未来的火星定居者需要住房，但他们要么必须花费巨资从地球运输建筑材料，要么必须消耗巨量能量将火星土壤熔化成砖块。
Future settlers on Mars would need houses, but they must either spend huge sums transporting construction materials from Earth or use enormous amounts of energy to melt Martian soil into bricks.
香港科学家表示，他们开发出一种快速且低成本的“活体”建筑材料，由基因工程酵母、明胶和沙子制成，可在模拟火星环境的条件下进行3D打印。
Scientists in Hong Kong say they have developed a quick and low-cost “living” building material made from genetically engineered yeast, gelatin and sand that can be 3D printed under conditions simulating the Martian environment.
他们的研究于上月在线发表于《Chem Circularity》期刊，
Their study, published online last month in Chem Circularity, an...
