More About Laughter

Every time someone laughs around us, our brains must interpret what it means. As German scientists have discovered, it is more complex than we thought.

A joyful belly laugh is interpreted by the brain in a completely different way from a scornful titter or the giggle from someone being tickled, a group of scientists from Tübingen in south west Germany have found.

In experiments designed to help patients with chronic anxiety disorders, they found that positive non-verbal communication, such as a joyful laugh was processed by a different part of the brain from a negative, scornful snicker.

Laughing is one of the oldest forms of non-verbal communication and is also seen in rats and apes. It could be key to helping patients with psychiatric disorders, who often are unable to correctly interpret non-verbal communication.

Humans have developed several different forms of laughter, each of which can have a complex series of meanings and intentions behind them. “Laughing is a very strong signal in social interaction. If you are laughed at with joy you feel accepted. If you are the victim of scornful laughter, you feel shut out of the group,“ said Dr. Dirk Wildgruber.

In their experiments, Wildgruber and his team played various types of recorded laughter and measured how the sounds were interpreted in the brain. They found that giggles generated when someone is being tickled stimulates areas of the brain responsible for interpreting complex acoustic signals. Happy or scornful laughter, on the other hand, stimulates completely separate brain regions usually tasked with guessing the intentions of others. From there, the laughter kick-starts connections with different parts of the brain depending on the tone - negative or positive.

The next step will be to look into how people with psychological disturbances react to different laughter signals to find out which areas of the brain could be artificially stimulated to help them, said Wildgruber.

Robot Builds Furniture

MIT has built a robot that can assemble IKEA furniture without human intervention. It can assemble flat-pack IKEA furniture all by itself. It has a specialized gripper hand that can grab the pieces and screw them together.

Humans feed the robot a design file that describes the product, such as how many pieces, what do they look like, where the screw holes are, etc. The robots do not need to be instructed how to assemble it. From knowing what the parts look like, the software can decipher how something needs to be put together.

Humpty Dumpty

According to the Oxford English Dictionary, “humpty dumpty” was first used in the 17th century and referred to brandy boiled with ale. In the 1700s, it was also a term used to describe a short, clumsy person. It has also been a nickname attributed to someone who has had too much alcohol, as in brandy boiled in ale.

The nursery rhyme is neither a bottle of alcohol nor a person, it is most likely that the nursery rhyme was intended as a riddle. The answer to the riddle is an egg. Something that, if it rolled off a wall, could not be mended by any number of people. Today, the answer is so well known that the character of Humpty Dumpty is an egg and the rhyme is not considered to be a riddle at all, but a story.

Greenland and Australia

Australia is a continent and also the largest island. Greenland is the second largest island, but not a continent.

There are several accepted factors that classify continents. These factors include tectonic independence from other continents, unique flora and fauna, cultural uniqueness, and local belief in continental status.

Australia rests on its own tectonic plate called the Australian Plate. It has its own unique flora and fauna, with native animals unlike any others in the world. Its inhabitants consider themselves to live on both an island and a continent.

Greenland rests on the North American tectonic plate along with Canada, the United States, and Mexico. It has a number of unique species of plants, but its animals, like reindeer, polar bears, and arctic foxes, can also be found elsewhere. Greenland has its own culture, but considered part of the larger North American arctic culture. Its inhabitants consider themselves islanders.

Australia is part of Britain’s Commonwealth and Greenland is officially part of Denmark.

Australia is about 3 million square miles and the sixth largest country in the world. Greenland is about 834 thousand square miles and the twelfth largest country in the world.

Eighty percent of Greenland is covered by ice. Eighteen percent of Australia is covered by deserts.

84% of Greenlanders live in urban areas and 89% of Australians live in urban areas.
Greenland's one major city is its capital, Nuuk. Inhabitants of both live mostly along the coast.

Greenland’s population is 89% Inuit and 11% Danish and Australia’s population is 92% white, 7% Asian, and 1% Aboriginal.

There are almost 6 migrants leaving Greenland per 1000 people. In Australia, there are almost 6 migrants entering the country per 1000 people.
