Argentine ants living in vast numbers across Europe, the US and Japan belong to the same interrelated colony, and will refuse to fight one another.

The colony may be the largest of its type ever known for any insect species, and could rival humans in the scale of its world domination.

What’s more, people are unwittingly helping the mega-colony stick together.

Argentine ants (Linepithema humile) were once native to South America. But people have unintentionally introduced the ants to all continents except Antarctica.

These introduced Argentine ants are renowned for forming large colonies, and for becoming a significant pest, attacking native animals and crops.

In Europe, one vast colony of Argentine ants is thought to stretch for 6,000km (3,700 miles) along the Mediterranean coast, while another in the US, known as the ‘Californian large’, extends over 900km (560 miles) along the coast of California. A third huge colony exists on the west coast of Japan.

While ants are usually highly territorial, those living within each super-colony are tolerant of one another, even if they live tens or hundreds of kilometres apart. Each super-colony, however, was thought to be quite distinct.

But it now appears that billions of Argentine ants around the world all actually belong to one single global mega-colony.

Researchers in Japan and Spain led by Eiriki Sunamura of the University of Tokyo found that Argentine ants living in Europe, Japan and California shared a strikingly similar chemical profile of hydrocarbons on their cuticles.

But further experiments revealed the true extent of the insects’ global ambition.

The team selected wild ants from the main European super-colony, from another smaller one called the Catalonian super-colony which lives on the Iberian coast, the Californian super-colony and from the super-colony in west Japan, as well as another in Kobe, Japan.

They then matched up the ants in a series of one-on-one tests to see how aggressive individuals from different colonies would be to one another.

Ants from the smaller super-colonies were always aggressive to one another. So ants from the west coast of Japan fought their rivals from Kobe, while ants from the European super-colony didn’t get on with those from the Iberian colony.

One big family

But whenever ants from the main European and Californian super-colonies and those from the largest colony in Japan came into contact, they acted as if they were old friends.

These ants rubbed antennae with one another and never became aggressive or tried to avoid one another.

In short, they acted as if they all belonged to the same colony, despite living on different continents separated by vast oceans.

The most plausible explanation is that ants from these three super-colonies are indeed family, and are all genetically related, say the researchers. When they come into contact, they recognise each other by the chemical composition of their cuticles.

“The enormous extent of this population is paralleled only by human society,” the researchers write in the journal Insect Sociaux, in which they report their findings.

However, the irony is that it is us who likely created the ant mega-colony by initially transporting the insects around the world, and by continually introducing ants from the three continents to each other, ensuring the mega-colony continues to mingle.

“Humans created this great non-aggressive ant population,” the researchers write.

This summer, how would you like to lean back in your lawn chair and toss back a brew made from what may be the world’s oldest recipe for beer? Called Chateau Jiahu, this blend of rice, honey and fruit was intoxicating Chinese villagers 9,000 years ago—long before grape wine had its start in Mesopotamia.

University of Pennsylvania molecular archaeologist Patrick McGovern first described the beverage in 2005 in the Proceedings of the National Academy of Sciences based on chemical traces from pottery in the Neolithic village of Jiahu in Northern China.  Soon after, McGovern called on Sam Calagione at the Dogfish Head Craft Brewery in Milton, Del., to do the ancient recipe justice. Later this month, you can give it a try when a new batch hits shelves across the country.  The Beer Babe blog was impressed, writing that it is “very smooth,” and “not overly sweet.”

But that’s not the only strange brew Dogfish is shipping out this summer.  Next week, the brewery will be bottling up the first large batch of Sah’tea for the general public—a modern update on a ninth-century Finnish beverage. In the fall, The New Yorker documented the intricate research and preparation that went into making the beer, which was first offered on tap at the brewery in May. In short, brewmasters carmelize wort on white hot river rocks, ferment it with German Weizen yeast, then toss on Finnish berries and a blend of spices to jazz up this rye-based beverage.  Reviewers at the BeerAdvocate universally praised Sah’tea, comparing it to a fruity hefeweizen.  One user munched on calamari as he downed a pint and described the combo as “a near euphoric experience.”

And Dogfish is also bringing back one of their more unusual forays into alcohol-infused time travel. Called Theobroma, this cocoa-based brew was hatched from a chemical analysis of 3,200-year-old pottery fragments from the Cradle of Chocolate, the Ulua Valley in Honduras. Archaeologist John Henderson at Cornell University first described the beverage in 2007 in the Proceedings of the National Academy of Sciences, pushing the first use of the chocolate plant back by 600 years. Dogfish first sold Theobroma in May 2008, and the next batch—made from a blend of cocoa, honey, chilies, and annatto—will be on shelves and in taps in July.  The chocolate beer was apparently too sweet for Evan at The Full Pint, who writes that it contained “a ton and a half of sugary sweetness” with “an insane amount of gooeyness left behind on the roof of your mouth.”

