Coil design confines plasma in stellarator fusion reactor
|
Researchers from New York University have designed a configuration of coils for a stellarator, a type of device that controls fusion reactions. The shape, number and position of the coils are optimized to generate an external magnetic field for the stellarator that will prevent the hot plasma from deteriorating.

Engineers develop higher-energy liquid-transportation fuel from sugar
|
Plants absorb carbon dioxide from the air and combine it with water molecules and sunshine to make carbohydrate or sugar. Variations on this process provide fuel for all of life on Earth.

Pieces of Catalyst Puzzle Explained
|
Catalysts speed up chemical reactions, as in your car’s catalytic converter, and they even double as clichés, as in “catalyst for change,” but how they work remains a mystery.

Famous Supernovae Still Echo Across the Milky Way
|
In 1572, the Danish astronomer Tycho Brahe observed and studied the explosion of a star that became known as Tycho's supernova. More than four centuries later, Chandra's X-ray photograph of the supernova remnant shows an expanding bubble of multimillion degree debris (green and red) inside a more rapidly moving shell of extremely high energy electrons (filamentary blue). Astronomers have detected a light echo from this supernova, meaning they can see the light from the explosion itself 400 years later. |

Movement of nanomaterials in food chain
|
New research in Nature Nanotechnology shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms. The preliminary results observed by researchers from the National Institute of Standards and Technology suggest that the particular nanomaterials studied may not accumulate in invertebrate food chains.

The Surprising Truth Behind the Construction of the Great Pyramids
|
This Behind the Scenes article was provided to LiveScience in partnership with the National Science Foundation.
“This is not my day job.” So begins Michel Barsoum as he recounts his foray into the mysteries of the Great Pyramids of Egypt. As a well respected researcher in the field of ceramics, Barsoum never expected his career to take him down a path of history, archaeology, and “political” science, with materials research mixed in.

Digital Tricks Preserve Thousands of Dinosaur Tracks
|
Digital technology has “frozen in time” thousands of fossilized dinosaur tracks, bringing to life a caravan of paleo-beasts, from towering sauropods to Tyrannosaurus rexes, that stampeded over a rocky Earth millions of years ago.

Genetic mutation linked to walking on all 4s
|
What are the genes implicated in upright walking of humans? The discovery of four families in which some members only walk on all fours (quadrupedality) may help us understand how humans, unlike other primates, are able to walk for long periods on only two legs, a scientist will tell the annual conference of the European Society of Human Genetics today.

When is a worm not a worm?
|
One of the world’s strangest creatures has found its long-lost kin. Oxford University scientists have discovered that an extremely rare gutless worm is related to sea anemones and jellyfish, rather than similar-looking animals, reports this week’s Science. The finding could cause an evolutionary rethink.
