Attack at Algeria Gas Plant Heralds New Risks for Energy Development

Label:


The siege by Islamic militants at a remote Sahara desert natural gas plant in Algeria this week signaled heightened dangers in the region for international oil companies, at a time when they have been expanding operations in Africa as one of the world's last energy frontiers. (See related story: "Pictures: Four New Offshore Drilling Frontiers.")


As BP, Norway's Statoil, Italy's Eni, and other companies evacuated personnel from Algeria, it was not immediately clear how widely the peril would spread in the wake of the hostage-taking at the sprawling In Amenas gas complex near the Libyan border.

Algeria, the fourth-largest crude oil producer on the continent and a major exporter of natural gas and refined fuels, may not have been viewed as the most hospitable climate for foreign energy companies, but that was due to unfavorable financial terms, bureaucracy, and corruption. The energy facilities themselves appeared to be safe, with multiple layers of security provided both by the companies and by government forces, several experts said. (See related photos: "Oil States: Are They Stable? Why It Matters.")


"It is particularly striking not only because it hasn't happened before, but because it happened in Algeria, one of the stronger states in the region," says Hanan Amin-Salem, a senior manager at the industry consulting firm PFC Energy, who specializes in country risk. She noted that in the long civil war that gripped the country throughout the 1990s, there had never been an attack on Algeria's energy complex. But now, hazard has spread from weak surrounding states, as the assault on In Amenas was carried out in an apparent retaliation for a move by French forces against the Islamists who had taken over Timbuktu and other towns in neighboring Mali. (See related story: "Timbuktu Falls.")


"What you're really seeing is an intensification of the fundamental problem of weak states, and empowerment of heavily armed groups that are really well motivated and want to pursue a set of aims," said Amin-Salem. In PFC Energy's view, she says, risk has increased in Mauritania, Chad, and Niger—indeed, throughout Sahel, the belt that bisects North Africa, separating the Sahara in the north from the tropical forests further south.


On Thursday, the London-based corporate consulting firm Exclusive Analysis, which was recently acquired by the global consultancy IHS, sent an alert to clients warning that oil and gas facilities near the Libyan and Mauritanian borders and in Mauritania's Hodh Ech Chargui province were at "high risk" of attack by jihadis.


"A Hot Place to Drill"


The attack at In Amenas comes at a time of unprecedented growth for the oil industry in Africa. (See related gallery: "Pictures: The Year's Most Overlooked Energy Stories.") Forecasters expect that oil output throughout Africa will double by 2025, says Amy Myers Jaffe, executive director of the energy and sustainability program at the University of California, Davis, who has counted 20 rounds of bidding for new exploration at sites in Africa's six largest oil-producing states.


Oil and natural gas are a large part of the Algerian economy, accounting for 60 percent of government budget revenues, more than a third of GDP and more than 97 percent of its export earnings. But the nation's resources are seen as largely undeveloped, and Algeria has tried to attract new investment. Over the past year, the government has sought to reform the law to boost foreign companies' interests in their investments, although those efforts have foundered.


Technology has been one of the factors driving the opening up of Africa to deeper energy exploration. Offshore and deepwater drilling success in the Gulf of Mexico and Brazil led to prospecting now under way offshore in Ghana, Mozambique, and elsewhere. (See related story: "New Oil—And a Huge Challenge—for Ghana.") Jaffe says the Houston-based company Anadarko Petroleum has sought to transfer its success in "subsalt seismic" exploration technology, surveying reserves hidden beneath the hard salt layer at the bottom of the sea, to the equally challenging seismic exploration beneath the sands of the Sahara in Algeria, where it now has three oil and gas operations.


Africa also is seen as one of the few remaining oil-rich regions of the world where foreign oil companies can obtain production-sharing agreements with governments, contracts that allow them a share of the revenue from the barrels they produce, instead of more limited service contracts for work performed.


"You now have the technology to tap the resources more effectively, and the fiscal terms are going to be more attractive than elsewhere—you put these things together and it's been a hot place to drill," says Jaffe, who doesn't see the energy industry's interest in Africa waning, despite the increased terrorism risk. "What I think will happen in some of these countries is that the companies are going to reveal new securities systems and procedures they have to keep workers safe," she says. "I don't think they will abandon these countries."

