Problem-solving by evolution and human creativity often take odd turns. Some solutions combine disparate elements, like armor and eyes, or driving and flying. Others follow more linear paths by redesigning the same concept over and over with minor changes. 

This week, follow the reincarnations of NASA's latest research aircraft; meet the algae-infused salamander; travel in style with some flying cars; and watch the first controlled landing of the Blue Origin rocket.

Three high-flying birds soar together for the first time since the 1970s

 to monitor hurricanes, study atmospheric effects of rocket launches and fulfill other high-altitude missions. NASA expanded the WB-57 fleet to three by completing the restoration and refit of a B-57, and celebrated by flying all three together at the Johnson Space Center. 

Each of the WB-57s began life as a standard B-57 medium bomber, then were rebuilt during the 1960s into RB-57s with much larger wings and more powerful engines to fit a high-altitude reconnaissance role. 

Retired by the military in the early 1970s, NASA modified a handful of the planes into WB-57s. Some of the RB-57s were mothballed in Arizona. The 

 was in long-term storage from 1972 to 2013. 

This animal has a suit of armor with hundreds of built-in eyes

Unlike other mollusks that rely on complete armor — like clams — or squishy dexterity — like octopi — the chiton has gone the path of panoptic armor. It combines a hard, armoring shell with a network of primitive eyes with calcium carbonate lenses, allowing it to watch the sea around it through its shell. 

The long, weird history of the flying car

Ever since humans noticed birds in the sky, we've attempted to emulate them while bringing a bit of comfort, and style, to the skies. 

An algae-supercharged salamander provides a road map to previously unknown symbiosis between organisms.
