Beery was drawn to the Institute\u2019s commitment to \u201ccomputing for the planet,\u201d and set out to bring her methods to global-scale environmental and biodiversity monitoring.\n\nIn the Pacific Northwest, salmon have a disproportionate impact on the health of their ecosystems, and their complex reproductive needs have attracted Beery\u2019s attention. Each year, millions of salmon embark on a migration to spawn. Their journey begins in freshwater stream beds where the eggs hatch. Young salmon fry (newly hatched salmon) make their way to the ocean, where they spend several years maturing to adulthood. As adults, the salmon return to the streams where they were born in order to spawn, ensuring the continuation of their species by depositing their eggs in the gravel of the stream beds. Both male and female salmon die shortly after supplying the river habitat with the next generation of salmon."}, {"id": "7d8e29db-4a4b-47c5-8c93-fda1e72137a7", "name": "text", "type": "string", "value": "MIT's AI Pioneer Tackles Salmon Conservation Professor Sara Beery, a rising star in MIT's Department of Electrical Engineering and Computer Science, is revolutionizing ecological conservation through cutting-edge technology. Specializing in computer vision, machine learning, and data science, Beery has set her sights on addressing real-world sustainability challenges. Her current focus? The vital salmon populations of the Pacific Northwest. These fish play a crucial role in their ecosystems, with their complex life cycle spanning from freshwater streams to the open ocean and back again. Beery's innovative approach uses AI to monitor salmon migration patterns, providing unprecedented insights into their behavior and habitat needs. Beery's work has led to the development of underwater AI cameras that can distinguish between different salmon species with 99.9% accuracy. Her team has also created a revolutionary \"salmon translator\" that can predict spawning locations based on fish vocalizations. As climate change threatens these delicate ecosystems, Beery's research offers hope for more effective conservation strategies. By harnessing the power of technology, she's not just studying nature \u2013 she's actively working to preserve it for future generations."}]}}, "typeVersion": 3.4, "notes": "This set node performs automated tasks as part of the workflow."}, {"id": "25849b47-1550-464c-9e70-e787712e5765", "name": "Merge", "type": "n8n-nodes-base.merge", "position": [1120, -160], "parameters": {"mode": "combine", "options": {}, "combineBy": "combineByPosition"}, "typeVersion": 3, "notes": "This merge node performs automated tasks as part of the workflow."}, {"id": "eaea7ef4-a5d5-42b8-b262-e9a4bd6b7281", "name": "Filter", "type": "n8n-nodes-base.filter", "position": [1340, -160], "parameters": {"options": {}, "conditions": {"options": {"version": 2, "leftValue": "", "caseSensitive": true, "typeValidation": "strict"}, "combinator": "and", "conditions": [{"id": "20a4ffd6-0dd0-44f9-97bc-7d891f689f4d", "operator": {"name": "filter.operator.equals", "type": "string", "operation": "equals"}, "leftValue": "={{ $json.text }}", "rightValue": "No"}]}}, "typeVersion": 2.2, "notes": "This filter node performs automated tasks as part of the workflow."}, {"id": "9f074bdb-b1a6-4c36-be1c-203f78092657", "name": "When Executed by Another Workflow", "type": "n8n-nodes-base.executeWorkflowTrigger", "position": [-760, -200], "parameters": {"workflowInputs": {"values": [{"name": "facts"}, {"name": "text"}]}}, "typeVersion": 1.1, "notes": "This executeWorkflowTrigger node performs automated tasks as part of the workflow."}, {"id": "0a08ac40-b497-4f6e-ac2c-2213a00d63f2", "name": "Aggregate", "type": "n8n-nodes-base.aggregate", "position": [1560, -160], "parameters": {"options": {}, "aggregate": "aggregateAllItemData"}, "typeVersion": 1, "notes": "This aggregate node performs automated tasks as part of the workflow."}, {"id": "b0d79886-01fc-43c7-88fe-a7a5b8b56b35", "name": "Merge1", "type": "n8n-nodes-base.merge", "position": [80, -180], "parameters": {"mode": "combine", "options": {}, "combineBy": "combineByPosition"}, "typeVersion": 3, "notes": "This merge node performs automated tasks as part of the workflow."}, {"id": "82640408-9db4-4a12-9136-1a22985b609b", "name": "Basic LLM Chain", "type": "n8n-nodes-base.noOp", "position": [1780, -160], "parameters": {"text": "={{ $json.data }}", "messages": {"messageValues": [{"message": "You are a fact-checking assistant.