Opinion: Lance One of Many Tour de France Cheaters

Label:

Editor's note: England-based writer and photographer Roff Smith rides around 10,000 miles a year through the lanes of Sussex and Kent and writes a cycling blog at: www.my-bicycle-and-I.co.uk

And so, the television correspondent said to the former Tour de France champion, a man who had been lionised for years, feted as the greatest cyclist of his day, did you ever use drugs in the course of your career?

"Yes," came the reply. "Whenever it was necessary."

"And how often was that?" came the follow-up question.

"Almost all the time!"

This is not a leak of a transcript from Oprah Winfrey's much anticipated tell-all with disgraced cyclist Lance Armstrong, but instead was lifted from a decades-old interview with Fausto Coppi, the great Italian road cycling champion of the 1940s and 1950s.

To this day, though, Coppi is lauded as one of the gods of cycling, an icon of a distant and mythical golden age in the sport.

So is five-time Tour winner Jacques Anquetil (1957, 1961-64) who famously remarked that it was impossible "to ride the Tour on mineral water."

"You would have to be an imbecile or a crook to imagine that a professional cyclist who races for 235 days a year can hold the pace without stimulants," Anquetil said.

And then there's British cycling champion Tommy Simpson, who died of heart failure while trying to race up Mont Ventoux during the 1967 Tour de France, a victim of heat, stress, and a heady cocktail of amphetamines.

All are heroes today. If their performance-enhancing peccadillos are not forgotten, they have at least been glossed over in the popular imagination.

As the latest chapter of the sorry Lance Armstrong saga unfolds, it is worth looking at the history of cheating in the Tour de France to get a sense of perspective. This is not an attempt at rationalisation or justification for what Lance did. Far from it.

But the simple, unpalatable fact is that cheating, drugs, and dirty tricks have been part and parcel of the Tour de France nearly from its inception in 1903.

Cheating was so rife in the 1904 event that Henri Desgrange, the founder and organiser of the Tour, declared he would never run the race again. Not only was the overall winner, Maurice Garin, disqualified for taking the train over significant stretches of the course, but so were next three cyclists who placed, along with the winner of every single stage of the course.

Of the 27 cyclists who actually finished the 1904 race, 12 were disqualified and given bans ranging from one year to life. The race's eventual official winner, 19-year-old Henri Cornet, was not determined until four months after the event.

And so it went. Desgrange relented on his threat to scrub the Tour de France and the great race survived and prospered-as did the antics. Trains were hopped, taxis taken, nails scattered along the roads, partisan supporters enlisted to beat up rivals on late-night lonely stretches of the course, signposts tampered with, bicycles sabotaged, itching powder sprinkled in competitors' jerseys and shorts, food doctored, and inkwells smashed so riders yet to arrive couldn't sign the control documents to prove they'd taken the correct route.

And then of course there were the stimulants-brandy, strychnine, ether, whatever-anything to get a rider through the nightmarishly tough days and nights of racing along stages that were often over 200 miles long. In a way the race was tailor-made to encourage this sort of thing. Desgrange once famously said that his idea of a perfect Tour de France would be one that was so tough that only one rider finished.

Add to this the big prizes at a time when money was hard to come by, a Tour largely comprising young riders from impoverished backgrounds for whom bicycle racing was their one big chance to get ahead, and the passionate following cycling enjoyed, and you had the perfect recipe for a desperate, high stakes, win-at-all-costs mentality, especially given the generally tolerant views on alcohol and drugs in those days.

After World War II came the amphetamines. Devised to keep soldiers awake and aggressive through long hours of battle they were equally handy for bicycle racers competing in the world's longest and toughest race.

So what makes the Lance Armstrong story any different, his road to redemption any rougher? For one thing, none of the aforementioned riders were ever the point man for what the U.S. Anti-Doping Agency has described in a thousand-page report as the most sophisticated, cynical, and far-reaching doping program the world of sport has ever seen-one whose secrecy and efficiency was maintained by ruthlessness, bullying, fear, and intimidation.

