Disney Research produces 3D objects with variable elasticity using single material
Glendale CA (SPX) Aug 07, 2015 -
A 3D-printed teddy bear can have a stiff head, a pliable tummy and bendable arms, even though all of it is made of the same relatively stiff material, using a new method developed by Disney Research.
By using the printer to alter the small-scale structure of the material, the Disney researchers showed they could vary its elasticity dramatically within the same object. They developed famili ...

Two spin liquids square off in an iron-based superconductor
Upton NY (SPX) Aug 07, 2015 -
Despite a quarter-century of research since the discovery of the first high-temperature superconductors, scientists still don't have a clear picture of how these materials are able to conduct electricity with no energy loss. Studies to date have focused on finding long-range electronic and magnetic order in the materials, such as patterns of electron spins, based on the belief that this order un ...

Molecular trick alters rules of attraction for non-magnetic metals
Leeds, UK (SPX) Aug 07, 2015 -
Scientists have demonstrated for the first time how to generate magnetism in metals that aren't naturally magnetic, which could end our reliance on some rare and toxic elements currently used.
In a study led by the University of Leeds and published today in the journal Nature, researchers detail a way of altering the quantum interactions of matter in order to "fiddle the numbers" in a math ...

Timeline links volcanic eruptions to centuries of cold temp extremes
New Haven CT (SPX) Jul 09, 2015 -
A new study reorders the timing and reveals the climate impact of nearly 300 major volcanic eruptions worldwide, dating back to the early Roman period.
The analysis, published in the journal Nature, resolves longstanding inconsistencies between historic atmospheric sulfate data taken from ice cores and corresponding temperature data derived from tree rings and other sources. The new chrono ...

Peppermint oil and cinnamon could help treat and heal chronic wounds
Washington DC (SPX) Jul 09, 2015 -
Infectious colonies of bacteria called biofilms that develop on chronic wounds and medical devices can cause serious health problems and are tough to treat. But now scientists have found a way to package antimicrobial compounds from peppermint and cinnamon in tiny capsules that can both kill biofilms and actively promote healing.
The researchers say the new material, reported in the journa ...

Seafloor hot springs a significant source of iron in the oceans
Seattle WA (SPX) Jul 09, 2015 -
At the bottom of the sea, volcanic and magmatic forces create hot springs that spew super-heated water into the deep sea. The hot, acidic water scours metals from Earth's crust, and the warm chemical-rich water from these remote geysers supports exotic deep-sea ecosystems.
It had been widely thought the story stopped there. Metals such as iron and manganese were thought to quickly react an ...

NASA data shows surfer-shaped waves in near-Earth space
Greenbelt MD (SPX) Jul 09, 2015 -
The universe overflows with repeating patterns. From the smallest cells to the largest galaxies, scientists are often rewarded by observing similar patterns in vastly different places. One such pattern is the iconic surfer's waves seen on the ocean - a series of curled hills moving steadily in one direction.
The shape has a simple cause. A fast fluid, say wind, moving past a slower one, sa ...
