Imaging through diffusers presents a challenging problem with various digital image reconstruction solutions demonstrated to date using computers. Here, we present a computer-free, all-optical image reconstruction method to see through random diffusers at the speed of light. Using deep learning, a set of transmissive diffractive surfaces are traine...

Spatial synchrony is a ubiquitous and important feature of population dynamics, but many aspects of this phenomenon are not well understood. In particular, it is largely unknown how multiple environmental drivers interact to determine synchrony via Moran effects, and how these impacts vary across spatial and temporal scales. Using new wavelet stati...

Plastics are synthetic polymers that are extensively used in the modern world, and subsequently abandoned causing severe challenges and destruction to the natural environment. Though initially considered as synthetic replacements to finite natural materials, these have become serious pollutants in every sphere of the Earth, and earning the dubious...

Decades of research have revealed relationships between the abundance of coral reef taxa and local conditions, especially at small scales. However, a rigorous test of covariation requires a robust dataset collected across wide environmental or experimental gradients. Here, we surveyed spatial variability in the densities of major coral reef functio...

Plain Language Summary We examined forecasts for three hurricanes in 2020 that intensified near landfall. Using a coupled air‐sea hurricane model, we found that tropical storm‐force winds blowing parallel to the coast forced water near the ocean surface to move toward shore. Winds often blow parallel to the coast when tropical cyclones (TCs) (hurri...

By not only relying on the initial state but also relying on states before, the principle of a self-retrospect dynamic system has been developed to represent the changes in a system since 1991. Afterward, the periphery theory was established, which studies the boundary of a system. We try to integrate the principle of the self-retrospect system and...

The oceans represent 97% of all water on Earth and contain microscopic, drifting life, plankton, which drives global biogeochemical cycles. A major hurdle in assessing marine plankton is the planetary scale of the oceans and the logistical and economic constraints associated with their sampling. This difficulty is reflected in the limited amount of...

The analysis of 14 years of sampling data on the zooplankton community in southern Brazil showed a tendency toward increased density and reduced species richness. This behavior could be a response to a prolonged period of negative sea surface temperature (SST) anomalies in the Pacific Ocean and the ENSO phenomenon. The persistence of the La Niña ph...

During the Quaternary, some vertebrates lived on a variety of islands, from large to small, close to and far from the mainland. Their ancestors arrived at these islands mainly via chance dispersal, swimming across wide or narrow water barriers, rafting on floating vegetation, drifting with the aid of currents, or crossing over on discontinuous, tem...

The warming of the surface ocean is expected to increase the stratification of the upper water column. This would decrease the efficiency of the wind-induced mixing, reducing the nutrient supply to the euphotic layer and the productivity of the oceans. Climatic projections show that the Mediterranean Sea will experience a strong warming and salting...
