Meow! Claws out on Facebook Over Killer Cat Stats


"Good for them, go cats!"

"Sorry cats but you've gotta go."

"Do you get paid to write this?"

Well, nobody ever said cat lovers were mellow. But I was taken by surprise to see the number (and intensity) of comments on National Geographic's Facebook page and Daily News website after I wrote a story about a new study on the hunting habits of the domestic cat.

To recap: Cats stand accused of killing between 1.4 billion to 3.7 billion birds and 6.9 billion to 20.7 billion mammals in the continental United States each year.

There were hundreds of comments. One reader is "sick to death of watching my neighbors cats killing migratory songbirds."

"I don't think there should be an all encompassing feline genocide," said another, "but i feel something definitely needs to be done about feral populations."

Others found the study results far from newsworthy: "Yes, all of my cats are killers. That is why I brought them home in the first place" and "I love you National Geographic, but seriously... of course my cat is gonna kill some birds."

The study has sparked strong dialogue among bird and cat groups as well.

In a press release the American Bird Conservancy called the study a "wake-up call" and said "the carnage that outdoor cats inflict is staggering and can no longer be ignored or dismissed."

Alley Cat Allies and Best Friends Animal Society both questioned the study's estimates and suggested the researchers had ulterior motives. Alley Cat Allies, which calls itself "the only national advocacy organization dedicated to the protection and humane treatment of cats," said the study was a "veiled promotion by bird advocates to ramp up the mass killing of outdoor cats." The vice-chairman of Best Friends Animal Society, a group with projects throughout the U.S., claimed "the authors and the anti-free-roaming cat contingent want stray and feral cats to be rounded up and killed." He added that "scapegoating cats is a huge and, sadly, lucrative business."

The Humane Society of the United States also weighed in, reiterating their support for the "thousands of organizations and individuals who manage cat colonies through trap-neuter-return (TNR) programs," while adding that there would be no support in those quarters for a campaign to euthanize cats.

But maybe this was never about cat people and bird people after all. "Me thinks the dog lovers came up with those figures," suggested one National Geographic reader.

Boy Rescued in Ala. Standoff 'Laughing, Joking'













The 5-year-old boy held hostage in a nearly week-long standoff in Alabama is in good spirits and apparently unharmed after being reunited with his family at a hospital, according to his family and law enforcement officials.


The boy, identified only as Ethan, was rescued by the FBI Monday afternoon after they rushed the underground bunker where suspect Jimmy Lee Dykes, 65, was holding him. Dykes was killed in the raid and the boy was taken away from the bunker in an ambulance.


Ethan's thrilled relatives told "Good Morning America" today that he seemed "normal as a child could be" after what he went through and has been happily playing with his toy dinosaur.


"He's happy to be home," Ethan's great uncle Berlin Enfinger told "GMA." "He's very excited and he looks good."

"If I could, I would do cartwheels all the way down the road," Ethan's aunt Debra Cook said. "I was ecstatic. Everything just seemed like it was so much clearer. You know, we had all been walking around in a fog and everyone was just excited. There's no words to put how we felt and how relieved we were."


Cook said that Ethan has not yet told them anything about what happened in the bunker and they know very little about Dykes.


What the family does know is that they are overjoyed to have their "little buddy" back.

"He's a special child, 90 miles per hour all the time," Cook said. "[He's] a very, very loving child. When he walks in the room, he just lights it up."


Officials have remained tight-lipped about the raid, citing the ongoing investigation.


"I've been to the hospital," FBI Special Agent Steve Richardson told reporters Monday night. "I visited with Ethan. He is doing fine. He's laughing, joking, playing, eating, the things that you would expect a normal 5- to 6-year-old young man to do. He's very brave, he's very lucky, and the success story is that he's out safe and doing great."


Ethan is expected to be released from the hospital later today and head home where he will be greeted by birthday cards from his friends at school. Ethan will celebrate his 6th birthday Wednesday.


