Bird echolocation inspires new engineering

All animals use a combination of senses to survive. But where the majority typically rely on one or two especially sensitive sensory systems, the oilbird excels by apparently having keen senses all-around.

Enough oxygen long before animals rose

Oxygen is crucial for the existence of animals on Earth. But, an increase in oxygen did not apparently lead to the rise of the first animals. New research shows that 1.4 billion years ago there was enough oxygen for animals ...

A common mechanism for human and bird sound production

When birds and humans sing it sounds completely different, but now new research reported in the journal Nature Communications shows that the very same physical mechanisms are at play when a bird sings and a human speaks.

Scientists bring oxygen back to dead fjord

More and more of the world's waters are seriously lacking oxygen. Could we use pumps to bring oxygen and thus higher life back into these waters? A Danish/Swedish research team says yes. They installed pumps in a Swedish ...

Physicists suggest new way to detect dark matter

For years physicists have been looking for the universe's elusive dark matter, but so far no one has seen any trace of it. Maybe we are looking in the wrong place? Now physicists from University of Southern Denmark propose ...

Maybe it wasn't the Higgs particle after all

Last year CERN announced the finding of a new elementary particle, the Higgs particle. But maybe it wasn't the Higgs particle, maybe it just looks like it. And maybe it is not alone.
