The volcano that changed the world

Eruption in 1600 may have plunged the globe into cold climate chaos.

Did the Huaynaputina volcano, seen here from a satellite, inflict misery on the world?ASTER Volcano Archive

Four centuries ago, a Peruvian volcano blew its top – and the whole world may have felt it, a new study suggests.

The eruption in 1600 of Huaynaputina, a stratovolcano in the Andes mountains, blanketed nearby villages with glowing rock and ash, and killed some 1,500 people. But it may also have had a far wider effect, by injecting sulphur particles high into the atmosphere and disrupting the climate worldwide.

Equine Bone Fragility Disorder Reported in California

eterinary researchers at the University of California, Davis, are working to classify a newly observed bone fragility disorder that might prove to be the culprit behind some cases of intermittent chronic lameness that have no other explanation.

After an extensive review of medical records from horses examined at the university's Veterinary Medical Teaching Hospital between June 1980 and June 2006, researchers found 16 horses with lameness that could not be pinpointed. All 16 horses showed multiple sites of increased radiopharmaceutical uptake (or "hot spots") on scintigraphic images, which indicates increased bone activity (such as bone remodeling or healing after a fracture).

"The horses all have similar clinical symptoms and present with what we think are differing stages of the same disease," said Jonathan Anderson, BVM&S, resident in equine surgery at the hospital and lead author on the study.
