Obama Signs Order to Begin Sequester Cuts

President Obama and congressional leaders today failed to reach a breakthrough to avert a sweeping package of automatic spending cuts, setting into motion $85 billion of across-the-board belt-tightening that neither had wanted to see.

President Obama officially initiated the cuts with an order to agencies Friday evening.

He had met for just over an hour at the White House Friday morning with Republican leaders House Speaker John Boehner and Senate Minority Leader Mitch McConnell and his Democratic allies, House Minority Leader Nancy Pelosi, Senate Majority Leader Harry Reid and Vice President Joe Biden.

But the parties emerged from their first face-to-face meeting of the year resigned to see the cuts take hold at midnight.

"This is not a win for anybody," Obama lamented in a statement to reporters after the meeting. "This is a loss for the American people."

Officials have said the spending reductions immediately take effect Saturday but that the pain from reduced government services and furloughs of tens of thousands of federal employees would be felt gradually in the weeks ahead.

Sequester Countdown: The Reality of Budget Cuts Watch Video

Federal agencies, including Homeland Security, the Pentagon, Internal Revenue Service and the Department of Education, have all prepared to notify employees that they will have to take one unpaid day off per week through the end of the year.

The staffing trims could slow many government services, including airport screenings, air traffic control, and law enforcement investigations and prosecutions. Spending on education programs and health services for low-income families will also get clipped.

"It is absolutely true that this is not going to precipitate the crisis" that would have been caused by the so-called fiscal cliff, Obama said. "But people are going to be hurt. The economy will not grow as quickly as it would have. Unemployment will not go down as quickly as it would have. And there are lives behind that. And it's real."

The sticking point in the debate over the automatic cuts -- known as sequester -- has remained the same between the parties for more than a year since the cuts were first proposed: whether to include more new tax revenue in a broad deficit reduction plan.

The White House insists there must be higher tax revenue, through elimination of tax loopholes and deductions that benefit wealthier Americans and corporations. Republicans seek an approach of spending cuts only, with an emphasis on entitlement programs. It's a deep divide that both sides have proven unable to bridge.

"This discussion about revenue, in my view, is over," Boehner told reporters after the meeting. "It's about taking on the spending problem here in Washington."

Boehner: No New Taxes to Avert Sequester

Boehner says any elimination of tax loopholes or deductions should be part of a broader tax code overhaul aimed at lowering rates overall, not to offset spending cuts in the sequester.

Obama countered today that he's willing to "take on the problem where it exists, on entitlements, and do some things that my own party doesn't like."

But he says Republicans must be willing to eliminate some tax loopholes as part of a deal.

"They refuse to budge on closing a single wasteful loophole to help reduce the deficit," Obama said. "We can and must replace these cuts with a more balanced approach that asks something from everybody."

Can anything more be done by either side to reach a middle ground?

The president today claimed he's done all he can. "I am not a dictator, I'm the president," Obama said.

Mystery ring of radiation briefly encircled Earth

What were you doing last September? The charged particles that dance around Earth were busy. Unbeknown to most earthlings, a previously unseen ring of radiation encircled our planet for nearly the whole month – before being destroyed by a powerful interplanetary shock wave.

We already knew that two, persistent belts of charged particles, called the Van Allen radiation belts, encircle Earth. The discovery of a third, middle ring by NASA's twin Van Allen probes, launched in August 2012, suggests that these belts, which have puzzled scientists for over 50 years, are even stranger than we thought. Working out what caused the third ring to develop could help protect spacecraft from damaging doses of radiation.

Charged particles get trapped by Earth's magnetic field into two distinct regions, forming the belts. The inner belt, which extends from an altitude of 1600 to 12,900 kilometres, is fairly stable. But the outer belt, spanning altitudes ranging from 19,000 to 40,000 kilometres, can vary wildly. Over the course of minutes or hours, its electrons can be accelerated to close to the speed of light, and it can grow to 100 times its usual size.

Mystery acceleration

No one is sure what causes these "acceleration events", although it seems to have something to do with solar activity interacting with the Earths' magnetic field.

