the frequency illusion, also known as the Baader-Meinhof phenomenon, which occurs when newly learned information seems to appear repeatedly in a short period. While this experience may seem like an increase in…

Why children prefer cartoons over real humans
Cartoons have been a staple of children’s entertainment for decades, captivating young minds with their colorful visuals, imaginative worlds, and exaggerated characters. While live-action films and television programs featuring real humans offer rich storytelling and relatable experiences, they often struggle to capture the same level of engagement from young audiences. The Role of Cognitive Development…

Habit reinforcement
Beyond the practical benefits of forming habits, such as improved health or productivity, there are also psychological and physiological benefits. The process of habit formation can boost self-esteem and confidence. Successfully sticking to a new habit reinforces the belief that change is possible, which can create a positive feedback loop that encourages further success. Physiologically,…

Hermaphroditism in nature
Hermaphroditism in nature is a fascinating reproductive strategy where an organism possesses both male and female reproductive organs, allowing it to produce both sperm and eggs. This phenomenon is observed across a diverse range of species, including plants, invertebrates, and some vertebrates. Hermaphroditism can be advantageous in environments where mates are scarce, enabling individuals to…

Neurological patterns in chronic criminals
In recent decades, advancements in neuroscience have offered deep insights into the neurobiological foundations of behaviour, shedding light on the possible brain-based causes of chronic criminality. The study of how certain neural characteristics predispose individuals to deviant behaviour is a growing field known as neuro-criminology. This interdisciplinary domain merges neuroscience, psychology, and criminology to explore…

Biorhythm in humans : myth or reality?
We all feel high and low with time. Sometimes we are fastest, strongest, and healthy. And at other times, we are in the opposite mood. This is biorhythm. The equations used to calculate it are given on Wikipedia. Biorhythm theory suggests that our physical, emotional, and intellectual states follow natural, cyclical patterns, which influence how…

Using microbes for durable concrete
Conventionally, organic matters in concrete were considered to be undesirable. But recent study with selected microbes has shed new light on its usefulness. Both useful and deteriorating microbes has been identified. Metabolic activity of microbes produces acid which degrade concrete. These kinds of deterioration are pronounced in location having high microbial activities such as near…
