Was This The Real Mona Lisa?

by Sean McLachlan on

Scientists in Florence are examining the bones of a 16th century nun they think served as the model for the Mona Lisa.

Lisa Gherardini Del Giocondo was the wife of a wealthy merchant and is rumored to have been the model for Leonardo da Vinci’s famous portrait. She was a famed beauty in her time and lived across the street from the famous artist and inventor. When her husband died she became a nun at the convent of San Orsula in Florence, where she died and was buried in 1542.

A team of scientists went looking for her in a crypt under the convent. DNA in the bones they found is now being compared with samples taken from the Gherardini family tomb in hopes of finding a match. The next step will be facial reconstruction to see what the woman looked like in life. Perhaps they’ll find the mystery to her enigmatic smile.

Facial reconstruction and DNA analysis have already been done for the remains of King Richard III, found last year under an English parking lot. Researchers are also examining the possible remains of King Alfred the Great.

Human-Powered Helicopter Wins Award (VIDEO)

Oh Canada! First you gave us William Shatner, now you give us a human-powered helicopter.

A team of engineers called AeroVelo has won a $250,000 award for creating a human-powered helicopter that could fly three meters off the ground for 60 seconds while keeping the cockpit within a ten-square-meter area. The American Helicopter Society sponsored this Igor I. Sikorsky Human Powered Helicopter Competition, and the prize money has been on offer for nearly 30 years.

Man-powering a helicopter is tough to do since humans don’t have strength to lift themselves off the ground without large rotors. Of course, large rotors are heavy, making it hard for a human to get the helicopter off the ground. This is the reason all those Renaissance-era experiments with birdlike flapping wings never worked. To cut down on weight, the team used super-light materials that are too delicate to be flown outdoors.

AeroVelo’s flight lasted 64.11 seconds, a world record, and reached up to 3.3 meters in altitude. As you can see from the video, drift was a problem with this and all other competitors, with the machine drifting up to 9.8 meters.

So will this be the new way to get to the hockey game? Probably not. The personal jetpack has been around for decades but never took off either. The Martin Jetpack company is trying to change that, although they haven’t yet made their jetpacks — which will probably cost in the six figures — commercially available yet. Popular Mechanics did an interesting article on why jet packs aren’t feasible.

Norwegian Scientists Plan To Freeze Themselves In Polar Ice

by Sean McLachlan on

A hundred and twenty years ago, Norwegian scientist Fridtjof Nansen started a journey that made him one of the greatest explorers of all time. He set out to purposely get his ship frozen in the polar ice.

The reason? To study polar currents. His ship, the Fram, was purpose-built for the task. It needed to be; many crews had perished in the far north when their ships got frozen and then crushed by ice. The Fram spent three years stuck in the ice as the crew studied currents, took soundings and gathered a host of other scientific data that researchers are still sifting through. Not content with this adventure, Nansen set off on skis in a failed bid to be the first to the North Pole.

Nansen (1861-1930) was fascinated with the world of the Arctic. He was the first to ski across Greenland in 1888 and wrote about his adventures in The First Crossing of Greenland. This was the first of many exciting travel books he’d write. His most famous is Farthest North, his account of the Fram expedition. Nansen went on to win the Nobel Peace Prize for his work helping refugees after World War I, including the many victims of the Armenian Genocide. His ship is preserved at The Fram Museum in Oslo.

Now researchers at the Norwegian Polar Institute want to get their own ship frozen in the ice. They’re hoping to take an old Arctic research vessel that’s slated for the scrapyard and get it stuck in the ice during the winter of 2014-15.

They plan on studying the conditions of the ice, conditions that have changed markedly in the past few years. With the warming of the poles, most ice is only a year old, instead of being several years old like the ice that Nansen studied. This young ice is thinner, more saline, and has different reflective properties than older ice. Such a study may yield important data on how the Arctic is changing due to global warming.

Interactive Website Shows Cleanest, Dirtiest European Beaches

by Sean McLachlan on

It’s getting to be that time of year again. People are heading to the beaches, especially around the Mediterranean.

Now choosing one has been made easier by a new interactive website by the European Environment Agency. The agency has released its 2012 figures for water quality of 23,511 “bathing waters.” The website has them broken down by country and region. While most are beaches, popular inland swimming areas such as lakes are also included.

Some countries do better than others. Cyprus may be in economic doldrums, but 100% of their beaches have clean water. Slovenia, the subject of an upcoming series here on Gadling, gets equally high praise for its narrow strip of shoreline.

Scientists examined samples of water over several months in 2012, looking for evidence of pollution. It turns out 93 percent of sites had at least the minimum standard set by the European Union. The worst countries were Belgium, with 12 percent substandard swimming areas, and The Netherlands, with 7 percent.

Archaeologists Digging At Lincoln Castle Uncover Early Christian Community

by Sean McLachlan on

Archaeologists excavating at Lincoln Castle have discovered the remains of an early Christian community, according to a Lincolnshire County Council press release.

The team, which was digging inside the castle to clear the way for an elevator shaft, found the remains of a church that dates back at least 1,000 years. Inside a sealed niche in the wall they found human bones. They had been wrapped in finely woven cloth and while the cloth has long since disappeared, it left its impression on the surrounding mortar. Excavators theorize that these may be the remains of a holy person, as it was common to put relics in church walls and altars in order to make them holy.

An even older find included several skeletons and a stone sarcophagus. The archaeological team is planning to put an endoscopic camera into the coffin to see what’s inside without disturbing it.

%Gallery-188672%Both the cemetery and church date to the Anglo-Saxon period, when England was a patchwork of different kingdoms before the Norman conquest. Lincoln had been a walled Roman town. The Romans left Britain in the early fifth century and were soon replaced by Anglo-Saxons coming from Denmark and northern Germany. They took up residence in Lincoln and many other Roman towns.

The present castle was built by the Normans in 1068 on the foundations of a Roman fort. William the Conqueror, after defeating the English King Harold Godwinson at Hastings in 1066, built this castle to control the important town of Lincoln and its surrounding area. While the castle has been modified over the centuries, it’s still one of the best-preserved Norman castles anywhere.

The typical Norman castle has a tower on an artificial mound at the center and with a wall encircling it. Lincoln Castle has two mounds, each with its own fortification and a long wall encircling them both. This tough fortification was besieged twice. The second time, in 1216, was during the Baron’s War, which led King John into making concessions to the nobility in the form of the famous Magna Carta. One of the original copies is on display here.

Back in 2010, an earlier excavation uncovered a secret tunnel at Lincoln castle. Excavations continue at in the castle grounds.