Somewhere along the line, the casualness of cheating in the past evolved into an almost Frankenstein sort of science in which cyclists, aided by creepy doctors and trainers, were receiving blood transfusions in hotel rooms and tinkering around with their bodies at the molecular level many months before they ever lined up for a race.

To be sure, Armstrong didn't invent all of this, any more than he invented original sin-nor was he acting alone. But with his success, money, intelligence, influence, and cohort of thousand-dollar-an-hour lawyers-and the way he used all this to prop up the Lance brand and the Lance machine at any cost-he became the poster boy and lightning rod for all that went wrong with cycling, his high profile eclipsing even the heads of the Union Cycliste Internationale, the global cycling union, who richly deserve their share of the blame.

It is not his PED popping that is the hard-to-forgive part of the Lance story. Armstrong cheated better than his peers, that's all.

What I find troubling is the bullying and calculated destruction of anyone who got in his way, raised a question, or cast a doubt. By all accounts Armstrong was absolutely vicious, vindictive as hell. Former U.S. Postal team masseuse Emma O'Reilly found herself being described publicly as a "prostitute" and an "alcoholic," and had her life put through a legal grinder when she spoke out about Armstrong's use of PEDs.

Journalists were sued, intimidated, and blacklisted from events, press conferences, and interviews if they so much as questioned the Lance miracle or well-greased machine that kept winning Le Tour.

Armstrong left a lot of wreckage behind him.

If he is genuinely sorry, if he truly repents for his past "indiscretions," one would think his first act would be to try to find some way of not only seeking forgiveness from those whom he brutally put down, but to do something meaningful to repair the damage he did to their lives and livelihoods.

6 Ways Climate Change Will Affect You

Label:

Photograph by AP Photo/Marcio Jose Sanchez

The planet keeps getting hotter, new data showed this week. Especially in America, where 2012 was the warmest year ever recorded, by far. Every few years, the U.S. federal government engages hundreds of experts to assess the impacts of climate change, now and in the future.

From agriculture (pictured) to infrastructure to how humans consume energy, the National Climate Assessment Development Advisory Committee spotlights how a warming world may bring widespread disruption.

Farmers will see declines in some crops, while others will reap increased yields.

Won't more atmospheric carbon mean longer growing seasons? Not quite. Over the next several decades, the yield of virtually every crop in California's fertile Central Valley, from corn to wheat to rice and cotton, will drop by up to 30 percent, researchers expect. (Read about "The Carbon Bathtub" in National Geographic magazine.)

Lackluster pollination, driven by declines in bees due partly to the changing climate, is one reason. Government scientists also expect the warmer climate to shorten the length of the frosting season necessary for many crops to grow in the spring.

Aside from yields, climate change will also affect food processing, storage, and transportation—industries that require an increasing amount of expensive water and energy as global demand rises—leading to higher food prices.

Mars Rover Finds Intriguing New Evidence of Water

Label:

The first drill sample ever collected on Mars will come from a rockbed shot through with unexpected veins of what appears to be the mineral gypsum.

Delighted members of the Curiosity science team announced Tuesday that the rover was now in a virtual "candy store" of scientific targets—the lowest point of Gale crater, called Yellowknife Bay, is filled with many different materials that could have been created only in the presence of water. (Related: "Mars Has 'Oceans' of Water Inside?")

Project scientist John Grotzinger, of the California Institute of Technology in Pasadena, said during a press conference that the drill area has turned out "to be jackpot unit. Every place we drive exposes fractures and vein fills."

Mission scientists initially decided to visit the depression, a third of a mile from Curiosity's landing site, on a brief detour before heading to the large mountain at the middle of Gale Crater. But because of the richness of their recent finds, Grotzinger said it may be some months before they begin their trek to Mount Sharp.

The drilling, expected to start this month, will dig five holes about two inches (five centimeters) into bedrock the size of a throw rug and then feed the powder created to the rover's two chemistry labs for analysis.

The drill is the most complex device on the rover and is the last instrument to be used. Project Manager Richard Cook, of NASA's Jet Propulsion Laboratory, said that operating it posed the biggest mechanical challenge since Curiosity's high-drama landing. (Watch video of Curiosity's "Seven Minutes of Terror.")

