Proteins cooperate to break up energy structures in oxygen starved heart cells

Health Problems

During a heart attack, the supply of oxygen to heart cells is decreased. This reduced oxygen level, called hypoxia, causes the cell’s powerhouses, the mitochondria, to fragment, impairing cell function and leading to heart failure. Until now, few details have been known about how this process occurs. Researchers at the National Institute for Physiological Sciences, Japan, have revealed how filamin […]

Can a new colleague be trusted with confidential information? Will she be a cooperative team player on a critical upcoming project? Assessing someone’s motives or intentions, which are often hidden, is difficult, and gauging how to behave toward others involves weighing possible outcomes and personal consequences. New research published in Nature Communications indicates that individuals who are tolerant of ambiguity—a […]
