Biomedical researchers at Texas A&M University may have discovered a way to stop or even reverse the decline of cellular energy production—a finding that could have revolutionary effects across ...

Researchers at the Francis Crick Institute and AlveoliX have developed the first human 'lung-on-chip' model using stem cells taken from only one person. These chips simulate breathing motions and lung ...

Researchers from University of California San Diego Sanford Stem Cell Institute have discovered that spaceflight accelerates the aging of human hematopoietic stem and progenitor cells (HSPCs), which ...

The immune system acts as a critical sentinel of organismal aging, integrating the sensing of physiological states with the execution of defense and clearance functions. Immunosenescence not only ...

If scientists could shrink themselves to microscopic size and take a journey through the human body—like the submarine crew in the 1966 science fiction classic "Fantastic Voyage"—one of their first ...