Officials were able to insert a high-tech camera into the 6-by-8-foot bunker to monitor Dykes' movements, and they became increasingly concerned that he might act out, a law enforcement source with direct knowledge told ABC News Monday. FBI special agents were positioned near the entrance of the bunker and used two explosions to gain entry at the door and neutralize Dykes.


Who Is Jimmy Lee Dykes?


"Within the past 24 hours, negotiations deteriorated and Mr. Dykes was observed holding a gun," the FBI's Richardson said. "At this point, the FBI agents, fearing the child was in imminent danger, entered the bunker and rescued the child."


Richardson said it "got tough to negotiate and communicate" with Dykes, but declined to give any specifics.


After the raid was complete, FBI bomb technicians checked the property for improvised explosive devices, the FBI said in a written statement Monday afternoon.


The FBI had created a mock bunker near the site and had been using it to train agents for different scenarios to get Ethan out, sources told ABC News.


Former FBI special agent and ABC News consultant Brad Garrett said rescue operators in this case had a delicate balance.


"You have to take into consideration if you're going to go in that room and go after Mr. Dykes, you have to be extremely careful because any sort of device you might use against him, could obviously harm Ethan because he's right there," he said.

Ice-age art hints at birth of modern mind



Sumit Paul-Choudhury, editor

Figurines from the Don river valley (Images: Kirstin Jennings)


The world’s oldest portrait, the world’s first fully carved sculpture, the world's oldest ceramic figure, the world’s earliest puppet - there’s no shortage of superlatives in the new exhibition of art from the ice age at the British Museum in London


But focus too closely on the exhibits’ record-breaking ages alone, and you might miss the broader point: these beautiful objects are the earliest evidence we have of humans who seem to have had minds like ours.






lionman.jpg

Consider, for example, the "lion man" found in 1939 in south-west Germany’s Stadel cave (pictured above). As the name suggests, this statue, standing 30 centimetres tall, harmoniously combines human and leonine features: the head is unmistakeably a lion’s, while the body and lower limbs are more human.


This is clearly the product of artistic creativity rather than a naturalistic drawing from life - suggesting that whoever carved it some 40,000 years ago had the capacity to express their imagination, as well as to replicate what they saw around them.


The temptation to speculate about what symbolic meaning the lion man might have had is, of course, irresistible. It was clearly valuable, taking around 400 hours and enormous skill to carve from a single piece of mammoth ivory.


The exhibition also includes a second, much smaller, feline figure found in another cave nearby, pointing to the idea that such imaginative objects might have cultural significance, perhaps as ritual objects within a shamanic belief system, rather than being isolated art objects.


Given what we know of modern traditions, that would make sense - but there is no hard evidence that anything resembling those traditions existed in Europe during the ice age.


Almost every object on show invites similarly thought-provoking consideration. Thumb-sized figurines from settlements along Russia's Don river (top) seem to present a woman's perception of her own pregnant body in an age before mirrors: no face, bowed head, the shelf of the bosom, the protrusion of the hips and buttock muscles and the swell of the belly.


Were they carved by the women themselves, perhaps as protective talismans for themselves or their unborn children? And if so, what are we to make of those that were apparently deliberately destroyed subsequently?


Only a few of the animal models found at the Czech site of Dolní Věstonice are intact. The rest had shattered into thousands of clay fragments when they were heated while still wet. This must also have been deliberate: was the dramatic shattering part of a rite?


A tiny relief of a human figure with upraised arms invites interpretation as a celebrant or worshipper. Was he or she participating in a ceremony to promote social cohesion during tough times - perhaps to the accompaniment of music played on instruments such as the flute displayed nearby, which is precisely carved from a vulture's wing-bone?


Such interpretations deserve a healthy dose of caution, of course. The note accompanying an elegantly carved water bird (perhaps a cormorant) found near the smaller lion man drily reads: "This sculpture may be a spiritual symbol connecting the upper, middle and lower worlds of the cosmos reached by a bird that flies in the sky, moves on land and dives through water.


“Alternatively, it may be an image of a small meal and a bag of feathers."