A Watery Past?

That now-desiccated Mars once had a significant amount of surface water is now generally accepted, but every new discovery of when and where water was present is considered highly significant. The presence of surface water in its many possible forms—as a running stream, as a still lake, as ground water soaked into the Martian soil—all add to an increased possibility that the planet was once habitable. (Watch a video about searching for life on Mars.)

And each piece of evidence supporting the presence of water brings the Curiosity mission closer to its formal goal—which is to determine whether Mars was once capable of supporting life.

Curiosity scientists have already concluded that a briskly moving river or stream once flowed near the Gale landing site.

The discovery of the mineral-filled veins within Yellowknife Bay rock fractures adds to the picture because those minerals can be deposited only in watery, underground conditions.

The Curiosity team has also examined Yellowknife Bay for sedimentary rocks with the rover's Mars Hand Lens Imager (MAHLI).  Scientists have found sandstone with grains up to about the size of a peppercorn, including one shaped like a flower bud that appears to gleam. Other nearby rocks are siltstone, with grains finer than powdered sugar. These are quite different from the pebbles and conglomerate rocks found in the landing area, but all these rocks are evidence of a watery past. (Related: "A 2020 Rover Return to Mars?")

One of the primary reasons Curiosity scientists selected Gale crater as a landing site was because satellite images indicated that water-formed minerals were present near the base of Mount Sharp. Grotzinger said that the minerals' presence so close to the landing site, and some five miles from the mountain, is both a surprise and an opportunity.

The current site in Yellowknife Bay is so promising, Grotzinger said, that he would have been "thrilled" to find similar formations at the mission's prime destination at the base of Mount Sharp.  Now the mission can look forward to the surprises to come at the mountain base while already having struck gold.

"Fantastic" New Flying Frog Found—Has Flappy Forearms

Label:

Scientists have stumbled across a new species of flying frog—on the ground.

While hiking a lowland forest in 2009, not far from Ho Chi Minh City (map), Vietnam, "we came across a huge green frog, sitting on a log," said Jodi Rowley, an amphibian biologist at the Australian Museum in Sydney and lead author of a new study on the frog.

Rowley later discovered that the 3.5-inch-long (9-centimeter-long) creature is a relatively large new type of flying frog, a group known for its ability to "parachute" from tree to tree thanks to special aerodynamic adaptations, such as webbed feet, Rowley said. (Also see "'Vampire Flying Frog' Found; Tadpoles Have Black Fangs.")

Rowley dubbed the new species Helen's flying frog, in honor of her mother, Helen Rowley, "who has steadfastly supported her only child trekking through the forests of Southeast Asia in search of frogs," according to a statement.

The newfound species—there are 80 types of flying frogs—is also "one of the most flying frogs of the flying frogs," Rowley said, "in that it's got huge hands and feet that are webbed all the way to the toepad."

"Females even have flappy skin on their forearms to glide," added Rowley, who has received funding from the National Geographic Committee on Research and Exploration. (National Geographic News is part of the National Geographic Society.) "The females are larger and heavier than males, so the little extra flaps probably don't make much of a difference," she said.

As Rowley wrote on her blog, "At first it may seem strange that such a fantastic and obvious frog could escape discovery until now—less than 100 kilometers [60 miles] from an urban centre with over nine million people."

Yet these tree dwellers can easily escape notice—they spend most of their time in the canopy, she said.

Flying Frog On the Edge

Even so, Helen's flying frog won't be able to hide from development near Ho Chi Minh City, which may encroach on its existing habitats.

So far, only five individuals have been found in two patches of lowland forest hemmed in by rice paddies in southern Vietnam, Rowley said. The animals can probably tolerate a little bit of disturbance as long as they have large trees and temporary pools, she added.

But lowland forests are among the most threatened habitats in the world, mostly because they're so accessible to people, and thus chosen for logging and development. (Get the facts on deforestation.)

"While Helen's flying frog has only just been discovered by biologists," Rowley wrote, "unfortunately this species, like many others, is under great threat from ongoing habitat loss and degradation."

