Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

Simulating iceberg calving

Understanding the physics of iceberg calving is a holy grail problem of glaciology. Progress on this problem has been slow in part because simulating any system with an evolving geometry is a major challenge. We have developed new approaches to simulating glacier flow with evolving termini, including both iceberg calving and the advance and retreat of ...

Calving giant icebergs: old principles, new applications

Antarctic Science, 2006
Earth-orbiting satellites can now monitor calving of large icebergs from ice shelves bordering the marine West Antarctic Ice Sheet, and recent calving events have stimulated interest in calving mechanisms. To advance this interest pioneering work in brittle and ductile fracture mechanics is reviewed, leading to a new application to calving of giant ...

The Role of Ice‐Rafted Debris (IRD) on Icebergs' Deterioration

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract During the last ice age, icebergs transported Ice‐Rafted Debris (IRD) more than 3,000 km across the North Atlantic. However, their effect on the deterioration of icebergs and thus where the deposits form is poorly understood. Laboratory experiments and a predictive model (with no fitting parameters) investigating the effects of sediment on ...

Carbon and water dynamics of Old World bluestem in the U.S. Southern Great Plains

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Forage production in the Southern Great Plains of the United States relies heavily on Old World bluestem (OWB, Bothriochloa spp.). This study analyzed 4 years (2021–2024) of continuous eddy covariance measurements in a managed OWB pasture in central Oklahoma, spanning both drought and wet periods.

Landsystems of the tropical high Peruvian Andes: Glaciers, lakes, wetlands and water resources in the Cordillera Vilcanota

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
We outline the geomorphological relationships between glaciers, lakes and bofedal wetlands, and the way in which moraines, talus slopes and sandar interact with catchment hydrology in the tropical Andes of Peru. Bofedales are well developed within glacial limits, with glacial processes such as erosion and formation of moraines providing the poorly ...

Disentangling the oceanic drivers behind the post-2000 retreat of Sermeq Kujalleq, Greenland (Jakobshavn Isbræ) [PDF]

The Cryosphere
Ocean temperatures have warmed in the fjords surrounding the Greenland Ice Sheet, causing increased melt along their ice fronts and rapid glacier retreat and contributing to rising global sea levels.

Observation and Coordination Needs for Current, Near‐Future, and Next Generation Earth‐Observing SAR Systems

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract This paper summarizes an evaluation by experts of how coordination of Earth‐observing Synthetic Aperture Radar (SAR) missions among the world's space agencies could advance toward game‐changing scientific discoveries and fully realizing SAR's practical capability to address many issues facing society.

The Variable Impact of Heinrich Events on the Benthic Environment of the Porcupine Abyssal Plain

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Heinrich events (HEs) are Pleistocene climate disturbances caused by massive freshwater discharges from the Laurentide Ice Sheet via the Hudson Strait. They appear in marine sediments as layers of ice‐rafted detritus (IRD) and significantly impact the benthic environment.
