1 . Researchers in Norway say they have found what they believe is the world’s oldest runestone (符文石)—a stone with ancient writing on it.

Runes are the characters in several Germanic letters. These characters were used in northern Europe from ancient times until the change to the Latin letters. The origin of runic writing is unclear. The Norwegian researchers say the writing on the runestone could be up to 2,000 years old.

The runestone is square and flat. The runes carved into it may show the earliest example of recorded words in Scandinavia, the Museum of Cultural History in Oslo said. It said it was “among the oldest runic writings ever found” and “the oldest runestone ever found in the world”.

Kristel Zilmer is a professor at University of Oslo, of which the museum is part. Zilmer said, “This find will give us a lot of knowledge about the use of runes in the early Iron Age. This may be one of the first attempts to use runes in Norway and Scandinavia on stone.”

Runes have been found on stones and on home goods. Older runes have been found on other objects, also, but not on stones. The oldest known runic writing is on a hair tool made from bone. Zilmer said that the ancient writer might have used a knife or needle to make the runes.

Measuring 31 centimeters by 32 centimeters, the stone has several kinds of writings. Not all of them make sense. Eight runes on the front of the stone read “idiberug”—which could be the name of a person or family but not sure.

There is still a lot of research to be done on the rock, named Svingerud stone after where it was found.

The Museum of Cultural History is going to hold a public showing of the runestone for a month. The museum holds Norway’s largest collection of historical objects, from ancient times to the modern day.

4 . The city of Pompeii is a partially buried Roman town­city near modern Naples in the Italian region of Campania. Along with Herculaneum, Pompeii was partially destroyed and buried under 4 m to 6 m of ash in the eruption of Mount Vesuvius in 79 AD.

By the 1st century AD, Pompeii was one of a number of towns located near the base of the volcano, Mount Vesuvius. The area had a large population which grew prosperous(繁荣的) from the region’s agricultural fertility(丰产). Many of Pompeii’s neighboring communities also suffered damage or destruction during the 79 AD eruption. The eruption occurred on August 24.

A study of the eruption products and victims indicated that at Vesuvius and surrounding towns heat was the main cause of death of people, previously believed to have died by ash suffocation(窒息). The results of the study, published in 2010, show that exposure to at least 250 ℃ hot surges at a distance of 10 kilometres from the vent(出口) was sufficient to cause instant death, even if people were sheltered within buildings.

In 1748, a farmer called Andre and his brother dug a cupboard made of metal. To their surprise, there are a lot of dissolved jewelry and ancient money in it.

This news took air. The farmers were thinking of the legend of disappeared Pompeii that ancestors told them. So, many archaeologists, historians, and even treasure hunters swarmed(蜂拥) there. In 1876, Italy government agreed with experts to dig the Pompeii out. Through a hundred years’ working, they dug the Pompeii out completely.

The historian Vanya said, “What a horrifying scene! Many people died when they are dormant(休眠的), and some people died behind the door of home. They were raising their hands and breathing ...”

Compared with nature, human seems small and weak. We don’t have enough power to compete with nature, so we should respect nature and protect the environment to lessen disasters.

5 . According to a new research, published in the journal Nature by a team from the University of Liverpool, humans were building structures made of wood, dating back at least 476,000 years ago. The research team found well-preserved wood at the site of Kalambo Falls, Zambia. Stone tool cut-marks on the wood show that these early humans shaped and joined two large logs (原木) to make a structure, probably the foundation of a platform. This is the earliest evidence in the world of the designed arrangement of logs to fit together.

Until now, evidence for the human use of wood was limited to its use for making fire, digging sticks and other tools. Wood is rarely found in such ancient sites as it usually rots and disappears, but at Kalambo Falls permanently high water levels kept the wood.

This discovery challenges the prevailing view that Stone Age humans were moving around. Here humans not only had a constant source of water, but the forest around them provided enough food to enable them to settle and make structures. Professor Larry Barham, from the University of Liverpool, who leads the “Deep Roots of Humanity” research project said, “This find has changed how I think about our early ancestors. They used their intelligence, imagination, and skills to create something they’d never seen before, something that had never previously existed.”

The special new luminescence (冷光) dating technique was carried out by experts, which explains the last time materials in the sand surrounding the finds were exposed to sunlight, to determine their age. This research forms part of the pioneering “Deep Roots of Humanity” project. Professor Barham added, “Kalambo Falls is an extraordinary site in Zambia. The Deep Roots team is looking forward to more exciting discoveries coming from its waterlogged sands.”

7 . Lisa St. Coeur Cormier, a high school science teacher in Prince Edward Island (PEI), Canada, found a tree root. When she took a closer look, she found the shape was very strange. She realized it wasn’t a tree root though it shared the same color. She felt it was hard to break and noticed an impression of bones of what looked like some kind of animal.

Cormier sent a photo of the find to Laura MacNeil who used her knowledge in this field to confirm that what Cormier had seen really was a fossil (化石). MacNeil runs tours of sites where prehistoric fossils have been found and also helps people identify fossils. She visited the site of Cormier’s find to take more photos of it.

MacNeil contacted John Calder, a scientist, who examined the fossil and led a team of scientists to study it. John Calder said it could be as much as 300 million years old. He said it’s probably from a reptile (爬行动物) of some kind — likely one that is unknown to scientists. Scientists spent 5.5 hours carefully digging out the fossil from the ground so they could study it more in-depth and find out exactly what kind of animal it is. That research could take a year or more.

“This is an important discovery here on Prince Edward Island. It is the second of the only two articulated skeletons (关节相连的骨头) found on PEI,” Laura MacNeil said. “This creature lived about 300 million years ago. This find tells us there is a great possibility for future scientifically important fossils that could be discovered on PEI. It will lead to more researchers paying a visit.”