The new flying frog study was published in December 2012 in the Journal of Herpetology.

A fishing net, likely only decades old, drapes over machinery that once connected the Hatteras' pistons to its paddle wheels, said Delgado.

From archived documents, the NOAA archaeologist learned that Blake, the ship's commander, surrendered as his ship was sinking. "It was listing to port, [or the left]," Delgado said. The Alabama took the wounded and the rest of the crew and put them in irons.

The officers were allowed to keep their swords and wander the deck as long as they promised not to lead an uprising against the Alabama's crew, he added.

From there, the Alabama dropped off their captives in Jamaica, leaving them to make their own way back to the U.S.

Delgado wants to dig even further into the crew of the Hatteras. He'd like see if members of the public recognize any of the names on his list of crew members and can give him background on the men.

"That's why I do archaeology," he said.

A fishing net, likely only decades old, drapes over machinery that once connected the Hatteras' pistons to its paddle wheels, said Delgado.

From archived documents, the NOAA archaeologist learned that Blake, the ship's commander, surrendered as his ship was sinking. "It was listing to port, [or the left]," Delgado said. The Alabama took the wounded and the rest of the crew and put them in irons.

The officers were allowed to keep their swords and wander the deck as long as they promised not to lead an uprising against the Alabama's crew, he added.

From there, the Alabama dropped off their captives in Jamaica, leaving them to make their own way back to the U.S.

Delgado wants to dig even further into the crew of the Hatteras. He'd like see if members of the public recognize any of the names on his list of crew members and can give him background on the men.

"That's why I do archaeology," he said.

Google and Twitter Help Track Influenza Outbreaks

Label:

This flu season could be the longest and worst in years. So far 18 children have died from flu-related symptoms, and 2,257 people have been hospitalized.

Yesterday Boston Mayor Thomas Menino declared a citywide public health emergency, with roughly 700 confirmed flu cases—ten times the number the city saw last year.

"It arrived five weeks early, and it's shaping up to be a pretty bad flu season," said Lyn Finelli, who heads the Influenza Outbreak Response Team at the Centers for Disease Control and Prevention (CDC).

Boston isn't alone. According to the CDC, 41 states have reported widespread influenza activity, and in the last week of 2012, 5.6 percent of doctor's office visits across the country were for influenza-like illnesses. The severity likely stems from this year's predominant virus: H3N2, a strain known to severely affect children and the elderly. Finelli notes that the 2003-2004 flu season, also dominated by H3N2, produced similar numbers. (See "Are You Prepped? The Influenza Roundup.")

In tracking the flu, physicians and public health officials have a host of new surveillance tools at their disposal thanks to crowdsourcing and social media. Such tools let them get a sense of the flu's reach in real time rather than wait weeks for doctor's offices and state health departments to report in.

Pulling data from online sources "is no different than getting information on over-the-counter medication or thermometer purchases [to track against an outbreak]," said Philip Polgreen, an epidemiologist at the University of Iowa.

The most successful of these endeavors, Google Flu Trends, analyzes flu-related Internet search terms like "flu symptoms" or "flu medication" to estimate flu activity in different areas. It tracks flu outbreaks globally.

Another tool, HealthMap, which is sponsored by Boston Children's Hospital, mines online news reports to track outbreaks in real time. Sickweather draws from posts on Twitter and Facebook that mention the flu for its data.

People can be flu-hunters themselves with Flu Near You, a project that asks people to report their symptoms once a week. So far more than 38,000 people have signed up for this crowdsourced virus tracker. And of course, there's an app for that.

Both Finelli, a Flu Near You user, and Polgreen find the new tools exciting but agree that they have limits. "It's not as if we can replace traditional surveillance. It's really just a supplement, but it's timely," said Polgreen.

When people have timely warning that there's flu in the community, they can get vaccinated, and hospitals can plan ahead. According to a 2012 study in Clinical Infectious Diseases, Google Flu Trends has shown promise predicting emergency room flu traffic. Some researchers are even using a combination of the web database and weather data to predict when outbreaks will peak.

As for the current flu season, it's still impossible to predict week-to-week peaks and troughs. "We expect that it will last a few more weeks, but we can never tell how bad it's going to get," said Finelli.