In the total absence of documentary evidence, there is no way of telling which is correct: archaeological material might help clarify the utilitarian perspective, but it is far less helpful when it comes to discovering any symbolic value.


In any case, there is very little archaeological evidence on display at the British Museum. Curator Jill Cook says she was keen to avoid exhausting visitors with copious background material about the evolutionary and environmental contexts in which these objects were made.


Humans were capable of complex behaviour long before they reached Europe - as demonstrated by discoveries such as the 100,000-year old "artist's workshop" in South Africa's Blombos cave - but Cook thinks the explosion of art among Europeans 40,000 years ago may reflect changing social needs during the ice age.


When Homo sapiens first arrived in Europe some 45,000 years ago, "the living was initially probably reasonably easy", explains Cook. They would have found temperatures only about 5 °C lower than they are now, she says, and grassy prairies would have been well stocked with bison. As the human population grew, they would have had to find new ways of building, socialising and organising themselves.


“And as it turns desperately cold, around 40,000 years ago, suddenly we have all this art," she says.


That may have reflected the need to communicate and develop ideas - a need pressing enough for people to spend hundreds of hours creating objects that generally seem to have had little quotidian function.


"This is all about planning and preconceiving and organising and collaborating and compromising," suggests Cook, "and that is something art and music helps us do."


The dazzling array of objects on display, spanning tens of thousands of years, anticipate practically every modern artistic tradition. The first portrait, dating back 26,000 years, includes closely modelled details of its female subject's unusual physiognomy, perhaps the result of an injury or illness.


But nearby is an extraordinary figure of similar age whose facial features are utterly abstract, resembling a visor with a double slit in it.


picasso-inspiration.jpg

Another (above) has a body whose angular patterns anticipate Cubism by some 23,000 years: Picasso kept two copies of it in his studio. Elsewhere, there are doll-like models of women with stylised faces, and female forms streamlined into little more than slender, strategically curved lines.


movement.jpg

Representations of animals, too, come in all forms, from incredibly realistic illustrations scratched onto stone or ivory, to elegantly minimal sculptures; there are even carvings designed to create the illusion of movement when viewed from different angles or rotated (above) - a form of prehistoric animation.


The masterpieces in the latter part of the show include - and sometimes combine - both precisely observed, superbly rendered naturalism, and more abstract work that is still beautiful, but much harder to interpret.


tusks.jpg

"The brain likes to tease us," says Cook. "We don't just represent things with great realism and naturalism, we like to break things down into patterns. That sparks your imagination, and makes you curious and questioning.


“What’s so spectacular about the modern brain, and the mind that it powers, is that it doesn't just make everything simple, it pushes us to new ideas and new thoughts."


After tens of thousands of years, the objects displayed in this extraordinary exhibition still have the power to do just that.

In video message, Malala says she's 'getting better'






LONDON: Malala Yousafzai, the Pakistani schoolgirl shot in the head by the Taliban for campaigning for girls' education, said she was "getting better day by day" in her first public statement released Monday.

The 15-year-old said she had been given a "second life" to campaign for girls to have the right to go to school, in a video statement recorded before she underwent surgery to repair her skull at a hospital in Britain on Saturday.

"Today you can see that I am alive. I can speak, I can see you, I can see everyone and I am getting better day by day," she said.

She spoke clearly in English, but displayed a lack of movement on the left side of her face.

She said: "It's just because of the prayers of people. Because all people -- men, women, children -- all of them have prayed for me.

"And because of all these prayers God has given me this new life -- a second life. And I want to serve. I want to serve the people. I want every girl, every child, to be educated. For that reason, we have organised the Malala Fund."

The Malala Fund is a charity set up in late 2012 to promote education for girls.

In the video, Malala is wearing a headscarf and flicking through some of the cards sent to her by wellwishers. She also recorded a message in Urdu.

Malala was shot at point-blank range by a Taliban gunman as her school bus travelled through Pakistan's Swat Valley on October 9, in an attack that drew worldwide condemnation.

Doctors say the bullet grazed Malala's brain and travelled through her head and neck before lodging in her left shoulder.