"That's one of the key things the probes are in place to understand," says Dan Baker of the University of Colorado, Boulder. "How does this cosmic accelerator, operating just a few thousand miles above our head, accelerate electrons to such extraordinarily high energies?"

When the Van Allen probes started taking data on 1 September 2012, one of these mysterious events was already under way. "We came in the middle of the movie there," Baker says. But otherwise, he says, "What we expected was what we saw when we first turned on: two distinct belts, separated."

That changed a day later when, to the team's surprise, an extra ring developed between the inner and outer ones. "We watched it develop right before our eyes," Baker says. The new, middle ring was relatively narrow, and its electrons had energies between 4 and 7.5 megaelectronvolts - about the same as in the outer Van Allen belt during an acceleration event.

Although the outer ring displayed its characteristic inconstancy, the new middle ring barely budged for nearly four weeks. Then a shock wave, probably linked to a burst of solar activity, wiped it out in less than an hour on 1 October.

Spacecraft malfunctions

It's not clear where the middle ring came from, Baker says, although it was probably related to the acceleration event. The electrons could have been stripped from the outer Van Allen belt, funnelled back towards the Earth and got trapped in the middle on the way, or they could have been energised from closer to Earth and shot up to higher altitudes.

Figuring out what happened could be important to protecting spacecraft from radiation damage, says Yuri Shprits of the University of California in Los Angeles, who was not involved in the observations but is crafting a theoretical explanation that he hopes to publish soon. "It truly presents us with a very important question, and very important puzzles," he says.

There were no specific spacecraft malfunctions during September that can be directly linked to the new belt, says Shprits. However satellite operators will want to know if such belts are common and if they pose more of a risk.

With no other examples of a transient belt caught so far, it's too soon to answer all those questions, Baker says. "We only have one in captivity," he says. "We're still trying to figure out exactly how it works."

Needy families on public assistance scheme to get higher payouts

SINGAPORE: From April, Public Assistance (PA) recipients can look forward to a higher level of assistance that is flexible and customised to their needs.

The Ministry of Social and Family Development (MSF) will enhance the PA scheme by providing additional assistance, other than a higher direct cash handout.

The change will mainly benefit those with special or once-off needs.

For example, additional assistance will be given to those who need healthcare and hygiene products such as adult diapers and nutritional milk supplements, or those who need once-off purchase or replacement of equipment such as a commode.

The ministry expects about one-third of existing PA households to benefit from the additional forms of assistance.

There are currently over 3,000 households on public assistance.

The cash assistance for all PA households will also be increased. The increase will range from S$50 per month for a one-person PA household to S$130 per month for a four-person PA household.

PA families with dependent children will continue to receive additional cash assistance of S$150 per child.

The ministry also added that the revision is part of the regular review of basic cash assistance rates to ensure that they are adequate to meet the needs of PA households.

Do Not Track privacy bill reintroduced in Senate

Senator Jay Rockefeller

A new bill intended to grant more privacy protections to Internet users was introduced today by U.S. Sen. Jay Rockefeller.

Dubbed "Do-Not-Track Online Act of 2013," the bill would make it law for all Web browsers, online companies, and app makers to give users a choice of opting out of being tracked online, according to The New York Times. Advertisers and data brokers commonly track users to collect information on sites visited, search queries, purchasing patterns, and more.

"The privacy of Americans is increasingly under assault as more and more of their daily lives are conducted online," Rockefeller told The New York Times.

The senator proposed a similar bill in 2011 but then dropped it after industry groups said they would voluntarily develop ways for users to opt out. However, the industry groups were unable to come to an agreement with consumer rights groups about how to create such mechanisms.

"Industry made a public pledge to develop do-not-track standards that will truly protect consumer privacy -- and it has failed to live up to that commitment," Rockefeller told the Times. "They have dragged their feet long enough."

According to The New York Times, these industry groups argue that tracking is necessary because it helps advertisers show users pertinent ads, which pay for the sites. Also, tracking is more or less anonymous -- since data trackers follow IP addresses rather than users directly; so, industry groups say, no significant information about users is revealed.

