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 ...

Scientists at Children's Medical Center Research Institute at UT Southwestern (CRI) have discovered that large pieces of DNA can transfer directly between human cells, and the DNA can persist and ...

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 ...

Despite the capability of antiretroviral drugs to suppress HIV to undetectable levels, some people living with the human immunodeficiency virus can't reach the goal of viral imperceptibility even with ...

CAMBRIDGE, MA -- The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout the brain and ...
