Could zinc be involved in forming kidney stones?

Zinc is a micronutrient that is essential for normal protein production and for various enzymes to function properly in the body. Levels are important to regulate because too much can be toxic to the kidneys whereas too little can lead to problems with immune and metabolic function as well as infertility. In a new study published in American Journal of Physiology – Renal Physiology, researchers were interested in how zinc […]

Study examines link between sleep apnea and cancer

A recent review published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology explored the link between sleep apnea and cancer (4). More and more people are living with sleep apnea. In fact, current estimates indicate that up to 24% of men as well as up to 5% of women have obstructive sleep apnea (4). Individuals with sleep apnea experience repeated cycles of low oxygen (hypoxia) and reoxygenation throughout […]

Their results, published last month in the Journal of Experimental Biology, were rather surprising: dogs showed preference towards foods high in fats (41% fat, 36% carbohydrates) whereas cats preferred foods high in carbohydrates (43% carbohydrates, 30% proteins). […]

Turns out, we really do live in our own bubbles and we have special neurons, called peripersonal neurons, that are responsible for sensing that space and sending feedback to our brains. It is thought that these neurons are important for sensing approaching dangers […]

Intelligence: Dogs vs Cats

A new study seems to have provided an answer to the age-old question of who is smarter: dogs or cats? The speculation before the study was conducted was that hunting may require extra brain cells (neurons). If true, that would mean that cats would have more neurons than dogs. My apologies to all of the cat lovers out there. The findings from the study suggest that dogs may actually be […]

Do negative facial expressions impact dogs?

As a dog owner, it seems to me as if my canine pal understands when I am happy or mad. But, is that seeming awareness due to my facial expressions or the tone of my voice? In a new study published in Behavioural Processes, researchers at the University of Lincoln and University of Sao Paulo attempted to unravel this mystery of how angry or happy human facial expressions might make […]
