Lab-made bird flu details not to be revealed

Details of lab-made bird flu won't be revealed
WASHINGTON (AP) — The U.S. government paid scientists to figure out how the deadly bird flu virus might mutate to become a bigger threat to people — and two labs succeeded in creating new strains that are easier to spread.

On Tuesday, federal officials took the unprecedented step of asking those scientists not to publicize all the details of how they did it.

The worry: That this research with lots of potential to help the public might also be hijacked by would-be bioterrorists. The labs found that it appears easier than scientists had thought for the so-called H5N1 bird flu to evolve in a way that lets it spread easily between at least some mammals.

"It wasn't an easy decision," said Dr. Anthony Fauci, infectious diseases chief at the National Institutes of Health, which funded the original research.

The scary-sounding viruses are locked in high-security labs as researchers at the Erasmus University Medical Center in the Netherlands and the University of Wisconsin-Madison prepare to publish their findings in leading scientific journals. That's the way scientists share their work so that their colleagues can build on it, perhaps creating better ways to monitor bird flu in the wild, for example.

But biosecurity advisers to the government recommended that the journals Science and Nature publish only the general discoveries, not the full blueprint for these man-made strains. Tuesday, the government announced that it agreed and made the request.

‘Biggest’ dinosaur bones unveiled in US

Paleontologists have discovered what they claim are bones of the “biggest” dinosaur in the US.


A team from the Museum of Rockies in Montana State and the State Museum of Pennsylvania has described two gigantic vertebrae and a femur that it collected in New Mexico from 2003 to 2006 in a research report.

The bones belong to the sauropod dinosaur Alamosaurus sanjuanensis: A long-necked plant eater related to Diplodocus which roamed what is now the southwestern region of the US and Mexico about 69 million years ago.

In their report, the palaeontologists have written how carrying the the vertebrae alone was a “killer” task taking up an entire day because they carried them 1.2 miles through 100- degree heat, a website reported.

Denver W Fowler at Montana State University, who led the team, said: “Alamosaurus has been known for some time, its remains were first described in 1922 from the Naashoibito beds of New Mexico.

“Since then, more bones have been discovered in New Mexico, Utah, some really nice material from Texas, and Mexico, including a few partial skeletons.”

He said the sheer size of the new bones had caught the researchers by surprise, who had believed that a fully grown Alamosaurus measured around 60 feet long and weighed about 30 tons.

The enormity of the new bones puts Alamosaurus in the same size league as other giant sauropods from South America, including Argentinosaurus which weighed about 70 tons, and is widely considered to be the biggest dinosaur of all.

Dr Fowler said: “Over the past 20 years, Argentinean and Brazilian paleontologists have been unearthing bigger and bigger dinosaurs, putting the rest of the world in the shade.

“However, our new finds not only show that Alamosaurus is newly recognised as the biggest dinosaur from North America, but also that it was right up there with the biggest South American species…”

He added: “We found a shed Tyrannosaurus tooth with another Alamosaurus neck bone that we were excavating. The Tyrannosaurus may have lost its tooth while feeding on an Alamosaurus carcass.”

Call to halt spread of feral cats in the US

‘This is a human-caused tragedy'November 2011: American Bird Conservancy (ABC) is calling on US mayors to stop the epidemic spread of feral cats that threaten national bird populations as well as scores of other wildlife.

Letters have been mailed to mayors of the fifty largest cities in the Unites States, urging they support responsible pet ownership and oppose Trap-Neuter-Release (TNR) programmes that promote the feeding of outdoor cats.

‘Cat overpopulation is a human-caused tragedy that affects the health and well-being of cats, our native wildlife, and the public,' says Darin Schroeder, Vice President for Conservation Advocacy for ABC in a letter to the mayors. ‘Numerous published, scientific studies have shown that trap, neuter, re-abandon programmes do not reduce feral cat populations and that outdoor cats, even well-fed ones, kill hundreds of millions of wild birds and other animals each year in the US, including endangered species. Birds that nest or feed on the ground are especially vulnerable to cat attacks.

