10 Strange Nat Geo Discoveries of 2009
National Geographic News’s most popular coverage of 2009 scientific finds is swarming with megamouth sharks, giant snakes, a transparent-headed fish, “Jacques Cousteau” clouds , and rare species rescued from obscurity—then eaten.
Top 10 National Geographic Discoveries of 2009
10. Ultra-Rare Megamouth Shark Found, Eaten
In March, the 41st megamouth shark ever found went from swimming in Philippine waters to simmering in coconut milk.
9. Ancient Gem-Studded Teeth Show Skill of Early Dentists
The glittering “grills” of some hip-hop stars aren’t exactly unprecedented. Sophisticated dentistry allowed Native Americans to add bling to their teeth as far back as 2,500 years ago, a May study said.
8. Alien Giant Snakes Threaten to Invade Up to 1/3 of U.S.
Nine giant snakes could be on the verge of causing ecological catastrophe if they establish themselves in the U.S. wild—at least two have already set up shop in Florida—according to an October report.
7. Biggest Snake Discovered; Was Longer Than a Bus
The 60-million-year-old reptile was also heavier than a car, scientists said in February, adding that the fossil could shed light on climate change.
6. Gold Rush-Era “Ghost Ship” Wreck Found
With boots thrown hastily on deck and cooking utensils scattered, the last moments of the crew aboard the gold rush-era paddleboat A.J. Goddard are preserved in the ship’s recently found wreck, archaeologists announced in November.
5. Oldest Skeleton of Human Ancestor Found
There was never a chimp-like missing link between humans and today’s apes, according to an October fossil-skeleton study that could rewrite human evolutionary history. Said one scientist, “It changes everything.”
4. “Extinct” Bird Seen, Eaten
Long believed to be extinct, a rare quail from the Philippines was photographed for the first time ever—then sold at a poultry market, experts said in February.
3. New Cloud Type Discovered?
Nicknamed “Jacques Cousteau” clouds, these “turbulent” seas in the sky could be examples of the first official new cloud type since 1951, experts said in June.
2. Fish With Transparent Head Seen Alive for First Time
Perhaps the most bizarre nature discovery of the year—though Stephen Colbert put it a bit less delicately—a Pacific barreleye fish shows off its transparent head and barrel-like eyes in pictures released on February of the first specimen ever found alive.
1. “Missing Link” Found: Fossil Connects Humans, Lemurs?
The 47-million-year-old, exceptionally preserved primate fossil “Ida,” unveiled on May 20, was hailed by some as a major discovery in human evolution.
The publicity frenzy made National Geographic News’s brief coverage our most viewed page of the year—and inspired a backlash as some experts, including one here at Nat Geo HQ, suggested Ida was more media event than milestone.

10 of the World's Strange and BizarreJobs
(1) Janitor at a Porno Theatre
Janitor, in itself, is a pretty bad job. But, porno theater janitor is the worst job on the list. The main responsibility of the porno theater janitor is to take his mop and rag and wide up after each show is finished. Unlike a traditional theater, it's safe to assume that sticky substance under the chair is something other than Coca-Cola Classic! At least you get to see all that porn for free and you'll probably be very popular among your male friends, although this is probably not a job you want to talk about with your mother, or your wife for that matter.
(2) Guard at Buckingham Palace
Guard duty at Buckingham Palace is regarded as one of the worst jobs in the British Army. Besides the fact that they have to stand for hours, no laughing allowed, they also have to look their best. Soldiers spend several hours each day cleaning and pressing their uniforms and polishing their boots in preparation for one of the many kit inspections that they are likely to face before taking up their positions outside one of the royal palaces. Any soldier whose turn-out is less than immaculate is likely to face a variety of punishments, such as extra guard duty.
