| Human behavior sabotages CO2-reducing strategies Posted: 29 Sep 2021 08:28 AM PDT To slow down climate change, societies tend to focus on two solutions for reducing greenhouse gas emissions: improving energy efficiency and developing and using renewable energy sources. A new study compared every U.S. state's CO2 emissions with their investment in the two solutions from 2009 to 2016. The authors found no statistically significant difference between energy efficiency improvement and renewable energy development -- both resulted in some reductions in CO2 emissions when considering all societal sectors, although renewable energy investment was slightly more impactful. |

Researchers discovered mice who ate high-fat diets produced less of these tags on their intestinal cells, suppressing the ability of immune cells to identify and eliminate intestinal tumors. The high-fat diet also reduced the presence of certain bacteria in the mice's gut, which normally helps maintain the production of these tags. |