Hospitals are already taking precautionary measures. One Pennsylvania hospital erected a separate emergency room tent for additional flu patients. This week, several Illinois hospitals went on "bypass," alerting local first responders that they're at capacity—due to an uptick in both flu and non-flu cases—so that patients will be taken to alternative facilities, if possible.

In the meantime, the CDC advises vaccination, first and foremost. On the bright side, the flu vaccine being used this year is a good match for the H3N2 strain. Though Finelli cautions, "Sometimes drifted strains pop up toward the end of the season."

It looks like there won't be shortages of seasonal flu vaccine like there have been in past years. HealthMap sports a Flu Vaccine Finder to make it a snap to find a dose nearby. And if the flu-shot line at the neighborhood pharmacy seems overwhelming, more health departments and clinics are offering drive-through options.

Embryonic Sharks Freeze to Avoid Detection

Label:

Jane J. Lee


Although shark pups are born with all the equipment they'll ever need to defend themselves and hunt down food, developing embryos still stuck in their egg cases are vulnerable to predators. But a new study finds that even these baby sharks can detect a potential predator, and play possum to avoid being eaten.

Every living thing gives off a weak electrical field. Sharks can sense this with a series of pores—called the ampullae of Lorenzini—on their heads and around their eyes, and some species rely on this electrosensory ability to find food buried in the seafloor. (See pictures of electroreceptive fish.)

Two previous studies on the spotted catshark (Scyliorhinus canicula) and the clearnose skate (Raja eglanteria)—a relative of sharks—found similar freezing behavior in their young. But new research by shark biologist and doctoral student Ryan Kempster at the University of Western Australia has given scientists a more thorough understanding of this behavior.

It all started because Kempster wanted to build a better shark repellent. Since he needed to know how sharks respond to electrical fields, Kempster decided to use embryos. "It's very hard to test this in the field because you need to get repeated responses," he said. And you can't always get the same shark to cooperate multiple times. "But we could use embryos because they're contained within an egg case."

Cloaking Themselves

So Kempster got his hands on 11 brownbanded bamboo shark (Chiloscyllium punctatum) embryos and tested their reactions to the simulated weak electrical field of a predator. (Popular pictures: Bamboo shark swallowed whole—by another shark.)

In a study published today in the journal PLoS One, Kempster and his colleagues report that all of the embryonic bamboo sharks, once they reached later stages of development, reacted to the electrical field by ceasing gill movements (essentially, holding their breath), curling their tails around their bodies, and freezing.

A bamboo shark embryo normally beats its tail to move fresh seawater in and out of its egg case. But that generates odor cues and small water currents that can give away its position. The beating of its gills as it breathes also generates an electrical field that predators can use to find it.

"So it cloaks itself," said neuroecologist Joseph Sisneros, at the University of Washington in Seattle, who was not involved in the study. "[The embryo] shuts down any odor cues, water movement, and its own electrical signal."

Sisneros, who conducted the previous clearnose skate work, is delighted to see that this shark species also reacts to external electrical fields and said it would be great to see whether this is something all shark, skate, and ray embryos do.

Marine biologist Stephen Kajiura, at Florida Atlantic University, is curious to know how well the simulated electrical fields compare to the bamboo shark's natural predators—the experimental field was on the higher end of the range normally given off.

"[But] they did a good job with [the study]," Kajiura said. "They certainly did a more thorough study than anyone else has done."

Electrifying Protection?

In addition to the freezing behavior he recorded in the bamboo shark embryos, Kempster found that the shark pups remembered the electrical field signal when it was presented again within 40 minutes and that they wouldn't respond as strongly to subsequent exposures as they did initially.

This is important for developing shark repellents, he said, since some of them use electrical fields to ward off the animals. "So if you were using a shark repellent, you would need to change the current over a 20- to 30-minute period so the shark doesn't get used to that field."

Kempster envisions using electrical fields to not only keep humans safe but to protect sharks as well. Shark populations have been on the decline for decades, due partly to ending up as bycatch, or accidental catches, in the nets and on the longlines of fishers targeting other animals.

