Researchers discover first enzymes to catalyze a classic organic reaction

Credit: University of California, Los Angeles The Tang, Garg, and Houk research groups have discovered nature's natural protein catalysts (enzymes) that catalyze the Alder-ene reaction. All groups are part of the UCLA Department of Chemistry ....

Zebrafish embryos help prove what happens to nanoparticles in the blood

Fluorescently labelled 70 nm SiO2 nanoparticles were injected into the bloodstream of 3 days old transgenic zebrafish embryos and live-imaged at 3 min after the injection. The insets show schematics for the two conditions tested: ....
