Observational and numerical assessment of meteorological characteristics and climate variabilities over the Antarctic Peninsula in recent decades

Abstract The Antarctic Peninsula (AP) exhibits pronounced spatial variability in recent climate trends, with contrasting temperature changes between the West Antarctic Peninsula (WAP) and East Antarctic Peninsula (EAP). This study provides an observational and numerical assessmen...

The parent bodies of Ryugu and Ivuna formed before those of other carbonaceous chondrites

Most carbonaceous chondrite (CC) meteorites contain abundant chondrules, millimeter-scale spherical inclusions of previously molten material. Ivuna-type carbonaceous chondrites (CIs) do not contain chondrules, nor do samples of the carbonaceous asteroid Ryugu. CIs and Ryugu share...

Effects of the complexity of the ocean model on the sea ice data assimilation in a coupled sea ice-ocean model

Abstract The ocean plays a crucial role in the formation and melting of sea ice, which also affects the performance of sea ice data assimilation. To evaluate how ocean model complexity affects the assimilation performance, the sea ice model is separately coupled with two distinct...

Immunogenic Cell Death Induced by EEO in Breast Cancer Cells Promotes Dendritic Cell Activation in a CRT-Dependent Manner

Cancer immunotherapy faces significant challenges in treating “cold” tumors, which respond poorly to current strategies. Breast cancer is a major cause of cancer-related mortality in women and is a representative immunosuppressive cold tumor. The luminal A subtype of breast cance...

Delayed submarine caldera subsidence creates extreme tsunami hazard

The 2022 Hunga volcano eruption generated one of the largest and most destructive volcanic tsunamis ever recorded. We interpret the timing, nature and relative hazard of volcanic-tsunamigenic processes by combining geophysical, oceanographic, atmospheric, and eye-witness observat...

Winter sediment resuspension in a submarine canyon drives the offshore export of toxigenic Alexandrium catenella cysts

Abstract Harmful algal blooms (HABs) caused by the toxigenic dinoflagellate Alexandrium catenella recur regularly in the Lower St. Lawrence Estuary (LSLE, eastern Canada). Using quantitative polymerase chain reaction (qPCR) to detect A. catenella DNA as a proxy for cyst abundance...
