Sharks' typical causes of death involve interactions with humans or simply old age. One reason for that, according to the new study, may be that the great white's genetic code hides a balance of DNA opposites that make the overall genome stable. On one hand, the genome has a large proportion of "jumping genes": genes that make copies of themselves then insert themselves into various parts of the genome.

Shivji said scientists would expect these genes to make the genome more unstable because they break up DNA strands upon insertion, which raises the risk of errors and damage in the genetic code. Such genomic instability is associated with higher risk of cancers in humans, as well as other age-related illnesses like Alzheimer's. But it turns out that the shark genome balances these jumping genes with stabilizing genes involved in DNA repair, damage response, and damage tolerance.
So it appears that great white sharks have developed a way to keep their genomes stable despite their large bodies and long lifespans, Shivji said. While the idea that sharks are cancer-proof continues to circulate, the animals can get the disease. There have been 44 reported instances of cancerous lesions among 21 different types of chondrichthyes, a species class that contains sharks and sting rays.
Of those 44 reports, about a third were malignant, according to a study. That cancer myth is the basis for shark-cartilage pills, the sale of which continues to decimate shark populations worldwide. Great whites are now listed as "vulnerable to extinction" by the International Union for the Conservation of Nature. Shivji emphasized that eating shark products — like taking the cartilage pills or consuming shark fin soup — won't improve your own genes' abilities to resist cancer.
But he added that the shark genome could give scientists "information that could be useful for human biomedical applications," including ways to "fight cancer and age-related diseases, and improve wound healing treatments. Any treatments developed based on these findings are still far off, though — Stanhope told Wired that "it will take years of work. Aylin Woodward.

Eastern Conference. Sharks News. We did not get down when we lost several one-goal games. I am a strong believer in character and you find how much you have when you face adversity. I think with Joe, it gives the offense a wider margin for error. We were battling, but coming up just short. It is a credit to the others that they have picked up their game. We believe our best hockey is ahead of us. The tough part was we were beating ourselves.
You have to play 60 minutes and pay attention to detail. During that stretch, we were making mental mistakes that were costing us games. We went through it a couple of years ago where we lost our attention to detail and were losing one-goal games.
