Plant hormones that help roots reach deeper water offer potential strategy for drought-tolerant crops
Images of watering (left) and water stress (right) – showing changes in root angle to make the building steeper. Credit: University of Nottingham Scientists have discovered how plants adapt their root systems under drought conditions, growing rapidly into the soil to access deeper reservoirs. Plant scientists at the University of Nottingham, in collaboration with Shanghai Jiao Tong University, are investigating…

High-quality nanodiamonds offer new possibilities for bioimaging and quantum sensing
Researchers have developed nanodiamonds (NDs) with nitrogen vacancy (NV) centers that exhibit superior spin properties and fluorescence compared to commercially available NDs. These NDs exhibit longer spin relaxation times and require less microwave power for spin detection, making them ideal for quantum sensing of biological samples. Provided by: Masazumi Fujiwara, Okayama University Quantum sensing is a rapidly developing field that…

Cloud-inspired way to guide light: Waveguiding mechanisms could offer new ways to see inside the human body
Photon density modes in curved waveguides. Credit: Nature Physics (2024). DOI: 10.1038/s41567-024-02665-z Inspired by the way sunlight passes through clouds, scientists have discovered an entirely new way to control and direct light. This groundbreaking research, led by physicists at the University of Glasgow, allows light waves to be guided along curved paths tunneled through opaque materials that would normally scatter…

Affordable iron catalysts offer sustainable route to valuable Z-alkenes
This schematic illustrates the development of an iron-catalyzed dialkylation reaction that selectively converts arenes to the thermodynamically unfavorable Z isomer of trisubstituted alkenes. The reaction proceeds through transition states TS 1 and TS 2, each involving a different carbon-carbon bond formation chemical process. The high regioselectivity and Z-selectivity of this method make it a valuable tool for organic synthesis. Credit:…

Combined: Hybrid work models can offer the best of both worlds: worker well-being and productivity
Steven Blumenfeld, Chris Peace, Joan Crawford, Roya Gorgifard, The Conversation Credit: Unsplash/CC0 Public Domain Prime Minister Christopher Luxon this week ordered civil servants to return to work, sparking debate about the future of work in New Zealand. But Lacson’s order ignores broader changes to workplace culture. Driven by the rise in dual-income households and rapid technological advances, work-from-home (WFH) arrangements…
