SETI keeps looking up

The search for extraterrestrial life is serious science: its methods are precisely documented, its results painstakingly peer-reviewed. But at the same time it’s a field with curious standards when it comes to “advances.”

Printing out the orbital infrastructure

3-D printing is going viral. With 3-D fabrication technology at for the desktop, for LEGOs, and for nanoscale materials, it was only a matter of time before the paradigm found its way into space—and corporate science fiction. But this promising technology still has to prove itself in terrestrial infrastructure first.

And with numerous spacecraft now beaming back publicly-available images from our neighboring planet, Martian fantasizing is a growth industry. This film is one of the most convincing, and it isn't even from Mars. Video after the jump.

Narwhals join climate debate

Narwhals don't go to graduate school, and they're not much use as grant-writers. But they're able to do a few things oceanographers find challenging—such as dive to depths of nearly six thousand feet beneath the ice of Baffin Bay in winter. So scientists have enlisted them in gathering climate-change data in the Greenland Current.

Corporate Sci-Fi: the Luna Ring

The Tokyo-based Shimizu Corporation is one of the world's leading construction and engineering contractors. It's also a prolific producer of corporate science fiction: fanciful, high-concept design projects that offer glimpses of astonishing futures. Its "Luna Ring" envisions such a future for the moon—and for Shimizu.
