Rare Great White shark filmed in Mediterranean Sea between Tunisia and Sicily
A volunteer diver captured rare footage of a Great White shark in the Mediterranean Sea in May while working to document ghost fishing nets. The sighting is significant because Great Whites are thought to be near extinction in the Mediterranean due to overfishing. Conservationists hope the discovery will prompt governments to establish marine protected areas in the region.
Derk Remmers, a volunteer diver working for the NGO Healthy Seas, filmed an adult male Great White shark in the Mediterranean Sea in May during a dive operation focused on documenting ghost fishing nets. The shark was spotted many miles offshore between Tunisia and Sicily. Scientists emphasize there is no cause for public concern given the shark's remote location. Overfishing is believed to have driven Great Whites to near extinction in Mediterranean waters. Conservationists view the sighting as a potential catalyst for governments to establish marine protected areas in the region to help protect the species.

Researchers Identify D-Retro-Inverso Peptide Candidates for Treating Cardiac Amyloidosis
Researchers have designed and computationally evaluated four peptide candidates made from D-amino acids that may inhibit the formation of Serum Amyloid A (SAA) fibrils associated with cardiac complications following heart attacks. The study builds on mouse model evidence suggesting SAA aggregates contribute to long-term myocardial infarction complications and may operate similarly in humans. Two candidates, DRI-R5S and DRI-H6A, were identified as particularly promising for potential drug development.
Study Identifies D-Retro-Inverso Peptides as Potential Treatments for Cardiac Amyloidosis
Researchers designed four peptide candidates using D-amino acids to inhibit Serum Amyloid A (SAA) fibril formation, which may contribute to complications following heart attacks. The study, conducted using molecular dynamics simulations in a mouse model, identified two peptides—DRI-R5S and DRI-H6A—as promising drug candidates. This work could lead to new therapeutic approaches for cardiac amyloidosis, a serious post-infarction complication.
Scientists Discover Previously Unknown Branch of Tryptophan Metabolism in Humans
Researchers identified a new enzymatic step in human tryptophan catabolism, showing that the protein ASPDH acts as a 2-aminomuconate reductase to produce a previously unknown amino acid. This discovery fills a gap in the kynurenine pathway, one of the body's major metabolic routes for processing the amino acid tryptophan. The finding expands understanding of human metabolism and may have implications for understanding NAD cofactor production and related metabolic diseases.
