"Boosting Crop Size and Resilience: Harnessing Ethylene Hormone for Plant Priming"

Applying ethylene, a growth hormone commonly used to ripen fruit, to seeds in a specific dosing protocol has been found to enhance the size, strength, and stress tolerance of crops. Researchers discovered that by treating seeds with ethylene in darkness and tapering off the hormone when seedlings were exposed to light, plants exhibited increased root growth, taller stature, and more abundant leaves. The treated plants also showed improved productivity from photosynthesis and demonstrated better survival rates under harsh conditions such as high temperatures and salinity. The findings suggest that controlled application of ethylene could be a viable method to manipulate crop growth and enhance stress tolerance in specific growing conditions. Further research will explore the impact of ethylene treatment on the yield of fruiting crops.

"Revealing the Hidden Growth Secret of an Obscure Aquatic Plant"

Researchers at the John Innes Centre have discovered how plants prevent cracking during growth by studying an obscure aquatic plant, Utricularia gibba. They found that a dwarf mutant of the plant lacked a growth hormone called brassinosteroid, which normally allows the skin to stretch and prevent cracking. Computational modeling showed that the hormone loosens fibers in the epidermal cell walls, allowing the cells to coordinate growth. The findings have implications for understanding dwarfing varieties of crops and developmental processes in animals, and may help improve agricultural efficiency in the future.

NASA develops 3D-printed superalloy for extreme environments and nuclear space travel.

A team of materials scientists from NASA, The Ohio State University, and HX5 LLC have developed a 3D printing process that produces an alloy called GRX-810, which is much more resistant to stress than other alloys currently in use. The process involves adding a dusting of yttrium oxide powder to each layer of ink made of a mixture of cobalt, nickel, and chrome particles. The new alloy lasted for 6,500 hours in a creep test, compared to current top materials that typically last approximately 10 hours.
