The father of evolution apparently played God with a tropical ecosystem 160 years ago, and the results could inform future experiments to terraform Mars, botanists say.
The BBC recounts how Charles Darwin helped build an artificial forest on Ascension Island, one of his subjects of study from his trips on the HMS Beagle. Today, the island is home to species of plants that would not naturally co-exist. Darwin and his friends put them there, and nearly two centuries later, their grand experiment is living proof that we can transform natural environments.
If we ever decide to colonize Mars, it might be fairly simple to grow crops in that red soil, according to a new study. Mars’ reduced gravity could let us use less water and fertilizer than we do on Earth.
When PopSci published Will Snyder's article on terraforming Mars, we opined that the Mars Society's colonial flag could use some sprucing up, so we asked readers to submit their own designs. The week the article appeared, 42 Martian-flag mockups turned up in our inbox. Some featured elaborate designs and detailed explanations (which we've printed in their entirety in the slideshow), while others simply included a name. A couple flags were even sent anonymously.
