Frankenstein's Cat: Biotechnology, Strange Creatures, and Us

What does genetically engineering animals—glowing fish, frozen zoos—mean?
Published on November 12, 2013 by Marc Bekoff, Ph.D. in Animal Emotions

I finally got around to reading a book with the catchy title, Frankenstein's Cat: Cuddling Up to Biotech's Brave New Beasts, by journalist Emily Anthes, and I'm sorry I let it sit on my cluttered desk for as long as I did. Highly-acclaimed, packed with a lot of information, very well-referenced, and an easy read, this book made me think hard and deep about our relationships with other animals (the focus of the field of anthrozoology) and just what is okay and what is not.

Some of the examples about which Ms. Anthes writes include cloning endangered and other species, creating frozen zoos, using prosthetics to help injured animals, supplementing their natural senses, and engineering mutant animals and glowing cats...

Small Islands Demand U.N. Protection

By Thalif Deen

UNITED NATIONS, Nov 11 2013 (IPS) - Threatened by rising seas, some of the world’s small island developing states (SIDS) are demanding that the U.N.’s new set of Sustainable Development Goals place a high priority on the protection of oceans and marine resources.

A growing number of SIDS, including Papua New Guinea, Samoa, the Maldives, Tonga, Nauru and Kiribati, are making a strong case for a stand-alone goal for the protection of oceans in the post-2015 development agenda known as the SDGs, which is currently under discussion.


Hassan Hussain Shihab, first secretary of the Maldives diplomatic mission to the U.N., told IPS that oceans are a priority for the Indian Ocean island nation, whose 339,000 citizens are threatened by sea-level rise.

“The establishment of an SDG dedicated to oceans is critical to Maldives as the oceans are our source of life, livelihood and the identity of the people,” he said.

Covering more than 70 percent of our planet’s surface, he said, oceans play a key role in supporting life on earth.......

The mollusc was born in  1499 contemporary of discovery of America and Martin Luther’s Reformation.

World’s oldest animal is 507 years old

It’s time to rewrite the record books. New accurate dating shows that the world’s oldest animal was 507 years old when it died in 2006. That’s more than 100 years older than previously thought.

In autumn 2006 a team of researchers went on an expedition to Iceland, where they discovered something that made the headlines across the world. The discovery even made it into the Guinness Book of World Records.

One of the Arctica islandica bivalve molluscs, also known as ocean quahogs, that the researchers picked up from the Icelandic seabed turned out to be around 405 years old, and thus the world’s oldest animal.

However, after taking a closer look at the old mollusc using more refined methods, the researchers found that the animal is actually 100 years older than they thought. The new estimate says that the mollusc is actually 507 years old:

“We got it wrong the first time and maybe we were a bit hastingly publishing our findings back then. But we are absolutely certain that we’ve got the right age now,” ocean scientist Paul Butler, who researches into the A. islandica at Bangor University in Wales, tells ScienceNordic...

Marine Debris: Microplastics – from facial scrub to the Great Lakes

Microplastics are in the Great Lakes – where do they come from and are they a problem?

In the Great Lakes, marine debris affects the beauty of our environment, is a health and safety hazard, threatens our wildlife and natural resources, and comes at a significant economic cost. From a beach covered in trash to an animal entangled in fishing line, marine debris is a problem we can’t ignore. This article focuses on microplastics, a little—and little known—type of marine debris.

Microplastics are tiny bits of plastic that often originate from beach litter, or even consumer face scrubs, that are beginning to concern scientists. In the summer of 2012, Great Lakes research scientists sampling Lakes Erie, Huron and Superior were surprised to find tiny plastic particles suspended in the water. Although they knew about microplastics, what surprised them was the small size of the plastic Microplastics image from NOAA.particles – less than one millimeter in diameter. In the Great Lakes samples, approximately 85% of the plastic debris found was microplastics.

Often, large pieces of plastic are gradually broken down into smaller and smaller fragments by weathering and abrasion until they become microplastics.  Other sources of microplastics include industrial pre-production plastic pellets and polyethylene bead exfoliants from personal care products. While the percentage of microplastics found in the Great Lakes samples was greater than that typical of ocean samples, scientists are concerned that results from ocean studies on microplastics apply to the Great Lakes....

The case of the mysterious seafood



An unknown percentage of the fish we eat isn't what's it's purported to be – FAO meeting explores how forensic techniques could help address the problem



The first victim was a Caucasian male in his late 30s. He popped down to the pub for lunch and ordered fish and chips. As he enjoyed his meal alongside a pint, he thought to himself that he'd never tasted haddock so fresh. But he was wrong. What he was eating wasn't haddock at all.

