A practitioner took a scab from someone with a mild case, made an incision in the skin of a healthy person, and infected that person with the scab. Sheep-scab is a loathsome skin disease due to an acarian parasite.
BOSTON -- Call it cryonics for crustaceans. A Connecticut company says its frozen lobsters sometimes come back to life when thawed. Trufresh began freezing lobsters with a technique it used for years on salmon after an offhand suggestion by some workers. It found that some lobsters revived after their subzero sojourns.
They do have a rather unique feature in that lobsters do not die due to aging. They become stronger and more fertile with age due to the presence of enzyme telomerase (repairs DNA sequences). Thus lobsters continue to live until caught, injured or inflicted by disease.
