Study: Fishing Bycatch Does Not Lure Lesser Black-Backed Gulls Into Offshore Wind Farms
A study of lesser black-backed gulls from a Dutch island colony found that the birds avoid an offshore wind farm, contrary to researchers' initial hypothesis that fishing bycatch would attract them into the area. The research, led by NIOZ ecologist Rosemarie Kentie, examined gull behavior on weekends when fishing activity is minimal. The findings suggest that factors other than food availability may drive gull avoidance of wind farms, which has implications for understanding wildlife interactions with renewable energy infrastructure.
Researchers studying lesser black-backed gulls from a colony on Neeltje Jans, a Dutch island, investigated whether the birds were attracted to an offshore wind farm by fishing bycatch discarded from nearby boats. The team hypothesized that food availability from fishing operations would draw gulls into the wind farm area. However, their analysis revealed that gulls rarely visited the wind farm even on weekends when fishing activity is substantially reduced, contradicting the initial assumption. The findings suggest that gull avoidance of the wind farm is driven by factors independent of food sources from fishing bycatch. This research contributes to understanding how seabirds interact with offshore renewable energy installations and may inform future wind farm siting and management decisions.
Limitations & open questions
The study's specific methodology (sample size, observation period, statistical methods), the mechanisms underlying gull avoidance of the wind farm, and whether findings apply to other gull species or populations are not detailed in the provided excerpt.

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.
Japanese researchers find Adelie penguins use group behavior to locate new foraging grounds
A Japanese research team discovered that Adelie penguins in Antarctica follow colony members to find new feeding areas after unsuccessful foraging attempts. The study analyzed data from 116 penguins fitted with activity recorders in Lutzow-Holm Bay and was published in Proceedings of the Royal Society B. The findings demonstrate how group living provides foraging advantages and may help explain the evolution of social behavior in animals.
