TED.COM: Tuna are ocean athletes — fast, far-ranging predators whose habits we’re just beginning to understand. Marine biologist Barbara Block fits tuna with tracking transponder tags that record unprecedented amounts of data about these gorgeous, threatened fish and the ocean habitats they move through.
”Maybe use live links from blue whales and white sharks. Make killer apps if you will. A lot of people are excited about when sharks actually went under the Golden Gate Bridge. Let’s connect the public to this activity right on their iPhones”. Barbara Blocks
Barbara Block takes a multidisciplinary approach to studying how large pelagic fish live and travel in the open ocean. Using novel electronic tags, Block and her team track large predators — tunas, billfish and sharks — on their ocean journeys. She also studies how and why muscle makes heat at a molecular level in fish.
Working out of Stanford‘s Hopkins Marine Station, Block and her colleagues run the Tuna Research and Conservation Center, a member of the Tagging of Pacific Predators (TOPP)program. Combining tracking data with physiological and genetic analyses, Block (a MacArthur ”genius” grant winner) is developing population and ecological models to help us understand these fishes’ roles in the ocean ecosystem — and perhaps learn to better manage these important food fish.
A study in the journal Nature Reviews Cancer points out cancer has become a more common disease because of modern lifestyle. Cancer have increased since the Industrial Revolution. In the past 200 years, specific cancers like scrotal cancer and Hodgkin’s disease have emerged.
”Rosalie David, professor at the University of Manchester in the United Kingdom and Michael Zimmerman, professor at Villanova University in Pennsylvania, explored the evidence of cancer in the fossil record of early humans, in ancient Egypt and in ancient Greece. They argue that modern carcinogens – such as tobacco and pollution – may have contributed to the apparent rise in cancer in the last several hundred years.”
”There are very few indications of cancer in early human remains, and possibilities that have been found have been disputed, the analysis said. In Egypt, out of hundreds of mummies only one case of cancer has been confirmed: Zimmerman’s experiments on modern mummified tissue suggest that mummification does not destroy evidence of the malignancy – he and colleagues found colorectal cancer in a mummy.”

Clint Eastwood explores death and the beyond through three stories with solid performances by Matt Damon and Cécile de France.
Death is the barrier we can’t get around, an eternal void burdening those among the living who yearn for those who are gone. What would it mean if we could communicate with the other side, or even just be sure it existed?
That is the theme of the haunting ”Hereafter,” the latest work from Clint Eastwood, which presents a trio of stories having to do with what might be on that far side and how it relates to the world we know.
Actually, it is three stories that are told, and ”Hereafter” begins by providing a wonderful sense of uncertainty, giving us the gift of not knowing where these tales are going and whether or not they will have things in common besides dealing with death and the beyond. Like the similarly affecting ”Never Let Me Go,” ”Hereafter” is best approached with as little specific information as possible.
