Why some people are more prone to negative emotions than others

Why are some people particularly prone to anxiety, worry or stress, while others remain more composed? An international study led by the Central Institute of Mental Health (CIMH) shows that the amygdala—previously considered central to these processes—apparently does not explain

How fatigue shapes World Cup interceptions

An interception can last less than a second. A defender reads a pass, steps into its path and reaches the ball before its intended recipient. Yet that brief movement requires the brain to judge speed, distance and direction while the body accelerates, changes course and maintains

How an emerging class of tick-borne viruses escape human immune defenses

Warmer temperatures bring out ticks that spread diseases such as Lyme disease and Rocky Mountain spotted fever. But another class of emerging tick-borne pathogens—nairoviruses—is on the rise. Some nairoviruses cause high fevers and reduce organ function in people exposed to certa

Herpes immune response linked to Alzheimer's disease

New research has demonstrated a mechanistic link between the immune response to herpesviruses—the family of viruses related to cold sores, childhood infections and mononucleosis—and an increased risk of Alzheimer's disease. A team of scientists from Cardiff University's School of

Child maltreatment and mental health problems in children and adolescents

In children and adolescents who have experienced child abuse, the body appears to remain in a state of alert for too long, and this can affect several bodily systems, such as the neuroendocrine, immune and metabolic systems. When this alert response is prolonged, it leads to cumu

Immune response to otherwise harmless yeast becomes a problem in Crohn's disease

Almost everyone carries Candida albicans. The yeast colonizes human mucous membranes—for example, the oral mucosa and the intestine—usually silently, without causing any problems. The immune system learns early on how to deal with it. It develops specialized immune cells known as

Preclinical study points to a promising combined strategy for slowing the progression of t

An international research group led by researchers from VUB-UZ Brussels and KU Leuven has demonstrated that a combined approach targeting both the immune system and insulin-producing beta cells can slow the progression of type 1 diabetes more effectively than individual treatment

Sound waves guide cultured cells to form vessel-like networks within one week

With the aid of physical forces—in this case, sound—it is possible to actively steer the formation of engineered tissue. For example, sound waves can be used to create functional vascular networks with blood vessel-like structures in vitro. Scientists at the Center for Molecular
