A team of scientists presents an original oscillating short-term memory model to study the dynamics of landing events at 10 major European airports. The model can estimate how landing volumes will influence those in consecutive hours — a critical ability given airport capacity constraints and external events that cause landing delays. Altogether, the model demonstrates that statistical analyses o

Abstract Lattice light sheet microscopy excels at the noninvasive imaging of three-dimensional (3D) dynamic processes at high spatiotemporal resolution within cells and developing embryos. Recently, several papers have called into question the performance of lattice light sheets relative to the Gaussian sheets most common in light sheet microscopy. Here, we undertake a theoretical and experimenta

Abstract A major unresolved issue in biology is why phenotypic and genetic variation is sometimes continuous, yet other times packaged into discrete units of diversity, such as morphs, ecotypes, and species. In theory, ecological discontinuities can impose strong disruptive selection that promotes the evolution of discrete forms, but direct tests of this hypothesis are lacking. Here, we show that

Abstract Achieving percolation pathways in a metal-organic framework (MOF)–based mixed matrix membrane (MMM) without compromising its mechanical properties is challenging.

Abstract A theory is developed to describe the topological Langmuir-cyclotron wave (TLCW), a topological excitation in magnetized plasmas recently identified by numerical simulations. As a topological wave in a continuous medium, the TLCW propagates unidirectionally without scattering in complex boundaries and can be explored as an effective mechanism to energize particles. We show that, because

Engineering researchers have developed a novel way to capture carbon dioxide from the air and store it in the 'infinite sink' of the ocean. The approach uses an innovative copper-containing polymeric filter and essentially converts CO2 into sodium bicarbonate (aka baking soda) that can be released harmlessly into the ocean. This new hybrid material, or filter, is called DeCarbonHIX (i.e., decarbon

Standard cosmology can answer almost nothing about how the structure of a galaxy is formed. Why the visible matters of a disk galaxy are distributed in a thin plane as opposed to how dark matter occurs in a spherical distribution is a critical open question. In a paper recently published in Reports in Advances of Physical Sciences, Dr. Nagao offers a promising theory of galaxy formation. Simulatio

Microelectronics forms the foundation of much modern technology today, including smartphones, laptops and even supercomputers. It is based on the ability to allow and stop the flow of electrons through a material. Spin electronics, or spintronics, is a spinoff. It is based on the spin of electrons, and the fact that the electron spin along with the electric charge creates a magnetic field.

Many mammals suffer hearing loss in old age, but bats were thought to be immune to this phenomenon because of the importance of hearing for echolocation. However, researchers in Israel have discovered that bats lose their hearing in old age just like humans do.

Coastal ecosystems are a natural storehouse for carbon, with policymakers looking to bays, marshes, and seaside forests as nature-based solutions to help combat climate change. But the capacity of these ecosystems to take up carbon dioxide from the atmosphere depends on diverse and often conflicting factors, including sediment supply, coastal slope, tidal range, wave climate, and changes in sea le

What makes this feat unique is that the new molecule is chiral, which means it has

In 1922, French physicist Léon Brillouin predicted an interesting phenomenon—when light is shone on a material, it interacts with the naturally occurring thermal vibrations within it, exchanging some energy in the process. This, in turn, influences how the light is scattered. By measuring the spectrum (color) of the scattered light, we can deduce certain physical characteristics of that material.
