» How quickly do different cells in the body replace themselves? Table 1: Cell renewal rates in different tissues of the human body.
Values are rounded to one significant digit. Giving context through daily life replacement processes, we note that hair elongates at about 1 cm per month (BNID 109909) while fingernails grow at about 0.3 cm per month (BNID 109990), which is about the same speed as the continental spreading in plate tectonics that increases the distance between North America and Europe (BNID 110286). The question of cell renewal is one that all of us have intuitive daily experience with. We all notice that our hair falls out regularly, yet we don’t get bald (at least not until males reach a certain age!). Similarly, we have all had the experience of cutting ourselves only to see how new cells replaced their damaged predecessors. Figure 1. How can the replacement rates of the cells in various tissues in our body be measured? Weightlifting could improve cognition, according to new study.
Resistance exercise, such as weightlifting, benefits cognitive abilities like attention, reasoning and memory, according to a new study from the University of Alabama at Birmingham.
"This study is an important step in understanding the relationship between physical health and cognitive and mental health," said Daniel Mirman, Ph.D., associate professor in the UAB College of Arts and Sciences' Department of Psychology. "The health and physical benefits of exercise are well-established. Cancer Inc. – Dr. Jason Fung.
In the early 20thcentury, cancer didn’t attract much attention.
The biggest health problems were infectious diseases — pneumonia, gastrointestinal and tuberculosis. The American Society for the Control of Cancer (ASCC) was created in 1913 and stressed the importance of early detection and aggressive treatment. In the 1940s, they championed the routine use of the Pap smear for cervical cancer. It was hugely and stunningly successful as death rates from cervical cancer dropped quickly. This was an auspicious start. But deaths from infections would drop precipitously over the first half of the century due to improving sanitation and the momentous discovery of antibiotics. Finally, deciding that enough was enough, then President of the United States, Richard Nixon declared war on cancer in 1971.
Optimizing Protein Synthesis. Hunter-gatherer past shows our fragile bones result from physical inactivity since invention of farming. Diverse metabolic reactions activated during 58-hr fasting are revealed by non-targeted metabolomic analysis of human blood. Quantification of blood metabolites from 4 volunteers during fasting Blood samples were obtained from four young, healthy, non-obese volunteers.
Neanderthals were sprinters rather than distance runners, our study surprisingly suggests. The image of Neanderthals as brutish and culturally unsophisticated has changed in recent years – they could make cave art, jewellery, complex stone tools and may have had language and cooked foods.
Yes, they were extremely physically strong – certainly stronger than the vast majority of humans living today. And yes, they went extinct just after our own species entered their territories (albeit with a small amount of interbreeding). But neither fact means they were sluggish or cognitively inferior to us humans. In our new study, published in Quaternary Science Reviews, we now challenge another long-held view about our distant cousins: that they were pursuit hunters adapted to living in the cold tundra environments.
