What can we learn from those Amazing old Sharks ?

Currently a Greenland shark (Somniosus microcephalus) is good for 400 year lifetime. I would do an annual harbor swim of port Nuuk and consume Hákarl  (cured shark)  followed by a jigger of Brennivín known as (Black_Death) for just another 100 years added to my life. Any ideas of a better method will be worthy of support and consideration. "Cold can also activate antiaging genes that help an animal better fold proteins, get rid of DNA-damaging molecules, and even fight off infections more effectively, extending life span. The cold-activated molecules “are evolutionarily conserved” across the animal kingdom, and thus these pathways very likely exist in us and these sharks too"

How new data can substantially alter interpretations -- placoderm evolution

An article in Nature (PDF below) reports on the discovery of internal embryos in placoderm (armored fish) fossils. Besides being interesting, these otherwise mundane discoveries have the possibility to radically alter our interpretation of the origin and relationships of early vertebrates. Here's the "News and Views" editorial on the research article, which is more accessible to non-specialists than the original paper.