Surgeons in Pakistan saved her life with an operation to relieve the pressure on her brain before she was flown to Britain to be treated at Queen Elizabeth Hospital in Birmingham, central England.

The hospital has extensive experience of treating gunshot wounds suffered by British soldiers in Afghanistan.

In the surgery this weekend, Malala had a custom-made piece of titanium fitted to replace the missing part of her skull and surgeons also inserted an implant to help restore her hearing in her left ear.

Malala first rose to prominence aged 11 with a blog for the BBC's Urdu-language service charting her life under the Taliban.

Since her attempted murder, millions of people have signed petitions supporting her cause, and she has been nominated for this year's Nobel Peace Prize.

Former British prime minister Gordon Brown, a UN special envoy for education, has also taken up her cause.

The hospital's medical director Dave Rosser said on Monday that Malala was doing "very well" after spending about five hours in surgery and praised her for continuing to speak out for her cause.

Neurosurgeon Anwen White said that Malala did not need any more operations, would now continue with her rehabilitation and "hopefully she'll be discharged fairly soon."

Asked if there was any damage to Malala's brain, White said: "She hasn't got any long-lasting cognitive problems. There was a brain injury at the time of the wound but she's healing very well."

Before the latest operation Malala had left the hospital and had been staying with her parents and siblings who have joined her in Britain.

Her father has been given a job as education attache at Pakistan's consulate in Birmingham, a city with a large Pakistani community.

Angry Birds? "Shy" Sparrows Show Aggression With Wings


In the hugely popular video game Angry Birds, frustrated victims of egg theft vent their wrath by turning themselves into living bombs and blowing up their piggie tormentors. Of course, the successively more difficult levels of the game make things a little more complicated than that, as the millions who've been hooked know all too well.

Real-life birds don't have quite that kind of firepower, but, as I discovered as I researched my National Geographic book Angry Birds: 50 True Stories of the Fed Up, Feathered, and Furious, they've evolved an amazing array of ways to display their ire. Mockingbirds dive-bombing intruders, bellbirds ringing their nests with paralyzed poisonous caterpillars, eagles attacking hang gliders, frigatebirds pirating food from weaker birds—the variations of avian aggression seem endless.

And you probably don't even want to hear about baby fulmars, who projectile-vomit oily gunk to defend themselves against predators. (What's that bird? See National Geographic's Backyard Birding guide.)

Keep Your Eye on the Sparrow's Wing

Birds don't have to be big and powerful to show anger. Even sparrows—small, shy, brownish birds that tend to skulk in the underbrush—turn into mini-Hulks when breeding season comes around.

The swamp sparrow, a species found in wetlands through much of eastern North America, performs an odd display called the wing wave. Raising and quivering one wing at a time, the sparrow seems to be bidding good-bye to a friend, or maybe trying to dry its deodorant.

A team of scientists led by Duke University's Rindy Anderson, a specialist in animal communication, decided to look into the swamp sparrow's wing wave. "On a basic level, we wanted to know: Is wing-waving a communications signal?" Anderson said. "And if so, what information is being communicated? Our hunch was that wing-waving behavior, which is often paired with singing of various kinds, was playing some role in male-male aggressive signaling." (Find out why animals are smarter than you think.)

In simple terms, wing-waving may be the bird's way of saying, "Bring it on, buddy"—the equivalent of a stare-down in a biker bar.

Enter the Robo-bird

Many birds use song to claim a nesting territory, but it was difficult to test whether wing-waving was truly part of the male sparrow's homeland defense. As reported in the journal Behavioral Ecology and Sociobiology, Anderson's team came up with a clever experiment. They put a tiny mechanism inside a stuffed swamp sparrow so the taxidermied bird could mimic the wing wave, then placed the "robo-bird" in territories of nesting swamp sparrows. While playing a recorded song, they watched real birds' responses to the robo-bird in three modes: motionless, turning from side to side (to test whether simple movement had an affect), and wing-waving.

