| Posted: 29 Sep 2021 09:43 AM PDT Mercury released into the atmosphere by industry enters the sea and from there makes its way into the food chain. Now, an analysis by the University of Basel has revealed how the harmful substance enters seawater in the first place. This is not primarily via rainfall, as previously assumed, but rather also involves gas exchange. Measures to reduce mercury emissions could therefore take effect faster than previously thought. |

| 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. |

Many of them are intoxicated or are using illicit substances, which may alter the properties of ketamine. A study explored if patients who received prehospital ketamine with concomitant substance intoxication have higher rates of subsequent intubation in the ER compared to those without confirmed substance usage. Among the results, cocaine intoxication had a statistically significant 5.75-fold increased rate of intubation. |

This throws into question the accepted mathematical model on the evolution of human speech. |
| Zeroing in on the origins of Earth’s 'single most important evolutionary innovation' Posted: 28 Sep 2021 04:38 PM PDT Scientists estimate that oxygenic photosynthesis -- the ability to turn light and water into energy, releasing oxygen -- first evolved on Earth between 3.4 and 2.9 billion years ago. |
| How high-fat diets allow cancer cells to go unnoticed Posted: 28 Sep 2021 04:38 PM PDT The immune system relies on cell surface tags to recognize cancer cells. 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. |