A 2006 study estimated that as much as 70 percent of landings, by weight, in the Spanish surface longline fleet were sharks, while a 2007 report found that eight million sharks are hooked each year off the coast of southern Africa. (Read about the global fisheries crisis in National Geographic magazine.)

"If we can produce something effective, it could be used in the fishing industry to reduce shark bycatch," Kempster said. "In [America] at the moment, they're doing quite a lot of work trying to produce electromagnetic fish hooks." The eventual hope is that if these hooks repel the sharks, they won't accidentally end up on longlines.

Smoke from a wildfire mushrooms over a beach in Forcett, Tasmania, on January 4. (See more wildfire pictures.)

Wildfires have engulfed southeastern Australia, including the island state of Tasmania, in recent days, fueled by dry conditions and temperatures as high as 113ºF (45ºC), the Associated Press reported. (Read "Australia's Dry Run" inNational Geographic magazine.)

No deaths have been reported, though a hundred people are unaccounted for in the town of Dunalley, where the blazes destroyed 90 homes.

"You don't get conditions worse than this," New South Wales Rural Fire Service Commissioner Shane Fitzsimmons told the AP.

"We are at the catastrophic level, and clearly in those areas leaving early is your safest option."

Primitive and Peculiar Mammal May Be Hiding Out in Australia

Label:


It’d be hard to think of a mammal that’s weirder than the long-beaked, egg-laying echidna. Or harder to find.


Scientists long thought the animal, which has a spine-covered body, a four-headed penis, and a single hole for reproducing, laying eggs, and excreting waste, lived only in New Guinea. The population of about 10,000 is critically endangered. Now there is tantalizing evidence that the echidna, thought to have gone extinct in Australia some 10,000 years ago, lived and reproduced there as recently as the early 1900s and may still be alive on Aussie soil.


The new echidna information comes from zoologist Kristofer Helgen, a National Geographic emerging explorer and curator of mammals at the Smithsonian Institution. Helgen has published a key finding in ZooKeys confirming that a skin and skull collected in 1901 by naturalist John T. Tunney in Australia is in fact the western long-beaked echidna, Zaglossus bruijnii. The specimen, found in the West Kimberley region of Western Australia, was misidentified for many years.


(More about echidnas: Get to know this living link between mammals and reptiles.)


Helgen has long been fascinated by echidnas. He has seen only three in the wild. “Long-beaked echidnas are hard to get your hands on, period,” he said. “They are shy and secretive by nature. You’re lucky if you can find one. And if you do, it will be by chance.” Indeed, chance played a role in his identification of the Australian specimen. In 2009, he visited the Natural History Museum of London, where he wanted to see all of the echidnas he could. He took a good look in the bottom drawer of the echidna cabinet, where the specimens with less identifying information are often stored. From among about a dozen specimens squeezed into the drawer, he grabbed the one at the very bottom.


(Related from National Geographic magazine: “Discovery in the Foja Mountains.”)


“As I pulled it out, I saw a tag that I had seen before,” Helgen said. “I was immediately excited about this label. As a zoologist working in museums you get used to certain tags: It’s a collector’s calling card. I instantly recognized John Tunney’s tag and his handwriting.”


John Tunney was a well-known naturalist in the early 20th century who went on collecting expeditions for museums. During an Australian expedition in 1901 for Lord L. Walter Rothschild’s private museum collection, he found the long-beaked echidna specimen. Though he reported the locality on his tag as “Mt Anderson (W Kimberley)” and marked it as “Rare,” Tunney left the species identification field blank. When he returned home, the specimen was sent to the museum in Perth for identification. It came back to Rothschild’s museum identified as a short-beaked echidna.


With the specimen’s long snout, large size, and three-clawed feet, Helgen knew that it must be a long-beaked echidna. The short-beaked echidna, still alive and thriving in Australia today, has five claws, a smaller beak, and is half the size of the long-beaked echidna, which can weigh up to 36 pounds (16 kilograms).



As Helgen began tracing the history and journey of the specimen over the last century, he crossed the path of another fascinating mind who had also encountered the specimen. Oldfield Thomas was arguably the most brilliant mammalogical taxonomist ever. He named approximately one out of every six mammals known today.