Several Web browsers and tech companies have already given users Do Not Track options. Google built Do Not Track support into its Chrome Web browser in February 2012; and Yahoo implemented a Do Not Track service across its entire global network last March. Mozilla, Microsoft, and AOL have also committed to working with Do Not Track technology.

However, without a law, browsers and companies aren't required to comply with user wishes to opt out. Therefore, Rockefeller has decided to push his new bill to Congress.

In addition to giving users an opt-out choice, the Do-Not-Track Online Act of 2013 would also allow the Federal Trade Commission to go after those companies that aren't complying with the law. The FTC would also be required to create the mechanisms that would let users say whether or not they want to be tracked.

Despite many attempts to introduce legislation, federal Internet privacy laws are scarce. The last major law to be passed that regulated online companies was 15 years ago with the Children's Online Privacy Protection Act.

Scarred Duckbill Dinosaur Escaped T. Rex Attack

A scar on the face of a duckbill dinosaur received after a close encounter with a Tyrannosaurus rex is the first clear case of a healed dinosaur wound, scientists say.

The finding, detailed in the current issue of the journal Cretaceous Research, also reveals that the healing properties of dinosaur skin were likely very similar to that of modern reptiles.

The lucky dinosaur was an adult Edmontosaurus annectens, a species of duckbill dinosaur that lived in what is today the Hell Creek region of South Dakota about 65 to 67 million years ago. (Explore a prehistoric time line.)

A teardrop-shaped patch of fossilized skin about 5 by 5 inches (12 by 14 centimeters) that was discovered with the creature's bones and is thought to have come from above its right eye, includes an oval-shaped section that is incongruous with the surrounding skin. (Related: "'Dinosaur Mummy' Found; Have Intact Skin, Tissue.")

Bruce Rothschild, a professor of medicine at the University of Kansas and Northeast Ohio Medical University, said the first time he laid eyes on it, it was "quite clear" to him that he was looking at an old wound.

"That was unequivocal," said Rothschild, who is a co-author of the new study.

A Terrible Attacker

The skull of the scarred Edmontosaurus also showed signs of trauma, and from the size and shape of the marks on the bone, Rothschild and fellow co-author Robert DePalma, a paleontologist at the Palm Beach Museum of Natural History in Florida, speculate the creature was attacked by a T. rex.

It's likely, though still unproven, that both the skin wound and the skull injury were sustained during the same attack, the scientists say. The wound "was large enough to have been a claw or a tooth," Rothschild said.

Rothschild and DePalma also compared the dinosaur wound to healed wounds on modern reptiles, including iguanas, and found the scar patterns to be nearly identical.

It isn't surprising that the wounds would be similar, said paleontologist David Burnham of the University of Kansas Biodiversity Institute, since dinosaurs and lizards are distant cousins.

"That's kind of what we would expect," said Burnham, who was not involved in the study. "It's what makes evolution work—that we can depend on this."

Dog-Eat-Dog

Phil Bell, a paleontologist with the Pipestone Creek Dinosaur Initiative in Canada who also was not involved in the research, called the Edmontosaurus fossil "a really nicely preserved animal with a very obvious scar."

He's not convinced, however, that it was caused by a predator attack. The size of the scar is relatively small, Bell said, and would also be consistent with the skin being pierced in some other accident such as a fall.

"But certainly the marks that you see on the skull, those are [more consistent] with Tyrannosaur-bitten bones," he added.

Prior to the discovery, scientists knew of one other case of a dinosaur wound. But in that instance, it was an unhealed wound that scientists think was inflicted by scavengers after the creature was already dead.

It's very likely that this particular Edmontosaurus wasn't the only dinosaur to sport scars, whether from battle wounds or accidents, Bell added.

"I would imagine just about every dinosaur walking around had similar scars," he said. (Read about "Extreme Dinosaurs" in National Geographic magazine.)

"Tigers and lions have scarred noses, and great white sharks have got dings on their noses and nips taken out of their fins. It's a dog-eat-dog world out there, and [Edmontosaurus was] unfortunately in the line of fire from some pretty big and nasty predators ... This one was just lucky to get away."

