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 ...
