Mars shelter problem can be solved with engineered yeast: paper - South China Morning Post

Scientists investigating why the Moon's two sides look so different have uncovered new evidence that could help explain this long-standing mystery. A research team led by Professor Hejiu Hui of Nanjing University analyzed lunar rocks collected by China's Chang'e-6 (CE6) mission and found clues suggesting that enormous movements of molten rock shaped the Moon billions of years ago. The researchers examined the chemical compositions of three types of lunar rock: anorthosites, Mg-suite rocks, and mare basalts. They compared these samples from the Moon's far side with material collected from the near side during the Apollo and Chang'e-5 missions. Their findings suggest that the Moon's striking differences emerged through large-scale heat-driven circulation within its ancient lunar magma ocean (LMO), after the Moon became tidally locked to Earth.

About a century ago, archaeologists excavating pottery fragments around Tampa Bay encountered something puzzling. Some of the pieces carried decorations that looked strikingly similar to pottery found hundreds of miles farther north. On appearance alone, the fragments seemed connected to the Mississippian culture, which emerged more than 1,000 years ago and reshaped social, economic and political life across much of southeastern North America. For decades, however, maps of the Mississippian world generally left out peninsular Florida. The Tampa Bay pottery suggested that the region's relationship with that culture may have been more complicated.
