Innovative approach makes for a smoother ride

Moving through water can be a drag, but the use of supercavitation bubbles can reduce that drag and increase the speed of underwater vehicles. Sometimes these bubbles produce a bumpy ride, but now a team of engineers from ...

Faster, portable microbial analysis in the field

Until recently, it took hours – sometimes days – to analyze biological samples after they were frozen in the field and brought back to the laboratory. But now there is a faster, cheaper and smaller way for researchers ...

Engineers hand "cognitive" control to underwater robots

For the last decade, scientists have deployed increasingly capable underwater robots to map and monitor pockets of the ocean to track the health of fisheries, and survey marine habitats and species. In general, such robots ...

Diverse sea creatures evolved to reach same swimming solution

The ability to move one's body rapidly through water is a key to existence for many species on this blue planet of ours. The Persian carpet flatworm, the cuttlefish and the black ghost knifefish look nothing like each other ...

Stunning finds from ancient Greek shipwreck

A Greek and international team of divers and archaeologists has retrieved stunning new finds from an ancient Greek ship that sank more than 2,000 years ago off the remote island of Antikythera. The rescued antiquities include ...

As ice cover disappears, life in the frigid Antarctic moves fast

It might be cold in the Antarctic, but that doesn't mean that life there necessarily moves slowly. A report appearing in Current Biology, a Cell Press publication, on July 11 reveals the discovery of a surprisingly fast-growing ...

Tiny reef speedster challenges tuna in the ocean sprint

(Phys.org)—Tiny coral reef wrasses can swim as fast as some of the swiftest fish in the ocean – but using only half as much energy to do so, Australian scientists working on the Great Barrier Reef have found.
