Dinosaurs “danced” to attract mates

Like their modern-day bird descendants, ancient dinosaurs used "fancy footwork" or dance-like moves to attract mates, scientists have recently concluded.

An analysis of newfound "scratch marks" on four dinosaur sites in Colorado, United States, has led scientists to conclude that dinosaurs displayed a type of animal mating behavior known as "scraping" – a phenomenon common in modern ground-nesting birds.

"These are the first sites with evidence of dinosaur mating display rituals ever discovered, and the first physical evidence of courtship behavior," study co-author Martin Lockley of the University of Colorado at Denver said. "These huge scrape displays fill in a…

1,500-yr old settlement discovered in Norway

Archaeologists have recently discovered a pre-Viking settlement dating from 1,500 years ago, on the Trondheim Fjord on Norway’s coast.

Following excavation works aimed at expanding Trondheim’s Ørland Airport for jet aircraft, archaeologists working at the site have found the remains of three large longhouses arranged in a U-shape, according to the Norwegian University of Science and Technology (NUST).

The longhouses may have been used for community gatherings, honoring village chiefs and storing food, as evidenced by the remains of several fire pits found in the area, the NUST said.

“This was a very strategic place,” Ingrid Ystgaard, project manager at…

Hacker: NASA covering up existence of aliens, UFOs

Gary McKinnon

Aliens from outer space do exist – but the US government is “airbrushing” them out of photos in a massive cover-up, space hacker Gary McKinnon has alleged.

McKinnon, who has been accused by the US government of hacking government and military databases in 2001 and 2002, now claimed to have found evidence that the National Aeronautics and Space Administration (NASA) deliberately edits its space images and removes evidence of alien UFOs before releasing the images to the public.

In a recent interview with Youtube channel RichPlanetTV, McKinnon claimed to have found documents and image databases purpoting to the…

‘Hydra’ – an ‘immortal’ species?

Humans and animals achieving immortality?

It may sound far-fetched, as every living thing on Earth ultimately ages and dies within a certain period of time.

Scientists in the United States, however, have discovered one animal species that can live seemingly forever without aging.

In a co-authored paper published in the Proceedings of the National Academy of Sciences Journal, Pomona College Biology Professor Daniel Martínez caps a decade of research into freshwater polyps – known scientifically as ‘Hydra’ – with a knack for longevity.

The paper, entitled “Constant mortality and fertility over age in Hydra,” shows the freshwater polyps could live…

Did glaciers or men move Stonehenge?

The giant circular stone formation called Stonehenge, situated in the wilds of Wiltshire, England, has been the subject of mystery for centuries. Until now, scientists and archaeologists are still in debate as to who actually built the giant formation and what it was for.

And as if the mystery’s not enough, scientists seem to be at loggerheads over Stonehenge, as two conflicting theories have arisen about the giant limestones’ origins.

The enigma of how the “bluestones” arrived at Stonehenge was said to have been solved two weeks ago, when experts from the University College London claimed the giant blocks had…
