Researchers have developed a programmable synthetic temporal lattice using optical fiber loops to generate and synchronize chaotic light signals, providing a stable method for data transmission.

Researchers have achieved the world’s first demonstration of a gate-defined quantum dot in zinc oxide (ZnO), a material prized for qubit applications. Beyond confirming controlled single-electron behavior, the devices showed an unconventional Kondo effect appearing regardless of electron number—a surprising signature of ZnO’s strong electron correlations and a new platform for quantum technology research.

Researchers have developed a novel chemo-biological hybrid system that enables the direct synthesis of polylactic acid from CO₂, water, and renewable energy. By engineering Escherichia coli to utilize ethanol and acetate, this study establishes a sustainable route for bioplastic manufacturing that decouples agricultural feedstocks. The work highlights a synergistic cofeeding strategy that significantly enhances PLA titer, offering a promising solution to the environmental challenges associated with fossil-fuel and crop-based plastics.

In recent years, rapidly advanced space technology has resulted in a growing number of objects in orbit, including both operational and decommissioned spacecraft, as well as space debris, which pose potential threats to China’s on-orbit spacecraft. To ensure the safe operation of spacecraft in near-Earth and high-orbit environments, a key research focus in the field of space technology is the high-resolution and high-accuracy detection and perception of environmental objects under strong backlight conditions. Such capabilities are critical for providing timely early warnings to on-orbit spacecraft. However, a plethora of studies have demonstrated marked challenges in imaging dark and weak targets under strong light backgrounds. It is essential to analyze the challenges of current backlight imaging technologies, summarize the working principles of existing backlight detection methods, and explore future development trends.

Achieving regioselective C–H functionalization is a particularly difficult issue in organic chemistry when these C–H bonds have similar reactivity. Although significant progress has been made in regioselective C–H functionalization at one specific site, the tunable version of such processes is rarely documented. Here we describe a tunable meta- and para-selective C–H borylation of aryl and benzyl phosphonates, in which the regioselectivity can be switched by bifunctional ligands. A broad range of substrates are compatible and exhibit good to excellent regioselectivity under mild reaction conditions. Benzyl phosphonates can be conveniently transformed into styrene derivatives via Horner–Wadsworth–Emmons olefination. Gram-scale preparation and derivatization of borylated products demonstrate the important application of our method in synthetic chemistry. The orthogonality of two functional Bpin and phosphorylmethyl groups provides ample opportunity for increasing the diversity of styrene derivatives with precise site-control.
