Cold stress is a major environmental factor limiting grapevine cultivation, affecting yield, quality, and distribution. 

Fruit skin color is central to pear quality and market value, with russet skin offering both protection and unique appearance.

Cultured neural tissues have been widely used as a simplified experimental model for brain research. However, existing devices for growing and recording neural tissues, which are manufactured using semiconductor processes, have limitations in terms of shape modification and the implementation of three-dimensional (3D) structures.

By "thinking outside the box," a KAIST research team has successfully created a customized 3D neural chip. They first used a 3D printer to fabricate a hollow channel structure, then used capillary action to automatically fill the channels with conductive ink, creating the electrodes and wiring. This achievement is expected to significantly increase the design freedom and versatility of brain science and brain engineering research platforms.

This study uncovers a novel role of RNA G-quadruplex (rG4) structures in regulating translation and cellular senescence. By integrating ribosome profiling and rG4-RIP sequencing, the researchers reveal that rG4 structures within coding regions cause ribosome pausing, disrupt protein homeostasis, and accelerate senescence. The RNA helicase DHX9 is identified as a key factor that unwinds rG4 structures and maintains translational balance. These findings highlight rG4 stabilization as a potential driver of aging and age-related diseases, offering new therapeutic opportunities by targeting rG4 dynamics.

Researchers at Concordia and Qatar University have created a low-cost sensor system that tracks indoor air quality in real time.

The devices are built on tiny, affordable computers often used in research and do-it-yourself projects. Hooked up to sensors, they measure carbon dioxide, fine particles and nitrogen dioxide and volatile organic compounds (VOCs) like benzene, formaldehyde and acetone.

Data is sent wirelessly to an online dashboard, where users can view live charts and air quality indexes.

Gene editing in plants remains challenging, with the traditional non-homologous end-joining (cNHEJ) repair pathway often hindering precision.
