Researchers Enable Small-Molecule-Mediated Precision Protein Editing in Living Cells

While genome editing technologies have revolutionized biology, a key gap remains: the lack of methods for direct, site-specific single amino acid editing in endogenous proteins. The ability to directly and precisely manipulate native proteins with...

Scientists Develop Cytoplasmic ssDNA–LNP System for Longer-Lasting Antigen Expression

Lipid nanoparticles (LNPs) have become a leading delivery platform for nucleic-acid medicines, particularly messenger RNA (mRNA). Yet mRNA can be unstable in the cytoplasm, and protein expression often declines within about 24 hours. Self-amplifyi...

Researchers Design an Opioid Receptor Modulator That Strengthens Morphine Analgesia at Lower Doses

Pain, especially moderate to severe chronic pain, remains a major clinical problem. Opioid drugs are still widely used because they provide strong and fast pain relief. But their benefits come with serious costs, including respiratory depression, ...
