Virgin Shark Gives Birth!

Female sharks may not need males around anymore, because they can reproduce without having sex, surprised scientists have found.

The startling discovery, announced today, has a long history. It was initially made after the unexpected birth of a baby hammerhead shark in the aquarium of Nebraska's Henry Doorly Zoo in December 2001. The birth surprised zookeepers because the tank only contained female hammerheads, none of which had ever even been exposed to a male during their time in captivity, much less mated with one.

Snake Cults Dominated Early Arabia

Pre-Islamic Middle Eastern regions were home to mysterious snake cults, according to two papers published in this month's Arabian Archaeology and Epigraphy journal.

From at least 1250 B.C. until around 550 A.D., residents of what is now the Persian Gulf worshipped snakes in elaborate temple complexes that appear to have been built for this purpose, the studies reveal.

Hidden Tombs of Ancient Syria

Although nearly seven years have passed, I still vividly remember the events of June 10, 2000. Our archaeological team of students and specialists, about fifteen strong, had begun the third week of a two-month excavation season on the Jabbul Plain of northern Syria. We were bracing ourselves for the hot and dry summer days we could expect at our site, Tell Umm el-Marra. A tell (the word means "mound" in Arabic) is not a natural feature. Rather, it is an archaeological time capsule, with layers of mud bricks, stones, artifacts, and other materials that have accumulated for thousands of years as buildings were lived in, abandoned, fell into ruin, and finally served as the foundations for a new generation of buildings. At Tell Umm el-Marra the remains have accumulated to a height of twenty-seven feet across an area of fifty acres. The mound is one of scores that dot the otherwise featureless plain.

T. Rex's Secret Weapon Discovered

A paleo-bully of sorts, a Tyrannosaurus rex could chomp down on prey with the force needed to lift a semi-trailer, tearing apart a victim's bones. Now researchers have discovered the dino's secret weapon: it was hard-headed.

"Fused, arch-like nasal bones are a unique feature of tyrannosaurids," said lead scientist Eric Snively of the University of Alberta. "This adaptation, for instance, was keeping the T. rexes from breaking their own skull while breaking the bones of their prey."

Bay dolphins have Welsh dialect

Bottlenose dolphins are talking to each other using a dialect that could be unique to Wales, claim scientists.

The whistles of dolphins in Cardigan Bay are different to those living off the Irish coast, a study has found.

A plan to build a giant liquid telescope on the moon

Even by astronomical standards, Roger Angel thinks big.

Angel, a leading astronomer at the University of Arizona, is proposing an enormous liquid-mirror telescope on the moon that could be hundreds of times more sensitive than the Hubble Space Telescope.

The Large Zenith Telescope in British Columbia has a 6-meter primary liquid mirror

Drifters could explain sweet-potato travel

How did the South American sweet potato wind up in Polynesia? New research suggests that the crop could have simply floated there on a ship.

The origin of the sweet potato in the South Pacific has long been a mystery. The food crop undisputedly has its roots in the Andes. It was once thought to have been spread by Spanish and Portuguese sailors in the sixteenth century, but archaeological evidence indicates that Polynesians were cultivating the orange-fleshed tuber much earlier than that, by at least AD 1000. However, there's no hard evidence of people travelling between South America and the South Pacific so early in history. Most Polynesian crops have their origins in Asia, where the people are thought to have migrated from.

Comment: Traditional science who reject ancient high civilisations before The Sumerians have trouble explaining many anormalies. Maybe they should read The Secret History of the World
