In modern airliners, much of the structural paneling used in the cabin and wings has a honeycomb-like structure.

When people are attempting to clean up oil spills at sea, one of the key things they need to know is the amount of oil that's been spilled – among other things, this will determine the amount of dispersant or other agents that are used.

Acoustic levitators are already pretty intriguing devices, in that they use opposing sound waves to suspend small objects in mid-air. Now, however, scientists from Brazil's University of São Paulo have created what they claim is a better acoustic levitator. It's less fussy about the exact orientation of its components, making it more feasible for use in practical applications. Read More

If you're ever trapped in a collapsed building and are calling for help, you might want to think twice before squashing any cockroaches that wander your way – one of them might have been sent to find you. Researchers from North Carolina State University are currently laying the groundwork for such a scenario, by getting cyborg-like "biobot" cockroaches to move towards sounds. Down the road, such insects may be used to locate victims at disaster sites. Read More