Mysterious Escape

Just how Edmontosaurus survived a T. rex attack is still unclear. "Escape from a T. rex is something that we wouldn't think would happen," Burnham said.

Duckbill dinosaurs, also known as Hadrosaurs, were not without defenses. Edmontosaurus, for example, grew up to 30 feet (9 meters) in length, and could swipe its hefty tail or kick its legs to fell predators.

Furthermore, they were fast. "Hadrosaurs like Edmontosaurus had very powerful [running] muscles, which would have made them difficult to catch once they'd taken flight," Bell said.

Duckbills were also herd animals, so maybe this one escaped with help from neighbors. Or perhaps the T. rex that attacked it was young. "There's something surrounding this case that we don't know yet," Burnham said.

Figuring out the details of the story is part of what makes paleontology exciting, he added. "We construct past lives. We can go back into a day in the life of this animal and talk about an attack and [about] it getting away. That's pretty cool."

Arias Recounts Each Moment of Stabbing, Slashing

Accused murderer Jodi Arias was forced to recount today each detail of how she killed her ex-boyfriend, Travis Alexander, including re-enacting how he allegedly tackled her when she shot him, leaving her crying in her hands on the witness stand.

During hours of dramatic cross-examination by prosecutor Juan Martinez, Arias bawled as he asked her about stabbing, slashing and shooting Alexander on June 4, 2008.

"You would acknowledge that Mr. Alexander was stabbed, and that the stabbing was with the knife, and it was after the shooting according to you, right?" Martinez said in rapid succession.

"Yes, I don't remember," Arias said, covering her face with her hands.

"Do you acknowledge the stab wounds, and we can count them together, were to the back of the head and the torso?" Martinez said, flashing a photo of Alexander's bloodied body onto the courtroom projector. " Do you want to take a look at the photo?"

Arias, burying her face in her hands and shutting her eyes on the stand, mumbled, "No."

Alexander's sisters, seated in the front row of the gallery, also looked away, crying.

Arias, 32, is accused of killing Alexander on June 4, 2008 out of jealousy. He was stabbed 27 times, his throat was slashed and he was shot in the head twice.

Arias claims she killed in self-defense after Alexander had become increasingly violent with her. She could face the death penalty if convicted.

Martinez also forced Arias to demonstrate in court today how she claims Alexander lunged at her "like a linebacker," causing her to fire the gun at him. The pair argued over how exactly Alexander was positioned, and Martinez pushed her to explain what she meant.

"He lunges at me like a linebacker," Arias said.

"Like a linebacker, what does that mean?" Martinez asked.

"He was low. It was almost like he dove," she said, and trying to explain it further, added, "He was like a linebacker is the only way I can describe it unless I get up to act it out which I'd rather not do."

Timeline of the Jodi Arias Trial

"Go ahead and do it," Martinez said. "Just stand. Go ahead."

Judge Sherry Stephens initially cleared the court as Arias demonstrated and then Martinez had her do it again after the jury and spectators were allowed back into the courtroom.

Standing and moving away from the witness box, Arias bent at the waist and spread out her arms and meekly made a slight lunging motion.

According to her testimony, Arias fired the gun as Alexander rushed at her, tackling her to the ground. She said she does not remember how she stabbed or slashed him.

It was a day of dramatics and anger as the prosecution pressed Arias on the details of the killing, with Martinez ending the afternoon of questioning by accusing Arias of lying throughout her direct testimony.

At one point Arias dissolved into tears, unable to answer pointed questions when shown a photo of Alexander's body lying crumpled in the bottom of the stall shower.

After a short pause, Martinez asked dryly, "Were you crying when you were shooting him?"

"I don't remember," Arias moaned.

"Were you crying when you stabbed him?" he said. "How about when you slashed his throat?"

"I don't remember, I don't know."

Martinez pressed on, "You're the one that did this right? And lied about all this right?"

"Yes."

"So then take a look at it," he barked.

