Unearthed ancient ruins, extended art awards, astronaut urine and more in our look around the internet

Astronaut Urine Will Be a Valuable Resource on the Moon Since the cost of shipping resources to the moon remains prohibitively high, planning for long stints—or even habitation—requires savvy, as the rugged surface (aka regolith) restricts growth. Earlier this year, researchers found that, when mixed with moon dirt, astronaut urine could be a remarkably useful building material. When urea, “the second-most common compound in human …

Concrete 3D-Printed House Built in 48 Hours

Working in collaboration with developer Buřinka (aka Stavebni Sporitelna Ceske Sporitelny), sculptor Michal Trpák has designed a 43-square-meter concrete house called Prvok—a structure that can be 3D-printed in just 48 hours and will float on water. The first of its kind in the Czech Republic, the house’s building process not only cuts construction costs, reduces CO2 emissions by 20% and minimizes waste, but the resulting …

Scientist-Invented Carbon Nanostructure That’s Stronger Than Diamonds

Scientists from several institutions (including the University of California, Irvine) have conceptualized and fabricated a new class of plate-nanolattices (nanometer-sized carbon structures) that happens to be stronger than diamonds. They’ve done so through a complex 3D laser printing process referred to as “two-photon polymerization direct laser writing.” Scientists begin by focusing a laser on a drop of ultraviolet-light-sensitive liquid resin. It’s in the final material’s …
