Researchers at the Hong Kong University of Science and Technology (HKUST) developed a novel technology which allows genomic DNA and RNA sequencing to be carried out simultaneously in single cells of both frozen and fresh tissues, and identified rare brain tumor cell "spies" disguised as normal cells with this method. This breakthrough facilitates cancer research for some of the most complex and rare tumors, opening new directions for drug target discovery in the future.

The study of microRNAs (miRNAs), small RNAs that play important roles in gene regulation in animals and humans alike, have long been a topic of interest to many. How these miRNAs control and regulate gene expression, a subject of great importance in biology and medicine, is often believed to hold the keys to providing effective cures, or strategies, to different phenomenon and symptoms, such as cancer, a result of cell mutations.