Arias did not answer Martinez's question, crying into her hands instead. The judge, after a moment, called for the lunch recess to take a break from the testimony. Arias' attorney walked over and consoled her, telling her to "take a moment."

Until that moment, Arias had given vague answers to Martinez as he asked about the hours leading up to the murder. Arias, 32, has testified that she drove to Alexander's house on June 4, 2008, for a sexual liaison, that she had sex with Alexander and the pair took nude photos before an explosive confrontation ended with her killing him. She claims she doesn't remember stabbing Alexander, but insists it was in self-defense.

Martinez questioned her claims, asking exactly what they argued about and who encouraged whom to take the nude photos. He pointed out that Arias told Detective Esteban Flores of the Mesa police department that she had to convince Alexander to take the nude photos in the shower, but that she testified on the stand that Alexander had wanted them.

Quantum skyfall puts Einstein's gravity to the test

DIVIDING a falling cloud of frozen atoms sounds like an exotic weather experiment. In fact, it's the latest way to probe whether tiny objects obey Einstein's theory of general relativity, our leading explanation for gravity.

General relativity is based on the equivalence principle, which says that in free fall, all objects fall at the same rate, whatever their mass, provided the only force at work is gravity. That has been proven for large objects: legend has it that Galileo did it first by dropping various balls from the Tower of Pisa. Whether equivalence holds at quantum scales, where gravity's effects are not well understood, isn't clear. Figuring it out could help create a quantum theory of gravity, one of the biggest goals of modern physics.

Creating a quantum equivalent of Galileo's test isn't easy. In 2010 a team led by Ernst Rasel of the University of Hannover in Germany monitored a quantum object in free fall, by tossing a Bose-Einstein condensate (BEC) – a cloud of chilled atoms that behaves as a single quantum object and so is both particle and wave – down a 110-metre tall tower. Now they have split and recombined the wave – all before the BEC, made of rubidium atoms, reached the bottom. This produces an interference pattern that records the path of the falling atoms and can be used to calculate their acceleration (Physical Review Letters, doi.org/km6). The next step is to do the same experiment on a different kind of atom, with a different mass, to see if the equivalence principle holds.

The BEC can only be split for 100 milliseconds in the tower before hitting the bottom, so to allow tiny differences between the atom types to emerge, the work must be repeated in space, where the waves can be split for longer. By showing that a matter-wave can be split and recombined while falling, Rasel's result is a "major step" towards the space version, says Charles Wang of the University of Aberdeen, UK.

New SDPC mark for cigarettes from 1 March

SINGAPORE: From 1 March, cigarettes sold in Singapore which do not bear the new Singapore Duty-Paid Cigarette (SDPC) mark will be deemed duty-unpaid and illegal.

The new SDPC mark features a series of vertical bars around the cigarette stick.

The Singapore Customs said this allows enforcement officers and the public to easily differentiate duty-paid cigarettes from duty-unpaid or contraband cigarettes.

This measure will also enhance the effectiveness of the anti-contraband cigarette operations that Singapore Customs conducts across the island to curb the selling, buying and possession of contraband cigarettes.

To give manufacturers and retailers sufficient time to phase in the new SDPC mark, cigarettes bearing the new SDPC mark were allowed to be sold from 1 December 2012.

Travellers who bring in cigarettes from overseas for their own consumption are required to declare them at the Customs Red Channel for payment of duty and Goods and Services Tax (GST).

And they are advised to keep the receipt issued by Singapore Customs as proof of payment of duty and GST.

Those who buy, sell, deliver, store, keep, possess or deal with duty-unpaid goods face stiff penalties.

They could be fined up to 40 times the amount of duty evaded and jailed for up to six years.

Members of the public with information on smuggling activities or evasion of Customs duty or GST should contact Singapore Customs on its hotline 1800-2330000 or email customs_intelligence@customs.gov.sg.

Firefox and Tizen make a move for Android

Likely by Samsung's design, the Tizen OS looks reminiscent of Android.

(Credit:
CBS Interactive)

Alongside a myriad of new tablets and phones, Mobile World Congress 2013 also gave us our first real look at Mozilla's Firefox OS and the Samsung and Intel collaboration, Tizen OS.

