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.

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 ...
