A slowing Atlantic Ocean current is projected to reshape global rainfall patterns, intensifying powerful storms in California while reducing snowfall over Greenland, according to a new University of California, Riverside study.

An ongoing research project exploring the effects of rising levels of oceanic CO₂ on squid neurology reveals that exposure to future levels of ocean acidification could shrink their brain volume by around 50%. This severe brain shrinkage appears to be most pronounced in the areas that interpret visual information, correlating with significant reductions in normal feeding behaviours and suggesting serious consequences for the future of squid and other cephalopods.

To meet the requirements for electromagnetic wave (EMW) absorbing materials in corrosive environments such as the ocean, (NiZnCuMn)Co₂O₄ medium-entropy oxides (MEOs) with anticorrosion properties have been developed as novel EMW absorbing materials. The (NiZnCuMn)Co₂O₄ MEOs, which are synthesized via a hydrothermal reaction followed by calcination, exhibit robust EMW absorption performance with a minimum reflection loss of −64.05 dB and an ultrabroad effective absorption bandwidth that can reach 7.35 GHz by adjusting the hydrothermal reaction time. This high performance is attributed to the synergistic effect of dielectric loss, magnetic loss, and the unique structure of the MEOs. (NiZnCuMn)Co₂O₄ can be doped into epoxy resin, endowing it with excellent anti-corrosion properties. After being soaked in 3.5 wt.% NaCl for 14 days, (NiZnCuMn)Co₂O₄ prepared with a hydrothermal time of 12 h, shows a minimum corrosion current of 6.61 × 10⁻⁶ A cm⁻². When the hydrothermal time is 18 h, the corrosion current is 6.66 × 10⁻⁶ A cm⁻² and the corrosion potential reaches −0.712 V. This study provides new insights into the design of EMW absorbing materials with anticorrosion properties.

Why do some coral reefs weather marine heatwaves better than others? A new study published in Scientific Reports shows that the answer may lie not only in local ocean conditions, but also in climate patterns that span entire ocean basins. By combining long-term ocean observations with chemical records preserved in coral skeletons, the researchers reveal how large-scale climate oscillations regulate the natural cooling that can help protect coral reefs during marine heatwaves. First author Dr. Hana Camelia and Dr. Thomas Felis from MARUM – Center for Marine Environmental Sciences at the University of Bremen lead the study.