"It turned out the real birds were significantly more aggressive to the wing-waving robot than they were to either the motionless robot or the turning robot," Anderson said. "The intruder's wing wave might be signaling aggressive intentions, in the sense that it's signaling, 'I am here, and I am prepared to fight.' And the other bird then has to decide what they're going to do about it."

The Studs and the Wimps

Anderson found that individual birds varied in how aggressively they approached and attacked the robot. "You have wimps and you have studs and everybody in between," she says. She was surprised, though, that wing-waving reaction to the intruder didn't vary for individual birds; each male waved its wings a certain number of times that remained consistent no matter the robo-bird's behavior.

"I expected that there would be more wing-waving by the live birds in response to the wing-waving robot than in response to the other robots, but that didn't happen," Anderson says. "The birds were consistent in their own signaling behavior regardless of what the intruder was doing." Because actual fights can cause injury or even death, each male seems to have its own level of attempted visual intimidation through wing-waving before attacking a rival. No matter the provocation, studs stay studly and wimps stay wimpy.

There's still more to learn about the swamp sparrow's wave, Anderson says. "Because wing-waves and song are almost always given together, we're still not clear about whether those two displays are redundant. If a bird sings and wing-waves at the same time, is it signaling the same thing by the two behaviors, or does the wing-waving signal something different?"

Bug protects itself by turning its environment to gold









































Mythical King Midas was ultimately doomed because everything he touched turned to gold. Now, the reverse has been found in bacteria that owe their survival to a natural Midas touch.












Delftia acidovorans lives in sticky biofilms that form on top of gold deposits, but exposure to dissolved gold ions can kill it. That's because although metallic gold is unreactive, the ions are toxic.












To protect itself, the bacterium has evolved a chemical that detoxifies gold ions by turning them into harmless gold nanoparticles. These accumulate safely outside the bacterial cells.












"This could have potential for gold extraction," says Nathan Magarvey of McMaster University in Hamilton, Ontario, who led the team that uncovered the bugs' protective trick. "You could use the bug, or the molecules they secrete."












He says the discovery could be used to dissolve gold out of water carrying it, or to design sensors that would identify gold-rich streams and rivers.












The protective chemical is a protein dubbed delftibactin A. The bugs secrete it into the surroundings when they sense gold ions, and it chemically changes the ions into particles of gold 25 to 50 nanometres across. The particles accumulate wherever the bugs grow, creating patches of gold.











Deep purple gold













But don't go scanning streams for golden shimmers: the nanoparticle patches do not reflect light in the same way as bigger chunks of the metal – giving them a deep purple colour.












When Magarvey deliberately snipped out the gene that makes delftibactin A, the bacteria died or struggled to survive exposure to gold chloride. Adding the protein to the petri dish rescued them.











The bacterium Magarvey investigated is one of two species that thrive on gold, both identified a decade or so ago by Frank Reith of the University of Adelaide in Australia. In 2009 Reith discovered that the other species, Cupriavidus metallidurans, survives using the slightly riskier strategy of changing gold ions into gold inside its cells.













"If delftibactin is selective for gold, it might be useful for gold recovery or as a biosensor," says Reith. "But how much dissolved gold is out there is difficult to say."

S-League go topless to promote 2013 season






SINGAPORE: Topless - that's how some S-League players were spotted at Orchard Road on Sunday.

The bare-bodied manoeuvre was a publicity stunt for the 2013 S-League season, which kicks off later this month.

The 10 players were not completely naked from the waist up though; their bodies were painted in their respective team strip.

Joining them was S-League CEO Lim Chin, who was game enough to market the league in the bold and rather bare fashion.

Accompanied by fans, the entourage walked down Singapore's famous shopping district distributing flyers.

The approach was a departure from the usual carnivals held by organisers to connect with potential supporters, giving new meaning to 'meeting your heroes in the flesh'.

"I want the players to be involved ... We wanted to something to show… that we really want to reach out to the public, from the players right down to the kit man, to myself," said Mr Lim.

The 2013 season kicks off with the Charity Shield on 15 February, where defending champions Tampines Rovers will take on League Cup winners the Warriors at Jalan Besar Stadium.
