The association between marijuana use and the risk of developing different kinds of cancer remained largely unclear in this analysis of 25 studies. The available studies were limited by small numbers of participants with high levels of marijuana use, poor quantification of marijuana use, and the presence of other factors such as cigarette smoking, which could influence results. Long-term studies are needed to improve understanding of marijuana’s association with the risk of developing cancer.
With the increasing rate of multi-drug resistance, it is fundamental to identify new antibiotics. In this study, researchers found the synthesis of the vitamin biotin is integral for the growth of drug-resistant bacteria in human plasma. They were able to treat drug-resistant infections by inhibiting biotin synthesis in an infection mimicking human conditions. By inhibiting biotin synthesis, they have the potential to produce a novel class of antibiotics.
