Plaice in spaaace: NASA boosts astronauts' cognition with piscine diet
The booster diet included six servings of fruits and vegetables per day and between two to three servings of fish per week as well as other healthy foods."Subjects consuming the enhanced space flight diet had lower cholesterol levels, lower stress, better cognitive speed, accuracy, and attention, and a more stable microbiome and metatranscriptome [gene expression of microbes within natural environments] than subjects consuming the standard diet," the study said.
"Further investigation is required to fully develop dietary countermeasures to physiological decrements observed during spaceflight. These results will have implications for food resource prioritization on spaceflight missions," the study said.[PDF] to space nutrition describes how even missions as early as the Mercury program — an Apollo precursor which ran from 1958 to 1963 – helped contribute to the development of space food.
In the Apollo Moon missions, rehydratable food was encased in a plastic container referred to as the spoon bowl."Water was injected into the package through the nozzle of a water gun. After the food was rehydrated, a pressure-type plastic zipper was opened, and the food was removed with a spoon.

New study reveals hidden genetic anomaly behind common late-onset cerebellar ataxiaResearchers at the University of Miami Miller School of Medicine, McGill University and other institutions have found that a well-concealed genetic variation in the gene FGF14, called a DNA tandem repeat expansion, causes a common form of late-onset cerebellar ataxia, a brain disorder that interferes with coordinated movement. Tandem repeat expansions are only found in 50 conditions, including Friedreich's ataxia and Huntington's disease, but researchers believe they could account for many other conditions.
