South Pole scientists activate IceCube neutrino observatory

by Kraig Becker on

The South Pole may be as geographically far away from Santa’s home as is possible, but that didn’t prevent Christmas from coming early to the scientific base that is located there. Last week, researchers completed construction of the IceCube Project, which has been five years in the making and promises an unprecidented look into the very nature of the cosmos.

The IceCube Neutrino Observatory has been built under the Antarcitc ice –8000 feet under the ice to be precise, in hopes of detecting the elusive sub-atomic particles that seem to have some link to the violent cosmic events that may have created the Universe. So far, only about a dozen neutrinos have ever been detected, but researchers hope to change that with this $279 million project.

IceCube uses special sensors, called Digital Optical Monitors, to look for the neutrinos, which leave a distinct radiation signature behind when they collide with oxygen atoms in the ice. Those collusions result in a tell-tale trace of blue light that the obeservatory can track back to the origin of the particle which will help scientists to better understand how the neutrinos are generated in the first place.

Neutrinos are a bit of an anomoly in the Universe, as they are unique paritcles that carry a neutral charge and rarely interact with other particles. They seem to pass through the cosmos, and our planet, without regard to other forces, with their origins and purpose largely a mystery. The completion of the IceCube Project should give scientists the opportunity to observe the particles more closely and possibly take steps toward a better understanding of the Universe itself.

Prehistoric balls may have built Stonehenge

by Sean McLachlan on


There have been a lot of theories over the years about how Stonehenge was built. Moving massive stones ranging from 4 to 45 tons over hundreds of miles isn’t easy in modern times, and certainly was a challenge 4,500 years ago. The two leading theories–log rollers and wooden sledges greased with animal fat–both have detractors. Many archaeologists believe rollers would have left deep scars in the landscape and one can be found, while reenactments with sledges have shown it would take hundreds of people to move the largest stones.

Now National Geographic reports a new theory. British graduate student Andrew Young thinks grooved wooden rails fitted with stone balls would have made an easy surface on which to move the stones. The balls acted like ball bearings and giant stones could have been pulled along on top. He tried it out with a team of seven people and found they could easily move a load of four tons. Only a relatively short length of track would be needed because the rails and balls could be pulled up once the stone passed and placed at the front.

He got the idea by studying mysterious stone balls found near stone circles in Scotland. They didn’t appear to have any purpose until he noticed they’re all exactly 70mm (3 inches) in diameter, suggesting they were part of some greater mechanism.

It’s an interesting idea, but this former archaeologist isn’t convinced yet. No stone balls have been found in England. Young says old-growth wood could have worked just as well and wouldn’t have survived, and that’s possible, but civil engineer Mark Whitby told National Geographic that the biggest stones in Stonehenge would have crushed the balls into the tracks. A larger-scale demonstration is being planned to study this issue.

Generally the KISS method (Keep It Simple, Stupid) points to the most probable solution. Wood was plentiful and making smooth rollers out of tree trunks would have been the easiest solution. Rollers and a bunch of strong prehistoric Britons, helped by teams of oxen, would have been the cheapest and least technologically demanding way to move the stones. While this would have left marks on the land, it’s an open question whether they’d still be visible after 4,500 years of weathering.

The KISS method also explains why aliens didn’t build Stonehenge.

The balls idea is still worth investigating, and considering that Young has come up with such an innovative and perhaps correct answer to a major archaeological mystery while still a PhD student in biosciences hints that I’ll be writing more about him in the future.

Ancient statue of decapitated ballplayer discovered in Mexico

by Sean McLachlan on

One of the most enduring puzzles vexing archaeologists is the Mesoamerican ballgame. Played for 3,000 years by several cultures until the Spanish conquest, it had deep religious significance, although archaeologists are unsure just what that means.

Two teams faced off in a rectangular stone ball court, trying to knock a solid rubber ball using everything except their hands. At the end one team (presumably the losers) were sacrificed to the gods. Why? Nobody is really sure.

Now a new piece has been added to the puzzle. Archaeologists working at the site of the ancient settlement of El Teúl in the Zacatecas region of central Mexico have uncovered the statue of a headless ballplayer. El Teúl was inhabited for 1,800 years, longer than any other major site in the area.

The statue was found in the remains of an ancient ball court. Archaeologists theorize the statue acted as a pedestal on which to put real heads. Give me that old-time religion!

No good photo is available at this time, although you can see a shot of it lying where it was found in this article. The new find looks very different from the famous stele of a decapitated ballplayer shown here from the Anthropology Museum of Xalapa, Mexico.

If you want to try to figure out just what all the ballplaying and beheading was about, you’ll have your chance in 2012 when El Teúl opens to the public. Mexico is filled with ancient sites, and history buffs will soon have another important one to visit.

Roman village discovered in London suburb

by Sean McLachlan on


Archaeologists working in the west London suburb of Brentford have discovered a Roman village.

The 2,000 year-old village was along a road leading out of London (called Londinium back then) to Silchester, another Roman settlement. Archaeologists found several houses, a stretch of the original road, plus numerous burials and artifacts. The site is located on the grounds of Syon House, the stately home of the Duke of Northumberland.

This isn’t the first find on the Duke’s property. For the past six years an archaeology team has been excavating a medieval abbey there.

The excavation that found the Roman site was done to clear the way for a new Waldorf Astoria hotel. Some of the artifacts will be on display at the hotel once it opens later this year.

Despite being a massive city that’s been built, burned, rebuilt, bombed, and rebuilt again, London has managed to retain some remnants of its Roman past. A mithraeum, a temple dedicated to the god Mithras, is right downtown at the corner of Queen St. and Queen Victoria St., as you can see in the above picture. There are stretches of Roman wall nearby and an excellent display of artifacts in the Museum of London.

Strangely, the announcement of this discovery came at the same time as an announcement by Egyptologists of a discovery of a sphinx-lined road under an apartment complex in Luxor, Egypt. Makes you wonder what’s underneath your basement.

Afghan archaeologists race to study Buddhist site before destruction

by Sean McLachlan on

We all remember the Bamiyan statues, those giant stone Buddhas the Taliban blew up in 2001. One of the 1,500 year-old statues is pictured here. Pictures are all we have left of them.

Now another Buddhist site in Afghanistan is under threat of destruction. This time the danger isn’t the Taliban, but a Chinese mining company. The site of Mes Aynak in eastern Afghanistan was home to a thriving Buddhist monastery in the seventh century. It’s also right next to an abandoned Soviet mine that may have the world’s second-largest reserve of copper. A Chinese mining company has invested $3.5 billion to exploit the mine and Afghan officials are eager for work to get underway.

A team of Afghani archaeologists is busy excavating the site and has found an entire monastery complex with more than 150 statues. They were originally given three years, a woefully inadequate length of time for a team of barely forty people, and now they’re being pressured to finish by the end of this year. The archaeologists fear that once the miners move in, the monastery will get wrecked.

The mine will bring much-needed jobs and wealth to Afghanistan, which is also courting adventure tours, so the in the rush to yank copper out of their land they might want to think about preserving some of their past.
