Fish simulations provide new insights into energy costs of swimming

A new computational analysis suggests that maximizing swimming speeds while minimizing energy costs depends on an optimal balance between a fish's muscle dynamics and the way its size, shape, and swimming motion affect its ...

Researchers report a fundamental muscle speed limit

When birds sing, bats echolocate, rattlesnakes rattle, and toadfish hum, they use so-called superfast muscles, the fastest vertebrate muscles known. New research shows that these muscles have reached a maximum speed attainable ...

Size key to top speed in animals, study finds

It's not quite E=mc2, but scientists unveiled Monday a simple, powerful formula that explains why some animals run, fly and swim faster than all others.

Swedish student startup gets deal to build electric cars

A group of Swedish university students that raised 1.2 million euros ($1.3 million) in crowdfunding for their startup to build electric cars has caught the attention of German industrial heavyweight Siemens.

NASA measures winds of Tropical Storm Conson
