A hormone that governs sleep and jet lag in humans may also drive the mass migration of plankton in the ocean, scientists have found. The molecule in question, melatonin, is essential to maintain our daily rhythm, and scientists have now discovered that it governs the nightly migration of a plankton species from the surface to deeper waters. The findings indicate that melatonin’s role in controlling daily rhythms probably evolved early in the history of animals, and hold hints to how our sleep patterns may have evolved.

We Don't Need No Stinking Papers
Commentary by Captain Paul Watson
I have been operating Sea Shepherd ships since 1978 and prior to that with Greenpeace vessels since 1971. And prior to that I served in the Canadian Coast Guard, onboard the Canadian Pacific Steamship Princess Margarite, and in the Norwegian and Swedish merchant marine. I have served as Captain on over 300 voyages undertaken, including trans oceanic voyages in some of the most hostile waters in the world. I have never put a ship aground nor lost a crewmember. Not once have I had to call for a rescue from any Coast Guard. Our ships have transited the Panama, Suez, and Kiel Canals and the Straits of Magellan, the Labrador Front, the Bering Sea and the Inside passage of Alaska. We have weathered storms and navigated through heavy ice conditions without mishap. I also set a record for the furthest point south reached by any ship.
And yet I constantly still hear criticisms that our ships are not run professionally, meaning our crew and I do not have the proper papers. And it is true we don't have the proper commercial papers that they continuously allude to for the simple reason that our vessels are not commercial ships. Our vessels are registered as non-commercial yachts and therefore our officers are legally qualified to hold their positions. Some who do have commercial papers do not declare them because holding a ticket also makes you subject to disciplinary action by the nation that issued the papers if they don’t like what you are doing – like harassing poachers and illegal Japanese whalers.
If I was not properly qualified to captain any of my ships I would not be allowed to get clearance into and out of foreign ports.
What I really find amusing is when some so called "captain" of a small coastal fishing boat berates me for not being a real captain because of what I do - which is defend life in the sea. They see legitimacy only where profits are being made and marine life is being exploited.
I doubt there are many fishermen in the world that have my experience, especially in ice- navigation and deep-sea voyages. So their criticisms are always taken with a grain of salt because they have absolutely no idea of what we do and how we do it, where we go and how we operate.
Our officers and crew have done amazing work over the years and we are proud of the fact that we have never lost a crewmember nor has any crewmember suffered any serious injuries. We have had over three thousand volunteers participate as crew over the years.
The Japanese whaling fleet has a fully licensed professional commercial crew and yet they have had two serious onboard fires, three deaths and numerous serious injuries.
The Exxon Valdez was operated by professionally licensed officers. And the attached clip of a recent collision between two container ships in the Suez Canal shows quite clearly that the mere possession of a piece of paper does not guarantee competence.
Last week the U.S. Coast Guard collided with a fishing vessel off Puerto Rico (ironically named the Sea Shepherd). A few years ago the Canadian Coast Guard towing a sealing boat flipped it and killed the fishermen onboard.
And then there is the case of the captain of the Concordia, that hit the rocks in Italy killing 32 people. You can't get better professional papers than being a captain of a passenger liner.
Sea Shepherd collides with vessels when we intend to collide with vessels and that is only when we have to stop their illegal activities. And we have done so without causing a single injury.
In light of so many numerous examples of disasters at sea involving officers with professional papers and the fact that Sea Shepherd has experienced zero casualties in nearly four decades of operations it is simply a sign of an ignorant bias that such accusations are made about Sea Shepherd officers and crew.
Would anyone say that the captains of the Colombo Express or the Maersk Tanjong are not competent seaman? No, because they have commercial papers.
So in answer to anyone who demands to know why we, and I don't have professionally issued licenses, the answers are 1. Not required and 2. Having such papers are not a guarantee of skill and experience 3. Having such papers would restrict our effectiveness and 4. A piece of paper issued by a government is not a guarantee of competence.
My preference is for experience and a passion for the job.
GRAND BRUIT, Newfoundland -- This old fishing port is a welcoming refuge for Atlantic sailors to tuck into on Newfoundland's rocky, fog-draped south coast -- except that it is empty of people today as if a plague had swept through it.

Marian Locksley's insight:
The answer given could not have been more clear:
It appears that some will heal, and some will scar. It seems obvious that an animal with a scar has survived the injury that caused the scar. A similar question applies to the renal lesions, which if severe and extensive, may be associated with renal failure. It seems plausible that in some cases these types of injuries will cause delayed mortality.
In short, from the drive process itself to capture, confinement and isolation, cetaceans suffer terribly, both psychologically and physically. Even when released, the scars that remain and the damage endured, can kill.
