Some tiny passengers became astronauts. They rode around the Moon on Artemis I, and they came back having grown. According to a NASA Task Book report, all 20 fungus samples on the flight showed growth when they were examined after returning to Earth. The samples included a black mold, Aspergillus niger, and three mutant lab-made … Read more

A biological pigment produced by fungi could help plastic materials withstand the harsh environment beyond Earth, offering a promising direction for future spacecraft, orbital laboratories and long-duration space missions. In an experiment aboard the International Space Station (ISS), researchers found that adding fungal melanin to a plant-derived plastic significantly reduced material loss after approximately six … Read more

In 2020, Phoenix tested reflective roads to cool neighborhoods; pavement was up to 12°F cooler, but midday radiant heat for pedestrians rose

Phoenix tried a deceptively simple way to fight extreme urban heat: make its streets reflect more sunlight. The city’s 2020 Cool Pavement Pilot Program coated sections of residential roads in eight neighborhoods with a lighter, more reflective seal. The goal was to reduce the amount of solar energy absorbed by asphalt and, in turn, lower … Read more

In 1996, Columbia scientists tested Biosphere 2s ocean under ice-age, modern, and future CO2 levels; future conditions cut coral calcification by 40%

Every three months, an ocean in the Arizona desert took a trip through time. In 1996, Columbia University researchers used Biosphere 2’s marine mesocosm to recreate three sets of ocean conditions: those of a glacial ice age, the present day, and the 22nd century. According to the University of Arizona’s Biosphere 2 ecosystems page, the … Read more