(3) Animal Masturbator
Researchers who want animal sperm -to study fertility or for artificial insemination-have a suite of attractive options: They can ram an electric probe up an animal's rectum, shove an artificial
vagina onto the animal's penis, or simply do it the old-fashioned way-manual stimulation. The first option, electroejaculation, uses a priapic rectal probe to send electricity pulsing through the animal's nether regions. "All the normal excitatory signals that stimulate ejaculation, like touch, sight, sound and smell, can be replaced with the current from the probe," says Trish Berger, professor of animal science at the University of California, Davis. "It's fascinating. Of course, this is a woman talking." Electroejaculation generally requires anesthetizing the animal and is typically used on zoo dwellers. The other two methods-the artificial vagina, or AV, and the good old hand-require that animals be trained to the procedure. The AV-a large latex tube coated with warm lubricant -is used primarily to get sperm from dairy bulls (considered the most ornery and dangerous of bovines). The bull gets randy with a steer; when he mounts the steer with his forelegs, a brave technician, AV in hand, insinuates himself between the two aroused beasts and deftly redirects the bull's penis into the mock genitalia, which he must then hold tight while the bull orgasms. (Talk about bull riding!) Three additional technicians attempt to ensure this (fool)hardy soul's safety by anchoring themselves to restraining ropes attached to a ring in the bull's nose. Alas, this isn't always absolutely effective: Everyone who's wielded an AV has had at least one close call, and more than a few have been sent to the hospital. The much safer "digital pressure" is used mostly with pigs, who are trained from an early age to mount a small bench while the researcher reaches around with a gloved hand and provides appropriate pleasure-er, pressure.
(4) Sewers Cleaner
Ramesh Sahu works in the sanitation department of Calcutta, cleaning out the city's sewers. On a regular basis, Rakesh sits in a low crouch at the bottom of a seven-foot-deep manhole, sloshing away in a swirl of human waste and sediment. Equipped with a hoe and a steel bar, and wearing only a pair of loose purple underpants, Rakesh empties the thick black sludge from a clogged sewer into a bucket that his fellow crew members hoist up and dump in the middle of a narrow road. A small mountain of decaying excrement accumulates between the manhole and a rickety wooden vegetable cart. Two co-workers reach down and yank Rakesh out by his sore, extended arms, his body splattered with putrid muck. At 27, with a wife, three young daughters and a monthly income of about $100, he has been a sewage worker for the Delhi Jal (Water) Board for the past 10 years.
(5) Brazilian Mosquito Researcher
Scientists fighting malaria must study the biting habits of the mosquito that spreads it. In Brazil, that's the Anopheles Darlingi, which doesn't fall for the light or wind traps researchers use in Africa: this smart little sucker will come near scientists only when they offer themselves as bait. In the early evening, when mosquito activity is busiest, a mosquito dinner- researcher finds a nice buggy area and sets himself up inside a mosquito-netting tent with a gap at the bottom. Mosquitoes fly in low and get trapped inside, where the researcher sits stoically, sacrificing his skin to science. He needs focus only on his legs to keep him busy: whenever a mosquito chooses a drumstick dinner, the researcher draws it into a mouth tube and then expels it into a container. Veteran researcher Helge Zieler used to put himself on the menu twice a week. On his best evening, he caught 500 Anopheles in 3 hours. Meanwhile, of course, the skeeters feasted on his entire corpus-a grand total of about 3,000 bites, or an average of 17 per minute for 180 minutes on end. "It's not so bad," he says, explaining that his personal response to mosquito bites is an immediate itch that goes away naturally in a few minutes. Except when his response is to contractmalaria. Despite taking prophylactic chloroquine, Zieler developed a case that took him two years to shake.
(6) Portable Toilet Cleaner
This job is a sort of combination of garbage collector and gastroenterologist, and arguably more disgusting than both put together. Although most people in polite society methodically avoid situations where they need to use a portable toilet, modern outhouses can be lifesavers. As gross as they can be, they'd be worse without the folks who clean them for a living. Using a tank and a vacuum wand, cleaners must suck up all the waste in aportable toilet. After picking up any stray toilet paper, they also wash down all surfaces that could possibly be soiled, including the walls. This is when a high-pressure hose comes in handy. Usually, cleaning one portable toilet takes only a few minutes, and most workers clean from 10 to 60 of them a day. But it's not always that easy: Portable toilets that tip over require more damage control. Nevertheless, some cleaners grin and bear it -- and take home $50,000 a year.
