Global Efforts to Reduce Infectious Diseases Must Extend Beyond Early Childhood

Global efforts to reduce infectious disease rates must have a greater focus on older children and adolescents after a shift in disease burden onto this demographic, according to a new ...

Researchers Develop Digital Test to Directly Measure HIV Viral Load

A milliliter of blood contains about 15 individual drops. For a person with human immunodeficiency virus (HIV), each drop of blood could contain anywhere from fewer than 20 copies of the virus to more than 500,000 copies. Called the viral load, this is what is measured to allow clinicians to ...

Researcher Uses Pressure to Understand RNA Dynamics

Just as space holds infinite mysteries, when we zoom in at the level of biomolecules (one trillion times smaller than a meter), there is still so much to learn. Scientists are studying the conformational landscapes of biomolecules and how they modulate cell function. When biomolecules receive ...

Researchers Use 'Natural' System to Identify Proteins Most Useful for Developing an Effective HIV Vaccine

Scientists have spent years trying to develop an effective HIV vaccine, but none have proven successful. Based on findings from a recently published study, a research team may have put science one step closer to that ...
