The Perseids Break out the binoculars, folks. Time to see some shooting stars! As The Washington Post reports , the biggest and brightest meteor shower of the year, the annual Perseids, will be on full display this Saturday and Sunday.

Abstract We reveal a mechanism to enhance particle-matter interactions by exploiting the pseudo-Brewster effect of gain materials, presenting an enhancement of at least four orders of magnitude for light emission. This mechanism is enabled by the emergence of an unprecedented phase diagram that maps all phenomena of free-electron transition radiation into three distinct phases in a gain-thickness

Abstract Climate change–amplified marine heatwaves can drive extensive mortality in foundation species. However, a paucity of longitudinal genomic datasets has impeded understanding of how these rapid selection events alter cryptic genetic structure. Heatwave impacts may be exacerbated in species that engage in obligate symbioses, where the genetics of multiple coevolving taxa may be affected. He

Abstract Spin-waves in antiferromagnets hold the prospects for the development of faster, less power-hungry electronics and promising physics based on spin superfluids and coherent magnon condensates. For both these perspectives, addressing electrically coherent antiferromagnetic spin-waves is of importance, a prerequisite that has been so far elusive, because, unlike ferromagnets, antiferromagne

Abstract Dopamine is broadly implicated in reinforcement learning, but how patterns of dopamine activity are generated is poorly resolved.

While engaging in cell division research, researchers made a surprisingly quiet discovery. When cells express RNA, there is always some fluctuation, or noise, in how much RNA is produced. The scientists found several genes whose noise dips below a previously established threshold, known as the noise floor, during expression.

Scientists have conducted a study of the interface between two liquids, focusing on a force called interfacial tension. Their numerical simulation helped them better understand the mechanism at work in interfacial tension. This work contributes to the understanding of interfacial fluid dynamics. It offers potential applications in a variety of fields ranging from oil recovery to medical use.

Double fertilization is a complex mechanism in flowering plants, wherein two sperm cells fuse with the embryo sac. To achieve this, pollens released from anthers must interact with the plant's stigma, hydrate, and germinate into pollen tubes. Thus, pollen tube germination and elongation are crucial for double fertilization, which, in turn, influences the grain yield of crop plants.

Mountain ranges play a key role in global climate, altering weather and shaping the flora and fauna that inhabit their slopes and the valleys below.

Thus, the way mountain ranges form is a matter of intense interest am
