Summary: Using ocean simulations and sediment carbon isotope records, the study suggests that vertical mixing in the Atlantic Ocean during the Last Glacial Maximum may have been enhanced due to more vigorous tidal dissipation, rather than reduced.

Summary: This study aims to assess how molecular abundances and corresponding spectra can be used as a probe of depth-dependent K(zz) with a new grid of self-consistent 1D model atmospheres. Nonmonotonic behavior in CO abundance with T(eff) and variations in temperature structure and chemical quenching behavior with gravity were observed.

Summary: This study proposes a data-driven parameterization model based on artificial neural networks to improve the simulation accuracy of ocean and climate models. By utilizing long-term turbulence measurements, the model achieves higher accuracy and demonstrates good generalization ability under physical constraints, outperforming traditional physics-driven parameterizations.

Summary: By investigating vertical phase mixing across the Galactic disk, it was discovered that grouping stars by guiding radius enhances snail shell signals, showing more wraps and improved contrast, ultimately amplifying the phase space snail shell across greater radial ranges. The results suggest that the guiding radius is a fundamental parameter tracing phase space snail shells, and using it with constraints on orbital hotness can lead to clearer phase space observations.

Summary: This study compares the effects of four different ocean vertical mixing schemes on the mean state of the ocean and atmosphere, with the TKE+IDEMIX scheme leading to warmer sea surface temperatures in the North Atlantic and Nordic Seas. This scheme strengthens the Atlantic meridional overturning circulation, enhancing northward heat transport and inflow of warm and saline water from the Indian Ocean.

Summary: The article discusses a technology for pulse compression using hollow-core fibers and identifies an unexplored mechanism for generating visible-light pulses with few cycles. Using a commercial ytterbium laser, they successfully convert few-hundred-femtosecond-long infrared pulses into single-cycle visible light pulses.

Summary: Research shows that turbulent mixing generated by the swimming activity of marine organisms can be as efficient as geophysical turbulence, enhancing vertical mixing in the ocean. This has significant implications for productive upper ocean regions.

Summary: Measuring vertical motions is challenging due to their small magnitude compared to horizontal velocities. This study demonstrates that surface vertical velocities are intensified at submesoscales and are influenced by high frequency variability. The use of a multi-layered drifter array proves to be an effective tool for estimating vertical velocities near the ocean surface.

Summary: The seasonal features of the eastward jet through the Tsugaru Strait were investigated, and it was found that the volume transport of low potential vorticity water and an increase in the local PV gap can influence the seasonal flow pattern of the Tsugaru Warm Current.

Summary: The study demonstrates that iPSC-derived brain organoids generated through vertical mixing exhibit an inverted structure with neurons localized at the center and neural progenitors at the outer periphery. The research highlights the impact of fluid mechanics relevant to the direction of primary cilia on stem cell differentiation.

Summary: This paper examines the effects of ownership mixing and vertical unbundling on the SO2 emission intensity of electricity generation firms. The study finds that ownership mixing not only improves access to electricity and generation efficiency, but also significantly reduces firms' air pollution intensity. On the other hand, vertical unbundling has no significant effects on firms' air pollution. These findings provide an effective and environmentally friendly pathway for electricity industry restructuring in developing countries.

Summary: This study investigated the vertical distribution of organic matter within sea ice and found that both the bottom and upper sections of the ice contained organic matter, predominantly contributed by marine autotrophs. The particulate matter within the ice could potentially serve as an additional food source for higher trophic grazers or act as a seeding material for phytoplankton blooms during the ice melting season.