Thomas was working at the Natural History Museum in London when the Tunney echidna specimen arrived, still misidentified as a short-beaked echidna. Thomas realized the specimen was actually a long-beaked echidna and removed the skull and some of the leg bones from the skin to prove that it was an Australian record of a long-beaked echidna, something just as unexpected then as it is now.


No one knows why Thomas did not publish that information. And the echidna went back into the drawer until Helgen came along 80 years later.


As Helgen became convinced that Tunney’s long-beaked echidna specimen indeed came from Australia, he confided in fellow scientist Mark Eldridge of the Australian Museum about the possibility. Eldridge replied, “You’re not the first person who’s told me that there might be long-beaked echidnas in the Kimberley.” (That’s the Kimberley region of northern Australia.) Scientist James Kohen, a co-author on Helgen’s ZooKeys paper, had been conducting fieldwork in the area in 2001 and spoke to an Aboriginal woman who told him how “her grandmothers used to hunt” large echidnas.


This is “the first evidence of the survival into modern times of any long-beaked echidna in Australia,” said Tim Flannery, professor at Macquarie University in Sydney. “This is a truly significant finding that should spark a re-evaluation of echidna identifications from across northern Australia.”


Helgen has “a small optimism” about finding a long-beaked echidna in the wild in Australia and hopes to undertake an expedition and to interview Aboriginal communities, with their intimate knowledge of the Australian bush.


Though the chances may be small, Helgen says, finding one in the wild “would be the beautiful end to the story.”

Powder-splattered, and powder-splattering, runners cross the finish line of The Color Run 5K in Irvine, California, on April 22. Each kilometer (0.6 mile) of the event features a color-pelting station dedicated to a single hue, culminating in the Pollock-esque riot at kilometer 5.

The "magical color dust" is completely safe, organizers say, though they admit it's "surprisingly high in calories and leaves a chalky aftertaste."

Pictures: Errant Shell Oil Rig Runs Aground Off Alaska, Prompts Massive Response

Label:

Photograph courtesy Jonathan Klingenberg, U.S. Coast Guard

Waves lash at the sides of the Shell* drilling rig Kulluk, which ran aground off the rocky southern coast of Alaska on New Year's Eve in a violent storm.

The rig, seen above Tuesday afternoon, was "stable," with no signs of spilled oil products, authorities said. But continued high winds and savage seas hampered efforts to secure the vessel and the 150,000 gallons (568,000 liters) of diesel fuel and lubricants on board. The Kulluk came to rest just east of Sitkalidak Island (map), an uninhabited but ecologically and culturally rich site north of Ocean Bay, after a four-day odyssey, during which it broke free of its tow ships and its 18-member crew had to be rescued by helicopter.

The U.S. Coast Guard, state, local, and industry officials have joined in an effort involving nearly 600 people to gain control of the rig, one of two that Shell used for its landmark Arctic oil-drilling effort last summer. "This must be considered once of the largest marine-response efforts conducted in Alaska in many years," said Steve Russell, of Alaska's Department of Environmental Conservation.

The 266-foot (81-meter) rig now is beached off one of the larger islands in the Kodiak archipelago, a land of forest, glaciers, and streams about 300 miles (482 kilometers) south of Anchorage. The American Land Conservancy says that Sitkalidak Island's highly irregular coastline traps abundant food sources upwelling from the central Gulf of Alaska, attracting large numbers of seabirds and marine mammals. The largest flock of common murres ever recorded by the U.S. Fish and Wildlife Service was in Sitkalidak Strait, which separates the island from Kodiak. Sitkalidak also has 16 wild salmon rivers and archaeological sites tied to the Alutiiq native peoples dating back more than 7,000 years.

Shell incident commander Susan Childs said Monday night that the company's wildlife management team had started to assess the potential impact of a spill, and would be dispatched to the site when the weather permitted. She said the Kulluk's fuel tanks were in the center of the vessel, encased in heavy steel. "The Kulluk is a pretty sturdy vessel," she said. " It just remains to be seen how long it's on the shoreline and how long the weather is severe."
