New research shows the Venus flytrap closes its trap not by water redistribution but via rapid softening of the outer epidermal cell walls (about 30–40%), releasing internal stresses and triggering a snap-buckling that can seal prey in as little as 0.1 seconds; the finding revises a century-old hypothesis and could spur advances in soft robotics and smart materials.
Researchers use a new leaf-imaging system that combines microscopy, gas sensors, and controlled environments to video-record stomatal openings in living leaves, linking pore movements to CO2 uptake and water loss in real time and highlighting variability among pores—offering a tool to help breeders improve crop water-use efficiency.
UIUC's Stomata In-Sight integrates confocal microscopy, leaf gas exchange, and machine-learning analysis to observe stomatal openings and real-time gas transfer in maize, linking pore-scale dynamics to leaf-level water-use efficiency and photosynthesis.
New research suggests that plants may be able to absorb more atmospheric CO2 than previously believed, offering hope in combating climate change. The study found that incorporating critical physiological processes in plant modeling resulted in stronger and sustained carbon uptake until the end of the 21st century. However, scientists emphasize the continued importance of reducing emissions, as planting trees alone is not a sufficient solution. The findings highlight the potential of nature-based solutions like reforestation and afforestation in mitigating climate change, but emissions reduction remains crucial.
