When Aaron Krywiak took a job with the city's drainage department, he never imagined he'd be digging up 70 million-year-old dinosaur remains.

But that's what he and work partner Ryley Paul unearthed earlier this month, when they were jack-hammering out a sewer tunnel nine storeys below the ground in west Edmonton.

"We were just digging, doing our jobs, and we found some rocks a couple of weeks ago and we just figured they were interesting looking rocks," Krywiak, 21, said Monday

NASA prepares for asteroid rendezvous

NASA is getting ready for its Dawn spacecraft's encounter with a giant asteroid, set to happen in less than a year, the agency said.

Dawn will conduct a detailed study as it spends a year circling the asteroid Vesta, becoming the first spacecraft to orbit a body in the solar system's asteroid belt, SPACE.com reported Tuesday.

Program Helps Law Enforcement Determine Who Is Most Likely to Commit Crime

New crime prediction software being rolled out in the nation's capital should reduce not only the murder rate, but the rate of many other crimes as well.

Developed by Richard Berk, a professor at the University of Pennsylvania, the software is already used in Baltimore and Philadelphia to predict which individuals on probation or parole are most likely to murder and to be murdered.

In his latest version, the one being implemented in D.C., Berk goes even further, identifying the individuals most likely to commit crimes other than murder.

The ABCs of E-Reading

New Devices Are Changing Habits. People Are Reading More, Even While in a Kayak

People who buy e-readers tend to spend more time than ever with their nose in a book, preliminary research shows.

A study of 1,200 e-reader owners by Marketing and Research Resources Inc. found that 40% said they now read more than they did with print books. Of those surveyed, 58% said they read about the same as before while 2% said they read less than before. And 55% of the respondents in the May study, paid for by e-reader maker Sony Corp., thought they'd use the device to read even more books in the future. The study looked at owners of three devices: Amazon.com Inc.'s Kindle, Apple Inc.'s iPad and the Sony Reader.

While e-readers are still a niche product just beginning to spread beyond early adopters, these new reading experiences are a big departure from the direction U.S. reading habits have been heading. A 2007 study by the National Endowment for the Arts caused a furor when it reported Americans are spending less time reading books. About half of all Americans ages 18 to 24 read no books for pleasure, it found.

Woolly Mammoth Tusks Found in Sea on Show in Dorchester

A pair of 20,000-year-old woolly mammoth tusks trawled up from the bottom of the North Sea are going on display at a Dorset museum.

They form the centerpiece of a display on mammoths at the Dinosaur Museum in Dorchester.

Their tusks could grow to 5m (16ft) but only 1.5m (5ft) sections are on show.

At the time the animal died the North Sea did not exist and the area was low-lying grassland connecting the British Isles to the continent.

When the North Sea formed at the end of the last ice age, the tusks became buried in the thin layers of sand at the bottom of the shallow southern part of it.

They remained there for thousands of years and eventually tidal currents and dredging released the fossilized remains, which were caught in the fishing nets of a trawler earlier this year.

Mexican Archaeologists Extract 10,000 Year-Old Skeleton from Flooded Cave in Quintana Roo

One of the earliest human skeletons of America, which belonged to a person that lived more than 10,000 years ago, in the Ice Age, was recovered by Mexican specialists from a flooded cave in Quintana Roo. The information it has lodged for centuries will reveal new data regarding the settlement of the Americas.

The Young Man of Chan Hol, as the skeleton is known among the scientific community, due to the slight tooth wear it presents, which indicates an early age, is the fourth of our earliest ancestors found in the American Continent, and has been studied as part of a National Institute of Anthropology and History (INAH) project.

After 3 years of studies conducted In Situ to prevent information loss, the Chan Hol skeleton was subtracted from the water by a team of specialists headed by biologist Arturo Gonzalez, coordinator of the project Study of Pre Ceramic Men of Yucatan Peninsula and director of Museo del Desierto de Coahuila (Museum of the Desert of Coahuila), with the participation of speleodivers Eugenio Acevez, Jeronimo Aviles and Luis Garcia, part of the recently founded Instituto de la Prehistoria de America (Institute for American Prehistory), funded by INAH.

The Young Man of Chan Hol, named after the cenote it was found in, was recovered in a 542 meters long and 8.3 deep cave where stalagmites abound, and is reached after going through flooded, dark and difficult labyrinths.

Ancient Human Skeleton Removed from Mexican Cave

The remains of a prehistoric child were removed from an underwater cave in Mexico four years after divers stumbled upon the well-preserved corpse that offers clues to ancient human migration.

The skeletal remains of the boy, dubbed the Young Hol Chan, are more than 10,000 years old and are among the oldest human bones found in the Americas.

The corpse was discovered in 2006 by a pair of German cave divers who were exploring unique flooded sandstone sinkholes, known as cenotes, common to the eastern Mexican state of Quintana Roo.

History Propaganda: Greeks "Discover Odysseus' Palace in Ithaca, Proving Homer's Hero was Real"

An 8th BC century palace which Greek archaeologists claim was the home of Odysseus has been discovered in Ithaca, fueling theories that the hero of Homer's epic poem was real.

Odysseus - known to the ancient Romans as Ulysses - famously took 10 years to return home to Ithaca after the fall of Troy.

On his journey, he was twice shipwrecked and encountered a cyclops, the spirit of his mother and tempting Sirens before returning to Ithaca, where he found his wife, Penelope, under pressure to remarry from a host of suitors who had invaded the royal palace.

With the help of his father, Laertes, and his son, Telemachus, he slaughtered his rivals and re-established his rule.

But despite the fantastical details in the Greek epic, a team of archaeologists has claimed the tale is anchored in truth - and that they have discovered his home on the island of Ithaca, in the Ionian sea off the north-west coast of Greece.

Traces of a Lost Language Discovered

Sometime in the early 17th century in Northern Peru, a Spaniard jotted down some notes on the back of a letter. Four hundred years later, archaeologists dug up and studied the paper, revealing the first traces of a lost language.

"It's a little piece of paper with a big story to tell," says Dr. Jeffrey Quilter, who has conducted investigations in Peru for more than three decades, and is director of the archaeological project at Magdalena de Cao Viejo in the El Brujo Archaeological Complex, where the paper was excavated in 2008. Quilter explains this simple list offers "a glimpse of the peoples of ancient and early colonial Peru who spoke a language lost to us until this discovery."

The writing is a set of translations from Spanish names of numbers (uno, dos, and tres) and Arabic numerals (4 - 10, 21, 30, 100, and 200) to the unknown language. Some of the translated numbers have never been seen before, while others may have been borrowed from Quechua or a related language. Quechua is still spoken today in Peru, along with Spanish, but in the early 17th century, many languages were spoken in the region, such as Quingnam and Pescadora. Information about them today is limited. Even so, the archaeologists were able to deduce that the lost language speakers used a decimal system like our own.

Archaeologists Find New Inscriptions in Ancient City of Pompeiopolis

Turkey, Archaeologists recently discovered new inscriptions during excavations of the ancient city of Pompeiopolis, located in the Taşköprü district of the Kastamonu Province in Turkey's Black Sea region.

The inscriptions are about festivals of the Roman era, Professor Dr. Christian Marek, who has been examining the inscriptions, told national media. According to them, Roman emperors also participated in those festivals, most of which were religious.
