by University of Bonn Blood vessels (red) migrate in a disorganized manner to regions with motor neurons (green). Credit: AG Ruiz de Almodovar/University of Bonn Nerve cells need a lot of energy and oxygen. They receive both through the blood. This is why nerve tissue is usually crisscrossed by a large number of blood vessels. But...

But in humans, when there is no fertilized egg, the endometrium is shed...

(March 8, 2022) – Insufficient oxygen to an area like the heart or legs, called hypoxia, is a cue to our bodies to make more blood vessels, and scientists have found some unusual partners are...
Study highlights the importance of early diagnosis and treatment WASHINGTON–Girls with anorexia nervosa can have stunted growth and may not reach their full height potential, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism. Anorexia nervosa is a condition in which a person loses an unhealthy amount of...
by NYU Langone Health The study results revolve around the long-established idea that machines within animal and human cells turn the sugars, fats, and proteins we eat into energy used by the body’s millions of cells. The molecule most used to store that energy is called adenosine triphosphate, or ATP. Along with this central role...
Understanding how stem cells interact with their surroundings could lead to better lab-grown tissues.Credit: Imperial College London Tissues grown in the lab from stem cells may fail to live up their therapeutic promise because the cells choose their own fate. For the last 20 years, scientists have worked to engineer tissues for use in a...
