+ science of New England stone walls; science as a human right US Edition - Today's top story: COP28: 7 food and agriculture innovations needed to protect the climate and feed a rapidly growing world [View in browser]( US Edition | 6 December 2023 [The Conversation]
[The Conversation]( One of the outcomes of the ongoing COP28 climate conference is a declaration, signed by more than 130 countries, to tackle planet-warming emissions from food production. University of Notre Dame agricultural economist Paul Winters details a few priority practices that could [help farmers continue to feed the world and slow emissions](, including better use of technology for weather forecasting, microbial fertilizers and reducing methane emissions from livestock. He notes that underinvestment from the commercial sector has held these and other innovations back, and he points to the importance of âpublic and philanthropic investment.â The idea of using electricity to trigger seizures in the brain to treat depression may seem kind of scary. But University of San Diego neuroscientist Sydney E. Smith argues that the method should be less stigmatized, and her recent study provides insight into why it can be effective. In a study, Smith and her colleagues probed the mechanism behind electroconvulsive therapy, or ECT, to better understand how it operates on brain waves. The experiment indicates that ECT may work by [resetting the brainâs âelectrical background noiseâ]( and restoring the function of inhibitory neurons, which play a key role in responding to stress. As someone who lives in New England and spends time on hiking trails, I often encounter stone walls. To University of Connecticut geologist Robert M. Thorson, stone walls are a lot more than just attractive scenery. With colleagues, he is working to [develop a formal interdisciplinary science of stone walls]( to help researchers understand and preserve their ecological and historical value.

[How electroconvulsive therapy heals the brain â new insights into ECT, a stigmatized yet highly effective treatment for depression]( Sydney E. Smith, University of California, San Diego Electroconvulsive therapy often evokes inaccurate images of seizing bodies and smoking ears. Better understanding of how it reduces depression symptoms can illuminate new ways to treat mental illness.
