Horses have been shown to be able to distinguish between angry and happy human facial expressions, according to psychologists who studied how 28 horses reacted to seeing photographs of positive versus negative human facial expressions.

Boulder, Colo., USA - Seismic, deformation, and gas activity (unrest) typically precedes volcanic eruptions. Tracking the changes of this activity with monitoring data makes it increasingly possible to successfully forecast eruptions from stratovolcanoes. However, this is not the case for monogenetic volcanoes (usually the result of a single magmatic pulse). Eruptions from these volcanoes tend to be small but are particularly difficult to anticipate since they occur at unexpected locations, and there is very limited instrumental monitoring data.

A new paper finds that China's new efforts to price carbon could lower the country's carbon dioxide emissions significantly without impeding economic development over the next three decades.

Australian researchers have found biochemical changes occurring in the blood, in the rare inherited form of Alzheimer's disease. Changes in these fat-like substances, may suggest a method to diagnose all forms of Alzheimer's disease before significant damage to the brain occurs.

In an article published today in the Journal of Alzheimer's disease, the Australian team led by Professor Ralph Martins from the CRC for Mental Health and Edith Cowan University, examined the lipid profiles of 20 people who carry a mutation responsible for the rare inherited form of Alzheimer's, known as familial Alzheimer's disease.
