Caltech Scientists Unlocking a Mystery of Human Disease . . . in Space

The work of Owens and Bjorkman featured in a CASIS ARK1 video. Credit: CASIS ARK1 video via ISSCASIS/YouTube   An experiment just launched into orbit by a team of Caltech researchers could be an important step toward understanding a devastating neurodegenerative disease. Huntington’s disease is a grim diagnosis. A hereditary disorder with debilitating physical and cognitive symptoms, the disease usually robs adult patients of their ability…

Building Better Soybeans for a Hot, Dry, Hungry World

A soybean field in Ohio. Image credit: WikiMedia Commons A new study shows that soybean plants can be redesigned to increase crop yields while requiring less water and helping to offset greenhouse gas warming. The study is the first to demonstrate that a major food crop can be modified to meet multiple goals at the same time. The study, led by Darren Drewry of NASA’s Jet Propulsion Laboratory used an advanced vegetation model and high-performance computer optimization techniques. It found that by redesigning soybean plants in various ways, it was possible to increase soybean productivity by seven percent without using…