The second victim was a young Japanese woman in her early twenties. On a business trip to the U.S., she ordered tuna sashimi for lunch. It seemed fishy to her—and she was dead right.
The third was a South African fisherman we'll call "Nate." He never ate a thing, but as he plied the waters of the new fishery he'd recently started working, elsewhere poachers harvested protected spiny lobster and exported them with false documents—further damaging recovering fishing grounds Nate hoped to one day fish again.

Seafood identity theft?

In each of these three hypothetical cases the culprit was mistaken or misrepresented identity—of seafood.

"Identifying unprocessed fish is usually fairly easy," says Michele Kuruc of FAO's Fisheries and Aquaculture Department. "But today seafood is transported far abroad, to places where it may not be well known. Plus, as the industry has globalized, it is common that fish products are processed on floating factories before they come to shore. What inspectors see often doesn't look much like a fish in the wild."
In some instances, accurately identifying fish may be beyond the abilities of inspectors. Innocent clerical errors can end up turning one type of fish into another.
Or unscrupulous fishers and traders game the system to avoid restrictions or taxes.
According to Kuruc, those involved in illegal, unreported and unregulated (IUU) fishing use many methods to conceal their illegal activities and get their ill-gotten goods to market. "Fraudulent product substitution and use of false labels and documentation are frequently employed to transport and market products illicitly," she says.

The result? An unknown percentage of seafood on the shelves simply isn't what's it's purported to be.

Big stakes

This is a problem. Today's more conscious consumers are aware of the multiple health benefits of eating seafood—but are also keen to be sure they're eating fish that has been caught or farmed responsibly and is safe to eat.

And there's much more at stake.

In recent years a number of major food retailers have committed to stocking only seafood certified as sustainable. As of January 1, 2010, the world's biggest seafood market, the European Union, has put in place regulations aimed at blocking imports of fish not harvested legally.

With 110 million tonnes of seafood consumed globally per year, international trade in fish is valued at a record high of $86 billion annually and is a major source of employment and government revenue for developing countries, where many of the fishing grounds that feed the first world are found.

Additionally, concerns about the wellbeing of many fish stocks necessitates diligent oversight of what fish are being taken and where.

Forensic science can help

Forensic technologies based on genetics and chemistry are already being used by some countries to monitor and control trade in produce, animals and timber. So FAO recently convened a workshop of experts, inspectors, law enforcement officials, scientists and academics to discuss how they might be more widely deployed in fisheries enforcement.

"We're interested in promoting wider use of available forensic techniques, in particular by developing countries, Kuruc says."Some countries have successfully used various forensic methods in investigations and court cases, but many fisheries monitoring, control and surveillance personnel still remain unaware of their existence."

DNA analysis can reveal the species of a suspect white fillet. Chemical tests on fish earbones reveal absorbed nutrients and pinpoint the region where they were caught.

"We need to push the envelope, because we can be sure that those involved in IUU fishing are doing so," Kuruc added. "One workshop participant related how a group convicted of illegally trading abalone confessed that they learned techniques for destroying evidence by watching CSI: Miami."

In addition to surveying the state of the art and brainstorming how forensics might be used in fisheries and identifying needs—especially for capacity building in developing countries—the meeting also looked at best practices in handling evidence, how inspectors should be trained, and identifying laboratories capable of handling testing. (In many cases, labs in developing countries currently testing for food quality could be upgraded to conduct forensic work.)

The group also agreed to operate as an ad hoc FAO reference network that can be tapped by authorities around the world for guidance and advice.

"Fish can be properly identified if samples are handled properly, get to the right labs, and checked using forensic techniques," said Kuruc. "So the idea is to help countries that don't have such facilities and know-how access so them, so they can identify and prosecute cases of malfeasance."

Greenpeace vs. Russia: the tip of the iceberg?

News tips:

please read thisinteresting article posted by Irene Quaile on www.dw.de/greenpeace

Moscow rejects the authority of an international tribunal hearing an appeal for the release of the "Arctic 30" Greenpeace activists detained in Russia. Meanwhile, it's business as usual in the race for Arctic oil.

Some 13 percent of the world's remaining undiscovered oil reserves, 30 percent of its gas are estimated to be in the Arctic. The higher the price of energy, the faster the ice melts, the greater the international interest in a region becoming increasingly accessible as the world continues to warm. At the same time concern is growing amongst those who see development as a threat to the sensitive environment of the "High North" - and an increasing risk for the global climate: the burning of more fossil fuels would further intensify global change by producing more CO2 emissions.

The harsh nature of Russia's reaction to the Greenpeace protest at the Prirazlomnaya oil rig in the Arctic demonstrates how important the region has become for the government in Moscow. Thirty of the activists and accompanying journalists have been held in jail in Russia since the Greenpeace ship "Arctic Sunrise" was impounded by Russian security officers two months ago. Last week, the Russian Federation boycotted a hearing at the International Tribunal for the Law of the Sea (ITLOS), saying the court had no authority in the matter.
