The life sciences are at a critical point in the transition from "reading" the life code to "writing" the life function. At the forefront of precision medicine, CRISPR gene editing technology has evolved into the era of "base editing" and "pilot editing", which allows scientists to achieve accurate replacement of single bases without cutting off the double strand of DNA, greatly improving the safety of gene therapy and bringing dawn to the treatment of genetic diseases. At the same time, the mRNA technology platform has gone beyond vaccines and is expanding to cancer immunotherapy and protein replacement therapy. By chemically modifying nucleotides and optimizing delivery systems for lipid nanoparticles (LNPs), researchers are able to achieve targeted delivery to specific tissues, such as the liver, spleen, and even the brain, unlocking the ability to intervene against "non-druggable" targets. In the field of nutritional health, the next generation of probiotics based on the gut microbiome has become a hot spot. Scientists used multi-omics techniques to analyze the interaction mechanism between the flora and the host, to excavate strains with metabolic regulation functions such as mucinophilia Ackermania, and to develop in vivo biologics (LBPs). This dual intervention, from the molecular level to the ecological level, marks a new stage in the life and health industry that is becoming highly personalized and intelligent.
