Stanford University researchers have developed a computational method for identifying where cells are situated in a sample when capturing spatial transcriptomics. The method combines data from spatial transcriptions and a ...
A commonly used scientific method to analyze a tiny amount of DNA in early human embryos fails to accurately reflect gene edits, according to new research led by scientists at Oregon Health & Science University.