Gorgeous I tell ya. Gorgeous.

Scientists say they have found a primate fossil that shows our connection with other mammals and our earliest human ancestor. Full details from the University of Oslo and the Senckenberg Research Institute:

Scientists announced on Tuesday in New York the discovery of a 47 million year old human ancestor. For the past two years, an international team of scientists, led by world-renowned Norwegian fossil scientist Dr Jørn Hurum, University of Oslo Natural History Museum, has secretly conducted a detailed forensic analysis of the extraordinary fossil, studying the data to decode humankind’s ancient origins. At 95% complete, Ida is set to revolutionize our understanding of human evolution.

Discovered in Messel Pit, Germany, the fossil is twenty times older than most fossils that explain human evolution. Known as ‘Ida’, the fossil is a transitional species showing characteristics from the very primitive non-human evolutionary line (prosimians, such as lemurs), but she is more related to the human evolutionary line (anthropoids, such as monkeys, apes and humans). This places Ida at the very root of anthropoid evolution - when primates were first developing the features that would evolve into our own. The scientists’ findings are published by PLoS ONE, the peer reviewed open access journal from the Public Library of Science.

Unlike Lucy and other famous primate fossils found in Africa’s Cradle of Mankind, Ida is a European fossil, preserved in Germany’s Messel Pit; the mile-wide crater and oil-rich shale is a significant site for fossils of the Eocene Epoch. Fossil analysis reveals that the prehistoric primate was a young female. Opposable big toes and nails confirm the fossil is a primate, and a foot bone called the talus bone links Ida directly to humans.

The fossil also features the complete soft body outline as well as the gut contents; a herbivore, Ida feasted on fruits, seeds and leaves before she died. X-rays reveal both baby and adult teeth, and the lack of a ‘toothcomb’ or a ‘toilet claw’ which is an attribute of lemurs. The scientists estimate Ida’s age when she died to be approximately nine months, and she measured approximately three feet in length.

Ida lived 47 million years ago at a critical period in Earth’s history. It fell within the Eocene Epoch, a time when the blueprints for modern mammals were being established. Following the extinction of dinosaurs, early horses, bats, whales and many other creatures including the first primates thrived on a subtropical planet. The Earth was just beginning to take the shape that we know and recognise today - the Himalayas were being formed and modern flora and fauna evolved. Land mammals, including primates, lived amid vast jungle.

Ida was found to be lacking two of the key anatomical features found in lemurs: a grooming claw on the second digit of the foot, and a fused row of teeth in the middle of her lower jaw known as a toothcomb. She has nails rather than the claw typical of non-anthropoid primates such as lemurs, and her teeth are similar to those of monkeys. Her forward facing eyes are like ours - which would have enabled her fields of vision to overlap, allowing 3D vision and an ability to judge distance.

The fossil’s hands show a humanlike opposable thumb. Like all primates, Ida has five fingers on each hand. Her opposable thumb would have provided a ‘precision grip’. In Ida’s case, this is useful for climbing and gathering fruit; in our case, it allows important human functions such as making tools, and writing. Ida would have also had flexible arms, which would have allowed her to use both hands for any task that cannot be done with one - like grabbing a piece of fruit. Like us, Ida also has quite short arms and legs.

Evidence in the talus bone links Ida to us. The bone has the same shape as in humans today. Only the human talus is obviously bigger. X-rays, CT scanning and computer tomography reveal Ida to be about nine months old when she died, and provide clues to her diet - which included berries and plants. Furthermore the lack of a bacculum (penis bone) means that the fossil was definitely female.

X-rays reveal that a broken wrist may have contributed to Ida’s death - her left wrist was healing from a bad fracture. The scientists believe she was overcome by carbon dioxide gas whilst from drinking from the Messel lake: the still waters of the lake were often covered by a low lying blanket of the gas as a result of the volcanic forces that formed the lake and which were still active. Hampered by her broken wrist, Ida slipped into unconsciousness, was washed into the lake, and sunk to the bottom, where unique preservation conditions preserved her for 47 million years.

Around the world, in places as diverse as Homestead, Florida and Yonaguni, Japan stand monuments and ruins whose origins are shrouded in mystery. Nobody knows exactly why Stonehenge was built, how a set of manmade ruins came to be submerged deep in the ocean or who commissioned a giant carved granite set of post-apocalyptic instructions for rebuilding society on a remote hill in Georgia.

