A radar system developed at the University of Waterloo can wirelessly monitor the vital signs of patients; but eliminating the need to hook them up to any machines. Housed in a device smaller than a cellphone, the new technology records heart and breathing rates using sensitive radar waves; but that are analyzing by sophisticated algorithms…
Preschoolers who watch TV sleep significantly less than those who do not: according to new research by University of Massachusetts Amherst neuroscientist Rebecca Spencer and developmental science graduate student Abigail Helm. More surprising to Spencer; known for her groundbreaking research into the role of naps in children’s memory and learning, 36 % of 3- to…
Obstructive sleep apnea (OSA) is a themost common type of sleep-disordered breathing and is by cyclical alterations between pharyngeal collapse and arousals during sleep. Consequently, there are recurrent episodes of nocturnal hypoxemia; hypercapnia, endothelial dysfunction, hypercoagulability, and sympathetic overactivity. According to a new study published in The Journal of the American Medical Association (JAMA); patients who…
Stress not only harms your well-being but it also can prevent you from getting a reasonable amount of sleep. A Baylor College of Medicine sleep expert explains how stress can interfere with your nighttime schedule and ways you can sleep more when life becomes busy. “Stress can affect sleep in different ways,” said Dr. Annise…
The human body has powerful healing abilities. But treating brain disorders is no easy task, as brain cells neurons have limited ability to regenerate. Nonetheless, stem cells are a form of natural backup; a vestige of our days as still-developing embryos. The difficulty is that with age; neural stem cells ‘fall asleep’ and become harder…
Some risk factors for osteoporosis such as being older and female or having a family history of the condition; cannot avoid. But others can, like smoking cigarettes, consuming alcohol, taking certain medications; or exposed to environmental pollutants. But until now researchers have not gained a firm picture of how these exposures link up with the…
The relations among intelligence, health, and aging have well established by Deary and his colleagues (2010). One of the most comprehensive demonstrations of these relations is based on more than 70,000 people who followed from childhood to the age of 79 years. The key finding was that each 1-standard-deviation increase in intelligence at age 11…
Chronic short sleep is with increased risk of arteries, heart disease, and thus increased morbidity and mortality. New research in Experimental Physiology may have figured out why lack of sleep increases susceptibility; to heart disease and allowing doctors to identify the patients who might need to change their habits before they develop the disease. In…
Smoking has long been the biggest cause of cancer in the United States, but obesity; now the second leading cause, has gained ground. A new study from researchers at the University of Chicago finds that women with breast cancer; the most common cancer among women are at even higher risk from obesity. Breast cancers occur…
Have you had a less-than-stellar performance review lately? Do you daydream, or are you making bad decisions? It might not be about your job but about your sleep. And it’s not all your fault. They each study different aspects of health and aging. A recent study they conducted found that poor sleep may inhibit judgment and lead…
The mitochondrion (plural mitochondria) is a double-membrane-bound organelle in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack them (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads; have also reduced or transformed their mitochondria into other structures. A study at The University of…
The recurrent vibrations caused by snoring can lead to injuries in the upper airways of people who snore heavily. This, in turn, can cause swallowing dysfunction and render individuals more vulnerable to developing severe condition obstructive sleep apnea. Their ongoing research focuses on the processes behind vibratory damage and healing of the upper airway tract.…
