Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.
Octopuses are not much like humans -; they are invertebrates with eight arms, and more closely related to clams and snails.
The University of Konstanz’s Plant Physiology and Biochemistry research group has discovered previously unrecognized molecular mechanisms by which plants acclimatize to their environment—vital basic knowledge in times of climate change.
Researchers investigating the fundamental brain mechanics of autism spectrum disorder have discovered that a gene mutation known to be connected with the illness causes considerably more overstimulation of brain cells than in neuronal cells without the mutation.
A dietary modification may be essential to improving colon cancer treatment, according to research from the University of Michigan Rogel Cancer Center.
University of Cologne researchers have uncovered the mechanism by which cells can get rid of mutated mitochondrial DNA (mtDNA)—the heart of each of our cells, the mitochondria.
More sociable monkeys have a higher abundance of certain beneficial gut bacteria, and a lower abundance of potentially disease-causing bacteria, new research has found.
The overuse of antibiotics has forced microorganisms to evolve defenses against this kind of treatment. Antibiotic resistance is a problem that the WHO now views as one of the major hazards to human health.
Andor Technology, an Oxford Instruments company and a world leader in scientific imaging solutions, has today announced the launch of two new scientific CMOS cameras, specifically designed for life science researchers.
Scientists at Weill Cornell Medicine have created a computational method for mapping the architecture of human tissues in extraordinary detail. Their method guarantees to expedite research on organ-scale cellular interactions and could lead to strong new diagnostic strategies for a variety of disorders.
Not just three, but even five proteins share important roles in the formation and function of synapses and can substitute for each other. This discovery was made by a team of the research focus "Mental Health & Neuroscience" of the Karl Landsteiner University of Health Sciences Krems (KL Krems) and the CavX PhD program of the Medical University of Innsbruck.
Numerous candidate genes that affect longevity have recently been found, according to research from the Interventions Testing Program, which is supported by the National Institute on Aging (NIA).
When exposed to starvation and stress, certain bacteria enter a dormant state in which life functions cease. These cells, known as spores, can resist punishing extremes of heat, pressure, and even the extreme conditions of outer space by entering a profound hibernation.
Soil antimicrobial resistance (AMR) poses significant health risks due to the possibility of transfer to humans via direct contact and the food chain.
According to a recent study, it is possible to genetically alter the lignin chemistry of plants to improve their ability to recover from drought without compromising the size of the plant or seed production.
How animals are able to interpret natural light sources to adjust their physiology and behaviour is poorly understood.
According to a recent study, brain cells with the same “birthdate” are more likely to connect into cooperative signaling circuits that perform a variety of tasks, including memory storage.
Researchers at Penn Medicine have found that when cells are impacted by the disease, the physical structure of their genome changes.
The immune system may attack the liver when fat builds up there. The chemical that triggers these responses has been discovered by Weill Cornell Medicine researchers in a recent study, and this information helps to explain the dynamics of liver damage that can accompany type 2 diabetes and obesity.
With organoids to model early growth, scientists employed a developing microscopy technology to observe that new neurons find it hard to reach their developmental goal.
Researchers have discovered a gene that enhances muscular strength when activated by physical activity, opening the door to the creation of healing therapies that mimic some of the advantages of exercise.
