Study uncovers the secret of long-lived stem cells
Nothing lives forever, but compared to other cells in the body, hematopoietic stem cells (HSCs) are remarkably long-lived. HSCs are blood-forming cells—they give rise to rapidly dividing progenitor cells, which in turn generate hundreds of billions.....»»
Researchers suggest that mechanical pressure triggers a key event in HIV infection
It has been more than 40 years since the beginning of the HIV/AIDS epidemic and scientists still don't fully understand how HIV enters and replicates in human cells, which has hindered the development of treatments......»»
Genetic adaptations have impacted the blood compositions of two populations from Papua New Guinea, finds study
Papua New Guinea (PNG) has a wide range of environments, each presenting unique challenges to human survival. Highlanders and lowlanders of PNG are striking examples of populations facing distinct environmental stress. Whereas the highlanders encount.....»»
Aggressive wall lizard provides clues to understanding evolution
Body shape, color and behavior often evolve together as species adapt to their environment. Researchers from Lund University in Sweden have studied this phenomenon in a specific type of large, bright green and aggressive common wall lizard found near.....»»
Scientists" research on RNA editing illuminates possible lifesaving treatments for genetic diseases