While
Android might dominate the smartphone landscape today, it's only five years old. I can recall plenty of headlines in 2007 and 2008 that doubted whether there was room for yet another player in the space. At that time, RIM was a powerhouse, the iPhone was brand new, Palm's WebOS was in development, and Microsoft's Windows Mobile was slipping into obscurity.

My, how things have changed. Now the question is, it can happen again? Will
Firefox OS or Tizen OS impact Android or the smartphone landscape?

Cutting a piece of the smartphone pie
I predict that both will find success in developing markets and could even prove to be a bee in the Microsoft Windows Phone 8 bonnet. In fact, the definition of success could be interpreted differently for those involved. With smartphone activations rising all the time, even a small piece of the pie might be considered tasty.

I'm not entirely sure how Mozilla plans to monetize its open-source platform; Mozilla doesn't have search and mobile advertising to fall back on. Nevertheless, there are at least 18 handset makers and carriers who have pledged support for it. Really, who could fault any company for at least sampling the new goods?

There are already four such phones on the way -- the Alcatel One Touch Fire, the ZTE Open, the Geeksphone Keon, and the Geeksphone Peak -- and, I suspect, a handful more before the year is out. As of now, these devices are nowhere near as powerful as today's typical Android but that may not matter to the average consumer. We shouldn't expect much Firefox OS in the United States, though it's possible the bigger players are taking a "wait and see" approach.

LG also did a bit of hedging this week when it added its name to Mozilla's list of partners. LG even gave WebOS a new lease on life when it announced a licensing deal for the nearly-dead platform. Currently offering a number of Google TV sets, it's unclear how WebOS fits into the big scheme of things. Though I guess that it can't hurt to try new things every once in a while.

Alcatel's Firefox OS phone

Even so, I get the feeling that for now LG's bread is buttered by Google and that Firefox OS may be employed on devices released in secondary markets. Based on its diverse Mobile World Congress announcements, LG has a lot of Android momentum right now so I don't expect the company to change things up too much.

Samsung plays the field

Samsung, for its part, seems to be doing a little bit of everything these days. It introduced the Galaxy Note 8 in Barcelona, but it saved the reveal of the Galaxy S4 for an exclusive event on March 14. And though the company told CNET that it would pass on Firefox, it also said that it would be the first manufacturer to sell a Tizen phone come July. What about Bada, you ask? Well, a Korean news outlet said that Sammy would fold its own Bada OS into Tizen.

The first images of Tizen OS are reminiscent of Android, most likely due to Samsung. In fact, it wouldn't surprise me if future Galaxy experiences looked less like Android and more like Samsung. Should Samsung find success with the platform it may be possible to peel off a few Android users who have grown to use services such as Media Hub. In the big scheme of things, I imagine Samsung will create its own experience that looks the same on Android and Tizen.

It's too early in the game to forecast whether Tizen will impact its Android efforts, but whether Tizen makes it to the United States will make a big difference. While the platform has already drawn support from carriers around the globe, only Sprint has expressed interest for the U.S. market. And carriers aside, I'm more anxious to see which OEMs consider Tizen. It's hard to imagine a company like HTC, LG, or Sony, willing to use a platform created by a competitor.

Tizen OS gets early walkthrough in hands-on video

What's more, Samsung's new Knox is another signal that much attention is being paid to a broader consumer experience. Its bring-your-own-device (BYOD) solution would work well anyone who wants to want to use the same phone for work and personal use. Available for Android today, the feature might be available with other OSes like Tizen down the road. If that happens, Samsung would no doubt continue as one of Google's strongest Android partners, but the two companies may dance a little less frequently.

What's next?

Looking ahead, we may be in for more land grabs as hardware makers acquire software companies. We've seen this over the last few years with Apple, HTC, Samsung, and others. We've also seen jockeying from Amazon, Google, and other companies who scoop up services and apps. While some of these moves happen quietly and without much consequence, others are more overt and telling. One thing seems certain: nobody feels safe in this space. Rather, no one should feel safe.