'About as fair as shooting of fish in a barrel'‘The domestic cat is an extremely effective predator that has been introduced by modern man into an environment whose species have evolved few, if any natural cat defences. Non-native, well-fed, inoculated, healthy cats versus defenseless prey is about as fair in the world of nature as the proverbial shooting of fish in a barrel,' he said.

Studies indicate that there are 95 million outdoor and feral cats in the United States that kill at least 532 million birds, and possibly significantly more. Given the well-documented impacts of cat predation on wildlife, ABC urges the mayors to oppose TNR programmes and the outdoor feeding of cats as a feral cat management option.

Through the Cats Indoors! campaign, ABC and its many partners encourage people to keep their cats indoors, train them to go outside on a harness and leash, or build outdoor cat enclosures. Cats should be spayed or neutered before they can produce an unwanted litter, and should never be abandoned. Abandoning cats is illegal in many areas, is extremely cruel to cats, and is harmful to birds and other wildlife.

‘TNR is not humane to the cats or the wildlife. Free-roaming cats are in constant danger of being hit by cars, contracting diseases and parasites, or being attacked by other animals or people,' said Schroeder. ‘Colonies often become dumping grounds for unwanted pets, thus continuing the inhumane cycle.'

Panther tracks found

New Carlisle resident says he saw big cat in field; deputies on hunt.
NEW CARLISLE — Several footprints that apparently belong to a large exotic cat have been found in the area.
Resident Jeff Brown said his neighbor, Matt Cooper, called him Sunday morning saying he’d spotted what looked like a panther sunning itself in his hay field in the New Carlisle area.
“He called me and said, ‘I just shot at something out back. I think I might have hit it,’ ” Brown said.
Believing it to be a black panther, the two set out with Clark County sheriff deputies but could not find it. However, they did find several footprints authorities said looked like those of a large cat.
Sheriff Gene Kelly said after receiving reports of a panther in the Harrison Twp. area in Montgomery County, he believes it could be the same cat.
“It could have followed the river and come north,” he said. “We have alerted Miami County and Champaign County since this area borders those other counties.”
Brown said he’s sure it was a panther, about 4 feet in length. He tied a large piece of venison in a nearby tree, and when he checked back hours later, something had devoured it.
Deputies are following up, and Kelly said anyone who spots the animal should notify his office and not try to catch it.
Following the release of several exotic animals in Muskingham County that had to be put down by authorities, Kelly said he’d like to apprehend the animal “in the most humane way” possible.
“We would certainly like to capture this animal safely and make sure the community is safe as well,” Kelly said.

Polar bears not endangered, US confirms (via Dawn Holloway)

Environmental campaigners in the US have lost a battle to have the polar bear listed as an "endangered" species.

The US department of the interior has upheld a decision to classify the bear as "threatened" - a status that gives them less protection under the law.

The government said it did not find that polar bears were on the brink of extinction, needed to qualify for the status of "endangered".

Environmental campaigners have said they will challenge the decision.

'Anti-science decision'
Under the Endangered Species Act, the status of "endangered" requires the government to assess the impact of greenhouse gases on the bears' Arctic homelands.

When the government is considering permits for oil development in northern Alaska, it must include greenhouse gas emissions in its decision.

When the polar bear was listed as "threatened" by the administration of former US President George W Bush, officials invoked a special rule saying the Endangered Species Act could not be used to regulate greenhouse gas emissions.

So an "endangered" listing is a more powerful tool for limiting industrial activity that causes greenhouse gases.

The Centre for Biological Diversity - one of the groups trying to get the polar bear listed as "endangered" - said the ruling showed that the administration of US President Barack Obama was continuing to defend Bush-era "anti-science decisions".

It says polar bears face an 80% chance of extinction within 40 years and it will continue to challenge the US government in court.
