A drop in one fatty molecule may explain why the body’s cells slow with age
Cells throughout the human body become less efficient with age, and a newly published study points to a specific lipid, ...
Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...
Why do immune cells that are supposed to eliminate viruses suddenly turn against our own body? There are instances where killer T cells—which are meant to precisely remove virus-infected ...
A human female is born with all the egg cells she will ever have. The possibility for the development of new oocytes is zero. Given this constraint, it is crucial that these gametes remain healthy and ...
The human immunodeficiency virus (HIV), which is the cause of AIDS, is a master of deception, using just nine genes to hijack the complex cellular machinery of the human body. Yet, even after decades ...
Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants. A study by UT ...
Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...
Typically, bone marrow research relies heavily on animal models and oversimplified cell cultures in the laboratory. Now, researchers from the Department of Biomedicine at the University of Basel and ...
The human brain contains roughly 86 billion neurons, and for decades scientists have assumed that these cells are the primary ...
