Earth Changes
The future doctors were perplexed. First-year students in Stanford University's School of Medicine, their impressive GPAs and MCAT exam scores didn't matter to these dusty volunteers.
But the students quickly discovered that other skills did. Like patience. Persistence. Rapport. Over a single afternoon, their "patients'' - three horses at Menlo Park's Webb Ranch - started paying attention.
Dr Dave Smith and Dr Dave Suggett visited Curieuse Island as part of an ongoing study funded by Mitsubishi Corporation in conjunction with the Earthwatch Institute. They were joined by PhD student Seb Hennige as well as local Seychelles collaborators.
The island, which is managed by the Seychelles Centre of Marine Research and Technology-Marine Protected Areas (SCMRT-MPA), is home to over 200 giant tortoises but it was thought no coral reefs were present.
Dr Smith said: 'Diving revealed an extensive coral reef to the south of the island, at a depth which would not be visible to the occasional snorkeller.'
Mercury exposure is known to occur as a result of man-made pollution and natural events such as volcanic eruptions.
According to the lead author of this study, Krishna Das of the Université de Liège, Belgium, "Mercury is known to bioaccumulate and to magnify in marine mammals, which is a cause of great concern in terms of their general health. In particular, the immune system is known to be susceptible to long-term mercury exposure". In order to determine the scale of this problem, the authors carried out analysis of the blood mercury levels of harbour seals caught in the North Sea and tested the effects of MeHg in lab experiments.
The Geodynamic Institute of Athens says the quake occurred at 5:17 a.m Thursday near the coastal town of Xylokastro, about 60 miles west of Athens.
Greece is one of the world's most earthquake-prone countries.
Later Monday, Health Ministry spokeswoman Yelena Bayalinova said the death toll was 72.
According to the Meteorology & Geophysics Agency (BMG), the earthquake measured five on the Richter scale with an epicenter at 11.7 south latitude and 116 east longitude or 335 kilometers away on the southeast side of Nusadua, Bali.
According to the Kenya Red Cross Society, the incident in Eastern Province on Wednesday occurred around 6pm.

This finding, released by scientists at the ARC Centre of Excellence for Coral Reef Studies, has raised hopes for the ability of the world's corals to withstand the rigors of changing climates and human impacts, says lead author Zoe Richards.
"Coral reefs worldwide face a variety of marine and land-based threats and hundreds of corals are now on the red list of threatened species. It is often assumed that rare coral species face higher risks of extinction than common species because they have very small effective population sizes, which implies that they may have limited genetic diversity and high levels of inbreeding and therefore be unable to adapt to changing conditions," Zoe says.
