Our ability to “read” DNA has made tremendous progress in the past few decades, but the ability to understand and alter the genetic code, that is, to “rewrite” the DNA-encoded instructions, has lagged behind.
Scientists have found a way to create rewritable digital data storage in DNA through means similar to binary coding.
Sometimes, remembering and forgetting are hard to do.

Development of a new way to make a powerful tool for altering gene sequences should greatly increase the ability of researchers to knock out or otherwise alter the expression of any gene they are studying.
Researchers from Mount Sinai School of Medicine have developed a method to derive enough DNA information from non-DNA sources—such as RNA—to clearly identify individuals whose biological data are stored in massive research repositories.
Researchers at UCLA and New York University have developed a method to detect sequence differences in individual DNA molecules by taking nanoscopic pictures of the molecules themselves.
DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...
