To obtain high-quality, purified nucleic acids, scientists can use several different methods, including phenol-chloroform extraction, cesium chloride/ethidium bromide (CsCl/EtBr) gradient ...
Blood RNA extraction is fundamental to modern biomedical research and clinical diagnostics, providing the basis for comprehensive gene expression profiling. This process involves isolating ...
Researchers at Stockholm University have extracted and sequenced the oldest known RNA molecules in the world (Cell 2025, DOI: 10.1016/j.cell.2025.10.025). The ancient RNA (aRNA) comes from skin and ...
Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...
We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...
It was 2012 when Love Dalén, a paleogeneticist at Stockholm University, first laid eyes upon a special specimen on a lab table in eastern Siberia. "Our Russian collaborators said, 'Come here into this ...
The body of the young woolly mammoth known as Yuka was so well-preserved that scientists were able to recover ancient RNA molecules. (Valeri Plotnikov) It was 2012 when Love Dalén, a paleogeneticist ...
