Discovery provides a more precise picture of the retina's optical properties

Researchers at the National Eye Institute (NEI) have discovered that power-producing organelles in the eye's photoreceptor cells, called mitochondria, function as microlenses that help channel light to these cells' outer segments where it's converted into nerve signals.

New radio-labeled molecule may allow a non-invasive approach to monitor inflammation in real time

Researchers at The University of Texas MD Anderson Cancer Center have developed a new radio-labeled molecule capable of selectively reacting with certain high-energy radicals that are characteristic of innate immune activity, which may allow a non-invasive approach to monitor inflammation in real time by positron emission tomography (PET) imaging.

Researchers unravel essential final steps in the production of mRNA

Proteins need to interact in a complex manner for a so-called "messenger RNA" (mRNA) to be created in human cells from a precursor molecule. mRNA provides a blueprint for proteins; the first vaccines against the coronavirus are also based on mRNAs.

Scientists reveal how droplets of transcription factors collectively read DNA regions to switch on genes

Life starts with one cell. When an organism develops, dividing cells specialize to form the variety of tissues and organs that build up the adult body, while keeping the same genetic material – contained in our DNA.

Wistar researchers takes a promising step in the direction of developing HIV vaccine

Nearly four decades after its discovery, HIV has killed 36.3 million people, with no vaccine in sight. However, a new study by researchers at The Wistar Institute, an international biomedical research leader in cancer, immunology, infectious disease, and vaccine development, takes a promising step in the direction of developing an HIV vaccine.
