Extraordinary Number of unique species discovered in Caribbean
..., bordered by Cuba, the Bahamas and Florida; and a stretch in the southern Caribbean that follows the coastlines of Colombia, Venezuela, Guyana, Suriname and the Netherlands Antilles. Scientists were also surprised to find that many unique species live at depths far greater than previously imagined, making t......the researchers applied a precisely known force to stretch the molecule. However, measuring the torsional stiffness of the molecule proved far more difficult. "For almost seven years, I couldn't convince any graduate student or postdoc to do these experiments," said Bustamante.
