With a name like “Leatherback Turtle” you might think the sea turtles could stand up to just about anything the ocean can throw at them, and for more than a hundred million years, they have. But tough, long-lived critters though they are, the population of leatherbacks in the eastern Pacific Ocean has plummeted by over 90 percent in the last 20 years.
Like many species that migrate across a vast ocean, pinpointing all the possible causes of their decline is difficult and figuring out where conservationists might be able to intervene on their behalf is hugely challenging. But a major effort to tag and track leatherbacks that nest on the Pacific coast of Costa Rica has yielded unprecedented insight into their behavior. While most sea turtles, including other populations of leatherbacks, have widely varied dispersal patterns as they fan out across the ocean from the beaches where they nest, the leatherbacks from the beaches at Playa Grande have been found to consistently fo...

Repositioning cruises are not a new phenomenon, they’re just one of the best kept secrets in the cruising industry. Like the migrating birds, many cruise ships head for warmer climates in the Autumn months and return in the Spring. Some move south for the winter months and then sail back again for the summer months. Other cruise ships cross the Atlantic or the Pacific Ocean to "reposition" themselves in warmer weather. Just like most vacationers, these fleets of ships are seeking seaso... more

Every cell contains a tiny clock called a telomere, which shortens each time the cell divides. Short telomeres are linked to a range of human diseases, including HIV, osteoporosis, heart disease and aging. Previous studies show that an enzyme within the cell, called telomerase, keeps immune cells young by preserving their telomere length and ability to continue dividing.
UCLA scientists found that the stress hormone cortisol suppresses immune cells’ ability to activate their telomerase.... more
Bats are a remarkable evolutionary success story representing the second largest group of mammals, outnumbered only by rodents in number of species. Now, researchers of the Leibniz-Institute for Zoo and Wildlife Research in Berlin (Germany) and Boston University (U.S.A.) have discovered the place that harbours the highest number of bat species ever recorded. In a few ha* of rainforest in the Amazon basin of eastern Ecuador, the authors have found more than 100 species of bats.

Researchers at the University of Nebraska Medical Center (UNMC) in Omaha have assisted in a significant discovery – the understanding of a common mechanism of cancer initiation – that could result in better cancer assessment, prevention and detection.
“We have a novel approach to cancer. We know the initiating step,” said Ercole Cavalieri, Ph.D., of the University of Nebraska Medical Center. “We think prevention of cancer can be solved by eliminating this initiating step.”... more
