Vitamin E significantly improves immune function in sea cucumbers, new study finds Sea cucumbers (Apostichopus japonicus) have been slowly disappearing from ocean floors over the last few decades, mostly due to overfishing for food and medicinal purposes. Despite their name, sea cucumbers are aquatic animals that have been shown to have a positive impact on coral in the ocean, as they reduce detrimental sediment while feeding on nearby bacteria and microalgae. To combat their decreasing natural populations, sea cucumbers are now often cultivated and farmed in a controlled commercial setting. /news/2025-08-vitamin-significantly-immune-function-sea.html Molecular & Computational biology Agriculture Tue, 12 Aug 2025 07:20:01 EDT news674133295 Deep learning advances imaging mass spectrometry with virtual histological detail An international team of researchers from the University of California, Los Angeles (UCLA), Vanderbilt University, and Delft University of Technology has developed an artificial intelligence (AI) method that virtually stains images generated through imaging mass spectrometry (IMS).
