The Anti-CRISPR

By Meghan Bialt-DeCelie ’19   Since the explosion of CRISPR-Cas 9, a gene editing technology, researchers have been further exploring its mechanisms and ways of improving the system. AcrIIA4 is a known anti-CRISPR protein that inhibits the CRISPR-Cas 9 complex, but the mechanism and residues involved were not as explored. Researchers lead by Jiyung Shin,…

Magnetic Nanoparticles for Oil Removal

Meghan Bialt-DeCelie ’19 One of the costliest processes in oil and gas production is safe disposal of produced water. This water contains tiny amounts of oil that are difficult to separate and make water unsafe for the environment. Traditional methods such as gravitational separation of oil are costly and are not reliable for removing the…

Vanadium Dioxide Conducts Electricity, But Not Heat

By Megan Tan ‘19 Thermal and electrical conductivity need to be proportional in electrical conductive solids. Although several metals can conduct electricity better than they can conduct heat, this phenomenon has only been known to occur at extreme temperatures. However, a recent study led by Professor Junqiao Wu from the University of California, Berkeley and…

Enzyme in Soil Bacteria Inhibits Biofilm Formation

      Patrick Yang ‘20 Pseudomonas aeruginosa is a multidrug resistant bacterium responsible for serious medical illnesses, such as pneumonia, sepsis, and cystic fibrosis. The bacterium produces a metabolite called pyocyanin, which largely contributes towards the pathogen’s toxicity. A recent discovery found that pyocyanin also aids in the aggregation of bacteria to form biofilm.…
