Researchers from the University of Oxford and the University of Manchester have uncovered the mechanism behind the squirting cucumber's explosive seed dispersal using experiments, high-speed videography, and mathematical modeling. The study reveals that the plant's fruits become highly pressurized, redistributing fluid to the stem, which aids in the seeds' ballistic ejection. This unique dispersal strategy ensures optimal seed distribution and has potential applications in bio-inspired engineering, such as drug delivery systems.

Pilates can be an effective exercise regimen for alleviating knee pain, which affects about 25% of adults. Common causes of knee pain include osteoarthritis, injuries, and muscle imbalances. Pilates helps by strengthening the muscles supporting the knee, improving alignment, and enhancing flexibility. While not a cure-all, incorporating specific Pilates exercises can reduce knee pain by 20% to 30%. Experts recommend complementing these exercises with proper footwear, adequate protein intake, and maintaining an active lifestyle.
