Single Neurons Require Sleep To Perform Nuclear Maintenance

Researchers at Bar-Ilan University in Israel report a novel and unexpected function of sleep that they believe could explain how sleep and sleep disturbances affect brain performance, aging and various brain disorders. Using 3-D time-lapse imaging techniques in live zebrafish, the researchers were able to define sleep in single-chromosome resolution, and show for the first […]

DNA Sequencing Is Inadvertantly Exacerbating Social Biases And Inequalities

At the cutting edge of modern science, DNA sequencing promises to transform many aspects of human life. It’s already playing a significant role in law enforcement, as well as medical and historical research. But there’s a growing inequality in its impacts and in the chances of your genetic data being recorded – whether that’s by […]

Protein Level DNA Barcoding Identifies Key Cancer Immunity Genes

A new technology for simultaneously analyzing the functions of hundreds of genes with resolution reaching the single cell level has been developed by scientists at Mount Sinai Hospital. The method relies on a barcoding approach using a novel protein. Since the sequencing of the first human genome in the early 2000s revealed a set of […]

How DNA-based Dendrimers Transport Nanoparticles

Short segments of DNA molecules are perfect candidates for the controllable design of novel complex structures. Physicists from the University of Vienna, the Technical University of Vienna, the Jülich Research Center in Germany and Cornell University in the U.S.A., investigated methodologies to synthesize DNA-based dendrimers in the lab and to predict their behavior using detailed […]
