12 structurally diverse bioactive coumarins were screened using semitargeted LC-MS/MS metabolomics and ex vivo cultures of human feces. The dataset, authored by Gabrielle Mingolelli and last updated in April 2026, explores how the gut microbiome reduces the α,β-unsaturated lactone of these compounds, a pathway involving 11 identified microbial species.
Metabolomics data from a screen of 12 structurally diverse bioactive coumarins using semitargeted LC-MS/MS and ex vivo cultures of human feces. The dataset was created by Gabrielle Mingolelli and last updated on 2026-04-28. It investigates a specific microbial pathway that reduces the α,β-unsaturated lactone in coumarins, a class of natural products and drug scaffolds.
12 structurally diverse bioactive coumarins were screened for metabolism by the human gut microbiome using semitargeted LC-MS/MS metabolomics and ex vivo fecal cultures. The dataset, authored by Gabrielle Mingolelli and last updated in April 2026, demonstrates a single metabolic pathway reducing the α,β-unsaturated lactone in multiple coumarins, impacting their bioactivity.
VideoMarathon is a large-scale multimodal dataset containing approximately 9,700 hours of video paired with 3.3 million question-answer pairs. It was created by GarrickAI for academic research purposes and covers 22 diverse tasks across six fundamental topics. The dataset was last updated on 2026-05-25.
Administrative agreements detail how cities and regional county municipalities in Quebec are served by 9-1-1 emergency call centers. The data layers specify service via satellite phone for areas lacking cellular coverage and via cell phone within coverage zones of Rogers and Bell networks. Information is restricted for use by the Ministry of Public Safety and 9-1-1 centers.
ACT Sensitive Species List identifies native species and ecological communities for which precise location data is withheld to prevent threats like poaching or disturbance. The dataset is produced by the ACT Government's Office of Nature Conservation and was last updated in April 2026. It is governed by the ACT Sensitive Species and Ecological Data Policy and section 363 of the Nature Conservation Act 2014.
Geoscience Australia Data provides a dataset mapping the spatial and temporal variability of coastal upwelling systems along the 4500 km southeastern coast of Australia. The data is derived from 14 years of monthly MODIS sea surface temperature (SST) observations. It identifies two persistent upwelling systems and characterizes their variability in area, SST anomaly, chlorophyll-a concentration, and speed.
224 reference sites for aquatic health monitoring were collected from 2004 to 2010. The dataset supports a Reference Condition Approach model for bioassessment based on benthic macroinvertebrates, with data analyzed at the family level. It was developed by the University of Western Ontario, Fisheries and Oceans Canada, and the Yukon Government.
Four high-resolution bathymetry grids model the seabed around Lord Howe Island, located 450km off the coast of New South Wales. The dataset integrates bathymetry with the island's topography and was created by Geoscience Australia. The report describes data collection, quality control, and gridding methodologies.
A landscape-level GIS coverage of large fires within Yukon, spanning from 1946 to the present. The dataset includes fire perimeters, originally limited to fires over 200 hectares, with more recent additions of smaller fires near communities. It is provided by the Government of Yukon.
A Fisheries Science Partnership programme collected data on sprat and sardine stocks in the South west of England through an industry-led self-sampling initiative. The 2020-21 season introduced a phone app for data collection and onboard temperature/pressure sensors to study environmental conditions. This work contributes a multi-year time series of length data used in ICES stock assessments for divisions 7de and 7.
An atlas of bird species observed in the Geelong area of Australia. The dataset includes many of the over 800 species found in Australia and its territories, searchable by common or scientific name. It is provided by the City of Greater Geelong and was last updated in April 2026.
Experimental data and analysis scripts from Y.Z. Sinzato's manuscript 'On Linear and Non-Linear Mechanics of Cyanobacterial Colonies', submitted in 2026. The 159.7 GB repository contains three datasets: bulk shear rheology, micropipette force sensing, and EPS staining images. Files include CSV data from rheometers, processed force measurements, and TIF microscopy image stacks.
The Van Diemen Rise in the Timor Sea, specifically the East Malita Graben area, is the geographic focus. This dataset describes modern geological processes and Quaternary evolution to meet environmental baseline requirements for potential petroleum exploration. It was produced by the Australian Ocean Data Network and relates to a release planned in 1992.
Beltsville Agricultural Research Center (BARC) was the target for this Airborne Multi-angle Imaging SpectroRadiometer (AirMISR) flight on July 21, 2001. The dataset contains imagery from nine distinct viewing angles (0°, ±26.1°, ±45.6°, ±60.0°, ±70.5°) across four spectral bands, collected by a single camera on a NASA ER-2 aircraft. This multi-angle, multi-spectral data is designed to support studies of Earth's ecology and climate, simulating the satellite-borne MISR instrument.
Yu-Ning Liu authored a 23.5 KB text document on figshare, last updated April 13, 2026. The document is a critical appraisal of preclinical evidence for paeoniflorin as a disease-modifying therapy for diabetic peripheral neuropathy. It reviews mechanisms of action, highlights key translational constraints like bioavailability and exposure challenges, and outlines priority next steps for research.
Biological and sediment data from a survey of Bass Strait fauna conducted by Museum Victoria between 1979 and 1983, with supplementary data from later Geoscience Australia and Australian Hydrographic Office surveys. The results indicate a particularly diverse fauna with high small-scale variation, influenced by factors like longitude and depth. Analysis suggests the biota reflect intergrading assemblages rather than discrete species associations.
Vegetation and environmental plot data document post-fire succession in Arctic Alaska tundra. The dataset contains complete species lists and cover abundance for plots in fire scars and adjacent unburned areas on the Seward Peninsula and Brooks Range foothills. Data was collected by ORNL_CLOUD during field surveys in late June and July of 2011 and 2012.
A 2005 survey recorded 7,578 birds of 37 species and sightings of five cetacean species during the Strategic Environmental Assessment SEA7 cruise CD174 in the Rockall Trough. The data was collected onboard the RSS Charles Darwin by the British Geological Survey, with the track covering the Firth of Clyde, North Channel, continental shelf, and Rockall Trough margins. Survey conditions were frequently poor due to unseasonable weather.
Forestry Grant Scheme claims data shows areas where funding was paid for establishing natural regeneration of native tree species. This dataset supports Scotland's target of creating 12,000 hectares of new woodlands annually to combat climate change and enhance biodiversity. The data is provided by the Government Digital Service and relates to the Woodland Improvement Grant for Habitats and Species.