(7) Flatus Odor Judge
Odor judges are common in the research labs of mouthwash companies, where the halitosis-inflicted blow great gusts of breath in their faces to test product efficacy. But Minneapolis gastroenterologist Michael Levitt recently took the job to another level-or, rather, to the other end. Levitt paid two brave souls to indulge repeatedly in the odors of other people's farts. (Levitt refuses to divulge the remuneration, but it would seem safe to characterize it thusly: Not enough.) Sixteen healthy subjects volunteered to eat pinto beans and insert small plastic collection tubes into their anuses (worst-job runners-up, to be sure). After each "episode of flatulence," Levitt syringed the gas into a discrete container, rigorously maintaining fart integrity. The odor judges then sat down with at least 100 samples, opened the caps one at a time, and inhaled robustly. As their faces writhed in agony, they rated just how noxious the smell was. The samples were also chemically analyzed, and-eureka!-Levitt determined definitively the most malodorous component of the human flatus: hydrogen sulfide.
(8) Cat Food Quality Controller
British man Jon Hanson had what he describes as the worst job in his entire life: quality control on cat food. His task involved several test as he describes. Test 1: Bury face in a huge tub of it and sniff it to make sure it's fresh. Test 2: Plunge arms in it up to the elbows and grope for bony bits and take them out. Test 3: Scoop up huge dollop of it, smear it flat on surface and prod it with fingers to test how much gristle is there. Uggghh!
(9) Roadkill Remover
Pretty self-explanatory. Roadkill collectors not only have the job of peeling the remains of dead creatures in decay off the road in various states, they also get to do it while braving oncoming traffic.
(10) Monkeys Chaser at a Safari
Marin from Canada was hired to work in a safari zoo. He had to be caged-in in a car and drive around from one reserve to the next. Monkeys always climb on top of the car and usually enjoy a free ride for a while. At the exit of the monkey reserve is a zoo worker equipped with a stick. His duty is to prevent monkeys from leaving the reserve on a car. Imagine chasing monkeys in the glowing sun for eight hours.
Janitor, in itself, is a pretty bad job. But, porno theater janitor is the worst job on the list. The main responsibility of the porno theater janitor is to take his mop and rag and wide up after each show is finished. Unlike a traditional theater, it's safe to assume that sticky substance under the chair is something other than Coca-Cola Classic!

Polar bear hair or loo roll? Shark skin or cheese grater? Welcome to the animal kingdom in extreme close-up
Viewed at extreme magnifications of 1,000 times or more, the natural world acquires a surreal beauty, rich with astonishing forms and spectacular patterns.
A new book, Nano Nature, gives us a rare glimpse into this bizarre 'nano' world. Using a scanning electron microscope (SEM), which can view objects at extreme magnification, Nano Nature explores this hidden world, revealing the complexity behind things we take for granted - a butterfly wing, a polar bear's hair or a fruit fly's eye.
The images are produced in monochrome and then hand tinted to enrich their detail.
It may look like a toilet roll, but these tubes are polar bear 'guard' hairs - the coarse outer layer that protects the finer under-fur from the elements. Although they look white, they are translucent and each air-filled hollow heat-proofs the bear
These sharp, jagged 'teeth' could easily be mistaken for an earth-digging machine, or some giant cheese grater, but they are, in fact, the tiny scales on the skin of a shark, composed of dentines - a tough material denser than bone and tough enough to graze metal. The top is coated with smooth enamel, providing a tough but flexible chain-mail coat of armour, preventing barnacles and parasites from attaching to them
A fruit fly's eyes are made up of many individual 'ommatidia' units, stacked together in a dome, with each functioning as a separate lens, producing multiple images that overlap to create a usable picture. Despite this, however, the fly still only has blurred vision, which is nowhere near as sharp as that of a mammal - more a mosaic interpretation rather than a full 'picture' like a photograph
Is this the vertiginous drop into the well of a spiral staircase or the tendril twists of a fire-fighter's hose? In fact, it is neither. It is the tight curl of a hummingbird hawkmoth's tongue, or 'proboscis', which is made of two flexible rods, with a muscular pump at the top of the passage, used to suck nectar from flowers. Rather then carry about an ungainly stalk, the moth is able to curl up its tongue and store it discreetly under its head until needed and, in some instances, the moths' tongue, when extended, is many times the length of its body
