Data and scripts from: Intercropping and cover cropping differentially alter maize secondary metabolism and affect herbivore resistance
No full textPlease cite as: Juan Pablo Jordán, Andre Kessler. (2026) Data and scripts from: Intercropping and cover cropping differentially alter maize secondary metabolism and affect herbivore resistance. [dataset] Cornell University Library eCommons Repository. https://doi.org/10.7298/zrbh-z633These files contain data and scripts supporting all results reported in Jordán & Kessler, Journal of Applied Ecology, Intercropping and cover cropping differentially alter maize secondary metabolism and affect herbivore resistance, 2025. In Jordán & Kessler, 2025 we found that the non-volatile secondary metabolite profiles of maize leaves and roots differed across inter and cover cropping systems, while volatile organic compound emissions remained largely unchanged. Defense-related compounds such as benzoxazinoids were generally upregulated under intercropping, while the companion plant identity further shaped the maize defense profile with bean-intercropping specifically upregulating benzoxazinoid compounds. Resistance bioassays with the generalist herbivore Spodoptera frugiperda revealed that intercropping significantly reduces leaf damage relative to cover cropping. Among the intercrops, beans increase larval mortality while alfalfa decreases larval mortality on maize plants.The study was supported by a Multistate Federal Capacity Fund from NIFA/USDA and a Sustainable Biodiversity grant from the Atkinsons Center for Sustainability, Cornell University
Data and scripts from: Modeling the Seasonality of Wind-Driven Hydrocarbon Waves in Titan's Polar Lakes

(2026) Data and scripts from Modeling the Seasonality of Wind-Driven Hydrocarbon Waves in Titan's Polar Lakes. [dataset] Cornell University Library eCommons Repository. https://doi.org/10.7298/pz39-p920These files contain data supporting all results reported in Detelich et al. "Modeling the Seasonality of Wind-Driven Hydrocarbon Waves in Titan's Polar Lakes". In Detelich et al., we found: Titan, the only body in the solar system aside from Earth with standing liquids on its surface, has polar hydrocarbon lakes and seas. As Titan's atmosphere generates light winds, there should be waves on the surface of these lakes and seas, yet, direct wave observations are unusually scant. We introduce and use PlanetWaves, an open source 4D spectral wave model, to study Titan’s waves and create seasonal maps of wave shape and propagation on Ontario Lacus and Ligeia Mare. Titan’s modeled waves grow up to 30 times larger than terrestrial waves for the same wind speed, are seasonally present and are largest in the spring and summer when winds are strongest. Average daily winds almost never exceed the wave generation threshold of 0.5 - 0.7 m/s. Average storm winds (~1.5 m/s) generate waves 15 - 48 cm in height with a period ranging 6 - 10.5 s while maximum storm winds (~4 m/s) generate waves 2.7 - 3.2 m in height with a period up to 32 s. Titan’s waves become fetch-independent at ~40 km for average storm winds occurring ~1% of a Titan year and ~100 kilometers for maximum storm winds occurring 2-3 times per Titan decade. On Ontario Lacus, storm winds blow nearly parallel to the eastern shore, potentially driving wave modification of the smooth eastern shoreline. On Ligeia Mare, waves rarely propagate toward a hypothesized wave modified shoreline suggesting that another process, such as tectonics, may contribute to a straight shoreline morphology.This material is based upon work supported by the Future Investigators in NASA Earth and Space Science and Technology (FINESST) SMD’s Graduate Student Research Fellowship under grant #171064 (C.E.D.), the National Science Foundation (NSF) Graduate Research Fellowship (GRFP) under grant #214106 (U.G.S.), and the NASA Cassini Data Analysis Program under grant 80NSSC20K0484 (U.G.S., R.V.P., A.G.H., and J.T.P.).

Safer Knives - Reducing Knife Harm
No full textOn 20th November 2025, the Safer Knives Group held a conference entitled Reducing Knife Harm. The conference was generously supported by the Economic and Social Research Council, Leeds Social Sciences Institute and hosted by the Royal College of Psychiatrists.
The objects of the Reducing Knife Harm conference were:
• Policy Development. To encourage and inform policy on the wider adoption of safer knife designs.
• Publicity. To raise the public and media profile of the importance of safer knife design.
• Government Engagement. To engage with Ministers and officials to influence legislative and regulatory direction.
• Stakeholder Outreach. To influence a wide stakeholder group including knife manufacturers, retailers, academics, and the public sector.
The conference was attended by 120 people, comprising a diverse mix of professionals, front-line experts and people with lived experience. The presentations and plenary contributions encompassed a wide range of knowledge and opinion. This book is an edited version of all those contributions.
Everyone involved hoped that the conference would act as a springboard for further change to reduce knife harm. We, all members of the Safer Knives Group, hope that this book will further that aim.

Climate literacy and labour agency in vocational education and training
No full textHow far can climate literacy be embedded into the construction vocational education and training (VET) systems? This is investigated in North America (US and Canada) and six European countries (Belgium, Denmark, Germany, Ireland, Sweden and the UK). Climate literacy entails understanding the impact of climate change on society, the sector and its different occupations. Achieving zero carbon building (ZCB) is shown to involve respecting construction workers’ embodied knowledge and experience, and empowering them to make informed decisions regarding their actions through climate-literate VET programmes, thus enhancing labour agency. Drawing on research for Canada’s Building Trade Unions’ programme Building It Green, involving interviews and analysis of case study VET systems in eight countries, this article defines climate literacy and adapts a transparency tool to map and evaluate the range of knowledge, know-how and competences required for climate-literate construction workers. The findings reveal wide variations between case studies in coordinated and liberal market economies in the incorporation of climate literacy and obstructions to this, reflecting conflicts between approaches minimising workers’ discretion and those facilitating building workers acquiring abilities and agency to make informed decisions. Understanding the value of achieving socially beneficial climate outcomes can add meaning and purpose to construction work

Data from: Fully Contained Laboratory Earthquakes: The Effect of Asperity Aspect Ratio and Free Surfaces
No full textThese files contain data supporting all results reported in Cebry et al. We found: Corner frequency (fc) and seismic moment (M0) are key parameters derived from seismic signals that are used to characterize
earthquake stress drop, rupture area, and slip. These parameters are also affected by fault geometry and boundary conditions. However, the systematic study of these effects in laboratory settings has been
challenging. This study presents laboratory earthquake experiments that examine how rupture dynamics are influenced by (1) the aspect ratio of rectangular PMMA velocity-weakening (VW) asperities
surrounded by the Teflon velocity-strengthening (VS) patches, and (2) whether the sides of a VW asperity are confined with VS patches or are free surfaces. We found that increasing confinement by
reducing free surfaces or increasing the VW asperity aspect ratio stabilizes fault slip, so that higher normal stress is required to transition from aseismic to seismic slip. Increased confinement and high
aspect ratios also reduced M0 and increased fc, both of which were determined from the radiated seismic waves. M0 and fc were primarily controlled by the shorter dimension of the VW asperity. Analysis
of high-frequency acoustic emission signals revealed that ruptures on high-aspect-ratio VW asperities propagated more unidirectionally, whereas ruptures on square VW asperities were more complex. Further, the high-aspect-ratio asperities were more likely to be eroded by surrounding VS regions while lowaspect-ratio asperities were more likely to rupture into the VS surroundings. These results demonstrate that both the confinement from surrounding stable areas and the geometry of the seismogenic patch can affect rupture nucleation, propagation, and seismic source characteristics.This work was sponsored by National Science Foundation Grant EAR-2240375