In the short term, Firefox OS and Tizen will build a bit of steam; however, don't look for either to overtake RIM (especially following the launch of BlackBerry 10) or Windows Phone soon. And don't event think about a threat to iOS or Android. But then again, the growth of smartphone use in emerging markets is creating more competition. Android, after all, certainly surpassed the expectations of its early naysayers.

I am only too pleased that both of these new platforms are open-source as that should lead to more innovation. Here's to hoping that Android and iOS get some stiff competition in the future. Who doesn't want a less expensive smartphone that does incredibly cool stuff?

Why African Rhinos Are Facing a Crisis

The body count for African rhinos killed for their horns is approaching crisis proportions, according to the latest figures released by the International Union for Conservation of Nature (IUCN).

To National Geographic reporter Peter Gwin, the dire numbers—a rhinoceros slain every 11 minutes since the beginning of 2013—don't come as a surprise. "The killing will continue as long as criminal gangs know they can expect high profits for selling horns to Asian buyers," said Gwin, who wrote about the violent and illegal trade in rhino horn in the March 2012 issue of the magazine.

The recent surge in poaching has been fueled by a thriving market in Vietnam and China for rhino horn, used as a traditional medicine believed to cure everything from hangovers to cancer. Since 2011, at least 1,700 rhinos, or 7 percent of the total population, have been killed and their horns hacked off, according to the IUCN. More than two-thirds of the casualties occurred in South Africa, home to 73 percent of the world's wild rhinos. In Africa there are currently 5,055 black rhinos, listed as critically endangered by the IUCN, and 20,405 white rhinos. (From our blog: "South African Rhino Poaching Hits New High.")

Trying to snuff out poaching by itself won't work, said Gwin. The South African government is fighting a losing battle on the ground to gangs using helicopters, dart guns, high-powered weapons—and lots of money. (National Geographic pictures: The bloody poaching battle over rhino horn [contains graphic images].)

"Every year they get tougher on poaching, but rhino killings continue to rise astronomically," said Gwin. "Somehow they have to address the demand side in a meaningful way. This means either shutting down the Asian markets for rhino horn, or controversially, finding a way to sustainably harvest rhino horns, control their legal sale, and meet what appears to be a huge demand. Either will be a formidable endeavor."

Hope and Hurdles

The signing in December of a memorandum of understanding between South Africa and Vietnam to deal with rhino poaching and other conservation issues raises hope for some concrete action. Observers say the next step is for the two governments to follow through with tangible crime-stopping efforts such as intelligence sharing and other collaboration. The highest hurdle to stopping criminal trade, though, is cultural, Gwin believes. "In Vietnam and China, a lot of people simply believe that as a traditional cure, rhino horn works." (Related: "Blood Ivory.")

The recent climb in rhino deaths threatens what had been a conservation success story. Since 1995, due to better law enforcement, monitoring, and other actions, the overall rhino numbers have steadily risen. The poaching epidemic, the IUCN warns, could dramatically slow and possibly reverse population gains.

The population growth is also being stymied by South Africa's private game farmers, who breed rhinos for sport hunting and tourism and for many years have helped rebuild rhino numbers. Many of them are getting out of the business due to the high costs of security and other risks associated with the poaching invasions.

Those who still have rhinos on their farms will often pay a veterinarian to cut the horns off—under government supervision—to dissuade poachers, but the process costs more than $2,000 and has to be repeated when the horns grow back every two years. Even then the farmers are stuck with horns that are illegal to sell—and which criminals seek to obtain.

Room for Debate

Rhino killings and the trade in their horns will be a major topic at a high-profile conference, the 16th meeting of the Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which opens in Bangkok March 3. What won't surprise Gwin is if the issue of sustainably harvesting rhino horns from live animals comes up for discussion.

"It's an idea that seems to be gaining traction among some South African politicians and law enforcement circles," he said, noting that the international conservation community strongly opposes any talk of legalizing the trade of rhino horn, sustainably harvested or not. The bottom line for all parties in the discussion is clear, said Gwin: "The slaughter has to stop if rhinos are to survive."
