| New research shows what it takes to make society change for the better Posted: 01 Apr 2022 01:05 PM PDT New research suggests that social change may depend on the relationship between beneficial behaviors and policies. Using an innovative mathematical model, researchers studied a behavior that benefits groups, but does not spread without policy support, such as a costly measure to mitigate the effects of climate change. The results showed that both behavioral change and policy change are required to achieve large-scale social change, but policy change is especially critical. |
| 'Flash droughts' coming on faster, global study shows Posted: 01 Apr 2022 01:05 PM PDT Just like flash floods, flash droughts come on fast -- drying out soil in a matter of days to weeks. These events can wipe out crops and cause huge economic losses. And according to scientists, the speed at which they dry out the landscape has increased. |
| Monkeys routinely consume fruit containing alcohol, shedding light on our own taste for booze Posted: 01 Apr 2022 11:13 AM PDT Scientists analyzed the ethanol content of fruit eaten by spider monkeys in Panama, and found that the fruit regularly contained alcohol: between 1% and 2%. The researchers also collected urine samples, most of which contained secondary metabolites of ethanol. The results provide further evidence that our primate ancestors preferentially sought out fermented, alcohol-containing fruit likely for its greater nutritional value, and that humans may have inherited this proclivity for ethanol. |
| New polymer membrane tech improves efficiency of CO2 capture Posted: 01 Apr 2022 09:21 AM PDT Researchers have developed a new membrane technology that allows for more efficient removal of carbon dioxide (CO2) from mixed gases, such as emissions from power plants. |
| Posted: 01 Apr 2022 06:48 AM PDT Researchers have discovered that key parts of the global carbon cycle used to track movement of carbon dioxide in the environment are not correct, which could significantly alter conventional carbon cycle models. This finding has the potential to change predictions for climate change, though it is unclear at this juncture if the mismatch will result in more or less carbon dioxide being accounted for in the environment. |
| Crowdsourcing campaign identifies drivers of tropical forest loss Posted: 01 Apr 2022 06:48 AM PDT To combat forest loss in the tropics, a new study uses crowdsourcing to identify the drivers of deforestation. The resulting dataset can be used to create high-resolution maps and help policymakers apply the best protection measures. |
| Scientists can predict carbon transfer in the ocean based on deep-diving tiny organisms Posted: 31 Mar 2022 02:08 PM PDT Biologists find that the health and size of ocean bacteria that eat the carbon-carrying particles can affect the speed with which they sink toward the deep ocean. They then developed a predictive model for oceanic carbon transfer. |
