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.
Cyclana Bio, a biotechnology company pioneering tissue-level approaches to women's health, today announced the close of a £5M pre-seed funding round, co-led by NfX and Eka VC, and including Cocoa VC, Wilbe, and Angel investors.
How do mammals manage to eat in situations that cause anxiety, step into exposed spaces, or slow down when anxiety drives them to keep moving? A new study pinpoints a leptin-sensitive circuit in the lateral hypothalamus that helps to overcome anxiety to perform essential behaviors such as exploring, feeding, and limiting maladaptive hyperactivity.
Digital health tools such as apps, wearables, and web platforms can modestly improve children’s physical activity, diet, and weight outcomes. Shorter programs boost activity, while longer ones better support weight management, though effects on sleep and sedentary time remain unclear.
This systematic review and meta-analysis found that while yogurt consumption shows a modest positive association with bone health markers, its effect on bone mineral density and fracture prevention in adults is clinically negligible. Current evidence is based solely on observational studies, with low certainty and limited characterization of yogurt products.
Plastic is ubiquitous in the modern world, and it's notorious for taking a long time to completely break down in the environment - if it ever does.
The study uncovers how men's shoe designs fail women runners, urging manufacturers to create footwear that meets their specific comfort and performance needs.
A team from Huntsman Cancer Institute at the University of Utah (the U) has found that triple-negative breast cancer is fueled by lipids and that these fatty acids are a key feature of obesity that promote tumor growth.
The Influenza A virus (IAV) has been the cause of six major flu pandemics, responsible for 50 to 100 million deaths globally.
CN Bio, a leading provider of benchtop Organ-on-a-chip (OOC) solutions that accelerate drug discovery and development, today announced the launch of PhysioMimix® Core.
This study examines how sleep influences memory, revealing the interplay between emotional cues and intentional recall in memory consolidation processes.
Everywhere you go, you carry a population of microbes in your gastrointestinal tract that outnumber the human cells making up your body.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks the cells that produce insulin-a critical hormone that regulates blood sugar in the body.
In the form of a 'nasal spray', tiny gold particles act as carriers, delivering a treatment directly to the brain: developed by scientists at the Università Cattolica Rome campus/Fondazione Policlinico Universitario A. Gemelli IRCCS, a new nanotechnological device for the treatment and prevention of neuropsychiatric and neurodegenerative diseases.
Research reveals aging hearts struggle with extreme heat, increasing cardiovascular risks for older adults as climate change intensifies global temperatures.
A good night's sleep has long been understood to help us consolidate new memories, but we don't understand how. Associations with negative feelings like fear or stress can improve recall, but intentionally trying to remember can also be effective. But these two mechanisms are very different - one involuntary, one deliberate.
Research led by the University of Cambridge has found the first clear evidence that the 'good' gut bacteria Bifidobacterium breve in pregnant mothers regulates the placenta's production of hormones critical for a healthy pregnancy.
Metabolic dysfunction-associated steatotic liver disease is the most common liver disease in the world, affecting about one third of the adult population. This disorder is characterized by the accumulation of fat in liver cells, which has severe liver consequences and is also associated with a high mortality rate from cardiovascular disease.
Don't love the gym? Neither does exercise scientist Ryan Montalvo. But he goes anyway.
While any workout can seem daunting, the physical stress of exercise often affords long-term benefits. One advantage is that it triggers a physiological response that allows our cells to adjust to meet future energy demand in what's known as a hormetic response.
A new study by the University of California, Davis, shows how cells work together to avoid a sudden drop in blood sugar. Understanding these feedback loops could improve the lives of people with diabetes and help them avoid dangerous hypoglycemia.
When University of Texas at Arlington researcher Paul J. Fadel and his colleagues launched a study on vascular health in people with chronic kidney disease, they expected to better understand a long-standing belief.
