Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

UVA researchers discover key to HIV latency and reactivation

University of Virginia School of Medicine scientists have uncovered a key reason why HIV remains so difficult to cure: Their research shows that small changes in the virus affect how quickly or slowly it replicates, and how easily or stubbornly it can reawaken from hiding.

New injection therapy can lead to long lasting blood pressure reduction

Results from a clinical trial led by researchers from Queen Mary University of London, published today in JAMA, show that giving people with high blood pressure an injection every six months can lead to a meaningful, sustained reduction in their blood pressure.

Scientists reveal how RNA could have replicated on early earth

Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth – a key process in the origin of life.

Oral 8-aminoguanine protects aging eyes and preserves vision in preclinical study

Oral 8-aminoguanine (8-AG) treatment preserved retinal structure and rod function in aged Fischer 344 rats, significantly reducing oxidative stress and inflammation. These findings highlight the promise of 8-AG as a non-invasive intervention to slow age-related retinal degeneration.

Experts explain how H5 avian influenza adapts to infect more animals

The Gs/Gd lineage of highly pathogenic H5 avian influenza viruses—including H5N1—has rapidly evolved, spreading globally and infecting a growing range of birds, mammals, and occasionally humans. This review highlights the expanding risks, the challenges of cross-species transmission, and urgent needs for surveillance, vaccination, and a unified One Health response.

Study reveals how PAX3 protein drives melanoma growth

PAX3 is a transcription factor (proteins involved in converting DNA into RNA) that drives melanoma progression by promoting cell growth, migration and survival, while inhibiting cellular terminal differentiation, which is the final stage where a cell becomes specialized and cell division ends.
