AbstractThe I-/I0/I+ redox chemistry is hindered by the inherent instability of the electrophilic I+, which undergoes hydrolysis in aqueous media or is rapidly consumed by comproportionation with triiodide ions. Here, we design a copper single-atom embedded nitrogen-doped carbon host that synergistically combines d-p orbital hybridization and local low-concentration chloride ions to stabilize the I+. The atomic Cu-Nx sites interact moderately with iodine species through Cu d- and I p-orbital hybridization, which enhances iodine species adsorption, accelerates redox kinetics, and increases the hydrolysis energy barrier of I+. Simultaneously, the Cu-Nx sites promote a localized I-Cl microenvironment through electrostatic interaction, enabling efficient I0/I+ conversion even in a low-concentration Cl- ion electrolyte.

A team of researchers at NASA's Goddard Space Flight Center (GSFC) has developed a new instrument designed to eliminate blind spots between lines of lidar data on Earth's surface. Built with support from NASA's Earth Science Technology Office (ESTO), the Concurrent Artificially-intelligent Spectrometry Lidar System (CASALS) could help researchers map the features of Earth's surface in detail. Rather than mechanically steering a laser with moving mirrors, CASALS steers light using wavelength itself, generating a continuous, 3D swath of the ground below.

Langford diver Ryan Swan started his Be Sea Adventures channel on YouTube for myriad reasons. At the top of the list are education and conservation. The latest video focuses on a cleanup of the Salish Sea near Sidney. The waters between two piers at the base of Beacon Avenue became the focus this year. On Oct. 4, a team of volunteer divers and community partners did a permitted ghost gear cleanup, removing roughly 250 kilograms of abandoned crab traps, nets, rope, cable and line from the water.

Osaka, Japan – Whenever a cell divides, it has to split its chromosomes perfectly between two daughter cells, and even a single mistake can be disastrous. Now, researchers from Japan have found that one of the key structures that makes this possible takes a surprising shape: a hollow sphere. In a study to be published in Science Advances, researchers from the University of Osaka and their collaborators have revealed how a protein complex called the constitutive centromere-associated network (CCAN) assembles inside the cell, forming a spherical shell-like structure within the nucleus. CCAN sits at the centromere, the pinched 'waist' of each chromosome, where it forms the basis of a larger structure called the kinetochore. The kinetochore acts like a tow hitch - it links each chromosome to the cellular ropes that pull chromosomes apart during cell division. Although previous studies have revealed a single CCAN unit's structure in fine detail, each kinetochore contains dozens of these units, and consequently how they are arranged together inside cells has remained a mystery.

Keeping to warm climates throughout their 250-million-year history may have helped crocodiles and their relatives survive the asteroid that killed the dinosaurs, finds a new study led by UCL (University College London) researchers.
