The authors introduce state tomography, a quantum-mechanics-inspired methodology, for the quantitative measures of space-time "entangled" electromagnetic pulses, open new degrees of freedom to characterize the propagation dynamics of more general spatiotemporal waves, and report on its application to the propagation dynamics of general structured light, from single-cycle toroidal pulses and wideband polychromatic beams.

Osaka University researchers have developed a single-crystal cobalt phosphide nanorod catalyst for the reductive amination of carbonyl compounds to primary amines. The nanorod catalyst performed better than conventional catalysts, was stable in air, and was effective under mild conditions. Additionally, it could be reused multiple times without loss of activity. It is hoped that the nanorod catalyst will provide a green and sustainable alternative for the synthesis of valuable products such as pharmaceuticals.

According to a linguistic survey report, people often confuse the pronunciation of /hi/ with that of /si/ in the dialect of Tokyo and the Tohoku region of Japan. A team of researchers at Toyohashi University of Technology and the National Institute for Japanese Language and Linguistics (NINJAL) found that the confusion is resulted from the articulation of the tongue varying in the transverse direction while the tongue tip is positioned at the same place of articulation.

Researchers at the National Institute for Physiological Sciences in Japan reveal the mechanism of hyperkinetic movements called L-DOPA-induced dyskinesia, which is a major side effect of medication in Parkinson's disease.

The team discovered that a mere 10 nights of action are required to reduce risk to 50% of avian migrants passing over a given area in spring and autumn.

In the vast Colorado River basin, climate change is driving extreme, interconnected events among earth-system elements such as weather and water.

Researchers have created 3D molecular maps of bacteria, viruses, and biochemicals across coral colonies along with their interacting organisms such as algae and other competing corals. This allowed the team to discover specific microbial and viral functions that appear to be key components of the coral microbiome.

Researchers exploring the developing central nervous system of fruit flies have identified nonelectrical cells that transition the brain from highly plastic into a less moldable, mature state. The cells, known as astrocytes for their star-like shapes, and associated genes eventually could become therapeutic targets, researchers said.
