A new “black smoker”–an undersea mineral chimney emitting hot springs of iron-darkened water–has been discovered at 8,500-foot depths by an expedition funded by the National Science Foundation (NSF) to explore the Pacific Ocean floor off Costa Rica.
Scientists from Duke University, the Universities of New Hampshire and South Carolina, and the Woods Hole Oceanographic Institution in [...]
Before fish began to invade land, about 365 million years ago, they had some big problems to solve. They needed to come up with new ways to move, breathe, and eat.
Take the latter, for example. Fish usually pucker up and suck prey into their mouths. But air is 900 times less dense than water, [...]
A new, complete ‘tree of life’ tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today.
The study was undertaken in the UK by scientists at Imperial College London and the Zoological Society of London [...]
Researchers using nanotechnology have taken a step toward creating an “optical cloaking” device that could render objects invisible by guiding light around anything placed inside this “cloak.”
The Purdue University engineers, following mathematical guidelines devised in 2006 by physicists in the United Kingdom, have created a theoretical design that uses an array of tiny needles [...]
Astronomers studying dwarf galaxies formed from the debris of a collision of larger galaxies found the dwarfs much more massive than expected, and think the additional material is “missing mass” that theorists said should not be present in this kind of dwarf galaxy.
The scientists used the National Science Foundation’s Very Large Array (VLA) radio telescope [...]
