Here are the highlights from the final day of the meeting: Carbon monoxide (CO) is not all that bad: Michael Tift, graduate student at Scripps Institute of Oceanography, described how the body naturally produces CO when red blood cells are broken down and CO can actually be protective against inflammation at low doses. His research was…

Secrets to longevity

A new article published in Physiological Reviews compared some remarkable similarities and differences between naked mole rats and humans. Both are relatively long-lived, highly social and have low natural selection pressures. But, this is about all they have in common. While humans are prone to developing age-related cancer, diabetes, heart disease and dementias, naked mole rats…

Amazing longevity of Greenland sharks

      A multi-national team of scientists sought to determine the age of Greenland sharks (Somniosus microcephalus). These animals grow rather slowly (about 1cm per year) and are the largest fish in the arctic (>500 cm long), but their longevity was not yet known. The team used radiocarbon dating of crystalline proteins found within the nuclei…

Great White Shark Longevity

Scientists have discovered that great white sharks (Carcharodon carcharias) actually live longer than previously thought (up to 23 years or so). Using radiocarbon age estimates, Dr. Hamady and colleagues at Woods Hole Oceanographic Institution determined the animals can live to the ripe-old-age of 70+ years. These findings mean that great white sharks, like humans, may…