On a barren knoll in northeastern Georgia stands one of the world’s most bizarre and mysterious monuments. But it wasn’t created during ancient times. Known as the ‘Georgia Guidestones’, this stone structure of five 16-feet-tall, 20-ton slabs of polished granite is inscribed in eight languages – including Egyptian Hieroglyphics, Hindi and Swahili - with instructions for dazed post-apocalyptic survivors attempting to rebuild civilization. It’s oriented to track the sun’s east-west migration year-round, and has holes that allow gazers to locate the North Star. The Georgia Guidestones were commissioned by an anonymous group, whose identity remains a mystery.

A group of researchers using sonar to look for shipwrecks at the bottom of Lake Michigan got quite a surprise when they found what appears to be an ancient Stonehenge-like structure 40 feet beneath the surface of the water. Some of the stones are arranged in a circle and one appears to show carvings of a mastodon. The formation could be as much as 10,000 years old, which is coincident with the post-Ice Age presence of both humans and mastodons in the area. Michigan already has petroglyph sites and standing stones.

Recycling Our Way to a More Sustainable Future

After half a century of searching, scientists have finally discovered what happens to the world’s second largest shark every winter: It has a Caribbean hideout.

Basking sharks, which can grow up to 33 feet long and weigh more than a Hummer H1, spend the late spring, summer and early fall in the temperate regions of the world’s oceans. But then they pull their great disappearing act, eluding scientists throughout the winter months.

“It’s been a big mystery for the past fifty years,” said Greg Skomal, an aquatic biologist at the Massachusetts Division of Marine Fisheries and lead author of the study in Current Biology May 7. “For a while people thought they were hibernating on the sea floor, even though hibernating is not really something sharks do.”

Skomal tagged the giant fish off the coast of Cape Cod, Massachusetts and tracked them by satellite, piecing together their mysterious winter wanderings. He discovered the beasts were absconding to the depths of the Caribbean, some voyaging as far as the Brazilian coast, though the attraction of these destinations poses yet another mystery. The findings have implications for conserving the sharks, whose fins are much-desired delicacies in Chinese cuisine.

The basking shark is a benign behemoth. It swims at about three miles per hour with its four-foot-wide mouth gaping open, filtering through almost 500,000 gallons of water every hour for its plankton sustenance.

Like most large fish, they’re difficult to keep track of because they rarely come to the surface, where tags need to be to transmit information to satellites. Skomal got around this hurdle by harpooning the fish with special tags that tracked and stored depth, temperature and light level, which then popped off at a pre-programmed date and rose to the surface. Once a tag hits the surface, it transmits the entire archive of the fish’s journey via satellite. Skomal used a novel analysis technique that could determine the sharks’ locations at every time point, allowing him to retrospectively track them to their secret hiding places.

He found the sharks were traveling well-outside their known range, spending months in the warm waters of the Caribbean and even deep into the southern hemisphere. They also periodically dove to more than 3,000 feet, and often stayed at those depths for months at a time. One shark remained at a depth of nearly 600 feet for upward of five months.

“What they’re doing there — therein lies the mystery,” said Skomal. “If you’re a basking shark you can go to Georgia in the wintertime and be at the right temperature and depth and have plenty of food, so that’s optimal. So why travel three to four times that distance?”

He hypothesizes the trip may have to do with reproduction, another area that has long baffled basking shark researchers.

“No one has ever seen a baby basking shark, no one’s found a pregnant shark, knows when they reproduce or what their gestation period is,” said Skomal.

One possibility, he said, is that the sharks mate in the waters further north, where food and potential mates are plentiful. Then the females may migrate to the deep waters down south, which provide a stable and predator-free environment for the young sharks to grow.

“It’s really hypothetical,” he acknowledged. “We don’t know the genders of the sharks we tagged because we tagged them from the boat. Next time we’ll jump into the water so we can pull down their fly.”

The extended range of the sharks suggests that the different Atlantic subpopulations — near the east and west coasts of both hemispheres — may actually be the same population.

“They might even be crossing into other oceans,” he said, “meaning there might actually be one population in the entire world.”

This possibility has implications for conservation biologists. The sharks are currently listed as “vulnerable” on the IUCN Red List of Threatened Species, due to the high value of their fins which are the key ingredient for shark fin soup, a tasteless but symbolic Chinese delicacy. The sharks’ livers, which can make up 25 percent of their total body weight, also fetch a high price for their oil.

“This tells us that if we allow sharks off British Columbia to be harvested, we might be impacting the entire population,” said Skomal. “We can’t just save the fish off of New England, we have to coordinate with all the fisheries. We have to divide up the pie instead of each having our own pie.”
