From Discovery News:

July 22, 2010 — Scientists have for the first time collected venom from octopuses captured from the waters of Antarctica.

In the process they have discovered four new octopus species and two new types of cephalopod venom.

Researchers hope the new venoms will lead to the development of drugs for pain management, fighting allergies and treating cancer.

The study was led by Bryan Fry of the University of Melbourne with researchers from the University of Hamburg and the Norwegian University of Technology and Science.

While venom has long been seen as a potential resource for drug development, scientists have only recently realized that the venom of cephalopods — octopuses, cuttlefish and squid — is unique.

Fry says venom enzyme activity is normally affected by temperature, but the enzymes in the Antarctic octopus venom somehow manage to stay active below zero.

“The venom of cephalopods living in the waters of the Antarctic has special adaptations allowing it to work in… sub zero temperatures. The next step is to work out what biochemical tricks they have used,” he said. “So far the analyses reveals that Antarctic octopus venom harbors a range of toxins, two of which had not previously been described.”

“Among the discoveries are new small proteins in the venom with very intriguing activities, which may be potentially useful in drug design,” he added.

The new study follows on from Fry’s revelation last year that all octopuses are venomous.

Since then, scientists have embarked on the huge task of collecting and studying these venoms to gain a greater understanding of their structure and how they work.

Fry’s team travelled to the Antarctic aboard the Australian Antarctic Division‘s flagship Aurora Australis, collecting 203 octopuses over more than six weeks.

They then genetically profiled each specimen to identify the species and collected venom to analyze in the lab.

“These are venoms that have never been studied before. There are minor differences which allow them to work and we still don’t know what those differences are,” Fry said. “So we’re comparing them to octopus venom with similar enzymes from other species like the tropical Blue-ringed octopus.”

ScienceDaily (Aug. 16, 2010) — While Arctic sea ice has been diminishing in recent decades, the Antarctic sea ice extent has been increasing slightly. Researchers from the Georgia Institute of Technology provide an explanation for the seeming paradox of increasing Antarctic sea ice in a warming climate: here.

As part of a study for the Census of Antarctic Marine Life (CAML), scientists from British Antarctic Survey (BAS) analysed sea-bed colonies of bryozoans from coastal and deep sea regions around the continent and from further afield. They found striking similarities in particular species of bryozoans living on the continental shelves of two seas – the Ross and Weddell – that are about 1,500 miles apart and separated by the West Antarctic Ice Sheet: here.

London zoo does not want nazi

Today, an invitation to the British Nazi Party Fuehrer Nick Griffin to attend a party at the royal palace was withdrawn.

On Twitter, it was suggested “Maybe Griffin can attend the Chimps Tea Party at London Zoo instead?”

London Zoo replied on Twitter: “We don’t want him!”

Indeed, it is very insulting to chimpanzees to compare them to a vile racist like Griffin.

As it also was insulting to chimps to compare them to warmonger George W. Bush.

Iraq war illegal, British deputy PM says

The Bronx Zoo Birders

July 21, 2010

At WCS’s Bronx Zoo, a group of WCS birders have been surveying the grounds for nesting wild birds. Their goal: to find out how the Zoo’s 265 acres, an important rest stop along the mid-Atlantic flyway and a green oasis in the midst of the big city, provides for breeding birds, and which species it attracts.

The birders are turning up some surprising finds, like wood ducks, warbling vireos, and black-crowned night herons. What’s even more surprising is where they’re finding them—singing in trees on the Bison Range, swimming through the once blighted Bronx River, even nesting in exhibit signage. Below, WCS publicist John Delaney leads a birding tour of the Zoo.

Just off the New York coastline lives an undersea wilderness. Sharks, sea turtles, dolphins, whales, seals, skates, and rays swim below the many flying shorebirds and seafaring ships of the eastern Atlantic. In all, more than 300 fish species feed, breed, and migrate through the New York Bight, which stretches between Montauk in northern Long Island to Cape May in southern New Jersey: here.

Amidst the Bronx’s miles of highways and railways, another force steadily rushes by: the Bronx River. Once plagued by pollution and neglect, today the New York waterway is home to alewife herring, night herons and egrets, muskrats, and even a lone beaver. The return of native wildlife is proof of the river’s improving health, and a testimony to community restoration efforts by WCS and other local groups: here.

Anti-Pinochet Chilean Corvalan dies

From British daily The Morning Star today:

Chilean communist Corvalan dies

Chile: Former Communist Party leader Luis Corvalan died on Wednesday at the age of 94.

The party was banned in Chile from 1948 to 1958 and Mr Corvalan spent those years as a prisoner.

He was again imprisoned by the Pinochet dictatorship from 1973 to 1976, when an international campaign led by the USSR helped to secure his freedom.

The Lenin Peace Prize winner was subsequently exiled to the USSR, where he led the CP in exile during the years of Pinochet’s rule.

He resigned as general secretary and returned to his homeland after the restoration of democracy in 1990.

Military officers convicted of human rights violations during the Pinochet dictatorship will not be pardoned after Chile’s president rejected a proposal by the Catholic church for elderly or sick prisoners to be freed: here.
